Una herramienta de apoyo a la docencia de las Matemáticas en los Estudios de Arquitectura
Authors: Reyes Iglesias María Encarnación
Published: December 2021

The fundamental motivation for the proposed action is to improve the understanding of Mathematics by students studying Architecture. In this degree, the singular fact of the little homogeneity of the students occurs, which comes from very different high school modalities and training periods; from scientific profiles to artistic ones. This diversity forces us to pose the teaching objectives in a different way to achieve meaningful group learning, especially in subjects that, such as Mathematics, have a high theoretical content and a certain abstract character.

La motivación fundamental de la acción que se plantea es mejorar la comprensión de las Matemáticas por los alumnos que cursan estudios de Arquitectura. En esta titulación acontece el hecho singular de la poca homogeneidad del alumnado, que procede de modalidades de bachillerato y ciclos formativos muy diferentes; desde los perfiles científicos hasta los artísticos. Esta diversidad obliga a plantear los objetivos docen­tes de una forma diferente para conseguir un aprendizaje grupal significativo, sobre to­do en materias que, como las Matemáticas, poseen un alto contenido teórico y un mar­cado carácter abstracto.

Authors: Rivera Linares Javier , Ábalos Ramos Ana , Domingo Calabuig Débora , Lizondo Sevilla Laura
Published: December 2021

The past state of alarm, due to the global pandemic by COVID-19, which forced people to remain confined in homes for 99 days, revealed the lack of necessary conditions in housing, and the forced alteration of inhabiting them. The experience Inhabiting the post-pandemic, learning from the experience lived at a personal and collective level, aims to add to the reflection on the future of housing. The initiative is materialized through a contest open to all architecture students in the Valencian Community and its transfer to the classroom as a vertical workshop in one of the universities participating in the initiative, relying on the contest tool as an inciter to debate and as learning methodology.

El pasado estado de alarma, consecuencia de la pandemia mundial por la COVID-19, y que obligó a las personas a permanecer confinadas en sus domicilios durante 99 días, puso de manifiesto las carencias de la vivienda y la necesaria alteración de sus condiciones en el habitar. La experiencia ‘Habitar la Post-Pandemia’, aprendiendo de la situación vivida a nivel personal y colectiva, pretende sumar un pequeño granito de arena a la reflexión sobre el futuro de la vivienda. La iniciativa se materializa a través de un concurso abierto a todos los estudiantes de arquitectura de la Comunidad Valenciana y su traslación al aula de proyectos como workshop vertical en una de las universidades participantes utilizando la estrategia de concurso como herramienta estimuladora de debate y configuradora de la propia metodología docente.
De las formas a los flujos: aproximación a un proyecto urbano [eco]sistémico
Authors: Crosas Armengol Carles , Perea Solano Miguel Jorge , Martí Elias Joan Maria
Published: December 2021

The awareness of the effects of climate change set significant challenges to urbanism, requiring transdisciplinary approaches capable of giving efficient responses for the contemporary city and territory. A teaching programme set up in the framework of academic cooperation with other European schools through competitive Erasmus+ projects has explored the potential of urban metabolism at the scale of the urban project. Throughout several courses, the analytical and design reflection on the principles of sustainable development has been addressed at the scale of the urban fragment, testing tools, interpreting strategies and coming up with new design projects, merging rigorous and speculative approaches. Through a continuous exploration among students and teachers, some examples of what could be called [eco]systemic urbanism projects have been discussed and illustrated, going beyond the basic application of environmental standards and technical codes.

La toma de conciencia de los efectos del cambio climático plantea importantes retos al urbanismo y exige aproximaciones transdisciplinares capaces de responder eficientemente en la ciudad y el territorio contemporáneos. Un programa nacido de la cooperación académica con otras escuelas europeas en el marco de los proyectos competitivos Erasmus+ ha explorado el potencial del metabolismo urbano a la escala del proyecto urbano. A lo largo de varios cursos, se ha aproximado una reflexión analítica y propositiva sobre las principios del desarrollo sostenible a la escala del fragmento urbano, ensayando herramientas, interpretando estrategias e inventando proyectos, buscando el equilibrio entre el rigor y la especulación. A través de una continua exploración entre estudiantes y profesores, se han discutido e ilustrado algunos ejemplos de lo que podría denominarse proyecto urbano [eco]sistémico, para ir más allá de la simple aplicación de estándares ambientales y códigos técnicos.
Taller de las Ideas
Authors: Ojos-Moral Jesús de los , Rodríguez-Andrés Jairo , Fernández-Catalina Manuel
Published: December 2021

This publication aims to communicate the teaching experience carried out during the Ideas Workshop; a workshop developed with students from the first courses of Architectural Projects with the purpose of activating the space that substantiates the origin of all creative process: the idea. During four editions a delve into the field of generating ideas was proposed. For this intention, a series of dynamics aimed at exercising intuition and individual evocation, as well as the validation of strategies, the representation of abstract themes and finally the correct presentation of ideas were proposed. The Ideas Workshop intends to complete the teaching of Architectural Projects with a methodology that reinforces the subjective, sensitive, intuitive and intentional assessment of reality as the previous and, at the same time, necessary step when approaching the architectural project.

“She Comes from a Cursed Lineage:” Portrayals of Witchcraft, Wicca, and Satanism in The X-Files
Authors: Doyle White Ethan ,   Academic Publishing
Published: December 2021

One of the most iconic television series of the 1990s, The X-Files drew on religious and folkloric traditions regarding supernatural phenomena for many of its plotlines. Among the themes that the show’s writers turned to repeatedly was witchcraft, using it as a major plot device in six episodes over the course of the series’ eleven season run. While drawing on longstanding ideas about witchcraft arising from European and European-American culture(s), these writers also had to contend with a social environment in which fears of witchcraft had resurfaced in the form of the Satanic ritual abuse hysteria and where various forms of modern religious witchcraft had arisen, often claiming proprietorship of the concept of the witch itself. How the show’s writers chose to portray this topic and navigate around the social issues it posed offers insight into the nature of beliefs about witchcraft present in American culture, especially at the close of the twentieth century.
Philo’s Version of the Origin of the Septuagint
Authors: Ćakić Marina ,   Gnomon Center for the Humanities
Published: December 2021

Philo’s work On the Life of Moses contains the story of the origin of the Septuagint (section 2.8–65). The scholars have examined this passage from two different perspectives: explaining the connection between Mosaic Law and the law of nature (2.12–14 and 2:45–53) or examining the very process of translation (2.25–44). Even though dealing with the different aspects of the story, both groups of scholars have come to the same conclusion: Philo claims that the Torah has universal significance. The starting point of this paper is that the two approaches, when taken separately, are insufficient. They both raise two essential questions. First, considering that Philo was using the LXX and not the Hebrew Bible, could it be possible that his claim that the Torah is “an excellent copy” of the law of nature also refers to LXX? Second, even though the Torah is finally translated into Greek – the lingua franca of its day – why would its laws be relevant for the people outside the Jewish communities? In this paper, the analysis of Philo’s story on the LXX origin is compared with the LXX origin account in the Letter of Aristeas. The comparison will demonstrate that the changes Philo introduces into the story are indicative of his two major concerns: the universality of Mosaic law and divine intervention in the process of translation. The contribution of this paper is the acknowledgment that the two mentioned aspects – the universality of the Mosaic law and the divine intervention in the translation process are dependent on each other. The latter made the LXX not merely a translation but the same Torah that was once already given to Moses. Consequently, if the Hebrew Torah and the LXX are equal in every regard, that would mean that the LXX also perfectly reflects the natural law, which makes it relevant for all people.
Mary Had a Little Ram

Published: December 2021

The Spanish Mission to Dra Abu el-Naga (Proyecto Djehuty) has been working in the Eighteenth Dynasty Theban Tombs of Djehuty (TT 11) and Hery (TT 12) and their environs since 2002. The excavators uncovered a deposit west of the courtyard of TT 11, consisting of a wrapped ram, a wooden coffin, and a dense deposit of pottery sherds. This is possibly one of the earliest excavated animal burials in the Theban area, and unusual in the fact that it is of a ram. This article focuses on exploring and contextualising this rare find of the late Second Intermediate Period/early New Kingdom.
Where Doves Lie
Authors: Hartley Mary , Tristant Yann
Published: December 2021

During recent excavations in the Dendara necropolis, skeletal evidence for at least eight complete turtle doves (Columbidae) was discovered in the burial chamber of a Dynasty 4 tomb. A large number of disarticulated tiny bird bones was found scattered beneath and around a broken Meydum-bowl, buried deep within piles of rubble. Zooarchaeological analysis indicated that at least eight birds had originally been buried. The fact that they were complete and found in a burial chamber in association with a Meydum-bowl suggested they were part of a funerary offering. The depiction of multiple bird species used as funerary offerings in the Old Kingdom tombs at Saqqara and Giza is well documented, indicating that birds were a significant element of the list of funerary offerings. Often the different species of birds were named in the tomb scenes, and frequently pigeons and doves were included. However, very little skeletal evidence exists in the archaeological record to support the theory that pigeons and doves were regularly used as funerary offerings. Therefore, the skeletal remains of eight complete turtle doves in conjunction with a Meydum-bowl found deep within a burial chamber of a provincial tomb adds impetus to the argument that not only they were a very desired component of Old Kingdom funerary offerings in the tombs of the important Saqqara and Giza necropolises, but also in the tombs of provincial officials.
New Ramesside Copy of the Teaching of Amenemhat
Authors: Navratilova Hana
Published: December 2021

A newly excavated ostracon from Abydos bearing the concluding chapter of “The Instruction (a.k.a. Teaching) of King Amenemhat” opens up an interesting enquiry. An ostracon found in the immediate vicinity of a New Kingdom royal memorial temple and carrying an excerpt from a major literary text is an important find, as it develops our insight into New Kingdom educational practices and intellectual quests. The range of ostraca types and text genres appearing in the area of the temple of Ramesses II points to a fully functional temple organization with a building phase and an operational phase, with supplies and literate personnel on site, potentially in different administrative roles. Studies in educational and intellectual pursuits, in turn, are key to expanding our comprehension of the functions—and enjoyment—of Egyptian culture.
Unique Lassoing Scene from the Mastaba of Akhmerutnisut at Giza (G 2184)
Authors: Torres Inês
Published: December 2021

This article analyzes a unique scene from the Giza mastaba of Akhmerutnisut (G 2184), which shows a life-size depiction of the tomb owner holding a rope, ready to throw a lasso. The active participation of the tomb owner in a lassoing scene is unique in the iconographic program of Fifth Dynasty elite tombs. The location of this scene within the mastaba is also unparalleled: it is the first scene on the right (west side) encountered by visitors as they enter the mastaba. To understand this innovative decorative choice, this paper starts by discussing the iconography of lassoing in the Old Kingdom and its meaning in the elite tombs of the same period. The second part of this paper analyzes Akhmerutnisut’s lassoing scene with an analytical framework drawn from visual and material culture studies and focusing on the concepts of monumentality, identity and agency. This study provides a number of possible explanations—none of which are mutually exclusive—to understand why Akhmerutnisut had himself depicted as a monumental lassoer by the entrance of his funerary complex, highlighting the importance of visitor experience and participation in the design of the funerary complexes of the Old Kingdom elite.

Publishing patterns in Pharmacy
Authors: Sandgren Terhi
Published: December 2021

Pharmacy is a multidisciplinary research field that combines natural sciences, health sciences and social sciences to study drugs and pharmaceutical preparations from multiple perspectives. The study explores publishing patterns in pharmacy via bibliometric methods, that is statistical methods applied to study scientific literature. Earlier bibliometric studies focusing on pharmacy have used data from the international citation databases Web of Science and Scopus. In most of these studies, pharmacy has been operationalized by focusing on journals categorized as pharmacy journals. This study provides a new approach to the study of publishing patterns, by using data from institutional Current Research Information Systems (CRIS), and by using pharmacy organizations as the basis of operationalization of pharmacy. It seeks to provide a more comprehensive picture of publishing patterns, since the data covers all publication types used in pharmacy and is not limited to pharmacy journals. The objective of this study is thus to explore whether the selection of databases and operationalization of the discipline affects the results concerning publishing patterns in pharmacy.  The results obtained in this study are very similar to earlier studies utilizing international databases. However, the results show that pharmacy researchers also publish in national languages, and that there are several national journals amongst the core journals that are not covered by the international databases. The multidisciplinary nature of pharmacy can be seen in the wide range of journals in which pharmacy researchers publish their articles.
Co-animation and the Multimodal Management of Contextualisation Problems when Jointly ‘Doing Being’ Others
Authors: Cantarutti Marina N.
Published: December 2021

In everyday interaction, participants speak on their own behalf but may temporarily speak as or on behalf of a figure (i.e. past or fictional self, others or objects). This practice of ‘animation’ can be continued or extended by co-participants in responsive position, resulting in co-animation (Cantarutti, 2020) of the same figure. Animation relies on the successful ascription of roles, participation framework shifts and projected stances to either the here-and-now of interaction or the there-and-then of animated content. In turn, the recognition of a response as a co-animation requires the creation of similarity between animated contributions. Through a multimodal interactional linguistic analysis of 89 cases of co-animation, this paper discusses how participants jointly solve these interactional contextualisation ‘problems’ smoothly through multimodal gestalts of lexico-grammatical, prosodic and gestural detail.

Published: December 2021

La Unión Europea (UE) es una organización en continua evolución desde su creación a mediados del siglo XX. Su capacidad de adaptación a las necesidades generadas por el proceso de integración es encomiable. La UE ha superado obstáculos imponentes, como la crisis derivada del rechazo a la Comunidad Europea de Defensa y la Unión Política Europea; la activa oposición de un titán político como el presidente francés, De Gaulle; diversas crisis económicas y monetarias; el Brexit y el auge del populismo. Constantemente, la UE ha superado las crisis que le afectaban con la introducción de elementos estabilizadores comunes introducidos por el proceso de integración, creando más Europa. En la actualidad se enfrenta a un nuevo reto, la adaptación a un progreso tecnológico brutal que influirá en el modelo de sociedad imperante en las próximas décadas. Ante este reto, la UE pretende crear un Mercado Único Digital europeo, entre otras iniciativas, que evidentemente tendrá una influencia substancial en las relaciones económicas entre sus miembros y a escala internacional. Esta investigación se centra en el análisis del desarrollo europeo en torno al mundo digital y su influencia en la propia esencia de la organización.

Virtual Chemical Engineering: Guidelines for E-Learning in Engineering Education
Authors: Schofield Damian , Lester Edward
Published: December 2021

Advanced three-dimensional virtual environment technology, similar to that used by the film and computer games industry can allow educational developers to rapidly create realistic three-dimensional, virtual environments. This technology has been used to generate a range of interactive learning environments across a broad spectrum of industries.The paper will discuss the implementation of these systems and extrapolate the lessons learnt into general guidelines to be considered for the development of a range of educational learning resources. These guidelines will then be discussed in the context of the development of ViRILE (Virtual Reality Interactive Learning Environment), software which simulates the configuration and operation of a polymerisation plant. This software package has been developed for use by undergraduate chemical engineers at the University of Nottingham.
What Don’t We Know About Interactive Lectures?
Authors: Murphy Roger , Sharma Namrata
Published: December 2021

This article considers aspects of lecturer-student interaction within the context of lectures in higher education. In particular it considers ways in which lectures can involve observable interactions between students and lecturers, and how these sometimes involve novel uses of visualisation supported by modern technologies. It goes on to consider the different ways in which interactive lectures can involve the use of new technologies such as voting systems and SMS messaging from mobile telephones. A full range of types of interactive lectures is reviewed, and the article notes the serious lack of research in existence which can inform thinking about what is a very widely used form of teaching throughout higher education. As well as considering the possible implications for students and lecturers of participating in interactive lectures, this article also goes on to consider ways in which this type of educational situation could be subjected to rigorous research investigations. It is argued that such research needs to focus both on the processes of interactive lectures as well as their impact on student learning outcomes.
Commentary: Situated learning in the Network society
Authors: Krumsvik Rune
Published: December 2021

There is a need to develop a broader view of knowledge for dealing with the way in which new digital trends influence the underlying conditions for schools, pedagogy and subjects. This short commentary article, based on my paper at the NVU-conference 2008, will therefore highlight whether a broader view of knowledge - situated learning, digital literacy and the digital revolution can generate new ways of how we perceive pedagogy within the new educational reform in Norway in particular and the digitized school in general. The focus is particularly angled towards the implications this may have for developing new practises for teachers and students.
Shaping or shaking the learning network? Insights into teaching practices using Virtual Learning Environments
Authors: Habib Laurence , Johannesen Monica
Published: December 2021

This article carries out an analysis of a Virtual Learning Environment (VLE) in an institution of Higher Education using Actor Network Theory (ANT). The ANT perspective is used to help explore the complex processes that come into play when a VLE is introduced in an organisation, especially as pedagogical goals, administrative procedures and technological artefacts are interwoven in a heterogeneous web or “network”. The article identifies new actors that emerge in the traditional teacher-student, teacher-teacher and student-student relationships as a result of the presence and active usage of the VLE. It also describes how already existing actors may change roles or status in connection with VLE use.
Inhibition of LINK-A lncRNA overcomes ibrutinib resistance in mantle cell lymphoma by regulating Akt/Bcl2 pathway
Authors: Zhang Ye , Lu Peng , Zhou Yan , Zhang Lifei
Published: December 2021

Ibrutinib, a bruton tyrosine kinase (BTK) inhibitor which suppresses B-cell receptor signaling, has remarkably improved the outcome of patients with mantle cell lymphoma (MCL). However, approximately 33% of MCL patients have primary Ibrutinib resistance, and acquired Ibrutinib resistance is nearly universal. Long intergenic non-coding RNA for kinase activation (LINK-A) exerts oncogenic role in different types of tumors, but the role of LINK-A in intrinsic ibrutinib resistance in MCL is still unclear. Here, LINK-A expression level was first assessed using quantitative Real-time PCR (qPCR) and immunofluorescence analysis in five MCL cell lines. The effect of LINK-A on regulating MCL cells viability and apoptosis was assayed using CCK-8 and TdT-mediated dUTP nick end labeling (TUNEL) assay, respectively. The association of LINK-A with AKT activation and B cell lymphoma 2 (Bcl2)expression was evaluated using qPCR and western blot analysis. We found that LINK-A level was elevated in Ibrutinib-resistant MCL cell lines (Mino, REC-1, MAVER-1, and Granta-519) compared to Ibrutinib-sensitive MCL cell lines (Jeko-1). Functionally, LINK-A overexpression in Jeko-1 cells enhanced cell viability and repressed Ibrutinib-induced cell apoptosis. LINK-A knockdown in MAVER-1 cells decreased cell viability and further accelerated Ibrutinib-induced cell apoptosis. LINK-A overexpression enhanced Bcl2 expression in Jeko-1 cells, and Bcl2 inhibition blocked the effect of LINK-A on increasing cell viability in the presence of Ibrutinib. On the contrary, LINK-A knockdown reduced Bcl2 expression in MAVER-1 cells, and Bcl2 overexpression damaged the role of LINK-A inhibition in regulating cell viability. Mechanistically, LINK-A positively regulated the activation of AKT signaling, and inhibition of AKT signaling destroyed LINK-A-induced increased of Bcl2 and resulted in a subsequent suppression of cell viability. Taken together, the current results demonstrate that LINK-A inhibition overcomes Ibrutinib resistance in MCL cells by regulating AKT/Bcl2 pathway.
Characterizing the Type 6 Secretion System (T6SS) and its role in the virulence of avian pathogenic Escherichia coli strain APECO18
Authors: de Oliveira Aline L. , Barbieri Nicolle L. , Newman Darby M. , Young Meaghan M. , Nolan Lisa K. , Logue Catherine M.
Published: December 2021

Avian pathogenic E. coli is the causative agent of extra-intestinal infections in birds known as colibacillosis, which can manifest as localized or systemic infections. The disease affects all stages of poultry production, resulting in economic losses that occur due to morbidity, carcass condemnation and increased mortality of the birds. APEC strains have a diverse virulence trait repertoire, which includes virulence factors involved in adherence to and invasion of the host cells, serum resistance factors, and toxins. However, the pathogenesis of APEC infections remains to be fully elucidated. The Type 6 secretion (T6SS) system has recently gained attention due to its role in the infection process and protection of bacteria from host defenses in human and animal pathogens. Previous work has shown that T6SS components are involved in the adherence to and invasion of host cells, as well as in the formation of biofilm, and intramacrophage bacterial replication. Here, we analyzed the frequency of T6SS genes hcp, impK, evpB, vasK and icmF in a collection of APEC strains and their potential role in virulence-associated phenotypes of APECO18. The T6SS genes were found to be significantly more prevalent in APEC than in fecal E. coli isolates from healthy birds. Expression of T6SS genes was analyzed in culture media and upon contact with host cells. Mutants were generated for hcp, impK, evpB, and icmF and characterized for their impact on virulence-associated phenotypes, including adherence to and invasion of host model cells, and resistance to predation by Dictyostelium discoideum. Deletion of the aforementioned genes did not significantly affect adherence and invasion capabilities of APECO18. Deletion of hcp reduced resistance of APECO18 to predation by D. discoideum, suggesting that T6SS is involved in the virulence of APECO18.

Tendo em vista que o processo de representatividade e o fato destes corpos estarem em cena, atuando nas performances dançantes, proporciona e interliga discussões que nos permeiam diante das falas e das imagens a identificar a amplitude do Corpo Negro e questionar quais viés entre corpo, cor e estética podem decodificar a dança do Ballet.
Iron
Authors: Schenk Johannes
Published: December 2021

Iron is the most useful metal. It is the base element for steel, an iron‐based alloy, the most important metallic material in use. Iron production goes back to 1300 B.C., and the technologies were steadily further developed. The blast furnace is today the dominating process for converting iron ore to metallic iron. Alternative technologies are direct and smelting reduction processes. The production of iron is energy intensive and is today based on fossil energy. The production of iron for steelmaking is responsible for 6% of the global greenhouse gas emissions.
Flame‐Retardant Polymers
Authors: Stubbs Elizabeth , Chen Chien‐Han , Emrick Todd
Published: December 2021

The increasing use of inherently flammable polymers in society (ie, construction materials and transportation) presents a need to develop materials with flame‐retardant additives or inherently flame‐retardant polymers with low heat release properties. Developments in flammability testing techniques (eg, microscale combustion calorimetry) allow for efficient screening of novel materials and lend valuable insights into the flame‐retardant mechanisms of these materials. Effective halogenated molecules and polymers are widely used but have received increasing scrutiny for their environmental concerns. Thus, a breadth of research in recent years has spanned phosphorus‐based and fully hydrocarbon, inherently nonflammable molecules and polymers that provide promising solutions to this problem. In addition, organic/inorganic composites and coatings may be efficient flame‐retardant strategies, benefitting multiple properties including flame retardance, processing, and mechanics. Combining materials that provide low heat release properties with mechanistic insight will allow for the development of safe, low heat release materials.
Alkaline Oxygen Electrocatalysis for Fuel Cells and Metal–Air Batteries
Authors: Shah Syed S.A. , Najam Tayyaba , Brouzgou Angeliki , Tsiakaras Panagiotis
Published: December 2021

Currently, low‐carbon economy is getting importance and electrochemical energy conversion and storage technologies can play an important role in this development. Fuel cells and metal–air batteries are considered as emerging and potential alternate to conventional combustion engines. However, there are real problems that need to be faced, such as the cost, activity, and stability of electrode materials/electrocatalysts for energy conversion and storage. Recent progress in the materials design and synthesis showed that carbon‐based materials such as metal‐coordinated N‐doped carbons have better performance for oxygen electrocatalysis (OER, ORR) in both fuel cells and batteries. The active sites, an important feature of these catalysts, can be tuned by changing metallic centers, heteroatom‐doping (electronic structure, chemical composition), and porosity of materials derived from several precursors. By combining experimental results and theoretical calculations, facts revealed that the dispersion and chemical environment (elements coordinated with metal atom) in the active sites are significantly affected by the presynthesis and pyrolysis conditions. Therefore, MOF‐based precursors are considered as important due to their porosity and surface area.
The Direct Borohydride Fuel Cell

Published: December 2021

Fuel cells are clean power sources for both large‐scale and portable applications, as they provide a viable method for converting the chemical energy of fuel directly into electrical energy. The most developed FC is the H
2
‖O
2
system, which uses hydrogen as fuel. However, there are some issues with the use of hydrogen, such as sourcing, safety of handling, and storage. Direct borohydride fuel cells address some of these concerns. They consist of both fuel, which is oxidized at the anode, and hydrogen peroxide (or O
2
), which is reduced at the cathode. Their many advantages, such as high theoretical specific energy (up to 17 kWh kg
−1
) and high theoretical cell voltage (up to 3.02 V), have attracted increasing interest. Borohydride is also available in solid state (NaBH
4
) or as an aqueous electrolyte up to 30 wt%, where it remains with a half‐life of around 270 days at pH 13.9 (25 °C) in a strong alkaline solution. Borohydride FCs can operate under ambient conditions and in an air‐free environment, which makes them convenient for portable and anaerobic applications. The main challenge to their commercialization is the selectivity of the anode catalysts and their substrate materials. Many publications have investigated noble metals (e.g. platinum, gold, palladium) as candidate materials, but none have found yet an anode catalyst able to meet the needs of both high catalytic activity toward oxidation and low activity toward its hydrolysis. Several improving strategies are being investigated.

In this paper, we propose the design of a flexible one‐dimensional pressure‐sensing system that can localize deformation along a long strip and measure its magnitude with an integrated pair of sensors. The sensor system is fabricated with piezoresistive conductive foils and copper sheets encapsulated by adhesive tape with a total thickness of 0.7 mm. For the purpose of demonstration, the sensor is used to monitor the location and magnitude of kink deformation of an inflatable tube. Finite‐element modeling and simulation are conducted to investigate the behavior of the soft sensor system when subjected to kink deformation. The model‐predicted sensor output achieves good agreement with the experimental data for different deformation magnitudes. Finally, extensive experiments on a sensor prototype with dimensions of mounted on an inflatable tube are conducted to demonstrate the capability of the proposed scheme in simultaneous measurement of deformation location and magnitude. It is shown that the specific design approach minimizes the coupling of location and magnitude measurements, resulting in minimal complexity for data processing.

Semiconductors with very low lattice thermal conductivities are highly desired for applications relevant to thermal energy conversion and management, such as thermoelectrics and thermal barrier coatings. Although the crystal structure and chemical bonding are known to play vital roles in shaping heat transfer behavior, material design approaches of lowering lattice thermal conductivity using chemical bonding principles are uncommon. In this work, an effective strategy of weakening interatomic interactions and therefore suppressing lattice thermal conductivity based on chemical bonding principles is presented and a high‐efficiency approach of discovering low κL materials by screening the local coordination environments of crystalline compounds is developed. The resulting first‐principles calculations uncover 30 hitherto unexplored compounds with (ultra)low lattice thermal conductivities from 13 prototype crystal structures contained in the Inorganic Crystal Structure Database. Furthermore, an approach of rationally designing high‐performance thermoelectrics is demonstrated by additionally incorporating cations with stereochemically active lone‐pair electrons. These results not only provide atomic‐level insights into the physical origin of the low lattice thermal conductivity in a large family of copper/silver‐based compounds but also offer an efficient approach to discover and design materials with targeted thermal transport properties.

Mesoscale chiral materials are prepared by lithographic methods, assembly of chiral building blocks, and through syntheses in the presence of polarized light. Typically, these processes result in micrometer‐sized structures, require complex top–down manipulation, or rely on tedious asymmetric separation. Chemical vapor deposition (CVD) polymerization of chiral precursors into supported films of liquid crystals (LCs) are discovered to result in superhierarchical arrangements of enantiomorphically pure nanofibers. Depending on the molecular chirality of the 1‐hydroxyethyl [2.2]paracyclophane precursor, extended arrays of enantiomorphic nanohelices are formed from achiral nematic templates. Arrays of chiral nanohelices extend over hundreds of micrometers and consistently display enantiomorphic micropatterns. The pitch of individual nanohelices depends on the enantiomeric excess and the purity of the chiral precursor, consistent with the theoretical model of a doubly twisted LC director configuration. During CVD of chiral precursors into cholesteric LC films, aspects of molecular and mesoscale asymmetry combine constructively to form regularly twisted nanohelices. Enantiomorphic surfaces permit the tailoring of a wide range of functional properties, such as the asymmetric induction of weak chiral systems.

Whispering‐gallery mode (WGM) optical microcavity with enhanced evanescent field is one of the most perfect systems to study light–matter interaction. Unique sensing devices and potential applications with excellent performance can be expected by integrating smart particles into the microcavity, such as small mode volume and high sensitivity. Here, it is demonstrated that rolled‐up tubular optical microcavity decorated with palladium (Pd) nanoparticles (NPs) is capable for hydrogen (H2) sensing. Such microtube with subwavelength wall thickness exhibits enhanced sensing performance, e.g., detection limit of 1000 parts per million (ppm) and sensitivity in the order of 10−5 nm ppm−1, due to strong coupling in the evanescent field. Experiments and simulations are compared and guided the optimization for high figures of merit. The approach proves a unique route to couple smart particles with rolled‐up WGM microcavity for gas sensing, which have great application potentials in the field of nanophotonics and smart sensors.

Cup‐shaped molecules are of great interest due to their appealing architectures and properties. Compared with widely studied calixarenes, polyoxometalate‐based cup‐shaped molecules currently remain a virgin land waiting for exploration. In this work, we report the first discovery of two giant cup‐shaped inorganic–organic hybrid polyoxoniobates (PONbs) of {Cu12Nb120} and {Cd16Nb128}. The former integrates three tricyclic Nb24clusters and a hexacyclic Nb48cluster into a cup‐shaped molecule via a Cu12metallacalixarene, while the latter unifies two tricyclic Nb24clusters and a brand‐new pentacyclic Nb40cluster into another cup‐shaped molecule via a hybrid Cd16unit. With 132 and 144 metal centers, {Cu12Nb120} and {Cd16Nb128} show the largest two inorganic–organic hybrid PONbs known to date.

Novel methods to make synthetic chiral polymers are highly desirable given their potential in a rapidly increasing number of bio‐inspired applications. The enantiospecific sulfur–fluorine exchange (SuFEx) reaction of chiral di‐sulfonimidoyl fluorides (di‐SFs) with diphenols, was used to produce high‐molecular‐weight chiral polymers with configurational backbone chirality. The resulting new class of polymers, polysulfonimidates, can be efficiently produced via this step‐growth mechanism for a wide range of di‐SFs and diphenols, yielding MnPS up to 283 kDa with a typical dispersity Đ around 1.6. The optical activity of the resulting chiral polymers is largely due to the intrinsic asymmetry of the S atoms (configurational chirality). Finally, the enantiospecificity (ee>98 %) of the polymerization reaction was demonstrated by the degradation of a disulfide‐containing polysulfonimidate. This novel route towards configurational main‐chain chirality opens up new approaches towards tailor‐made chiral polymers with precisely defined properties.

Co‐processing biogenic feedstocks in oil refineries will reduce the greenhouse gas emissions normally associated with fossil‐derived transportation fuels. The fluid catalytic cracker (FCC) within a refinery is a robust processing unit and will probably be a preferred insertion point if biocrudes, produced by the liquefaction of biomass, are co‐processed within a refinery. Fluid catalytic cracking results in a wide range of intermediate products which can be upgraded to gasoline, diesel, heavy fuel oil and liquified petroleum gas blendstocks. Coke is also produced and provides heating for feedstocks, the endothermic catalytic cracking reactions and the regeneration of the FCC catalyst. However, coke combustion also generates carbon dioxide and is a significant source of refinery greenhouse gas emissions. As detailed here, the continuous nature of the process makes the physical evaluation of any biogenic coke fraction, via methods such as C14 isotope analysis, quite challenging. However, quantifying the stack gases provides one way of assessing the renewable content of the carbon dioxide derived from coke combustion. The hourly data from 1 year of commercial operation was assessed using linear and Bayesian ridge regression to quantify the burning coefficient of the coke when co‐processing lipids at the FCC. When a bootstrap method was used to reduce the uncertainties of the coefficients, this allowed us to quantify the renewable (green) fraction of the coke component, indicating the reduction in carbon dioxide emissions when commercially co‐processing biogenic feedstocks. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
