Authors: Reddy Varnika , Naidoo Rowena
Published: May 2018

BACKGROUND: Cardiovascular disease (CVD) is a rising burden in many parts of the world including South Africa. There is a strong relationship between CVD, type II diabetes and obesity. The CVD risk and health status of employees in tertiary institutions remains of high concern, as limited studies have been conducted in this area.OBJECTIVES: The study objectives were to determine the: CVD risk factor profile; possible risks of other NCDs; and lifestyle habits i.e. physical activity, nutritional/dietary habits, tobacco smoking and alcohol consumption of university employees.METHODS: A cross-sectional design was conducted on academic and non-academic (professional) staff members from the University of KwaZulu-Natal, South Africa. Purposive sampling of staff within the School of Health Sciences were selected to participate in this study. The data collection included health/fitness screening questionnaires, selected anthropometric measurements and non-fasting blood tests.RESULTS: Seventy-five staff members with a mean age of 39.71 years old voluntarily participated in this study. A significant number of staff members presented with a moderate CVD risk profile. Body fat percentages were significantly higher for females than for males. In addition waist circumference measures indicated possible risks for Type II diabetes and metabolic syndrome. The overall lifestyle habits were adequate to poor.CONCLUSION: There is an imperative need for workplace health interventions to improve CVD risk profiles and the susceptibility to other NCD’s among staff in tertiary institutions.

Assessment of the Content of Fluorescent Tracer in Granular Feed Mixture
Authors: Matuszek Dominika B , Wojtkiewicz Krystian
Published: May 2018

Background: This paper describes the use of fluorescence induced by UV radiation to evaluate the share of tracer in feed mixture. Methods: For the purpose of this study, three substances were used. They are as follows: Tinopal, Rhodamine B, and Uranine. Tracer in the form of maize or kardi was added to chicken feed before the mixing process. Grains used in the process were grinded in the mill sieve with a mesh size of 4 and 6 mm. The drawn samples of the mixture were illuminated with UV radiation to make grain tracer light, and then the photo was taken with a digital camera. The acquired images were analyzed with the use of a computer program running on the RGB color model, which was the way to obtain essential information about the percentage share of tracer. Results: It was observed that, in the case of kardi grains, the proposed method gives results significantly deviating from the verification method. Conclusions: Only the tests with the use of maize having an average particle diameter of 2.4 mm and tinted with the solution of Rhodamine B led to acceptable results (consensual with the predetermined verification level).

Authors: Zhang Haisheng , Xue Jing , Zhao Huanxia , Zhao Xinshuai , Xue Huanhuan , Sun Yuhan , Xue Wanrui
Published: May 2018

Background: The composition and sequence of amino acids have a prominent influence on the antioxidant activities of peptides. Objective: A series of isolation and purification experiments was conducted to explore the amino acid sequence of antioxidant peptides, which led to its antioxidation causes. Methods: The degreased apricot seed kernels were hydrolyzed by compound proteases of alkaline protease and flavor protease (3:2, u/u) to prepare apricot seed kernel hydrolysates (ASKH). ASKH were separated into ASKH-A and ASKH-B by dialysis bag. ASKH-B (MW < 3.5 kDa) was further separated into fractions by Sephadex G-25 and G-15 gel-filtration chromatography. Reversed-phase HPLC (RP-HPLC) was performed to separate fraction B4b into two antioxidant peptides (peptide B4b-4 and B4b-6). Results: The amino acid sequences were Val-Leu-Tyr-Ile-Trp and Ser-Val-Pro-Tyr-Glu, respectively. Conclusions: The results suggested that ASKH antioxidant peptides may have potential utility as healthy ingredients and as food preservatives due to their antioxidant activity. Highlights: Materials with regional characteristics were selected to explore, and hydrolysates were identified by RP-HPLC and matrix-assisted laser desorption ionization-time-of-flight-MS to obtain amino acid sequences.
Development of Lateral Flow Immunochromatographic Strips for Micropollutants Screening Using Colorants of Aptamer Functionalized Nanogold Particles Part I Methodology and Optimization
Authors: Zhao Shuai , Zhang Shan , Wang Sai , Liu Jiahui , Dong Yiyang
Published: May 2018

A methodology of lateral flow immunochromatographic strip based on aptamer was developed for on-site detection of the small molecule micropollutants. In the present study, we try for the first time to investigate the feasibility of developing a strip assay for the analysis of micropollutants as methodological prototypes by combining the high selectivity and affinity of aptamers with the unique optical properties of nanogolds. This quantitative method was based on the competition for the aptamer between targets and DNA probes. Crucial parameters that might influence the sensitivity, such as the size of nanogolds, amount of aptamer, type and pH of streptavidin, type of nitrocellulose (NC) membrane, blocking procedure, and reading time, were systematically investigated to obtain the optimum assay performance. With the optimized conditions [nanogolds 25 nm, 50 μM aptamer, pH 8 of GSA (a type of streptavidin named “SA Gold,” which is a sulfhydrylization streptavidin), Millipore HFC 135 NC membrane, 1% bovine serum albumin as the blocking agent and added in the running buffer and sample pad soakage agents, and 20 min reading time] the aptamer-based lateral flow assay will show a low visual limit of detection and scanning reader LOD. The strip for on-site screening using colorants of aptamer functionalized nanogold particles did not require any complicated equipment and was a potential portable tool for rapid identification of micropollutants.
Utopie et dystopie
Authors: Kemp Peter ,   Philosophy Documentation Center
Published: May 2018

This paper tries to show that, in our criticism of society today, it is not enough to presuppose an idea of utopia but also to integrate an idea of dystopia into our reflections. The first two parts consider two documents that analyze the socio- environmental crisis of our world today: (1) the fifth assessment report published by the Intergovernmental Panel on Climate Change in 2014, and (2) the Encyclical Letter of Pope Francis on Care of Our Common Home, which argues that there are not two different crises but one single socio-environmental crisis that threatens all life on our planet, and calls for a new ethics. The next two parts confront two philosophers, Ernst Bloch and Hans Jonas. Bloch has provided a strong defense of the utopian thinking but in a Marxist context, whereas Jonas has rejected all utopian thinking and replaced it with the idea of responsibility for the present world. Both thinkers need a more fundamental idea of hope.
Justice in the Prophetic Tradition
Authors: Svenungsson Jayne ,   Philosophy Documentation Center
Published: May 2018

This paper explores the idea of justice in the prophetic strand of the Jewish and Christian traditions. First, a brief description is given of the context in which the prophetic idea of justice first evolves. Second, focussing on the historical and prophetic literature Hebrew Bible, an analysis of the defining characteristics of this idea of justice is undertaken. Third and finally, the relevance of this prophetic tradition for our contemporary politico-philosophical debates on justice is discussed in relation to the discourse on law and justice initiated by Jacques Derrida in the 1990s and followed up by Giorgio Agamben during the last decades.
Just Persons
Authors: McCormick Peter ,   Philosophy Documentation Center
Published: May 2018

Ethics has to do basically with what and who acting persons are. Persons however act variously. Some persons are basically individualists. They characteristically act as if they are as wholly independent as possible from other persons. Other persons are collectivists. They act as if they are as much a dependent part of some larger community of persons as possible. - Accordingly, one cardinal issue for any philosophical ethics like eco-ethics is whether almost all persons are, fundamentally, independent entities. That is, are almost all persons independent entities, or are almost all persons dependent ones? - The idea I try to pursue here briefly is that, fundamentally, persons are neither independent nor dependent entities but interdependent ones. They are so in the senses of not being essentially prior to, or ontologically more basic than, or having their ontological identity apart from other persons.

Picture this: all of a liaison librarian’s students and faculty in one place, telling stories about how the library and its resources have been integral to their work, learning about resources and services they never knew about, and inspiring one another with their work and their own unique methods of working with the library. It sounds like an amazing dream, right? Two arts librarians at the University of California-Irvine (UCI) were able to turn their dreams into reality in October 2016, when they worked together to throw an epic library open house for their liaison areas.
Rethinking Child Protection in Emergencies
Authors: Bennouna Cyril , Fischer Hanna-Tina , Wessells Michael , Boothby Neil
Published: May 2018

The humanitarian system is struggling to adapt to changes in the global political environment, trends in armed conflict and displacement, and advances in science and technology. In recent years, the international community has undertaken a number of efforts to overcome these challenges, such as the Agenda for Humanity, a plan that outlines the changes needed to alleviate suffering, reduce risk, and lessen vulnerability on a global scale. This article reviews recent evidence from a range of disciplines to inform these efforts, especially as they relate to the protection of children. Early childhood and adolescence constitute two critical periods of child development that lay the foundations for future health and wellbeing. Exposure to adversity in crisis contexts can compromise this development, with potentially life-long consequences. Evidence suggests that relationships with caregivers and peers play a central role in mediating childhood experiences of adversity. Unfortunately, interventions for children affected by crises are usually too fragmented to maximize the protective effects of healthy relationships. This article stresses the importance of developing multisectoral and relational interventions capable of promoting healthy development across the life course. Given the central role of caregivers, the household is an especially powerful level of intervention for combining approaches from different sectors. More concerted efforts are needed to develop household interventions that combine traditional sectoral approaches with innovative, cross-cutting measures, such as cash transfers and parental support. Household interventions should also be an integral part of broader community and society level actions, which together form more comprehensive systems of care.
Project Spraoi: Dietary Intake, Nutritional Knowledge, Cardiorespiratory Fitness and Health Markers of Irish Primary School Children
Authors: Merrotsy A. , McCarthy A.L. , Flack J. , Lacey S. , Coppinger T
Published: May 2018

Objective: Examine dietary intake (DI), anthropometric measures, cardiorespiratory fitness (CRF) and nutritional knowledge (NK) of school children.
Design: Cross-sectional study. Food Diary, NK questionnaire and 550m walk/run test were used to assess DI, NK and CRF respectively. Blood pressure (BP) was also taken and body mass index (BMI) and waist to height ratio (WHtR) were calculated.
Setting: Two primary schools, Cork, Ireland.
Subjects: Six (n = 49, age 5.9 ± 0.6 years) and ten (n = 52, age 9.8 ± 0.5 years) year olds.
Results: Intakes of fruit and vegetables, fibre, calcium and iron were sub-optimal. Unhealthy snacks and saturated fat intakes were higher than recommended. A total of 24.4% of six year olds and 35.4% of ten year olds were classified as ‘fast’. Furthermore, 45.9% of six and ten year olds had high-normal BP and 27.9% had high BP. NK was negatively correlated with sugar intake (r = -0.321, p = 0.044) in ten year olds. WHtR was negatively correlated with servings of vegetables in six year olds (r = -0.377, p = 0.014). For ten year olds, there was a positive correlation between WHtR and run score (r = 0.350, p = 0.014) and BMI and run score (r = 0.482, p = 0.001).
Conclusion: This study highlights, for the first time, DI, NK, CRF, BP and anthropometric data for Irish children and their potential combined effect on overall health. Study results suggest preventive initiatives are needed, in children as young as 6 years of age.
The effects of feedback from horse welfare assessments
Authors: Viksten SM , Visser EK , Hitchens PL , Blokhuis HJ
Published: May 2018

This study was designed to determine whether feedback from welfare assessments, using the Horse Welfare Assessment Protocol, affected actual horse welfare in 21 stables. After the first assessment, stable managers in the high feedback (HF; n = 10 stables) group were supplied with extensive information and support regarding the welfare measures and relevance of the results. The low feedback (LF; n = 11 stables) group only received the results without additional information. Upon re-assessment, six months later, no significant changes were seen in the stable overall (SO) score in either group. Significant changes occurred in individual measures; in the HF group more fresh-air inlets were open but water drinker function and ocular discharge deteriorated. In the LF group, the feeding troughs were cleaner but mane and tail condition deteriorated. Both groups had cleaner water troughs and less equipment chafing but the sum of relative air humidity (RH) and temperature (T) deteriorated. Significant decreases occurred in the stable welfare issues (SWI) score; the HF group decreased from 93.3 to 72.0 and the LF group from 113.3 to 91.3. There were also nonsignificant changes; in the HF group, 71 measures and five stables improved while 63 measures and five stables (50%) deteriorated. In the LF group, 65 measures and seven stables improved while 62 measures and four stables deteriorated. The observed improvements in both groups suggest that assessment alone (with no detailed feedback) might raise awareness but we cannot yet conclude whether or not the type of feedback affects overall horse welfare.
Impact of personal values and personality on motivational factors for farmers to work with farm animal welfare: a case of Swedish dairy farmers
Authors: Hansson H , Lagerkvist CJ , Vesala KM
Published: May 2018

In this study, we sought to explain why dairy farmers give importance to various use and non-use values of animal welfare. In particular, we examined how the farmers could be segmented according to the relative importance they give to various use and non-use values in animal welfare and whether this segmentation could be explained by farmers’ personal values and personality traits. Based on a latent class analysis using best-worst scaling data on 123 Swedish dairy farmers, three segments of farmers were found: animalcentred, human-centred and business-orientated. These groups were related to measures of farmers’ personal values and personality traits in a point-biserial correlation and a hierarchal multinomial logistic regression analysis. The results suggest that the segmentation is related to personal values, but not to personality traits. This finding is important from a policy perspective, because the existence of different segments of farmers who are motivated by different values in animal welfare indicates a need to approach different farmers in different ways if policy is to succeed in improving animal welfare. It also indicates a possibility to influence the segments to improve animal welfare by measures that are sensitive to value dynamics of the farmers.
Hors chant. Arrangements godardiens pour violoncelle et cordes élargies
Authors: Faucon Térésa
Published: May 2018

Dans les compositions musicales de ses films, Jean-Luc Godard nous fait entendre son écoute d’oeuvres musicales, invente des arrangements avec les moyens du cinéma qui pourraient porter une double signature, Beethoven-Godard, Dvořák-Godard, comme les arrangements des musiciens Beethoven-Liszt ou Bach-Webern. Pour cette étude, nous avons choisi de nous concentrer sur les oeuvres pour violoncelle, instrument pour lequel Godard semble avoir une prédilection comme pour les cordes frottées en général pour la plasticité de la matière sonore. Nous analysons l’arrangement du Concerto pour violoncelle et orchestre en si mineur, op. 104 d’Antonin Dvořák(1895) dans Je vous salue, Marie (1983) puis la conversation entre deux compositeurs et interprètes, Godard au banc montage et David Darling, avec son violoncelle à huit cordes et les oeuvres originales créés pour le cinéaste.
L’invention musicale face à la nature dans Grizzly Man, The Wild Blue Yonder et La grotte des rêves perdus de Werner Herzog
Authors: Deville Vincent
Published: May 2018

Quand le cinéaste allemand Werner Herzog réalise ou produit trois documentaires sur la création et l’enregistrement de la musique de trois de ses films entre 2005 et 2011, il effectue un double geste de révélation et d’incarnation : les notes nous deviennent visibles à travers le corps des musiciens. Ce faisant, Herzog nous délivre son art poétique : les formes musicales répondent à la nature, si présente dans ses films ; la nature est envisagée comme un instrument d’accord tandis que la musique devient une puissance d’estrangement, de désaccord de nos perceptions ; et en nous donnant accès aussi bien à un infigurable – l’être moral – qu’au corps matériel fait de chair et d’os, la musique nous ouvre la voie qui mène au coeur du monde.
Candidate genes in gastric cancer identified by constructing a weighted gene co-expression network
Authors: Chen Jian , Wang Xiuwen , Hu Bing , He Yifu , Qian Xiaojun , Wang Wei
Published: May 2018

Background

Gastric cancer (GC) is one of the most common cancers with high mortality globally. However, the molecular mechanisms of GC are unclear, and the prognosis of GC is poor. Therefore, it is important to explore the underlying mechanisms and screen for novel prognostic markers and treatment targets.

Methods

The genetic and clinical data of GC patients in The Cancer Genome Atlas (TCGA) was analyzed by weighted gene co-expression network analysis (WGCNA). Modules with clinical significance and preservation were distinguished, and gene ontology and pathway enrichment analysis were performed. Hub genes of these modules were validated in the TCGA dataset and another independent dataset from the Gene Expression Omnibus (GEO) database by t-test. Furthermore, the significance of these genes was confirmed via survival analysis.

Results

We found a preserved module consisting of 506 genes was associated with clinical traits including pathologic T stage and histologic grade. PDGFRB, COL8A1, EFEMP2, FBN1, EMILIN1, FSTL1 and KIRREL were identified as candidate genes in the module. Their expression levels were correlated with pathologic T stage and histologic grade, also affected overall survival of GC patients.

Conclusion

These candidate genes may be involved in proliferation and differentiation of GC cells. They may serve as novel prognostic markers and treatment targets. Moreover, most of them were first reported in GC and deserved further research.
The pitfalls of short-range endemism: high vulnerability to ecological and landscape traps
Authors: Mason Leanda D. , Bateman Philip W. , Wardell-Johnson Grant W.
Published: May 2018

Ecological traps attract biota to low-quality habitats. Landscape traps are zones caught in a vortex of spiralling degradation. Here, we demonstrate how short-range endemic (SRE) traits may make such taxa vulnerable to ecological and landscape traps. Three SRE species of mygalomorph spider were used in this study: Idiommata blackwalli, Idiosoma sigillatum and an undescribed Aganippe sp. Mygalomorphs can be long-lived (>43 years) and select sites for permanent burrows in their early dispersal phase. Spiderlings from two species, I. blackwalli (n = 20) and Aganippe sp. (n = 50), demonstrated choice for microhabitats under experimental conditions, that correspond to where adults typically occur in situ. An invasive veldt grass microhabitat was selected almost exclusively by spiderlings of I. sigillatum. At present, habitat dominated by veldt grass in Perth, Western Australia, has lower prey diversity and abundance than undisturbed habitats and therefore may act as an ecological trap for this species. Furthermore, as a homogenising force, veldt grass can spread to form a landscape trap in naturally heterogeneous ecosystems. Selection of specialised microhabitats of SREs may explain high extinction rates in old, stable landscapes undergoing (human-induced) rapid change.

Published: May 2018

Este artigo aborda uma prática social mediada por uma rede social virtual de viajantes denominada Couchsurfing. Traduzida como “surfe de sofá”, essa prática é conhecida pela oferta gratuita de hospedagem, mundialmente, viabilizando a interação online e offline entre os sujeitos cadastrados, além de promover o câmbio de hospitalidade, em que anfitrião vira hóspede em outras situações de viagem e vice-versa. Nesta pesquisa, foram investigados os anfitriões e hóspedes do município de Jaguarão, localizado no extremo sul do estado do Rio Grande do Sul (RS), Brasil. Os objetivos do artigo são identificar e discutir os principais interesses e motivações pela rede e pelas viagens Couchsurfing, entre os anfitriões e hóspedes jaguarenses, bem como compreender o sistema de trocas entre hóspedes e anfitriões tendo como inspiração os estudos da hospitalidade baseados na Teoria da Dádiva, de Marcel Mauss. A investigação teve abordagem qualitativa e aproximou-se do método netnográfico. O percurso metodológico contou com estudo bibliográfico e pesquisa de campo ciberespacial, com entrevistas semiestruturadas e observações. As trocas se dão de maneira online e offline, em diferentes prismas. A pesquisa apresenta novos desafios para os estudos do turismo, lazer e hospitalidade no contexto de práticas sociais emergentes, como o Couchsurfing.

A ESTADUALIZAÇÃO DO PROGRAMA CULTURA VIVA
Authors: Rocha Sophia Cardoso
Published: May 2018

O Ministério da Cultura (MinC) vem empreendendo esforços para fortalecer o pacto federativo brasileiro por meio da descentralização de suas políticas. Nesse sentido, este artigo analisa a experiência da estadualização do Programa Cultura Viva/Projeto Ponto de Cultura no Estado da Bahia. Tal estudo revela que o MinC adotou como modelo de descentralização a reprodução de programas e projetos de sua própria autoria; verifica que o Programa Cultura Viva, ainda que marcado por uma série de problemas, foi o principal eixo de ação do Programa Mais Cultura, que promoveu a sua expansão; aponta que a estadualização do Projeto Ponto de Cultura não resolveu as dificuldades enfrentadas em âmbito federal, e sim as replicou; e por fim, destaca questões a serem discutidas na perspectiva da consolidação do Sistema Nacional de Cultura (SNC).

Most attempts to emulate the mechanical properties of strong and tough natural composites using helicoidal films of wood‐derived cellulose nanocrystals (w‐CNCs) fall short in mechanical performance due to the limited shear transfer ability between the w‐CNCs. This shortcoming is ascribed to the small w‐CNC‐w‐CNC overlap lengths that lower the shear transfer efficiency. Herein, we present a simple strategy to fabricate superior helicoidal CNC films with mechanical properties that rival those of the best natural materials and are some of the best reported for photonic CNC materials thus far. Assembling the short w‐CNCs with a minority fraction of high aspect ratio CNCs derived from tunicates (t‐CNCs), we report remarkable simultaneous enhancement of all in‐plane mechanical properties and out‐of‐plane flexibility. The important role of t‐CNCs is revealed by coarse grained molecular dynamics simulations where the property enhancement are due to increased interaction lengths and the activation of additional toughening mechanisms. At t‐CNC contents greater than 5% by mass the mixed films also display UV reflecting behaviour. These damage tolerant optically active materials hold great promise for application as protective coatings. More broadly, we expect the strategy of using length‐bidispersity to be adaptable to mechanically enhancing other matrix‐free nanoparticle ensembles.

The colors of photonic crystals are based on their periodic crystalline structure. They show clear advantages over conventional chromophores for many applications, mainly due to their anti‐photobleaching and responsiveness to stimuli. More specifically, combining colloidal photonic crystals and invisible patterns is important in steganography and watermarking for anticounterfeiting applications. Here a convenient way to imprint robust invisible patterns in colloidal crystals of hollow silica spheres is presented. While these patterns remain invisible under static environmental humidity, even up to near 100% relative humidity, they are unveiled immediately (≈100 ms) and fully reversibly by dynamic humid flow, e.g., human breath. They reveal themselves due to the extreme wettability of the patterned (etched) regions, as confirmed by contact angle measurements. The liquid surface tension threshold to induce wetting (revealing the imprinted invisible images) is evaluated by thermodynamic predictions and subsequently verified by exposure to various vapors with different surface tension. The color of the patterned regions is furthermore independently tuned by vapors with different refractive indices. Such a system can play a key role in applications such as anticounterfeiting, identification, and vapor sensing.
Topological Adhesion of Wet Materials

Achieving strong adhesion between wet materials (i.e., tissues and hydrogels) is challenging. Existing adhesives are weak, toxic, incompatible with wet and soft surfaces, or restricted to specific functional groups from the wet materials. The approach reported here uses biocompatible polymer chains to achieve strong adhesion and retain softness, but requires no functional groups from the wet materials. In response to a trigger, the polymer chains form a network, in topological entanglement with the two polymer networks of the wet materials, stitching them together like a suture at the molecular scale. To illustrate topological adhesion, pH is used as a trigger. The stitching polymers are soluble in water in one pH range but form a polymer network in another pH range. Several stitching polymers are selected to create strong adhesion between hydrogels in full range of pH, as well as between hydrogels and various porcine tissues (liver, heart, artery, skin, and stomach). The adhesion energy above 1000 J m−2is achieved when the stitching polymer network elicits the hysteresis in the wet materials. The molecular suture can be designed to be permanent, transient, or removable on‐demand. The topological adhesion may open many opportunities in complex and diverse environments.

The (LaV3+O3)m/SrV4+O3 (m = 5, 6) superlattices are investigated by first principles calculations. While bulk LaVO3 is a C‐type antiferromagnetic semiconductor and bulk SrVO3 is a paramagnetic metal, semiconducting A‐type antiferromagnetic states for both superlattices are found due to epitaxial strain. At the interfaces, however, the V spins couple antiferromagnetically for m = 5 and ferromagnetically for m = 6 (m‐dependence of the magnetization). Electronic reconstruction in form of charge ordering is predicted to occur with V3+ and V4+ states arranged in a checkerboard pattern on both sides of the SrO layer. As compared to bulk LaVO3, the presence of V4+ ions introduces in‐gap states that strongly reduce the bandgap and influence the orbital occupation and ordering.

A novel manufacturing approach to fabricate liquid metal‐based, multifunctional microcapillary pipettes able to provide electrodes with high electrical conductivity for high‐frequency electrical stimulation and measurement is proposed. 4D single cell manipulation is realized by applying multifrequency, multiamplitude, and multiphase electrical signals to the microelectrodes near the pipette tip to create 3D dielectrophoretic trap and 1D electrorotation, simultaneously. Functions such as single cell trapping, patterning, transfer, and rotation are accomplished. Cell viability and multiday proliferation characterization has confirmed the biocompatibility of this approach. This is a simple, low‐cost, and fast fabrication process that requires no cleanroom and photolithography step to manufacture 3D microelectrodes and microchannels for easy access to a wide user base for broad applications.

2D Dirac materials supported by nonmetallic substrates are of particular interest due to their significance for the realization of the quantum spin Hall effect and their application in field‐effect transistors. Here, monolayer germanene is successfully fabricated on semiconducting germanium film with the support of a Ag(111) substrate. Its linear‐like energy–momentum dispersion and large Fermi velocity are derived from the pronounced quasiparticle interference patterns in a √3 × √3 superstructure. In addition to Dirac fermion characteristics, the theoretical simulations reveal that the energy gap opens at the Brillouin zone center of the √3 × √3 restructured germanene, which is evoked by the symmetry‐breaking perturbation potential. These results demonstrate that the germanium nanosheets with √3 × √3 germanene can be an ideal platform for fundamental research and for the realization of high‐speed and low‐energy‐consumption field‐effect transistors.

For the first time, a 3D Prussian blue analogue (PBA) with well‐defined spatial organization is fabricated by using a nickel hydroxide array as a precursor. The nickel hydroxide arrays are synthesized in titanium foil and reacted with K3[Fe(CN)6]. The plate‐like morphology of the nickel hydroxide is perfectly preserved and combined with abundant PBA nanocubes. After phosphidation at 350 °C, the obtained sample demonstrated excellent hydrogen evolution reaction (HER) activity in both acid and alkaline solutions to reach a current density of 10 mA cm−2 with an overpotential of only 70 and 121 mV, respectively. With an overpotential of 266 mV, it can reach a larger current density of 500 mA cm−2 in acid. The efficient HER activity of the obtained sample is mainly ascribed to its structural advantage with various active metal sites derived from the nickel hydroxide and PBA precursor. In addition, long‐term stability measurements have verified the good performance of the obtained sample in acid and alkaline solutions. An increment of overpotential of only 8 and 9 mV is observed, in the acid and alkaline solutions respectively. Beyond these assets, it is supposed that the strategy to synthesize 3D PBA arrays from nickel hydroxide can be extended to other metal–organic frameworks arrays for more electrochemical applications.

Efficient and selective dehydrogenation of hydrazine borane (HB), a novel hydrogen storage material with very high hydrogen content (HB, 15.4 wt%), is a key challenge for a fuel‐cell‐based hydrogen economy. However, even using the noble metal catalysts for HB decomposition, the activities are still far from satisfying, to say nothing of non‐noble‐metal‐containing catalysts. In response, as a proof‐of‐concept experiment, herein, noble‐metal‐free NiFe–CeOx nanoparticles are successfully immobilized on an MIL‐101 support without surfactant by a simple liquid impregnation method. Unexpectedly, the resultant Ni0.5Fe0.5–CeOx/MIL‐101 catalyst shows good performance, including 100% H2 selectivity, 100% conversion, and record catalytic activity (351.3 h−1) for hydrogen generation at mild temperature, which is even better than most of the noble metal heterogeneous catalysts and might be attributed to the good dispersion and uniform particle size of the Ni0.5Fe0.5–CeOx nanoparticles due to steric restrictions effect of the MIL‐101 support. Additionally, extending MIL‐101 to some other important kinds of metal–organic framework (MOF) structures, the resultant NiFe–CeOx/MOF catalysts all show good catalytic activity toward HB decomposition, showing the universality of the MOF supported NiFe–CeOx catalysts.
