Materials Science at the Swiss Light Source
Authors: Patterson Bruce D. , Abela Rafael , Van der Veen J. Friso
Published: May 2022

This article describes a state-of-the-art hard X-ray beamline for materials science at a third-generation synchrotron light source presently being commissioned in Switzerland, together with two typical pieces of experimental work for which the beamline is being optimized. After a discussion
of the motivation, photon source, optics and experimental stations of the beam line, we present the results of some X-ray scattering studies of order–disorder phenomena that were recently performed at other synchrotron radiation sources (HASYLAB, Hamburg, and ESRF, Grenoble). The phenomena
to be discussed are spontaneous ordering in epitaxial AlxGa1-xAs films and confinement-induced ordering of colloidal solutions.

Published: May 2022

The extension of crystallographic methods to minerals at non-ambient conditions and materials of technical interest is of importance for understanding the mutual relationship between crystal structure and physico-chemical properties. We apply this approach to understand the physics
of the interior of the Earth as well as to contribute to the search for efficient non-linear optical materials.
New Physical Methods for a Space Resolved Mapping of the Macroscopic Polarisation in Molecular Crystals and a Stochastic Theory for Understanding
Authors: Hulliger Jürg
Published: May 2022

The spatial distribution of polarity in molecular crystals built up by dipolar entities was imaged by two new techniques: Scanning pyroelectric microscopy (SPEM) and phase-sensitive second harmonic microscopy (PS-SHM). SPEM maps the variation in electrical polarisation due to a change
in temperature (pyroelectric effect). The PS-SHM contrast is caused by a change of the sign of the molecular hyperpolarisability (nonlinear optical effect). A spatial inhomogeneity of polar properties in molecular crystals is predicted by a 2D Ising-type model describing 180° orientational
disorder at the crystal-nutrient interface. As a result of (slow) growth, centric and acentric seed crystals can continuously transform into bipolar (twinned) crystals showing an inhomogeneous spatial distribution of polarity in the as-grown state.

Authors: Maienza Francesca , Spindler Felix , Thommen Marc , Pugin Benoît , Mezzetti Antonio
Published: May 2022

The synthesis of P-stereogenic ligands bearing 2,6-disubstituted phenyl groups at the P atom is a challenging problem. The results reported herein help define the scope and limitations of the existing synthetic protocols, such as Jugé's oxazaphospholidine borane method and the enantioselective deprotonation of P(BH3)(CH3)2(R) developed by Evans and Imamoto. Jugé's new approach based on chlorophosphine boranes was exploited for the preparation of a C1-symmetric MiniPhos-like ligand. Preliminary results concerning the application of the new ligands in the rhodium and ruthenium hydrogenation of olefins are also reported.

Recent Developments in Asymmetric Catalysis
Authors: Pfaltz Andreas
Published: May 2022

Asymmetric catalysis has long been dominated by C2-symmetric bidentate ligands. More recently, sterically and electronically unsymmetrical ligands have found increasing attention. An important family of these are the phosphinooxazoline (PHOX) ligands incorporating one P-coordinating and one N-coordinating unit. Important applications of PHOX ligands include Pd-catalyzed allylic substitution and Ir-catalyzed hydrogenation.
Fabrication of Naphthalimide Chemosensor by Inkjet Printing on Paper for the Detection of Uric Acid in Solution
Authors: Karalkar Vedant , Akinyode Adenike , Abraham Clay , Alford Jane
Published: May 2022

High uric acid (UA) concentrations are linked to many human health disorders. Currently, UA is detected in human samples through laboratory testing. However, laboratory testing is impractical in developing nations, which lack the diagnostic capability (trained professionals, complex laboratory equipment, and analytical instruments) necessary for this approach. The lack of resources leads to the spread of chronic illnesses in these countries. To combat this issue, a paper test strip is proposed that provides a measure of UA in a point-of-care setting without requiring the use of expensive instruments or qualified professionals. The rapid detection of UA in solution was achieved by a naphthalimide-based “turn-on” chemosensor. Divinyl sulfone was used to immobilize the chemosensor onto cellulose paper. A colorimetric detection technique was created that took advantage of photoinduced electron transfer (PET) technology, which allowed for the creation of a sensor whose fluorescence was directly proportional to the UA concentration. To interpret the results from the paper strips, a calibration curve was created that determined the concentration of UA in the solutions. The test strip was used to determine UA concentration in synthetic urine and grain samples. The results from the calibration curve show that UA concentration in the grain samples is within the range of the calibration curve, while it is slightly lower in the case of UA in synthetic urine due to possible quenching of the probe in urine.
Cross-Metathesis approach to a,w-Bifunctional Compounds from Methyl Oleate and cis-2-Butene-1,4-diol
Authors: Mudiyanselage Ajith , Viamajala Sridhar , Varanasi Sasidhar , Yamamoto Kana
Published: May 2022

The cross metathesis (CM) of methyl oleate (1) and cis-2-butene-1,2-diol (2) was investigated to access alpha, omega-bifunctional compounds. The optimal CM conditions involve Stewart-Grubbs catalyst at 0 °C, delivering CM product 3 in excellent yield. 3 was converted, in a single step and in >90% yields, to alcohol 7, aldehyde 8, and olefin 10, the useful synthetic intermediates for many specialty chemicals, including PA11 precursor. A tandem CM/isomerization process was also demonstrated for the first time.
A Robust and Efficient Propane Dehydrogenation Catalyst from Unexpectedly Segregated Pt2Mn Nanoparticles
Authors: Rochlitz Lukas , Pessemesse Quentin , Fischer Jörg W. A. , Klose Daniel , Clark Adam H. , Plodinec Milivoj , Jeschke Gunnar , Payard Pierre-Adrien , Copéret Christophe
Published: May 2022

The increasing demand for short chain olefins like propene for plastics production and the availability of shale gas make the development of highly performing propane dehydrogenation (PDH) catalysts, robust towards industrially applied harsh regeneration conditions, a highly important field of research. A combination of surface organometallic chemistry (SOMC) and thermolytic molecular precursor (TMP) approach was used to prepare a nanometric, bimetallic Pt-Mn material (3 wt% Pt, 1.3 wt% Mn) supported on silica via consecutive grafting of a Mn and Pt precursor on surface OH groups present on the support surface, followed by a treatment under a H2 flow at high temperature. The material exhibits a 70 % fraction of the overall Mn as MnII single sites on the support surface; the remaining Mn is incorporated in segregated Pt2Mn nanoparticles. The material shows great performance in PDH reaction with a low deactivation rate. In particular, it shows outstanding ro-bustness during repeated regeneration cycles, with conversion and selectivity stabilizing at ca. 37 % and 98 %, respectively. Notably, a material with a lower Pt loading of only 0.05 wt% shows an outstanding catalytic performance – initial produc-tivity of 4523 gC3H6/gPt h and an extremely low kd of 0.003 h-1 under a partial pressure of H2 – ranging among the highest reported productivities. A combined in situ XAS, STEM, EPR and metadynamics at the DFT level study could show that the strong interaction between the MnII decorated support and the unexpectedly segregated Pt2Mn particles is most likely re-sponsible for the outstanding performance of the investigated materials.
Bond Bundle Analysis of Ketosteroid Isomerase
Authors: Wilson Timothy , Morgenstern Amanda , Alexandrova Anastassia , Eberhart Mark
Published: May 2022

Bond bundle analysis is used to investigate enzymatic catalysis in the ketosteroid isomerase (KSI) active site. We identify the unique bonding regions in five KSI systems, including those exposed to applied oriented electric fields and those with amino acid mutations, and calculate the precise redistribution of electron density that accompanies either enhancement or inhibition of KSI catalytic activity. In two examples—using direct inspection of bond bundle regional properties, and using correlations between those properties and reaction barrier height—we arrive at similar conclusions, that catalytic enhancement results from promoting electron density redistribution between bonds within the KSI-docked substrate molecule in a way that closely resembles our mechanistic understanding of the forward catalyzed reaction. The catalyzing charge redistribution between bond bundles is prevalent in KSI systems catalyzed via electric fields or via amino acid mutation, and are thus suggestive of a general catalytic role.
Neumann’s Principle Based Eigenvector Approach for Deriving Non-Vanishing Tensor Elements for Nonlinear Optics
Authors: Wu Zishan , Xiong Wei
Published: May 2022

Physical properties are commonly represented by tensors, such as optical susceptibilities. Conventional approach of deriving non-vanishing tensor elements of symmetric systems relies on the intuitive consideration of positive/negative sign flipping after symmetry operations, which could be tedious and prone to miscalculation. Here we present a matrix-based approach which gives a physical picture centered on Neumann’s principle. The principle states that symmetries in geometric systems are adopted by their physical properties. We mathematically apply the principle to the tensor expressions and show a clear mathematical procedure to derive non-vanishing tensor elements based on eigensystems. Examples on commonly known 2nd and 3rd-order nonlinear susceptibilities are shown, together with complicated scenarios involving uncommon symmetries such as C7 and octahedral symmetries, as well as higher-rank tensors such as 5th-order nonlinear signals. This generalized approach can be applied to any symmetry and higher order nonlinear processes, useful for developing and understanding higher order nonlinear optical signals.
Robotic cell assembly to accelerate battery research
Authors: Zhang Bojing , Fischer Leon , Sanin Alexey , Stein Helge Sören
Published: May 2022

Manual cell assembly confounds with research digitalization and reproducibility. Both are however needed for data-driven optimization of cell chemistries and charging protocols. Therefore, we present herein an automatic battery assembly system (AutoBASS) that is capable of assembling batches of up to 64 CR2023 cells. AutoBASS allows us to acquire large datasets on in-house developed chemistries and is herein demonstrated with NMC811 and Si@Graphite electrodes with a focus on formation and manufacturing data. The large dataset enables us to gain insights into the formation process through dQ/dV analysis and assess cell to cell variability. Exact robotic electrode placement provides a baseline for laboratory-scale manufacturing and reproducibility towards the accelerated translation of findings from the laboratory to the pilot plant scale.

Estudio de impacto ambiental
Authors: Márquez Robles José
Published: May 2022

En setiembre de 1990, después de vivir muchos años de espaldas a la polución ambiental, el país se impulso al control del medio ambiente al darse los dispositivos legales pertinentes a través del Decreto Leg. N° 611, que regula el uso del ambiente y fabricación de materiales contaminantes asi como su deliberada evacuación hacia el medio ambiente y sanciona a través de la ley las infracciones que conllevan contaminación del mismo.

La medida comentada era largamente esperada por el entorno industrial dado que no será sino el colofón de las medidas tomadas en Europa, Norte y Sur América y en muchos países latinoamericanos donde como en el caso de Venezuela se realizó en 1974 una descentralización industrial a fondo, dándose 14 a 20 años para el tralado de la industria mediana y mayor al interior del país, en 1975 se instituyó un Ministerio del Ambiente con un énfasis tal que prácticamente no se podrá implementar industria sin un estudio de Impacto Ambiental debidamente discutido y aprobado por las instituciones municipales y regionales.

El decreto Ley N° 611 que aprueba el Código del Medio Ambiente y los Recursos naturales instaura en un artículo 8 la necesidad de la presentación de un estudio de "Impacto Ambiental" con cada proyecto, por lo que no será posible instalar una empresa industrial en el Perú sin realizar el documento que establece la influencia de la empresa  (en el entorno) en relación a la contaminación. El presente artículo define una metodología ya comprobada en Venezuela para la presentación de un "Estudio de Impacto Ambiental".

La escasez de agua en Lima y la cada vez más agobiantes falta de Energía Eléctrica, presionará para que la medida se complemente con una necesaria ley de descentralización industrial que prohiba la implantación de nueva industria en la capital, tal vez a través de dos grandes zonas industriales una en el norte y otra en el sur de Lima, situadas por lo menos a 100 km. de la capital; dando facilidades y soporte a una industrialización de tipo regional dentro de ciertos requisitos que regulen el buen uso del medio ambiente  en las ciudades que pueda ser afectadas por las industrias a instalarse.

Presentamos en este número la primera parte de una artículo compuesto de 3 segmentos en la que se expone la estructura para realizar un "Estudio de Impacto Ambiental" para la instalación de una industria.
Los gases sulforosos y la problemática del ácido sulfúrico en el Perú
Authors: Jarufe Zedán Benjamín
Published: May 2022

Los gases sulfúricos de nuestras refinerías contienen SO2' el cual constituye el peor contaminante atmosféricode nuestra época, causa estragos a la ecología y daña terriblemente nuestro entorno.

El problema de la desulfuración se resuelve actualmente utilizando el proceso más económico que consiste en aprovechar el SO2 para convertirlo en ácido sulfúrico.

A la fecha existen 4 plantas de ácido sulfúrico con una capacidad instalada de 296 000 t/año, sin contar con la planta que instalará la Southern el próximo año. Pero el país consume solamente unas 100 000 t/año. ¿Qué hacer?.

Además, el Perú es un país eminentemente minero y la explotación de sus recursos naturales nos proporciona ni riqueza. Esto conlleva la necesidad de incrementar la capacidad de refinación de nuestros minerales, pero los gases sulfurosos que se desprendan de las refinerías de cobre, zinc o plomo represenarán una materia prima potencial para seguir produciendo mayores cantidades de ácido sulfúrico.

La opción que nos queda es pensar en la reducción del SO2, a azufre elemental, proceso menos económico que el proceso del ácido sulfúrico, pero necesario para resolver esta problemática.

El cosmos descuartizado
Authors: Regal Alberti Bernardo
Published: May 2022

Se plantean en este artículo tres áreas sustanciales de conocimientos astrofísicos: 1. La estructura actual del Universo galáctico luego de 15 mil millones de años de expansión y evolución. 2. Los comienzos, orígenes y génesis del cosmos, es decir el punto cero a partir del cual tienen sentido espacio y tiempo para las ciencias físicas. 3. El final del cosmos (en sus dos posibilidades de universo abierto o universo cerrado).

Es del máximo interés deslindar estos tres campos y enseñarles a los estudiantes a efectuarlo también. Dicho de otro modo es importante proceder filosóficamente distinguiendo con la misma claridad entre ciencia, metafísica y religión.

The Fractal Nature of Drought: Power Laws and Fractal Complexity of Arizona Drought
Authors: Azizi Tahmineh , Azizi Sepideh
Published: May 2022

In this study, we explore the possibility that the Drought Monitor database belongs to class of fractal process which can be characterized using a single scaling exponent. The Drought Monitor map identifies areas of drought and labels them by intensity: D0 abnormally dry, D1 moderate drought, D2 severe drought, D3 extreme drought, and D4 exceptional drought. The vibration analysis using power spectral densities (PSD) method has been carried out to discover whether some type of power-law scaling exists for various statistical moments at different scales of this database. We perform multi-fractal analysis to estimate the multi-fractal spectrum of each group. We apply Higuchi algorithm to find the fractal complexity of each group and then compare them for different time intervals. Our findings reveal that we have a wide range of exponents for D0-D4. Therefore, D0-D4 belong to class of multi-fractal process for which a large number of scaling exponents are required to characterize the scaling structure.
Paulo Freire in Science Education: Trends and Articulations between Scientific Literacy and the STSE Movement
Authors: Kauano Rafael Vitame , Marandino Martha
Published: May 2022

This work aims to articulate Paulo Freire’s studies and the field of science education. We focus on the scientific literacy (SL) perspective and on the mediations on Science, Technology, Society, and Environment (STS/STSE) Education. In his work, the roles of literacy and dialogue are a key to understanding both the common grounds and tensions with scientific literacy and STS/STSE. We recognize that Freire is present in the foundations of STS/STSE studies, however there is still a distance between this body of work and SL in Brazil, especially in its deeper social senses. This is a significant theoretical and practical challenge, as it is necessary to emphasize socio-political assumptions on science education in view of the unfavorable scenario for Brazilian education in its entirety.
Ecologies of Anxiety
Authors: Gauvin Mitchell
Published: May 2022

This paper examines the urban space as an ecology of anxiety in post-9/11 literature. After the atomic bomb drop on Hiroshima in August 1945, survivors testified of experiencing prior to the bombing an anticipatory trauma known as bukimirooted in the belief that a catastrophic event was forthcoming. Paul K. Saint-Amour suggests that similar experiences to bukimi are not exclusive to the residents of Hiroshima but came to structure post-war urban experience as a result of a nuclear condition wrought by the Cold War. My paper explores whether a contemporary bukimi can be identified in post-9/11 literature. The post-9/11 novel—works which directly or indirectly acknowledge the terrorist attacks—present familiar but ambiguous forms of risk engendered by the threat of terrorism and maintained in the form of an urban-originated anxiety. This anxiety is rooted in the spectre of an event that’s never total or conclusive—an event that promises witness testimony and the maintenance of traumatic memories, but which also eclipses calamitous structures (like global warming) that are gradual and continuous. To unravel this contemporary species of bukimi, my paper examines depictions of the urban space in the post-9/11 literature of Foer and McEwan.

Beyond the Glass Cliff: A Scoping Review of the Influencing Factors of Glass Cliff
Authors: KARAKAPLAN ÖZER Emine
Published: May 2022

Glass ceiling syndrome is the exposure of women to some inequalities while climbing the career ladders. It is an invisible barrier above the women that prevents them from being promoted. Women who achieve to break the glass ceiling get the leadership positions but it is possible for them to face to a new adventure called glass cliff. Glass cliff is the appointment of women to more risky, problematic or unstable leadership positions compared to men. These deliberate promotions, which can cause loss of prestige and an image of failure, are generally not rejected as they are still an opportunity for women. The aim of this study is to reveal the influencing factors of glass cliff. Within the framework of this purpose, a scoping review was carried out. In this review, papers on glass cliff indexed in Web of Science and Scopus databases between 2000-2021 are examined. The results of the study revealed that there are five factors that are commonly referred in reviewed articles. These factors are; stereotypes of leadership and gender, company performance, need for change, leadership ability and leadership suitability.

O Estado de Alagoas apresenta remanescentes naturais extremamente importantes e representativos quanto à biodiversidade. Entretanto, nota-se uma carência de levantamentos florísticos neste Estado, o que pode dificultar a elaboração de políticas de conservação. Diante disso, esse trabalho foi realizado com o intuito de listar as espécies de plantas vasculares ocorrentes em cinco áreas de remanescentes em Alagoas. Foram selecionadas cinco áreas: Reserva Particular do Patrimônio Natural Placas, Parque Municipal de Maceió, Estação Ecológica (ESEC) de Murici, ESEC Curral do Meio e Fragmento Varrela. O inventário florístico foi compilado a partir de bibliografia, dados secundários e expedições botânicas. O relacionamento florístico entre os remanescentes foi avaliado a partir de análises de similaridade florística. Os resultados revelaram a existência de 501 espécies, das quais seis espécies estão ameaçadas de extinção. As famílias com o maior número de espécies foram Fabaceae (75 spp.), Rubiaceae (36 spp.) e Malvaceae e Myrtaceae (21 spp. cada). A maioria das espécies (73%) possui distribuição geográfica restrita, i.e., confinadas a um único remanescente. Foram observados valores baixos de similaridade florística (0.20), provavelmente explicados por heterogeneidade ambiental e distância geográfica. A presença de espécies ameaçadas de extinção e a singularidade florística observada reforçam a necessidade de conservação desses remanescentes.

TRANSFORMATION OF ECONOMIC POLICY PRIORITIES UNDER COVID-19

The aim of this paper is to analyze the main challenges of the new paradigm of economics in the context of Covid 19, the economic role of the state and the scale of state intervention in the economy. Economics teaches us that there is a time for budget expansion and a time for budget constraints. There are times when the government has to intervene in the value chain and there are times when it has to leave the markets alone. Sometimes the tax has to be high and sometimes low. Trade in some areas should be more independent and regulated elsewhere. Globalization is one of the primary variables impacting the state's economic condition in the modern world. The most important function of the state in the context of globalization is not only to protect the national economy from external influences (so-called "external shocks"), which is virtually impossible today, but also to effectively participate in international economic ties and increase the country's global competitiveness. In this aspect, the contemporary state plays a critical role. In turn, Georgia must construct a "Georgian model" of economy that will serve as the "core" of an economic model that would attract investment (in the real economy), generate employment, expand exports, and deliver true prosperity to all Georgians. Today is the day when, at the state's initiative, the country's economic priorities are defined and the country's distinctive economic potential is fulfilled. The modern economic crisis, which was triggered by the Covid-pandemic, has demonstrated that a route out of the current predicament is conceivable when the anti-crisis strategy is based on increased government participation in the economy. To accomplish so, the government and the public sector must play a larger role in crisis management. Despite these examples, the economic regulation of the state has always had strategic and tactical significance. For any country, there are and will always be state problems that are either not addressed through the supply-demand mechanism or are associated with negative side effects. Based on the existence of such cases, a set of free market economic measures is being developed through state programming of the economy and the use of regulatory tools. In view of the above, it is necessary to reconsider and reform the role and rights of the state in modern economic relations. The need to establish the state as a factor of progressive development in the economy should be emphasized during the reform. In addition, it should include legislative activities such as – compliance with labor safety conditions, regulation of the minimum wage, resolution of social conflicts, etc.
