Published: September 2023

Ribonucleic acids (RNAs) remain challenging targets for structural biology, creating barriers to understanding their vast functions in cellular biology and fully realizing their applications in biotechnology. The inherent dynamism of RNAs creates numerous obstacles in capturing their biologically relevant higher-order structures (HOSs), and as a result, many RNA functions remain unknown. In this report, we describe the development of native ion mobility-mass spectrometry (IM-MS) and collision induced unfolding (CIU) for the structural characterization of a variety of RNAs. We evaluate the ability of these techniques to preserve native structural features into the gas-phase across a wide range of functional RNAs. Finally, we apply these tools to study the elusive mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS)-associated A3243G mutation. Our data demonstrate that our experimentally determined conditions preserve some solution-state memory of RNA via the increasing complexity of CIU fingerprints by RNA HOS and the retention of predicted magnesium binding events. Relating to the role of MELAS-inducing mutations in mitochondrial trans-fer RNA (mt-tRNAs), significant differences in collision cross-section (CCS) and stability are observed as a function of the A3243G mutation across a subset of the mitochondrial transfer RNA (tRNA) maturation pathway. We conclude by discussing the potential application of CIU for the development of RNA-based biotherapeutics and, more broadly, transcriptomic characterization.
Persistence on Quotient Spaces with G-invariant Covering for Structural Analysis
Authors: Chen Zhenghong
Published: September 2023

Persistent homology, building its foundation on homology theory, has been successfully applied various fields containing computation of topology. Here, we derive and implement persistent homology theory to specefic topological spaces with G-invariant covering, whereby persistence over quotient space can be canonically formed. The implementation is validated by comparing against various transformation homomorphisms. Furthermore, it is proved that implementation over normal covering spaces can preserve persistence barcode diagram if charateristic of coefficient is coprime to |G|. These results shed light on potential application of persistent homology to clusters or crystallography in a view of hierarchy structure induced by symmetry.
Review of Low-cost Self-driving Laboratories: The "Frugal Twin" Concept
Authors: Lo Stanley , Baird Sterling , Schrier Joshua , Blaiszik Ben , Kalinin Sergei , Tran Helen , Sparks Taylor , Aspuru-Guzik Alán
Published: September 2023

This review proposes the concept of a “frugal twin,” similar to a digital twin, but for physical experiments. Frugal twins range from simple toy examples to low-cost surrogates of high-cost research. For example, a color-mixing self-driving laboratory (SDL) is a low-cost version of a costly multi-step chemical discovery SDL. We need frugal twins because they provide hands-on experience, a test bed for software prototyping (e.g., optimization, data infrastructure), and a low barrier to entry for democratizing SDLs. However, there is room for improvement. The true value of frugal twins can be realized in three core areas. Firstly, hardware and software modularity, secondly, purpose-built design (human-inspired vs. hardware-centric vs. human-in-the-loop), and thirdly state-of-the-art (SOTA) software (e.g., multi-fidelity optimization). We also describe the ethical benefits and risks that come with the democratization of science through frugal twins. In future work, we suggest ideas for new frugal twins, SDL educational course outcomes, and a classification scheme for autonomy levels.
Manganese Catalysed Synthesis of Polyketones Using Hydrogen Borrowing Approach
Authors: Kulyabin Pavel , Naden Aaron B , Dawson Daniel M , Payne Julia L , Kumar Amit
Published: September 2023

We report here a new method to make polyketones from the coupling of diketones and diols using a manganese pincer complex. The methodology allows us to access a new type of polyketone (polyarylalkylketone) containing aryl, alkyl, and ether functionalities bridging the gap between the two classes of commercially available polyketones – aliphatic polyketones and polyaryletherketones. Based on previous reports and our studies, we suggest that the polymerization occurs via a hydrogen-borrowing mechanism that involves the dehydrogenation of diols to dialdehyde followed by aldol condensation of dialdehyde with diketones to form chalcone derivatives and their subsequent hydrogenation to form polyarylalkylketones.

Published: September 2023

Carbene is the pivotal reactive intermediate and its reactivity potential has been extensively explored in a variety of synthetic transformations ranging from cycloaddition to site-selective C–H functionalizations. However, controlling the reactivity of carbene is a key parameter for achieving the selective carbene transfer reactions. Usually, strategies rely on the combined effect of metal catalysts and ligands to accomplish the selective transformations via the generation of singlet carbene intermediate. Contrarily, the triplet carbene has gained a very little attention from the researchers as its generatation and reactivity relies on the use of specific metal complexes thus limiting its wider utility. Neverthless, the organic transformations involving a triplet spin state carbene have been explored with diazo compounds under visible light utilizing photosensitizer. However, the development of the visible light induced sensitizer-free strategy for the generation of triplet carbene is highly challenging and is seldom reported. Herein, we have demonstrated vinyl diazosuccinimide as a new class of diazo compound which upon exposure to blue LEDs (456 nm) generates ground-state triplet carbene (without ISC) in the absence of any photosensitizer. We have successfully explored this strategy and utilzed to construct the biologically relavant scaffold such as 2H-chromenes. A series of control experiments, EPR studies as well as DFT calculations have supported the existence of ground-state triplet carbene followed by the aryloxy radical during the course of the reaction.

Authors: DIALLO Mamadou Kalan
Published: September 2023

Materials engineering and catalysis are known as central sciences, which can deeply contribute to the technological development of our nations, and as well as ensure the environmental protection and cleaning from both organic and inorganic contaminants. So, the generation of the most wanted chemical and fuels such as (CH4) or to carbon monoxide (CO/H2), methanol (CH3OH) or even to hydrogen (H2) and ammonia (NH3) requires strongly active, selective, stable, and as well as reusable materials (catalysis) to fulfill the mankind needs. The determination and removing both inorganic and organic are highly regarded special issue in healthcare. So that, all these areas strong materials for the complete transformation of these chemical products. Indeed, zeolite materials are very explored in the recent years as they present advanced properties in both catalysis and environmental concerns. Also, its combination with transition noble and non-noble metals are also considered in order to boost the catalytic yields. In fact, here, it is ascribed the role of transition rare-earth (RE) elements in the hybrid materials engineering for advanced technological applications. It demonstrated that rare earth oxides might enhance catalytic features and avoid the loss of acid sites under the fluid catalytic craking (FCC) unit operation. Moreover, It is shown that (RE) elements might be used for materials engineering for high-tech uses such as in hydrogen evolution reaction (HER), methanol oxidation reaction (MOR), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). Many other reactions can be realized over hybrid materials made via the use of rare earth (RE) elements with improved catalytic performances. Therefore, due to the large properties of transition rare-earth (RE) metals, more possible superb materials will be engineered in upcoming generation.

Published: September 2023

Hydrocarbon-based lubricants are ubiquitous in industrial applications but are typically complex mixtures of branched molecules that are challenging to characterize and to relate to their macroscopic properties. Consequently, lubricants are typically optimized empirically for specific applications by blending base oils and organic or inorganic additives. Here, we report the synthesis and characterization of molecularly defined lubricants via metathesis of branched terminal olefins followed by hydrogenation of the internal olefin products. The resulting saturated hydrocarbons are characterized by ultra-high-field (28.2 T) 1H and 13C NMR spectroscopies to establish their molecular structures and resolve different stereoisomers, showing the utility of state-of-the-art spectroscopic tools for resolving structures of branched alkanes. Furthermore, the molecular-level diffusion and bulk viscosity properties compare favorably to classical synthetic lubricants based on hydrogenated polyalphaolefin blends, establishing olefin metathesis as a selective and scalable route to high-performance lubricant oils with defined molecular structures.

Microcapsules with aqueous core can be conveniently prepared by water-in-oil-in-water double emulsion microfluidics. However, conventional shell materials are either based on polymers or monomers that are soluble in the oil phase, or based on hydrophobic colloidal particles. As a result, microcapsules derived from double emulsions usually feature a hydrophobic shell that is not semipermeable for water-soluble compounds. While capsules with semipermeable hydrogel shells have been demonstrated, these may exhibit poor mechanical properties and lack the robustness required in many applications. In this study, amphiphilic polymer conetworks (APCNs) based on poly(2-hydroxyethyl acrylate)-linked by-polydimethylsiloxane (PHEA-l-PDMS) are introduced as a new class of wall materials in double emulsion microcapsules. These APCNs are mechanically robust silicone hydrogels that are swellable and permeable to water, and are soft and elastic in the dry and swollen states. Thus, the microcapsules can be dried and rehydrated multiple times or shrunken in sodium chloride salt solutions without getting damaged. Moreover, the APCNs are semipermeable for hydrophilic organic compounds, while being impermeable for macromolecules and colloids. Thus, they can be loaded with macromolecules or nanoparticles during microfluidic formation, and with organic molecules after capsule synthesis. Uptake into and release from the capsules were studied with the model compounds fluorescein and fluorescently labelled dextran. Moreover, the microcapsules served as microreactors for catalytically active platinum nanoparticles that decomposed hydrogen peroxide. Finally, the surface of APCN microcapsules can be selectively functionalized with a cholesterol-based linker that non-covalently binds to the hydrophobic domains of the APCN. Thus, APCN microcapsules represent versatile and broadly applicable capsules that could find application for the controlled delivery of drugs, as microreactors for synthesis, or even as scaffolds for synthetic cells.
Honeycomb Layered Frameworks with Metallophilic Bilayers

Published: September 2023

Honeycomb layered frameworks have garnered traction in a wide range of disciplines owing not only to their unique honeycomb configuration, but also to the plenitude of physicochemical and topological properties such as fast ionic conduction, diverse coordination chemistry and structural defects amongst others typically exploited for energy storage applications. In turn, honeycomb layered frameworks manifesting metallophilic bilayer arrangements of cations sandwiched between the transition metal cation slabs have recently garnered attention due to the presence of anomalous fractional valency state of the cations always accompanied by metallophilic interactions constituting the cationic bonds within the bilayered structure. The concepts needed to characterise the aforementioned peculiarities and other phenomena such as conductor-semiconductor-insulator phase transition and magnetoresistance in these materials cut across multi-disciplines ranging from materials science and solid-state chemistry to condensed matter physics, suggesting applications that fall beyond energy storage. This Review highlights the exciting advancements in the science of honeycomb layered frameworks with metallophilic bilayers. First, the latest tactics and techniques including but not limited to X-ray absorption spectroscopy (XAS) and high-resolution transmission electron microscopy (HRTEM) particularly necessary for characterising recent honeycomb layered frameworks with metallophilic bilayers are described, with emphasis on silver-based oxides. Second, new strategies and concepts related to topochemically- or temperature-induced cationic-deficient phases expanding the compositional space of honeycomb layered frameworks focused on cationic bilayer architectures are also accentuated. Third, the latest condensed matter theoretic advances towards a full, atomistic description of the bilayered structure in such frameworks are detailed, especially related to critical phenomena at the cusp of the monolayer-bilayer phase transition. This entails, in part, describing honeycomb layered frameworks as optimised lattices within the congruent sphere packing problem, equivalent to a particular two-dimensional (2D) conformal field theory. Within this picture, the monolayer-bilayer phase transition represents the bifurcation of the honeycomb lattice into its bipartite constituents, related to a 2D-to-3D crossover. Altogether, it is hoped that this Review will give the reader a panoramic view of the honeycomb layered frameworks with important applications within the emerging field of quantum matter, potentially redefining their frontier. Thus, the scope of this Review is expected to be worthwhile for recent graduates and emerging experts alike not only in the materials science and chemistry community but also in other diverse fields of interest.

Published: September 2023

Here, we report synthesis of magnetic nanocomposite with zero-waste approach for organic pollutant removal and oxygen evolution reaction. The nanocomposite was synthesized using agriculture waste soaked with Co2+-Fe3+ metal ions at 900 °C and characterized using FESEM, HRTEM, PXRD, Zeta-potential, and VSM techniques. The nanocomposite shows an impressive adsorbent property for organic dyes (90-96 % removal), and pharmaceutical drug (paracetamol, 84% removal), along with individually used ‘hair dye’ (95% removal) in 5 min only. The recyclability of the nanocomposite demonstrates the practical benefits of the material for waste water remediation. Interestingly, after the adsorption, the generated secondary waste (exhausted dye adsorbed nanocomposite) is used as oxygen evolution reaction (OER) electrocatalyst. The dye-adsorbed nanocomposite shows good OER activity with an overpotential of 264 mV at 10 mA/cm2 with good stability upto 10 h. This study sheds light on the reuse and recycling of the secondary waste of the adsorption process to develop efficient OER electrocatalysts and shows a zero-waste approach towards the environment.
Uncertain of uncertainties? A comparison of uncertainty quantification metrics for chemical data sets
Authors: Rasmussen Maria H. , Duan Chenru , Kulik Heather J. , Jensen Jan Halborg
Published: September 2023

With the increasingly more important role of machine learning (ML) models in chemical research, the need for putting a level of confidence to the model predictions naturally arises. Several methods for obtaining uncertainty estimates have been proposed in recent years but consensus on the evaluation of these have yet to be established and different studies on uncertainties generally uses different metrics to evaluate them. We compare three of the most popular validation metrics (Spearman’s rank correlation coefficient, the negative log likelihood (NLL) and the miscalibration area) to the error-based calibration introduced by Levi et al. (Sensors 2022, 22, 5540). Importantly, metrics such as the negative log likelihood (NLL) and Spearman’s rank correlation coefficient bear little information in themselves. We therefore introduce reference values obtained through errors simulated directly from the uncertainty distribution. The different metrics target different properties and we show how to interpret them, but we generally find the best overall validation to be done based on the error-based calibration plot introduced by Levi et al. Finally, we illustrate the sensitivity of ranking-based methods (e.g. Spearman’s rank correlation coefficient) towards test set design by using the same toy model on two different test sets and obtaining vastly different metrics (0.05 vs. 0.65).

Chemically self-charging aqueous zinc-ion batteries (AZIBs) via air oxidation will provide new opportunities for future wearable electronic devices. Herein, we display two high-performances flexible AZIBs based on trifluorohexaazatrinaphthylene (TFHATN)/trichlorohexaazatrinaphthylene (TCLHATN) cathode, which can be recharged via air without using external power supply. The flexible Zn//TFHATN/Zn//TCLHATN battery presents good mechanical flexibility and high volumetric energy density of 9.2/10.7 mWh cm-3. The air-recharging capability originates from a spontaneous redox reaction between the discharged TFHATN/TCLHATN cathode and O2 from air. After exposed to air for 15 h, the discharged Zn//TFHATN/Zn//TCLHATN battery can be recharged to 1.2 V around, exhibits high discharge capacity, high-rate performance, higher self-charging cycle stability (8 cycles), and works well in chemical or/and galvanostatic charging mixed modes, displaying good reusability. This work provides a strategy for developing high-performance flexible air-rechargeable AZIBs.

Published: September 2023

Хотя идеологические кампании в науке принято связывать с ХХ в., в наши дни они тоже имеют место. В 2018–22 гг. они происходили в Венгрии, Болгарии, Германии и Великобритании. Под видом нормальной науки со-здавалась мнимая. В статье представлены границы реальной и мнимой науки, критерии их демаркации. Также статья демонстрирует, что в ситу-ации идеологического контроля науки, научная парадигма зависит от па-радигмы технологической, которая, в свою очередь, обусловливается тех-нико-экономической парадигмой. Сделаны выводы о зависимости техно-логической парадигмы от технико-экономической, о том, что современ-ные идеологические кампании в науке могут завершиться, если начнут вступать в противоречия с технологическими и технико-экономическими парадигмами.

Although ideological campaigns in science are often associated with the 20th century, they still exist today. In 2018-22, such campaigns occurred in Hun-gary, Bulgaria, Germany, and the United Kingdom. Instead of real science, a false one was created. This article presents the boundaries between real and false science, the criteria for their demarcation, and how they are demonstrated. The article also shows that in situations of ideological control over science, the scientific paradigm depended on the technological paradigm, which, in turn, depended on the techno-economic paradigm. Conclusions are drawn about the dependence of the technological paradigm on the techno-economic one and that modern ideological campaigns in science may come to an end if they begin to contradict technological and techno-economic paradigms.

PEACE/WORLD ORDER AS THE BASIS OF THE SOCIAL IN THE DOCTRINE OF MARSILIUS OF PADUA
Authors: Козлова Н.Н. , Рассадин С.В.
Published: September 2023

Авторы исследуют дискурсивное конструирование «Социального» в труде Марсилия Падуанского «Защитник мира». Авторы полагают, что итальянский мыслитель осуществил конвергенцию перипатетического и теологического дискурсов с применением органического инструментария. Раскрывается функциональный подход итальянского мыслителя, выраженный в поиске конфигурации институтов «Социального», обеспечивающих мир и спокойствие общества. В рамках дискуссии о степени радикальности взглядов Марсилия Падуанского предлагается умеренная трактовка его концепции народного суверенитета: при сохранении средневековой теологической конструкции бытия, в котором «вся власть от Бога», источник власти в «этом мире» выводится за пределы теологического дискурса. Авторы считают, что пересборка «Социального» в труде Марсилия Падуанского предполагает новый аксиологический и институциональный порядок, в котором основополагающей ценностью и организацией является единая неделимая политическая власть в лице государства, обладающая верховенством в процессе принятия решений.

The authors explore the discursive construction of the «Social» in the work of Marsilius Padua «Defender of Peace». The authors assume that the Italian thinker accomplished the convergence of peripatetic and theological discourses using organic tools. The functional approach of the Italian philosopher is revealed, expressed in the search for the configuration of the institutions of the «Social», ensuring the peace and tranquility of society. As part of the discussion on the degree of radicality of the views of Marsilius of Padua, a moderate interpretation of his concept of popular sovereignty is proposed: while preserving the medieval theological construction of being in which «all power is from God», the source of power in «this world» is removed from the limits of theological discourse. The authors believe that the reassembly of the «Social» in the work of Marsilius of Padua presupposes a new axiological and institutional order in which the fundamental value and organization is a single indivisible political power represented by the state, which has supremacy in the decisionmaking process.

Prostate cancer (PCa) poses a significant health threat to males, and research has shown that fish oil (FO) can impede PCa progression by activating multiple mitochondria-related pathways. Our research is focused on investigating the impact of FO on succinylation, a posttranslational modification that is closely associated with mitochondria in PCa cells. This study employed a mass spectrometry-based approach to investigate succinylation in PCa cells. Bioinformatics analysis of these succinylated proteins identified glutamic–oxaloacetic transaminase 2 (GOT2) protein as a key player in PCa cell proliferation. Immunoprecipitation and RNA interference technologies validated the functional data. Further analyses revealed the significance of GOT2 protein in regulating nucleotide synthesis by providing aspartate, which is critical for the survival and proliferation of PCa cells. Our findings suggest that FO-dependent GOT2 succinylation status has the potential to inhibit building block generation. This study lays a solid foundation for future research into the role of succinylation in various biological processes. This study highlights the potential use of FO as a nutrition supplement for managing and slowing down PCa progression.
Perspectives and attitudes towards sustainability among science, preschool, and primary school teachers
Authors: Savas Pamuk
Published: September 2023

The concept of sustainability has been gaining momentum in recent years as people are becoming increasingly aware of the environmental, social, and economic challenges facing the world. Sustainability is a complex issue that requires a multidisciplinary approach and long-term perspective. This study aimed to examine the perceptions and attitudes of science, primary school, and preschool teachers toward sustainability. The study involved 299 public school teachers, who were asked to complete a series of scales and questions to gauge their views on sustainability and sustainable development. The findings of this study indicate that preschool teachers take a more holistic approach to sustainability education, emphasizing the need to teach sustainability as a lifestyle and calling for improved teacher training in this area. On the other hand, primary school teachers placed greater emphasis on raising awareness of sustainability rather than inducing basic behavioral changes in children. Science teachers were more focused on acquiring knowledge and concepts related to sustainability. Overall, the study suggests that the effective implementation of sustainability education requires supporting materials and resources, and the support of school administration and families.
Effectiveness of authentic learning practices in turkey: A meta-analysis
Authors: Özgür Tutal
Published: September 2023

Authentic learning is gaining attention due to being perceived as a more engaging and effective way of teaching students. Many schools are incorporating authentic learning into their curricula, and numerous studies have also been conducted investigating the effectiveness of authentic learning in improving student outcomes. Various primary studies have been conducted in Turkey examining the effect of authentic learning on academic achievement and learning retention, which have an important place among learning outcomes. It was observed that the results of these individual studies reported different effect sizes on the effectiveness of authentic learning. This review aimed to report the overall effect sizes by analyzing the results of experimental and quasi-experimental studies examining the effect of authentic learning on academic achievement and learning retention through meta-analysis. Of the 180 studies listed as a result of the literature search, 11 studies (13 effect sizes) for academic achievement and four studies (six effect sizes) for the learning retention variables that meet the inclusion criteria were coded and analyzed. The results of the analysis showed a moderate overall effect size for the effectiveness of authentic learning on both academic achievement (g = 0.991) and learning retention (g = 0.925). It is possible to say that the overall effect sizes obtained as a result of the meta-analysis are moderate, quite remarkable for educational research, and that authentic learning is more effective in increasing academic achievement and learning retention than traditional education processes.
Co-caring relationships: How parent and child characteristics matter
Authors: Mustafa Çetin
Published: September 2023

This study aims to investigate the relationships between parent and child characteristics and co-caring relationships with the child's preschool teacher, including endorsement, support, undermining, and agreement. A survey research design was adopted for this study. The study's data were collected from 243 mothers and 238 fathers selected from preschools in Antalya, Turkey, through a demographic information form and the Co-caring Relationship Questionnaire. Independent sample t-tests, One-Way Analysis of Variance (ANOVA), and simple linear regression analyses were conducted. The results of the analyses indicated that there is a statistically significant difference between mothers and fathers in relation to their child's teacher in terms of endorsement, support, and undermining. On the other hand, the co-caring relationships of parents with their child's teacher did not differ based on the child's gender or parents' educational level. Lastly, the results revealed that parents' age significantly predicted the endorsement of parents for teachers' caregiving.
The Russia-Ukraine Conflict: Obstacles to Accountability
Authors: Weiner Allison
Published: September 2023

The Russia-Ukraine conflict has left much of the international community increasingly concerned about violations of international law and the strength of the international legal system's ability to end impunity. With such a young international legal system, having yet to reach its 100th birthday, precedents are still fresh and being set with each new case. Each investigation opened by the International Criminal Court (ICC) encounters new uncharted territory. Using legislation foundational to the modern international system, this article seeks to analyze and understand the unique impact of Russian aggression against Ukraine on the present-day system of international law. This evaluation provides a quasi-directive on how the international system can move forward in the fight against international impunity.
Prevalencia de enfermedad gingival en niños con dentición primaria

Published: September 2023

La gingivitis se define como la inflamación de la encía. Algunos hallazgos clínicos iniciales incluyen enrojecimiento e inflamación del margen gingival y sangrado después del sondeo. Si las condiciones persisten, los tejidos que fueron inicialmente edematosos comienzan a volverse fibróticos. La encía clínicamente sana en el preescolar suele ser más rojiza, por una mayor vascularización; tiene un epitelio más delgado, menos queratinizado y más translúcido. La superficie gingival puede ser lisa o levemente moteada y los tejidos pueden mostrar una consistencia más firme y elástica. Otros factores que pueden afectar la ocurrencia y severidad de gingivitis en niños son respuesta inmunológica de las células inflamatorias, cambios en la composición bacteriana de la placa dental, diferencias morfológicas en la dentición primaria, presencia de apiñamiento y traumatismo por cepillado factores demográficos, socioeconómicos y estrés. La gingivitis en niños asmáticos puede ser explicada, debido a una alteración de la respuesta inmune y por la tendencia de respiración bucal, especialmente durante un episodio de ataque asmático y deshidratación de la mucosa alveolar durante la respiración bucal. La concentración de IgE encontrada en los tejidos gingivales es elevado en los pacientes con asma, causante de la destrucción periodontal. La Academia Americana de Odontología Pediátrica promueve medidas preventivas profesionales y en casa, que incluyen: implementar medidas de higiene oral a partir de la erupción del primer diente primario, el cepillado debe ser realizado por sus padres dos veces al día, utilizando un cepillo de dientes suave de tamaño adecuado a la edad. Se aplicó una metodología descriptiva, con un enfoque documental, es decir, revisar fuentes disponibles en la red, con contenido oportuno y relevante para dar respuesta a lo tratado en el presente artículo.
