AbstractRenewable electricity driven electrocatalytic CO2 reduction reaction (CO2RR) is a promising solution to carbon neutralization, which mainly generate simple carbon products. It is of great importance to produce more valuable C−N chemicals from CO2 and nitrogen species. However, it is challenging to co‐reduce CO2 and NO3−/NO2− to generate aldoxime an important intermediate in the electrocatalytic C−N coupling process. Herein, we report the successful electrochemical conversion of CO2 and NO2− to acetamide for the first time over copper catalysts under alkaline condition through a gas diffusion electrode. Operando spectroelectrochemical characterizations and DFT calculations, suggest acetaldehyde and hydroxylamine identified as key intermediates undergo a nucleophilic addition reaction to produce acetaldoxime, which is then dehydrated to acetonitrile and followed by hydrolysis to give acetamide under highly local alkaline environment and electric field. Moreover, the above mechanism was successfully extended to the formation of phenylacetamide. This study provides a new strategy to synthesize highly valued amides from CO2 and wastewater.

AbstractChiral perovskites possess a huge applicative potential in several areas of optoelectronics and spintronics. The development of novel lead‐free perovskites with tunable properties is a key topic of current research. Herein, we report a novel lead‐free chiral perovskite, namely (R/S−)ClMBA2SnI4 (ClMBA=1‐(4‐chlorophenyl)ethanamine) and the corresponding racemic system. ClMBA2SnI4 samples exhibit a low band gap (2.12 eV) together with broad emission extending in the red region of the spectrum (∼1.7 eV). Chirality transfer from the organic ligand induces chiroptical activity in the 465–530 nm range. Density functional theory calculations show a Rashba type band splitting for the chiral samples and no band splitting for the racemic isomer. Self‐trapped exciton formation is at the origin of the large Stokes shift in the emission. Careful correlation with analogous lead and lead‐free 2D chiral perovskites confirms the role of the symmetry‐breaking distortions in the inorganic layers associated with the ligands as the source of the observed chiroptical properties providing also preliminary structure‐property correlation in 2D chiral perovskites.
Designing Multifunctional Biomaterials via Protein Self‐Assembly
Authors: Solomonov Aleksei , Kozell Anna , Shimanovich Ulyana 
Published: January 2024

AbstractProtein self‐assembly is a fundamental biological process where proteins spontaneously organize into complex and functional structures without external direction. This process is crucial for the formation of various biological functionalities. However, when protein self‐assembly fails, it can trigger the development of multiple disorders, thus making understanding this phenomenon extremely important. Up until recently, protein self‐assembly has been solely linked either to biological function or malfunction; however, in the past decade or two it has also been found to hold promising potential as an alternative route for fabricating materials for biomedical applications. It is therefore necessary and timely to summarize the key aspects of protein self‐assembly: how the protein structure and self‐assembly conditions (chemical environments, kinetics, and the physicochemical characteristics of protein complexes) can be utilized to design biomaterials. This minireview focuses on the basic concepts of forming supramolecular structures, and the existing routes for modifications. We then compare the applicability of different approaches, including compartmentalization and self‐assembly monitoring. Finally, based on the cutting‐edge progress made during the last years, we summarize the current knowledge about tailoring a final function by introducing changes in self‐assembly and link it to biomaterials’ performance.
Garzapelta muelleri gen. et sp. nov., a new aetosaur (Archosauria: Pseudosuchia) from the Late Triassic (middle Norian) middle Cooper Canyon Formation, Dockum Group, Texas, USA, and its implications on our understanding of the morphological disparity of the aetosaurian dorsal carapace

AbstractThe Late Triassic Dockum Group in northwestern Texas preserves a rich diversity of pseudosuchian taxa, particularly of aetosaurs. In this contribution, we present Garzapelta muelleri gen. et sp. nov., a new aetosaur from the Late Triassic middle Cooper Canyon Formation (latest Adamanian–earliest Revueltian teilzones) in Garza County, Texas, based on an associated specimen that preserves a significant portion of its dorsal carapace. The carapace of G. muelleri exhibits a striking degree of similarity between that of the paratypothoracin Rioarribasuchus chamaensis and desmatosuchins. We quantitatively assessed the relationships of G. muelleri using several iterations of the matrix. Scoring the paramedian and lateral osteoderms of G. muelleri independently results in conflicting topologies. Thus, it is evident that our current matrix is limited in its ability to discern the convergence within this new taxon and that our current character lists are not fully accounting for the morphological disparity of the aetosaurian carapace. Qualitative comparisons suggest that G. muelleri is a Rioarribasuchus‐like paratypothoracin with lateral osteoderms that are convergent with those of desmatosuchins. Although the shape of the dorsal eminence, and the presence of a dorsal flange that is rectangular and proportionately longer than the lateral flange are desmatosuchin‐like features of G. muelleri, the taxon does not exhibit the articulation style between the paramedian and lateral osteoderms which diagnose the Desmatosuchini (i.e., a rigid interlocking contact, and an anteromedial edge of the lateral osteoderm that overlaps the adjacent paramedian osteoderm).
Evolution of hard gluons in a medium with q^(t)∼tn and the thermalization problem
Authors: Gregoletto Ben Felipe , Machado Magno V. T. 
Published: January 2024

AbstractWe study the energy distribution of hard gluons traversing a dense quark‐gluon plasma by comparing various transverse momentum broadening rates , using a probabilistic perturbative approach. These results were applied to address the thermalization problem in heavy ion collisions. Within the weak coupling model, thermalization follows a “bottom‐up” process: early‐formed high‐energy partons emit low‐energy gluons, leading to their equilibrium formation, creating a thermal bath that facilitates equilibrium in the high‐energy sector. Under this scenario, we model the time dependencies of as a power‐law , and assess the impact of on the distribution of hard gluons passing through the medium.

AbstractThis research examines the compatibility and performance of various solvents and binders in the battery cathode fabrication. The study focused on the applicability of solvents, including DMF, NMP, p‐Xylene, Ethanol, Toluene, Cyrene, and KJCMPA, in conjunction with binders such as PVDF #9300, PVDF #1100, HSV 1810, PVP, Oppanol N150, and Oppanol B15 for NMC‐based slurry formulation. Each solvent‐binder combination was evaluated with NMC material, and those demonstrating optimal solubility, adhesion, and film quality were selected for cathode screen‐printing trials. Results show that the combination of NMP solvent and HSV 1810 binder outperformed other pairings in cycling stability and capacity retention, achieving 87 % capacity retention after 1,000 1C/1C cycles. Comprehensive analyses using SEM, XRD, and FTIR offered insights into the structural and binder phase characteristics of the fabricated cathodes, especially the alterations in binder crystallinity phases (α, β, and γ). The data suggest that the use of the homopolymer HSV 1810, irrespective of the solvent, results in a pronounced presence of the γ‐phase within the binder, which subsequently improves battery performance. Moreover, the findings underscore the importance of the solvent‐binder combinations in enhancing battery performance and longevity.

Published: January 2024

AbstractThis paper rigorously explores the impact of corporate social responsibility (CSR) assurance on the environmental and social disclosures of S&P 500 firms over the period 2010–2018. Integrating annual financial, CSR assurance and environmental and social disclosures data, our study unveils a positive association between CSR assurance and firms' environmental and social disclosures. In a pioneering analysis, we delve into the nuanced interplay between CSR assurance, female directors and environmental and social disclosures. Intriguingly, our findings reveal a negative and significant interaction between female directors and CSR assurance, shedding light on potential substitutes in shaping environmental and social disclosures. Furthermore, our study uncovers the moderating effect of sensitive industries, indicating a positive relationship between CSR assurance and environmental disclosures. Importantly, these insights remain robust across alternative estimation approaches. This study marks a notable contribution by being the first to scrutinize the implications of CSR assurance on social disclosure, investigate the substitutive role of female directors in comparison with CSR assurance and shed light on the added significance of CSR assurance in firms operating in sensitive industries. Our findings provide valuable insights for corporations and stakeholders amid escalating demands for comprehensive and reliable reporting on environmental and social matters. Likewise, this study underscores the potential policy implications of promoting or mandating CSR assurance, given its positive impact on environmental and social disclosures. Policymakers are urged to consider initiatives fostering gender diversity on boards and industry‐specific approaches to enhance sustainability‐related disclosures, aligning regulatory frameworks with evolving stakeholder expectations.

AbstractBackgroundCurrent standard of care for advanced biliary tract cancer (BTC) is gemcitabine, cisplatin plus anti‐PD1/PD‐L1, but response rates are modest. The purpose of this study was to explore the efficacy and safety of durvalumab (anti‐PD‐L1) and tremelimumab (anti‐CTLA‐4), with and without an interventional radiology (IR) procedure in advanced BTC.MethodsEligible patients with advanced BTC who had received or refused at least one prior line of systemic therapy were treated with tremelimumab and durvalumab for four combined doses followed by monthly durvalumab alone with and without an IR procedure until the progression of disease or unacceptable toxicity. Objective response was assessed through CT or MRI by Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) every 8 weeks. Adverse events (AEs) were recorded and managed. The primary endpoint was 6‐month progression‐free survival (PFS).ResultsTwenty‐three patients with advanced BTC were enrolled; 17 patients were assigned to treatment with durvalumab and tremelimumab (Durva/Treme); and 6 patients were treated with the combination of durvalumab, tremelimumab plus IR procedure (Durva/Treme + IR). The best clinical responses in the Durva/Treme arm were partial response (n = 1), stable disease (n = 5), progressive disease (n = 5), and in the Durva/Treme + IR arm: partial response (n = 0), stable disease (n = 3), progressive disease (n = 3). The median PFS was 2.2 months (95% CI: 1.3–3.1 months) in the Durva/Treme arm and 2.9 months (95% CI: 1.9–4.7 months) in the Durva/Treme + IR arm (p = 0.27). The median OS was 5.1 months (95% CI: 2.5–6.9 months) in the Durva/Treme arm and 5.8 months (95% CI: 2.9–40.1 months) in the Durva/Treme + IR arm (p = 0.31). The majority of AEs were grades 1–2.ConclusionDurva/Treme and Durva/Treme + IR showed similar efficacy. With a manageable safety profile. Larger studies are needed to fully characterize the efficacy of Durva/Treme ± IR in advanced BTC.

AbstractPositron Annihilation Lifetime Spectroscopy (PALS) has been employed to investigate the catalysts HZSM‐5 and MESO−Y, which play a pivotal role in catalyzing and upgrading plastics, with a primary focus on oxygenated polymers, thereby transforming existing plastic materials into simpler, higher‐quality value‐added products. In this study, PALS was systematically compared with other complementary analytical techniques. The research outcomes have successfully demonstrated the efficacy of PALS in elucidating the morphology and topology of zeolites at micro/meso‐meter scales.The first experiment focuses on H‐ZSM‐5 zeolite subjected to treatments involving polyurethane and polypropylene. The second experiment delves into H‐ZSM‐5 zeolites with varying Si/Al ratios, both before and after conversion. The third experiment investigates Y zeolites that are surfactant templated to induce meso‐porosity, examining their fresh state as well as their post‐conversion condition.The PALS analysis was supplemented by BET (Brunauer‐Emmett‐Teller) analysis and NMR (Nuclear Magnetic Resonance) spectroscopies. Notably, PALS exhibits superior sensitivity, at the sub‐nanometer scale, suggesting its potential as a preferred complementary method for catalysis studies. In conclusion, the integration of PALS into the repertoire of analytical tools enhances our understanding of catalyst behavior and catalytic processes, offering valuable insights for the advancement of plastic recycling and catalysis research.

AbstractThis review describes the advances of heterogenous phase‐transfer catalysts onium‐based and their importance from a sustainable point of view. Although heterogeneous phase‐transfer catalysts have shown incredible advantages in many organic reactions, examples of supported phase‐transfer catalysts onium‐based are still limited. In this review, we will examine the most common supports, including polymers, clays, and inorganic materials. Additionally, new recent developments in carbon materials application as efficient heterogeneous phase‐transfer catalysts in water will be reported, opening a new route toward green and sustainable procedures.

AbstractPhotoreduction of CO2 into valuable fuels using semiconductors has been known as a potential mean to simultaneously alleviate environmental and energy issues. Z‐scheme photocatalytic systems can realize spatial separation of photogenerated charges and ensure strong redox capability simultaneously. Particularly, the all‐solid‐state Z‐scheme photocatalysts for non aqueous redox mediators have been widely used for CO2 reduction. This review provides a comprehensive outlook of the essential components and recent advancements in all‐solid‐state Z‐scheme systems designed for the photocatalytic reduction of CO2, including indirect Z‐scheme, direct Z‐scheme system, and mechanism on Z‐scheme surface. Finally, a brief outlook on the challenges and novel courses within this domain is presented, which will give a rational guideline to improve the efficiency of hybrid photocatalysts for Z‐scheme CO2 reduction.

Published: January 2024

AbstractAsymmetric electrosynthesis provides an efficient and controllable route for chiral synthesis. In comparison to traditional symmetric synthesis methods, asymmetric electrosynthesis typically operates under milder conditions, reducing waste generation and energy consumption. This aligns with the current trend in green chemistry, contributing to the development of environmentally friendly synthetic pathways. Apart from reactions initiated with chiral substrates, introducing appropriate chiral factors during the electrochemical process is crucial. In this context, chiral electrodes have garnered significant attention due to their advantages such as high catalytic activity, enantioselectivity, and reusability. This concept aims to introduce the preparation of three main types of chiral electrodes over the past decade, including chiral modified electrodes, chiral immobilized electrodes and chiral imprinted electrodes, and their applications in asymmetric electrosynthesis. The article provides insights into the current state of the field and outlines prospects for future research.

AbstractNear‐infrared (NIR) dyes are desirable for biological imaging applications including photoacoustic (PA) and fluorescence imaging. Nonetheless, current NIR dyes are often plagued by relatively large molecular weights, poor water solubility, and limited photostability. Herein, we provide the first examples of azaphosphinate dyes which display desirable properties such as low molecular weight, absorption/emission above 750 nm, and remarkable water solubility. In PA imaging, an azaphosphinate dye exhibited a 4.1‐fold enhancement in intensity compared to commonly used standards, the ability to multiplex with existing dyes in whole blood, imaging depths of 2.75 cm in a tissue model, and contrast in mice. An improved derivative for fluorescence imaging displayed a >10‐fold reduction in photobleaching in water compared to the FDA‐approved indocyanine green dye and could be visualized in mice. This new dye class provides a robust scaffold for the development of photoacoustic or NIR fluorescence imaging agents.

Published: January 2024

AbstractCompared with Li+, Na+ with a smaller stokes radius has faster de‐solvation kinetics. An electrolyte with ultralow sodium salt (0.3 M NaPF6) is used to reduce the cell cost. However, the organic‐dominated interface, mainly derived from decomposed solvents (SSIP solvation structure), is defective for the long cycling performance of sodium ion batteries. In this work, the simple application of dual additives, including sodium difluoro(oxalato)borate (NaDFOB) and tris(trimethylsilyl)borate (TMSB), is demonstrated to improve the cycling performance of the hard carbon/NaNi1/3Fe1/3Mn1/3O2 cell by constructing interface films on the anode and cathode. A significant improvement on cycling stability has been achieved by incorporating dual additives of NaDFOB and TMSB. Particularly, the capacity retention increased from 17 % (baseline) to 79 % (w/w, 2.0 wt % NaDFOB) and 83 % (w/w, 2.0 wt % NaDFOB and 1.0 wt % TMSB) after 200 cycles at room temperature. Insight into the mechanism of improved interfacial properties between electrodes and electrolyte in ultralow concentration electrolyte has been investigated through a combination of theoretical computation and experimental techniques.

Published: January 2024

AbstractThe methods for the cross‐coupling of aryl(trialkyl)silanes are long‐standing challenges due to the extreme inertness of C−Si(R3) bond, though the reaction is environmentally friendly and highly regioselective to synthesize biaryls. Herein, we report a copper‐catalyzed cross‐coupling of aryl(trialkyl)silanes and aryl via a radical mechanism. The reaction proceeds efficiently with aryl sulfonium salts as limiting reagents, exhibits broad substrate scope, and provides an important synthetic strategy to acquire biaryls, exemplified by unsymmetrical fluorescence probes and late‐stage functionalization of drugs. Of note, the experimental and theoretical mechanistic studies revealed a radical mechanism where the copper catalyst and CsF play critical roles on the radical generation and desilylation process.
