Published: August 2024

AbstractUrea plays a crucial role in agricultural production; however, issues of misuse and low utilization persist. To address this, a poly(vinyl alcohol) (PVA) modified metal–phenolic networks (MPNs) coating was developed to enable the slow release of urea. The coating formulations involved blending tannic acid (TA) and Fe3+ at different molar ratio, along with varying amount of PVA. The resulting TA‐Fe3+‐PVA coating with a 1:3 molar ratio of TA:Fe3+ and 1 mg/mL of PVA formulation exhibited stable and dense properties. Urea granules were then coated with this formulation using a fluidized bed technique, leading to reduction in nutrient release rate and increase in longevity. Especially, the nutrient release rate was approximately 10 days in soil. Pot experiments confirmed that the coated urea effectively enhanced cotton yield and quality. Therefore, the newly developed TA‐Fe3+‐PVA coated urea shows promising potential in agriculture for maintaining yield while reducing urea application amounts in the future.

AbstractPeirosauridae (Crocodyliformes, Notosuchia) is one of the fossil lineages of crocodyliforms ubiquitous in the Cretaceous deposits of the Bauru Basin. Here, we describe a new species of a longirostrine Peirosauridae from the Adamantina Formation (Bauru Basin, Late Cretaceous). The specimen consists of a partially preserved skull with a cranial roof, interorbital region, and fragments of the posterior portion of the rostrum, including the prefrontal and lacrimal; left hemimandible, with 14 alveoli and 12 teeth; and a single cervical rib fragment. The specimen is associated with Peirosauridae by three cranial synapomorphies, and it can be assigned to a new genus and species by presenting seven cranial and one tooth apomorphies. To clarify the position of the new taxon, an updated phylogenetic analysis was performed with increased sampling of taxa of Notosuchia, especially Peirosauridae, and phylogenetically relevant characters. Our results indicated the monophyly of Peirosauridae, formed by two main lineages, the oreinirostral and presumably terrestrial Peirosaurinae and the longirostrine and presumably semi‐aquatic Pepesuchinae. The recovering of both lineages as distinct entities was also reinforced through a morphospace analysis. Pepesuchinae were notable by exploring a position of the morphospace not explored by any other Notosuchia. Their longer rostra and the assumption of them being gradually specialized to aquatic habits reflects the unique diversity of these crocodyliforms through the Cretaceous deposits of South America and Africa.

Published: August 2024

AbstractHigh‐efficiency quantum dot sensitized solar cells (QDSSCs) can be received by increasing quantum dot (QD) loading and mitigating QD surface trap states. Herein, the surface state of CuInS2 QDs is optimized through an I−/MPA dual‐ligands passivation strategy. The steric hindrance and electrostatic repulsion between QDs can be effectively reduced, thereby enabling an increased QD loading capacity. Meanwhile, the I−/MPA dual‐ligands passivation strategy can further lower the surface trap density, leading to substantially enhanced charge transfer efficiency of the solar cells. Interestingly, various iodized salts, including TBAI, MAI, and KI, are proved to possess comparable property, underscoring the versatility and broad applicability of this I−/MPA dual‐ligands passivation strategy. Eventually, CuInS2 QDSSCs based on the NH4I/MPA dual‐ligands exhibit a noteworthy enhancement in photovoltaic conversion efficiency, surpassing the benchmark of 5.71 % to reach 7.03 %.

AbstractPurposeThis study aimed to report a newly developed, high‐fidelity synthetic simulator to simulate excision and primary anastomotic (EPA) bulbar urethroplasty and its clinical use for new practitioners in shortening the learning curve.Material and MethodsThe bulbar urethral anastomosis simulator consists of several standardized components created according to the actual size of the male patient. Interns, novice residents, and fellows inexperienced with urethral reconstruction (n = 10, 5, 5) from different medical centres were invited to participate in the training programme. Two reconstructive urology experts monitored each practice. Following the training, three kinds of validity testing were used to assess the simulator: face, content, and construct. In the intern group, the task performance in the first five training sessions and the last five training ones were compared using a self‐control approach. In the resident and fellow group, the real surgical data, including estimated blood loss, operative duration, and 6‐month post‐operative success rate of trainees after training, are plotted, which are compared with that of reconstructive urology experts (n = 5) included retrospectively to study the effectiveness of the simulator in shortening the learning curve.ResultsThe overall mean satisfaction rate for the simulators was inspiring and evaluated by experts. In the intern group, significant improvement can be achieved through 10 training sessions (p < 0.05). In clinical practice, the intraoperative indicators and surgical success rate of both the training groups showed the tendency to close or even better than those in the expert group. In terms of the learning curve, training groups performed better compared with experts in the early stages of their careers.ConclusionsIn conclusion, this synthetic training simulator for bulbar urethral anastomosis is novel, effective, and convenient for beginners of different groups. The training course can bridge the gap between preclinical use and actual surgery via this simulator.

AbstractThe mutual interactions of endoplasmic reticulum (ER) resident proteins in the ER maintain its functions, prompting the protein folding, modification, and transportation. Here, a new method, named YST‐PPI (YESS‐based Split fast TEV protease system for Protein‐Protein Interaction) was developed, targeting the characterization of protein interactions in ER. YST‐PPI method integrated the YESS system, split‐TEV technology, and endoplasmic reticulum retention signal peptide (ERS) to provide an effective strategy for studying ER in situ PPIs in a fast and quantitative manner. The interactions among 15 ER‐resident proteins, most being identified molecular chaperones, of S. cerevisiae were explored using the YST‐PPI system, and their interaction network map was constructed, in which more than 74 interacting resident protein pairs were identified. Our studies also showed that Lhs1p plays a critical role in regulating the interactions of most of the ER‐resident proteins, except the Sil1p, indicating its potential role in controlling the ER molecular chaperones. Moreover, the mutual interaction revealed by our studies further confirmed that the ER‐resident proteins perform their functions in a cooperative way and a multimer complex might be formed during the process.

AbstractCO2 electrochemical reduction (CO2ER) powered by renewable electricity is critical for transitioning to a carbon‐neutral society by transforming CO2 into essential commodities and fuels. The formation of multi‐carbon compounds through C−C coupling reactions is crucial due to their high energy density and broad industrial uses. Traditionally, C−C coupling was believed to occur through the reaction of *CO (surface‐bound CO) with *C1 intermediates (surface‐bound hydrocarbons with one carbon atom produced during CO2ER). In this study, we used DFT calculations combined with a constant electrode potential model to discover a preference for CO2+*C1 over conventional *CO+*C1 coupling on three commonly observed copper surfaces including Cu(111), Cu(110), and Cu(100). This result demonstrates that CO2 is a more efficient carbon source than *CO for coupling with *C1. Among the nine *C1 species investigated, *CHO, *CHOH, *C, *CH, and *CH2 show greater reactivity towards CO2+*C1 couplings on all the surfaces. Thus, enhancing CO2ER efficiency necessitates increasing the surface concentrations of these five *C1 intermediates, and several strategies have been proposed to accomplish this goal.

Published: August 2024

AbstractThe much‐needed global shift from fossil fuels to sustainable energy is driving significant attention towards hydrogen (H2) as a promising alternative. Proton reduction, a process central to H2 production, is a key area of research for this transition. Naturally‐occurring [FeFe] and [NiFe]‐hydrogenase enzymes play vital roles in the reversible production and oxidation of H2. These enzymes feature a proton‐relay unit comprising of pendant amine and thiol groups in the secondary coordination sphere at the active site. This unit accelerates the rate of H2 production/oxidation, making it a focal point for scientific exploration. Efforts are concentrated on mimicking the active sites of these enzymes both structurally and functionally. In this pursuit, many synthetic transition metal complexes with proton‐responsive units at the secondary coordination sphere of the active site mimic the enzyme's behavior. These units facilitate intramolecular metal‐hydride (M−H) generation and H2‐elimination via H+/H−s coupling, leveraging the proton from the pendant functional group and the hydride from the M−H intermediate. This review delves into electrocatalysts featuring pendant proton‐responsive units and their roles in the electrochemical hydrogen evolution reaction (eHER).

Published: August 2024

AbstractSeveral complexes of the intramolecular frustrated Lewis pair (FLP)‐supported P(−1) ligand [iPr2P(C6H4)BCy2{P}]− are presented (Cy=cyclohexyl). Chief among these is the first example of a monomeric zinc bis(phosphido) complex, which was synthesized as a potential precursor for the solution‐phase deposition of Zn3P2. While this goal was ultimately unsuccessful, the Zn(II) complex acts as a convenient springboard to other metal phosphide species via transmetallation: affording a tellurium bis(phosphido) complex and a formal adduct of the phosphorus subhalide PPCl2. Trapping experiments show that the PPCl2 adduct can also be prepared directly through the in situ reduction of PCl3 in the presence of an intramolecular FLP ligand. Lastly, we report a formal η2‐phosphaborene complex of cobalt(−1) which is isoelectronic to olefin complexes, and explore its bonding via density functional theory (DFT) computations.

Published: August 2024

AbstractConventional routes for the production of formaldehyde rely on the use of methanol and air, with the presence of catalysts such as silver or mixed‐metal oxides. These processes are highly energy intensive and therefore raise concerns in terms of cost‐effectiveness and environmental impact. In that respect, sodium or sodium compounds are more favorable as catalysts for the direct dehydrogenation of methanol to water‐free formaldehyde. A method is presented for the coproduction of hydrogen and anhydrous formaldehyde – both valuable products – on the laboratory scale, with a particular focus on the design and testing of a sodium vapor catalyst dosing unit that enables the process to be performed continuously.

Published: August 2024

AbstractThe study explores air separation processes, proposing an innovative design incorporating liquid natural gas (LNG)'s two‐stage Rankine cycles to address traditional approaches' complexity and energy intensity. Significant wastage of energy during air compression in standard units is recuperated for liquefied natural gas regasification, with a focus on enhancing cold energy recovery, emphasizing cryogenic LNG advantages. Aspen HYSYS (12.1) is used for process modelling and simulation evaluating a combined two‐stage Rankine cycle integrated into air separation. Specific energy requirements for high‐purity oxygen and nitrogen production are reduced to 0.38 and 0.12 kWh/kg, respectively. The integrated Rankine cycle generates 4456.32 kW, which is sufficient for air separation process. Exergy destruction and component efficiency are explored and parametric optimization, revealing LNG variables' significant impact. Economic analysis indicates a fair 5.25‐year payback period. This approach aligns with sustainability goals, providing a compelling efficiency‐enhancing option for the LNG sector.
A semi‐automatic method for block‐structured hexahedral meshing of aortic dissections

Published: August 2024

AbstractThe article presents a semi‐automatic approach to generating structured hexahedral meshes of patient‐specific aortas ailed by aortic dissection. The condition manifests itself as a formation of two blood flow channels in the aorta, as a result of a tear in the inner layers of the aortic wall. Subsequently, the morphology of the aorta is greatly impacted, making the task of domain discretization highly challenging. The meshing algorithm presented herein is automatic for the individual lumina, whereas the tears require user interaction. Starting from an input (triangle) surface mesh, we construct an implicit surface representation as well as a topological skeleton, which provides a basis for the generation of a block‐structure. Thereafter, the mesh generation is performed via transfinite maps. The meshes are structured and fully hexahedral, exhibit good quality and reliably match the original surface. As they are generated with computational fluid dynamics in mind, a fluid flow simulation is performed to verify their usefulness. Moreover, since the approach is based on valid block‐structures, the meshes can be made very coarse (around 1000 elements for an entire aortic dissection domain), and thus promote using solvers based on the geometric multigrid method, which is typically reliant on the presence of a hierarchy of coarser meshes.

AbstractThe public pay special attention on the disclosure of corporate social responsibility (CSR) nowadays, and how to improve the quality of corporate social responsibility information disclosure and analyze its influencing factors has been the focus of theoretical and practical circles. This study aims to analyze how the information interactions on social media platform affect CSR disclosure quality by using the data of East Money Guba Stock Forum from 2010 to 2021 in China. This paper shows that the information interactions from investors on social media platform can significantly improve the CSR disclosure quality. The result is more pronounced when the online information topics were related with CSR and contained negative sentiment. In addition, we found that the positive relationship between information interactions and CSR disclosure quality is positively moderated by market competition and managerial shareholder, however, the positive relationship is weakened in state‐owned enterprises (SOEs). These findings are robust to using alternative tests. Finally, our analysis confirms that social media information interactions affect CSR disclosure quality by improving information disclosure and corporate governance quality. This study enriches the relevant literature on the economic consequences of social media in emerging markets and provides relevant implications to better drive the CSR disclosure of enterprises. These findings have important implications for policymakers.

Published: August 2024

AbstractLi‐CO2 batteries have been recognized as an emerging technology for energy storage systems owing to their high theoretical specific energy and environmentally friendly CO2 fixation ability. However, their development for applications requires a high energy efficiency and long cycle‐life, this is currently limited to the formation of wide‐bandgap insulator Li2CO3 during discharge. Here, nanoparticle Pd supported on reduced graphene oxide (rGO) is utilized as cathodes for Li‐CO2 batteries, Pd nanoparticles as active centers significantly enhance CO2RR/CO2ER reaction activity, which can support the fast formation and decomposition of Li2CO3 in organic electrolytes and achieve a high discharge capacity of 7500 mAh g−1. It also performs remarkably high cycling stability of over 500 cycles with a long cycle‐life of 5000 hours. The observed super electrochemical performance is attributable to the thick electrode design and uniform distribution of ultrafine catalyst nanoparticle Pd. When Li2CO3 is adsorbed on Pd particle, the Li−O bond in Li2CO3 will be elongated due to the interactions of two nucleophilic O atoms with Pd, resulting in a weakening of the Li−O bond and activation of Li2CO3. Our work suggests a way to design catalysts with high activity that can be used to activate the performance of Li‐CO2 batteries.

AbstractAs the demand for polycarbonate (PC) plastic increases over the years, the development of a chemical recycling system to produce virgin‐like‐quality monomers is indispensable not only to attain completely sustainable cycles but also to contribute to the decrease in global plastic pollution. Herein, potassium carbonate (K2CO3) was used as a low‐cost, readily available, and highly active solid base catalyst for low‐temperature PC methanolysis in the presence of THF as a solvent, producing highly pure and crystalline bisphenol A (BPA) and with a catalytic performance higher than group IIA metal oxides (MgO, CaO, and SrO) and some group IA metal carbonates (NaHCO3, KHCO3, and Na2CO3). THF was the best solvent in aiding the reaction owing to it having a similar polar parameter (δp) to that of PC according to Hansen solubility parameters. By the reaction over the catalyst, 100% PC conversion, 97% BPA yield, and 86% dimethyl carbonate yield were achieved within just 20 min at 60 °C. The catalyst possessed an apparent activation energy (Ea) of 52.3 kJ mol−1, which is the lowest value so far for heterogeneous catalysts, while the mechanistic study revealed that the reaction proceeded via the methoxide pathway. The reusability test demonstrated that the catalyst was reusable at least four times. Furthermore, this catalytic system was successfully applied to actual post‐consumer PC wastes and polyesters, including polyethylene terephthalate (PET) and polylactic acid (PLA).
