Summary: Fast and accurate prediction of regioselectivity is important in reducing time and resources spent on unproductive transformations in the pharmaceutical industry. We introduce a prototype that combines machine learning and transition state theory modeling, by triggering resource-intensive calculations only on less confident ML predictions. The proposed workflow achieves high accuracy on both internal and public datasets, in a fraction of the time compared to conventional methods.

Summary: This study compared tree dating methods based on substitution rates with those using fossil data to analyze the evolutionary history of New Zealand endemic Berosus water beetles. Results showed that the substitution rate method underestimated the origin and evolution of the species, while analyses incorporating fossil data provided significantly older age estimates, indicating an early Cenozoic origin for the New Zealand clade. Strong variation in substitution rates among Coleoptera lineages and within the family Hydrophilidae was identified as the main reason for the low accuracy of rate-calibrated analyses in this study. The researchers provided evidence that events from the Oligocene to Pliocene were more crucial in shaping the modern New Zealand insect fauna than the Pleistocene Glacial cycles.

Summary: Industry has been increasingly adopting Convolutional Neural Networks (CNNs) in applications ranging from IoT to autonomous driving. Convolutional hardware accelerators are preferred over CPUs and GPUs for the inference phase due to their smaller power consumption and improved performance. However, there is a lack of comprehensive evaluation in the literature regarding different 2D architectures used in these accelerators and their suitability based on design constraints and memory type (SRAM or DRAM). Experiments demonstrate that WS accelerators have the smallest area and energy consumption when using SRAM, while IS accelerators deliver the best performance. Conversely, IS accelerators show reduced performance sensitivity to memory latency when using DRAM.

Summary: The structure, spectroscopy, and photochemistry of two compounds, 4-azidobenzoic acid (4ABC) and 4-azido-2,3,5,6-tetrafluorobenzoic acid (4F4ABC), were characterized in frozen glasses and crystals. Photolysis of the parent compounds produced nitrenes and other spin species, with higher yield of triplet nitrene in 4F4ABC and higher yield of quintet nitrene in 4ABC. The stability of the nitrene in the 4F4ABC crystal, with a 1/e lifetime of 20 days at room temperature, provides potential for creating stable, solid-state nitrene samples for applications in spintronics and quantum information science.

Summary: Electrochemical reduction of CO2 (CO2RR) and nitrogen (NRR) has potential as an alternative to fossil fuel-based technologies for producing valuable chemicals. However, the low energy and Faradaic efficiencies hinder their practical application, despite efforts to overcome these limitations. This review focuses on the different electrolytes used in CO2RR and NRR, including aqueous and non-aqueous electrolytes such as acidic, neutral, alkaline, water-in-salt, organic, and ionic-liquids electrolytes. The roles of these electrolytes and their potential for improving electrocatalytic performance are discussed, with suggestions for future research priorities to enhance understanding and guide selection for next-generation gas-involved electrochemical reactions.

Summary: Multidimensional hierarchical hollow Co3O4/ZnIn2S4 tubular core-shell heterostructures were prepared by growing ultrathin 2D ZnIn2S4 nanosheets on 1D hollow Co3O4 nanotubes using a solvothermal method. This design not only prevents the self-assembly aggregation of ZnIn2S4 nanosheets, but also broadens their light-absorption range and enhances the utilization of visible light. The p-n heterojunction in the photocatalyst generates an internal electric field, which facilitates the separation and migration of photogenerated charge carriers and effectively suppresses their recombination.

Summary: A simple hydrothermal method was reported to fabricate novel heterostructure nanoarrays comprising NiSe nanorods evenly integrated with nickel-terephthalic acid (Ni-TPA) nanosheets. In the A-C heterostructure electrocatalyst, highly conductive NiSe nanorods facilitate axial charge transfer in the interconnection network. TPA-induced formation of crystalline-amorphous heterostructures exposes more active sites and regulates the electronic structure of Ni. The optimal Ni-TPA@NiSe/NF electrode presents a low potential of 1.37 V to deliver 100 mA cm-2 for UOR while maintaining impressively robust stability at high current densities for at least 40 h. In situ electrochemical Raman spectroscopy and differential electrochemical mass spectrometry analyses reveal that the superior UOR activity originates from NiOOH species and the terminal product of nitrogen is generated via intramolecular N-N coupling in the urea molecule. More importantly, this study offers deep insights into designing and fabricating effective UOR electrocatalysts with abundant A-C grain boundaries.

Summary: In this study, self-assembled monolayers (SAMs) were constructed on the surface of Ti3C2 MXene to improve its environmental stability and piezocatalytic activity. The surface-treated Ti3C2 exhibits different lattice parameters and symmetry, leading to an increased polarization. The presence of polar functional groups in SAMs significantly increases the surface potential of Ti3C2, promoting the migration of piezoelectric electrons. Among the different SAMs, Ti3C2/SAMs-NH2 shows the highest piezocatalytic performance, improving the removal of BPA and the production of H-2 by 7 and 1.8 times, respectively, and remains stable under 100% relative humidity for 15 days.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
