Summary: The flower-shaped Bi2S3/g-C3N4-2.6 heterojunction obtained by solvothermal method exhibited high photocatalytic degradation efficiency for rhodamine B and tetracycline, with removal rates of 98.8% and 94.6% within 40 minutes, respectively. The photocatalytic reaction rate constant of Bi2S3/g-C3N4-2.6 was significantly higher than that of Bi2S3 and g-C3N4, indicating the importance of the heterojunction in accelerating electron transfer and avoiding electron-hole recombination. The study also investigated the effects of catalyst dosage, pH values, inorganic anions, and capture agents on the photodegradation performance of rhodamine B.

Summary: Researchers developed a flower-like Co-Mo2C sphere/g-C3N4 heterostructure photocatalyst derived from biochar for the degradation of pharmaceuticals and personal care products (PPCPs). The sharp-edged open-up nanoflake structure allowed for fast charge collection and separation. DFT calculations and experimental characterizations revealed the enhanced intrinsic photocatalytic activity of the catalysts, particularly the role of Co atoms. The Co-Mo2C nanoflower catalyst displayed superior photocatalytic activity compared to the Mo2C/g-C3N4 bulk due to its multifaceted open-up surfaces, higher electron density, more efficient charge transfer ability, and prolonged lifetime of photogenerated charge carriers.

Summary: Research on the nature of nonoscillatory electrophysiological activity similar to 1/f has grown rapidly in cognitive neuroscience. This type of activity, which is linked to the balance between excitatory and inhibitory neural circuits, is crucial for information processing. A study analyzing human EEG data found significant differences in the post-event spectra compared to the pre-event spectra, even after removing the frequency-content of event-related potentials (ERPs). This difference is related to an increase in inhibition and a disruption of ongoing excitatory activity following stimulus onset, proportional to the attentional demands of the task. These findings have important implications for various subfields of neuroscience.

Summary: In this study, we identified a new gene OsHIPL1 as a causal gene for rice seed vigour. Our findings suggest that OsHIPL1 regulates seed vigour in rice by modulating endogenous ABA levels and altering the expression of ABA-related genes. Furthermore, we found that OsHIPL1 interacts with the aquaporin OsPIP1;1, affecting water uptake and promoting rice seed germination.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
