Summary: A nanoscale Li-O-2 nanobattery was assembled in an aberration-corrected environmental transmission electron microscope (ETEM) to track the catalytic mechanism of silver (Ag) catalyst during the charge/discharge process. It was found that numerous Ag nanoparticles were observed on the surface of Ag nanowire, which acted as catalysts for subsequent reactions. By synthesizing Ag nanoparticles decorated on porous carbon, the cycling stability and maximum specific capacity of Li-O-2 battery were improved. This study suggests that nanoscale Ag may be a promising catalyst for Li-O-2 battery.

Summary: First-principles calculations were performed to investigate WN MXenes as potential cathode catalysts for Li-O-2 batteries. The results show that the oxygen functionalized surfaces of WN MXenes can lower the overpotentials of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) due to their ability to bind with Li and promote electron transfer. Reducing the atomic layers of WN MXenes can further lower the overpotentials.

Summary: A bi-functional catalytic perovskite LaNi0.5Co0.5O3 (LNCO) is utilized as the cathode in a high-efficiency Li-O2 battery with a molten nitrate salt electrolyte at 160 degrees C. This LNCO cathode exhibits stable low charge-discharge overpotential and high energy efficiency over 100 cycles. The discharge product, Li2O, has a porous and fluffy morphology, facilitating the transfer of oxygen and other intermediate species. Li2O as a discharge product enables a higher theoretical specific energy density compared to Li2O2 in ambient temperature Li-O2 batteries.

Summary: This study investigated the changes in microstructure and grain orientation of the Cu3Sn solder joint during isothermal aging at 420 degrees C. It was found that the original Cu3Sn solder joint transformed into full Cu(41)Sn(11) solder joint and eventually into full alpha(Cu) solder joint during aging. The formation of micro-voids during the conversion process resulted in lower reliability of the solder joint. The average grain sizes of interfacial phases exhibited an initial increase followed by a decrease during aging. The preferred orientations of the different phases were also examined.

Summary: Wastewater contaminated by radionuclides is a significant environmental concern that poses a threat to human health. In this study, beta-cyclodextrin modified molybdenum disulfide was investigated as an adsorbent to remove europium from aqueous solutions. The experimental results indicated that the adsorption of Europium(III) relied on pH and temperature. The Langmuir model better described the removal process, which was found to be a monolayer adsorption. The adsorption capacity of beta-CD-MoS2 for Europium(III) reached 107.1 mg/g and the adsorption process was endothermic. The surface hydroxyl groups controlled the retention of Europium(III). These findings provide important information for environmental pollution control and the elimination of Europium(III).

Summary: This study conducted a comprehensive genome-wide analysis of the bZIP gene family (RcbZIPs) in rose, revealing their phylogenetic relationships, gene structure, chromosome localizations, gene duplication, and potential functions. The expression analysis showed significant differential expression of 16 RcbZIPs in response to Botrytis cinerea infection, suggesting their candidate role in regulating rose's response to gray mold infection. Virus-induced gene silencing (VIGS) and overexpression (OE) studies demonstrated the involvement of RcbZIP17 in rose's resistance to gray mold. This study provides valuable information for further investigation into the function of the bZIP gene family in rose.

Summary: This study proposes a water resource pollution load intensity measurement based on the SWAT model, aiming to solve the problems of high measurement time-consuming, high deviation, and small area in traditional methods. The method involves building a basic database, summarizing hydrological characteristic data, designing a water pollution output coefficient model using the SWAT model, and using the comprehensive pollution index method to measure the pollution load intensity of water resources. The experimental results demonstrate that this method reduces measurement time, improves measurement accuracy, and expands the measurable area.
