Summary: Understanding the bathymetric patterns of deep-sea meiofauna is essential for understanding the impact of environmental factors on the characteristics of meiofaunal community structures. This study investigated the depth-dependent meiobenthic community structures in the Ulleung Basin in the southeastern East Sea. The results showed significant spatial trends in the distribution of meiobenthic animals, with higher densities on the southern slope of the Ulleung Basin compared to the shelf or deep basin regions. Total organic carbon concentration was found to be significantly correlated with meiobenthic abundance, indicating the importance of food supply in promoting meiofaunal abundance. The study also revealed depth-related trends in meiobenthic community structures, with various taxa contributing to the variations in meiofauna.

Summary: There is a growing demand for modern diagnostic systems for batteries in real-world operation, especially for estimating their health status such as remaining capacity. A data-driven capacity estimation model using recurrent neural networks with long short-term memory capability has been developed for cells under real-world working conditions. This model is robust, can handle input noise, adapt to variations in input time series length, and generate viable estimation even with incomplete input data.

Summary: The nations on the Arabian/Persian Gulf are the largest users of desalination technologies, but concerns have been raised about the long-term effects of increased salinity on marine ecosystems. Current desalinated freshwater production is relatively small, but projections suggest it could reach 10% of net evaporation by the end of the century. However, climate scenarios indicate that increased air temperature and potential changes in precipitation could mitigate the effects of desalination. Additionally, the circulation of high-salinity waters through the Strait of Hormuz limits basin-wide salinity increases.

Summary: Microplastics, the most widespread anthropogenic pollutant in aquatic and terrestrial environments, have large knowledge gaps regarding their origin, fate, and temporal variations in the oceans. This study analyzed sediment trap material from the deep subtropical Northeast Atlantic to assess the role of the deep ocean as a potential sink for microplastics. The study revealed that microplastic particles were present in all analyzed samples, with varying flux rates and mass fluxes among different polymers. The composition of polymers also changed significantly between years, and the correlation between some polymers and lithogenic input suggested an air transport pathway from northeast Africa and surrounding regions.

Summary: The influence of global warming on mid-depth water mass ventilation in the Japan Sea was investigated. The study found a warming trend in the upper portion of the Japan Sea Proper Water (UJSPW) over the past two decades, with higher warming rates in the southern sea compared to the northern sea. The stagnation in the UJSPW formation since the late 1980s resulted in significant changes in mid-depth water mass ventilation in the entire Japan Sea.

Summary: The results suggest that the Arctic Ocean, rather than the Greenland Sea, is the northern terminus of the mean Atlantic Overturning Circulation; open-ocean deep convection, in either the Labrador or Greenland Seas, contributes minimally to the mean Atlantic Overturning Circulation, hence it would not necessarily be substantially weakened by a shutdown of open-ocean deep convection; horizontal circulation across sloping isopycnals contributes substantially (more than 40%) to the maximum mean northeastern subpolar Atlantic Overturning Circulation.

Summary: Marine heterotrophic prokaryotes play a crucial role in degrading and utilizing organic matter in the ocean, with their metabolic rates influenced by various environmental factors. A long-term study in the Gulf of Trieste revealed the strong influence of salinity anomalies on the drivers of heterotrophic carbon production (HCP) rates. Changes in temperature and particulate organic carbon concentration were identified as the main factors impacting HCP rates over different time periods.

Summary: This study proposed a method to determine the background area for each drainage outlet and delineate the mixed surface thermal plumes based on Landsat thermal infrared images. The core surface thermal plumes for 74 drainage outlets of 66 nuclear power plants worldwide were extracted using a deep convolutional neural network. The findings revealed the mean maximal water surface temperature increment and identified the nuclear power plants with the highest increases and largest thermal-polluted surface area. The dataset provided can describe the long-term occurrence of water surface thermal plumes. Three influencing factors of the water surface thermal plume were analyzed, and the proposed method provides a framework for future detection using remote sensing and deep learning.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
