Summary: This study investigated the spatiotemporal dynamics of soil moisture and salinity in a reclaimed wetland park in Guangdong Province, China. The results showed that diel evaporation influenced soil water up to a depth of 40 cm, while extreme rainfall only increased topsoil moisture without significant effects on soil salinity. Salt accumulation occurred at depths between 40 and 70 cm during the rainy season, persisting until the end of the monitoring period. In the dry season, the topsoil became salinized up to a depth of 30 cm, but recovered after rainfall.

Summary: Long-term soil salinization leads to soil hardness, nutrient imbalance, and reduced microbial diversity, resulting in low rice yields. This study examined the effects of biofertilizer based on halotolerant microorganisms on rice growth and saline stress in salinized soil. The results showed that biofertilizer significantly increased soil nutrient availability and rice yield, while reducing soil electrical conductivity. Biofertilizer also improved soil microbial diversity and community structure. Moreover, it was found that available phosphorus and cation exchange capacity were key factors affecting microbial community structure. The application of biofertilizer showed potential for alleviating rice growth stress and improving nutrient supply in saline soil.

Summary: Monitoring and mapping soil salinity is valuable for irrigation management and reclamation of salt-affected agricultural soils. Proximal measurements of apparent soil electrical conductivity can help characterize soil salinity distributions, but ECa is also influenced by water content and soil properties. The study evaluated protocols for using proximal ECa sensing in drip irrigated systems, focusing on identifying areas of high salinity in the rootzone.

Summary: Silicon suboxides (SiOx) are potential anode materials for high-energy lithium-ion batteries (LIBs) due to their high specific capacity and stable cycling performance. The crystallinity of Si embedded in the SiO2 matrix significantly influences the electrochemical performance of SiOx. The presence of heat absorbents (KCl and NaCl) during the magnesiothermic reduction of SiO affects the crystallinity of SiOx particles and hence the electrochemical behavior of SiOx during cycling, with KCl leading to superior performance compared to NaCl.

Summary: F-containing functional electrolytes are investigated to improve the performance of Li-metal batteries by generating stable LiF-based solid-electrolyte interphase layers. However, these electrolytes corrode both the Al current collector and the stainless steel (SS) component of the coin cell at high voltages. This study finds that SS corrosion has a greater effect on capacity fading than the Al case, and proposes SS and Al-free pouch-type cells with carbon current collectors and locally high-concentration electrolyte to develop stable cells.

Summary: Lithium-sulfur (Li-S) batteries are considered as promising energy storage devices for portable electronics and electric vehicles due to their low-cost, high-energy density, and minimal environmental impact. However, the low sulfur utilization and short lifespan hinder their performance and commercialization. In this study, Li-S battery cathodes were prepared by blending sulfur (S) with modified multiwall carbon nanotubes (MWCNTs) and poly (acrylic acid) (PAA) as a binder to optimize the electrode composition. The cathode prepared with a 5:4:1 wt ratio of S:oxidized MWCNT:PAA showed the highest discharge capacity of approximately 480 mA h g-1. This work demonstrates the feasibility of using redox mediation to enhance electron accessibility with sulfur loaded on MWCNT.

Summary: During the growth of anodic TiO2 nanotubes with a high layer thickness, nanograss structures are formed on the outermost surface through engraving of the oxide tubes in an F- ion containing electrolyte. These nanotubular layers have a high aspect ratio with bundles of nanograss structures on the tube top and high surface area with anatase crystallites inside. By combining two-step anodization and a rubber polymer binder, freestanding nanotubular layers with nanograssy surfaces and nano-crystalline particles in the tubes were obtained. This nanotubular hybrid membrane exhibited excellent performance in Li-S batteries, delivering a capacity of 618 mA h g(-1) after 100 cycles at 0.1C, thanks to efficient polysulfide trapping and electrolyte perturbation.
