Summary: Understanding the structure evolution of lignite during depolymerization is crucial. This study investigated the structural changes of lignite during ruthenium ion catalytic oxidation (RICO) depolymerization. It was found that lignite transformed from microparticles to nanoparticles during depolymerization, which further released soluble products into the solution. The molecular weight of the soluble products had a wide distribution, indicating the gradual decomposition of macromolecules from lignite particles. These findings provide insights into the depolymerization process of lignite and are valuable for its regulation and control.

Summary: Understanding the behavior of heavy metals in the environment through humic acid (HA) is crucial, but there is a lack of knowledge on the control of HA's structure organization and its reactivity. This study used the fractionation method to reduce the heterogeneity of HA and analyzed its chemical properties. The results showed that the adsorption capacity for lead ions (Pb2+) followed the order of HA-1 > HA-2 > HA-3. Linear analysis indicated that the adsorption capacity was positively correlated with acid groups, carboxyl groups, phenolic hydroxyl groups, and the number of aliphatic chains. Structural differences and the number of active sites play an important role in adsorption.

Summary: Amylose content (AC) is influenced by the Waxy (Wx) gene, and OsEBP89, OsBP5, and OsSK41 play important roles in its regulation. OsSK41 phosphorylates OsEBP89, leading to its instability and reduced interaction with OsBP5, resulting in increased AC. In contrast, loss of OsEBP89 function reduces Wx expression and decreases AC. These findings provide potential targets for gene editing to regulate AC in rice grains.

Summary: This study systematically investigates the dynamic response of windmill-like star-hexagon (WSH) honeycombs through theoretical calculations, numerical simulations, and experimental methods. The static and dynamic plateau stresses of WSH honeycombs are calculated, and critical velocities leading to different deformation modes are determined. Furthermore, the gradient design of WSH honeycombs is analyzed, and the energy absorption performance of gradient WSH honeycombs is explored through numerical simulations. It is found that WSH honeycombs exhibit better energy absorption capacity than conventional honeycombs under low-velocity impact loading, and the concave angle gradient design and thickness gradient design can further enhance their energy absorption performance.

This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.
