Summary: By using a chiral molecular gelation system with a carboxylic acid functional group, enantioselectivity was effectively induced by forming highly ordered aggregates with negatively charged surfaces for carboxyl groups to assemble in highly ordered states and attaching the cationic groups of the guest molecule to this surface through multiple interactions.

Summary: Non-fullerene acceptor (NFA)-based organic solar cells have shown significant progress in recent years. The choice of solvent for spin coating the active layers affects the film morphology and crystallinity. Among the compared chlorinated solvents (CB, chloroform, and dichlorobenzene), CB offers the best combination of small domain sizes, high number of edge-on crystallites, and small distances between neighboring domains. The smooth blend films obtained with CB have correlated roughness with the substrates and no large aggregates, leading to the highest power conversion efficiencies (PCEs).

Summary: This paper investigates the bearing-based formation tracking control problem of multiple autonomous underwater vehicles (AUVs) with consideration of linear velocity and actuator constraints. A leader-follower structure is adopted, where the leaders' motion is characterized by a time-varying and unknown linear velocity. Consensus-based orientation estimator and adaptation law for estimating leaders' linear velocity are proposed. A bearing-based formation tracking controller is designed for the followers to achieve the desired formation shape. The global asymptotic stability of the overall system is analyzed using cascade system theories. The gains of the estimator and controller are determined by an optimal gains tuning method.

Summary: The design and synthesis of rosin-based sulfonamide compounds with controllable weak forces is important for solving industrial problems. In this study, three such compounds were designed and formed different morphologies of organogels. The organogels successfully captured volatile organic solvents and formed stable supermolecular assemblies through the presence of conjugation. Among them, DBS-1 exhibited remarkable anti-settling ability in synthetic oil-based drilling fluids.

Summary: This study constructed a TP-loaded beeswax gelator to improve the oxidative stability of oleogels in soybean oil. The TP improved dispersity in lipids and inhibited lipid oxidation without participating in the internal network structure of the oleogel. The formation of needle-like crystals by beeswax restricted liquid oil flow, leading to a significant decrease in peroxide value during storage.
