Summary: This study investigates the synthesis and applications of magnetite nanorods (MNRs) in magnetic hyperthermia, photothermia, and drug release. The results show that the MNRs exhibit high monodispersity and consistent shape, and their photothermia response can be improved by controlling the parameters of external fields. By coating the MNRs with a layer of gold and polyethyleneimine (PEI), the efficiency of MNRs in magnetic hyperthermia and photothermia treatments can be enhanced. Furthermore, the study confirms the non-cytotoxicity of MNRs to human cells and demonstrates their ability to release drugs at a faster rate.

Summary: In this research, a strong hygrothermic wood actuator with asymmetric water affinity is designed to overcome the challenges of poor mechanical performance, complicated fabrication processes, and the inability to complex deformation. The actuator is constructed by sandwiching polypyrrole-coated wood with a Ni complex hygroscopic gel top layer for moisture absorption and a polyimide bottom layer as the water barrier. It can stretch and bend itself in response to moisture and thermal/light stimulation. Experimental results show that the hygrothermic wood actuator can demonstrate dexterous object-hand interactions and has the potential to be applied in fire rescue scenarios. This actuator simultaneously realizes good mechanical properties, multi-stimulus-responses, complex deformation, a wide working temperature range, low manufacturing cost, and biocompatibility, opening up a new avenue for building intelligent robotic hand systems.

Summary: In this study, a low-cost and highly efficient bimetallic Cu-Co oxide/oxyhydroxide electrocatalyst (CuOCoOOH) was developed for synthesizing bio-based carboxylic acids. The incorporation of Cu in CuOCoOOH improved substrate absorption, defect construction, and the formation of high valence active species, leading to significant enhancement in the catalyst's electrooxidation performance. The electrooxidation of 5-hydroxymethylfurfural with CuOCoOOH achieved a high yield (98%) of 2,5-furandicarboxylic acid with a Faradaic efficiency of 98%. Density functional theory calculations demonstrated the effectiveness of CuOCoOOH in substrate adsorption and oxygen vacancy formation for improving electrooxidation performance. Additionally, 12 carboxylic acids were successfully produced from bio-based alcohols/aldehydes with excellent yields of 96.4-99%.
