Summary: In this study, thermoresponsive single-layer hydrogel actuators with tunable bending properties were produced by generating a gradient distribution of cellulose nanocrystals (CNCs) in a poly(N-isopropylacrylamide) (PNIPAAm) hydrogel network by electrophoresis. By varying electrophoresis time, applied voltage, and CNC concentration, the bending properties of the composite hydrogels, including thermoresponsive bending speed and angle, can be adjusted. The bending ability of the hydrogels is attributed to the gradient distribution of CNCs causing different deswelling rates across the hydrogel network and is influenced by differences in CNC dimensions.

Summary: Various dimensional nanostructures of CuTCPP were successfully constructed via liquid-phase chemical methods, and their photoelectric properties were investigated to evaluate the effect of shape, size, and structure. Significant differences in photocurrent response were found among the different nanostructures, with 1D nanostructures exhibiting the lowest impedance and longest exciton lifetime, indicating that the photocurrent of metal porphyrin nanostructures is mainly limited by in-plane excitons. This work provides a clear strategy for designing molecule-based photoelectric nanomaterials.

Summary: Carbon materials are considered promising anode candidates for sodium-ion batteries (SIBs) due to their high conductivity and wide availability. However, their practical application is limited by their lower capacitance and restricted interlayer spacing. In this study, an atom-adjustable doping strategy was used to fabricate N/P dual-doped porous carbon nanosheet anodes (NP-PCN) via in situ pyrolysis of supermolecules. The resulting NP-PCN exhibited enhanced reversible capacity, robust rate capability, and long cycle life. The study also explored the storage mechanism and may inspire the design of high-performance carbon anodes for rechargeable alkali-metal-ion batteries at an atomic level.

Summary: Co-free high-Ni layered transition metal oxide is a promising cathode material for Li-ion batteries, but its rate performance and capacity decay during high-rate cycling are problematic. This study reveals the atomic scale structural changes of Co-free high-Ni layered cathode under different cycling rates using advanced TEM characterization. The structural evolutions after high-rate cycling are different from those after low-rate cycling, showing severe lattice distortion and structural dislocations. These findings deepen the understanding of the rate-dependent structural degradation mechanism and have implications for improving cathode materials for high-rate applications.

Summary: A new micro/mini-channel heat sink (MCHS) with a combined structure of longitudinal and transverse vortex generators is designed, using Al2O3 nanofluid as the working medium. The study explores the effects of transverse vortex generator shape and longitudinal vortex generator angle on the hydraulic and thermal characteristics, comprehensive performance, entropy generation, and exergy efficiency. The results show that the triangular transverse vortex generator improves the comprehensive performance and exergy efficiency. Combined with the longitudinal vortex generator, the MCHS achieves the best comprehensive performance, entropy generation, and exergy efficiency when the Reynolds number is 742.

Summary: Fluidization at low pressure offers significant benefits for the fine chemical industry. This study investigates the behavior of bubbles and bed expansion under low pressure conditions. It is found that lower pressure leads to larger bubbles, increased bubble quantity, and higher aspect ratio. The predictability is affected by the inhomogeneous fluidization, but low pressure fluidization can generate similar bubble sizes with lower fluidizing mass compared to atmospheric pressure.
