Summary: This article reviews bioinspired superhydrophobic fibrous materials from the perspective of fiber dimension scale. It summarizes the fiber dimension characteristics and mechanisms of several representative natural superhydrophobic fibrous systems, as well as artificial superhydrophobic fibers and their various applications. Nanometer-scale fibers achieve superhydrophobicity by minimizing the liquid-solid contact area, while micrometer-scale fibers enhance the mechanical stability of superhydrophobicity. In addition, surface modification strategies and conventional applications of superhydrophobic systems are presented.

Summary: High-performance p-type oxide thin film transistors (TFTs) have great potential for semiconductor applications, but often suffer from low hole mobility and high off-state currents. By applying a thin ALD Al2O3 passivation layer on the Cu2O channel and vacuum annealing, the TFT switching characteristics can be improved. Characterization by TEM-EDX and XPS shows that Al2O3 deposition on Cu2O reduces surface and forms a CuAlO2 interfacial layer. This, along with field-effect passivation, leads to improved TFT performance by reducing trap states and electron accumulation in the off-state.

Summary: Cellulose nanocrystals have the ability to form helical periodic structures, which generate structural colors preferentially reflecting left-handed circularly polarized light. By combining with a liquid crystal, the optical response can be modulated to achieve light reflection of both handedness with reversed spectral profiles. This study highlights the potential of hybrid cellulose systems to create advanced photoresponsive and polarization-tunable nanophotonics.

Summary: A profound understanding of the properties of unmodified and saturated fatty acid-modified calcite surfaces is essential for elucidating their resistance and stability in the presence of water droplets. Additional insights can be obtained by also studying the effects of carboxylic acid-saturated aqueous solutions. Our findings suggest that during droplet reverse dispensing and droplet evaporation, pinning of the three-phase contact line leads to the transport of dissolved fatty carboxylic acid and possibly calcium bicarbonate molecules to the contact line boundary.

Summary: Nuclear power is a clean energy source, but it produces hazardous fission products such as 90Sr. Researchers have developed submicron TiO2 and TiO2/SiO2 composite fibers to remove Sr2+ from water. These fibers showed excellent Sr2+ adsorption capacity, and the hydrothermally modified TiO2 fibers had the highest distribution coefficient. The nanorods on the fibers also remained undamaged in column operation tests, making them promising for industrial wastewater treatment.
