We report an electro- and photosensitive metal containing polymer material for alignment of liquid crystals (LCs). Irradiation with polarized light and/or application of dc-field result in an anisotropy of the polymer and formation of an easy orientation axes of a LC on the polymer surface. The light-induced anisotropy of the polymer and the LC anchoring on the polymer surface can be controlled by the low dc-field at room temperature.

CoFe and NiFe are used in the construction of Si-based metal-semiconductor-type photodiodes. Thin film layers are sputtered onto the-Si surface where Al metal contacts are deposited using the thermal evaporation technique. Film characteristics of the layers are investigated with respect to the crystalline structure and surface morphology.

Immobilizing catalysts and photosensitizers on an electrode surface is crucial in interfacial energy conversion. However, their combination for optimizing catalytic performance is an unpredictable challenge. Herein, we report that catalyst and photosensitizer monomers are selectively grafted one-by-one addition onto the electrode surface by interfacial electrosynthesis to achieve composition and sequence-controlled oligomer photoelectrocatalytic monolayers.

Large amounts of wastewater containing low-concentration (<10 ppm) rare-earth ions (REIs) are discharged annually in China's rare-earth mining and processing industry, resulting in severe environmental pollution and economic losses. Hence, achieving efficient selective recovery of low-concentration REIs from REIs-containing wastewater is essential for environmental protection and resource recovery. In this study, a pseudocapacitance system was designed for highly efficient capacitive selective recovery of REIs from wastewater using the titanium dioxide/P/C (TiO/P/C) composite electrode, which exhibited over 99% recovery efficiency for REIs, such as Eu, Dy, Tb, and Lu in mixed solution.
