This work demonstrates an electrically-tunable nematic liquid crystal (NLC) diffraction grating with a periodic electrode structure, and discusses the polarization properties of its diffraction. The efficiency of the first-order diffraction can be gradually controlled by applying external electric fields cross the NLC, and the maximum diffraction efficiency of the first-order diffraction that can be obtained is around 12.5% under the applied voltage of 5.0 V. In addition to the applied electric field, the efficiency of the first-order diffraction can also vary by changing the polarized state of the incident beam. Antisymmetric polarization states with symmetrical intensities in the diffractions corresponding to the +1 and -1 order diffraction signals are also demonstrated.

In this study, novel polyaniline-coated perovskite nanocomposites (PANI@CoTiO and PANI@NiTiO) were synthesized using an in situ oxidative polymerization method and evaluated for the photocatalytic degradation of Rhodamine B (RhB) a persistent organic pollutant. The nanocomposites displayed significantly enhanced photocatalytic efficiency compared to pure perovskites. The 1%wt PANI@NiTiO achieved an impressive 94% degradation of RhB under visible light after 180 min, while 1wt.

In this study, the dispersion behavior of MoS₂ in ionic liquids (ILs) with varying alkyl chain lengths was the primary focus of investigation, followed by the design of a novel PAM/SMA/CMC/PDA@MoS hydrogel. By optimizing the concentrations of CMC and PDA@MoS, a bifunctional hydrogel with both sensing and catalytic functions was successfully developed. Mechanical tests revealed that the PAM/SMA/CMC/0.

Trifluralin (FLL) is extensively used in rapeseed fields in the Qinghai-Tibet Plateau (QTP) region. However, the degradation kinetics of FLL in this area and its impact on environmental microbial communities are not yet known. To investigate the degradation patterns and ecological benefits of FLL, this study established a comprehensive method for detecting FLL residues and selected efficient degrading bacterial strains.

This study, we synthesized a graphene oxide@BiBTC MOF (GO@BiBTC) photocatalyst using a hydrothermal method. The resulting samples were comprehensively characterized using FT-IR, Raman spectra, XRD, SEM, TEM, XPS and UV-Vis spectroscopy. The photodegradation reaction fits the pseudo-first-order kinetics and the deterioration rate constants () value of BiBTC, GO@BiBTC MOF composites were 0.

The contamination of water with dyes stemming from the discharge of industrial waste poses significant environmental risks and health concerns. In this study, the phytoremediation potential of the wetland plant was investigated (as a function of plant biomass, pH, contact time, and initial dye concentration) for the removal of methylene blue and methyl red dyes from wastewater. The experimental adsorption capacities under the optimum conditions were found to be 1.
