Summary: In this study, spherical silica nanoparticles (SiO2 NPs) were prepared using a modified Stober's method and tested for the removal of methyl orange (MO). The SiO2 NPs had a zeta size of 152.5 nm, a PDI of 0.377, and a zeta potential of -5.59 mV. The adsorption of MO by SiO2 NPs was influenced by parameters such as initial dye concentration, reaction time, temperature, and pH. The highest adsorption rate was observed to be 69.40 mg/g of SiO2 NPs. The toxicity of the SiO2 NPs treated MO dye solution was tested and found to have no significant toxic effects on corn seeds and Artemia salina.

Summary: Conjugated porous polymers (CPPs) are a new family of functional porous materials with tuneable porosities and molecular architectures, showing great potentials in adsorption, light harvesting, and catalysis applications. This study describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs, resulting in CPPs with integrated properties of high surface area, hierarchical porous structures, and strong visible-light absorption. The obtained CPPs demonstrated relatively high adsorption capacity and high photocatalytic degradation efficiency towards organic dyes, with mechanism studies revealing the generation of singlet oxygen species as the main driving force for the dye degradation.

Summary: This study prepared flexible ultraviolet (UV) photodetectors (PDs) based on ZnO films on different flexible substrates using a simple dip-coating method. The PD on filter paper exhibited higher flexibility and stability compared to PDs on polyethylene terephthalate and A4 paper substrates. The PD on filter paper showed a significant switch response at a bending angle of 60 degrees. The excellent flexibility of the PD on filter paper was attributed to the loose and porous structure of the ZnO film.

Summary: Gallium Oxide (Ga2O3) shows great potential in photocatalysis due to its strong redox capability. However, its application is limited by working in the deep ultraviolet region and having a high recombination rate. By using reducing agents, the concentration of oxygen vacancy, and thus the band gap of Ga2O3, can be controlled, resulting in improved photocatalytic degradation efficiency.

Summary: Combining ZnO materials and other narrow bandgap materials is an effective way to create high-performance optoelectronic devices. In this study, a multifunctional optoelectronic device based on a CuO/ZnO p-n junction was fabricated. The device serves as a self-powered photodetector in a wide spectral range and also exhibits a photo-induced binary response. The device operates in the UV-vis-NIR region with a maximum responsivity of 1.24 mu A.W-1, specific detectivity of 9.77 x 10(6) Jones, and response/recovery time of around 20 ms under zero bias and 405 nm light irradiation (55 mW cm(-2)). The thickness of the CuO film greatly affects the performance of the photodetectors. The built-in field at the CuO-ZnO interface enables the device to operate without external power supply. The device also demonstrates a photo-induced binary response at a small forward bias, making it highly suitable for applications in light communication systems and optical chips.

Summary: This study investigates the photocatalytic degradation property of europium oxide (Eu2O3) nanoparticles synthesized via chemical precipitation and calcination processes, with surface modification using surfactants such as polyvinyl pyrrolidone (PVP) and hexadecyl trimethyl ammonium bromide (CTAB). The results show that Eu2O3 nanoparticles synthesized with surfactant CTAB exhibit improved photocatalytic degradation efficiencies for degrading rhodamine B dye compared to pure Eu2O3 nanoparticles and those synthesized with PVP. The enhanced performance can be attributed to the increased bandgap of Eu2O3 and the influence of the surfactant on the luminescence of Eu3+ and carrier redistribution of energy levels.

This study investigates the impact of different weak intermolecular interactions on the degree of charge transfer (DCT) using four four-ring-fused donors without heteroatoms. The results demonstrate that the DCT is dominated by charge transfer and pi-pi interactions, suggesting the importance of considering donor selection in understanding the contribution of various intermolecular interactions to the DCT.

Summary: In this study, two devices with different structures were constructed to investigate the effects of NiO growth above and below the TiO2 array on device performance. It was found that the device where NiO was grown below the TiO2 array showed better performance, with lower dark current, a large on-off ratio, and high detection sensitivity. The dense and uniform NiO film deposited on the FTO substrate plays a key role in enhancing the performance of the D-NT photodetector.
