Summary: 2HN is a fluorescent dye commonly used in the development of Schiff base-hinged fluorophores for the recognition of cations, anions, and small molecules. One of the most unsafe and troublesome analytes is aluminum ion, causing high levels of contamination. Researchers have developed a strategy to construct Schiff base-derived fluorescent chemosensors to selectively bind aluminum ions, utilizing the commercially available 2HN molecule with polar groups for this purpose.

Summary: This study demonstrated the use of noble metal-free multi-component equiatomic oxides as efficient photo-catalysts for the degradation of Cr(VI) and methylene blue dye under natural sunlight, with complete reduction of Cr(VI) and significant degradation of methylene blue. The unique composition of these oxides, containing five components in equimolar amounts, played a key role in their effective photocatalytic activity. Additionally, the role of oxygen vacancies in the photo-catalytic reduction of Cr(VI) and degradation of methylene blue was discussed.

Summary: In situ modification of bacterial cellulose (BC) by adding agar and chitosan to the culture media leads to structural and morphological tuning, affecting water absorption/retention and rheological behavior. Agar-modified BC shows reduced pore volume and denser network with lower water absorption, while Chitosan-BC exhibits lower pore volume and reduced swellability with lower water retention. The viscoelastic deformation mechanism and water absorption behavior are discussed with respect to pore shape-size distribution and fiber dimension.

Summary: TiO2 nanoparticles decorated on silica nanoparticles exhibit significantly higher antibacterial activity even under low-power UV radiation. The best antibacterial activity is achieved with a molar ratio of SiO2:TiO2 = 2:1 (Si2Ti). At a concentration of 5 mg/mL, with only 1.66 mg/mL of active catalyst, Si2Ti sample achieved 100% killing of E. coli after 90 minutes of UV exposure. Si2Ti also showed good biocompatibility with more than 87% cell viability in fibroblast cells for 500 mu g/mL of the sample.

Summary: Improving the performance of chemiresistive gas sensors involves optimizing both the material and the electrode interfaces and interdigitated electrode structures (IDEs) geometry. In this study, the IDEs geometry (spacing between fingers, finger width, and number of fingers) was systematically optimized using a methane selective nanomaterial. The findings showed that changing the dimensions of the IDEs led to improved sensing response, with an increase of 1.2/1.54 times when adjusting the finger spacing/finger width, and a 2.42-fold improvement and a 3.91-fold decrease in sensing response when changing the number of fingers. This research opens up possibilities for fabricating low-power highly sensitive gas sensors that can be integrated into the Internet of Things.
