Summary: This study compared the photocatalytic activities of active photocatalysts, including AgBr, ZnO, BiOI, and Cu2O, in the presence of a-MoO3. The results showed that a-MoO3 strongly inhibited the photocatalytic activity of TiO2, BiOI, Cu2O, and ZnO, but had no effect on AgBr. Therefore, a-MoO3 could be an effective inhibitor for evaluating newly explored photocatalysts.

Summary: A novel surface plasmon resonance (SPR) photocatalyst Au(T)-TiO2(MS) was fabricated by anchoring Au thorns on TiO2 hierarchical microspheres (MS). The Au thorns not only respond to visible and NIR light but also effectively promote the separation of photogenerated charge carriers in TiO2(MS). The photocatalyst displays excellent bactericidal activity and stability under red and NIR light irradiation.

Summary: This study explored the aromatic profiles of various seaweeds and seaweed extracts, identifying over 100 volatile compounds. Brown and red seaweeds were found to have distinct sensory properties, with individual seaweeds exhibiting different volatiles and odorants. This information may aid in the development of products incorporating dried seaweeds/extracts that are more appealing to consumers.

Summary: A TiO2-coated glass hollow fiber membrane was successfully synthesized and its photocatalytic removal of methylene blue from wastewater was investigated. The results showed that the membrane had good photocatalytic and antifouling properties, significantly improving the removal of methylene blue compared to the basement membrane. The membrane could be recycled multiple times with a high removal degree of methylene blue.

Summary: Metal-free photocatalysts in the form of covalent organic frameworks (COF-PRD) were utilized to activate PMS for the degradation of bisphenols under visible light irradiation. The degradation process was dominated by O-2(-), h(+), and O-1(2), and showed effectiveness in both aerobic and anaerobic conditions while reducing bioaccumulation effects and exhibiting excellent reusability.

Summary: This work developed TiO2-loaded lignin-derived carbon nanofibers (TiO2@LCNFs) using electrospinning, per-oxidation, and carbonization. The study systematically investigated the effects of TiO2 content, carbonization temperature, initial RhB concentration, and solution pH value on photocatalytic efficiency. Under optimized conditions, TiO2@LCNFs achieved up to 86% photocatalytic efficiency and excellent cycling stability for rhodamine B. The superior catalytic property of TiO2@LCNFs is attributed to the synergistic effect of uniform TiO2 distribution on fiber surface and good electrical conductivity of LCNFs.

Summary: The environmental conditions of wine regions determine the chemical composition and sensory characteristics of young Marselan wines. Using analytical methods such as gas chromatography-mass spectrometry and high-performance liquid chromatography, it was found that the concentrations of volatile compounds can differentiate young Marselan wines from different regions. The compounds and sensory attributes of Marselan wines are related to the specific environmental conditions of the wine-producing regions.

Summary: The biodegradation of thiocyanate by free and immobilized Bacillus brevis was studied. It was found that immobilized cells had a higher rate of thiocyanate degradation. Cells on lignite carbon matrix showed higher efficiency compared to cells on alginate beads. Immobilization increased the bacteria's tolerance to the toxic chemical. Immobilized Bacillus brevis on lignite carbon achieved degradation of 100 ppm thiocyanate in 20 hours. This technique is valuable for wastewater treatment due to its reduced cost and simplicity.

Summary: Quinoline-containing effluent from pharmaceuticals, dyes and pesticide industries pollutes the environment and affects human health due to its toxicity and nauseating odor. Biotreatment using isolated Bacillus subtilis immobilized on activated coconut shell carbon proves to be an effective method for degrading quinoline, even at high concentrations of 300 ppm, within a shorter time period compared to free cells. The stability and recyclability of immobilized cells make them suitable for the mineralization of heterocyclic organics in wastewater.
