Summary: The study found that nitrogen doped hydrochars (NDHCs) synthesized from shrimp waste using one-pot hydrothermal carbonization have large surface areas and porous surfaces. When used as photocatalysts, the removal efficiency of methylene blue (MB) by NDHCs was significantly higher than that of glucose-derived hydrochar (GHC), attributed to enhanced adsorption by porous surfaces and nitrogen-based functional groups.

Summary: By coupling a hybrid material with a biofilm, the removal efficiency of TC under visible light can be significantly enhanced, with EPS promoting the production of hydroxyl radicals. The biofilm in the coupled system tolerates TC stress by regulating gene expression and enzyme activity, ensuring stable and efficient TC removal. This approach offers a promising method for removing refractory organics like TC from water and provides insight into the mechanisms involved in TC removal by microbial aggregates combined with new functional materials.

Summary: This paper describes two new visible-light-promoted radical reactions of alpha-azido amides. N-aryl alpha-azido tertiary amides were transformed into aminyl radicals through reduction of the azido group, followed by N-to-N aryl migration to form alpha-anilinyl-functionalized amides; on the other hand, alpha-azido secondary amides reacted with ethanol and i-Pr2NEt to yield imidazolinone products.

Summary: In the field of photocatalysis, loaded photocatalyst offers advantages of controlled morphology, uniform preparation, low cost, and easy recovery, making it a potential substitute for powder photocatalysts. In this study, TiO2 and Cu7S4 hybrid materials with oxygen vacancies grown on copper mesh were prepared. The enhanced photocatalytic performance of the material can be attributed to the synergistic effect between the interfacial electric field of the heterostructure and the abundant oxygen vacancies. This research provides insights into the design of S-scheme photocatalysts for efficient nitrogen reduction.

Summary: A new approach for the synthesis of alpha-aminosilanes using photoredox catalysis was presented, providing highly functionalized products in good yields under mild conditions. Both primary and secondary amines can be used for this transformation, and optically pure alpha-aminosilanes can be obtained by using chiral amines. Mechanistic studies indicate that the reactions proceed through radical/radical cross-coupling of silyl radicals with alpha-amino alkyl radicals.

Summary: This study presents a visible-light-promoted strategy for the selective anti-Markovnikov hydrooxygenation of unactivated alkenes. A carefully designed reagent releases a highly reactive and strongly underdeveloped alkoxycarbonyloxyl radical upon reduction, which selectively adds into the alkenes. This methodology expands the toolbox for regioselective hydrofunctionalization and could serve as a complementary strategy to the established hydroboration/oxidation protocol.

Summary: In this study, ZnO/carbon spheres composites were prepared using zinc chloride and potassium oxalate as activating agents. The effects of their addition and preparation conditions on carbon dioxide adsorption properties were investigated. It was found that the sorption capacity measured at 40 degrees C confirmed the trend measured at 0 and 25 degrees C. The sample activated using potassium oxalate and modified using zinc chloride exhibited stable performance and high CO2 adsorption capacity during the consecutive multicycle adsorption-desorption process.

Summary: This study presents the visible-light photocatalytic performance of 3-aminopropyltriethoxysilane (APTES)-modified TiO2 nanomaterials obtained by solvothermal modification and calcination. The APTES/TiO2 photocatalysts exhibit higher pore volume and specific surface area, and the adsorption process negatively affects the photocatalytic properties. The highest dye decomposition degree is observed for nanomaterials calcined at 900 degrees C with optimal APTES concentration of 500 mM.

Summary: Nanocomposites based on nanocrystalline titania modified with graphene-related materials showed the presence of magnetic agglomerates. The magnetic resonance spectra parameters depended strongly on the materials' modification processes. Reduction of graphene oxide increased the number of magnetic moments and caused changes in reorientation and relaxation processes. At room temperature, wide resonance lines dominated in all studied nanocomposites, with narrow resonance lines derived from conduction electrons in some cases. Some nanocomposites exhibited single domain magnetic (ferromagnetic) arrangement, while others showed magnetic anisotropy. In addition, EPR spectra of free radicals were observed for all samples at 4K. Magnetic resonance imaging methods can capture even small number of localized magnetic moments, significantly affecting the physicochemical properties of the materials.

Summary: This paper describes a new approach for hydrogen production from water using carbon dioxide-mediated water decomposition under UV radiation. By saturating the water solution with dissolved sodium hydroxide and gaseous carbon dioxide, the formed bicarbonate and carbonate ions prevent the recombination of hydroxyl and hydrogen radicals, leading to the prioritized formation of hydrogen gas. In the best system, the hydrogen production reached 0.6 μmol/h during 24 hours of UV-C radiation.

Summary: This paper investigates the effects of fumed silica modification and calcination temperature on the physicochemical properties and activity of photocatalysts under UV-VIS and VIS light. The materials were synthesized using titanium tetraisopropoxide hydrolysis and subsequent calcination. Various analytical techniques were used to characterize the nanomaterials. It was found that SiO2 modification inhibited phase transformation and crystal growth during calcination. The photocatalytic activity was enhanced by SiO2 addition and calcination, with the highest activity observed for the SiO2(11.1%)/TiO2_600 photocatalyst.

Summary: Industrial TiO2 suspension from sulphate technology was used for samples preparation. One sample was directly calcined in an argon stream at 800 C-o. The second one, before the calcination in the same conditions, was modified with APTES in such a way that the final product contained about 2 wt% of silicon. Photocatalysts were tested in the CO2 reduction reaction containing the addition of gaseous nitrogen and water vapour. No activity was observed in the CO2 reduction reaction for a directly calcined sample that mainly consists of a rutile phase. It was found that the addition of silicon prevents the anatase-to-rutile phase transition by forming a Si-O-Ti chain containing the anatase phase and leads to gaseous products: hydrogen, carbon monoxide and methane, and ammonia. The presence of silicon generates paramagnetic recentres with g= 2.0028, which are associated with oxygen vacancies and delocalized electrons. This electronic structure is critical to the photocatalytic reduction of CO2 because the pure rutile phase (without silicon modification) does not reduce CO2, but only the presence of ammonia was found in the products.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
