Summary: In this study, supported catalysts V2O5/3D g-C3N4 were prepared using a solvothermal method and programmed calcination, with a vanadium-based ionic liquid (V-IL) [(C8H17)3NCH3]3H3V10O28 as the vanadium source and 3D porous carbon nitride (3D g-C3N4) as the carrier. The use of V-IL promoted the high dispersion of V2O5 on the carrier and effectively avoided agglomeration. As a result, the catalytic oxidative desulfurization activity of V2O5/3D g-C3N4 was greatly enhanced, reducing the content of dibenzothiophene in model oil to 1.2 ppm under appropriate conditions. The recycling capacity and the possible process of oxidative desulfurization were also discussed.

Summary: The high costs of commercially available desulfurization technologies in the refinery industry call for the development of novel, efficient, and sustainable alternative processes. Nitrogen compounds also negatively affect the process efficiency. Thus, effective alternative methods capable of simultaneously removing sulfur and nitrogen from fuels under economic and sustainable procedures are desired in the petroleum industry. This study presents a sustainable catalytic process that combines oxidation and liquid-liquid extraction to efficiently remove sulfur and nitrogen from fuels. The catalyst used was a MIL-100(Fe)-based composite containing phosphomolybdic acid (PMo12) as the active center, which achieved complete desulfurization of a model fuel containing refractory sulfur and nitrogen compounds in just 30 minutes.

Summary: One disadvantage of using inorganic solid catalysts is the production of solid waste. This study developed a fully organic supported ionic liquid catalyst for desulfurization. The catalyst showed excellent dibenzothiophene removal efficiency and remained effective even after six regeneration cycles.

Summary: This article reports a novel porous phosphomolybdate-based poly(ionic liquid) catalyst with 70% water (PDIM-PMo-W70%). The catalyst showed a turnover frequency (TOF) value of 41.15 h-1 for dibenzothiophene (DBT) removal, which was 35.47 and 9.92 times higher than that of HPMo and PDIM-PMo, respectively. The effects of water content, reaction temperature, H2O2/S molar ratio, catalyst dosage, and different sulfur-containing compounds on the oxidative desulfurization (ODS) performance were investigated in detail.

Summary: In this study, a renewable Pickering emulsion system was demonstrated to overcome the mass transfer resistance at the liquid-liquid interface and facilitate catalyst recycling. The design of bifunctional materials, including Janus graphene oxide (GO) 2D-sheets, amino-modified SBA-15 (NH2-SBA-15) mesoporous microspheres, and H3PW12O40 (HPW), allowed for the enlargement of the interfacial contact area and easy recovery of the catalyst. The unique properties of the catalyst, such as large specific surface area, exposed catalytic active sites, and high pore volume, also contributed to the rapid diffusion of reactants and products.

Summary: The study used a heparin-mimicking polymer with a negatively charged surface to create an in vitro cell culture platform that replicated muscle atrophy-like phenotypes. By inhibiting myoblast fusion into myotubes, the heparin-mimicking moieties affected the expression of myogenic factors, myotube fusion-related markers, and focal adhesion kinase. Transcriptome analyses revealed that these moieties significantly downregulated the insulin/PI3K/mTOR and Wnt signaling pathways by inhibiting FAK/Cav3.

Summary: An ultra-selective and reproductive ratiometric platform was developed for miRNA-18a detection using the ratio of Ru(phen)32+ electrochemiluminescence (ECL) signal and methylene blue (MB) electrochemistry (EC) signal, amplified by toehold-mediated strand displacement (TMSD). Stable DNA nano-clews (NCs) loaded with MB were synthesized through rolling circle amplification reaction. A Ti3C2-based nanocomposite served as a carrier for both Ru(phen)32+ and gold nanoparticles to provide a constant ECL internal reference. The biosensor exhibited high selectivity and accuracy, with a limit of detection of 9 aM and satisfactory results in serum sample detection.

Summary: Hydrogels have become popular in tissue engineering and regenerative medicine for their biocompatibility, tunable degradation, and low immunogenicity. Silk fibroin (SF) is a commonly used biopolymer due to its known biocompatibility and range of mechanical properties. However, its simple structure limits its usability. One emerging strategy is the chemical functionalization of SF, allowing for versatile processing and making SF a useful bioink for 3D printing.
