Summary: The use of zeolite-containing Co catalysts in liquid hydrocarbon transformations during Fischer-Tropsch synthesis demonstrated a decrease in the average molecular weight of the products without increasing methane selectivity. The introduction of zeolites cleared the catalyst pore system of heavier hydrocarbons, suggesting a potential role in controlling product composition over hybrid catalysts.

Summary: The CO2-to-aromatics process converts carbon dioxide (CO2) into valuable petrochemicals, specifically aromatics like benzene, toluene, and xylene, using metal/zeolite bifunctional catalytic systems. These aromatics are currently derived exclusively from fossil fuels and are used in various industrial applications. This process can help mitigate climate change by reducing greenhouse gas emissions and promoting a more sustainable and circular economy by reducing reliance on fossil fuels.

Summary: Metal nanoparticles on porous supports have wide applications in various scientific areas. This study demonstrates that bismuth promoter can enhance the stability of cobalt catalysts, leading to migration and redisersion of bismuth over the surface of cobalt nanoparticles during the reduction step. The preferential localization of mobile bismuth promoter at the steps and edges of cobalt nanoparticles hinders cobalt sintering and carbon deposition, resulting in improved catalyst stability.

Summary: In this study, Fe3O4 bulk catalysts assembled from nanoparticles were synthesized to investigate the size effect of Fe phase. The results show that when the particle size is smaller than 10 nm, the catalysts exhibit similar catalytic activity, while beyond 10 nm, the activity decreases significantly. Particularly, Fe3O4 with a nanoparticle size of 9.9 nm shows the highest activity, selectivity and ratio. Smaller particles contribute to C5+ formation while inhibiting CH4 selectivity.

Summary: A novel series of CHOR-HEPT non-nucleoside HIV-1 reverse transcriptase inhibitors were developed based on structure-based design strategy, using compound 6 as the starting point. These compounds showed moderate to good activity against wild-type HIV-1 strain, with EC50 values ranging from 0.18 to 51.88 mu mol/L and SI values ranging from 4 to 907. Compound 14aj with a CHOH linker and compound 13i with a CHOTMS linker exhibited improved anti-HIV-1 activity (EC50 = 0.18 mu mol/L and 0.20 mu mol/L) and higher selectivity (SI = 907 and 665) compared to the lead compound 6 (EC50 = 0.59 mu mol/L, SI = 9).

Summary: This study discovered that iron oxide nanoparticles (IONPs) can significantly enhance the production of type-I interferon (IFN-I) and achieve a dosage-sparing effect when combined with the STING agonist MSA-2. Acid-ionizable copolymers are coassembled with IONPs and MSA-2 to concentrate STING activation in lymph nodes and improve antigen cross-presentation. The iron nanoadjuvant PEIM effectively delivers antigens to antigen-presenting cells (APCs) and induces a potent and durable antitumor immune response.

Summary: Porous graphitized carbon fibers (PGCFs) with enhanced hydrophobicity were prepared by catalytic graphitization of ACFs. They showed high adsorption capacity for toluene, cyclohexane, and ethanol, and even increased adsorption of ethanol under humid conditions. The 7C electrons and high polarizability of PGCFs strengthened their interaction with non-polar organics, and capillary condensed water in mesopores acted as absorbate for polar ethanol.

Summary: This study determined the photocatalytic degradation behavior of aromatic micro-pollutants (AMPs) and developed a quantitative structure-activity relationship (QSAR) model for predicting the photooxidation reaction of AMPs. The model revealed that the single electron transfer pathway and adsorption were the significant steps in the reaction process, and electron-donating substituents promoted the photooxidation of AMPs. This research provides guidance for studying the mechanism and selective oxidation of AOPs photooxidation system based on graphene oxide (GO).

Summary: Bi2WO6 with double active sites of tunable metallic Bi and oxygen vacancies (OV-Bi/Bi2WO6) was prepared by solvothermal treatment and used as an efficient photocatalyst for the partial oxidation of cyclohexane (CHA) to cyclohexanone (CHA-one) in air. The Bi : Bi2WO6 ratio in OV-Bi/Bi2WO6 could be tailored by controlling the solvothermal temperature, and the synergistic effect between DMF and EG increased the reduction of MDF/EG and promoted the production of Bi. OV-Bi/Bi2WO6 showed significantly enhanced photocatalytic activity attributed to its specific surface area, photo-absorption, oxygen vacancies, and efficient electron-hole separation.

Summary: In this study, 55 bZIP transcription factors were identified in Pinus massoniana and a systematic analysis was performed. The bZIP TFs of P. massoniana were divided into 11 groups based on phylogenetic analysis. Each bZIP protein contained a conserved bZIP domain and exhibited similar motif types and numbers within the same group. Transcriptional profiles revealed that 25 PmbZIP genes responded to pine wood nematodes at different levels. Among them, PmbZIP3, PmbZIP4, PmbZIP8, PmbZIP20, and PmbZIP23 were upregulated during the nematode inoculation process.

Summary: This study investigates the influence of microscale structure of MWW zeolites on the kinetics for acylation of anisole with acetic anhydride. It is found that the acylation reaction occurs solely on the external acid sites of MWW zeolites, and the single-layer MWW (SL-MWW) exhibits higher recycle stability compared to the multiple-layer MWW (ML-MWW). The confinement effect within 12MR pockets on the surface of SL-MWW results in difficult desorption of product and small rate constant.

Summary: Designing a highly active single atom catalyst, particularly noble-metal atoms in two-dimensional LDH nanostructures, is essential for speeding up the slow oxygen evolution reaction (OER). By reducing a solution, Ru single atoms (SAs) are fixed on NiFe LDH to form SARu/NiFe LDH. The activity evaluation shows that SARu/NiFe LDH exhibits higher activity and Faradaic efficiency compared to pure NiFe LDH.

Summary: In this study, a Se,P,N-tridoped carbon nanomaterial (Se,P,N/CN-900) was successfully prepared and used as a metal-free catalyst for the direct ammoxidation of alcohols to nitriles with aqueous ammonia and molecular oxygen. The tridoped carbon catalyst exhibited highly efficient catalytic performance and good stability, enabling the conversion of various (hetero)aromatic alcohols to corresponding nitriles with high yields. To the best of our knowledge, this is the first work to achieve ammoxidation of alcohols to nitriles with a high efficiency over multidoped carbon materials.
