Summary: In this study, Fe and Co/Fe modified H4Nb6O17 nanotubes were synthesized and evaluated as efficient materials for the removal of C2H5SH. The results showed that Co/Fe modified H4Nb6O17 nanotubes exhibited enhanced removal performance for C2H5SH. The introduction of Co additives promoted the reduction of Fe3+ and the formed Fe3O4 served as the main active species to promote the oxidation of adsorbed C2H5SH. The Co/Fe-HNT-0.3 nanotubes retained a high C2H5SH removal efficiency of 96.5% even after multiple regeneration cycles.

Summary: Single-metal high-temperature solid sorbents for syngas cleaning were synthesized and tested in a fixed-bed reactor, with Mn-based sorbent showing the best sulfur removal ability at temperatures above 600 degrees C. Sorbents with Fe, Cu, and Mo may lead to SO2 formation initially, but this can be avoided through pre-reduction treatment.

Summary: In this study, porous Mn-Fe composites with hollow nanocubes were used as catalysts for passive NOx adsorption. The effects of various factors on the adsorption capacity were investigated, and the developed Mn1Fe2-450 catalyst showed excellent NOx uptake at 200℃. The presence of Mn3+ and Fe2+ species and gaseous O-2 contributed to the NOx adsorption process. This work provides inspiration for the design of new adsorbent materials.

Summary: The ability of cellular concrete waste to remove hydrogen sulfide (H2S) from a mimic biogas was studied. Wetted conditions showed that 169 g of H2S could be removed per kg of material, and the H2S elimination capacity of cellular concrete waste could reach up to 32 g m-3 h-1. This technology could be a suitable and valuable technique for treating gas flowrates generated by decentralized do -mestic biogas digesters.

Summary: Carbon supraparticles with hierarchical porous structures are synthesized from lignin and cellulose nanofibrils. These carbon SPs exhibit high mechanical strength, large surface area, and excellent CO2 adsorption capabilities with low pressure drop, addressing limitations in mass transport and kinetics often found in nanoparticle-based systems. Additionally, the carbon SPs do not require heteroatom doping for effective CO2 uptake and can be easily regenerated for multiple adsorption/desorption cycles, making them cost-effective and highly efficient for gas sorption and capture.

Summary: This paper reviews the development of CO2 mineral carbonation technologies using industrial solid waste as feedstock and identifies energy and cost consumption concerns as limitations for scale-up applications. Further research on process parameter optimization and equipment design is needed to address these limitations and improve the feasibility for industrial applications. Recovery of high-value products during the carbonation process is highlighted as a potential solution to improve the economic viability of the process. Additionally, suggestions for future research directions include evaluating CO2 net emission reduction through life cycle assessment and developing new energy-saving approaches.

Summary: Metal/reducible metal oxide catalysts are widely used in hydrodeoxygenation reactions. However, the effect of the facet of metal oxide on the strong metal-support interaction (SMSI) and its consequence on catalytic performance are not well understood. In this study, Pt supported on anatase TiO2 with different dominant exposed facets were tested in the hydrodeoxygenation of m-cresol. The SMSI of Pt/TiO2 was strongly dependent on the facet of TiO2, with different facets showing different degrees of encapsulation. The facet with intermediate SMSI showed the highest reaction rate, turnover frequency, and lowest activation energy. This work provides insights into facet-dependent SMSI and its impact on catalytic activity.

Summary: In this study, we examined the role of tumor microenvironment and serum differential metabolites in the development of intrahepatic cholangiocarcinoma (ICC). The findings indicate that purine metabolites are increased in the serum of ICC patients. Additionally, the expression of purine metabolism-related genes, such as PPAT and IMPDH2, is correlated with ICC clinical features. Silencing PPAT in HCCC-9810 cells resulted in a decrease in malignant phenotype, while guanosine reversed this effect and promoted tumor growth.

Summary: In the presence of a Lewis base (L), [CpW(CO)(3)](2) undergoes metal-metal bond cleavage and then undergoes disproportionation to form [CpW(CO)(3)L](+) and [CpW(CO)(3)](-) when irradiated with blue light. We found that in the presence of pyridinium tetrafluoroborate, [CpW(CO)(3)](-) reacts further to form a metal hydride complex CpW(CO)(3)H. The reaction was monitored through in situ photo H-1 NMR spectroscopy experiments and the mechanism of light-driven hydride formation was investigated by determining quantum yields of formation.

Summary: A new regioselective route for surface modification of biological colloids using water as a medium is introduced, demonstrating site-specific reactions between cellulose nanofibers and acyl imidazoles. The method allows for obtaining CNFs with tailored surface interactions, without the need for drying or organic solvent exchange. This sustainable approach benefits from water presence and offers high chemical substitution selectivity, showing potential for application in reactive extrusion and compounding.
