Summary: A high surface acidic ZrO2 nanoparticle was prepared with glucose as a reducing agent, and Pd nanoparticles were successfully embedded. The particle size and nature of acidic sites were found to have a significant impact on the conversion rate and selectivity. The activation energy and TOF of the catalyst were also calculated, and a linear relationship between Pd loading and selectivity was observed. Characterization of the spent catalysts showed that smaller nanoparticles were prone to agglomeration, resulting in decreased stability and activity. Therefore, high catalytic performance can be achieved by balancing Bronsted and Lewis acid sites, combined with the intrinsic activity of Pd species.

Summary: LC/TOF/MS was used to investigate the reaction between artemisinin (ART) and DNA bases, revealing that the reaction products increased significantly at 37 degrees C. The main driver of adduct formation was the change in temperature from room temperature to 37 degrees C. The addition of iron (II) ions to DNA base-ART mixtures resulted in new reaction products mediated by a different reaction mechanism.

Summary: In the past two decades, the understanding of multiple myeloma (MM) has significantly improved due to novel therapies targeting the MM in the bone marrow microenvironment. However, the mechanisms of resistance acquisition are still not well-known. The processes of autophagy and apoptosis play critical roles in MM cell growth, development, and survival. This review provides an overview of how autophagy and apoptosis are involved in MM progression and drug resistance, and suggests potential combination therapies targeting both pathways to improve outcomes in MM patients.

Summary: We report the catalytic hydroboration of esters and nitriles using a single titanium(IV) metal complex as a sustainable, economical, and efficient pre-catalyst. The complex showed excellent activity towards the hydroboration of a wide array of esters and nitriles with pinacolborane, giving high yields of alkoxyboranes and diboryl amines. In addition, the complex demonstrated greater tolerance to various functional groups. A plausible mechanism involving the formation of a titanium-hydride species as an active catalyst was proposed based on kinetics and NMR studies.

Summary: In this study, NiGa alloy particles supported on CeO2, ZrO2, and ZrO2-CeO2 solid solutions were prepared and characterized. The nature of the support was found to have a significant influence on the catalyst's activity and selectivity, with the crystalline structure of ZrO2 having the greatest impact. Pure ZrO2 showed the highest methanol selectivity and CO2 conversion at high Zr:Ce ratios. In equimolar and Ce-rich conditions, basic sites and oxygen vacancies were found to be the key parameters affecting methanol production.

Summary: Efficiently addressing the challenges of photocatalytic CO2 reduction to CH3OH is crucial. This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Summary: In this study, several silica-alumina catalysts modified with Ag were examined for the dehydration of 1,3-butanediol to 1,3-butadiene. Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
