Summary: Mesoporous silica nanoparticles (MSN) are potential drug carriers with high drug loading capacity and degradability under biologically relevant conditions. Dissolution studies of MCM-48 MSN in the presence of proteins show that protein concentration affects the kinetics of dissolution and leads to the formation of core-shell structured particles. The results suggest that MSN dissolution kinetics is faster under typical in vitro conditions compared to full serum conditions.

Summary: Formaldehyde emitted from household products is harmful to human health. This study compares the formaldehyde adsorption characteristics of mesoporous and mesoporous hollow silicas synthesized with or without a calcination process. The mesoporous hollow silica synthesized without a calcination process has the best adsorption performance, followed by the mesoporous hollow silica synthesized with a calcination process and mesoporous silica. This research demonstrates the potential of mesoporous hollow silica as an effective support for harmful gas adsorption.

Summary: Tumbling chemical vapor deposition (T-CVD) method for gas phase grafting (GPG) on mesoporous silica offers sustainable, cost-effective, and time-efficient approach. Gas phase methodology results in higher propylamine contents, higher surface density, and better CO2 uptake compared to traditional solution grafting. Additionally, GPG is suitable for grafting granules and pellets with limited mechanical strength, providing higher efficiency and less waste.

Summary: The adsorption of polymers on the surface of mesoporous silica nanoparticles allows for versatile adhesion between hydrogels or biological tissues. However, when the number of nanoparticles deposited exceeds a critical threshold, thick multilayers form at the interface and decrease the adhesion strength. To overcome this limitation, spherical aggregates were prepared by spray drying, resulting in stronger cohesion between nanoparticles. The adhesion energy with these supraballs was significantly enhanced compared to nanoparticles, and corrugated interfaces stabilized by supraballs contributed to the largest adhesion enhancement.

Summary: Rapid development in technology, industry, and agriculture has led to the release of a large amount of pollutants, including metal ions, into the environment. Due to their toxicity and persistence, heavy metals have become a major concern, causing adverse effects on the environment and population. Municipal and industrial effluents need to be treated thoroughly before being discharged or used for irrigation. This review focuses on mesoporous materials and discusses their synthesis and application in wastewater treatment, highlighting the mechanisms of metal adsorption and presenting examples of their multiple uses for metal removal. The information in this review can be utilized by researchers and environmental engineers involved in the development of new adsorbents and improvement of wastewater treatment technologies.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

Summary: This study presents a new method for preparing a microporous Ni2P/C catalyst with high catalytic activity. The redox reaction and carbon matrix formation during high-temperature treatment contribute to the stability and activity of the catalyst. Experimental and analytical results suggest that the microporous structure of the composite plays a crucial role in its catalytic performance. These findings are important for practical applications of efficient hydrogen production by water electrolysis.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
