Summary: We developed a simple and low-cost assay utilizing mesoporous silica nanoparticles for detecting analytes. Palladium nanoparticles covered with mesoporous silica (Pd@mSiO(2)) were used, and specific proteins or DNA were capped onto the nanoparticles to prevent catalyzation. When target antigens or complementary DNA sequences were present, the cap dissociated, allowing the conversion of non-fluorescent molecules to fluorescent molecules. The assay showed a wide detection range and has the potential for point of care diagnostics in low-resource settings.

Summary: Intensive and overuse of antibiotics have led to a rise in antibiotic resistance globally, creating a demand for alternative treatments. Metal ions like copper, silver, and zinc have been used to inhibit microorganism growth for centuries. This study focuses on the synthesis of metal and oxide nanoparticles immobilized on hollow mesoporous silica capsules (HMSCs) for efficient antimicrobial effects against both Gram-positive and Gram-negative bacteria. The results show promising potential for metal-loaded capsules as antibacterial delivery vehicles, providing sustained bacterial inhibition over several hours.

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 focuses on using a functional separator to suppress the shuttle effect of soluble lithium polysulfides in Li-S batteries. It is found that the functionalized sulfonic acid group not only accelerates the conduction of lithium ions, but also repels polysulfide anions through electrostatic interactions. The performance of the batteries is significantly improved with the use of this functionalized separator.

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: 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.
