Summary: Hierarchical zeolite ZSM-5 was synthesized using a template-free seed-assisted technique, and the influence of different synthesis conditions on its crystallinity and texture was studied. Characterization techniques including X-ray diffraction, scanning electron microscopy, and nitrogen adsorption measurements were employed. The catalytic activity of the synthesized samples in n-hexane cracking was evaluated and compared with that of commercial ZSM-5.

Summary: Hard template-directed growth methods are effective for synthesizing Ag nanostructures with precise size control, while soft template methods are flexible for synthesizing Ag nanostructures with various morphologies. However, the strong confinement effect of the hard template limits the diversity of Ag nanostructures and neglects the role of the soft template.

Summary: In this study, templates for over 100 zeolites were proposed using shape and binding metrics, and dual-OSDA approaches were rationalized. Selectivity maps based on phase competition metrics showed that small- and medium-pore zeolites exhibit stronger shape selectivity towards their templates compared to large-pore zeolites. Shape and volume descriptors were used to identify OSDAs that can act as synergistic pore-fillers for different cavities of zeolites. The application of this theory was demonstrated for the KFI zeolite, where tetraethylammonium and OSDAs repurposed from high-silica LTA synthesis were used as dual OSDAs. This work has the potential to contribute to the discovery of new synthesis routes for known zeolites using shape descriptors and repurposed OSDAs.

Summary: Encapsulation of enzymes into metal-organic frameworks (enzyme@MOF) can enhance enzyme stability. This study proposed a convenient seed-mediated strategy for efficient synthesis of enzyme@MOF from the perspective of MOF formation. The successful encapsulation of several proteins demonstrated the feasibility and advantages of this strategy, which provides an efficient, enzyme surface charge-independent, and non-modified method for the synthesis of enzyme@MOF biomaterials, warranting further exploration and application in diverse fields.

Summary: The pore structure significantly influences the performance of Ni-Mo/γ-Al2O3 catalyst and the desulfurization pathway of 4,6-dimethyldibenzothiophene. By adjusting the pore size, the reducibility of Mo species and the Ni-Mo-S structure can be modified, resulting in different reaction pathways and efficiencies. The design of deep desulfurization catalysts for environmental protection can be optimized based on these findings.

Summary: The study demonstrated that alkali treatment can enhance the catalytic activity and selectivity of isomers for n-dodecane hydroisomerization over Pt/ZSM-48 and Pt/ZSM-22 catalysts. The two catalysts have different effects on the generation of isomers, with Pt/ZSM-22 favoring the production of mono-branched isomers near the end of the chains, while Pt/ZSM-48 favoring the formation of di-branched isomers with methyl near the middle of the carbon chains.

Summary: The Ir/H-SSZ-13 catalysts showed higher activity and yields in methylcyclopentane ring-opening reaction compared to other catalysts. Ir species supported on H-SSZ-13-A exhibited higher activity than those on H-SSZ-13-B, especially at low Ir loading. The presence of strong acid sites on the external surface of H-SSZ-13-A promoted the reactivity of Ir/H-SSZ-13-A, making it a potential catalyst for ring-opening reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
