Summary: In this study, the promotion effects of four different morphologies and hydrophobic properties of graphite on hydrate were compared to identify a mode for promoting CO2 hydrate formation. The results showed that fluorinated graphene with superhydrophobic nanostructure had the strongest gas storage effect by promoting hydrate nucleation and sustainable growth. When combined with surfactant SDS, the system achieved the best performance with a gas storage capacity of 5.02 mmol/g H2O. This mode of enhancing mass transfer at the gas-liquid interface provided a novel way to promote hydrate-based applications and carbon sequestration technology.

Summary: This work presents a rheological analysis of cyclopentane hydrates formed in water-in-oil emulsions, investigating the influence of parameters such as pretreatment temperatures and cooling/heating rates. The study shows that the resulting hydrate slurry exhibits elasticity and shear thinning behavior, likely caused by breakdown of hydrate structures and alignment of hydrate agglomerates to the flow.

Summary: Although activated carbon can enhance hydrate nucleation kinetics, the promotion is significantly reduced under low driving force and large water contents. Immobilizing silver nanoparticles on activated carbon improves hydrate nucleation, shortening induction time by enhancing external nucleation. These findings provide insights for utilizing porous carbon materials in hydrate-based solidified natural gas technologies.

Summary: Antifreezes such as methanol and ammonia can enhance methane storage in binary clathrate hydrates like THF and TBAB. Methanol acts as a catalyst for methane hydrate formation and induces TBAB hydrates to form an orthorhombic structure suitable for methane storage. These findings suggest that methanol could play a crucial role in hydrate-based methane storage systems.

Summary: This study aims to investigate the formation characteristics of hydrate in a porous medium under different confining conditions, focusing on the effect of confining pressure on hydrate nucleation, growth, and saturation. The experimental results demonstrate the random nature of hydrate formation and the direct relationship between pressure decrease and hydrate saturation. Higher confining pressure conditions contribute to greater hydrate saturation within the porous medium.

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.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. 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.
