Summary: Hydrate-based CO2 sequestration (HBCS) is a new method to store large amounts of CO2 in geological sediments as crystalline solids. This study investigates the characteristics and kinetics of CO2 hydrate formation and dissociation under different conditions. The results suggest that hydrate nucleation and growth are limited in a porous medium due to solid particles, limited CO2 mass transfer, and heat transfer. Limited CO2 diffusion, hydrate nucleation, and better protection of hydrates are key factors for successful formation in the porous medium.

Summary: In this study, methane separation from CMM gas mixture was achieved by forming sII and sH hydrates with the use of different thermodynamic promoters at moderate temperature and pressure conditions. The formation of sII hydrate showed better methane recovery, while the formation of sH hydrate demonstrated a better separation factor. The use of water-soluble hydrate promoter sodium dodecyl sulfate (SDS) enhanced the rate of hydrate formation for better separation efficiency.

Summary: The formation rates of methane hydrate are significantly affected by the grain size of the sediments, with lower rates observed in sand compared to powders. The final water conversion rate is similar in powders and can reach nearly 100% with sufficient gas supply, while the rate declines sharply at a certain water conversion point in all three types of porous media.

Summary: Sluggish formation kinetics is a challenge for the practical application of gas hydrate-based technologies. Carbon monoliths with controlled surface functional groups enhance the nucleating ability of methane hydrates. Carbonyl oxygen is identified as the most effective functional group in reducing induction time and enhancing formation kinetics. The turned hydrogen bonds near the CBCM surface contribute to the enhanced formation kinetics. Optimized carbonyl oxygen in CBCM significantly improves methane hydrate formation kinetics and storage capacity with outstanding cycle stability.

Summary: In recent years, interest in gas hydrates has grown due to their potential as an energy source and environmentally friendly alternative to storing and transporting natural gas. This study compared the effectiveness of sulfonated castor oil (SCO) and sodium dodecyl sulfate (SDS) as promoting reagents in the formation and decomposition of methane and methane-propane hydrates in a porous medium. The results showed that SCO significantly improved the water conversion rate in methane hydrates due to enhanced mass transfer in the presence of surfactants, while the effect on methane-propane hydrates was limited. Both SCO and SDS accelerated hydrate formation, but SCO required less supercooling. These findings suggest that SCO is comparable to SDS in promoting activity in porous media with varying water saturation.

Summary: The formation and dissociation behavior of CO2 hydrates in the presence of clay particles were investigated using low-field nuclear magnetic resonance. It was found that montmorillonite particles significantly promoted the conversion of water into hydrate, while illite particles had a weaker promoting effect. According to the DLVO theory, the total interaction potential between montmorillonite particles was much higher than that between illite particles.

Summary: Hydrophobic side chains in polymers play a significant role in antimicrobial activity and selectivity, with more hydrophobic polymers showing faster bacteria elimination but reduced selectivity at higher percentage content. Highly hydrophobic co-polymers with hexyl-functionalized cyclic carbonate kill bacteria via membrane-disruptive mechanism, with micelle formation leading to lower extent of membrane disruption. This study provides insights into the design of new antimicrobial polymers based on the effects of hydrophobic side chains.

Summary: The authors developed a hollow mesoporous Mn/Zr-co-doped CeO2 tandem nanozyme (PHMZCO-AT) with regulated multi-enzymatic activities to disrupt the H2O2 homeostasis, achieve intensive NCDT, and induce tumor apoptosis and death. The nanozyme catalyzes the conversion of superoxide anion into H2O2 in the tumor region and inhibits the off-target decomposition of H2O2. The elevated H2O2 is then converted into toxic hydroxyl radicals, leading to tumor cell death.

Summary: This work presents a molecular folding strategy to construct giant POSS molecules with inherent chirality. The folding of amino acid arms facilitated the chirality transfer from amino acids to ferrocene and POSS. The chiral orientation and chiroptical properties of POSS were found to depend on the substituents of alpha-amino acids. Through the kinetic nanoprecipitation protocol, chirality transfer from the molecular scale to the micrometer scale was achieved. This work opens up a new way to obtain discrete chiral molecular nanoparticles for potential chiroptical applications.
