Summary: In this study, the co-gasification characteristics and synergistic interaction of municipal solid waste (MSW) and bituminous coal (BC) in CO2 atmosphere were investigated using thermogravimetric analysis. Results showed that addition of MSW can enhance the gasification reactivity of BC, leading to improved overall gasification efficiency. A significant synergistic effect was observed in the char gasification stage for all blends, with the optimal blend ratio of BC found to be 40% for the co-gasification process.

Summary: Photocatalysis has the potential to reduce CO2 greenhouse gases. Layered double hydroxides (LDHs) are promising photocatalysts with good catalytic activity, low synthesis cost, and large-scale preparation. This study focused on the effects of different divalent metal species on CO selectivity in aluminum-based LDHs and found that ZnAl-LDH exhibited better CO selectivity and CO yield compared to MgAl-LDH and NiAl-LDH. These findings provide a feasible strategy to improve the selectivity of CO photocatalytic reduction of CO2 by regulating divalent metal species in aluminum-based LDHs.

Summary: This work reports a self-adaptive electrode construction method to suppress dendrites growth on Li metal anode, which combines the advantages of electrolyte modulation and electrode structure design strategies. By preparing negatively charged titania nanosheets with densely packed nanopores, these holey nanosheets move spontaneously onto the anode under an electrical field, forming a mesoporous structure on the electrode surface. The resulting porous electrode has a large surface area with good lithiophilicity and can efficiently transfer lithium ions (Li+), promoting uniform deposition of Li metal. This work provides a new route for practical applications of Li-metal batteries.

Summary: Performance evaluation of drilling fluids is crucial for successful drilling projects. Rice husk ash (RHA) has been recognized as a promising alternative additive due to its renewable characteristics. The addition of RHA improves the rheological properties of drilling mud, but also increases filter loss and mud cake thickness. This study suggests that RHA can be a sustainable and cost-effective substitute to conventional chemical additives.
