exhibits record-high volumetric and gravimetric acetylene (CH) uptakes of 210 cm (STP) g and 227 cm (STP) cm at 295 K and 1 atm, respectively. Grand canonical Monte Carlo (GCMC) simulation indicates that those remarkable CH uptakes are attributed to the open Cu sites and tailored cages.

Biomass has attracted considerable interest in the field of energy storage because of its outstanding characteristics, such as superior charge transport ability, affordability, eco-friendly, structural versatility, and renewability. Moreover, biomass-derived activated carbons, combined with pseudocapacitive materials, have recently gained popularity as efficient electrochemical components for energy storage devices. In this study, activated carbon was prepared from pinecone flowers as the biomass precursor through a process involving alkaline treatment and pyrolytic carbonization in an inert gas environment.

Lithium-sulfur batteries (LSBs) are an emerging energy storage system with high volumetric and gravimetric energy densities. However, a significant challenge is the shuttle effect caused by intermediate polysulfide species. The polysulfide species aids in reducing active material retention and degrading battery performance.

Multiwalled carbon nanotube (MWCNT) Li-O cathodes can achieve high gravimetric capacity. However, the macropores of these cathodes require a relatively large mass of electrolyte to fill, resulting in lower true gravimetric and volumetric capacities. Here we report a simple method to incorporate a mesoporous material, carbon nanochains (CNCs), into the macropores of MWCNTs, resulting in composite cathodes that fully utilize their pore structure to store LiO product.

The development of advanced hydrogen storage materials is essential for the adoption of hydrogen-powered vehicles as a sustainable alternative to fossil fuels. Metal-organic frameworks (MOFs) have emerged as promising candidates for meeting the Department Of Energy (DOE) storage targets. This study employs grand canonical Monte Carlo simulations to evaluate the usable gravimetric and volumetric storage capacities of hydrogen in newly synthesized Zn- or Cd-based MRT (Moldova Research Team) MOFs.
