Emerging technologies demand a new generation of lithium-ion batteries that are high in power density, fast-charging, safe to use, and have long cycle lives. This work reports charging rates and specific capacities of TiO(B)/N-doped graphene (TNG) composites. The TNG composites were prepared by the hydrothermal method in various reaction times (3, 6, 9, 12, and 24 h), while the N-doped graphene was synthesized using the modified Hummer's method followed by a heat-treatment process.

- The research focuses on optimizing a porous silica structure embedded with silver nanoparticles (Ag NPs) for improved separation in high-performance liquid chromatography (HPLC).
- The study achieved baseline separation of multiple polyaromatic hydrocarbons, with naphthalene demonstrating a high theoretical plate number of 36,000 m(-1).
- A significant finding is the effective separation of cis/trans-stilbenes, with a notable separation factor of 7 and a theoretical plate number of 76,000 m(-1), suggesting that geometric configuration affects retention behavior, challenging existing theories on Ag ion chromatography.
