Polystyrene-MOF-Derived 3D Hierarchical Porous Carbon for High-Performance Supercapacitors.

The ability to tailor surface area, porosity, and morphologies has driven extensive research into the synthesis of metal-organic frameworks derived carbons and their applications in energy storage. This study presents the development of three-dimensional hierarchically porous carbon derived from polystyrene and small-sized zeolitic imidazolate framework-8 (ZIF-8) particles. Incorporating nanometer-sized ZIF-8 particles forms a core-shell structure in the pre-carbonization stage, transforming into a porous carbon material with a range of pores from micro to macropores after carbonization.

A Prospective Study on Fixation of Syndesmotic Ankle Injury: Tight Rope Versus Screw Fixation.

Background Syndesmotic injury can result in significant instability and long-term complications if not treated correctly. Traditional management has involved transyndesmotic screw fixation, but a newer technique, the tight rope system, has been developed to mitigate some of the issues related to screw fixation, such as hardware discomfort and the necessity for hardware removal. Methods In this randomized, prospective study, 32 patients with ankle injuries requiring syndesmotic fixation were equally divided into two groups: one receiving the tight rope system (n=16) and the other undergoing screw fixation (n=16).
