Covalent organic frameworks are 2D or 3D porous crystals built by organic molecules through covalent bonds. Due to the framework stability and accurate control at molecular-level, this type of material shows potential applications in gas adsorption/separation, energy storage and conversion, drug delivery and so on. Recently, a collaborative work by SPST Assistant Professors Zhang Yuebiao and Ma Ya...

Organic-inorganic hybrid halide perovskites are emerging as a promising material in light-emitting diodes (LEDs) for their remarkable optoelectronic properties, including narrow full width half maximum (FWHM), high luminescence quantum yield (PLQY), and solution processability. The external quantum efficiency (EQE) of perovskites LEDs has exceeded 20% in just 5 years. However, the poor stability s...

Many natural biological systems—such as biofilms, shells and skeletal tissues—create multifunctional and environmentally responsive multiscale assemblies of living and non-living components. Such living materials grow, self-repair, and adapt to the environment, possessing many living attributes that are unattainable for most artificial materials. Taking inspiration from nature and leveraging the p...
