Black phosphorus sponges comprising ultrathin, large and unoxidized nanosheets are prepared and used for an all-solid-state supercapacitor.

A self-regulated dynamic nanohybrid that can sensitively respond to hyperglycemic microenvironment is developed. The nanohybrid with a core/shell structure is produced through a single-step microfluidics nanoprecipitation method, where drugs-loaded porous silicon (PSi) nanoparticles are encapsulated by H₂O₂ responsive polymeric matrix.

Antifreeze-protein mimic polymers are shown to enable solvent-free storage of important proteins for therapy and biotechnology by modulating ice growth.

Focused ion beam milling of self-assembled magnetic superstructures is demonstrated as a novel approach to fabricate porous materials with tunable porosity. During exposure to the ion beam, nanoparticles in the superstructure are subjected to combined milling and melting, thus merging together into a porous network.

Controlled reduction of GO thin-films at room temperature with spatial resolution simply by application of a voltage, without the intentional use of electrolytes, has been demonstrated.

The majority of gels exhibit nanoscale spatial variations in crosslink density. We present the first 3D super-resolution microscopy images of dye tagged cross-link distributions in microgels and hydrogels. The morphology of nanoscale features never imaged previously in microgels, are revealed.
