FeO hard templating to assemble highly wrinkled graphene sheets into hierarchical porous film for compact capacitive energy storage.

Highly wrinkled graphene film (HWGF) with high packing density was synthesized by combining an electrostatically self-assembling process, a vacuum filtration-induced film assembling process and capillary compression. FeO nanoparticles were used as a low-cost and environment-friendly hard template. Hierarchical porosity and high packing density were achieved with the aid of capillary compression in the presence of FeO nanoparticles.

A highly selective long-wavelength fluorescent probe for hydrazine and its application in living cell imaging.

A highly selective long-wavelength turn-on fluorescent probe has been developed for the detection of NH. The probe was prepared by conjugation the tricyanofuran-based D-π-A system with a recognizing moiety of acetyl group. In the presence of NH, the probe can be effectively hydrazinolysized and produce a turn-on fluorescent emission at 610nm as well as a large red-shift in the absorption spectrum corresponding to a color change from yellow to blue.
