Highly hierarchical structures of silver indium tungsten oxide (AgIn(WO4)2) mesocrystals can be rationally fabricated via a microwave-assisted synthesis method by tuning the initial concentrations of the precursor. The morphology-, pressure-, and temperature-dependent photoluminescent properties of these materials have been investigated under hydrostatic pressures up to 16 GPa or at temperatures down to 10 K.

Wearable supercapacitors have been fabricated by conformally coating cotton fibers with carbon nanotubes, which function as both active material and current collector. Aqueous lithium sulfate, inexpensive and safe for human use, is used as the electrolyte. A surface treatment is necessary in order to improve the performance.
