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.

Ultrafast optical pulse generation enabled by carbon nanotubes is reported using a stretched-pulse fiber laser approach (shown in the graphic). This can lead to novel light sources meeting the pulse length, quality and energy requirements for many applications such as micro-machining and optical tomography, opening new opportunities in metrology, spectroscopy and biomedical diagnostics.

We present theoretical and experimental studies of Schottky diodes that use aligned arrays of single walled carbon nanotubes. A simple physical model, taking into account the basic physics of current rectification, can adequately describe both the single- tube and array devices.

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.
