Polymer composite film for ultrafast photonics

Mon, 04/08/2019 - 12:41
Polymer composite films, particularly those based on polymers and layered nanomaterials, are attractive materials for exploiting the properties of multiple materials for applications in electronics and photonics. Recently, scientists have found that beta-lead oxide quantum dot /polystyrene composite films exhibit excellent stability in high humidity and strong saturable absorption response from visible to the near-infrared region. This makes them an attractive material for practical applications in optoelectronic devices in marine environments and other harsh condition, such as humid weather.

'Air chargeable' zinc-ion energy storage devices

Fri, 04/05/2019 - 15:57
Researchers propose a highly integrated system of an 'air charging' zinc-ion capacitor/battery. By scavenging energy from pervasive air, a zinc-ion capacitor/battery can be conveniently and easily charged without applying an additional power source. The system possesses a simply structure that consists of a flexible bifunctional U-shaped electrode (with the dual function of energy harvesting and storage), a zinc-metal electrode in middle, and two different polyelectrolytes (PAM and PANa) sandwiched between the metal zinc and the electrode.
