The marriage of metal ions and black phosphorus - a new generation of semiconductor transport materials

NanoWerk.com - Wed, 03/07/2018 - 07:35
Due to its fascinating properties, black phosphorus (BP) has demonstrated appealing potential for not only building (opto)electronic devices, but also in many other areas such as lithium-ion batteries, solar cells, sensors, thermoelectric devices, supercapacitors, and phototherapy. Researchers now have demonstrated that modifying BP with metal ions solved its previous instability problem, which hindered the practical application of BP in electronics and optoelectronics; while at the same time further enhancing the original superior transport properties.

Reshaping energy landscape of phonons in nanocrystals

ScienceDaily.com: Nanotechnology News - Wed, 03/07/2018 - 00:37
Phonons, which are packets of vibrational waves that propagate in solids, play a key role in condensed matter and are involved in various physical properties of materials. In nanotechnology, for example, they affect light emission and charge transport of nanodevices. As the main source of energy dissipation in solid-state systems, phonons are the ultimate bottleneck that limits the operation of functional nanomaterials.

Contact lenses with built-in biofuel cells as power supply

NanoWerk.com - Tue, 03/06/2018 - 09:23
Enzymatic biofuel cells (EBFCs) are bioelectronic devices that utilize enzymes as the electrocatalysts to catalyze the oxidation of fuel and/or the reduction of oxygen or peroxide for energy conversion to electricity. EBFCs have already been demonstrated as wearable epidermal tattoo biosensors and in new work, researchers report the fabrication flexible EBFCs with flexible nanoporous gold electrodes that were modified with lactate oxidase and bilirubin oxidase for use as a lactate/O2 biofuel cell.
