Researchers have developed a microsupercapacitor that exploits three-dimensional porous electrodes. These micropower units are expected to enable a new generation of 'smart' products, such as self-powered sensors for wearables, security, structural health monitoring and internet-of-things applications.
The addition of a few nanometers of a thin layer of aluminum oxide protects a perovskite solar cell against humidity - still a major stumbling block to the commercial application of this new type of solar cell.
In nanotechnology control is key. Control over the arrangements and distances between nanoparticles can allow tailored interaction strengths so that properties can be harnessed in devices such as plasmonic sensors. Now researchers use dendrimers that mimic the electron valency of atoms and link them into arrays using molecules that coordinate with the dendrimer as they would form a covalent electron pair in their valence shell - 'electron pair mimicry'.
