A cheap battery
"...that can store renewable energy and last a decade. Renewable energies are still not competitive with traditional energy sources. With the discovery of a new flow battery for storing intermittent energy, researchers [...] have come a great deal further in closing the gap."
"...found in electrode for sodium-batteries prevents it from cracking. Although brittle, battery electrode material NaFePO4 can vastly swell and shrink when ions incorporate during charging and discharging."
"... Superconductive Atomically Thin 2D Material. Scientists from Manchester University show that phosphorene is superconductive when electrons are supplied by intercalated alkali metal atoms."
Safer, longer lasting batteries
"...for Smartphones from Lithium Metal. A research team at Rice University has overcome the problem of lithium metal building dendrites when used in batteries. They designed a novel electrode composed of a graphite-carbon nanotube hybrid with unprecedented lithium storage capacity."
Perovskite Material can harvest energy
"Wearable gadgets are most convenient and versatile when they can be powered without batteries. [Researchers] have found that the perovskite material KBNNO can harvest energy from sunlight, heat and movement."
Collective electrostatic effect
"... for next generation organic solar cells and quantum structures. Solar cells require the presence of two chemically different donor and acceptor materials to create an electric current from solar energy."
hyperlens arrays for super-resolution imaging
"Hyperlenses can overcome the diffraction limit but their fabrication is difficult and expensive. A new nanoimprint lithography method can produce hyperlens arrays in simple fashion and in large scale."
