#Orderly arranged bead-chain ternary nanocomposites for supercapacitors

“#Orderly arranged bead-chain ternary nanocomposites for supercapacitors” A schematic diagram of Cu2O-Mn3O4-NiO ternary nanocomposites preparation process. Compared with the traditional hydrothermal method, the materials prepared by electrospinning are nanostructure, which improved the electron transport capacity and the energy storage capacity of metal oxide. The acquired Cu2O-Mn3O4-NiO ternary nanocomposites were arranged in orderly metallic nanostructures, which…

#Chemical thermometers take temperature to the nanometric scale

“#Chemical thermometers take temperature to the nanometric scale” Temperature map of a gold nanowire on a silicon substrate, Joule-heated by the application of an electrical current of 7 mA, obtained through infrared thermography (top) and a spin-crossover surface thermometer (bottom). While heating remains undetectable in infrared due to low thermal and spatial resolution, temperature distribution…

#Replacing lithium with sodium in batteries

“#Replacing lithium with sodium in batteries” Credit: Pixabay/CC0 Public Domain An international team of scientists from NUST MISIS, Russian Academy of Science and the Helmholtz-Zentrum Dresden-Rossendorf has found that instead of lithium (Li), sodium (Na) “stacked” in a special way can be used for battery production. Sodium batteries would be significantly cheaper and equivalently or…
