A total 284 barcode sequences were obtained from 85 genera, 38 families 12 orders fishes. mean length 655 base pairs. average Kimura two parameter (K2P) distances within species,...
Resistive switching processes in HfO2 are studied by electron holography and situ energy-filtered imaging. The results show that oxygen vacancies gradually generated the oxide layer under ramped electrical bias, finally form several conductive channels connecting two electrodes. It also shows process occurs at top interface of hafnia layer. As a service to our authors readers, this journal provides supporting information supplied authors. Such materials peer reviewed may be re-organized for...
Electrochemical supercapacitors have drawn much attention because of their high power and reasonably energy densities. However, performances still do not reach the demand storage.
