  • Henri Bernard Beer registered his patent on mixed metal oxide electrodes in 1965. (wikipedia.org)
  • To improve the structural stability and energy density of sodium layered transition metal oxides (NaxTMO2, 0 ≤ x ≤ 1), substituting transition metals with different types of metals (e.g. (uwaterloo.ca)
  • Most rechargeable ion batteries employ transition metal oxides or phosphates as the positive electrode. (sdu.dk)
  • Oxides of nitrogen are found during manual metal arc welding and particularly during gas welding. (who.int)
  • OPVs typically consist of photoactive layers 20-100 nm thick sandwiched between both transparent oxide and metallic electrical contacts. (arizona.edu)
  • The magnetic nature of present electrode material with correlation of crystallite and morphological analysis revealed the signs of their excellence in energy storage behaviour. (edu.qa)
  • Thus, the prepared oxides are promising for supercapacitor applications. (researcher.life)
  • The design provides a means for electrodes to be modified ex situ and then incorporated directly into the flow cell. (figshare.com)
  • IrO 2 -coated titanium (IrO 2 /Ti electrode) was used as the substrate on which manganese oxide was coated (MnO x / IrO 2 /Ti electrode). (elsevierpure.com)
  • The microcoaxial electrode has been successfully applied to the real-time measurement of NO in endothelial cells, thereby demonstrating its effectiveness as an NO-specific electrode. (elsevierpure.com)
  • Developments in methods for characterisation of local atomic structures now allow us to gain detailed structural knowledge on the disordered part of the electrodes and studies within this field are emerging. (sdu.dk)
  • It was found that micro-structural grading could significantly enhance the gas transport but had negligible effects on the ohmic and activation overpotentials, especially for thick electrodes. (edu.hk)
