Rapid characterisation of mixtures of hydrogen and natural gas by means of ultrasonic time-delay estimation [PDF]

Journal of Sensors and Sensor Systems
The implementation of the “power-to-gas” concept, where hydrogen and natural gas are blended and transported in the existing network, requires a quick, on-site method to monitor the content of hydrogen in the mixture. We evaluate a rapid characterisation

Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]

, 2010
Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...
