Micro-channel device, protected alloy surface in catalyst, alumina supported catalyst, catalyst intermediate, and method for forming catalyst and micro-channel device.
Surface impedance of metals in infrared region is calculated for an arbitrary Fermi surface. Expressions applicable to all cases of skin-effect (normal, anomalous and intermediate) are obtained.
