Microwave photon - assisted tunneling in niobium triselenide,NbSe3.

Nonlinear conduction has been observed in NbSe₃ with microwave fields of amplitudes below the threshold field for nonlinear dc conduction at temperatures of about 25 K by the method of harmonic mixing. The observation is considered to support Bardeen's theory of tunneling assisted by photons whose frequency is the microwave frequency.     

Electron microprobe investigations on phase boundaries steel-enamel

Summary This report describes investigations carried out on a new type of enamel (Liberty Coat Enamel) for steel sheets from continuously cast material. Subsequent to technological tests, EPMA investigations were conducted to study the mechanism of enamel adherence. For this purpose, we employed our Concentration Mapping (CM) technique. In order to obtain representative data, a special evaluation method was used. The results, which are partly in contradiction with statements in the literature, suggest that the concept of enamel adherence reactions should be given further critical consideration.The paper has been presented at 12th Colloquium on Materials Analysis, Institute for Analytical Chemistry, Technical University in Vienna, May 13–15, 1985.
