I have read the paper. All results are excellent. But I am confused about the transition temperature of 320 K. How it could be possible? All the figures are not high quality and clear. I think something may be wrong in the measurement. Or if true, author should provide more information about the measurement.
This paper is OK. All results are excellent. But I am also confused about the transition temperature of 320 K and the quality of presentation is no good.
This paper has to confront peer reviewers and the results have to be reproduced by independents groups before being taken seriously. In my opinion it is highly unlikely that a gold-silver mixture could be superconducting above temperature of few kelvins.
