There is nothing much to report about the replications. No positive results. Zhang was getting positive results. He found a problem with the pump, fixed it, and got more positive results. But lately the heat has petered out. I know of two or three other attempts. None has panned out yet. All of the replications I am aware of are somewhat different from Mizuno's setup. The cells are smaller, with less mesh. The methods of calorimetry are different. Two of them do not have mass spectrometers. I cannot say whether these differences matter. I think not having a mass spectrometer may be a problem.
Three samples of mesh have been sent to two high resolution mass spectrometers. I have not got any results back yet. The three samples of meshes are:
1. As received
2. Prepared with Pd but not used
3. Sample that produced a great deal of excess heat.
