naomi, I never said or implied that ITMO University and Laser Zentrum Hannover were not reputable, nor did I say or imply that about the Journal of Applied Physics. Those are the conclusions that you jumped to.
What I did say was that it is the assumptions made in the modelling which bother me. If any of them are wrong, the results will also be wrong. Until someone goes along to see if the theoretical results match those found by actual physical experiment, I'll leave it in the appropriate mental folder.
That aside, the use of nanoparticles based on a pyramid shape, which is part of what the study was about, might well have practical applications.
What I suspect is that having come to that conclusion, someone in the team wondered what the results would show if applied to the Great Pyramid. Making the assumptions they did produced a result which got the research a lot of publicity, which is never a bad thing for a scientific paper.
Cynical ? Moi ???
