Dear All, Could you please advice if you have the literatures on Applications of XRD/XRF in the oil industry.
Thank in advance for your help. Yours sincerely, and best wishes Husin Quoting Nicolae Popa <[EMAIL PROTECTED]>: > Hi, > > Besides strain and instrument also size broadening can be close to a > Gaussian if the crystallite size distribution is very narrow.
