We propose a correction of the transmitted intensities in X-ray microscopy allowing improved quantification for polychromatic sources, particularly in tomographic reconstruction. The correction is based on the application of Beer's law for each energ

Conversion of an electron microprobe for use as an x‐ray microtomograph is described. Only minor modifications are required, indeed several of the utilities of the microprobe can be used to ensure high resolution radiography and tomography. System

Five nuclear microprobe modes of spectroscopy (NRA, DIGE, PIXE, PIGE, PESA) were combined to study the relationship between organic matter and mineral host matrix in oil-field environment. Sorption tests were conducted on various substrates, close to

X-Ray photoelectron spectroscopic studies of lanthanum oxide based oxidative coupling of methane catalysts, indicate a high binding energy O(1s) peak at 532.6–533.2 eV, which is strong evidence for surface superoxide (O2−) or peroxycarbonate (CO4

La 2 O 3 based oxidative coupling of methane catalysts have been studied by X-ray photoelectron spectroscopy. A high binding energy Ols peak at 532.6-533.2 eV, was found and is believed to be due to a peroxycarbonate species (CO 4 =). A surface equil
