A high-resolution hard x-ray microscope is described. This system is capable of detecting line features as small as 0.6 µm in width, and resolving line pairs 1.2-µm wide and 1.2-µm apart. Three types of two-dimensional image detectors are discussed and compared for use with hard x rays in high resolution. Principles of x-ray image magnification are discussed based on x-ray optics and diffractio...
Using of X-rays in different industries and especially in medical application is increasing. In this regard, designing of light and efficient protective material based on polymeric nanocomposites and precise study of the effect of adding nanoparticles with different sizes on the X-ray attenuation is necessary. In this study the epoxy nanocomposites with different percentages of copper oxide nan...
We report the thermal annealing-induced formation of ring-like structure of Zn(II)-doped magnetite from iron alkoxide leaf-like nanoplate precusor. The phase, structure and morphology of magnetite nanorings were comprehensively characterized by powder X-ray diffraction, X-ray photoelectron spectroscopy, atomic force microscope, scanning electron microscope, and transmission electron microscope....
