Anisotropy in clay-rich sedimentary rocks is receiving increasing attention. Seismic anisotropy is essential in the prospecting for petroleum deposits. Anisotropy of diffusion has become relevant for environmental contaminants, including nuclear waste. In both cases, the orientation of component minerals is a critical ingredient and, largely because of small grain size and poor crystallinity, t...

Figure S1. Rietveld refinement patterns of PCN-888 using synchrotron PXRD data (λ = 0.72768Å): observed (blue), calculated (red), and difference (grey) profiles are shown; the tick marks below the curves indicate Bragg positions. The X-ray diffraction pattern between 1.1° and 4.2° is magnified in the inset. The full pattern shows a precise match between the experimental PXRD data and those simu...

The power of the state-of-the-art neutron powder diffractometer suite at the Institut Laue–Langevin for investigating the structure of nondeuterated materials is presented using gypsum, CaSO4 2H2O, as a reference material. It is shown that flexible modern neutron powder diffraction instruments at reactorbased sources can yield data with sufficient counting statistics above the incoherent scatte...

the safe and effective management of radioactive waste has been given utmost importance from the very inception of nuclear industry in india and it covers the entire range of activities from handling, treatment, conditioning, transport, storage and finally disposal. radioactive waste is generated at various stages of the nuclear fuel cycle, which includes the mining and milling of uranium ore, ...

In this paper, MgB2 bulks were prepared with doped TiO2 nanoparticles surface-modified by 5-10% SiO2. Quantitative X-ray diffraction (XRD) analysis was performed to obtain the weight fraction of impurities using the Rietveld method. The effects of addition of TiO2/SiO2 nanoparticles on the critical temperature (Tc), the upper critical field (Hc2), and the irreversibility field (Hirr) as a funct...
