We have demonstrated for the first time the application of a small angle neutron scattering (SANS) technique for the precise determination of the onset of hydrocarbon transport (primary migration) in shaly source rocks. We used a sequence of rocks py

The analysis of small- and ultra-small-angle neutron scattering data for sedimentary rocks shows that the pore-rock fabric interface is a surface fractal (D{sub s}=2.82) over 3 orders of magnitude of the length scale and 10 orders of magnitude in int

Liquid ${\mathrm{Zr}}_{46.8}{\mathrm{Ti}}_{8.2}{\mathrm{Cu}}_{7.5}{\mathrm{Ni}}_{10}{\mathrm{Be}}_{27.5}$ has been studied by quasielastic neutron scattering. The microscopic dynamics of this bulk glass forming alloy deviates qualitatively from simpl

Incoherent neutron-backscattering and field gradient NMR are combined to measure the self-correlation function of protons in glycerol. Extensive simulations reveal and delimit systematic effects of multiple scattering. At microscopic wave numbers, ta

The structure of the intermetallic alloy (the high-temperature phase) has been studied by means of neutron diffraction. Alloys with Ni contents between 71 and 75 at.% were examined at temperatures ranging from 600 to . The results confirm structure a

Nickel diffusion in structure, four sublattices) is so fast that an unusual jump mechanism might be suspected. This suspicion is nourished by the recent discovery of high concentrations of ordered vacancies, i.e. vacancies on two of the nickel sublat

The phonon dispersion of iron-rich Fe-Si alloys of D03 structure (space group Fm-3m) has been studied by inelastic neutron scattering. The measurements were carried out on two crystals of different composition: Fe75Si25 at 20 and 930 degrees C, and F

Nickel diffusion in the high-temperature phase of the intermetallic alloy Ni3Sb is extremely fast compared to diffusion in other intermetallics. We have studied quasielastic neutron scattering, which permits us to determine the elementary diffusion m

Ni diffusion in the hexagonal NiSb intermetallic phase of approximately equiatomic composition is surprisingly fast, more than two orders of magnitude faster than Sb diffusion. In order to determine the atomic jump mechanism of the Ni atoms, quasiela
