Absorption and electro-absorption (Stark effect) spectra of polycrystalline and lyophillized samples of pheophorbides and bacteriopheophorbides have been measured in order to obtain information on the...
Analysis of 53 bulk powders derived from various rocks of the Upper Floridan Aquifer reveal calcite, dolomite/ankerite, quartz, apatite, and smectite to be the dominant minerals, with the clay and apa...
Prior to DSDP Leg 17, no sites drilled in the central Pacific had continuously cored a thick section of pelagic brown clay. On Leg 6 several sites were drilled through brown clay, but poor recovery du...
Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements provide unprecedented insights into mineral behaviors and mechanisms of crystal structure transformat...
A periodical unevenness of the running surface of rails is formed on ascending slope of submarine railway tunnel. One of the causes has been concluded due to the combination of a low friction and whee...
The leather industry creates a large quantity of organic and inorganic waste containing chromium. This research examines stabilization of particulate tannery waste in type II Portland cement. Several ...
Resonant soft x-ray scattering experiments with photon energies near the O K and the Cu L3 edge on the system La1.8−xEu0.2SrxCuO4 for 0.1  x  0.15 are presented. A phase diagram for stripe-l...
SiGe islands are used to induce tensile strain in the Si channel of Field E ect Transistors to achieve larger transconductance and higher current driveabilities. We report on x-ray di raction experime...
Diffraction enhanced imaging (DEI) with edge enhancement is suitable for the observation of weakly absorbing objects. The potential ability of the DEI was explored for displaying the microanatomy and ...
Two independent groups of physicists have found a new way to get high-definition glimpses of the innards of living cells. The technique uses X-ray diffraction microscopy on cells frozen below –170 °C,...
Rietveld refinements using synchrotron powder X-ray diffraction data were used to study the crystal structure and dehydration behavior of pure monoclinic palygorskite samples from Korea and Alaska. Th...
Poly (methyl methacrylate) -- PMMA -- and poly (methacryloyl chloride) -- PMACl -- were synthesized by free radical solution polymerization. The thermal stabilities of these polymers were determined w...
X-ray powder diffraction patterns and infra-red absorption spectra have been evaluated and analysed for the Y1 Ba2 Cu3 O7-d - Gex compound samples prepared by the solid state reaction with x values ra...
The maximum superheating of a solid prior to melting depends on the effective dimensionless nucleation energy barrier, heterogeneities such as free surfaces and defects, and heating rates. Supe...
Abstract: An internal standard X-ray diffraction (XRD) analysis technique permits reproducible and accurate calculation of the mineral contents of rocks, including the major clay mineral families: Fe-...
