X-Ray Diffraction Study on (+)-1,3,3-Trimethylbicyclo[2.2.1]heptan-2-one {(+)-Fenchone} (Z)-Oxime, Two Monochloro Derivatives and a Dehydrohalogenation Product.

Optimum driving a Z-pinch for soft X-Ray lasers

A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

Detection of breast cancer using non-invasive X-ray diffraction technique of hair: A preliminary study

Background: An early diagnosis of breast cancer relates directly to an accurate treatment plan and strategy. Early detection of breast cancer before its development would be a significant reduction of morbidity and mortality rates. The aim of this preliminary study is to investigate the sensitivity of Wide Angle X-ray diffraction (WAXRD) method on women hair samples of healthy and breast cancer...

Two-dimensional X-ray powder diffraction

X-ray diffraction study of Anodisc filters.

X-ray diffraction from Anodisc membrane filters is measured and analyzed. The patterns are consistent with pores of constant diameter and a Gaussian distribution of pore-pore spacing. The mean distance between pores, measured using x rays is 0.37 microm compared to 0.32 microm calculated from the nominal density of pores/cm(2). The results may be modeled both in terms of the convolution of a st...

High-pressure X-ray diffraction study on α-PbF2

The high-pressure behaviour of α-PbF2 has been investigated by angular-dispersive synchrotron X-ray powder diffraction up to 6.55(8) GPa. The fit of a 3-order BirchMurnaghan equation-of-state gave the volume at zero pressure V0=194.14(4) Å 3 and the bulk modulus b0=47.0(6) GPa with the pressure derivative b’=7.9(4). The continuous-symmetry-measure approach has been used for the quantification o...
