beta irradiationoptically stimulated luminescence sensitivityannealingsensitivityluminescence lifetimeThe change in optically stimulated luminescence sensitivity of quartz associated with annealing is accompanied by a change in luminescence lifetime, whereas, in contrast, the change in sensitivity associated with ...
The alpha - beta transformation of berlinite (AlPO//4) at 586 degree C was studied by X-ray diffraction. Atomic displacements were obtained from results of least-squares refinement of data taken between room temperature and 600 degree C. The results suggest a rotational motion of the PO//4 ...
Graphene & Solar Technologies Limited engages in the development of high purity silica quartz products to produce semiconductors and photovoltaic solar panels in the United States. It is also involved in the development and commercialization of graphene materials and water harvesting products; and producti...
Thermodynamic quantities are calculated as a function of temperature by using Landau mean-field model for the $$\upalpha $$ – $$\upbeta $$ transition
Further, the company designs and fabricates application-specific crystals, lenses, prisms, mirrors, laser components, and substrates; and other custom and standard borosilicate, clear fused quartz, and synthetic fused silica glass products. It serves original equipment manufacturers of optical ...
By determining the mode Grüneisen parameter, the resonant frequencies are predicted in the vicinity of the \\(\\upalpha -\\upbeta \\) transition in quartz. This calculation is extended to low temperatures (down to about \\(50\\,^ {\\circ }\\hbox {C})\\), and the resonant ...
All experiments were carried out at room temperature using HELLMA quartz cells with Suprasil windows and an optical path length of 0.1 cm. All spectra were recorded in the wavelength range of 200–250 nm, using a band- width of 2 nm and a time constant of 2 s at a scan ...
Amyloid aggregation of α-synuclein (αS) is the hallmark of Parkinson’s disease and other synucleinopathies. Recently, Tau protein, generally associated with Alzheimer’s disease, has been linked to αS pathology and observed to co-localize in αS-rich
