A scenario for the Galactic cosmic rays between the knee and the second-knee
(IOP Publishing, 2019-03-07)
We perform a fit to measurements of the cosmic ray spectrum in the energy range between 10 15 eV and 10 18 eV using data from the TALE, Tunka and Auger experiments. We also fit the data on the depth of shower maximum, X ...
Grazing-incidence Xrf Analysis Of Layered Samples: Detailed Study Of Amplitude Calculation

TiO2-Cu photocatalysts: A study on the long- and short-range chemical environment of the dopant
(2013-06-01)
In this study, the short- and long-range chemical environments of Cu dopant in TiO2 photocatalyst have been investigated. The Cu-doped and undoped TiO2 specimens were prepared by the sol-gel approach employing CuSO4·5H2O ...

Ethanol electro-oxidation in an alkaline medium using Pd/C, Au/C and PdAu/C electrocatalysts prepared by electron beam irradiation
(2013-09-11)
Carbon-supported Pd, Au and bimetallic PdAu (Pd:Au 90:10, 50:50 and 30:70 atomic ratios) electrocatalysts were prepared using electron beam irradiation. The obtained materials were characterized by energy dispersive X-ray ...

X-ray/UV/optical variability of NGC 4593 with Swift: Reprocessing of X-rays by an extended reprocessor
(Oxford University Press, 2018)
We report the results of intensive X-ray, UV, and optical monitoring of the Seyfert 1 galaxy
NGC 4593 with Swift. There is no intrinsic flux-related spectral change in any variable
component with small apparent variations ...
Black and green pigments based on chromium-cobalt spinels
(Elsevier B.V. Sa, 2011-09-15)
Chromium and cobalt oxides are widely used in the manufacture of industrial pigments. In this work, the Co(Co(2-x)Cr(x))O(4) powders with different chromium concentrations (x = 0, 0.25 and 1) were synthesized by the polymeric ...

Crystallization and preliminary X-ray crystallographic studies of Protac (R), a commercial protein C activator isolated from Agkistrodon contortrix contortrix venom
(Elsevier B.V., 2005-09-25)
The protein C pathway plays an important role in the control and regulation of the blood coagulation cascade and prevents the propagation of the clotting process on the endothelium surface. In physiological systems, protein ...
