Features of calcium hexaaluminate formation in alumina-zirconia ceramics

open access: yesChimica Techno Acta, 2023
Alumina-zirconia composites containing calcium hexaaluminate in the amount from 0 to 15 wt.% were investigated. The materials were obtained by water dispersion, granulation, axial pressing, and free sintering. Density and open porosity were determined by

The synchrotron peak shift during high-energy flares of blazars [PDF]

open access: yes, 1999
A prediction for the energy shift of the synchrotron spectrum of flat-spectrum radio quasars (FSRQs) during high-energy flares is presented. If the $\gamma$-ray emission of FSRQs is produced by Comptonization of external radiation, then the peak of the ...

Extendible-energy synchrotrons [PDF]

open access: yesNuclear Instruments and Methods, 1967
Abstract Synchrotron guide-field arrangements have been developed that provide for a convinient and economical later increase in energy by the addition of components omitted in the initial construction. Criteria for the design of such an accelerator include new considerations such as emphasis on small circumference to reduce initial costs and on ...

Glycoscience@Synchrotron: Synchrotron radiation applied to structural glycoscience [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2017
Synchrotron radiation is the most versatile way to explore biological materials in different states: monocrystalline, polycrystalline, solution, colloids and multiscale architectures. Steady improvements in instrumentation have made synchrotrons the most flexible intense X-ray source.

SYNCHROTRON POLARIZATION IN BLAZARS [PDF]

open access: yesThe Astrophysical Journal, 2014
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for gamma-ray blazars. Our calculations employ a full 3D radiation transfer code, assuming a helical magnetic field throughout the jet.

Volcanoes Erupt Stressed Quartz Crystals

open access: yesGeophysical Research Letters, 2019
Volcanic eruptions are energetic events driven by the imbalance of magmatic forces. The magnitudes of these forces remain poorly constrained because they operate in regions that are inaccessible, either underground or dangerous to approach.
