Space Charge Behavior in Ethylene Propylene Rubber Under a 50-Hz AC Electric Field

open access: yesIEEE Access, 2019
In this study, the space charge behavior in ethylene propylene rubber (EPR) under a 50-Hz AC field is studied based on the variation of space charge response, FTIR spectra and impurity contents inside EPR with thermal treatment.

Comparison of the Purity and Impurity of Glucagon-for-Injection Products under Various Stability Conditions

open access: yesScientia Pharmaceutica, 2022
Glucagon is a polypeptide hormone that serves as an essential therapeutic agent in the emergency treatment of hypoglycemia. Recently, the first generic glucagon for injection was approved. However, unlike its brand name counterpart, which is produced via

Influence of Degassing Treatment on the Ink Properties and Performance of Proton Exchange Membrane Fuel Cells

open access: yesMembranes, 2022
Degradation occurs in catalyst inks because of the catalytic oxidation of the solvent. Identification of the generation process of impurities and their effects on the properties of HSC ink and LSC ink is crucial in mitigating them.

Numerical renormalization group calculation of impurity internal energy and specific heat of quantum impurity models [PDF]

open access: yes, 2012
We introduce a method to obtain the specific heat of quantum impurity models via a direct calculation of the impurity internal energy requiring only the evaluation of local quantities within a single numerical renormalization group (NRG) calculation for ...

Theoretical justification of reliability of threaded connections of cars during operation

open access: yesИнтеллект. Инновации. Инвестиции, 2020
The reliability of threaded connections is determined by the strength of their tightening, which, in particular, depends on the presence of defects and impurities in the material structure of the mated parts. In the case of intense vibrations, vibrations

Motion of a distinguishable impurity in the Bose gas: Arrested expansion without a lattice and impurity snaking [PDF]

open access: yes, 2016
We consider the real time dynamics of an initially localized distinguishable impurity injected into the ground state of the Lieb-Liniger model. Focusing on the case where integrability is preserved, we numerically compute the time evolution of the ...
