An enhanced understanding of the microstructure of oxide ceramics will help scientists and engineers improve their efficiency and design. A phase-field model for the composition and phase distribution of the oxide ceramic components is studied. The model, which includes an obstacle in the phase portion of the energy potential, results in a minimisation problem that characterises the distributio...

The p–n junction i–u characteristic model is decisive for the accuracy enhancement of calibration-free temperature measurement. In this paper, we give a survey of adapted physically-based p–n junction i–u characteristic models, such as the Ebers–Moll2, the Ebers–Moll3, and the Gummel–Poon model. Furthermore, we build new models through polynomial extensions to the fundamental Shockley model. Th...

Abstract Emission of prompt gamma rays following (n,n’), (n,p) and (n,α) reactions induced by irradiation a calcium carbonate (CaCO 3 ) sample with beam fission neutrons was investigated modified version the FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) instrument operated at Heinz Maier-Leibnitz Zentrum (MLZ) in Garching. The neutron spectrum has an average energy 2.30 MeV position fast...
