Barium based ferroe…
Ductile metals and other materials typically deform plastically under large applied loads; a behavior most often modeled using plastic deformation constitutive models. However, it is possible to capture some of the key behaviors of plastic deformation using only the framework for nonlinear elastic mechanics. In this p…
This paper describes the knowledge advancements from the uncertainty analysis for the State-of- the-Art Reactor Consequence Analyses (SOARCA) unmitigated long-term station blackout accident scenario at the Peach Bottom Atomic Power Station. This work assessed key MELCOR and MELCOR Accident Consequence Code System, Ver…
In this work we present a theoretical analysis of plasmon nanoantennas for a diamond cluster\ncontaining a bright NV center. The results are obtained by the numerical simulations using the discrete\ndipole approximation. A gold shell around the diamond core is considered as antenna. It is shown\nthat by varying the si…
In this paper the fabrication and precipitation hardening behavior of bulk nanostructure Al7075 alloy is investigated. In order to produce this alloy, the elemental powder based on the nominal composition of conventional Al7075 alloy is milled up to 15 h and then hot pressed. The milled and hot pressed samples are cha…
In the present investigation, LiNbO3 dispersed Li2CO3 composite of varying volume fraction is prepared. Its validity of placement in ionic conductor is verified by determining ionic transference number by Wagner’s dc polarization technique and bulk electrical conductivity is estimated with complex impedance spectrosco…

We applied the discrete element method (DEM) to analyze the normal impact properties of elastoplastic spherical particles. DEM simulation of impact between two identical elastoplastic spheres is carried out to validate the proposed model. The numerical results show well agreement with the FEM solution. Based on this m…
Abstract : Benchmark and validation studies are presented that quantify the accuracy of computational models. An important factor in these studies is the ability to compare simulated impedance results with experimental data. In a majority of differential benchmark studies the data acquisition is handled by a commercia…

Abstract Photoluminescence (PL) efficiencies were estimated for individual silicon‐doped GaN nanowires grown by plasma assisted molecular beam epitaxy (PAMBE). Steady‐state PL measurements reveal efficiencies that depend on excitation intensity, temperature, and nanowire morphology. While many nanowires had their best…
