Abstract: Firstprinciples calculations are performed to study the absorption spectra and electronvibration coupling of titaniumdoped sapphire (Ti:Al2O3). Geometry optimization shows a local structure relaxation after the doping of ...

Abstract: Monte Carlo simulations for photon transport are commonly used to predict the spectral response, including reflectance, absorptance, and transmittance in nanoparticle laden media, while the computational cost could be high. ...

Abstract: Recent advances in nanofabrication technology have facilitated the development of arrays of nanostructures in the classical or quantum confinement regime, e.g., singlewalled carbon nanotube (SWCNT) arrays with longrange ...

Abstract: In recent years, there has been interest in employing atomistic computations to inform macroscale thermal transport analyses. In heat conduction simulations in semiconductors and dielectrics, for example, classical molecular ...

Abstract: Metal nanoparticle has been a promising option for fillers in thermal interface materials due to its low cost and ease of fabrication. However, nanoparticle aggregation effect is not well understood because of its complexity. ...

Abstract: This work examines the impact of defects on the resonant response of singlewall carbon nanotube (CNT) resonators using classical molecular dynamics (MD) simulations. The work demonstrates that the presence of defects in ...

Abstract: Thermal properties and transport control are important for many applications, for example, low thermal conductivity is desirable for thermoelectrics. Knowledge of modewise phonon properties is crucial to identify dominant ...

Abstract: It was with great sadness that the heat transfer community learned of the passing of Professor Raymond Viskanta on December 27, 2021.Raymond Viskanta was born in Marijampole, Lithuania in 1931. In 1944, his family escaped ...
