The ability to engineer the thermal conductivity of materials allows us to control the flow of heat and derive novel functionalities such as thermal rectification, thermal switching and thermal cloaking. While this could be achieved by making use of composites and metamaterials at bulk length-scales, engineering the thermal conductivity at micro- and nano-scale dimensions is considerably more c...
Phonons can display both wave-like and particle-like behaviour during thermal transport. While thermal transport in silicon nanomeshes has been previously interpreted by phonon wave effects due to interference with periodic structures, as well as phonon particle effects including backscattering, the dominant mechanism responsible for thermal conductivity reductions below classical predictions s...
The purpose of this study is to examine the diffusion and thermal shock behaviour alternative dental silicates. samples derived from BaO-SiO2 system have been produced by melting process followed heat treatment. X-ray examinations indicated that amount orthorhombic sanbornite phase rised due treatment temperature as revealed peak intensities. alteration morphology was evident scanning electron ...
Abstract The present study provides a deep insight into the implications of sulphate addition on glass forming properties materials from SiO 2 –P O 5 –K O–MgO/CaO/MgOCaO systems, by combining: preliminary investigation as-synthesized (XRD, XRF, SEM–EDS), detailed characteristics their thermal behaviour (DSC), estimation various glass-stability parameters, in-depth analysis course crystallizatio...
