Lithium is one of the simplest metals, with negative charge carriers and a close reproduction of free-electron dispersion. Experimentally, however, Li is one of a handful of elemental solids (along with Cu, Ag, and Au) where the sign of the Seebeck coefficient (S) is opposite to that of the carrier. This counterintuitive behavior still lacks a satisfactory interpretation. We calculate S fully f...

The high-pressure melting curves of metals provide simple and useful tests for theories melting, as well important constraints the modeling planetary interiors. Here, we present an experimental technique that reveals latent heat fusion a metal sample compressed inside diamond anvil cell. combines microsecond-timescale pulsed electrical heating with internally-heated cell first time. Further, us...

Interfacial thermal conductance (ITC) affects heat transfer in many physical phenomena and is an important parameter for various technologies. The article considers the influence of mesoscopic effects on ITC, such as through gas gap, near-field radiative transfer, changes wetting behavior during melting. Various contributions to ITC liquid-solid interfaces processes fast pre-melting melting met...

A new analytical model for calculating the characteristics of primary cracks that appear in atomically smooth metals is proposed. technique has been developed length nanocracks based on study physical properties crystals. For first time, parameters were calculated using example metals. The results obtained basis method are compared with applying known models nanocrack formation. It shown our co...

The isothermal bulk modulus $$K_{{T_{m}}}$$ and surface tension γm of liquid metals at the melting point increase with decreasing atomic size a, these dependences are similar to one another. It is shown that transition a hexagonal closed-packed body-centered cubic structure concentrated above γm− regression line, face-centered below this line. In alkali, alkaline earth, rare earth metals, chang...

This article presents the temperature and emissivity estimation of metals around their melting points using different techniques, which are based on deterministic (ordinary least squares) Bayesian approaches. Linear non-linear models examined. The experimental data consist radiative fluxes at six wavelengths, collected by a pyrometer. apparatus is dedicated to characterization physical properti...
