Melting temperature of unrelaxed amorphous silicon

Physical Review B, 1991
Direct picosecond laser measurements of the critical fluence for melting have been performed, showing unambiguously a 30% increase in the energy density required for surface melting of relaxed compared with unrelaxed amorphous silicon (a-Si). The difference in optical coupling cannot account for this variation, which can only be explained in terms of ...

Tin in granitic melts: The role of melting temperature and protolith composition

Lithos, 2018
Granite bound tin mineralization typically is seen as the result of extreme magmatic fractionation and late exsolution of magmatic fluids. Mineralization, however, also could be obtained at considerably less fractionation if initial melts already had ...

Melting Temperatures of Copolymers

Journal of Applied Physics, 1966
The melting temperatures (532° to 580°K) of copolymers of tetrafluoroethylene and hexafluoropropylene have been measured on a microscope hot stage. The copolymers had concentrations of perfluoromethyl groups between 0.0275 and 0.075 groups per carbon atom and lamella thicknesses which varied from 340 to 500 Å independently of comonomer concentration ...

High-temperature mechanical properties of AlSi10Mg specimens fabricated by additive manufacturing using selective laser melting technologies (AM-SLM)

Additive Manufacturing, 2018
Mechanical properties (tensile strength and creep) of AlSi10Mg specimens fabricated by selective laser melting (SLM) in the Z-direction were investigated in the 25-400 °C temperature range. Specimens were tested after stress relief treatment. The results

Melting temperature and periodicity

Journal of Applied Physics, 1981
The temperature of melting Tf for most metals can be related to bond distance d, the number of electrons per atom (V) in an sp, sd, or sf band, and electron interactions through a parameter K3≡Tfd2/V. The value of this parameter varies systematically with the quantum states of the elements or their positions in the periodic table.

Melting of 𝜌2 meson at extreme temperatures

AIP Conference Proceedings, 2019
The thermal properties of the light tensor ρ2 meson with quantum numbers JPC = 2−− are studied at finite temperature. In our calculations, two-point Thermal QCD sum rules approach is employed including contributions up to operator dimension-5 of quark, gluon, and quark-gluon mix condensates.

High-temperature metamorphism and crustal melting: working with melt inclusions

Periodico di Mineralogia, 2015
The application of melt inclusion (MI) studies to migmatitic and granulitic terranes is a recent, small-scale approach for a better understanding of melting in the continental crust. In order to show the role of anatectic MI in providing a wealth of microstructural and compositional information on high-temperature metamorphism and crustal anatexis, we ...

Melting temperature of surface-tethered DNA

Analytical Biochemistry, 2010
A method for the accurate determination of the melting temperature (T(m)) of surface-immobilized DNA duplexes that exploits the fluorescence-quenching properties of gold is reported. A thiolated single-stranded DNA probe is chemisorbed onto a gold surface and then hybridized to a fluorophore-labeled complementary sequence.

On the melting temperature of nanoparticles

Glass Physics and Chemistry, 2008
A theoretical explanation is offered for the possibility of melting a nanoparticle at a higher temperature as compared to the melting temperature of a macroscopic sample of the same chemical composition. The special attention is focused on the analogy between the temperature range ΔTm of melting of nanoparticles and the softening range for glasses.

MODELING THE MELTING TEMPERATURE OF METALLIC NANOWIRES

Modern Physics Letters B, 2010
A model is developed to account for the size-dependent melting temperature of pure metallic and bimetallic nanowires, where the effects of the contributions of all surface atoms to the surface area, lattice and surface packing factors and the cross-sectional shape of the nanowires are considered.
