43. What is thermal expansion? B A. Is a decrease in the volume of a material when temperature decreases B. Is an increase in the volume of a material when temperature increases C. The transfer of thermal energy between materials by the collisions of particles D. The transfer of electric ...
A simple model is discussed based on the idea that the energetic match needed for energy and electron transfer occurs occasionally due to thermal fluctuations and that this match will not be achieved below a certain temperature. A mechanism based on exciton hopping in the aggregate followed by ...

Imbalanced Alfvénic turbulence is a universal process playing a crucial role in energy transfer in space, astrophysical, and laboratory plasmas. A fundamental and long-lasting question about the imbalanced Alfvénic turbulence is how and through w
Thermal-energy charge transfer of Ar+ with H2O: Internal and kinetic energy of the product H2O+ The reaction of Ar + with H 2O has been investigated at near-thermal energy. The product ions H 2O + and ArH + account for 90 and 10% of the total reaction... R Derai,S Fenistein,M...

Therefore, we interpret this migmatitic event as the signature of the crustal-scale thermal antiform associated with lithospheric thinning and the transfer of voluminous, asthenosphere-derived mafic–ultramafic magma10 (Fig. 8d). The monazite U–Pb age (c. 2700 Ma, sample 212070, Fig. 6b)...
A species with a D≪1 is said to be incompatible and will transfer easily into the melt, such as water (Katz et al. 2003), while compatible elements will remain in the solid phase. The concentration of a species in the melt will depend on its concentration in the mantle material, on...
It grows with hydrogen atom incidence energy and exhibits an energy-loss onset equal to the Ge surface bandgap. This leads us to conclude that hydrogen atom collisions at the surface of a semiconductor are capable of promoting electrons from the valence to the conduction band with high efficiency...
[30] reported improved stability and thermal performance of the Al2O3–TiO2–Cu/Water THNF as compared to the mono nanofluid. Zayan et al. [31] explained the rheological behaviour of the GO-TiO2–Ag/water THNF in terms of energy transfer phenomena. Sadaf et al. [32] reported the NPs ...
