Thermalization and Thermal Transport in Molecules
The Journal of Physical Chemistry Letters, 2016The nature and rate of thermal transport through molecular junctions depend on the length over which thermalization occurs. For junctions formed by alkane chains, in which thermalization occurs only slowly, measurements reveal that thermal resistance is controlled by bonding with the substrates, whereas fluorination can introduce thermal resistance ...

Thermal control in graphene nanoribbons: thermal valve, thermal switch and thermal amplifier
Nanoscale, 2012We study the thermal transport in graphene nanoribbons by using nonequilibrium molecular dynamics simulations. It is reported that the three-terminal graphene nanoribbons can perform some functions of thermal devices such as thermal valve, thermal switch and thermal amplifier. Electronic devices have transformed almost all aspects of our lives.

To thermalize, or not to thermalize?
Science, 2016Statistical Physics Intuition tells us that an isolated physical system subjected to a sudden change (i.e., quenching) will evolve in a way that maximizes its entropy. If the system is in a pure, zero-entropy quantum state, it is expected to remain so even after quenching. How do we then reconcile statistical mechanics with quantum laws?

Thermal Contact and Thermal Isolation [PDF]
, 1992 In any low-temperature apparatus it is necessary to couple some parts thermally very well whereas other parts have to be well isolated from each other and, in particular, from ambient temperature. The transfer of “heat” (or better “cold”) and the thermal isolation are essential considerations when designing a low-temperature apparatus.

Thermal Stress and Thermal Comfort
Ergonomics, 1973The factors which determine the level of heat stress and the difficulties inherent in its measurement are discussed. The degree of thermal comfort or discomfort is shown to he a useful measure of thermal stress and methods for the determination of the preferred temperature are described.

Thermal runaway by thermal analysis
Thermochimica Acta, 1990Abstract The effect of heating rate on thermal runaway has been investigated by thermal analysis. For the materials studied in the present work there was an increase in the ignition temperature as the heating rate was increased. At high heating rates the effect was largely determined by the thermal relaxation time.

Thermal Expansion of Thermally Sprayed Coatings [PDF]
International Thermal Spray Conference, 1998 Abstract The coefficient of thermal expansion (CTE) of a NiCoCrAlY coating was investigated in this work. The CTE was inferred from the measured length variations of coated prismatic symmetric specimens (i.e. having the coating on two opposite surfaces) at various temperature increments.

Thermal Losses/Thermal Inertia
1986Quantifying the loss stair-step has been one of the important goals of the evaluation team at the SSPS project. This evaluation area addresses each of the loss elements as they were evaluated, and also discusses one of the interesting realizations that resulted from this evaluation — thermal inertia, a major hinderance to successful solar thermal ...

Thermal Fatigue and Thermal Shock
1964Problems in the strength of structural materials in a variable temperature field are attracting more and more attention from engineers, as well as from investigators working in the most diverse branches of technology. A number of reviews [1–3] have appeared recently and are used in the present paper.
