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 properties of thermal insulation chambers
Textile Research Journal, 2020The paper presents the investigation of thermal properties of thermal insulation chambers as an actuator in intelligent clothing, having the property of automatically adjusting the thermal protection level. The chambers are designed to vary their thickness based on the pressure of the inflated air in them.

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.

Dynamic thermal environment and thermal comfort
Indoor Air, 2015Research has shown that a stable thermal environment with tight temperature control cannot bring occupants more thermal comfort. Instead, such an environment will incur higher energy costs and produce greater CO2 emissions. Furthermore, this may lead to the degeneration of occupants' inherent ability to combat thermal stress, thereby weakening 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.
