Thermal diffusion causes isotope fractionation in firn when there is rapid temperature variation, creating isotope differences which are captured in bubbles when ice is created at the base of firn.

Thermal diffusion may refer to:

* Thermal diffusion, an obsolete method of uranium enrichment

Thermal conductivity is directly traceable to the material's porous, air-cell construction which effectively traps air or a gas in the maze of minute bubbles which form its composition.

Thermal radiation refers not only to the radiation itself, but also the process by which the surface of an object radiates its thermal energy in the form black body radiation.

Ocean Thermal Energy Conversion ( OTEC ) uses the temperature difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work, usually in the form of electricity.

Thermal grease is usually white in colour since these ceramics are all white in powder form.

Thermal lows form due to localized heating caused by greater sunshine over deserts and other land masses.

Thermal lows form due to localized heating caused by greater sunshine over deserts and other land masses.

The Thermal Contraction Theory states that during the winter months, thermal contraction cracks form only a few cm wide and a couple of metres deep because of the extreme cold weather.

Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body.

Thermal mass is a concept in building design that describes how the mass of the building provides " inertia " against temperature fluctuations, sometimes known as the thermal flywheel effect.

The Thermal Observation and Gunnery Sight II ( TOGS II ), from Thales, provides night vision.

The Raichur Thermal Power Station at Shaktinagar in this district provides a large portion of the electricity consumption in Karnataka.

The lighthouse provides a panoramic view of a portion of the 1, 269 hectare Cape Bolinao Dendro Thermal Ipil-Ipil Plantation

Thermal transfer printing is a digital printing process in which material is applied to paper ( or some other material ) by melting a coating of ribbon so that it stays glued to the material on which the print is applied.

Thermal CTP involves the use of thermal lasers to expose and / or remove areas of coating while the plate is being imaged.

Thermal reactors generally depend on refined and enriched uranium.

The end of the Paleocene ( 55. 5 / 54. 8 Mya ) was marked by one of the most significant periods of global change during the Cenozoic, the Paleocene-Eocene Thermal Maximum, which upset oceanic and atmospheric circulation and led to the extinction of numerous deep-sea benthic foraminifera and on land, a major turnover in mammals.

Thermal radiation is a common synonym for approximately black body radiation spontaneously emitted from objects, that is chiefly infrared electromagnetic radiation at temperatures often encountered on Earth.

** M551A1 TTS-Tank Thermal Sight, fitted with the AN / VSG-2B thermal sight unit, similar to the unit used on the M60A3 MBT.

Thermal control was achieved through the use of adjustable louvers on the sides of the main compartment.

Thermal imaging can be used to document areas of poor thermal performance such as the negative thermal impact of roof-angled glass or a skylight on a cold winter night or hot summer day.

Thermal insulation on the Huygens probe

Thermal inertia of the structure is very high because the mass is insulated on both sides.

" Thermal conductivity is a material property that is primarily dependent on the medium's phase, temperature, density, and molecular bonding.

Thermal control was planned to be achieved by a large number of small " propeller blade " devices on the surface of the sphere.

Thermal control was planned to be achieved by fifty small " propeller blade " devices on the surface of the sphere.

Two second-generation techniques are currently in development: Thermal Assisted Switching ( TAS ), which is being developed by Crocus Technology, and spin-transfer torque ( STT ) on which Crocus, Hynix, IBM, and several other companies are working.

In 1979, Jarvis became the Power / Thermal / Harness Subsystem Engineer on the LEASAT Program.

Thermal imaging cameras are widely used to complement new or existing security networks, and for night vision on aircraft, where they are commonly referred to as " FLIR " ( for " forward-looking infrared ".

Thermal noise in an idealistic resistor is approximately white, meaning that the power spectral density is nearly constant throughout the frequency spectrum ( however see the section below on extremely high frequencies ).

Thermal radiation in visible light can be seen on this hot metalwork.

Their velocities relative to a spacecraft in orbit can be on the order of kilometers per second, and resistance to micrometeoroid impact is a significant design challenge for spacecraft and space suit designers ( See Thermal Micrometeoroid Garment ).

On 19 April 2005, leaked radioactive waste was discovered from ThORP ( Thermal Oxide reprocessing plant ) through a crack into a sump chamber which may have started as early as August 2004, and was categorized as a level 3 event on the International Nuclear Event Scale, resulting in fines.

Thermal soak aerodynamic heat shield used on the Space Shuttle.

Thermal radiation accounts for between 35-45 % of the energy released in the explosion, depending on the yield of the device.
