• #### Thermal conductivity of stishovite and of a homogeneous lower mantel composed of stishovite and periclase ﻿

(1970)
The cylindrical probe method of measuring the thermal conductivity of minerals (Horai and Simmons, 1969) is tested for quartz type Ge0 and found to be useful for measuring the thermal conductivity of germanates. By this ...

(1940)
• #### Thermal diffusion near a binary liquid azetrope ﻿

(1981)
Induction of a mass flux by a temperature gradient is known as the thermal diffusion or Soret effect, and is characterized by the thermal diffusion factor. A thermogravitational column’was used to obtain thermal diffusion ...
• #### Thermal energy collisions of potassium(nd) Rydberg atoms with electron-attaching molecules at intermediate n ﻿

(1990)
Thermal energy collisions of K(nd) Rydberg atoms with electron attaching molecules which result in reactions of the following types K(nd) + SF$\sb6$ $\to$ K$\sp+$ + SF$\sb6\sp-$ K(nd) + CF$\sb3$I $\to$ K$\sp+$ + I$\sp-$ + ...
• #### Thermal evolution of the eastern Serrania del Interior foreland fold and thrust belt, northeastern Venezuela, based on apatite fission track analyses ﻿

(2001)
Apatite fission track data show a gradual decrease in age (&sim;30 Ma to &sim;15 Ma) from north to the south in the eastern SerranIa del Interior, northeastern Venezuela. Based on a previous study, a model for the tectonic ...
• #### Thermal history, continental growth, and the Urey ratio: How continental growth affects the thermal evolution of the Earth ﻿

(2007)
Early thermal history models predicted a high Urey ratio (>0.7), in contrast to more recent geochemical estimates of 0.15-0.6. To potentially help resolve this discrepancy, we explore the effects of adding continental ...
• #### Thermal Lattice Boltzmann Simulation for Rarefied Flow in Microchannels ﻿

(2014-01-29)
This dissertation provides a detailed description of a new thermal lattice Boltzmann model capable of simulating temperature and velocity gradients within micro/nano-channels and vertical cavities in rarefied flow extending ...
• #### Thermal management in ceramics: Synthesis and characterization of a zirconia-carbon nanotube composite ﻿

(2002)
An investigation is conducted into the reduction of thermal conductivity in a porous ceramic through the inclusion of small amounts (1--3wt.%) of dispersed nanotube bundles and nanofibers. The thermal properties and thermal ...
• #### Thermal metamorphism of the organic matter in the Mancos Shale near Crested Butte, Colorado ﻿

(1973)
The area of this study is located in west central Colorado, near the town of Crested Butte. In this area, Cretaceous and Tertiary sedimentary rocks have been intruded by Tertiary igneous rocks. The results of previous work ...
• #### Thermal properties of frozen saline soils ﻿

(1984)
The thermal properties of three soils have been studied to ascertain the effects of saturating the soils with saline water. The frozen state is the primary area studied, although data during and after a phase change in the ...
• #### Thermal Remediation: Enhancing Ecosystem Recovery for Soils Contaminated with Heavy Hydrocarbons ﻿

(2017-11-30)
Terrestrial spills of crude oil and refined petroleum products have substantial environmental, economic, and public health consequences. Thermal treatment technologies hold an important niche in the remediation of ...
• #### Thermal response to ozone fluctuations in the stratosphere ﻿

(1978)
V/e have investigated the extent to which temperature fluctuations in the stratosphere, at low-latitude, are controlled by O3 absorption of solar and ground radiation. From a one dimensional model, we calculated the expected ...
• #### Thermochemical investigations of selected ternary strontium oxides and iridium-aluminum alloys by high temperature mass spectrometry ﻿

(1993)
A quadrupole mass spectrometer system was redesigned with pulse counting electronics and a resistively heated, high-temperature furnace. This system was employed in Knudsen effusion experiments to investigate the high ...

Interfacial phenomena are of vital importance to industrial and commercial applications from enhanced oil recovery to personal care products. To optimize interfacial processes, amphiphiles are usually involved, and, unlike ...
• #### Thermodynamic Modeling of Associating Fluids: Theory and Application ﻿

(2018-08-02)
The association interaction plays a significant role in self-assembly and determining the properties of associating fluids. The patch-patch attraction in patchy colloids, and hydrogen bonding are two examples of association. ...
• #### Thermodynamic Modeling of Branched Molecular Systems ﻿

(2019-04-17)
Presence of branches in the molecular structure results in properties different from that of linear molecules and also leads to special industrial value and diverse novel applications. However, a basic knowledge of ...
