High Temperature Synthesis

2011
Abstract High temperature is an important means for inorganic syntheses of novel compounds, materials, and high-temperature phases. In this chapter, we highlight the various important aspects in high-temperature inorganic synthesis, along with their recent progress, such as preparation of rare earth compounds and materials at high temperature, sol ...

High-Temperature Microfluidic Lithography

Advanced Materials, 2002
The high-temperature microfluidic lithography was studied. A simple approach to improve the performance of microfluidic lithography, which does not act on the increase in the difference between the pressure that drives the capillary motion, but on the temperature-controlled reduction of the polymer viscosity was presented.

High-temperature sphalerons

Physical Review D, 1989
The SU(2) part of electroweak gauge theory has sphaleronlike configurations even in its symmetric phase (temperature {ital T}{gt}{ital T}{sub {ital c}}) which mediate baryon-number-violating processes. These sphalerons sit on top of a potential barrier (which we construct explicitly) whose height rises linearly with {ital T}, and always exceeds {ital T}

High temperature superconductivity

Journal of Polymer Science Part C: Polymer Symposia, 1970
AbstractThe critical temperature, Tc, for all presently known superconductors does not exceed 21'K. This fact obviously limits the range of applications of superconductivity in technology in a very fundamental way. On the whole, the reason why the value of Tc for “ordinary” superconductors would not exceed 20‐40oK is fairly well understood. At the same

High temperature tensiometry

1998
Publisher Summary This chapter presents after a short reminder of thermodynamic definitions, the most commonly used techniques for surface tension measurements with some details of the most interesting of them for high temperature applications. Some recent results on the evaluation of the influence of external factors, like the surrounding atmosphere,

High-temperature superconducting resonators

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1992
Preliminary measurements on high-T(c) superconducting resonators are reported and why they are attractive candidates for incorporation in low-noise oscillators is discussed. Some of the important contributions to oscillator noise are reviewed and how they depend on the resonator parameters is shown. A preliminary YBaCu (3)O(7)/LaAlO(3) resonator with a

High-temperature axion potential

Physical Review D, 1989
We investigate the possibility of new terms in the high-temperature axion potential arising from the dynamical nature of the axion field and from higher-order corrections to the {theta} dependence in the free energy of the quark-gluon plasma. We find that the dynamical nature of the axion field does not affect the potential but that the higher-order ...

High-temperature liquid chromatography

Journal of Chromatography A, 2003
The present state of the active use of elevated temperatures in liquid chromatography is reviewed, including the effects on retention, selectivity and efficiency. Separations in aqueous mobile phases as well as non-aqueous media are discussed, with particular emphasis on narrow-bore columns.

Superstrings at High Temperature

Physical Review Letters, 1985
The behavior of ten-dimensional superstrings at high temperatures is studied by use of the microcanonical ensemble. We focus on closed superstring theories. The massive string excitations alone have negative specific heat. Such a system can reach equilibrium with the zero modes of the string if the energy carried by zero modes is less than a given ...

High Temperatures

1996
Abstract ln this method electrical current is used to heat a sample placed in the DAC chamber. Liu and Bassett (1975) first studied melting of iron wire which was resistively heated in an ungasketed DAG. The phase diagram of iron was studied to pressures up to 43 GP a by Boehler et al. (1986) and up to 36 GP a by Mao et al.
