Temperature Dependence of the Electron Paramagnetic Resonance Spectrum of Asphaltenes from Venezuelan Crude Oils and Their Vacuum Residues
(American Chemical Society, 2019-01)
The electron paramagnetic resonance (EPR) technique is used to evaluate the temperature dependence of the aggregation processes in asphaltenes of heavy and extra-heavy crude oils and their vacuum residues from the Venezuelan ...
Mechanisms underlying photosynthetic acclimation to high temperature are different between Vitis vinifera cv. Syrah and Grenache
(Csiro Publishing, 2021-02)
Photosynthesis acclimation to high temperature differs among and within species. Grapevine intra-specific variation in photosynthetic acclimation to elevated temperature has been scarcely assessed. Our objectives were to ...
Thermal properties of 2:1 bismuth borate: Temperature-dependent characterizations of lone electron pairs
(Wiley Blackwell Publishing, Inc, 2018-11)
Applications of bismuth borate ceramics require understanding of the microscopic features, leading to macroscopic behaviors such as thermal expansion. We report the structural and spectroscopic features of Bi4B2O9 between ...
Mechanical energy losses in plastically deformed and electron plus neutron irradiated high purity single crystalline molybdenum at elevated temperatures
(Wiley VCH Verlag, 2012-10)
Mechanical spectroscopy (MS) and transmission electron microscopy (TEM) studies have been performed in plastically deformed and electron plus neutron irradiated high purity single crystalline molybdenum, oriented for single ...
Fabrication of hot-wire probes and electronics for constant temperature anemometers
(Planta Piloto de Ingeniería Química, 2010-03)
The purpose of this paper is to discuss the construction of constant temperature hot wire anemometers. Different options are analyzed for the fabrication of sensors and electronics. A practical and simple method is developed ...
Temperature and electron density gradient in Xe laser produced plasmas, by spectral analysis
(Pergamon-Elsevier Science Ltd, 2000-03)
We have performed a spectroscopic analysis on laser produced plasmas in Xe at intermediates pressures (less than 1 atm), resolved both spectrally and temporally, also discriminating different regions of the plasma. This ...
Low-temperature impedance spectroscopic analyses of ceramic electrodes based on Mo and Co co-doped SnO2
(University of Novi Sad, Faculty of Technology, 2019-11)
Low resistive electrodes based on Co and Mo co-doped SnO2 were prepared by the conventional solid-state reaction and sintered at 1250 °C for 2 h. Concentration of Co2O3 precursor was unchanged (1 mol%), while MoO3 was ...
On the use of the double floating probe method to infer the difference between the electron and the heavy particles temperatures in an atmospheric pressure, vortex-stabilized nitrogen plasma jet
(American Institute of Physics, 2014-05)
Sweeping double probe measurements in an atmospheric pressure direct current vortex-stabilized plasma jet are reported (plasma conditions: 100 A discharge current, N2 gas flow rate of 25 Nl/min, thoriated tungsten rod-type ...
Electronic Fine Structure in the Electron-Hole Plasma in SrB6
(American Physical Society, 2000-07)
Electron-hole mixing-induced fine structure in alkaline earth hexaborides leads to lower energy (temperature) scales, and thus a stronger tendency toward an excitonic instability than in their doped counterparts (viz. ...
