It is clear that, here, in the samples, there are two conductivity behaviors of metal and semiconductor at different temperature ranges. In the work [1], the electrical conductivity of LaFeO3 was not measured below 600K because of the high electrical resistance of the sample. In our work, for the first time, the transition of “metallic-semiconductor” conductivity behavior was observed at the high temperature (300K-600K) in the very high resistivity perovskite compound.

Nanostructured Materials

Annealing at high temperature (700°C) results in the formation of a stable triple point struc- ture with additional coarsening of the grains within the layers ( Figure 3.22c. High pressure torsion of NiTi leads to amorphization of the alloy [151. A comprehensive review of the literature has not been attempted.. One of the reasons for the overpotential is the fi nite rate of the reaction at the electrodes.

Preparation and characterization of nanocomposite TiO2/SnO2 films

tainguyenso.vnu.edu.vn

These dopant atoms at high temperature and for a long time annealing experienced an oxidation, which resulted in the decrease of photo effect as shown in Fig. The existence of two conflicting processes is the reason of the maximal photo effect during the annealing time.. The nanocomposite TiO 2 /SnO 2 films have been prepared via two steps of spray pyrolysis for TiO 2 and sol-gel for SnO 2 .

Investigation of MnO2-Co3O4-CeO2 activity after aging under H2O and SO2 at high temperature showed that the catalytic activity at low reaction temperature decreased significantly after aging but remained at high temperatures (>250 oC). The catalyst MnO2-Co3O4-CeO2 1-3-0.75 not only remained its catalytic activity at high temperature above 500 oC but also converted CO and C3H6 at low temperature after activation in the flow with a O2/CO molar ratio of 1.6 at 100 oC.

Sorbitol was synthesized from glucose by hydrogenation at high temperature and pressure, by the batch method using catalyst Nickel - Raney. The effect of the parameter such as: temperature (T), pressure (P) and reaction time (t) were studied by the optimization process. The obtained equation from the optimization model as follows: Y T + 8.43478P + 4.83702t - 7.64256P2 The obtained optimizing point are Topt = 1480C.

Aircraft propulsion

Functions of the nozzles are to convert high-pressure, high-temperature energy (enthalpy) to kinetic energy and to straighten the flow so that it exits in the axial. Because of the high temperatures that a nozzle experiences materials used in nozzle construction are experiences, materials used in nozzle construction are usually a nickel-based alloy, titanium alloy, or ceramic composite p.

Using the reduced La(Co,Cu)O3 nanoperovskites as catalyst precursors for CO hydrogenation

tainguyenso.vnu.edu.vn

O 2 -TPD spectra show two typical peaks with a strong shoulder at a high temperature for Co-Cu based perovskites. In the case of the free-copper catalysts, a large peak with a long tail at a lower temperature of oxygen desorption is observed in the broad temperature range of 400-650 o C as depicted in Fig. The lower temperature peak, namely preferred to as α-oxygen, is attributed to oxygen species weakly bound to the surface of the perovskite-type rare-earth cobaltate.

These terms characterize various plasmas ranging from relatively high-pressure gases with a small fraction of the atoms ionized and relatively low charged-particle temperatures. for example, plasmas used in computer-chip processing and light sources. to those in very low density gases with a large fraction of the gas atoms ionized and very high-temperature charged particles. for example, fusion plasmas. Different types of plasmas underlie different applications and different natural phenomena.
