However, under the condition of vacuum and specific temperature, alkali metals is gaseous state, and the chemical thermodynamis principle demonstrates that the displacement reaction is spontaneous. In conclusion, the lowest temperature, which manufacture K、Na、Rb、Cs by displacement reaction is 992.4℃、896.7℃、845.9℃、879.8℃ respectively.
In fact, about 60% of consump t ion of annual fertilizer N were lost from gaseousness and agriculture non-point sources, this is a key factor to control the high content inorganic N in the Cha ngjiang River mouth.
Iodine species in the gas phase in real air samples has been determined in two field campaigns at the west coast of Ireland, indicating that gaseous iodo-hydrocarbons and elemental iodine are the precursors of new particle formation.
A seaweed-chamber experiment was performed, indicating that gaseous I2 is one of the important precursors that lead to new particle formation in the presence of solar light in the ambient air at the coastal tidal area.
Denitrification is generally referred to as the microbial reduction of nitrate to nitrite and further gaseous forms of nitric oxide, nitrous oxide and molecular nitrogen.
They are functionally interconnected processes in the soil nitrogen cycle that are involved in the control of long-term nitrogen losses in ecosystems through nitrate leaching and gaseous N losses.
This process is based on a solid-gas eutectic reaction involving a gaseous medium and a metal or ceramic phase.
Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics
The explicit solution to Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics is given.
Photocatalytic Oxidation of Aniline in the Gas Phase Using Porous TiO2 Thin Films
The gas-phase photocatalytic oxidation of aniline on a new kind of porous nano-TiO2 composite films is investigated.
Acetone solution-casting films of poly(methylmethacrylate) were analyzed by differential scanning calorimetry and pyrolysis gas chromatography-mass spectroscopy under natural evaporation and ultrasonic vibration, respectively.
In comparison with the gaseous state, the splitting Δv = vX, Y - vZ in the argon matrix decreases to 18.45 cm-1, whereas, in the nitrogen matrix, the band vX, Y is split into components vX and vY, with the splitting being equal to δ ≈ 0.9 cm-1.
The calculated frequencies vZ, vX, and vY of a dimer in the matrix are shifted toward smaller frequencies as compared to the gaseous state, while the resonance splitting decreases virtually by 2 cm-1.
The term complex plasma is used for a state where some components (dust) are in crystal or liquid state, while the others (electron, ions, and neutral atoms) are in gaseous state.
This paper continues a series of review papers devoted to the physics of complex plasmas, in which one of the components (dust) is in a crystalline or liquid state, while the others (electron, ions, and neutral atoms) are in a gaseous state.
