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.
      
A series of methodologies for the measurements of iodine species in the gas and particle phases of the coastal atmosphere has been developed.
      
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.
      
Determining the relative age of blue ballpoint ink by gas chromatography
      
The content of the volatile components in blue ballpoint pen ink were determined by gas chromatography (GC).
      
Compared with the results obtained by GC/qMS only, the analytical results obtained by these hyphenated methods of gas chromatography are more credible.
      
Polysulfone nanofibers prepared by electrospinning and gas/jet-electrospinning
      
The electrospinning equipment was designed in a new way, wherein the spinneret was combined with a gas jet device.
      
The gas used in this gas jet/electrostatic spinning was nitrogen.
      
The diameter of polysulfone nanofibers prepared by the gas jet/electrostatic spinning was in the range 50-500 nm.
      
It is concluded that the gas-jet/electrospinning is a better method than the conventional electrospinning, in that it makes the nanofibers finer and more uniform and exhibits higher efficiency in the process of electrospinning.
      
Preparation of anhydrous magnesium chloride in a gas-solid reaction with ammonium carnallite
      
The volatile oil, the fraction of petroleum ether: EtOAc = 20:1 (V/V) on Si gel chromatography, was also quantitatively analyzed by gas chromatography mass spectrometry (GC-MS).
      
Surface modification of CaCO3 filler and its characterization using inverse gas chromatography (IGC)
      
Inverse gas chromatography (IGC) was used to investigate the surface free energy of CaCO3 after surface modification and to optimize the monolayer content of coupling agents.
