2010/3/5
We present a novel analytical approach to measure the chemical composition of organic aerosol. The new instrument combines proton-transfer-reaction mass-spectrometry (PTR-MS) with a collection-thermal...
Equilibrium desorption isotherms of water, ethanol, ethyl acetate, and toluene on a sodium smectite clay
Clay Dynamic vapour sorption Ethanol Ethyl acetate Knudsen thermogravimetry Smectite Sorption isotherm Toluene Water
font style='font-size:12px;'>
2011/11/10
Abstract Desorption isotherms for water, ethanol, ethyl acetate and toluene from a sodium smectite clay have been determined by both dynamic vapor sorption (DVS) measurements and Knudsen thermogravim...
Desorption of benzoic and stearic acid adsorbed upon montmorillonites: a thermogravimetric study
Thermogravimetric analysis Differential thermogravimetric analysis Montmorillonites Desorption Benzoic acid Stearic acid
font style='font-size:12px;'>
2011/11/11
The desorption of benzoic acid and stearic acid from sodium and calcium montmorillonites has been studied using thermogravimetric and differential thermogravimetric analysis. Desorption of benzoic aci...
Direct Ionization Desorption of Fullerene by Intense Femtosecond Laser Fields
C60 Solid Femtosecond Ionization
font style='font-size:12px;'>
2009/6/1
We investigated the direct ionization and desorption of solid C60 by the irradiation of femtosecond nonresonant (neutral and cationic states) pulses at 1.4 µm. We concluded that ion desorption i...
No detectable aerobic methane efflux from plant material,nor from adsorption/desorption processes
