Nuclear and Other Instrumental Analytical Techniques in Investigation of Cultural Heritage: Complementarity and Competitivity
(Srpsko hemijsko društvo, 2007)
Nuclear analytical techniques (NATs), including INAA. XRF, PIXE, stable and radioisotopes, a, B, y-spectrometry, AMS, etc. have been applied to a wide range of cultural heritage materials with varying success. NATs featuring ...
Low concentration volatile organic pollutants removal in combined adsorber-desorber-catalytic reactor system / Integrisani sistem adsorber-desorber-katalitički reaktor za uklanjanje malih koncentracija organskih zagađujućih materija
(Association of Chemical Engineers of Serbia, 2008)
The removal of volatile organic compounds (VOCs) from numerous emission sources is of crucial importance due to more rigorous demands on air quality. Different technologies can be used to treat the VOCs from effluent gases: ...
Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
