“…Once NDMA and DMA are fully mineralized, the mineral sorbents can be readily reused, as the microwave irradiation barely affects their microwave-transparent framework. Together, the promising laboratory results indicate that microporous mineral sorption coupled with microwave-induced (2008); (2) Oxidation of DMA radical by oxygen reported in Li et al (2015); (3) Thermal decomposition pathway reported in Pratt and Purnell (1961); (4) Pyrolysis reaction reported in Hill et al (1996); (5) Pyrolysis reaction reported in Lovas et al (1975) and Mulcahy et al (2000); (6) Thermal decomposition pathway reported in Pratt and Purnell (1961); (7) Radical reaction reported in Hill et al (1996); and (8) Unimolecular decomposition of DMA reported in Li et al (2015). It should be noted that many more complicated reactions are probably involved due to the existence of multiple radicals and reactive species under the pyrolytic conditions, and these simple reactions are shown to illustrate that degradation of NDMA and DMA could yield the major products detected in this study.…”

“…An alternative route would be the breaking of a single C-H bond, resulting in N-methylenemethylamine (CH 2 =N-CH 3 ) [51,52]. Both HCN and N-methylenemethylamine have been reported as decomposition products of dimethylamine over Si(100) [38].…”

“…With very few exceptions [28][29][30], previous studies of amine surface chemistry have considered adsorption only at clean metal [28,[31][32][33][34][35] or silicon surfaces [36][37][38] and utilised in the main temperature programmed desorption (TPD) and vibrational spectroscopy (RAIRS and HREELS). We have, on the contrary, studied reactions with other adsorbed species, particularly oxygen [11,13,[39][40][41].…”

Molecularly Resolved Studies of the Reaction of Pyridine and Dimethylamine with Oxygen at a Cu(110) Surface

et al. 2005

Pyridine and dimethylamine have been studied at clean and oxidised Cu(110) surfaces as model systems for the interaction of amines with heterogeneous catalysts using scanning tunnelling microscopy and X-ray photoelectron spectroscopy. Both molecules interact strongly with sub monolayer concentrations of chemisorbed oxygen causing a change from the well known p(2 · 1)O(a) islands to a (3 · 1) structure. XPS shows a 1:1 correspondence between the concentration of surface oxygen and that of chemisorbed pyridine but the stoichiometry of the dimethylamine/oxygen system could not be directly measured because of a slow reaction which results in the desorption of oxygen as water and the formation of a chemisorbed amide. The amide also decomposes at room temperature and desorbs leaving a clean surface. However, the 2:1 stoichiometry of the dimethylamine/oxygen reaction suggests a 1:1 dimethylamine:oxygen ratio in the (3 · 1) structure. The results of the study are interpreted in terms of an amineoxygen complex, which may provide a general model for the interaction of amines with oxygen at metal surfaces.

“…It has been reported [20] that the produced dimethylamine can be readily adsorbed on Si substrates and can be further decomposed to dehydrogenated imine products. The liberating hydrogen favors reduction of Co(acac) 2 , but the hydrogen bonding involved in thermally decomposed imine Full Paper products stabilizes sorption of organic compounds in the produced film, thus increasing C contamination.…”

Cobalt thin films are deposited by metal-organic (MO)CVD, under various experimental conditions, on Si and SiO 2 substrates. The precursors used are cobalt nitrosyl tricarbonyl, Co(CO) 3 NO, cobalt acetylacetonate, Co(acac) 2 , and cobalt carbonyl, Co 2 (CO) 8 . Emphasis is given to the delivery method of each precursor, especially to a new technique of aerosol delivery. The films are thoroughly examined in terms of microstructure and surface morphology in order to establish relevance to magnetic properties. It is found that Co films deposited from Co 2 (CO) 8 dissolved in dichloromethane are characterized by a high degree of planarity and purity, while exhibiting a non-hysteretic giant magnetoresistance (GMR) behavior in the presence of an externally applied magnetic field normal to their surface.
