10 The influence of structure, phase composition, system dispersity and particle morphology of Fe2O3and In2O3-based thin film layers on the electrical parameters of the corresponding gas sensors was studied in this paper. High selectivity and sensitivity of heterostructural -Fe2O3/In2O3 thin film sensors in the detection of alcohols has been here established. As it was found, the above mentione...

Multilevel observations of formaldehyde (H2CO) and methanol (CH3OH) toward the nearby spiral galaxies NGC 253, Maffei 2, IC342, M82 and NGC6946 are presented. H2CO was detected in all galaxies (tentatively in NGC6946). CH3OH was detected in all objects with the notable exception of M82. H2CO line intensity ratios point out differences in gas density both between galaxies and within the central ...

A series of L-di-2-thenoyltartaric acid lanthanide coordination polymers, namely, {[La2L3(CH3OH)6(H2O)]·CH3OH·H2O}n (1), {[Ln2L3(CH3OH)x(H2O)6−x]·aCH3OH·bH2O}n, [Ln = Eu (2), x = 2, a = 0.5, b = 0.25; Ln = Gd (3), x = 3, a = 1, b = 0; Ln = Tb (4), x = 2, a = 1, b = 0], {[(Eu0.037Tb0.963)2L3(CH3OH)2(H2O)4]·CH3OH·2.75H2O}n (5), {[(Eu0.051Tb0.406La0.543)2L3(CH3OH)2(H2O)4]·0.5CH3OH·2H2O}n (6), and ...

We present 1 resolution CARMA observations of the 3mm continuum and 95GHz CH3OH masers toward 14 candidate high mass protostellar objects (HMPOs). Dust continuum emission is detected toward seven HMPOs, and CH3OH masers toward 5 sources. The 3mm continuum sources have diameters < 2× 10AU, masses between 21 and 1200M⊙, and volume densities > 10 8 cm. Most of the 3mm continuum sources are spatial...

The coadsorption of methanol (CH3OH) and water (D2O) on the MgO~100!/Mo~100! surface at 100 K has been studied by metastable impact electron spectroscopy ~MIES!, ultraviolet photoelectron spectroscopy @UPS ~HeI!#, and by thermal programmed desorption ~TPD!. Methanol wets the MgO surface and adsorbs nondissociatively within the first monolayer with the hydroxyl group oriented toward the substrat...

Complex intra-molecular interactions and the hydrogen-bonding network in H2O-volatile mixtures play critical roles in many dynamics processes in physical chemistry, biology, and Earth and planetary sciences. We used high pressure Raman spectroscopy to study the pressure evolution of vibrational frequencies and bonding behavior in H2O-CH3OH mixtures. We found that the presence of low CH3OH conte...

Photochemical processes for CH3X (X = Cl, Br, I) adsorbed on top of thin films of D2O or CH3OH on a Cu(110) substrate is studied by time-of-flight mass spectrometry for a range of UV wavelengths (351-193 nm). Photodissociation via dissociative electron attachment by photoelectrons and by neutral photodissociation is identified and quantified based on the observed dynamics of the desorbing CH3 f...

We report the first detection of triply-deuterated methanol, with 12 observed transitions, towards the low-mass protostar IRAS 16293−2422, as well as multifrequency observations of CH3OH, used to derive the column density of the main isotopomer CH3OH. The derived fractionation ratio [CD3OH]/[CH3OH] averaged on a 10′′ beam is 1.4%. Together with previous CH2DOH and CHD2OH observations, the prese...
