The tungsten piperidylhydrazido complex Cl4 CH3CN W N-pip 1 was used for film growth of tungsten carbonitride WNxCy by metal-organic chemical vapor deposition CVD in the absence and presence of ammonia NH3 in H2 carrier. The microstructure of films deposited with NH3 was x-ray amorphous between 300 and 450 °C. The chemical composition of films deposited with NH3 exhibited increased N levels and...

In the title complex, [Co(CO3)(NH3)4]ClO4, both the cation and anion lie on a mirror plane. The Co(III) ion is coordinated by two NH3 ligands and a chelating carbonato ligand in the equatorial sites and by two NH3 groups in the axial sites, forming a distorted octa-hedral geometry. In the crystal, N-H⋯O hydrogen bonds connect the anions and cations, forming a three-dimensional network.

We investigated whether [SiF4(NH3)2] can act as a fluoride-ion acceptor in its reactions with the fluorides AF (A = Li-Cs, Tl, NH4) anhydrous liquid ammonia (NH3). While LiF and NaF did not react, we obtained compounds K[SiF5(NH3)], Rb[SiF5(NH3)], Cs[SiF5(NH3)], well [NH4(NH3)2]2[SiF6] [Tl2(NH3)6][SiF6]·2NH3, from other starting materials characterized them by either single-crystal or powder X-...

The tolerance of 26 Bacillus species isolated from alkaline fermented foods, five other bacilli and nine non spore-forming bacteria to alkaline pH and ammonia was determined. All grew at pH 7, 8 and 9 in the presence of 930 mmol l-1 NH4 + at pH 7.0, and in the presence of NH3 concentrations up to 5 mmol l-1 at pH 7.0 and 8.0. At higher NH3 concentrations, growth of some of the bacteria was inhi...

We present measurements of ammonia (NH3) over a deciduous forest in southern Indiana collected during four field campaigns; two in the spring during the transition to leaf-out and two during the winter. Above canopy NH3 concentrations measured continuously using two Wet Effluent Diffusion Denuders indicate mean concentrations of 0.6– 1.2mgm 3 during the spring and 0.3mgm 3 during the winter. Me...

Carbon nanotubes (CNT) are extremely sensitive to environmental gases. However, detection of mixture gas is still a challenge. Here, we report that 10 ppm of carbon monoxide (CO) and ammonia (NH3) can be electrically detected using a carboxylic acid-functionalized single-walled carbon nanotubes (C-SWCNT). CO and NH3 gases were mixed carefully with the same concentrations of 10 ppm. Our sensor s...

This chapter considers the emissions of ammonia (NH3), nitrous oxide (N2O), other oxides of nitrogen (NOx), carbon dioxide (CO2), methane (CH4), and non-methane volatile organic compounds (NMVOCs) from agricultural soils to which nitrogen (N)-containing fertilizers are applied. For NH3, emissions following application of animal manures to land are considered in SNAP code 100900, Manure Manageme...

Additions of methionine sulfoximine (MSX), an inhibitor of glutamine synthetase (GS), result in an increase in NH13 in seedling leaves of Cs (wheat I Triticum aestiwn cv. Kolibril and barley [Hordeum vulgare var Perthi) and C4 (corn IZea mays W6A x W182E1 and sorghum [Sorghun Vulgare var MK3001) plants. NH13 accumulation is higher in C3 (about 17.8 micromoles per gram fresh weight per hour) tha...

We report the detection of the (1,1) and (2,2) metastable lines of ammonia (NH3) in the molecular cloud associated with the Wolf–Rayet (WR) nebula NGC2359. Besides the CO and H2, this is the first molecule detected in the environs of a WR star. Width (∆V1/2 = 3km s ) and radial velocity (VLSR ∼ 54 km s ) indicate that the NH3 lines arises from the molecular cloud which is interacting with the W...

We present results of a survey of CCS, HC3N, and HC5N toward 40 dark cloud cores to search for ”Carbon-Chain–Producing Regions(CCPRs)”, where carbonchain molecules are extremely abundant relative to NH3, as in L1495B, L1521B, L1521E, and the cyanopolyyne peak of TMC-1. We have mainly observed toward cores where the NH3 lines are weak, not detected, or not observed in previous surveys, and the C...
