Aerosol formation during parforce: ternary nucleation of h2so4, nh3, and h2o
(Wiley-Blackwell, 2002-01-01)A new version of a ternary nucleation (sulphuric acid-ammonia-water) model based on classical nucleation theory, but with an improved ability to predict nucleation rates over a larger temperature range (258-303 K) compared ... -
Arctic sea ice melt leads to atmospheric new particle formation
(Springer Nature, 2017-06-12)Atmospheric new particle formation (NPF) and growth significantly influences climate by supplying new seeds for cloud condensation and brightness. Currently, there is a lack of understanding of whether and how marine biota ... -
Bioelectrochemical Haber-Bosch process: An ammonia-producing H-2/N-2 fuel cell
(Wiley, 2017-02-03)Nitrogenases are the only enzymes known to reduce molecular nitrogen (N-2) to ammonia (NH3). By using methyl viologen (N, N'-dimethyl-4,4'-bipyridinium) to shuttle electrons to nitrogenase, N-2 reduction to NH3 can be ... -

Determination of alkylamines in atmospheric aerosol particles: a comparison of gas chromatography–mass spectrometry and ion chromatography approaches
(Copernicus GmbH, 2014-07-04)In recent years low molecular weight alkylamines have been recognized to play an important role in particle formation and growth in the lower atmosphere. However, major uncertainties are associated with their atmospheric ... -
Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ... -
Renal and hepatic nitrogen metabolism during nh4cl ingestion in protein-deprived rats
(Wiley-Blackwell, 1998-06-01)Three groups of rats were given either a standard protein diet, a protein-free diet, or a protein-free diet with the inclusion of 0.28 M NH4Cl in their drinking water, for 10 days. Body, liver and kidney masses were decreased ... -
Sodium hydroxide catalyzed monodispersed high surface area silica nanoparticles
(IOP Publishing, 2016-07-29)Understanding of the synthesis kinetics and our ability to modulate medium conditions allowed us to generate nanoparticles via an ultra-fast process. The synthesis medium is kept quite simple with tetraethyl orthosilicate ... -
The effects of grain treatment, grain feed level and grass silage feed value on the performance of and meat quality from, finishing beef cattle
(Cambridge University Press (CUP), 2007-12-18)A completely randomised design study involving 132 continental crossbred beef steers was undertaken to evaluate the effects of method of grain treatment and feed level, and grass silage feed value on animal performance, ...
