Ammonia toxicity and cerebral oxidative metabolism
American Journal of Physiology-Legacy Content, 1961Effects of NH4Cl on oxidative metabolism of cat cerebral cortex slices and mitochondria incubated in vitro were studied. In slices, addition of 10 mm NH4Cl to the incubation medium resulted in significant (16%) reduction of O2 uptake, doubling of lactic acid production and marked increase of glucose utilization compared to control slices. Mitochondria

(Invited) Electrocatalytic Ammonia Oxidation
ECS Meeting Abstracts, 2020Much of the global effort toward producing solar fuels has involved splitting water to obtain molecular hydrogen. Unfortunately, hydrogen gas has a relatively low energy-per-volume, and extreme cryogenic temperature and pressure is needed to bring hydrogen to a condensed state.

Catalytic Oxidation of Ammonia
Russian Chemical Reviews, 1976Data on the catalytic properties of various substances (metals, their alloys, simple and complex oxides, and zeolites containing metal cations) in the oxidation of ammonia are described systematically and reviewed. The kinetics and mechanism of the reaction are discussed and the factors determining the activity and selectivity of the catalysts are ...

Diversity of ammonia monooxygenase operon in autotrophic ammonia-oxidizing bacteria
Archives of Microbiology, 2001Autotrophic ammonia-oxidizing bacteria use the essential enzyme ammonia monooxygenase (AMO) to transform ammonia to hydroxylamine. The amo operon consists of at least three genes, amoC, amoA, and amoB; amoA encodes the subunit containing the putative enzyme active site.

Genetic Transformation of Ammonia-Oxidizing Bacteria
2011The study of traits of ammonia-oxidizing bacteria (AOB) by genetic transformation is an approach that is facilitated by the availability of AOB genome sequences. To transform an AOB, a vector construct is introduced into the cells by electroporation or conjugation to effect the inactivation, complementation, or expression of a selected gene.

Nature, 1919
IT is regretted that there is an error in the second equation of those suggested in NATURE of April 24 which makes the scheme there given impossible. The writer still considers that nitrohydroxylamic acid is a possible intermediate product, as will be explained below, but it cannot be derived as previously given.
