Sevoflurane Breakdown Produces Flammable Concentrations of Hydrogen » Background. Fires, explosions, and extreme heat production may occur when sevoflurane reacts with desiccated barium hydroxide lime. The identity of the flammable gas has not previously been published, although carbon monoxide, methanol, formaldehyde, and methyl formate have been identified in low quantities.Methods. The authors reacted sevoflurane with excess desiccated barium hydroxide lime or soda lime at 55 degrees, 100 degrees, 200 degrees, 300 degrees, and 400 degrees C. Formaldehyde, methanol, sodium formate, and hexafluoroisopropanol were reacted with barium hydroxide lime at 300 degrees or 400 degrees C. The authors measured hydrogen production by gas chromatography with a thermal conductivity detector and calculated the molar yield of hydrogen produced.Results. Up to 3 moles of hydrogen were produced per mole of sevoflurane degraded. Each mole of formaldehyde produced up to 2 moles of hydrogen at 400 degrees C. Formate and hexafluoroisopropanol produced up to 1 mole of hydrogen each at 400 degrees C. Dx.doi.org

Extraction of Green Tea Phenolics Using Water Bubbled with Gases » Abstract Water was bubbled with gases including nitrogen (N2), oxygen (O2), hydrogen (H2), carbon dioxide (CO2), and air for 10 min and phenolics from green tea leaves were extracted using the prepa… Ift.onlinelibrary.wiley.com

Hydrogen sulfide exposure in an adult male » Hydrogen sulfide (H[2] S) is responsible for many incidents of occupational toxic exposure, especially in the petroleum industry. The clinical effects of H[2] S depend on its concentration and the duration of exposure. H[2] S is immediately fatal when… Ncbi.nlm.nih.gov

Anammox--growth physiology, cell biology, and metabolism - PubMed » Anaerobic ammonium-oxidizing (anammox) bacteria are the last major addition to the nitrogen-cycle (N-cycle). Because of the presumed inert nature of ammonium under anoxic conditions, the organisms were deemed to be nonexistent until about 15 years ago. They, however, appear to be present in virtuall … Pubmed.ncbi.nlm.nih.gov

Accurate and Compatible Force Fields for Molecular Oxygen, Nitrogen, and Hydrogen to Simulate Gases, Electrolytes, and Heterogeneous Interfaces » Gas molecules and interfaces with liquids and solids play a critical role in living organisms, sorption, catalysis, and the environment. Monitoring adsorption and heterogeneous interfaces remains difficult in experiments, and earlier models for molecular simulations lead to errors over 100% in fundamental molecular properties. We introduce conceptually new force field parameters for molecular oxygen, nitrogen, and hydrogen that reduce deviations to <5%. We employ a combination of a harmonic bond stretching potential and Lennard-Jones parameters with 12-6 and 9-6 options, leading to computed bond lengths, Raman peaks, liquid densities, vaporization enthalpies, and free energies of hydration in impressive agreement with experiments. Reliable free energies of hydration were obtained upon validation of density and vaporization energy without significant further parameter adjustments. We illustrate applications to O2 adsorption on Pt electrocatalysts and N2 adsorption in zeolites, showing <5% deviation in adsorpti Pubs.acs.org
