Abstract Chemical Abstracts

2016-3-28 · Mixtures of acetone with dimethyl sulfoxide or 1-methyl-2-pyrrolidone led to submicron particles with a spherical morphology. The main parameters that could affect the nano- or micro-precipitation were studied using mixtures of acetone and dimethyl sulfoxide rather than 1-methyl-2-pyrrolidone due to the low toxicity of DMSO.

Experimental and Modeling Investigation of the Effect …

2019-3-10 · The autoignition and oxidation behavior of CH4/H2S mixtures has been studied experimentally in a rapid compression machine (RCM) and a high-pressure flow reactor. The RCM measurements show that the addition of 1% H2S to methane reduces the autoignition delay time by a factor of 2 at pressures ranging from 30 to 80 bar and temperatures from 930 to 1050 K.

Helium - Wikipedia

2019-4-23 · Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. Helium at low temperatures is used in cryogenics, and in certain cryogenics appliions.
