The heat capacity of 99.8% pure hydrogen fluoride has been measured between 15 and 300°K. No transitions were found, in the solid, as is the case in the other hydrogen halides; this is probably due to the existence of hydrogen bonding in hydrogen fluoride. The heat of fusion at the mel...

And engine power is influenced by both hydrogen fraction and heat value in low heat value gas-hydrogen blends combining. Hydrogen significant extends the lean burn limit of combustion of low heat value gas. 展开 关键词: Emission Hydrogen Low Heat Value Gas ...
The oil is derived from an oil selected from the group consisting of fish, animal, vegetable, synthetic and genetically-modified plant oils. The iodine value is described to be below 110. A process of preparing a hydrogenated oil composition is described wherein the hydrogenating comprises ...
Hydrogen bonds in adsorption One of the common reasons for molecular association in aqueous solutions and other liquids is the formation of hydrogen bonds between the pertinent polar parts of the molecules, e.g. between the hydroxyl groups. This association also occurs during adsorption on adsorbents...
The resulting P-values were corrected by the approach of Benjamini and Hochberg to limit the false discovery rate (FDR) (Benjamini and Hochberg, 1995). DEGs were filtrated with a P-value < 0.05 by DESeq2. The analysis of subclusters and hierarchical heat maps was respectively based on the...
摘要: PROBLEM TO BE SOLVED: To prevent the generation of hydrogen which is a critical defect of a chemically heat-generating agent comprising powder aluminum and powder calcium oxide generating heat by reacting with water, and to obtain a required heating value....
Therefore, it is considered that in the ATZ degradation procedure, a hydroxyl group replaced a hydrogen atom to generate 2-chloro-4-hydroxy-ethylene-6-isopropyl ATZ (2-Chloro-4-hydroxyethylamino-6-isopropylatrazine, CHEIA). m/z232 has a molecular mass 18 more than m/z214, so m/z128 is...
Bentz (2007) qualitatively compares the heat capacity of this porewater phase with that of water ice, noting the unusually high specific heat capacity of bulk liquid water can be attributed to energy consumed in bending and breaking of mobile hydrogen bonds. In molecular-dynamics simulations, Qomi...
