It also includes many classes of organic compounds spanning a large molecular weight range and including carbohydrates, aromatics, starches, nitrogen-containing compounds, and fatty acids1. The physical, biological, and chemical properties of soils could change significantly as a result of human ...
These chemical features are distinct and reflect reactions involving the orthopyroxenes. Compared to the CMPs, the OMPs, which are composed of a complex assemblage of minerals, display lowe 展开 关键词: Experimental/ Earth mantle garnets geochemistry mass spectroscopic chemical analysis minerals organic...
1b, displays all the expected features of a narrow-gap Mott Insulator with a Hubbard energy (U) of the order of 0.55 eV27. The low-bias resistivities r(T) measured with a standard four-probe technique for the series of compounds GaTa4Se8 À xTex exhibit a semiconducting-like ...

of the different structures are determined from Matlab fitting of XSEM-images and are tabulated in Table1. The samples are subjected to dry surface modification steps to render the surface superhydrophobic. After UV/O3-treatment for 15 minutes to remove any organic contamination, the pillars are...
long-chain oil molecules, which produces hydrogen and light hydrocarbon compounds, in particular. Additionally, the decomposition of cellulose produces carbon monoxide and carbon dioxide, which can occur in dissolved and/or undissolved form depending on the amount of the produced gasses. Thus, water ...
The strongest increase of TOC and TN content (100% on average initial content) for bag types, zones, and streams was observed in the first two weeks of the experiment. These results confirm the importance of chemical compounds for microbiological processes (biofilms) in different ecosystem biotope...
For example, processes which obtain fuels from the cellulose or hemicellulose component of plants have been developed. Renewable vegetable raw materials comprise, as well as cellulose and hemicellulose, also lignin, lignin being the second most common organic substance on earth after cellulose. ...
In the current work, filtration using a tubular ceramic membrane (伪-Al 2O 3 or TiO 2) was combined with ozonation to remove organic compounds present in a secondary effluent to enhance key quality features of the water (colour and total organic carbon, TOC) for its potential reuse. 'Bare...
