Objective:To analyse the chemical components of processed Cortex Cinnamomi from different Pharmacy.Methods:The chemical components of essential oils of the samples were determined by GC-MS.Results:Contents of essential oils of the samples are between 0.3-1.5 mL·g-1.45 chemical components were identifi...
The Chemical Composition of the Interior Shells of the Earth The suggestion is made that the core and lower mantle of the Earth are chemically analogous to the two principal components of highly reduced enstatite cho... JM Herndon - 《Proceedings of the Royal Society A Mathematical Physical & ...
Surprisingly, the chemical profile of the lesion tissue was clearly different from those of the other two zones and healthy leaves from a non-infected plant (CON) (Fig. 1b). The main components identified in healthy leaves and lesion tissue were designated compounds 1–4 and 1a–4a, ...
The response of the MnO2/TiO2 sensors towards 100 ppm triethylamine at 200 °C is 6.8, which is superior to that of both components alone. It reveals that compositing MnO2 with TiO2 leads to a higher Mn4+/Mn3+ ratio and in turn more adsorbed oxygen on the surface, which contributes to...
The 3D structure generator builds linear components from scratch following geometrical rules based on the hybridization of the atoms. Single-conformer ring templates are used for ring systems. The template matching algorithm iterates through the templates from largest to smallest searching for matches. ...
Therefore, yearly differences in food availability could potentially affect the production and concentration of different chemical components in the two species. Outside of the reproductive season, iguanas seem to scatter along the slopes of the volcano, where different environmental conditions and trophic...
Chemical companies are investing in high-tech, clean energy—and other high-growth areas. So far in 2024, data from the Federal Reserve Board indicates that semiconductors and electronic components, oil and gas extraction, architectural and structural metals, and plastics and rubber industries have ...
Independent claims are included for: (1) a process for the production of compounds (I) by production of oligomers or polymers by organometallic reactions; (2) electronic components containing compounds (I) as semi-conductors.シュテファン キルヒマイヤー...
exists between conventional logging response and element component for the complex metamorphic rock.On the condition of gaining element analysis data,by using well logging data,evaluation models of chemical components in strata has been set up.It can provide more direct data for lithology and ore ...
Biomass is a heterogeneous mixture of compounds that include cellulose, hemicellulose, starch, chitin, and lignin, itself a sophisticated assembly of complex compounds, such as coniferal alcohols. Depending on the source of biomass, other components can also be present, such as fats, waxes, protein...
