Chirality is a widespread phenomenon in nature, ranging from helical DNA’s and RNA’s enantiomeric components to the shape of galaxies65. Chiral organic compounds are an important part of the pharmaceutical industry. In molecular chemistry, chiral molecules (called enantiomers or optical isomers) are...
Chiral organic compounds are an important part of the pharmaceutical industry. In molecular chemistry, chiral molecules (called enantiomers or optical isomers) are those which have the same chemical composition but constitute mirror images of each other and cannot be superimposed by any sym- metry ...
(5) production of huge amount of degradation volatile compounds, and (6) severe environmental degradations. Similarly, the exhaust emissions of amines can alsodegrade into the nitramines andnitrosamines, having enough potential to destroy the human health and harm the environment. The “chilling ...
vulgaris has been generally regarded to show a safe status as an alternative protein-rich biomass, nutraceutical, and source of bio-compounds. This organism can be fermented like yeasts on simple sugars as a carbon source [134], [135]. Chlamydomonas is another genus of green algae, known for...
In the carbothermic process, the final metal producing step is obtained by a reaction between the intermediate compounds SiO and SiC, but an alternative silicon forming reaction seems elusive when using only hydrogen as a reduction agent as reduction of SiO to Si by H2 is not favored by ...
Of all these gases, carbon dioxide is the most important, both for its role in the greenhouse effect and for its role in the human economy. It has been estimated that, at the beginning of the industrial age in the mid-18th century, carbon dioxide concentrations in the atmosphere were rough...
bondedcompounds containing carbon. Thisisotopeis also useful as a label incompoundsthat are to be analyzed bymass spectrometry, another device that is used extensively to identifyatomsandmolecules. Of the unstable nuclides, only carbon-14 is of sufficiently longhalf-lifeto be important. It is ...
As can be seen in Table 1, most of the studies did not take all the important aspects into consideration. The major contribution of this study to the literature is that the proposed integrated model deals with the inventory management for both sides of the SC, regarding the two carbon emissi...
Pixels that fall within the training area were taken as the training pixels for a particular class. In order to select a good training area for a class, the important properties (e.g., uniformity) and how well they represent the same class throughout the whole image were taken into ...
1) All aromatic compounds, even the most simple, are relatively richer in carbon than the corresponding compounds in the class of fatty bodies.2) Among the aromatic compounds, as well as among the fatty bodies, a large number of homologous substances exist.3) The most simple aromatic ...
