The most important types of organic matter in geosphere have already been mentioned. These are the fulvic and humic acids, humin, kerogen (in coal, oil shales, source rocks or scattered in the sediments), bitumen, oil, gas and graphite. All these forms are genetically related and are part of the carbon cycle in nature, or carbon cycle in the geosphere (larger circle in Fig. 1.4). Central place ...

Two organic gas speciation profiles (OG2403 and OG2404) for compressed natural gas (CNG) transit buses equipped with three-way catalysts (TWC) were developed in this work to complement the current CARB organic gas speciation profile database. The profiles were created based on chassis dynamometer test data of two transit buses equipped with TWCs running on CNG. Profile OG2403 was made for Stead...

The soil bacterium Bacillus subtilis can use sugars or organic acids as sources of carbon and energy. These nutrients are metabolized by glycolysis, the pentose phosphate pathway, and the Krebs citric acid cycle. While the response of B. subtilis to the availability of sugars is well understood, much less is known about the changes in metabolism if organic acids feeding into the Krebs cycle are...

My half-century journey started from synthetic organic chemistry. During the first stage of my journey, my interest in stereochemistry was initiated through the investigation on the participation of steric effects in reactive intermediates, cylophanes, strained heterocycles, and organic compounds for photography. In chemoinformatics as the next stage of the journey, I proposed the concept of im...

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

The bacteria and their phages are the most abundant constituents of the aquatic environment, and so represent an ideal model for studying carbon regulation in an aquatic system. The microbe-mediated interconversion of bioavailable organic carbon (OC) into dissolved organic carbon (DOC) by the microbial carbon pump (MCP) has been suggested to have the potential to revolutionize our view of carbo...

organic acid occur as physiologic intermediates in variety of intracellular metabolic pathways, such as catabolism of aminoacid, mitochondrial β oxidation of fatty acids, tricarboxilic acid cycle, and cholestrol and fatty acid biosynthesis. the classical organic aciduria represent the pursuit of abnormalities of aminoacid degradation beyond deamination their diagnostic hallmark is an accumulati...

A new hybrid approach consists to use the advantages of both systems namely the high geometric aspects of the electrodes of the ultracapacitor and the high dielectric strength of polymer materials used in dielectric capacitors. The surface roughness of the electrodes of the ultracapacitor is manufactured with nano-porous materials; activated carbon and carbon nanotubes (CNTs). Many compositions...
