Global Chemical Kinetics of Fossil Fuels: How to Model Maturation and PyrolysisThis book covers the origin and chemical structure of sedimentary organic matter, how that structure relates to appropriate chemical reaction models, how to obtain reaction data uncontaminated by heat and mass transfer, and...
Basically, the conversion of these “recalcitrant” resource relies on the use thermochemical or enzymatic processes to break down the complex structure of the lignocellulosic material into its main constituents: cellulose, hemicellulose, and lignin. After a single multistage separation procedure, each com...
Materials scientists lay stress on understanding how the history of a material influences its structure, and thus its properties and performance. All engineered products from airplanes to musical instruments, alternative energy sources related to ecologically-friendly manufacturing processes, medical devices ...
Lithium-ion battery structure that self-heats at low temperatures Here we report a lithium-ion all-climate battery that very efficiently heats itself up in extremely cold environments by diverting current through a strip of metal foil to generate heat of resistance and then reverts to normal high...
A drug or single pollutant chemical is a well-defined molecular-scale entity characterized by a single chemical structure, or is at worst a quantifiable mixture of defined chemical compounds. From:Comprehensive Toxicology,2010 Also in subject area: ...
The bioplastic was malleable, but is more expensive to produce than are plastics made from fossil fuels. Felicity Nelson Article | 12 March 2025 Structure and mechanism of the plastid/parasite ATP/ADP translocator ATP/ADP translocators in obligate intracellular parasites and plastids facilitate ene...
Fossil fuels used as feedstock and process gas for chemical processes require technological innovation, such as the use of recycled materials, captured carbon, and alternative reduction agents. The combustion of fossil fuels for steam, electricity, and heat generation can be electrified, but some ...
Petroleum is a useful source of chemical energy because, in the presence of oxygen, it requires less energy to break the bonds in the petroleum and it releases excess energy when new bonds reform. The burning (combustion) of fossil fuels is considered an exothermic reaction. The major by...
It may also call for less suburban development and less reliance of fossil fuels. Conversely, it could also lead to even less research risk-taking, which could translate into less scientific advancement [99]. Another aspect of a disaster is how well it can be addressed within the normal ...
ordered by the monomeric units used and the structure of the biopolymer framed, are polynucleotides (RNA and DNA), polymers, which are lengthy polymers composed of at least 13 nucleotide monomers, polypeptides, which are concise polymers of amino acids; and polysaccharides, which are typically supp...
