The reactivity of organic molecules in hot water is a field of chemistry developing from studies aimed at understanding how organic matter (kerogen) forms in natural environments and then breaks down into energy source materials. In natural systems where kerogens are depolymerized, water is ubiquitous and hot and usually contains salt and minerals. Reactions such as cleavages and hydrolyses in ...

Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a loc...

One of the important research topics is potential impact changes in oil supply and demand on current future price movements or financial market instruments. Especially developing countries such as Russia, which an natural gas exporter, sanctions exports affect country a macroscale businesses microscale. In this context, aim aforementioned study to examine causality relationship between Brent pr...

In the field of host-guest chemistry, some of the most widely used hosts are probably cyclodextrins (CDs). As CDs are able to increase the water solubility of numerous drugs by inclusion into their hydrophobic cavity, they have been widespread used to develop numerous pharmaceutical formulations. Nevertheless, CDs are also able to interact with endogenous substances that originate from an organ...

Data on the chemistry of biologically active components of petroleum, synthetic fuel oils, certain metal elements and pesticides provide valuable generic information needed for predicting the long-term fate of buried waste constituents and their likelihood of entering food chains. Components of such complex mixtures partition between solid and solution phases, influencing their mobility, volati...

Marilyn Monroe knew that "diamonds are a girl's best friend" but, in the meantime, many chemists have realized that they are also extremely attractive objects in contemporary chemistry. The chemist's diamonds are usually quite small (herein: nanometer-sized "diamondoids") and as a result of their unique structure are unusual chemical building blocks. Since lower diamondoids (up to triamantane) ...

OBJECTIVE Although petroleum products are useful chemical compounds which form an integral part of our modern technology, they have been reported to cause deleterious effect on health following their inhalation. Petroleum hydrocarbons-dependent health hazards and their mechanisms have been associated with the routes of administration. This study, therefore, aimed at the isolation and chemical c...

Hydrocarhon free radicals play a very important role in many thermalchemistry processes. including combustion. petroleum and coal coking, coal liquefaction and pyrolysis. oil shale retorting, thermal stability of fuels as well as free rddiciij polymerization. To obtain heats of formation (AH",) of the radicals is very essential for the fundamental understanding of thermal chemistry and mechanis...
