A study of the fine rnicrostructure of boronated pyrolytic graphite was made utilizing optical and X-ray diffraction techniques. The influence of boron content on the laminar structure, the lattice parameter, the lattice strain, the particle size, and the flexural strength of pyrolytic graphite were studied. Significant changes in the behavior of all investigated parameters were observed in the...
Catalytic microwave pyrolysis of biomass using activated carbon (AC) was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. Bio-oils with high concentrations of phenol (38.9%) and phenolics (66.9%) were obtained. These levels were higher than those obtained by pyrolysis without AC addition and were closely related to the decomposition of lignin....
Tabernaemontana divaricata a common garden plant in tropical countries has been used as a traditional medicine. However, no recent review articles of T. divaricata, particularly discussing its pharmacological properties, are available. This review presents the ethnobotany and ethnopharmacology of T. divaricata as well as its potential therapeutic benefits especially of the alkaloidal and non-al...
It has been found that multiwalled carbon nanotubes (CS-CNT) can be produced in mass level, simply by pyrolysing mustard oil which was then derivatized with carboxylic acid (CS-CNT (acid)) and ammonia (CS-CNT (base)). A low cost electrode was fabricated on Teflon substrate with three silver wires which was coated with different types of carbon nanotube. A comparative study of electrochemical be...
The shock-induced transition from graphite to diamond has been of great scientific and technological interest since the discovery of microscopic diamonds in remnants of explosively driven graphite. Furthermore, shock synthesis of diamond and lonsdaleite, a speculative hexagonal carbon polymorph with unique hardness, is expected to happen during violent meteor impacts. Here, we show unprecedente...
The growing production of plastic waste and improper dumping after use has become a worldwide challenge. This is substantial source petroleum can be effectively converted into pyrolytic oil other useful products. A statistical prediction the rate constants essential for optimizing pyrolysis process parameters, such as activation energy (Ea), frequency factor (Ao), temperature (T), kinetic (k). ...
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
