It has been observed that most of the chemical entities have high lipophilicity and poor aqueous solubility, which result in poor bioavailability. In order to improve the bioavailability, the release behavior of such drugs should be improved. Although there are numerous techniques to handle solubility related issue, but they are expensive due to involvement of complicated equipments, advanced m...

At present, gas chromatography–quadrupole mass spectrometry (GC-qMS) is considered the gold standard amongst analytical techniques for fire debris analysis in forensic laboratories worldwide, specifically for the detection and classification of ignitable liquids. Due to the highly complex and unpredictable nature of fire debris, traditional one-dimensional GC-qMS often produces chromatograms th...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
Ionic liquids (ILs) are organic salts that have melting points around room temperature. They have received tremendous attention recently due to their low volatility and subsequent potential to reduce air pollution if used as replacements for volatile organic solvents. As a result, they have the potential to be used in a wide variety of chemical processing applications, including as solvents for...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Current world capacity of hydrocarbon liquefaction is around 400,000 barrels per day, providing a marginal share of the global liquid fuel supply. This study performs a broad review of technical, economic, environmental and supply chain issues related to coal-to-liquids (CTL) and gas-to-liquids (GTL). We find three issues predominate. First, significant amounts of coal and gas would be required...
The dynamics of the noble-gas liquids underlies that of all liquids making them an important prototypical model system. Using optical Kerr-effect spectroscopy we show that for argon, krypton, and xenon, both the librational and diffusional contributions to the spectrum are surprisingly complex. The diffusional relaxation appears as a stretched-exponential, such as widely found in studies of str...
Volatile organic compounds (VOCs) have been found to be a major contributor to air pollution in many chemical and industrial processes. Recently, a new class of solvents–ionic liquids, which are chemically stable and non-volatile liquid organic salts at temperatures less than 100 C, have attracted widespread interest due to its negligible volatility, nonflammability and high ionic conductivity....
