In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…

length of the hydrocarbon chain in the alcohol increases. At four carbon atoms and beyond, the decrease in solubility is noticeable; a two-layered substance may appear in a test tube when the two are mixed. Consider ethanol as a typical small alcohol. In both pure water and pure ethanol the main intermolecular attractions are hydrogen bonds. The energy released when these new hydrogen bonds form approximately compensates for the energy…

A process is disclosed for separating low molecular weight alcohols, especially ethanol, from aqueous mixtures  The feed mixture contains alcohol and water with an extractive solvent comprising a substituted and unsubstituted phenol having 6 carbon atoms and alcohol containing 2 to 4 carbon atoms.  In the process the upper stream contains water with minimum amount of solvent that is 99.9% and the bottom stream contains alcohol with minimum amount of water.  The temperature of the process is…

In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

carbohydrate was subjected to anaerobic digestion, producing biogas for power generation. However, recent conceptual approach is considering the energetic yield form algal biomass for the co-production of other fermented products (e.g., sugar to ethanol, butanol or other biofuels), as it could improve the economics and sustainability of the whole utilization of algae as a feedstock [45]. Economic considerations and principles of green design recommended that biofuels must be produced…

during the process. Ripped grades are harvested and its pulps are fermented along with its skin and yeast. Over a week’s of fermentation yeast reacts with the sugar within the grapes and convert the sugar into ethanol and carbon dioxide. Carbon dioxide is lost to the atmosphere and ethanol remains. After fermentation, malo-lactic conversion takes place, the malic acid found in grapes is converted by bacteria to lactic acid (Myers, 2014). Grapes are responsible for many of the known health…

by crushing up the fruit and leaving the skins in the mix for a day as the skin has natural yeast which can aid in the fermentation process. The fermentation process occurs in carbon dioxide and oxygen; the mixture is oxidised, and the sugar and ethanol react to form carbon dioxide and ethyl alcohol. The yeast will use up all the oxygen as it ferments the sugars. The process will be sugar…

The major bottleneck for lipid extraction from the wet microalgae is the low extraction efficiency, because of the immiscibility of nonpolar organic solvents with water contained in wet microalgae {Yoo, 2012 #31} {Kim, 2013 #118}. Traditional method for lipid extraction from dry biomass uses a co-solvent system, which consist of a non-polar solvent and polar solvent {Halim, 2012 #7} {Kim, 2013 #118}. When the co-solvent system is directly applied to wet microalgal biomass, the microalgal cells…

There are many different kinds of alcohol, the commonest being called ethyl alcohol. Ethyl alcohol, or ethanol, is present in varying amounts in beers and wines, and in distilled liquors such as whiskey, gin, and rum. Alcohol consumption touches many million people around the world. The use of alcohol depends on an individual’s social, cultural, or religious…

A serious problem affecting society today both directly and indirectly is drinking and driving. People of every age group for whatever reason have been getting behind the wheel of a vehicle after that have consumed more than the legal limit of alcohol. The legal limit Individuals that decide to drink and drive not only put themselves at risk, but additionally become a hazardous threat to citizens that travel the same roadways. The consequences of their decisions can have a lasting impact on…
