The thermotropic and lyotropic liquid crystalline phase behaviour of a series of diethanolamide amphiphiles with isoprenoid-type hydrocarbon chains (geranoyl, H-farnesoyl, and phytanoyl) has been investigated. When neat, both H-farnesoyl and phytanoyl diethanolamide form a smectic liquid crystalline structure at sub-zero temperatures. In addition, all three diethanolamides exhibit a glass trans...

The neat and lyotropic liquid crystalline phase behavior of three nonionic diethanolamide amphiphiles with C18 hydrocarbon chains containing one, two or three unsaturated bonds has been examined. This has allowed the effect of degree of unsaturation on the phase behavior of diethanolamide amphiphiles to be investigated. Neat linoleoyl and linolenoyl diethanolamide undergo a transition from a gl...

The contaminants in a beverage product that had been reported to have a strange taste were identified. By comparative analysis with the normal product using liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (LC-QTOF-MS), six unknown compounds were detected in the total ion current chromatograms of the product in question. Detailed analysis of the mass spectra and pr...

conclusions the biosurfactants inhibited the growth of organisms such as pseudomonas aeruginosa, staphylococcus aureus, klebsiella pneumonia and escherichia coli with diethanolamide biosurfactant exhibiting better antibacterial activity than sulphated diethanolamide. results the iodine and saponification values of citrullus lanatus oil were 118.50 ± 0.80 g iodine/100g and 199.10 ± 2.40 mgkoh/g ...

There are three microbes that originated from the roots (Rhizosphere) of cocoa plant ( Theobroma cacao L.) as a potential biofertilizer. This research aimed to specify ability microbial isolates in consortium with addition Biosurfactant Diethanolamide. The were observed using synergism test, molecular and population identification consortium. test showed not mutually antagonistic indicated ther...
