Shear-mechanical and dielectric measurements on the two monohydroxy (monoalcohol) molecular glass formers 2-ethyl-1-hexanol and 2-butanol close to the glass-transition temperature are presented. The shear-mechanical data are obtained using the piezoelectric shear-modulus gauge method covering frequencies from 1 mHz to 10 kHz. The shear-mechanical relaxation spectra show two processes, which fol...
The aim of this paper is to bring valuable phase equilibria information for the design and operation biolubricant related biofuel product processes. As a result, Vapor-Liquid Equilibrium (VLE) measurements, at different temperatures, pressures global compositions, ternary systems [Ethanol + 2-Ethyl-1-hexanol 1-Dodecanol] 1-Octanol 1-Dodecanol], as well multicomponent system containing these alc...
Heterogeneous esterification of 2-ethyl-1-hexanol and 2-ethyl hexanoic acid using AMBERLYST 15 as solid acid-catalyst in supercritical carbon dioxide (SC-CO2) has been studied. Effect of pressure (150, 200, and 250 bar), temperature (75, 110, and 140 C), flow rate of liquid CO2 (0.4, 0.6, and 0.8 mL.min), type of sample collection, and mole ratio of alcohol to acid (2:1, 1:1, and 1:2) on ester ...
Novel octakis-2[(6-hydroxyhexyl)thio]ethyl-octasilsesquioxane (POSS-S-OH) as well as heptaisobutyl-2[(6-hydroxyhexyl)thio]ethyl-octasilsesquioxane (iBu-POSS-S-OH) were synthesized. POSS structures, bearing both types of groups i.e., 2[(6-hydroxyhexyl)thio]ethyl and the vinyl ones, pendant from the octahedral cage are also described. The synthetic pathway involved thiol-ene click reaction of 6-m...
In this study, volatile compounds were analyzed in five samples of home-made spirit beverage made by the distillation of fermented fruits of cornelian cherry (Cornus mas L.). The major volatile compounds, besides ethanol, identified and quantified were: methanol, acetaldehyde, 1-propanol, ethyl acetate, 2-methyl-1-propanol, 1-butanol, amyl alcohols, 1-hexanol and 2-phenylethanol. The minor vola...
Odor, Not Performance, Dictates Bemisia tabaci's Selection between Healthy and Virus Infected Plants
Although, insect herbivores are generally thought to select hosts that favor the fitness of their progeny, this "mother-knows-best" hypothesis may be challenged by the presence of a plant virus. Our previous study showed that the whitefly, Bemisia tabaci, the obligate vector for transmitting Tomato yellow leaf curl virus (TYLCV), preferred to settle and oviposit on TYLCV-infected rather than he...
