Recent progress in modelling the solvent vapor annealing of thin film block copolymers is examined in the context of a self-consistent field theory framework. Key control variables in determining the final microdomain morphologies include swelling ratio or swollen film solvent volume fraction, swollen film thickness, substrate and vapor atmosphere surface energies, effective volume fraction, an...

Low volatility solvent/non-solvent mixtures were utilized to engineer the structure of poly(3-alkylthiophene) (P3AT) organogels. The ratio of solvent to poor-solvent was manipulated to systematically control the kinetics of self-assembly. Specific solvent mixtures were utilized to produce similar gelation kinetics with polymers of differing alkyl chain length. Simultaneous small angle neutron s...

We report an effective method for bringing about a significant reduction in the lateral leakage current passing through the non-channel region of an organic semiconductor through an organic solvent vapor treatment. The hydroxyl-containing dimethyl-sulfoxide molecules interrupt the bulk charge transport after undergoing solvent vapor treatment and reduce the lateral leakage current effectively, ...

Size dependence of solute diffusivity has been investigated using molecular dynamics simulations for a range of solute radii in a binary mixture consisting of solute and solvent species. We demonstrate that the Stokes-Einstein relationship between self diffusivity and solute radius breaks down over a range of solute-solvent size ratios. This is a result of the previously known Levitation Effect...

In recent years, there has been increasing interest in the functional components of sweet potato because its nutritional and medicinal value. The aim this study is to analyse how much phenolic compounds composition (derived from caffeoylquinic acids) varies as a result cooking. Traditional techniques such as: boiling, oven roasting more processing microwave cooking were tested. Three varieties ...

Extraction of intracellular lipids the oleaginous yeast Yarrowia lipolytica has been systematically studied aiming towards a sustainable extraction process for lipid recovery. Selection suitable industrial (bulk) solvents and parameters that lead to maximization recovery are significant issues be addressed, with applications motivating this study. Biomass from fermentation (MUCL 28849) was used...

Processes for the biotechnological production of kerosene and diesel blendstocks are often economically unattractive due to low yields and product titers. Recently, Clostridium acetobutylicum fermentation products acetone, butanol, and ethanol (ABE) were shown to serve as precursors for catalytic upgrading to higher chain-length molecules that can be used as fuel substitutes. To produce suitabl...

Anthocyanins are phenolic compounds and provide the natural color found in fruit. Fruits contain a distinctive because they anthocyanin compounds. have special property of changing at certain pH which can specifically absorb light from ultraviolet (UV) to violet absorption region, but is stronger visible spectrum. This study describes content several samples fruits that as indicators. The purpo...

This study investigates the role of reagent ratio, solvent composition and temperature on solvothermal synthesis MOF-235(Fe) MIL-101(Fe).

Equilibria of the reaction of molybdenum(VI) with L-aspartic acid (Asp) and L- Glutamic acid(Glu) have been studied by spectrophotometric measurements in mixed solvent systems at an ionicstrength of 0.2 mol/dm3 sodium perchlorate, employed (15, 20, 25, 30± 0.1°C) at pH ranges of 3.2to 5.5 with a high ratio of ligand to metal. The stability constants of the complexes and theresulting free energy...
