Universal parameters of bulk-solvent masks [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances
The bulk solvent is a major component of biomacromolecular crystals that contributes significantly to the observed diffraction intensities. Accurate modelling of the bulk solvent has been recognized as important for many crystallographic calculations.

Polymer/Solvent Interaction Parameters

open access: yesRubber Chemistry and Technology, 1966
Abstract Solutions in which one of the components is a high polymer and the other component is a small-molecule solvent behave in a markedly different manner than do solutions of low molecular weight components. For example, the latter obey Raoult's law if the heat of mixing is negligible; however, many polymer solutions show pronounced ...

Parameters Affecting the Accelerated Solvent Extraction of Polymeric Samples [PDF]

open access: yesAnalytical Chemistry, 1997
Accelerated solvent extraction (ASE) is applied for the extraction of monomers and oligomers from polymeric samples. Two polymers, nylon-6 and poly(1,4-butylene terephthalate), are selected as the model samples. The kinetics of mass transfer in ASE of polymeric samples are discussed.

Solvent Control of Electron Transfer Dynamics [PDF]

open access: yes, 2003
We investigate the charge-transfer-to-solvent (CTTS) dynamics of sodide in several solvents. Since this CTTS system has only electronic degrees of freedom, the dynamics provide a window into how solvent motions control electron ...

Using new solvatochromic parameters to investigate dye-solvent interactions

open access: yes, 2022
Solvatochromic behaviours of triazine substituted dyes were evaluated using a novel approach derived from the red shift index (RsI) and associated solvation energy (ASE).

Solvent-Induced Pathway Complexity of Supramolecular Polymerization Unveiled Using the Hansen Solubility Parameters

open access: yes, 2023
Supramolecular building blocks assembling into helical aggregates are ubiquitous in the current literature, yet the role of solvents in these supramolecular polymerizations often remains elusive.

Optimization and physical performance evaluation of electrospun nanofibrous mats of PLA, PCL and their blends

open access: yesJournal of Industrial Textiles, 2022
The optimization of process parameters such as applied voltage, orifice diameter, solvent system, and solvent ratio for electrospinning of neat polymers, polylactic acid (PLA) and poly (є-caprolactone) (PCL), to obtain uniform, randomly oriented ...

Solvatochromism of naringenin in aqueous alcoholic mixtures [PDF]

open access: yesJournal of the Serbian Chemical Society, 2016
The spectral change of naringenin was studied by Uv-vis spectrophotometric method in binary mixtures of water with methanol, ethanol and 1-propanol at 25°C.

Liquid-Phase Exfoliation of Biochars in Green Solvents and Correlation with Solvent Parameters [PDF]

open access: yes, 2021
Liquid-phase exfoliation (LPE) is a process frequently used to overcome the interactions between layers in layered materials to produce small sheets of material, with remarkable properties and high value applications. Materials are prepared via direct or indirect sonication in a solvent that must be able to effectively disperse and stabilize the ...

Recycling of solvent used in a solvent extraction of petroleum hydrocarbons contaminated soil. [PDF]

open access: yes, 2011
The application of water washing technology for recycling an organic composite solvent consisting of hexane and pentane (4:1; TU-A solvent) was investigated for extracting total petroleum hydrocarbons (TPH) from contaminated soil. The effects of water
