A new processing protocol based on non-halogenated solvent and additive is developed to produce polymer solar cells with power conversion efficiencies better than those processed from commonly used halogenated solvent-additive pair. Morphology studies show that good performance correlates with a finely distributed nanomorphology with a well-defined polymer fibril network structure, which leads ...

This report investigates the use of solvent-solvent extraction for the secondary concentration of lead and thorium. The extraction reagents investigated in this report are: For the lead extraction: diethlyammonium diethyldithiocarbamate (DDDC) For the thorium extraction: trioctylphosphinc oxide (TOPO) and di-(2-ethylhexyl)phosphoric add (HDEHP). For all of the extractions 2-octanone was used as...

Back Cover: In article number 2100585 by Karim Aissou and co-workers, a nanoporous layer of perforated lamellae (PL) is produced on top surface asymmetric triblock terpolymer membranes generated non-solvent induced phase separation. The thickness the PL adjusted varying duration solvent vapor annealing (SVA) treatment.

Non-equilibrium molecular dynamics (NEMD) simulations of energy transfer from vibrationally excited CO(2) to CCl(4) and CH(2)Cl(2) solvent molecules are performed to identify the efficiency of different energy pathways into the solvent bath. Studying in detail the work performed by the vibrationally excited solute on the different solvent degrees of freedom, it is shown that vibration-to-vibrat...

The electronic absorption profiles of 3-cyano-1,5-diarylformazans were recorded in different organic solvents having different polarities. Both macroscopic and microscopic aspects were contemplated to determine the influence of various solute-solvent interactions upon absorption spectral shifts. The effects of solvent polarity on the absorbance profiles of the compounds were evaluated. The mult...

Self-assembly of an achiral porphyrin at the interface between a chiral solvent and an atomically flat substrate renders the monolayer chiral, and a non-racemic solvent can even overrule the intrinsic expression of chirality in the self-assembly of chiral molecules.

acetic acid has been applied as an efficient catalyst and a green solvent for the two–component condensation reaction consisting of benzaldehyde, 2-amino-benzamide. the advantages of this protocol was excellent yield, short reaction time, mild reaction conditions, higher availability, low costs, more environmentally friendly, lack of need for column chromatography and simple work-up procedure. ...

2014 By postulating an approximate analytic form for the force between two colloidal particles arising from the structure of the intervening solvent, the solvent structure contributions to the small angle scattering from colloidal dispersions are analysed within a perturbation theory based on the random phase approximation. The force between two colloidal particles due to the solvent structure ...

An asymmetric microgear will spontaneously and unidirectionally rotate if it is heated in a cool surrounding solvent. The resulting temperature gradient along the edges of the gear teeth translates in a directed thermophoretic force, which will exert a net torque on the gear. By means of computer simulations, the validity of this scenario is proved. The rotational direction and speed are depend...

The sedimentation of an initially inhomogeneous distribution of hard-sphere colloids confined in a slit is simulated using the multi-particle collision dynamics scheme which takes into account hydrodynamic interactions mediated by the solvent. This system is an example for soft matter driven out of equilibrium where various length and time scales are involved. The initial laterally homogeneous ...
