Surface diagnostics of evaporating droplets of nanosphere suspension: Fano interference and surface pressure.

Physical chemistry chemical physics : PCCP

Kolwas M, Kolwas K, Derkachov G, Jakubczyk D.
PMID: 25673315
Phys Chem Chem Phys. 2015 Mar 14;17(10):6881-8. doi: 10.1039/c5cp00013k.

The evaporation of a single, levitating microdroplet of glycols containing SiO2 nanospheres, both of similar refraction indices, was studied by observing changes in the interference pattern and intensities of polarized and depolarized scattered laser light. The evolution of the...

Two open states of P2X receptor channels.

Frontiers in cellular neuroscience

Rokic MB, Stojilkovic SS.
PMID: 24312007
Front Cell Neurosci. 2013 Nov 14;7:215. doi: 10.3389/fncel.2013.00215.

The occupancy of the orthosteric ligand binding sites of P2X receptor (P2XR) channels causes the rapid opening of a small cation-permeable pore, followed by a gradual dilation that renders the pore permeable to large organic cations. Electrophysiologically, this phenomenon...

Organic soluble and uniform film forming oligoethylene glycol substituted BODIPY small molecules with improved hole mobility.

Judiciously chosen side chains of conjugated molecules have a positive impact on charge transport properties when used as the active material in organic electronic devices. Amongst the side chains, oligoethylene glycols (OEGs) have been relatively unexplored due to their...

Turoctocog alfa pegol (N8-GP) is a glycoPEGylated human recombinant factor VIII for the treatment of hemophilia A. The safety profile of rFVIII, and polyethylene glycols (PEG) technology, is well-established. Conducting long-term toxicity studies in animals using human proteins can...

Reduction and control of domain spacing by additive inclusion: morphology and orientation effects of glycols on microphase separated PS-b-PEO.

J Colloid Interface Sci. 2015 Jul 15;450:141-150. doi: 10.1016/j.jcis.2015.03.022. Epub 2015 Mar 17.

Cylindrical phase polystyrene-b-polyethylene oxide (PS-b-PEO) block copolymer (BCP) was combined with lower molecular weight poly/ethylene glycols at different concentrations and their effect on the microphase separation of BCP thin films were studied. Well-ordered microphase separated, periodic nanostructures were realized...

A rapid analysis of plasma/serum ethylene and propylene glycol by headspace gas chromatography.

SpringerPlus

Ehlers A, Morris C, Krasowski MD.

Springerplus. 2013 May 01;2(1):203. doi: 10.1186/2193-1801-2-203. Print 2013 Dec.

A rapid headspace-gas chromatography (HS-GC) method was developed for the analysis of ethylene glycol and propylene glycol in plasma and serum specimens using 1,3-propanediol as the internal standard. The method employed a single-step derivitization using phenylboronic acid, was linear...

Transport Properties of Cation Exchange Membranes in the Presence of Ether Compounds in Electrodialysis.

Journal of colloid and interface science

Sata T, Tanimoto M, Kawamura K, Matsusaki K.
PMID: 10534389
J Colloid Interface Sci. 1999 Nov 15;219(2):310-319. doi: 10.1006/jcis.1999.6482.

Ether compounds such as ethylene glycols with different molecular weights and crown ethers have good affinity to the cation exchange membranes, sulfonated styrene-divinylbenzene membrane (sodium ion form) and perfluorocarbon sodium sulfonate membrane. The impregnated amount of ethylene glycols in...

A linear relation between the cloud point and the number of oxyethylene units of water-soluble nonionic surfactants valid for the entire range of ethoxylation.

Journal of colloid and interface science

Schott H.
PMID: 12742053
J Colloid Interface Sci. 2003 Apr 01;260(1):219-24. doi: 10.1016/s0021-9797(02)00183-2.

The following linear equation correlates the cloud point (CP) of water-soluble polyoxyethylated nonionic surfactants (NSs) with the average number p of oxyethylene units per molecule: (p - p0)/CP = a + b(p - p0). Here p0 is the smallest...
