PEG polymer brushes via the Langmuir–Schaefer technique: The transfer ratio

Journal of Colloid and Interface Science, 2013
The Langmuir-Schaefer technique allows horizontal transfer of monolayer films of amphiphilic molecules from an air-water interface to a hydrophobic solid substrate. Spectroscopic ellipsometry has been used to estimate the transfer ratio of Polyethylene Glycol (PEG) polymer brushes prepared by this Langmuir-Schaefer method.

Effect of EDA/PEGDGE Mole Ratios on PEG-Based Hydrogel Scaffolds Properties

Advanced Materials Research, 2012
The synthesis of biocompatible hydrogel based on poly (ethylene glycol) (PEG) and ethylene diamine (EDA) using epoxy-amine chemistry was conducted. PEG was chosen as the base material (or monomer) to synthesise hydrogels in this study due to its high hydrophilicity, biocompatibility and low toxicity properties.

Is PEG Ratio a Better Tool for Valuing the Companies as Compared to P/E Ratio? (A Case Study on Selected Automobile Companies)

International Journal of Banking, Risk and Insurance, 2015
The securities in the capital markets can be analyzed with the help of Fundamental Analysis or Technical Analysis or both. As for many small investors, technical analysis is a complex tool to be used for analyzing the securities, they basically use fundamental analysis in formulating their effective investment strategies.

PEG-based nanocomposite hydrogel: Thermo-responsive sol-gel transition and degradation behavior controlled by the LA/GA ratio of PLGA-PEG-PLGA

Polymer Degradation and Stability, 2018
Abstract The sol-gel transition behavior and the degradation behavior of the nanocomposites consisting of laponite clay nanoparticles and poly( d,l -lactide-co-glycolide)-b-poly(ethylene glycol)-b-poly( d,l -lactide-co-glycolide) (PLGA-PEG-PLGA) triblock copolymers (laponite/PLGA-PEG-PLGA nanocomposites) were studied changing the LA/GA ratios of the ...

Development of CdS nanorods of high aspect ratio under hydrothermal conditions with PEG template

Journal of Crystal Growth, 2011
Abstract Cadmium sulfide (CdS) one dimensional (1D) nanocrystals were prepared using a polyethylene glycol (PEG) assisted hydrothermal synthesis. X-ray diffraction result confirms that the nanorods are of hexagonal structure and the selected area electron diffraction (SAED) identifies the single crystalline nature of the sample.

Thermal and rheological behavior of PEG-based nanocomposites: Effect of filler aspect ratio and size

AIP Conference Proceedings, 2018
In this work, polyethylene glycol (PEG) nanocomposites containing different nanofillers (namely boehmites and hydrotalcites) were prepared through melt compounding and their thermal and rheological behavior was thoroughly investigated. The obtained results showed that the two types of nanofillers interact in a different way with the polymer matrix ...

Optimization of Weight Ratio for DSPE-PEG/TPGS Hybrid Micelles to Improve Drug Retention and Tumor Penetration

Pharmaceutical Research, 2018
To enhance therapeutic efficacy and prevent phlebitis caused by Asulacrine (ASL) precipitation post intravenous injection, ASL-loaded hybrid micelles with size below 40 nm were developed to improve drug retention and tumor penetration.ASL-micelles were prepared using different weight ratios of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine ...
