A 4arm-PEG macromolecule crosslinked chitosan hydrogels as antibacterial wound dressing.
Carbohydrate Polymers, 2021In order to develop better wound dressings, a novel chitosan hydrogel (Cn-Nm gel) was designed and fabricated by using aldehyde-4-arm polyethylene glycol (4r-PEG-CHO) to crosslink the chitosan dissolved in alkaline solution, amino-4-arm polyethylene ...

High price-earnings ratios are often justified by high growth rates in corporate earnings. In recent years, many analysts have turned to the ratio of the PE ratio to the growth rate (the PEG ratio) in an effort to control for this relationship. In fact, the PEG ratio is not a constant that can be used to decide whether a stock is cheap or not.

PEG polymer brushes via the Langmuir–Schaefer technique: The transfer ratio
Journal of Colloid and Interface Science, 2013The 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.

A comprehensive study on shape memory behavior of PEG plasticized PLA/TPU bio-blends
, 2020In this study, the shape memory behavior of poly(ethylene glycol) (PEG) plasticized poly(lactic acid)/thermoplastic polyurethane (PLA/TPU) blends was investigated as functions of PLA/TPU ratio, plasticizer molecular weight and programming conditions. The

Effect of EDA/PEGDGE Mole Ratios on PEG-Based Hydrogel Scaffolds Properties
Advanced Materials Research, 2012The 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.
