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.

Characteristics and cytotoxicity of folate-modified curcumin-loaded PLA-PEG micellar nano systems with various PLA:PEG ratios

International Journal of Pharmaceutics, 2016
Targeting delivery system use natural drugs for tumor cells is an appealing platform help to reduce the side effects and enhance the therapeutic effects of the drug. In this study, we synthesized curcumin (Cur) loaded (D, L Poly lactic - Poly ethylenglycol) micelle (Cur/PLA-PEG) with the ratio of PLA/PEG of 3:1 2:1 1:1 1:2 and 1:3 (w/w) and another ...

Effects of the nanofiller size and aspect ratio on the thermal and rheological behavior of PEG nanocomposites containing boehmites or hydrotalcites

Journal of Thermal Analysis and Calorimetry, 2018
In this work, polyethylene glycol nanocomposites containing different nanofillers (namely hydrotalcites or boehmites, at 5 mass% loading) were prepared by melt compounding. Their morphology and microstructure were assessed by means of SEM and XRD analyses.
