Solubility enhancement of hydrophobic drugs via drug-loaded micelles using biodegradable PEG- polyester diblock copolymers

One of the common difficulties with intravenous drug delivery is low solubility of the drug. The requirement for large quantities of saline to dissolve such materials limits their clinical use, and one solution for this problem that has recently generated interest is the formation of drug-loaded micelles.

Ruthenium-based dyes for Dye-sensitized Solar Cells

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
