H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
Advanced Functional Materials, EarlyView.H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

The compaction properties of polyethylene glycols
Journal of Pharmacy and Pharmacology, 1985 Abstract The mechanical properties of polyethylene glycol (PEG) powders of different average molecular weights have been characterized in terms of their yield pressure, determined from the densification of compacts by the method of Heckel. The yield pressure was found to be proportional to the molecular weight of the PEG.

Applications of fibrous substrates containing insolubilized phase change polymers [PDF]
Incorporation of polyethylene glycols into fibrous substrates produces several improved functional properties when they are insolubilized by crosslinking with a methylolamide resin or by polyacetal formation by their reaction with glyoxal.
