Evaluation of Bisphenol-A Release from Vacuum formed Retainers after Immersion in Distilled Water using High Performance Liquid Chromatography: A Randomised Clinical Trial [PDF]

Journal of Clinical and Diagnostic Research
Introduction: With the increasing demand for aesthetics, the popularity of Vacuum-formed Retainers (VFRs) has been on the rise. Bisphenol-A (BPA) is added to the polymers to make them clear and tough. BPA is identified as an endocrine disruptor linked to

Aqueous synthesis of Nb-modified SnO2 quantum dots for efficient photocatalytic degradation of polyethylene for in situ agricultural waste treatment

Green Processing and Synthesis, 2021
Low density polyethylene is widely used in agricultural production. It is of low cost and able to significantly improve the quality of fruits. However, its decomposition under natural circumstances needs more than one hundred of years.

Porous polyethylene and proplast [PDF]

, 1984
A comparative animal study showed that, after implantation in skull defects in guinea pigs, porous high-density polyethylene (PHDPE) was substantially better anchored in the bone than Proplast, and had greater stability of form and structure. In Proplast,
