Terminal sterilization of medical devices using vaporized hydrogen peroxide: a review of current methods and emerging opportunities.
Brian McEvoy,Neil J. Rowan +1 more
TL;DR: VH2O2 has operational limitations that create technical challenges for industrial‐scale adoption and underappreciated factors such as the occurrence of nonlinear microbial inactivation kinetic plots that may dictate a need to develop a new standard approach to validate VH2 O2 for terminal sterilization of medical devices.

The effects of high energy electron beam irradiation in air on accelerated aging and on the structure property relationships of low density polyethylene
Kieran A. Murray,James E. Kennedy,Brian McEvoy,Olivier Vrain,Damien Ryan,Richard Cowman,Clement L. Higginbotham +6 more
TL;DR: In this article, the response of low density polyethylene (LDPE) to high energy electron beam irradiation in air (10 MeV) between 25 and 400 kGy was examined and compared to non-irradiated polyethylenes in terms of the mechanical and structural properties.

The effects of high energy electron beam irradiation on the thermal and structural properties of low density polyethylene
Kieran A. Murray,James E. Kennedy,Brian McEvoy,Olivier Vrain,Damien Ryan,Clement L. Higginbotham +5 more
TL;DR: In this article, the effects of high energy electron beam irradiation (10−MeV) on low density polyethylene (LDPE) material were thoroughly examined. And the results demonstrated an occurrence of oxidative degradation due to the formation of carbonyl groups at 1718 cm −1.

Effects of gamma ray and electron beam irradiation on the mechanical, thermal, structural and physicochemical properties of poly (ether-block-amide) thermoplastic elastomers
Kieran A. Murray,James E. Kennedy,Brian McEvoy,Olivier Vrain,Damien Ryan,Richard Cowman,Clement L. Higginbotham +6 more
TL;DR: A comparative study on the two key radiosterilisation methods revealed that the gamma irradiation process produced more adverse effects in the PEBA material in contrast to the electron beam irradation process.

The influence of electron beam irradiation conducted in air on the thermal, chemical, structural and surface properties of medical grade polyurethane
Kieran A. Murray,James E. Kennedy,Brian McEvoy,Olivier Vrain,Damien Ryan,Richard Cowman,Clement L. Higginbotham +6 more
TL;DR: In this paper, modifications to the material characteristics resulting from irradiation were extensively examined through a broad array of analytical techniques, including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and dynamic frequency sweeps (DFW).
