Recombination lifetimes in gamma-irradiated silicon
… irradiation at room temperature by cobalt 60 gamma rays. The resistivity of the boron doped samples ranged between 10 and 5000 ohm-cm, and the resistivity of the phosphorus doped samples was between 20 and 220 ohm-cm. Both crucible and floating zone grown materials were investigated. The …

Sterility and immunogenicity of gamma-irradiated respiratory viruses
Gamma (γ)-radiation is a method commonly applied to sterilise pathogens in the biomedical, food and pharmaceutical industries. γ-radiation inactivates pathogens by causing irreparable damage to genomes to prevent replication. However, proteins and other antigenic structures are left mostly intact. …

Characterization of Mechanical Properties of Gamma Irradiated Additively Manufactured Articles for In-Space Manufacturing
… The second chapter is focused on the effects of gamma irradiation on mechanical properties of hybrid materials as an in-space 3D printing feedstock to investigate the forthcoming possibilities of this technology for future space exploration missions. 3D printed testing samples were irradiated at …

Evaluation of γ-Irradiated Peanut Extract as a Proper Immunogen for Immunotherapy in Murine Model of Peanut Allergy
… forms of IgE-mediated food hypersensitivity, and gamma irradiation has been applied widely for the preservation of food. Previous studies indicated that the capacity of IgE to binds to ovalbumin (OVA) and ovamucoid (OM) was profoundly reduced after treatment with a combination of gamma irradiation …

Radiolysis of the Extract from the Sawdust of the Ponderosa Pine
… of Ponderosa pine sawdust were exposed to gamma and ultraviolet radiation. The three solutions, including the original, were checked for antibiotic activity on: Staphylococcus aureus Escherichia coli and Bacillus cereus. Results indicated that each solution inhibited the growth of the …

Rate zonal density gradient ultracentrifugation analysis of repair of radiation damage to the folded chromosome of Escherichia coli
… sucrose gradients after irradiation with 60Co gamma-rays and ultraviolet light (2S4nm). Irradiation both in vivo and in vitro was used as a molecular probe of the constraints on DNA~packaging in the bacterial chromosome. The extremely gentle lysis and unfolding procedures which were developed …

The colonialisation of paint films by microorganisms in the UK and Norway
… film from below. Spruce panels that had been gamma irradiated showed a similar surface colonisation pattern to those untreated. Matrix Assisted Laser Desorption Ionisation Time-of-Flight Mass Spectrometry(MALDI TOF MS) showed that the technique was able to distinguish between spectra generated …

Effect of radiation on silicon and borosilicate glass
… first is a study of the effects of neutron and gamma radiation on the dimensions of two borosilicate glasses, Pyrex® and Hova SD-2®. These two glasses are commonly used as substrates for silicon microelectromechanical (MEMS) devices, and radiation-induced compaction in a substra.te can have …

Development of a novel co-vaccination approach for pneumococcal and influenza infections
… by individual pathogens as well as co-infection. Gamma-irradiation is considered a safe sterilization method, used routinely to sterilize medical devices, pharmaceuticals and most commonly food products. It can also be utilised as an inactivation technique to generate whole cell bacterial and …

Microfludic point of care platforms for the detection of viruses, proteins, and nucleic acids
… off-chip in buffer with Zika genomic RNA and gamma-irradiated samples of zika virus. This assay was then validated off-chip in whole blood, before we tested the on-chip mixing of our microfluidic mixing module and validated its performance compared to off-chip mixing. Finally, we performed the …

Processing of Hemp Fibre Using Enzyme/Fungal Treatment for Composites
… the dried non-retted hemp fibres were gamma irradiated, and then inoculated with white rot fungi for 2 weeks. Chelator/enzyme treatment was achieved by immersing the fresh green non-retted hemp fibres in solutions consisting of either EDTMP.Na5 (ethylene diamine tetra (methylene …

An investigation of high-k materials in metal-insulator-metal capacitor structures
… of the above hafnium silicate capacitors were irradiated with total radiation dosages of 16 krad(Si) and 78 krad(Si). The electrical properties of both samples were characterised and their reliability characteristics were determined. The 16 krad(Si) sample was determined to have excellent …
