Laser-generated electron beams are distinguished from conventional accelerated particles by ultrashort beam pulses in the femtoseconds to picoseconds duration range, and their application may elucidate primary radiobiological effects. The aim of the present study was to determine the dose-rate effect of laser-generated ultrashort pulses of 4 MeV electron beam radiation on DNA damage and repair ...

Using electron beam irradiation to modify the electrical conductivity of graphene films based on defect engineering

Ground lean pork was irradiated by an electron beam or X-rays to compare the effects of two types of radiation generated by a linear accelerator on the quality of Bologna sausage as a model meat product. Raw ground lean pork was vacuum packaged at a thickness of 1.5 cm and irradiated at doses of 2, 4, 6, 8, or 10 kGy by an electron beam (2.5 MeV) or X-rays (5 MeV). Solubility of myofibrillar pr...

S1. Binding surface adsorbates to graphene by electron beam irradiation The low magnification image shown in figure S1a demonstrates the contrast between electron beam irradiated area and pristine area. Figure S1(b) and (c) are magnified images of the yellow and blue boxed regions respectively. The darker contrast dots are the inorganic nanocrystals on the surface of graphene. Panel c shows the...

This paper presents the experimental results obtained during the irradiation process with electron beam of flue gases generated by burning fuel with a high content in sulphur. The ALIN-10 accelerator was used for generating the electron beam. The necessary water was sprayed into the gaseous mixture as fine droplets by the mist pump. The highest removal efficiencies were obtained in the presence...

BACKGROUND AND PURPOSE For several years three-dimensional treatment-planning systems have used pencil beam algorithms in the calculation of electron fields. Nowadays, exact Monte Carlo methods are commercially available, showing good correspondence to experimental results. Clinical examples are investigated to find differences in the dose distribution of treatment plans, which are calculated w...

Abstract A bibliometric approach allowed us to study the global research trend on impact of ionizing irradiations polymers from 1975 2019. The investigation revealed 1,015 publications with growing interest since 1990. is split into three main categories: polymer science, nuclear science technology, and chemistry physical. studied in this are gamma, electron beam, X-ray irradiations. under gamm...

An increasing number of studies have recently reported the rapid degradation of hybrid and all-inorganic lead halide perovskite nanocrystals under electron beam irradiation in the transmission electron microscope, with the formation of nanometer size, high contrast particles. The nature of these nanoparticles and the involved transformations in the perovskite nanocrystals are still a matter of ...

As all the mushrooms, Amanita species experiment several conservation problems, with a post-harvest life limited to a few days. Drying is one of the most used methods in mushrooms preservation. Food irradiation is another possible way to improve food quality and insure its security. Among the emerging irradiation technologies, electron beam has wide application, allowing high throughput, wide f...
