A method to simulate inhomogeneously irradiated objects with a superposition of 1D models [PDF]

open access: yesA&A, 526, 117 (2011), 2011
In close binary systems the atmosphere of one or both components can be significantly influenced by irradiation from the companion. Often the irradiated atmosphere is simulated with a single-temperature approximation for the entire half-sphere.

Tuning the electrical conductivity of Pt-containing granular metals by postgrowth electron irradiation [PDF]

open access: yes, 2011
We have fabricated Pt-containing granular metals by focused electron beam induced deposition from the $(CH_3)_3CH_3C_5H_4Pt$ precursor gas. The granular metals are made of platinum nanocrystallites embedded in a carbonaceous matrix.

Deformation Behaviour of Ion-Irradiated FeCr: A Nanoindentation Study [PDF]

open access: yes, 2021
Understanding the mechanisms of plasticity in structural steels is essential for the operation of next-generation fusion reactors. Elemental composition, particularly the amount of Cr present, and irradiation can have separate and synergistic effects on the mechanical properties of ferritic/martensitic steels. The study of ion-irradiated FeCr alloys is

H(II) centers in natural silica under repeated UV laser irradiations [PDF]

open access: yesJ. Non-Cryst. Solids 351, 2005, 1770, 2004
We investigated the kinetics of H(II) centers (=Ge'-H) in natural silica under repeated 266nm UV irradiations performed by a Nd:YAG pulsed laser. UV photons temporarily destroy these paramagnetic defects, their reduction being complete within 250 pulses.

Structure Formation and Regulation of Au Nanoparticles in LiTaO3 by Ion Beam and Thermal Annealing Techniques

open access: yesNanomaterials, 2022
The size uniformity and spatial dispersion of nanoparticles (NPs) formed by ion implantation must be further improved due to the characteristics of the ion implantation method.

Radiolysis of NaCl at high and low temperatures: development of size distribution of bubbles and colloids [PDF]

open access: yes, 2006
New experimental results are presented on low temperature irradiation (18 °C) of rock-salt samples which had been exposed to initial doses up to 320 GRad at 100 °C.

Structural changes of Ti3SiC2 induced by helium irradiation with different doses [PDF]

open access: yesApplied Surface Science, 2018, 434, 1210-1216, 2020
In this study, the microstructure changes of Ti3SiC2 MAX phase material induced by helium irradiation and evolution with a sequence of different helium irradiation doses of 5E15, 1E16, 5E16 and 1E17cm-2 at room temperature (RT) were characterized with grazing incidence X-ray diffraction (GIXRD) and Raman spectra analysis. The irradiation damage process

Induction of chromosome shattering by ultraviolet light and caffeine [PDF]

open access: yes, 1981
Synchronized and asynchronously growing cells of a V79 sub-line of the Chinese hamster were either partial-cell irradiation (λ, 254 nm) or laser-UV-microirradiated (λ, 257 nm).

Enhancement of hydroxyapatite dissolution through structure modification by Krypton ion irradiation [PDF]

open access: yesJournal of Materials Science and Technology Volume 38, 1 February 2020, Pages 148-158, 2020
Hydroxyapatite synthesized by a wet chemical route was subjected to heavy Krypton ion irradiation of 4MeV at various fluences. Glancing incidence Xray diffraction results confirmed the phase purity of irradiated HA with a moderate contraction in lattice parameters, and further indicated the irradiation induced structural disorder, evidenced by ...

Proton Radiation Effects on Dark Signal Distribution of PPD CMOS Image Sensors: Both TID and DDD Effects

open access: yesSensors, 2017
Four-transistor (T) pinned photodiode (PPD) CMOS image sensors (CISs) with four-megapixel resolution using 11µm pitch high dynamic range pixel were radiated with 3 MeV and 10MeV protons. The dark signal was measured pre- and post-radiation, with the dark
