Radiation Induced Damage in GaAs Particle Detectors [PDF]

, 1997
The motivation for investigating the use of GaAs as a material for detecting particles in experiments for High Energy Physics (HEP) arose from its perceived resistance to radiation damage. This is a vital requirement for detector materials that are to be

Cx43 channels and signaling via IP3/Ca2+, ATP, and ROS/NO propagate radiation-induced DNA damage to non-irradiated brain microvascular endothelial cells [PDF]

, 2020
Radiotherapeutic treatment consists of targeted application of radiation beams to a tumor but exposure of surrounding healthy tissue is inevitable.

Inelastic scattering of electrons in water from first principles: cross sections and inelastic mean free path for use in Monte Carlo track-structure simulations of biological damage

Royal Society Open Science, 2022
Modelling the inelastic scattering of electrons in water is fundamental, given their crucial role in biological damage. In Monte Carlo track-structure (MC-TS) codes used to assess biological damage, the energy loss function (ELF), from which cross ...

Biodamage via shock waves initiated by irradiation with ions [PDF]

, 2013
Radiation damage following the ionising radiation of tissue has different scenarios and mechanisms depending on the projectiles or radiation modality. We investigate the radiation damage effects due to shock waves produced by ions.

ATR kinase inhibition induces unscheduled origin firing through a Cdc7-dependent association between GINS and And-1

Nature Communications, 2017
ATR kinase activity is essential for slowing replication forks and preventing DNA replication in cells with DNA damage. Here the authors show that ATR inhibition leads to Cdc7 phosphorylation of GINS, leading to origin firing.

The pristine atomic structure of MoS2 monolayer protected from electron radiation damage by graphene

, 2013
Materials can, in principle, be imaged at the level of individual atoms with aberration corrected transmission electron microscopy. However, such resolution can be attained only with very high electron doses.

Radiation Damage in Macromolecular Crystallography [PDF]

Synchrotron Radiation News, 2015
Radiation damage inflicted on macromolecular crystals during X-ray diffraction experiments remains a limiting factor for structure solution, even when samples are cooled to cryotemperatures (~100 K). Efforts to establish mitigation strategies are ongoing and various approaches, summarized below, have been investigated over the last 15 years, resulting ...
