The objects of investigation were single crystals of L-α-alanine, in which radical anion CH3 C˙H CO2− has been formed by radiation induced deamination of alanine. Previously, this stable radical has been spectrally identified (λmax, ε=1100 M−1·cm−1), and its characteristics have found to be identical with characteristics of the same radical obtained by pulse radiolysis in aqueous solution. The mechanism of radical formation in the solid state is not known. Time resolved pulse radiolysis of…

First-principles studies of pure and fluorine substituted alanines
This paper communicates the structural, electronic and optical properties of L-alanine, monofluoro and difluoro substituted alanines using density functional calculations. These compounds exist in…
Solid state radiation chemistry—features important in basic research and applications
Simple EPR/Alanine Dosimeter for Medical Application
TLDR
The results indicated that the de-amination of L-alanine is the main reaction to form the “stable” radical and the AiG-dosimeter gives comparable sensitivity for both low and high radiation doses, and a linear EPR-radiation dose response is observed over a very wide range.
Ectopic expression of CaRLK1 enhances hypoxia tolerance with increasing alanine production in Nicotiana spp.
TLDR
It is proposed that CaRLK1 maintains a persistent hypoxia-resistant phenotype because of its role in regulating cell death under abiotic stress.

Assessing the dosimetric and geometric accuracy of stereotactic radiosurgery
TLDR
The purpose of this work was to identify the variations of SRS practice in the UK and develop a novel method compatible with all practices, capable of assessing the accuracy of delivery, to contribute to safety in S RS delivery, provide confidence through a quality assurance audit and form a basis to support standardisation in SRS.

A thin alanine-polyethylene film dosimetry system with diffuse reflection spectrophotometric evaluation
TLDR
The paper shows the importance of the new experimental approach to free radical research in solid state radiation chemistry, as the alanine-polyethylene composite is superior to the simple ALA/DRS version.
