Radiation Exposure of Cardiac Conduction Nodes During Breast Proton Therapy [PDF]

International Journal of Particle Therapy, 2023
Purpose: The exposition of cardiac conduction system during breast radiation therapy has never been studied, despite the increasing use of intensity-modulated radiation therapy, which exposes larger volume to low-dose bath.

Anhydrous Proton Conduction of Soy Protein

International Journal of Electrochemical Science, 2021
Water-soluble soy protein contains a large amount of acidic amino acids, such as glutamic and aspartic acids. Since these acidic amino acids possess the –COOH group in their side chain, the water soluble soy protein acts as an acidic polymer.

Three-dimensional protonic conductivity in porous organic cage solids

Nature Communications, 2016
Proton conduction is a fundamental process for fuel cell development, but three-dimensional proton conduction in crystalline porous solids is rare. Here, the authors report organic molecular cages in which the structure imposes three-dimensional proton ...
