Our results, which are supported by13C CP-MAS NMR, XRD, FT-IR, Raman spectroscopy, TGA, DSC, SEM, AFM, chitinase digestive test and elemental analysis, verify the authenticity of beta-chitin. Further, quantum chemical calculations were conducted on all three allomorphic forms, and, together ...
Quantitative analysis has shown that the main effective components - saponins - are not altered by Co γ irradiation. Ginsenoside-Rgwas not affected by the treatment. Negligible changes were observed in the free carbohydrate contents. Doses of more than 5 kGy caused significant decreases in sulfur...
Gamma spectroscopy is a technique that involves analyzing gamma-ray spectra to determine the enrichment or isotopic composition of a material, commonly used in nondestructive assays in the field of nuclear safeguards. AI generated definition based on: Handbook of Radioactivity Analysis (Third Edition),...
The morphologies of different commercial forms of the copolymer of tetrafluoroethylene with hexafluoropropylene (FEP) were investigated by thermomechanical analysis. Both granules and powders of FEPs have similar morphologies... Yu.,A.,Olkhov,... - 《High Energy Chemistry》 被引量: 0发表: 2011...

In subject area: Chemistry The mean free path is the average distance the gamma ray travels through the material before it undergoes some sort of interaction, such as Compton scattering or the photoelectric effect. From: Handbook of Radioactivity Analysis: Volume 2 (Fourth Edition), 2020 ...
In subject area: Chemistry Gamma irradiation is a sterilization method that uses high-energy γ rays from cobalt-60 to denature proteins and nucleic acids, effectively deactivating microorganisms on medical devices.
