Autor: Yasser S. Soliman, Soad M. Tadros, Wafaa B. Beshir, Gamal R. Saad, Salvatore Gallo, Laila I. Ali, Magdi M. Naoum

Publikováno v: Gels, Vol 8, Iss 4, p 222 (2022)

The dosimetric characteristics of hydrogel dosimeters based on polyacrylamide (PAC) as a capping agent incorporating silver nitrate as a radiation-sensitive material are investigated using UV-Vis spectrophotometry within the dose range 0–100 Gy. Gl

Investigation of Dyed Film Based on Quinaldine Red Dyed Poly(Vinyl Alcohol) and Poly(Vinyl Butyral) for High Dose Dosimetry Applications

Autor: Sayeda Eid, Wafaa B. Beshir

Publikováno v: Open Journal of Polymer Chemistry. :113-116

Dyed polymer films, prepared by a simple technique of casting aqueous solutions of poly(vinyl alcohol) PVA or poly(vinyl butyral) PVB containing quinaldine red (QR) on a horizontal glass plate, are useful as routine high-dose dosimeters. These flexib

Barrier to asymmetric internal rotation, conformational stability, vibrational spectra and assignments, and Ab Initio calculations of n-butane-d0, d5 and d10

Autor: James R. Durig, T. S. Little, Wafaa B. Beshir, Aiying Wang

Publikováno v: Journal of Raman Spectroscopy. 22:683-704

The asymmetric torsional potential function of n-butane has been redefined based on a combination of results obtained from experimental and theoretical calculations. From the vibrational spectra of gaseous n-butane below 500 cm−1 the asymmetric tor

Raman and infrared spectra, conformational stability and Ab initio calculations for n-propylamine

Autor: James R. Durig, Wafaa B. Beshir, S. E. Godbey, T. J. Hizer

Publikováno v: Journal of Raman Spectroscopy. 20:311-333

The Raman (3500–10 cm−1) and infrared (3500–50 cm−1) spectra of gaseous and solid n-propylamine, CH3CH2CH2NH2, and its deuterated analog, CH3CH2CH2ND2, were recorded. Additionally, the Raman spectra of the liquids were measured and qualitativ
