Gamma rays induced modifications in the structural, optical and photoemission properties of PVA/TiO2 nanocomposite films

Autor: Basma A El-Badry, G A Khouqeer, M F Zaki

Publikováno v: Physica Scripta. 98:025821

In the present study, nanocomposite films made of TiO2 (0.01 wt%) nanoparticles (NPs) embedded in polyvinyl alcohol (PVA) polymers were prepared via the solution casting technique. The PVA/TiO2 nanocomposite films were irradiated with several doses o

Using the vronskian to analyse the thermogram of a producing well

Autor: M. F. Zakirov, R. A. Valiullin

Publikováno v: Georesursy, Vol 25, Iss 4, Pp 260-266 (2024)

The functional dependence of thermograms in producing wells has been studied in order to determine the initial temperature distribution along the wellbore. Information about the initial thermal field makes it possible to ensure the reliability of sol

Improving photoluminescence, optical and electrical characteristics of PMMA films with gamma irradiation

Autor: M F Zaki, N Shubayr, R M Radwan, Y Alashban

Publikováno v: Physica Scripta. 96:125880

Polymeric materials are macromolecules, essentially a combination of numerous repeated subunits. Polymers are innovative and advanced materials that currently have a strong impact on our daily lives. In recent years, polymer use has been prominent du

Effect of gamma irradiation on optical and chemical properties of cellulose nitrate thin films

Autor: Rafat M. Amin, Ali Mostafa Ali, M. F. Zaki

Publikováno v: Journal of Adhesion Science and Technology. 31:1314-1327

In this work, cellulose nitrate films were irradiated with different doses of gamma irradiations. The gamma irradiation doses were 25, 55, 120, and 170 kGy. The compositional transformation, optical properties, and morphological changes resulted from

Simulated nucleon–nucleon and nucleon–nucleus reactions in the frame of the cascade exciton model at high and intermediate energies

Autor: Shaker El-Shater, M F Zaki, A. Abdel-hafiez

Publikováno v: Pramana. 84:581-590

In this study, we have used the cascade exciton model (CEM) to investigate different characteristics of nuclear reactions. Number of nucleon–nucleon collisions in Pb+Pb collisions as a function of impact parameter and rapidity distributions of nega
