Simultaneous Grafting of Poly(Acrylic Acid) and Poly(Ethylene Glycol) onto Chitosan using Gamma Radiation: Polymer Networks for Removal of Textile Dyes

Carreón-Castro, M. D. P.; Caldera-Villalobos, M.; Leal-Acevedo, B.; Herrera-González, A. M. (Chitkara University Publications, 2021-02-10)

Chitosan is a bio-based polyelectrolyte with high potential for wastewater treatment. Chitosan can remove anionic dyes by adsorption but it has low performance in the removal of cationic dyes. In this work, we report the ...
Structural Shielding Design of CT Facility using Monte Carlo Simulation

Yadav, Ashwani Kumar; Huillcara, Basilia Quispe; Ramírez, Pablo Víctor Cerón; Aquino, Modesto Antonio Sosa; Hernández, Miguel Ángel Vallejo (Chitkara University Publications, 2021-02-10)

Radiation application in medicine offers extraordinary benefits. But radiation is like a double-edged sword, it has both benefits and associated risks on the community in contact. To justify the safety of workers and members ...
Simulation of Dose Estimations from Solar Protons: A PMMA-Bi2O3 Shielding Model for Space Exploration

Sajo-Bohus, L.; López, J. A.; Castro-Colin, M. (Chitkara University Publications, 2021-02-10)

Adverse effects of long-term exposure to galactic cosmic radiation (GCR) pose a non negligible obstacle for future space exploration programs; the high-LET-particle-rich environment has an adverse effect on human health. ...
Radon Dose Determination and Radiological Risk in Some Mexican Caves with CR-39 Detectors

Chavarria, A.; Golzarri, J. I.; Espinosa, G. (Chitkara University Publications, 2021-02-10)

Radon (222Rn) is a radioactive gas, from the 238U decay chain, that contributes in large part of the natural radiation dose to which humans are exposed. Radon is the second cause of lung cancer after tobacco. The US-EPA ...
