The development of inexpensive radiation-resistant glass is important for potential applications in displays, optics, and nuclear or space environments. This study considers the γ-ray X-ray resistance glasses relevant to low-cost float (i.e., SiO2–Na2O–CaO–MgO), modified with various concentrations (0 – 10 mol%) Sb2O3. Various doses (0, 0.2, 2.0, 5.0 MGy) γ-rays from decay 60Co nuclei, X-rays g...
Silver montmorillonite conducting polymer composite materials as low-cost oxygen reduction catalysts
today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchersdue to the risk of this transit, which should be considered for development of industries and transportation.therefore, a model that is useful should consider the risk and damage to humanitarianand environmental issues due to transit of hazmat materials. by considering the related cost, thereali...
