Abstract
Hydrogen is considered an attractive energy resource because it is eco-friendly in contrast with fossil fuels. Hydrogen storage remains as essential technology for increasing the use of the hydrogen in applications such as hydrogen vehicles and fuel cells. Hydrogen storage requires retaining a high density of hydrogen molecules at ambient..... More

Abstract
The properties and H₂O adsorption characteristics of two types of zeolites (3A and 13X) with the same shape but different element composition were identified. These zeolites are used in gas purification processes to manufacture 9N ultra-pure inert gases for semiconductor process applications. To analyze the shape and microstructure of the..... More
