We have investigated the hydrogen storage capabilities of scandium decorated holey graphyne, a recently synthesized carbon allotrope, by applying density functional theory and molecular dynamics simulations. observed that one unit cell graphyne can adsorb 6 Sc atoms, each atom up to 5 H$_2$ molecules with an average binding energy desorption temperature -0.36 eV/H$_2$ 464 K, respectively. The g...

The use of the foreign gas, helium, for determination of the pulmonary capacity has been reported previously in preliminary form (1). The present report concerns further experience with this method and comparison of results obtained with results by the Christie method (2) and by the Lassen, Cournand, and Richards modification of the Christie method (3, 4) in normal and emphysematous subjects. F...

H2 is regarded to play a crucial role in the transition from fossil fuel-based energy economy towards an environmentally friendly one. However, storage of still challenging, but palladium (Pd) based materials show exciting properties. Therefore, nanoparticulate Pd has been intensely studied for hydrogen past years. Here, we stabilize nanoparticles by intercalation between inorganic nanosheets h...

Development of hydrogen-fueled vehicles can bring economic and environmental benefits through decreased use of oil, and, consequently, a decrease in air pollution and other greenhouse gases.1 However, one of the most important drawbacks of the use of hydrogen as a fuel is that it has to be stored. There are different techniques to store hydrogen. All those techniques have to meet the provisiona...

Hydrogen desorption and adsorption properties of the fullerene materials C60 , C70, and fullerite ~a mixture of C60 and C70) were measured volumetrically using a Sievert’s apparatus. Over several cycles of isotherm measurements at 77 K, the hydrogen storage capacities of one of the fullerite samples increased from an initial value of 0.4 wt % for the first cycle to a capacity of 4.4 wt % for th...

Mg-based materials have been investigated as hydrogen storage materials, especially for possible onboard storage in fuel cell vehicles for decades. Recently, with the development of large-scale fuel cell technologies, the development of Mg-based materials as stationary storage to supply hydrogen to fuel-cell components and provide electricity and heat is becoming increasingly promising. In this...

Intensive efforts have been devoted to the development of new materials for safe and efficient hydrogen storage. Among them, ammonia-borane appears to be a promising candidate due to its high gravimetric hydrogen storage capacity. Ammonia-borane can release hydrogen on hydrolysis in aqueous solution under mild conditions in the presence of a suitable catalyst. Herein, we report the synthesis of...

Electrical generation from hydrogen, the element with higher energy density per unit mass, requires appropriated materials that can be used in its storage [1]. Palladium, with a high capacity to dissociate, absorb and desorb gaseous hydrogen, has been widely used for hydrogen storage [2], in separation membranes [3] and catalytic hydrogenation [4]. The present DFT calculations on clusters model...
