Storage capacity, improve

An LIT has the advantage over a three-dimensional ion trap of much-improved trapping efficiency, increased ion-storage capacity, improved ion-ejection efficiency, faster scan speeds, and improved detection sensitivity.

The Li-Mg-B-N-H structure possesses storage capacity of more than 10 wt.% at around 150-200 "C. However, the reversibility of the hydrogen sorption characteristics was determined using pressure-composition isotherms as shown in Figure 6. From this study, we found reversible hydrogen absorption-desorption behavior (-3-4 wt.%) of the new complex hydride Li-Mg-B-N-H. The improvement in temperature and reversible hydrogen storage capacity were unaffected even after ten... 

Due to the high hydrogen storage capacity of the ammonia molecule (17.7 wt% equal to an energy density of 4,318 Wh kg 1), its decomposition is intensely investigated for COx-free hydrogen production for mobile fuel cell applications [146]. However, compared with the well-established Haber Bosch process for ammonia synthesis, its decomposition is underdeveloped and requires substantial improvements before it can be considered as a practical contribution to the energy supply toolbox. 

Due to its improved efficiency and its economical use of data storage capacities the modified HMBC experiment is a valuable alternative for all those structural problems for which the knowledge of long-range and one-bond connectivities and values of the corresponding coupling constants is essential and for which only small sample amounts are available. 

US DOE is investigating two types of hydrides for solid-state hydrogen storage complex metal hydrides and chemical hydrides. DOE s research on complex metal hydrides is focused on increasing the storage capacity of alanates, extending the durability and cycle lifetime, and improving uptake... 

A Rh on Si02 catalyst promoted with V and Sm showed similar improvements in catalyst performance.522 Sm3+ ions improve the dispersion of Rh and increase CO and H2 uptakes, enhancing the formation of acetaldehyde and acetic acid. Lower-valence V ions have a good H2 storage capacity, thereby increasing the hydrogenation ability of the catalyst and promoting the formation of ethanol.
