The effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...
متن کاملHydrogen storage in molecular compounds.
At low temperature (T) and high pressure (P), gas molecules can be held in ice cages to form crystalline molecular compounds that may have application for energy storage. We synthesized a hydrogen clathrate hydrate, H(2)(H(2)O)(2), that holds 50 g/liter hydrogen by volume or 5.3 wt %. The clathrate, synthesized at 200-300 MPa and 240-249 K, can be preserved to ambient P at 77 K. The stored hydr...

متن کاملDensity Functional Studies on Crystal Structure and electronic properties of Potassium Alanate as a candidate for Hydrogen storage
Potassium Alanate is one of the goal candidates for hydrogen storage during past decades. In this report, initially the Density Functional Theory was applied to simulate the electronic and structural characteristic of the experimentally known KAlH4 complex hydride. The relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
متن کاملtask-based language teaching in iran: a mixed study through constructing and validating a new questionnaire based on theoretical, sociocultural, and educational frameworks
جنبه های گوناگونی از زندگی در ایران را از جمله سبک زندگی، علم و امکانات فنی و تکنولوژیکی می توان کم یا بیش وارداتی در نظر گرفت. زبان انگلیسی و روش تدریس آن نیز از این قاعده مثتسنی نیست. با این حال گاهی سوال پیش می آید که آیا یک روش خاص با زیر ساخت های نظری، فرهنگی اجتماعی و آموزشی جامعه ایرانی سازگاری دارد یا خیر. این تحقیق بر اساس روش های ترکیبی انجام شده است.پرسش نامه ای نیز برای زبان آموزان ...
