mil-53-cu has been synthesized hydrothermally and has been used for the first time for gas separation. mil-53-cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for ch4, co2 and h2 at 30 bar and 298 k. the high ch4 adsorption capacity of mil-53-cu maybe attributed to the high pore volume and large number of open metal sites. the high selectivity for ch4 over co2 (11.5) an...
فرض کنید a یک جبر مثلثی باشد. می گوییم نگاشت دو خطی ?:a×a?a یک دومشتق است اگر نسبت به هر دو مولفه یک مشتق باشد. در این پایان نامه دومشتق جدیدی به نام اکسترمال(extremal) را معرفی می کنیم و نشان می دهیم که تحت شرایط خاصی روی مولفه های جبر a، هر دومشتق a، مجموع یک دومشتق اکسترمال و یک دومشتق داخلی است. سپس، با استفاده از این نتیجه، ساختار دومشتق های جبر های بالا مثلثی بلوکی را مورد بررسی قرار...
