مطالعات نظری بر روی ماهیت پیوندهای C→E و E→M در کمپلکس های [NHC→E2H4→M(CO)5] (E=Ge, Sn, Pb, M=Cr, Mo, W)

در این پروژه مطالعات نظری بر روی  ساختار و ماهیت پیوندهای  C EوE M  در برخی از کمپلکس های N-هتروسیکلیک کاربن با فرمول عمومی   [NHC→E2H4→M(CO)5]; (E=Ge, Sn, Pb, M=Cr, Mo, W) در سطح تئوریM06/def2-TZVP  گزارش شده است. انرژی برهمکنش پیوندهای C E  و E M در کمپلکس های فوق  محاسبه و مقادیر حاصل نشان داد که انرژی برهمکنش پیوندهای C→E  و E→M  در حضور اتم M یکسان و با تغییر اتم E از Ge به سمت Pb کاهش می ...

Niobium thin film nanostructures were fabricated using electron beam lithography and a liftoff process involving a four layer resist system. Wires having micrometres in length and below 200nm in width were deposited on an insulating substrate and subsequently thinned by anodisation. The resistance of the wires was monitored in situ and could be trimmed by controlling the anodisation voltage and...

raditionally, the function of a network has been to deliver packets from one endpoint to another. There was a distinct boundary between what is done within the network and what is done by the users. Processing within the network was limited basically to routing, congestion control and quality of service (QoS) schemes. This kind of a network can be regarded as “passive”. Several problems with “p...

It is with great regret we have to record the death of Dr. Edward Mills Grace, which took place on May 20th at Thornbury, after some months of failing health. He was born at Downend on November 28th, 1841, the third son of Henry Mills Grace, a very hard-working country doctor, whose leisure moments in the summer were given up to cricket. The other sons were Henry, Alfred, now at Chipping Sodbur...
