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...

Confirmation III Experimental M at hem at ics : A Case Study

A bs t ract. On the basis of experiment , two groups arr ived ind ependently at similar conjectures on the na ture of optimal st rategies employed in large random games . The first conjectur e was mad e by Kuhn and Quandt in 1963; the second was mad e by the present authors in 1987. In traditional mathematics such duplication is supe rfluous . In experimental mathematics it may pr ovid e mutual...

Dr. E. M. Grace

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...
