...start, they are trying to make a rectifier, a simple device for changing the periodically reversing flow of electrons in alternating current (AC) into the one-way flow of direct current (DC). Like the cathode in ordinary vacuum tubes, one end of the molecular rectifier would act as a donor of electrons because it would be made out of a molecule that had a lower binding energy. The other end, carrying a higher binding energy, would serve as an anode, or electron acceptor. Thus, if an external alternating voltage were applied, the large molecule would act as a rectifier...
Achieving the precise spacing between donor and acceptor points to avoid the molecular version of a short circuit may be difficult, Aviram and Ratner admit. But, adds IBM Physicist Philip Seiden, chemists are already skilled at manipulating molecular structure and might be able to build molecular devices that will some day perform all the chores of today's tiny chips...
...Stanford University and treating burn victims by grafting skin from other parts of their bodies onto the injured areas. He had learned from earlier experience that skin taken from a burn victim and kept in culture for up to three months could be successfully grafted back onto its donor-despite its decomposed appearance. But a chance experiment showed that it could also be grafted onto an unrelated recipient. While grafting skin back onto a black man, Summerlin noticed that he also had a piece of cultured white skin in his incubator. With the permission of his patient, he applied...
...foundations and several individuals have rejected requests to fund the estimated $5 million center, Peterson said. President Horner yesterday confirmed a report that a potential donor recently rejected her request for funds...
Alan E. Heimert '49 said he was unaware of any rule prohibiting the acceptance of unsolicited gifts, and Bok, who said he was similarly unaware, approved the gift. Sources said the donor, Alan J. Newmark '50, a New York attorney, was unwilling to give the money to the College as a whole...
