Whereas an STM
tip can slide a single unladened HB-HBP molecule over a copper surface with ease, it must push harder with each atom the molecule takes on.
We share U S WEST Communications' concerns for reliability and scalability, so we were confident in our recommendation that they select the STM
for their own internal network," said Ed Peverell, senior vice president of Sales and Marketing, N.
The high-speed STM
backbone network has made a significant contribution toward expanding reliable cellular service in the Atlanta metropolitan area.
Umar Javed, Executive Vice President for STM
Group, said, "We chose SMS-Mach6 as our business partner because of their specialized staff and world class teleport facilities, offering access to the SES New Skies NSS-10 satellite.
In 1995, Avouris and his coworkers used electrons from an STM
to selectively snip molecular bonds, those between silicon and hydrogen atoms (SN: 6/24/95, p.
switch will be used in the demonstration -- the STM
/S8 and the STM
/S12 -- to connect to channel extension products from Communications Network Technologies.
employs a very fine tip--only one or a few atoms across--connected to a piezoelectric element, a tiny cylinder that lengthens or shortens minutely as the voltage on it changes.
The nearly $7 million cash infusion from Berjaya is welcomed by STM
also introduced a new inverse multiplexing Multiport Data Module (MDM) that provides a flexible, affordable way to extend STM
intelligent networking capabilities to routers, LANs and host-to-host applications.
Group Executive Vice President, Umar Javed, said, "The addition of a standards based DVB-RCS Satlink product line and technology to STM
's portfolio has enabled us to penetrate the volume driven market for large scale VSAT deployments.
Industry users of STM
equipment include brokerage houses, auto dealers, retailers, publishers, manufacturers, distributors and banks, as well as government agencies and telephone companies.
Now, two physicists have discovered that by adding a bit of electrical and chemical brawn, they can use the STM
tip to pick up and reposition silicon atoms, overcoming the atoms' resistance to such maneuvering.
