System Bits: August 13
By Ann Mutschler - 13 Aug, 2013 - Comments: 0

Analyzing ad hoc networks Now that the basic protocols of the Internet are more than 30 years old, network scientists are increasingly turning attention to ad hoc networks in which communications networks set up, on the fly, by wireless devices. Here, unsolved problems still abound. Most theoretical analyses of ad hoc networks have assumed that the communications links within the network ar... » read more

Controlling nanomaterials To find out why some sets of flat nanocrystals arrange themselves in an alternating, herringbone style even though it wasn’t the simplest pattern, University of Pennsylvania researchers turned to experts in computer simulation at the University of Michigan and the Massachusetts Institute of Technology. The result of the collaboration gives nanotechnology research... » read more

Bottom-up nanoribbons Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up — atom by atom. As seen under a microscope, the layers brought onions to mind, according to Rice chemist James Tour, until a colleague suggested flat graphene could never be like an onion. “So I said,... » read more

Photon Chips Harvard University, the Massachusetts Institute of Technology (MIT) and the Vienna University of Technology have devised an all-optical transistor controlled by a single photon. The optical transistor could enable the development of photonic quantum gates and deterministic multi-photon entanglement. For years, researchers have been looking to develop an optical transistor, whe... » read more

Power/Performance Bits: July 9

All-optical transistor Optical computing uses light rather than electricity to perform calculations and is expected to potentially pay dividends for both conventional computers and quantum computers, which are largely hypothetical devices that could perform some types of computations exponentially faster than classical computers. One drawback is that optical computing requires light particl... » read more

Using low-power Wi-Fi to track moving humans Based on a concept similar to radar and sonar imaging, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have created a system capable of seeing people through walls. Previous efforts to develop such a system have involved the use of expensive and bulky radar technology that uses a part of the electromagnetic spectrum on... » read more

Simple Economics
By Jon McDonald - 25 Apr, 2013 - Comments: 0

By Jon McDonald I was watching one of the MIT OpenCourseWare videos the other day. It was one of the lectures on Computer Science. I believe it was Prof. Robert Gallager who made a statement that really got me thinking: “Increasingly, system computational complexity has little impact on cost because of chip technology.” From a hardware perspective I initially had a bit of trouble with t... » read more

How To Make A Brain-On-A-Chip
By Mark LaPedus - 15 Nov, 2012 - Comments: 0

By Mark LaPedus In October, Draper Laboratory and the University of South Florida (USF) disclosed an ambitious plan to develop a brain-on-a-chip. The idea is to devise a “micro-environment’’ that mimics the human brain. Researchers hope to study neurodegenerative conditions such as Alzheimer’s disease, strokes and concussions. The eventual goal is to study the effects of drugs and v... » read more

SPOTLIGHT ON FD-SOI, FINFETS AT IEEE SOI CONFERENCE
;1-4 OCT, NAPA
By Various Writers - 25 Sep, 2012 - Comments: 0

The 38th annual SOI Conference is coming right up. Sponsored by IEEE Electron Devices Society, this is the only dedicated SOI conference covering the full technology chain from materials to devices, circuits and system applications. Chaired this year by Gosia Jurczak (manager of the Memories Program at imec), this excellent conference is well worth attending. It’s where the giants of the ... » read more

DSA: High Stakes Game Of Alphabet Soup
By Ed Sperling - 20 Sep, 2012 - Comments: 0

By Mark LaPedus Directed self-assembly (DSA) is making progress for potential use in semiconductor production, but the industry must make some major advances in a sometimes forgotten and unsung segment—materials. DSA is a complementary patterning technology that makes use of block copolymer materials to enable fine pitches in chip designs. But today’s block copolymers based on poly (MMA... » read more
