Like turning coal to diamond, adding pressure to an electrical material enhances its properties. Now, University of Illinois at Urbana-Champaign researchers have devised a method of making ferroelectric thin films with twice the strain, resulting in exceptional performance. Led by Lane Martin, a professor of materials science and engineering, the group published its results in the journal Advanced Materials. Ferroelectric materials, metal oxides with special polarization properties, are...

Obesity Can Be Helped By Lowering Drive Time
2012-12-19 07:04:16

Connie K. Ho for redOrbit.com — Your Universe Online With January coming up, it may be the perfect time to turn over a new leaf with lifestyle resolutions. One of the most popular goals is to lose weight and a new study shows that cutting the commute time in a car could have the same impact as reducing the number of calories consumed. “We´re saying that making small changes in travel or diet choices may lead to comparable obesity reduction, which implies that...

Century-old Assumption Overturned By New Study Of Pipestone Artifacts
2012-12-18 15:33:30

University of Illinois [ Watch A Video About The Hopewell Pipes ] In the early 1900s, an archaeologist, William Mills, dug up a treasure-trove of carved stone pipes that had been buried almost 2,000 years earlier. Mills was the first to dig the Native American site, called Tremper Mound, in southern Ohio. And when he inspected the pipes, he made a reasonable — but untested — assumption. The pipes looked as if they had been carved from local stone, and so he said they were....

Sulfur Compounds In Petroleum Fuels Have Met Their Nano-structured Match
2012-12-17 16:44:59

University of Illinois University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively than traditional materials. Such efficiency could lower costs and improve performance for fuel-based catalysis, advanced energy applications and toxic gas removal. Co-led by Mark Shannon, a professor of mechanical science and engineering at the U. of I. until his death this fall, and chemistry professor Prashant Jain, the...

Engineers Create Roll Up Conductors To Save Chip Space
2012-12-14 13:34:45

University of Illinois On the road to smaller, high-performance electronics, University of Illinois researchers have smoothed one speed bump by shrinking a key, yet notoriously large element of integrated circuits. Three-dimensional rolled-up inductors have a footprint more than 100 times smaller without sacrificing performance. The researchers published their new design paradigm in the journal Nano Letters. “It´s a new concept for old technology,” said team leader...

“Bio-bots” Making Tracks In Synthetic Biology
2012-11-15 19:37:10

University of Illinois They´re soft, biocompatible, about 7 millimeters long — and, incredibly, able to walk by themselves. Miniature “bio-bots” developed at the University of Illinois are making tracks in synthetic biology. Designing non-electronic biological machines has been a riddle that scientists at the interface of biology and engineering have struggled to solve. The walking bio-bots demonstrate the Illinois team´s ability to forward-engineer...

Stickleback's Aggressive Behavior Studied
2012-11-15 18:15:46

University of Illinois at Urbana-Champaign With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away. Now researchers are mapping the genetic underpinnings of the stickleback's aggressive behavior. Armed with tools that allow them to see which genes are activated or deactivated in response to social encounters, a team from the University of Illinois has identified broad patterns of gene activity that...

Nano-manufacturing Improved With Nanometer-scale Diamond Tips
2012-11-14 15:39:36

University of Illinois at Urbana-Champaign One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat.  High speed and high temperature have been known to degrade the tip“¦ until now. “Thermal processing is widely used in manufacturing,” according to William King, the College of Engineering Bliss Professor at...

Disappearing Biocompatible Electronics
2012-09-28 11:33:00

[ Watch the Video: Transient Electronic Circuit ] April Flowers for redOrbit.com - Your Universe Online A research team from Northwestern University, the University of Illinois at Urbana-Champaign and Tufts University has demonstrated "transient electronics" for the first time. Transient electronics are electronic devices that gradually disappear on a specified schedule, whether it is within a few days or six months. The applications for these kinds of electronics are innumerable,...

Low-powered Nanotweezers May Benefit Cellular-level Studies By Demonstrating New Capabilities
2012-09-17 17:08:19

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. “We already know that plasmonic nanoantennas enhance local fields by up to several orders of magnitude, and thus, previously showed that we can use these structures with a regular CW laser source to make...

Word of the Day
  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
