The body electric: Researchers move closer to low-cost, implantable electronics

COLUMBUS, Ohio—New technology under development at The Ohio State University is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.

The first planned use of the technology is a sensor that will detect the very early stages of organ transplant rejection.

When will my computer understand me?

When will my computer understand me?

It's not hard to tell the difference between the "charge" of a battery and criminal "charges." But for computers, distinguishing between the various meanings of a word is difficult.

World's first large(wafer)-scale production of III-V semiconductor nanowire

World's first large(wafer)-scale production of III-V semiconductor nanowire

The research team demonstrated a novel method to epitaxially synthesize structurally and compositionally homogeneous and spatially uniform ternary InAsyP1-y nanowire on Si at wafer-scale using metal-organic chemical vapor deposition (MOCVD). The high quality of the nanowires is reflected in the remarkably narrow PL and X-ray peak width and extremely low ideality factor in the InAsyP1-y nanowire/Si diode.

A coupled numerical hydrodynamic water quality model of the river environment

A coupled numerical hydrodynamic water quality model of the river environment

Because of the combination of environmental change and economic and social development, there are new pressures on the development and use of water resources. After 5 years of innovative research, Professor WANG Jianhua and his group, from the State Key Laboratory of Simulation and Regulation of the Water Cycle in River Basins of the China Institute of Water Resources and Hydropower Research, have developed a new coupled numerical hydrodynamic water quality model of the river environment.

Vegetable oil IS good for you, MU researcher says

Vegetable oil IS good for you, MU researcher says

COLUMBIA, Mo. ¬— A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing.

UC Santa Barbara study provides a new framework for understanding the energetics of ionic liquids

UC Santa Barbara study provides a new framework for understanding the energetics of ionic liquids

(Santa Barbara, Calif.) –– A new study by researchers at UC Santa Barbara provides clues into the understanding of the behavior of the charged molecules or particles in ionic liquids. The new framework may lead to the creation of cleaner, more sustainable, and nontoxic batteries, and other sources of chemical power. The research was published in an early online edition of the Proceedings of the National Academy of Sciences.

Whispering light hears liquids talk

Whispering light hears liquids talk

Ever been to a whispering gallery—a quiet, circular space underneath an old cathedral dome that captures and amplifies sounds as quiet as a whisper? Researchers at the University of Illinois at Urbana-Champaign are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

New all-solid sulfur-based battery outperforms lithium-ion technology

New all-solid sulfur-based battery outperforms lithium-ion technology

Scientists at the Department of Energy's Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies that power today's electronics.

The ORNL battery design, which uses abundant low-cost elemental sulfur, also addresses flammability concerns experienced by other chemistries.

The diabetes 'breathalyzer'

PITTSBURGH—Diabetes patients often receive their diagnosis after a series of glucose-related blood tests in hospital settings, and then have to monitor their condition daily through expensive, invasive methods. But what if diabetes could be diagnosed and monitored through cheaper, noninvasive methods?
