Graphene is the material of the future, it could even help us to achieve invisibility. So what could it mean for your smartphone?

Scientists, engineers and tech-addicts everywhere are getting very excited about Graphene. It may sound like the stuff you get in your pencils but this newly discovered material could help us enter an entirely new technological age. Work is already underway to make invisibility a possibility – all thanks to the wonders of Graphene.

We’re already living in an exciting age of communication. With superfast, super accessible and super affordable 3G broadband from providers like Mobi-data we now have access to the online world wherever we are and wherever we’re travelling all over the world. Yet Graphene is set to take us into the realms of science fiction – giving smartphones and tablets the power to bend and flex, making annoying charging up a thing of the past and making our gadgets more or less indestructible.

THE WOODLANDS, Texas – NASA’s Mars rover Curiosity has seen evidence of water-bearing minerals in rocks near where it had already found clay minerals inside a drilled rock.

Last week, the rover’s science team announced that analysis of powder from a drilled mudstone rock on Mars indicates past environmental conditions that were favorable for microbial life. Additional findings presented on March 18 at a news briefing at the Lunar and Planetary Science Conference in The Woodlands, Texas, suggest those conditions extended beyond the site of the drilling.

UD prof leads photonics revolution to help researchers access high-tech foundry services

Michael Hochberg joined the University of Delaware in the spring of 2012 as an associate professor in electrical and computer engineering.

An industry leader in silicon photonics and large-scale photonic-electronic integration, Hochberg is renowned for establishing Optoelectronic Systems Integration in Silicon (OpSIS), a high-tech foundry service for silicon photonics in which the community shares the cost of fabricating complex chip-scale systems across many projects.

*Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance*

A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) in collaboration with scientist from University of Notre Dame have determined the origin of the charge-carriers responsible for the ferromagnetic properties that make gallium manganese arsenide such a hot commodity for spintronic devices. Such devices utilize electron spin rather than charge to read and write data, resulting in smaller, faster and much cheaper data storage and processing. (more…)

Earth’s Core Deprived of Oxygen

Washington, D.C. — The composition of the Earth’s core remains a mystery. Scientists know that the liquid outer core consists mainly of iron, but it is believed that small amounts of some other elements are present as well. Oxygen is the most abundant element in the planet, so it is not unreasonable to expect oxygen might be one of the dominant “light elements” in the core. However, new research from a team including Carnegie’s Yingwei Fei shows that oxygen does not have a major presence in the outer core. This has major implications for our understanding of the period when the Earth formed through the accretion of dust and clumps of matter. Their work is published Nov. 24 in Nature. (more…)

Atomic Weights of Ten Chemical Elements About to Change

For the first time in history, a change will be made to the atomic weights of some elements listed on the Table of Standard Atomic Weights of the chemical elements found in the inside covers of chemistry textbooks worldwide.

The International Union of Pure and Applied Chemistry’s (IUPAC) Commission on Isotopic Abundances and Atomic Weights is publishing a new table that will express atomic weights of ten elements as intervals, rather than as single standard values. The new table is the result of cooperative research supported by the U.S. Geological Survey, IUPAC, and other contributing Commission members and institutions. (more…)

*IBM Silicon Nanophotonics uses optical signals to connect chips together faster and with lower power*

Yorktown Heights, N.Y. – 01 Dec 2010: IBM scientists today unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

The new technology, called CMOS Integrated Silicon Nanophotonics, is the result of a decade of development at IBM’s global Research laboratories. The patented technology will change and improve the way computer chips communicate – by integrating optical devices and functions directly onto a silicon chip, enabling over 10X improvement in integration density than is feasible with current manufacturing techniques.
