Patents Granted for Nanocolumn Technology

IQE plc, a leading global supplier of advanced semiconductor epitaxial wafer products and wafer services to the semiconductor industry, is pleased to announce that NanoGaN Limited, a wholly owned subsidiary of IQE, has been granted two separate patents in relation to its nanocolumn technology for the production of advanced blue and green lasers and LEDs.

Turning down the noise in graphene

Working with the unique nanoscience capabilities of the Molecular Foundry at the Lawrence Berkeley National Laboratory, a multi-institutional team of researchers has developed the first model of signal-to-noise-ratios for low frequency noises in graphene on silica. Their results show noise patterns that run just the opposite of noise patterns in other electronic materials.

Carbon nanotubes and the pursuit of the ultimate body armor

Bullet-proof vests are basically made from high stiffness and toughness, woven or laminated, polymeric fibers stacked in a number of layers. Upon impact of the striking bullet, the fabric material absorbs the energy by stretching of the fibers and the stiff fibers ensure that the load is dispersed over a large area throughout the material. Carbon nanotube is an ideal candidate material for bulletproof vests due to its unique combination of exceptionally high elastic modulus and high yield strain. If one compares these values with those for other fibers suitable for ballistic applications, the enormous potential of CNTs as a candidate material for bullet-proof armor system is quite evident.

The ‘magic’ of tin

The metal tin lacks the value and prestige of gold, silver, and platinum - but to nuclear physicists, tin is magic. Physicists recently reported studies on tin that add knowledge to a concept known as magic numbers while perhaps helping scientists to explain how heavy elements are made in exploding stars.

Timely technology sees tiny transitions

Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them -- and it works over longer timescales.

Nano-Energy Workshop on September 13-14

Sessions and discussions will explore how a wide range of nanotechnology disciplines across chemistry, materials, electrical engineering, physics and photonics are being explored to address the need to improve today's energy efficiencies and even tap into new sources of energy production.

Compact microscope a marvel

A compact microscope invented at Rice University is proving its potential to impact global health. This portable, battery-operated fluorescence microscope, which costs $240, stacks up nicely against devices that retail for as much as $40,000 in diagnosing signs of tuberculosis.

Two innovative LMU projects in physics receive EU funding

Two junior researchers at Ludwig-Maximilians-University (LMU) Munich have been awarded prestigious Starting Grants by the European Research Council (ERC). Professor Dieter Braun and Professor Philip Tinnefeld, both members of the Faculty of Physics, will each receive research funding in the amount of some 1.5 million Euros over the next five years.
