Spherical gold particles are able to ‘drill’ a nano-diameter tunnel in ceramic material when heated. This is an easy and attractive way to equip chips with nanopores for DNA analysis, for example. Researcher Lennart de Vreede of the University of Twente applied a large number of microscopic discs of gold on a surface of silicon dioxide. When heated up for several hours, the gold is moving into the material, perpendicular to the surface, like nanometer-sized spheres.

limpet shells

Slide over spider, there's a new heavyweight in town - the limpet. Researchers from the University of Portsmouth believe that the tiny teeth of these snail-like creatures may be the strongest biological material in the world; even stronger than spider's silk. Made up of a super-hard material known as goethite, the teeth cover the limpet's tongue, and are used to scrape algae from the surface of rocks.

MIT chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone. These inexpensive sensors could be widely deployed, making it easier to monitor public spaces or detect food spoilage in warehouses. Using this system, the researchers have demonstrated that they can detect gaseous ammonia, hydrogen peroxide, and cyclohexanone, among other gases. “The beauty of these sensors is that they are really cheap.

Engineers at Stanford University have created a material that can radiate heat away from buildings and send it directly into space. Composed of layers of silicon dioxide and hafnium oxide atop of a layer of silver, the material is only 1.8 microns thick, which is 50 times thinner than a sheet of paper. The material can reflect sunlight back into space like a mirror and direct heat-bearing infrared rays away from the source and into the cosmos.

Scientists at New York University and the University of Melbourne have developed a method using DNA origami to turn one-dimensional nano materials into two dimensions. Their breakthrough offers the potential to enhance fiber optics and electronic devices by reducing their size and increasing their speed.

Two teams of researchers at the University of New South Wales in Australia made a major breakthrough in quantum computing using silicon. Both teams developed a different method of creating a quantum bit, or qubit, with an accuracy of 99%. Qubits are bits that can exist as a 1 and a 0 at the same time, offering quantum computers the possibility of making simultaneous calculations. One team created an artificial atom containing a nucleus qubit and an electron qubit.

Researchers at Case Western Reserve University are testing a prosthetic arm that could someday help to restore wearers' sense of touch. Contact points on the arm's cuff electrically stimulate nerve bundles in the arm of the wearer that relay sense of touch to the brain. This allows the wearer to feel familiar sensations and control the arm with more dexterity.

Nobel medallion

Recently announced Nobel prizes recognize engineering contributions in the fields of physics and chemistry. The Nobel Prize in Physics was awarded to professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura who developed blue light emitting diodes in the early 1990s. Environmentally-friendly blue LEDs have paved the way for such technologies as colored LED screens and energy-efficient white lamps. Eric Betzig, Stefan W. Hell and William E. Moerner were awarded the Nobel Prize in Chemistry for the development of super-resolved fluorescence microscopy, or nanoscopy.

A new technology being developed by engineers at Carnegie Mellon University's Robotics Institute could reduce the dangerous glare caused by automotive headlights. Instead of a standard headlight or LED cluster, the system uses a Digital Light Processing (DLP) projector that can break the light up in to a million tiny beams. A camera captures images of the road which are then analyzed by a processor. A Spacial Light Modulator (SLM) is used to either dim individual beams of light to reduce glare, or brighten them to illuminate street signs or dark roadways.
