Hydrophobic Silic shirt repels sweat and stains

By - December 22, 2013 4 Pictures
We're still a long ways away from the self-drying clothing seen in Back to the Future II, but we may have a useful alternative in the form of a piece of clothing that never gets wet to begin with. Young entrepreneur Aamir Patel has developed the Silic shirt, which is made from a hydrophobic fabric that repels liquids away from it like a force field to keep it from getting wet. Read More

Lithium-air batteries go viral for greater durability and performance

By - November 14, 2013 2 Pictures
In recent years, lithium-air batteries that promise improved power density per pound over lithium-ion batteries have been the subject of much research in the quest to give electronic vehicles greater range. By enlisting the help of a genetically-modified virus, researchers at MIT have found a way to improve the performance and durability of lithium-air batteries, which offer the potential of two to three times the energy density of current lithium-ion batteries.

Grad students build nanometer-resolution atomic force microscope using Lego and 3D printing

By - October 3, 2013 4 Pictures
Scanning atomic force microscopes, first introduced into commerce in 1989, are a powerful tool for nanoscale science and engineering. Capable of seeing individual atoms, commercial AFM prices range between US$10K and $1M, depending on the unit's features and capabilities. During the recent LEGO2NANO summer school held at Tsinghua University in Beijing, a group of Chinese and English students succeeded in making a Lego-based AFM in five days at a cost less than $500.

Scientists make "Impossible Material" ... by accident

By - July 30, 2013 7 Pictures
In an effort to create a more viable material for drug delivery, a team of researchers has accidentally created an entirely new material thought for more than 100 years to be impossible to make. Upsalite is a new form of non-toxic magnesium carbonate with an extremely porous surface area which allows it to absorb more moisture at low humidities than any other known material. "The total area of the pore walls of one gram of material would cover 800 square meters (8611 sq ft) if you would 'roll them out'", Maria Strømme, Professor of Nanotechnology at the Uppsala University, Sweden tells Gizmag. That's roughly equal to the sail area of a megayacht. Aside from using substantially less energy to create drier environments for producing electronics, batteries and pharmaceuticals, Upsalite could also be used to clean up oil spills, toxic waste and residues.

NASA develops new technique to grow super-black coating on 3D components

By - July 17, 2013 5 Pictures
Super-black nanotechnology might sound like something ripped from the pages of a comic book, but instead of being in the hands of a super-villain, it's a NASA-researched technology that is set to make spacecraft instruments more sensitive without increasing their size. John Hagopian, an optics engineer at NASA's Goddard Space Flight Center, and his team have demonstrated the ability to grow a uniform layer of carbon nanotubes on oddly shaped platforms, which will extend the potential of the technology by allowing nanotubes to be grown on 3D components.

Toxic shock syndrome can't hide from fluorescent medical dressing

By - May 24, 2013 2 Pictures
Serious burns can lead to infection and potentially fatal toxic shock syndrome (TSS). Once an infection sets in, it is vital to begin treatment quickly to avoid or minimize a transition to TSS. The problem is, removing dressings to check for infection can be painful, slow the healing process and increase the chance of scarring. A prototype dressing developed by chemists at the University of Bath in the UK alerts doctors to the first signs of infection by glowing under ultraviolet (UV) light. Read More

Thin-film solar cells could become more efficient – thanks to moths' eyes

By - May 17, 2013
Because moths need to use every little bit of light available in order to see in the dark, their eyes are highly non-reflective. This quality has been copied in a film that can be applied to solar cells, which helps keep sunlight from being reflecting off of them before it can be utilized. Now, a new moth eye-inspired film may further help solar cells become more efficient. Read More

Piezoelectric skin provides human-like sense of touch

By - April 30, 2013 3 Pictures
For years now, scientists across the globe have strived to find a method that gives robots an accurate sense of touch, and with good reason. A robot with an improved ability to feel would be better equipped to identify objects, judge its movements with greater care, and perform more tasks overall. In the latest step towards that goal, researchers at Georgia Tech have crafted a new type of touch-reactive material that's sensitive enough to read fingerprints and could provide robots with a sense of touch that resembles our own.
