New technique creates multifunctional nanomaterials by mixing and matching existing particles

By - October 23, 2013 1 Picture
Researchers at the Brookhaven National Laboratory (BNL) have developed a generalized method of blending two different types of nanoparticles into a single large-scale composite material using synthetic DNA strands. The technique has great potential for designing a vast range of new nanomaterials with precise electrical, mechanical or magnetic properties. Read More

Replicating hardest known biomaterial could lead to better solar cells and batteries

By - January 17, 2013 2 Pictures
Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals, his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.

Hybrid nanomaterial converts light and heat into electricity

By - November 13, 2012 1 Picture
We’ve seen nanomaterials that can be used to convert light into electricity and others that can convert heat into electricity. Now researchers from the University of Texas at Arlington and Louisana Tech University have created a hybrid nanomaterial that can do both. By pairing the material with microchips, the researchers say it could be used in self-powered sensors, low-power electronic devices, and biomedical implants. Read More

MIT breakthrough could lead to paper-thin bullet-proof armor

By - November 12, 2012 2 Pictures
Scientists have theorized that paper-thin composite nanomaterials could stop bullets just as effectively as heavy weight body armor, but progress has been hampered by their inability to reliably test such materials against projectile impacts. Researchers at MIT and Rice University have developed a breakthrough stress-test that fires microscopic glass beads at impact-absorbing material. Although the projectiles are much smaller than a bullet, the experimental results could be scaled up to predict how the material would stand up to larger impacts. Read More

GeS “nanoflowers” could blossom in next-gen solar cells

By - October 11, 2012 1 Picture
Researchers have already turned to the humble sunflower for inspiration to design more efficient Concentrating Solar Power (CSP) plant layouts, and now a team from North Carolina State University has developed a “nanoflower” structure out of germanium sulfide (GeS) that shows great promise for use in energy-storage devices and more efficient solar cells. The secret is the material's ultrathin petals that provide a large surface area in only a small amount of space. Read More

Nanotech versus the pirates: Zyvex Marine unveils the LRV-17

By - July 20, 2012 5 Pictures
The purveyors of fine nanotech-enabled lightweight boats at Zyvex Technologies have been in touch to tell Gizmag about their latest creation, the LRV-17, developed to combat piracy off the coast of Africa. At 17.35 m (57 ft), the LRV-17 is a slightly bigger boat than Zyvex's unmanned Piranha USV, but unlike its piscine predecessor the LRV-17 can support of a crew of six for up to five days. Thanks to its weight, Zyvex claims its 1500 nautical mile (2778 km) range can outdistance other boats of its size by a factor of three - hence LRV, which stands for long-range vessel. Read More

Stanford scientists give new life to Thomas Edison's nickel-iron battery

By - July 8, 2012 6 Pictures
A green, rechargeable battery that is suitable for powering electric vehicles and stationary power storage applications, and that would survive tens of thousands of charge cycles in a useful life of 100 years without loss of capacity. What could be a better innovation for our times? Such a battery has been developed, and recently improved by Stanford researchers. Oh, one other thing. The battery was invented by Thomas Edison in 1901. Read More

Reusable oil-absorbing nanosponges could soak up oil spills

By - April 17, 2012 4 Pictures
Last week we looked at the development of “hydrate-phobic” surfaces that could assist in the containment of oil leaks in deep water. Now, by adding boron to carbon while growing nanotubes, researchers have developed a nanosponge with the ability to absorb oil spilled in water. Remarkably, the material is able to achieve this feat repeatedly and is also electrically conductive and can be manipulated with magnets. Read More

Unmanned nanomaterial Piranha threatens to redefine naval warfare

By - April 10, 2012 12 Pictures
You've heard of UAVs, unmanned remote controlled military aircraft; but what about USVs? Standing for Unmanned Surface Vehicle, a USV is quite simply an unmanned boat, like Zyvex Marine's Piranha concept. We've looked at USVs before, and the Piranha specifically in early 2010; but what was then a prototype under development is now a fully-fledged production craft, having shipped its first unit last November. "Our production facility is closer to rocket science than traditional boat building," says Zyvex Marine VP Byron Nutley of his boat - the only one in the world, it's claimed, that is made out of nanomaterials. But does the Piranha have the technological bite to match the hyperbole, and what does this mean for naval warfare? Read More

Newly developed metallic "micro-lattice" material is world's lightest

By - November 17, 2011 1 Picture
Researchers have created a new metallic material that they claim is the world’s lightest solid material. With a density of just 0.9 mg/cm3 the material is around 100 times lighter than Styrofoam and lighter than the "multiwalled carbon nanotube (MCNT) aerogel" - also dubbed "frozen smoke" – with a density of 4 mg/cm3 that we looked at earlier this year. Despite being 99.99 percent open volume, the new material boasts impressive strength and energy absorption, making it potentially useful for a range of applications. Read More
