Graphene speakers easily outperform traditional designs

I feel like a broken record – graphene is awesome at this, graphene is awesome at that… graphene is just awesome! A few months ago, we were telling you about the first graphene ear buds, which were really promising, but researchers still had a lot of work to make them commercially viable. Well, they’ve turned it up […]

Breakthrough: first time monolayer graphene made in bulk

We’ve written extensively about graphene here on ZME Science, awarding it much praise and promise. Truly, if you read a bit about what graphene can do [strength, conductivity, cost, etc], you’ll soon learn to love it. So, why aren’t we seeing graphene used everywhere, from computers to aerospace like so many science papers herald its […]

Tiny power generator fueled by spit

In the future, your saliva might power key microelectronics. Researchers at Penn State have devised a micro-sized microbial fuel cells that is power by the organic materials and bacteria present in saliva. The power generated by the tiny fuel cell is very small, though, so don’t expect charging your phone by spitting in it any […]

A new method for filtering light coming from a specific direction

Using only material geometry and interference patterns, MIT researchers have devised a novel way of passing light of any colour only if it comes from a specific angle. Light coming from other directions will be reflected, something which can be desirable in certain applications. Those who could benefit immediately from the findings are solar photovoltaics, detectors […]

3D acoustic cloaking device makes objects undetectable with sound

Using relatively simple perforated sheets of plastic and an extensive amount computation, Duke University researchers have created the world’s first sound invisibility cloak. The cloak diverts sound waves in a way that it conceals both itself, and anything hidden beneath it. The device is, of course, 3D, and it works in the same way, no […]

Spider silk, five times stronger than steel and three times tougher than Kevlar will finally be commercialized

It may be the birth of a new supermaterial – not long ago, spider silk materials were considered science fiction. Despite being a bio-material and basically a protein, spider silk has some amazing properties: it is by weight five times stronger than steel and three times tougher than Kevlar. Just so we’re clear, strength is […]

Graphene proves to be fantastic radio waves absorber

Ultra strong, a fantastic electrical conductor, and even suitable for better beer storage, graphene is dazzling the w0rld with its potential applications. Now, it seems there’s another use to add for the growing list of applications for the atom thick hexagon carbon structure. Scientists at Queen Mary University of London and the Cambridge Graphene Centre found that […]

Carbon nanotube fiber can carry four times more charge than copper

Reliable, well supplied and with years and years of manufacturing experience behind it, copper is the most widespread material used for delivering electrical charge. Some applications warrant more efficient materials, though,  and researchers at Rice recently showed that carbon nanotubes spun into fiber can carry four times as much electrical charge than copper cables of […]

Synthetic muscle made from nylon is 100 times stronger than human muscle

Sometimes, I come across stories or various research that make me wonder “why the heck hasn’t anyone else thought of this before?” We should be grateful, nevertheless, that researchers from University of Texas at Dallas have found a way to manufacture artificial muscle that is up to 100 times stronger than the flimsy tissue that […]

World’s first flexible, conductive and transparent material could lead to foldable phones

A new stretchable and transparent electrical conductor has been created at last, one that could finally allow entirely foldable tech to be made. Finding a material that meets all three conditions was thought  impossible until recently, although there are plenty of materials that meet two of the three. We know of materials, for instances, that are […]
