Traitor bacteria help build graphene water filter that kills other bacteria

Michael Irving January 17, 2019

Water filters get less effective as bacteria builds up on their surface. Now, researchers at Washington University in St. Louis have developed a new type of membrane that reduces such biofouling by actively killing bacteria with graphene – and in an interesting twist, it’s built by bacteria.

Physicists measure how long graphene qubits hover in "alive/dead" superposition

Michael Irving January 1, 2019

Practical quantum computers may be another step closer to reality, thanks again to graphene. The bits of information in quantum computers (qubits) can exist in two states at once, and now researchers have managed to record just how long that superposition state can last in a qubit made of graphene.

Next-gen watch balance springs are grown, not drawn

David Szondy October 30, 2018

Empa has developed a technique for growing tiny springs to specifications using photo-etching and electrochemical depositing in cold, aqueous saline solutions instead of conventional drawing and winding techniques.

The watch springs are electroplated on a gold plated silicon wafer, coated with a light-sensitive paint

MIT punches out cell-sized robots made of graphene

Michael Irving October 23, 2018

MIT engineers recently managed to create cell-sized robots that could collect data about their environment, but were a little tricky to manufacture. Now, the team has found a way to mass produce these synthetic cells (syncells) through controlled fracturing of graphene.

Newly-discovered blue phosphorus could be the next 2D wonder material

Michael Irving October 16, 2018

For a few years scientists have predicted a fifth kind of phosphorus should be possible, but it had yet to be confirmed. Now, researchers in Germany have managed to show that blue phosphorus does exist, and mapped out its different properties.

In blue phosphorus, the atoms arrange themselves in a honeycomb pattern like graphene, but buckled, thanks ...

New material pulls carbon from the air for self-repair

Michael Irving October 11, 2018

It’s not enough to reduce our carbon output – we need to actively remove some from the atmosphere. On a small scale MIT engineers have developed a new material that can suck carbon out of the air and use it to get stronger or patch itself up.

The new hydrogel material (dark green) contains chloroplasts (light green) that let it absorb carbon from ...

Microbial "spacesuits" help bacteria convert CO2 to useful chemicals

Michael Irving October 1, 2018

Researchers at the University of California, Berkeley have now developed “spacesuits” that wrap around bacteria to not only protect them from the elements, but turn them into biohybrids that capture carbon dioxide and turn it into useful chemicals.

Sprayable antennas turn surfaces into ultra-thin, transparent transmitters

Michael Irving September 23, 2018

As crucial as antennas are, the rigid metals they’re made of can limit what devices they can be built into. To help with that, researchers at Drexel University have developed a new kind of antenna that can be sprayed onto just about any surface.

The sprayable antenna is made of MXene, a 2D titanium carbide material, which is extremely conductive ...

"Nuclear pasta" ranked strongest material in the universe

Michael Irving September 18, 2018

Forget steel, forget diamond and even forget graphene – “nuclear pasta” may be the strongest material in the universe. This strange substance is formed in the intense pressures inside neutron stars, and researchers have now run computer simulations to test just how strong it is.
