Discarded human hair repurposed to make new OLED screens

Technology could really use some more sustainable sources, and now researchers at the Queensland University of Technology (QUT) have turned to an unusual one. The team has shown that human hair from barber shops can be used to create OLED displays.Cont… Continue reading Discarded human hair repurposed to make new OLED screens

Slow-mo video captures motion of single molecules at 1,600 fps

The world of atoms and molecules is tricky to study, not just because it’s so small but because events occur so quickly at that scale. Now, researchers at the University of Tokyo have captured slow motion video of the movements of single molecules at 1… Continue reading Slow-mo video captures motion of single molecules at 1,600 fps

Fuel From Water Using Only an Arc Welder

Water, high currents, blinding balls of plasma, and a highly flammable gas that’s toxic enough to kill you in three minutes if you breathe enough of it. What’s not to love about this plasma-powered water gas generator?

In all seriousness, [NightHawkInLight] is playing with some dangerous stuff here, and he’s …read more

Diamond nanothreads could store thrice the energy of Li-ion batteries

Satisfying the energy needs of a growing population in a sustainable way calls for some inventive solutions, and ones not necessarily limited to the confines of battery chemistry. Solutions to storing energy in mechanical systems instead could include … Continue reading Diamond nanothreads could store thrice the energy of Li-ion batteries

Wood and Carbon Rods Used for This Handsome and Effective Microphone

Anyone who was active in the phreaking scene or was even the least bit curious about the phone system back in the Ma Bell days no doubt remembers the carbon capsule microphone in the mouthpiece of many telephone handsets. With carbon granules sandwiched between a diaphragm and a metal plate, …read more

Simple new method makes graphene “paint” possible

Graphene may be versatile, but there’s one thing it’s not all that good at – dispersing in water. Now, researchers at Umeå University have found a relatively simple way to do it. Graphene oxide is a different form of the material that can make for stab… Continue reading Simple new method makes graphene “paint” possible

How 20th century nuclear testing can help scientists detect art forgeries

Researchers from ETH Zurich have refined a process that can detect modern fakes of paintings by measuring excessive levels of the isotope carbon-14 released into the atmosphere through nuclear testing in the 20th century. The new method requi… Continue reading How 20th century nuclear testing can help scientists detect art forgeries
