Scientists find upper limit for the speed of sound

“A research collaboration between Queen Mary University of London, the University of Cambridge and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound. The result- about 36 km per second - is around twice …

Project  SMD-flipper

SMD-flipper

“Two stepper motors and an Arduino to turn around an SMD part. For my manual pick and place machine, it would be handy to have a tool that flips SMD parts that are upside down in the storage box. The …

Solar-powered system extracts drinkable water from “dry” air

“MIT engineers have made their initial design more practical, efficient, and scalable. Researchers at MIT and elsewhere have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat …

Soyuz crew launches on ‘ultrafast’ two-orbit flight to space station

“An American astronaut and two Russian cosmonauts have launched to the International Space Station just ahead of and to extend 20 years of a continuous human presence in Earth orbit. Kate Rubins of NASA, together with Sergey Ryzhikov and Sergey …

Stacking and Twisting Graphene Unlocks a Rare Form of Magnetism

“Twisting a monolayer and a bilayer sheet of graphene into a three-layer structure leads to new quantum mechanical states. Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique …

Stretching Makes the Superconductor

“When people imagine “new materials,” they typically think of chemistry. But UConn physicist Ilya Sochnikov has another suggestion: mechanics. Sochnikov works with superconductors. Superconductors are materials that let electricity flow without losing energy. In a normal conductor—say, a power …

Superconductor technology for smaller, sooner fusion

“MIT-Commonwealth Fusion Systems demonstration of new superconducting cable is a key step on the high-field path to compact fusion. Scientists have long sought to harness fusion as an inexhaustible and carbon-free energy source. Within the past few years, groundbreaking …

TEDuino: A Modern TED (264) Series Commodore Datasette

“As part of my Commodore Plus/4 series, chapter three of the user’s manual includes a section on using a Commodore Datasette. In a previous post, I assembled the modern replacement for the Datasette, the Tapuino. “What’s a …

Tetrahedra May Explain Water ‘s Uniqueness

“Researchers at the Institute of Industrial Science at The University of Tokyo sifted through experimental data to probe the possibility that supercooled water has a liquid-to-liquid phase transition between disordered and tetrahedrally structured forms. They found evidence of a critical …

Thermal MagIC: New NIST Project to Build Nano-Thermometers Could Revolutionize Temperature Imaging

“Cheaper refrigerators? Stronger hip implants? A better understanding of human disease? All of these could be possible and more, someday, thanks to an ambitious new project underway at the National Institute of Standards and Technology (NIST). NIST researchers are in …
