Quantum Physics Has Reopened Zeno’s Paradoxes
Posted by Arthur Brown in category: quantum physics
For thousands of years, scholars pondered the question of how anything can move in our world. The problem seemed to have been solved—until the development of quantum mechanics.

New, more sustainable method for manufacturing microchips and other nanoscale devices
Posted by Dan Breeden in categories: biological, computing, nanotechnology, sustainability
Putting 50 billion transistors into a microchip the size of a fingernail is a feat that requires manufacturing methods of nanometer level precision—layering of thin films, then etching, depositing, or using photolithography to create the patterns of semiconductor, insulator, metal, and other materials that make up the tiny working devices within the chip.
The process relies heavily on solvents that carry and deposit materials in each layer—solvents that can be difficult to handle and toxic to the environment.
Now researchers led by Fiorenzo Omenetto, Frank C. Doble Professor of Engineering at Tufts, have developed a nanomanufacturing approach that uses water as the primary solvent, making it more environmentally compatible and opening the door to the development of devices that combine inorganic and biological materials.

Japan introduces the world’s first green fuel engine with insane power: the end of hydrogen and methanol
Posted by Genevieve Klien in categories: economics, energy
One would not be wrong to note that Toyota’s hydrogen engine exhibits enormous performance characteristics. This engine has the capacity to develop one hundred and fourteen horsepower and one hundred and forty Newton meters of torque and, as such, can be used in different car types.
The power-to-weight ratio is also impressive, at 125 horsepower per ton and CO2 emissions of 144 g/km, the thermal efficiency of the engine is 44%, far higher than any traditional gasoline engine. This high efficiency concerns better fuel economy and fewer emissions. The fueling system can also be said to be one of the peculiarities of the hydrogen engine that Toyota uses.

US creates light-based tech to stabilize hypersonic jet engines
Posted by Genevieve Klien in categories: electronics, military
A new NASA-funded study has revealed for the first time that the airflow in supersonic combusting jet engines can be controlled by an optical sensor.
The finding can lead to more efficient stabilization of hypersonic jet aircraft, according to the study carried out by the researchers at the University of Virginia, School of Engineering and Applied Science.
The research allows operators to control airflow at the speed of light when a ‘shock train’ occurs. A shock train is a condition that precedes engine failure within a scramjet engine.
