A rendering of Oceanix City. Oceanix The United Nations just unveiled a concept for a floating city that can hold around 10,000 residents. The city is built to withstand natural disasters like floods, tsunamis, and hurricanes. The design comes from architect Bjarke Ingels and floating city builder Oceanix. At a roundtable on Wednesday, the UN […]



Nanocrystal ‘factory’ could revolutionize quantum dot manufacturing

March 29th, 2019 at 12:04 pm » Comments Off

  A new system for synthesizing quantum dots across the entire spectrum of visible light drastically reduces manufacturing costs, can be tuned on demand to any color and allows for real-time process monitoring to ensure quality control. NC State researchers have developed a microfluidic system for synthesizing perovskite quantum dots that drastically reduces manufacturing costs, […]



Near-perfect performance in low-cost semiconductors

March 29th, 2019 at 11:58 am » Comments Off

Researchers redefine what it means for low-cost semiconductors, called quantum dots, to be near-perfect and find that quantum dots meet quality standards set by more expensive alternatives. Tiny, easy-to-produce particles, called quantum dots, may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors and medical […]



Refrigerants not required: Flexible metal cooling prototype demonstrates extreme efficiency

March 20th, 2019 at 11:07 am » Comments Off

The prototype heating/cooling system uses the remarkable properties of shape-memory nitinol metals for environmentally friendly cooling and heating A German research team has prototyped an extraordinary heating/cooling system that stresses and unloads nickel-titanium “muscle wires” to create heated and cooled air at twice the efficiency of a heat pump or three times the efficiency of […]
