Researchers from the Technical University of Denmark demonstrated a new nanotechnology-based printing technique that produces long-lasting color images on plastic at resolutions up to 127,000 dots per inch, many times more detailed than traditional laser printers. The system uses a laser to alter the structure of nanoscale structures on the plastic material. (A nanometer is one-billionth of a meter; a human hair is around 60,000 nanometers in diameter.) The nanoprinting technique could also lead to new kinds of 3D displays or invisible watermarks. From New Scientist:
The surface of the plastic is shaped so that it has lots of tiny pillars, one roughly every 200 nanometers. A thin film of the element germanium is then spread over the plastic. Heat from a laser melts the germanium on each pillar, morphing its shape and thickness. As a result, it reflects a specific color. The coating protects the shapes of the newly carved nanostructures.
Google is reported to be under investigation by the United States National Labor Relations Board (NLRB.gov) for allegations of discouraging union organizing among workers, and for firing the so-called “Thanksgiving Four.”
Senator and 2020 US presidential candidate Bernie Sanders’ “High-Speed Internet For All” plan, unveiled today, promises $150 billion to build publicly owned broadband networks — and to break the chokehold that Comcast, Verizon, and AT&T have on Americans’ access to information and communication.
The good news: Software like Adobe Premiere Pro, Camtasia and Final Cut Pro has opened up a ton of possibilities for desktop videographers. On the other hand, their use is so widespread that you have to be an expert in them before you can even think about a career in the field. That’s a requirement […]
There are a lot of high-tech drones and RC planes flooding the market lately, and the innovations are coming so fast on each new iteration, most of them forget one crucial thing: Flying these is supposed to be fun. Here’s an alternative that keeps that ethic firmly in mind: The Moskito Smartphone-Controlled Plane. This thing […]
There are few intellectual exercises better than a good game of chess against a capable opponent, which is why a lot of old hands at the gameplay it online. But there’s still nothing like the tactile thrill of moving a knight into checkmate. (Or sweeping the pieces off dramatically when you lose.) That’s why we’re […]
