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.

Tony Fadell is best known “one of the fathers of the iPod” at Apple, and as the former CEO of Nest. We’ve agreed to forget that he led the Google Glass division for a while, too. Today, news broke that the serial inventor and investor is now working with companies including Samsung Electronics and Foxconn’s […]
The Wall Street Journal is reporting that millennials have learned how to get free TV with a simple antenna, for a one-time cost of about $20. Us old-schoolers have known of this ancient wisdom since, well, forever but have neglected to pass down to the young’uns. But the crazy thing is that it’s not just […]
Toaster ovens are the perfect appliance for small things like toasted sandwiches and roasted garlic (try it!), but anything more involved usually requires a full-sized conventional oven.However, despite its small size, the Wolfgang Puck Pressure Oven can handle anything from baked pastries to broiled meats. This kitchen appliance has a minimal countertop footprint, and cooks […]
The Pry.Me Bottle Opener holds tens of thousands of times its own weight, and you can pick one up now from the Boing Boing Store.This remarkable keychain is considerably smaller than any of your keys, but don’t let that fool you: it can easily open any bottle, and could even tow a trailer full of […]
