Inkjet, laser, Memjet? Fast color printers on tap
(AP) -- For a long time, the two choices in desktop printers have been inkjet and laser. This year, a significant twist on the inkjet is hitting the market and promises high speed - think one color page per ...
Miracle light: Can lasers solve the energy crisis?
Next year will mark the 50th birthday of the laser, one of the most productive and widely used mega-inventions of the last century. Scientists hope that 2010 also will see the launch of laser technology's greatest challenge: ...
Lexmark to jettison inkjet printers, 1,700 workers
(AP)—Lexmark is jettisoning its inkjet printers and laying off 1,700 workers as paper becomes increasingly passe in an age of ever-sleeker digital devices and online photo albums on Internet hangouts like Facebook.
10 products that defined Steve Jobs' career
(AP) -- Steve Jobs had no formal schooling in engineering, yet he's listed as the inventor or co-inventor on more than 300 U.S. patents. These are some of the significant products that were created under ...
Eco-friendly wet-strong printing paper made 100% with recycled polyester derived from used PET bottles
Teijin Limited announced today that it has developed a water-resistant, wet-strong printing paper made entirely with the company's ECOPET recycled polyester fiber derived from used PET (polyethylene terephthalate) bottles.
The Shrinky Dink solution
Toys don't usually inspire high-tech innovation, but Michelle Khine's childhood favorite did just that.
Surface emitters set a new world record for spectral bandwidth
German scientists at the TU Darmstadt have developed semiconductor lasers that emit light over a wavelength range of 100 nm, a new world record for a single semiconductor laser. Such lasers might allow more ...
