Fast, cheap and colorful 3-D printing

ScienceDaily.com: Nanotechnology News - 1 августа, 2018 - 19:50
People are exploring the use of 3-D printing for wide-ranging applications, including manufacturing, medical devices, fashion and even food. But one of the most efficient forms of 3D printing suffers from a major drawback: It can only print objects that are gray or black in color. Now, researchers have tweaked the method so it can print in all of the colors of the rainbow.

Sunscreen for dancing molecules

ScienceDaily.com: Nanotechnology News - 1 августа, 2018 - 17:26
This study is the first to use heavy water (D2O) - a form of water that contains deuterium (D) instead of hydrogen - in the field of transmission electron microscopy (TEM). This approach significantly delays sample damage, which is one of the major impediments for broader application of liquid-phase TEM to fragile biological samples.

New type of nanoparticle for drug delivery lasts longer in bloodstream

Nanowerk.com - 1 августа, 2018 - 11:14
Selecting the right packaging to get precious cargo from point A to point B can be a daunting task at the post office. For some time, scientists have wrestled with a similar set of questions when packaging medicine for delivery in the bloodstream: How much packing will keep it safe? Is it the right packing material? Is it too big? Is it too heavy?
