#3d printing of metal with microscale droplets A team of researchers from the University of Twente has found a way to 3d print structures of copper and gold,
Their work is published in Advanced Materials 3d printing is a rapidly advancing field, that is sometimes referred to as the'new cornerstone of the manufacturing industry'.
'However, at present, 3d printing is limited mostly to plastics. If metals could be used for 3d printing as well, this would open a wide new range of possibilities.
Metals conduct electricity and heat very well, and they're very robust. Therefore, 3d printing in metals would allow manufacturing of entirely new devices and components,
such as small cooling elements or connections between stacked chips in smartphones. However, metals melt at a high temperature.
Researchers from FOM and the University of Twente now made a major step towards high-resolution metal printing.

#Mirrorlike display creates rich color pixels by harnessing ambient light (Nanowerk News) Using a simple structure comprising a mirror
researchers have developed a display technology that harnesses natural ambient light to produce an unprecedented range of colors
An article describing their innovative approach appears today in The Optical Society's new high-impact journal Optica("Continuous Color Reflective Displays Using Interferometric Absorption".
"This display technology, which could greatly reduce the amount of power used in multiple consumer electronics products,
the new design helps solve many key problems affecting mobile displays such as how to provide an always-on display function without requiring more frequent battery charging

"said John Hong, a researcher with Qualcomm MEMS Technologies, Inc. and lead author on the Optica paper."
"The incredibly efficient display is able to create a rich palette of colors using only ambient light for viewing,
"Harnessing Ambient Light Typical color displays are essential yet power-hungry components of virtually every digital product with a human-machine interface, from cell phones and computers to home televisions and massive
displays at sporting events. Since even the most energy-efficient models require some form of backlighting, they can quickly draw-down a power supply.
engineers have been exploring ways to replace emissive technologies with displays that can reflect ambient light.
Earlier attempts to create reflective light color displays, however, presented a number of vexing problems.
green and blue of a traditional display. Though adequate for certain applications, the fact that only one-third of the incoming light can be reflected back toward the viewer in a typical reflective RGB format limits the gamut of colors and brightness of the display.
The new display reported in Optica is able to overcome these hurdles by reflecting more of the incoming light
and enabling the full spectrum of visible light to be displayed, including bright white and deep black.
Extending Power and Saving Energy Depending on how the display is used, the power savings can exceed current backlit technologies tenfold.
when a particular image is retained on the display, which then operates like a form of analog memory in a virtually power-free display mode.
The design presented in the paper consists of a panel that is about 1. 5 inches across
Both the resolution and area of the display, however, can be scaled to match those of various mobile devices such as Internet-of-Things (Iot) enabled wearables and smartphones.
"No more squinting at a hard to read display outdoors where we spend much of our time,"noted Hong."
