HoloFlex (2016): Holographic 3D Editor with Teapot

Researchers at the Human Media Lab at Queen’s University have developed the world’s first holographic flexible smartphone. The device, dubbed HoloFlex, is capable of rendering 3D images with motion parallax and stereoscopy to multiple simultaneous users without head tracking or glasses.”HoloFlex offers a completely new way of interacting with your smartphone. It allows for glasses-free interactions with 3D video and images in a way that does not encumber the user.” says Dr. Vertegaal.

HoloFlex features a 1920×1080 full high-definition Flexible Organic Light Emitting Diode (FOLED) touchscreen display. Images are rendered into 12-pixel wide circular blocks rendering the full view of the 3D object from a particular viewpoint...

Using a layer of molybdenum disulfide less than one nanometer thick, researchers in Rice University’s Thomann lab were able to design a system that absorbed more than 35 percent of incident light in the 400- to 700-nanometer wavelength range. Credit: Thomann Group/Rice University

Mechanics know molybdenum disulfide (MoS2) as a useful lubricant in aircraft and motorcycle engines and in the CV and universal joints of trucks and automobiles. Rice University researcher Isabell Thomann knows it as a remarkably light-absorbent substance that holds promise for the development of energy-efficient optoelectronic and photocatalytic devices.

“Basically, we want to understand how much light can be confined in an atomically thin semiconductor monolayer of MoS2,” said Assitant/Prof Thomann...

Schematic to display the mesoporous structures in wood where the cell walls are aligned vertically. After lignin is removed and the index-matching polymer is filled in, the thick (up to centimeter) piece of wood becomes a highly transparent structural material. b) Pictures to show that wood becomes highly transparent after the two steps.

Materials scientist Liangbing Hu and his team at the University of Maryland, College Park, have removed the molecule in wood, lignin, that makes it rigid and dark in color. They left behind the colorless cellulose cell structures, filled them with epoxy, and came up with a version of the wood that is mostly see-thru. “It can be used in automobiles when the wood is made both transparent and high strength.” said Dr. Mingwei Zhu...

Engineers at Oregon State University have found a new way to induce and control boiling bubble formation, that may allow everything from industrial-sized boilers to advanced electronics to work better and last longer. The concept could be useful to either to boil water and create steam more readily, like in a boiler or a clothing iron; or with a product such as an electronics device to release heat more readily while working at a cooler temperature.

“One of the key limitations for electronic devices is the heat they generate, and something that helps dis...
