Functioning synthetic blood vessels become the real thing

When a vein or artery gets seriously blocked, a common course of action involves replacing it with part of another blood vessel harvested from elsewhere in the patient's body. While 3D-printed and lab-grown blood vessels show promise as alternatives, scientists from the Vienna University of Technology and Vienna Medical University have developed another option – polymer fabric vessels that transform into biological ones, once implanted.

Prototype system paves way for huge, glasses-free 3D displays

Using red/blue filters (anaglyph), polarized (passive) or LED shutter (active) glasses are relatively simple ways of creating a 3D effect. Creating 3D pictures without viewers having to don any form of eyewear is a little trickier and is made even more so if you want really big 3D effects for a sports stadium or a billboard. To help address this, Austrian scientists working at the Vienna University of Technology (TU Vienna) and the company TriLite Technologies have developed a new kind of display just for this purpose that sends beams of light directly to the viewers’ eyes via a laser and a sophisticated mirror system.

New construction technique allows concrete domes to be "popped up"

There probably aren't many domed concrete structures where you live, and there's a reason for that – they're difficult to build. Doing so usually requires the construction of a supporting wooden structure, that holds the concrete in place while it hardens. Now, however, a team at the Vienna University of Technology has devised a system that allows concrete shell structures to simply be "inflated" and cinched together with a steel cable. Read More

Tungsten diselenide shows potential for ultrathin, flexible, semi-transparent solar cells

Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.

All-optical transistor could be a big leap for quantum computing

Researchers at MIT, Harvard and the Vienna University of Technology have developed a proof-of-concept optical switch that can be controlled by a single photon and is the equivalent of a transistor in an electronic circuit. The advance could improve power consumption in standard computers and have important repercussions for the development of an effective quantum computer. Read More
