Multiple teams of Georgia Tech researchers are utilising cyber techniques to support accelerated materials design. Here are a few of the innovative efforts underway by research teams that include engineers, chemists, physicists, computer scientists, and others.

Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow's computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum compu...

Scientists at Tokyo Tech have developed an approach to control the photoluminescence and solid-state emission of bismuth complexes by complexation with phenylazomethine dendrimers. This research not only sheds light on the structure of a rare, luminescent bismuth complex, but will also be used to advance the potential applications of luminous dendrimers, especially in light harvesting, sensing, electronics, photonics, and nano-medicine.

Featuring a 180:1 precision worm drive, the precision AR59-AV motorised, 30mm clear aperture vertical rotation stage from Optimal Engineering Systems (OES) has deep grove ball bearings for a high resolution of ± 0.001° when microstepping (10 micro steps-per-step).

Stanford engineers have developed a low-cost, plastic-based textile that, if woven into clothing, could cool your body far more efficiently than is possible with the natural or synthetic fabrics in clothes we wear today.Describing their work in Science, the researchers suggest that this new family of fabrics could become the basis for garments that keep people cool in hot climates without air conditioning.

Rapidly becoming an important tool for biological research is lightsheet microscopy. Among its strengths are high speed selective plane acquisition, low phototoxicity to samples and low photo bleaching of fluorophores.

A team of researchers at the Technical University of Munich (TUM) has succeeded in linking graphene with another important chemical group, the porphyrins. Porphyrins are well-known because of their striking functional properties which for example play a central role in chlorophyll during photosynthesis. These new hybrid structures could also be used in the field of molecular electronics, catalysis or even as sensors.

Through a collaboration between the University of Calgary, The City of Calgary and researchers in the United States, a group of physicists led by Wolfgang Tittel, professor in the Department of Physics and Astronomy at the University of Calgary have successfully demonstrated teleportation of a photon over a straight-line distance of six kilometres using The City of Calgary's fibre optic cable infrastructure. The project began with an Urban Allian...

A research team at Empa and ETHZurich has developed single crystals made of lead halide perovskites, which are able to gage radioactive radiation with high precision. Initial experiments have shown that these crystals, which can be manufactured from aqueous solutions or low-priced solvents, work just as well as conventional cadmium telluride semi-conductors, which are considerably more complicated to produce.

Materials scientists have developed a strategy for crafting one-dimensional nanorods from a wide range of precursor materials. Based on a cellulose backbone, the system relies on the growth of block copolymer “arms” that help create a compartment to serve as a nanometer-scale chemical reactor. The outer blocks of the arms prevent aggregation of the nanorods.The produced structures resemble tiny bottlebrushes with polymer “hairs&...
