The researchers have developed a method for growing combinations of different materials in a needle-shaped crystal called a nanowire.
The researchers have found out how to grow smaller crystals within the nanowire, forming a structure like a crystal rod with an embedded array of gems.
These tiny crystals form in the liquid, but later attach to the nanowire and then become embedded as the nanowire is grown further.
This catalyst mediated docking process can elf-optimiseto create highly perfect interfaces for the embedded crystals.
resulted in complex structures consisting of nanowires with embedded nanoscale crystals, or quantum dots, of controlled size and position. he technique allows two different materials to be incorporated into the same nanowire,
even if the lattice structures of the two crystals don perfectly match, said Hofmann. t a flexible platform that can be used for different technologies. ossible applications for this technique range from atomically perfect buried interconnects to single-electron transistors, high-density memories, light emission, semiconductor lasers,
Contributions from ASU researchers included crystallization and biophysical characterization of the rhodopsin-arrestin constructs and crystals, X-ray data collection and evaluation,
#Speedy crystal sponges to clean up waste Close up of the metal organic framework crystals. New sponge-like crystals that clean up contaminants in industrial waste
and soil can now be made rapidly and for 30 per cent of the cost. CSIRO new method, developed in collaboration with The University of Padova (Italy)
and The University of Adelaide, makes the crystals viable to manufacture for the first time by reducing the production time from up to two days down to as few as 15 minutes.
The crystals are made of extremely porous metal organic frameworks (MOFS) and have an internal storage capacity of 7,
This means that the crystals can filter huge volumes of industrial wastewater, trapping large amounts of contaminants including carcinogenic material and heavy metals.
and cost-effective way to grow metal organic frameworksproducing MOF crystals has traditionally been an energy-intensive process due to the heating and cooling required,
and explore turning the crystals into a sustainable industrial waste management product, Dr Falcaro said. CSIRO has used already MOFS to develop a molecular shell to protect
Semiconductors, usually a solid chemical element or compound arranged into crystals, are used widely for computer chips or for light generation in telecommunication systems.
Liu said. e have not been able to grow different semiconductor crystals together in high enough quality,
High quality crystals can be grown even with large mismatch of different lattice constants. Recognizing this unique possibility early on,
see-through overlay called WYSIPS Crystal (the acronym stands for hat you see is photovoltaic surface that sits between the glass
WYSIPS Crystal marketing director Matthieu de Broca says that Sunpartner is working with Kyocera, which makes a number of ruggedized handsets,
to get WYSIPS Crystal into phones next year. But while De Broca says the energy WYSIPS Crystal can produce depends on the kind of light it exposed tontense natural light will work better than diffuse indoor lightingn its current form it can boost battery life by only about 10 to 15 percent
. t will never be able to produce enough to charge the phone from scratch, he says.
The Birth of a New Wonder Material In the last few years, two-dimensional crystals have emerged as some of the most exciting new materials to play with.
One interesting quirk of their physics is that they can behave as a composite of matter and antimatter inside a crystal
transmitting an elastic energy cue that causes the crystal focal conic domains to line up in concentric circles around the posts.
#Semiconductor crystals could be key to extending Moore Law IBM researchers have developed a process for growing crystals made from semiconductor materials,
The crystals were grown using a technique called template-assisted selective epitaxy (TASE) using metal organic chemical vapour deposition.
It allowed the team to develop defect-free crystals, and to lithographically define oxide templates and fill them via epitaxy, making nanowires, cross junctions,
The transistor is made of a single molecule of phthalocyanine surrounded by ring of 12 positively charged indium atoms placed on an indium arsenide crystal,
