    MARCY — Danfoss Silicon Power has begun posting job openings for its new facility at the Computer Chip Commercialization Center, also called the Quad-C, on the SUNY Polytechnic Institute campus. The company, based in Germany, is in the preliminary stages of scaling up inside the Quad-C so it can start commercial production in the first quarter of next year, according to site general manager Michael Hennessey. “With a little luck and a lot of hard work, that’s our plan,” he said of the timetable. As of Wednesday, the company’s website began showing several positions that specifically list the Oneida County...
  • Mini-nukes and mosquito-like robot weapons being primed for future warfare

    Nanotechnology opens up the possibility to manufacture mini-nuke components so small that they are difficult to screen and detect. Furthermore, the weapon (capable of an explosion equivalent to about 100 tons of TNT) could be compact enough to fit into a pocket or purse and weigh about 5 pounds and destroy large buildings or be combined to do greater damage to an area. "When we talk about making conventional nuclear weapons, they are difficult to make," he said. "Making a mini-nuke would be difficult but in some respects not as difficult as a full-blown nuclear weapon." Del Monte explained that...

    Scientists at UCLA's California NanoSystems Institute and Jonsson Comprehensive Cancer Center have combined their nanotechnology expertise to create a new treatment that may solve some of the problems of using chemotherapy to treat pancreatic cancer. The study, published online in the journal ACS Nano, describes successful experiments to combine two drugs within a specially designed mesoporous silica nanoparticle that looks like a glass bubble. The drugs work together to shrink human pancreas tumors in mice as successfully as the current standard treatment, but at one twelfth the dosage. This lower dosage could reduce both the cost of treatment and the...

    Kurt H. Becker, a professor in the Department of Applied Physics and the Department of Mechanical and Aerospace Engineering, and WeiDong Zhu, a research associate professor in the Department of Mechanical and Aerospace Engineering, are helping develop a new colloidal gold test strip for cardiac troponin I (cTn-I) detection. The new strip uses microplasma-generated gold nanoparticles (AuNPs) and shows much higher detection sensitivity than conventional test strips. The new cTn-I test is based on the specific immune-chemical reactions between antigen and antibody on immunochromatographic test strips using AuNPs. Compared to AuNPs produced by traditional chemical methods, the surfaces of the...

    Using precision lasers, a Nanoscribe 3D printer can print models of the Empire State building in a space the width of a human hair. Watching the machine build through the “lens” of an electron microscope is otherworldly—but the printer’s potential runs beyond microscale model making. Researchers at the Karlsruhe Institute of Technology, led by Jens Bauer, believe such 3D printers may help craft a new generation of materials lighter than water and strong as steel. Today, the sturdiest materials tend to be the densest (like metals), and the least dense materials tend to be the weakest (like foams). Ideally, materials...

    "Nanotechnology-driven manufacturing will change our world in fundamental ways—but we shouldn’t get too worked up about it." In 1959, Richard Feynman delivered a lecture with the provocative title “There’s Plenty of Room at the Bottom." Speaking at a meeting of the American Physical Society at Caltech, the Nobel-laureate-to-be speculated about the possibility of manipulating matter at the atomic level via exquisitely small machines. Would it be possible, Feynman asked, for such machinery to configure atoms themselves, producing atomically precise outputs? Might we one day have billions of submicroscopic factories working in parallel to produce anything and everything we need? It...

    Cheap synthesis offers edge over gold particles for biomedicine and solar cells. In the realm of nanoparticles, gold reigns supreme. Stable and easy to handle, gold nanoparticles have been used to image cells, deliver drugs and detect disease biomarkers. Silver, by contrast, has suffered from a tarnished reputation, because it is more easily oxidized than gold. It is cheaper, but its nanoparticles degrade far too easily for most uses. Two teams of chemists are now burnishing silver’s status. They have independently developed methods to make robust silver nanoparticles on a large scale — and have worked out what makes them...

    Scientists can now experiment at the atomic scale with unprecedented accuracy in new ‘silent’ laboratories in Switzerland. These labs are shielded against all possible forms of background disturbances – external vibrations, acoustic noise, electromagnetic fields and temperature fluctuations. It is hoped that the labs, devised by Emanuel Lörtscher and his team at IBM Zurich, will accommodate the demands of nanotechnology for the next 20–30 years. The labs were designed to screen all sources of background noise relevant to nanotechnologyWhen probing or building structures at the nanoscale, experimental readings are so tiny that they are easily drowned out by any...

The glass chalice, known as the Lycurgus Cup because it bears a scene involving King Lycurgus of Thrace, appears jade green when lit from the front but blood-red when lit from behind -- a property that puzzled scientists for decades after the museum acquired the cup in the 1950s. The mystery wasn’t solved until 1990, when researchers in England scrutinized broken fragments under a microscope and discovered that the Roman artisans were nanotechnology pioneers: They’d impregnated the glass with...

    Nickel oxide nanoparticles glued together with ultrasound lost none of their catalytic activity © Wiley-VCHResearchers are using ultrasound to bond nanoparticles – essentially sticking together particles too small to be seen with sounds too high-pitched to be heard. The technique apparently preserves the special properties of nanomaterials, while producing micro-scale particles that are easier to handle.Jake Barralet at McGill University in Montreal, Canada, and colleagues show they can take nanoparticles, coat them in phosphate and then weld them together in an ultrasonic bath to form microparticles around 200µm in size.A chance discovery, the team initially assumed the phenomenon was...

    Molecular self-assembly, whereby molecules position themselves into defined arrangements, is commonplace in biological systems and nanotechnology. But researchers at MIT are working on so called "4D printing" technology that aims to bring the process up to the macro scale, enabling 3D-printed materials to be programmed to self-assemble into predefined shapes and structures. Just imagine buying some flat-pack furniture, bringing it home and enjoying a coffee whilst you watch it assemble itself. This month, Skylar Tibbits, director of the MIT Self-Assembly lab, was named as one of the six Architectural League winners for collaborative research into programmable materials. The 4D printing...

    DNA-tethered nanorods link up like rungs on a ribbonlike ladder—a new mechanism for linear self-assembly that may be unique to the nanoscale. Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered that DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement-with the rods forming "rungs" on ladder-like ribbons linked by multiple DNA strands-results from the collective interactions of the flexible DNA tethers and may be unique to the nanoscale. The research, described in a paper published online in ACS Nano, a journal of the American...
