Applied Nanotech Holdings Inc announced that its subsidiary, Applied Nanotech Inc (ANI), established a strategic development program with Optomec, Inc, a provider of printed electronics for solar, display, electronic packaging and flexible electronics applications. As a part of the commitment, ANI will install a dedicated Optomec M3D aerosol jet printer at its facilities in order to adapt its copper ink to Optomec's patented ultra high resolution printing technology. By utilizing ANI's copper ink, the Optomec printer will offer the solar, display, flexible circuit and PCB manufacturers contact-free deposition of high quality, low cost metal lines, the companies said. According to the companies, the Optomec printing solution is able to produce much finer lines than is currently possible with traditional screen printing and inkjet printing equipment. The combined ANI/Optomec copper ink printing solution will provide an alternative to silver inks facilitating lower cost, coupled with the promise of higher reliability. Furthermore, ANI's copper inks do not require expensive vacuum installation or inert gas environment lowering the cost of the capital for manufacturing equipment.

Growing a mixed "lawn" of two kinds of nanowires can make a new kind of light-sensing array that could be made in metre-scale sheets. The researchers behind the prototype say such cheap, high-quality image sensors would allow uses not conceivable using today's more expensive technology. Current sensors, such as those found in digital cameras, are made like any other silicon chip - they are carved out from a block of material. The new nanowire sensors are instead built from the bottom up, using chemically-grown nano-sized components. A research team led by Ali Javey, at the University of California, Berkeley, developed the process. They start by growing an unruly "lawn" of nanowires on a surface. The crop is then printed onto another surface, a step that simultaneously tidies them up. "At the first stage, the nanowires are more-or-less standing up, like a bad hair day. But during the printing process, they effectively get combed," says Javey. The nanowires, which are a few tenths of a millimetre long and a few tens of nanometres wide, can be printed onto anything from silicon to plastic or paper. Whatever the surface, it must be prepared with a pattern that guides the nanowires to predetermined locations. To make the functioning sensor, two different "crops" of nanotubes are printed onto the same surface. Cadmium selenide nanowires produce electric charge when hit by light, while those made from silicon-coated germanium act as transistors to amplify that charge.

"Carbon Nanotubes (CNTs) have not yet met commercial expectations from a decade ago, and now hot on its heels is graphene. Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics. IDTechEx market forecasts indicate that CNT and graphene transistors may be commercially available in volume from 2015 onwards, according to the new report \"Carbon Nanotubes and Graphene for Electronics Applications 2011-2021\". According to IDTechEx, the biggest opportunity for both materials is in printed and potentially printed electronics, where the value of these devices that partly incorporate these materials will reach over $44 billion in 2021."

""Our goal is to build rocket engine parts up to 10 times faster and reduce cost by more than 50 percent," said Marshall propulsion engineer and project leader Chris Protz. "We are not trying to just make and test one part. We are developing a repeatable process that industry can adopt to manufacture engine parts with advanced designs. The ultimate goal is to make building rocket engines more affordable for everyone.""

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

These are heady times for the thin-film solar industry. The sector's dominant player, First Solar, has been on a tear of late, recently announcing it would build a second 10 megawatt power plant in Nevada, while Miasole, once thought to be ailing, has staged an impressive comeback, raking in an eye-popping $220 million. Nanosolar has developed a new ultra-fast solar cell printer, and even giants like IBM and Applied Materials have gotten in on the game. In the face of such intense competition, how will HelioVolt, a well-funded outpost of CIGS manufacturing in Texas, fare? The company hopes a new hybrid, super fast CIGS process it has developed in collaboration with the National Renewable Energy Laboratory (NREL), which combines its patented FASST process and NREL's non-vacuum deposition technique, will help even the odds. The Austin, Texas-based company licensed NREL's non-vacuum deposition process, which allows for the quick application of liquid precursors onto a printing plate and substrate, to manufacture its solar cells with a 12.2 percent conversion efficiency at a fraction of the regular cost and in record time - under 6 minutes. Another advantage is that the substrate can be made from a variety of building materials, including glass, metals, plastics and roofing materials.

DuPont Photovoltaic Fluoromaterials (PVFM) announced that it has signed a Technology Licensing Agreement with Toppan Inc. Printing Co. LTD, located in Tokyo, Japan, to commercialize its new backsheet for solar photovoltaic (PV) modules. This technical and business deal with Toppan is in line with the PVFM strategic intent to significantly increase the availability of DuPont Tedlar films and backsheet for the fast growing PV market, according to the company. "This collaboration combines DuPont's proprietary technology for Tedlar polymer in backsheets, with Toppan's unique coating capability," said Kelly Kolliopoulos, global business manager of DuPont's Tedlar Division. "We view the new backsheet technology as complementary to our continuing activities to increase the supply of Tedlar films in order to meet the industry's growth and demand for Tedlar."

Driven by the need for increased speed, portability and wiring density, the interconnect pitch on semiconductor packages, and the corresponding high density interconnect (HDI) substrates, continue to shrink. The combination of filled blind microvias and build-up technology provides a means to achieve the required wiring densities. With the rapid growth of this technology, the use of electrodeposited copper for filling blind microvias has become a widely adopted process for manufacture of both HDI printed circuit boards (PCBs) and also semiconductor package substrates.

Washington, Dec 10 : In an effort to combine the properties of plastics and metals, scientists have developed a composite material, which not only conducts electricity like metals but is also light and inexpensive like plastics. The plastic-metal hybrids will be used in the very places where plastic components are equipped with printed circuit boards, for instance in cars or aircraft.

The research result is interesting in that polymer-protected metal particles can also be used in various electronics applications: various kinds of intelligent patterns can be printed on paper that, in the future, may replace components such as electronics boards.
