World's First Organic Solar Film Manufacturing with Roll-to-Roll Vacuum Deposition
|
From Heliatek GmbH, August 21, 2012: "Heliatek manufactures energy harvesting components made of flexible solar films based on organic semiconductor materials. They are operating the world's first production line in which organic solar films are manufactured in a roll-to-roll process using vacuum deposition. The company inaugurated its first production facility last March in Dresden. The state-of-the-art manufacturing line is now up and running, with the plant carrying out the scheduled trial production. The first solar films coming out of the line will be used for concrete façade projects as well as for pilots and prototypes with partners."
"'Small molecules' are simply applied to the substrate via  evaporation, in contrast to OPV technology utilizing large molecules (polymers), which require solvents and various printing processes. Very precise laser patterning allows optimal use of the available surface. Innovative roll-to-roll production process offers many advantages, not least of which are the non-toxic fabrication of high-quality solar panels and the high cost-saving potential of mass production."

Improved LEDs and Photovoltaics by Hybridization and Nanostructuring
|
From SPIE Newsroom, June 15, 2012, by David J. Rogers, et al. " There has been rapid industrial development for optoelectronic devices based on alloys of GaN with aluminum and indium (AlInGaN), which span a direct bandgap from deep UV to IR. Improving the efficiency of InGaN-based p-n junctions is a very complex and multifaceted task for a number of reasons. Novel combinations of zinc oxide and gallium nitride offer enhanced efficiency, lifetime, and spectral coverage for next-generation optoelectronic devices.
 Pulsed laser deposition (PLD)-grown ZnO top layers can play/combine roles other than just n-type conduction. This occurs by offering transparent conducting oxide (TCO) functionality. An (Al)ZnO (AZO) layer can double as an indium-free layer for current spreading.Moreover, the replacement of ITO with AZO as a current-spreading layer is desirable from a technical, environmental, and economic perspective in that AZO is easier to fabricate than ITO, and because indium is toxic, relatively expensive, and in short supply.
The PLD ZnO layer also boosts device performance by enhancing light extraction in LEDs and eliminating reflection in PVs. The moth-eye-like ZnO nanoarrays that we developed offer a much higher performance alternative for all visible wavelengths. Moreover, the catalyst-free, self-forming nanostructuring can be realized as a modification of the AZO surface at minimal additional manufacturing cost."

Wearable Fabric Memresistors
|
From Printed Electronics World, June 28, 2012, by Peter Harrop: "We are seeing a return to the larger but thin film, titanium dioxide memristors in the form of fibers, the 12-300 nm layers being variously created by thermal or plasma oxidation, RF sputtering or electrochemical deposition with more conventional printing as a route to value engineering the devices in due course. One of the biggest problems the wearables industry has faced is the problem of power and state. Ultra-low voltage helps but true nonvolatile memory, with the ability to perform simple logic-on-chip, is one of the threshold milestones to achieve. 
A recent paper from AIP NASA's Center for Nanotechnology at Ames Research Center on 'Copper oxide resistive switching memory for e-textiles' gives a good overview of the state of the field. It says, 'Integration of electronics into textiles is an emerging field of research investigating the possibilities of smart fabrics and wearable electronics. The technology commonly referred to as electronic-textile or e-textile aims to promote higher quality of life with built-in elements such as power generator, battery, sensor, computational element, and memory. The power generator embedded in the fabric can charge the battery for powering the sensors, and the sensors can detect biomarkers for various diseases and monitor vital signs of the elderly or individuals in extreme conditions such as soldiers and astronauts, and transmit the information to doctors.'
'We have demonstrated a CuxO resistive switching memory on Cu wire by forming CuxO film through thermal oxidation of the copper wire. The cylindrical morphology of the device can play the role of a fiber of the textile.' Source: Read the full article...

LED Manufacturing Equipment Status Report
|
From Solid State Technology, June 21, 2012: " To support the next cycle of LED manufacturing, tools such as MOCVD, plasma etch, lithography, and others must undergo cost efficiency and yield improvements, says Yole Développement (France). Trends include migrating to larger wafers, silicon substrates, and tools developed specifically for LED fab, rather than retooled from semiconductor manufacturing specs.
The LED market experienced an unprecedented investment cycle in 2010-2011, according to Yole Développement. The resulting overcapacity situation will take 12-18 month to absorb. The next investment cycle, driven by lighting applications, will start in 2013. Expect a more limited cycle due to improvements in fab equipment throughput and yields."

Model Explains the Origin of Friction
|
From Advanced Materials & Processes July 2012 p. 9, : "Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, but the fundamental origin of sliding friction has been unknown. Principal scientist at VTT Technical Research Centre of Finland presents an explanation for the origin of sliding friction between solid objects. The model is the first to enable quantitative calculation of the friction coefficient of materials."

How Nanosilver Zaps Germs
|
From Chemical & Engineering News, July 18, 2012, by Carmen Drahl: " Curious germophobes can rejoice: Researchers have figured out how silver nanoparticles, found in many consumer products, kill bacteria. The culprits are the silver ions the nanoparticles emit, not nanoparticle-specific biological effects. Manufacturers add silver nanoparticles to cosmetics and clothing to kill germs. Yet debate rages about how they work. When exposed to air in an aqueous solution, silver nanoparticles release silver ions, which have known antibacterial properties. Researchers have been unable to rule out a role for the nanoparticles themselves.
Researchers at Rice University have synthesized and tested silver nanoparticles' antimicrobial properties under anaerobic conditions, which prevents release of silver ions. The team found that it was important to add enough silver ions; sub-lethal concentrations boosted bacterial survival rates compared with controls. Sizes, shapes, and coatings for silver nanoparticles do matter, but only because they tune the rate of silver ion release. Because silver can wash away from products and go into the water supply, scientists are concerned about these products' environmental footprint. It might be possible to diminish silver nanoparticles' environmental impact by controlling silver ion release with a responsive polymer coating."

New Vacuum Calibration System: Better, Faster, and Cheaper
|
From NIST, Physical Measurement Laboratory, May 8, 2012: "Industries that depend on high-quality, carefully monitored vacuum for sensitive processes such as microchip fabrication, as well as researchers in numerous technology fields, defense R&D work, and academic science, require high-precision sensors calibrated to authoritative standards. Getting direct NIST traceability for vacuum gauges has been a time-consuming and relatively expensive process. Calibrating a customer gauge against one of the national primary standards usually costs about $5000, with a turnaround time of approximately eight weeks.
 Now even small businesses and labs can take advantage of a new, fully automated calibration system devised by engineers at NIST Low Pressure Manometry in PML's Sensor Science Division. With this Vacuum Comparison Standard or VCS apparatus, they can accommodate up to 10 customer gauges of different types at once, with calibration times in the two- to three-hour range, enabling 'on- demand' service at much lower cost. The system calibrates gauges over five orders of magnitude in pressure; from 0.65 Pa to 130,000 Pa. (Standard atmospheric air pressure is about 101,000 Pa.) The low pressure side covers plasma etching, chemical vapor deposition, and sputtering. On the high side, it covers airplane or helicopter altimeters and barometric sensors that need to be traceable to NIST."

Unraveling Intricate Interactions, One Molecule at a Time
|
From Columbia University's School of Engineering and Applied Science, August 13, 2012: "
A team of researchers led by Applied Physics and Applied Mathematics Associate Professor Latha Venkataraman has succeeded in performing the first quantitative characterization of van der Waals interactions at metal/organic interfaces at the single-molecule level. 
In a study published online in Nature Materials , the team has shown the existence of two distinct binding regimes in gold-molecule-gold single-molecule junctions, using molecules containing nitrogen atoms at their extremities that are attracted to gold surfaces. While one binding mechanism is characterized by chemical interactions between the specific nitrogen and gold atoms, the other is dominated by van der Waals interactions between the molecule and the gold surface.
The team's research was in collaboration with Mark Hybertsen from the Center for Functional Nanomaterials at the U.S. Department of Energy's Brookhaven National Laboratory.

Nano, Photonic Research Gets Boost from 3D Visualization Technology
| | From Eurekalert.org, August 14, 2012, by Argonne National Laboratory: "For the first time X-ray scientists have combined high-resolution imaging with 3-D viewing of the surface layer of material using X-ray vision in a way that does not damage the sample.
This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro- and nano-electronics. This new technique also reduces "guesswork" by eliminating the need for modeling-dependent structural simulation often used in X-ray analysis.
Scientists from the Advanced Photon Source and Center for Nanoscale Materials at the U.S. Department of Energy's (DOE) Argonne National Laboratory have blended the advantages of 3-D surface viewing from grazing-incident geometry scattering with the high-resolution capabilities of lensless X-ray coherent diffraction imaging (CDI). The new technique, an adaptation of existing detector technology, is expected to work at all X-ray light sources."

Patterning Defect-Free Nanocrystal Films with Nanometer Resolution
| From MIT News, August 20, 2012 by David L. Chandler: "Films made of semiconductor nanocrystals - tiny crystals measuring just a few billionths of a meter across - are seen as a promising new material for a wide range of applications. Nanocrystals could be used in electronic or photonic circuits, detectors for biomolecules, or the glowing pixels on high-resolution display screens. They also hold promise for more efficient solar cells.
The size of a semiconductor nanocrystal determines its electrical and optical properties. But it's very hard to control the placement of nanocrystals on  a surface in order to make structurally uniform films. Typical nanocrystal films also have cracks that limit their usefulness and make it impossible to measure the fundamental properties of these materials.
Now, researchers at MIT say they have found ways of making defect-free patterns of nanocrystal films where the shape and position of the films are controlled with nanoscale resolution, potentially opening up a significant area for research and possible new applications."
