In Situ Method Optimizes Optical Coatings

From Photonics.com, November 2012, by Allan Jaunzens (Evatec Ltd): "Mass-production techniques including plasma ion-assisted evaporation and sputter already enable manufacture of high-quality optical layers. The thin-film engineer can select from a number of existing control techniques according to the optical application and the hardware installed on the manufacturing equipment, but these all have limitations. For some complex coatings in new emerging applications, even very small variations in deposition conditions may drastically reduce production yields." Existing techniques are quartz monitoring, standard optical monitoring, and broadband optical monitoring. In broadband monitoring all wavelengths are checked. "This is the most complex technique used in production to date with edge accuracies and repeatabilities of less than +/- 0.2 percent." Photonics-com-Jaunzens

A new technique, on-line or in situ re-optimization method, is needed to meet tighter tolerances of new consumer and military applications. Each layer of coating is deposited and monitored. Then layer thicknesses and target spectra for remaining layers are recalculated and the process recipe is modified within seconds. This process is repeated for each newly deposited layer. "This opens up new possibilities for improvement of spectral performance to new levels of accuracy, recovery after abnormal mid-process production errors to avoid lost batches, and commercialization of new complex processes where production yields otherwise would be too low."

Plastic Optics Provide Precision
From Photonics.com, December 1, 2012, by Valerie Coffee: "Polymer optics have long been known for being inexpensive and low in optical quality. The ease of high-volume, low-cost manufacturing meant that just a few decades ago, consumers would find them primarily in disposable toys, diffraction-grating glasses and $5 film cameras. As materials, engineering design and tooling improved between the mid-1990s and the middle of the past decade, plastic grew to be common in more high-end optical applications, including fiber optics, biomedical devices, biometric scanning, and the displays and devices used in defense and homeland security.

This Photonics.com flexibility of plastic optics is in large part the result of polymer optics manufacturers using sophisticated injection-molding and -testing techniques. Injection molding allows a polymer to be replicated from a master or metal inserts into complex optics such as Fresnel lenses, aspheres, toroids, free-form and micro-optics in a cost-effective, high-volume process."

Flexible Silicon Solar-Cell Fabrics May Soon Become Possible
From Pennsylvania State University, December 6, 2012, by Katrina Voss: "For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility of weaving together solar-cell silicon wires to create flexible, curved, or twisted solar fabrics. The findings by an international team of chemists, physicists, and engineers, led by John Badding, a professor of chemistry at Penn State University, will be posted by the journal Advanced Materials in an early online edition on 6 December 2012 and will be published on a future date in the journal's print edition.
Penn State University Badding
The team's new findings build on earlier work addressing the challenge of merging optical fibers with electronic chips -- silicon-based integrated circuits that serve as the building blocks for most semiconductor electronic devices such as solar cells, computers, and cell phones."

Sliding Metals Show Fluid-Like Behavior
From Green Car Congress, September 13, 2012:  "Researchers at Purdue have discovered a swirling, fluid-like behavior in a solid piece of metal sliding over another. Numerous mechanical parts from bearings to engine pistons undergo such sliding, and the new insights into the mechanisms of wear and generation of machined surfaces could help improve the durability of these metal parts.
Purdue University/N. Sundaram
Using in situ imaging, including a microscope and high-speed camera, the researchers found bumps, folds, vortex-like features and cracks forming on the metal surface-phenomena normally associated with fluids, not solids, said Srinivasan Chandrasekar, a Purdue University professor. The findings were surprising because the experiment was conducted at room temperature and the sliding conditions did not generate enough heat to soften the metal. It was the first time researchers had directly imaged how sliding metals behave on the scale of 100 microns to 1 millimeter, known as the mesoscale."

The findings are detailed in an open access paper published in Physical Review Letters 109, 106001 doi.

Platinum Plating at the Flick of a Switch
From Chemistry World, December 10, 2012, by Phillip Broadwith: "Atom thick catalytic layers of platinum can be deposited on surfaces from solution rapidly and cheaply thanks to a new technique developed by US scientists. The quality of the films produced is comparable to those produced by vapour atomic layer deposition, but uses a much simpler process."

"Atomically thin films of platinum can already be made using vapour deposition or molecular beam epitaxy, Moffat acknowledges, but these techniques involve expensive high vacuum chambers and each layer forms quite slowly as the added atoms skate around on the surface to find low energy sites. 'We're essentially using beaker chemistry and can lay down a monolayer in under a second,' Moffat says, 'so from an engineering perspective it's much simpler.'"

Sputtering of PET
From MaterialsViews.com, December 28, 2012, by Margarete Halle:
"A research team have mimicked the etching of the polymer polyethyleneterephthalate (PET) in a plasma in a particle beam experiment by exposing spin-coated PET samples to quantified fluxes of argon ions and oxygen atoms.

They analyized their PET thin films using real time in-situ Fourier transform infrared spectroscopy (FTIR). After the onset of the exposure of PET to the argon ion beam, the etch rate was found to be very high, but it decreased rapidly by one order of magnitude afterwards irrespective of the ion energy."

Double-Strength Glass may be within Reach
From Rice University, September 20, 2012, by Mike Williams:  Rice University researchers have determined in a new study that the CVD process, "which is used industrially to make thin films, could yield a glass that withstands tremendous stress without breaking." It would be possible, "in principle, to get glass with at least twice the intrinsic strength of current glasses."

"Their calculations were based on a modified version of a groundbreaking Glass Rice University mathematical model they first created to answer a decades-old conundrum about how glass forms. With the modifications, theory can now predict the ultimate strength of any glass, including the common varieties made from silica and more exotic types made of polymers and metals."

Results are reported in the 
Proceedings of the National Academy of Sciences.

Thermoelectric: Controlling Heat Flow through a Nanostructure
From MIT, November 15,2012, by David Chandler:   "Thermoelectric devices, which can harness temperature differences to produce electricity, might be made more efficient thanks to new research on heat propagation through structures called superlattices. The new findings show, unexpectedly, that heat can travel like waves, rather than particles, through these nanostructures: materials made up of layers only a few billionths of a meter in thickness.

MIT Jandl and Luckyanova
This opens the possibility of new materials in which the flow of heat could be precisely tailored - materials that could have important applications.

The study involves a nanostructured material called a superlattice: in this case, a stack of alternating thin layers of gallium arsenide and aluminum arsenide, each deposited in turn through a process called metal-organic chemical vapor deposition.  The resulting layers were just 12 nanometers thick - about the thickness of a DNA molecule - and the entire structures ranged in thickness from 24 to 216 nanometers."

Mechanical Behavior of Emerging Materials
From Materials Today, November 25, 2012, by Challapalli Suryanarayana: "Nanocrystalline and glassy materials, especially the bulk metallic glasses are of relatively recent origin and exhibit high strength, but lack sufficient plasticity. A clear understanding of the mechanical behavior of these novel materials is essential before these can be seriously considered for structural applications. A great deal of research has been conducted over the past couple of decades and a vast amount of data has been generated. Here, results on strength, ductility, and deformation behavior of these novel materials have been reviewed."

Scientists Design New Lens with Dual Function Set to Revolutionize Optical Devices
From University of Birmingham (UK), November 13, 2012: "Scientists at the University of Birmingham have designed a lens using metamaterials that can function as a convex or a concave lens, according to research published today (13 November 2012) in the journal Nature Communications. By fabricating gold nano-rods on the glass, this new lens can magnify or demagnify objects, just by switching the polarisation of the light source."

"This new lens is 40 nm thin on a flat glass surface. In order to create a dual function lens, which can be switched from convex to concave, the researchers have developed an array of gold nano-structures, which is placed on top of the glass, which enables them to control the propagation of light. Then, by changing the helicity (left or right handed rotation of the electric field) of the light shining through the lens, the same lens can function as a concave or convex lens."

Clone Carbon Nanotubes in Predefined Structures
From University of Southern California, November 14, 2012:  "Scientists and industry experts have long speculated that carbon nanotube transistors would one day replace their silicon predecessors. A key reason carbon nanotubes are not in your computer right now is that they are difficult to manufacture in a predictable way. Scientists have had a difficult time controlling the manufacture of nanotubes to the correct diameter, type and ultimately chirality, factors that control nanotubes' electrical and mechanical properties. USC Nanotube

A team led by Professor Chongwu Zhou of the USC Viterbi School of Engineering and Ming Zheng of the National Institute of Standards and Technology in Maryland solved the problem by inventing a system that consistently produces carbon nanotubes of a predictable diameter and chirality"
