Edges Ease Surface Oxidation of Metals 
From Chemical & Engineering News, December 17, 2012, by Jyllian Kemsley: "Oxidation of metal surfaces preferentially occurs when metal atoms detach form defect edges and react with adsorbed oxygen atoms. By using transmission electron microscopy to study oxidation of copper surfaces under low-pressure oxygen, a research group at the State University of New York, Binghamton, determined that oxidation occurs Rust and Dirtas oxygen adsorbs onto the surface and reacts with copper atoms that detach from step edges and diffuse across the surface. The team found that oxidizing a flat surface leads to more stress and mechanical breakdown between the metal and oxide layers, while step-facilitated oxidation reduces stress and smooths the surface as metal atoms are drawn from the edges."

Novel Approaches to Thermal Spray
From Advanced Materials & Processes, November/December 2012, by Rajan Bamola: "New thermal spray methods to apply functional oxide coatings have been developed. Many require crossover technology like chemical or physical vapor deposition (CVD or PVD). The most well-known cross-over technology in thermal spray is Sulzer Metco's (Switzerland) very low pressure plasma spray (VLPPS), also referred to as plasma spray PVD. PVD thermal barrier coatings have better strain tolerance compared with air plasma spray (APS) coatings. Besides gas turbine applications, researchers are investigating VLPPS coatings for solid fuel cells, biomedical components, and electronics. Thin-film transparent yttriathermal spray CVD is of particular interest in semiconductor field where dense, well-adhering thin films of special oxides such as yttria are of interest for plasma erosion resistance and corrosion resistance against halogen attack."

Deformable Mirrors Enable a Leap Forward in X-Ray Telescope Performance 
From SPIE Newsroom, January 7, 2013, by Vincenzo Cotroneo: "Space-based x-ray telescopes allow astronomers to study a wide range of energetic phenomena from neutron stars to diffuse million-degree gas permeating galaxy clusters. Unfortunately, x-rays are notoriously difficult to focus. To produce images, x-ray telescopes must use grazing incidence mirrors, which reflect incoming photons at very shallow angles. High-resolution x-ray mirrors usually use the Wolter Type I geometry-a double reflection off first a parabolic and then a hyperbolic surface. As a consequence of the shallow angles (typically 1° or less), the collecting area is a small fraction of the mirror surface. To increase the telescope's effective area, multiple mirror pairs are nested. Thin mirrors can be nested in higher number and more densely than thicker Mirror Elementsmirrors, resulting in a large total collecting area, but they are more subject to manufacturing and mounting errors that degrade the angular resolution."

Peel and Stick Solar Panels 
From Stanford University, December 19, 2012, by Glen Martin:
"Stanford researchers have succeeded in developing the world's first peel-and-stick thin-film solar cells. Unlike standard thin-film solar cells, peel-and-stick thin-film solar cells do not require any direct fabrication on the final carrier substrate. This is a far more dramatic development than it may initially seem. All the challenges associated with putting solar cells on unconventional materials are avoided with the new process, vastly expanding the potential applications of solar technology.
Stanford Peel and Stick Solar Panels

Nonconventional or 'universal' substrates are difficult to use for photovoltaics because they typically have irregular surfaces and they don't do well with the thermal and chemical processing necessary to produce today's solar cells. Stanford researchers got around these problems by developing this peel-and-stick process, which gives thin-film solar cells flexibility and attachment potential we've never seen before, and also reduces their general cost and weight. They didn't lose any of the original cell efficiency."

Ultra-Thin Coatings Change Color with Few Atoms Difference in Thickness
From Harvard University, October 2012, by Caroline Perry: "Harvard physicists have discovered that very "lossy" thin films, if atomically thin, can be tailored to reflect a particular range of dramatic and vivid colors. The structure made of only two elements, gold and Harvard Physics as Artgermanium (or many other possible pairings), can be whatever color one chooses. The germanium film is applied through standard manufacturing techniques-lithography and physical vapor deposition, so with only a minimal amount of material (a thickness between 5 and 20 nanometers), elaborate colored designs can easily be patterned onto any surface, large or small."

The work is published in the journal Nature Materials (online).

Electrodynamic Dust Shield on the International Space Station
From NASA, Kennedy Space Center, December 2012, by C.I. Calle:
Electrodynamic Dust Shields (EDS) have been in development at NASA as a dust mitigation method for lunar and Martian missions. Dust mitigation technologies are high on list of requirements for these planetary bodies, since they covered with layers of dust that can interfere with the operation of equipment, rovers, habitats spacesuits, and resource processing plants. They report on the development of a flight experiment to fully expose four EDS panels to the space environment.

The EDS uses traveling electric fields to transport electrostatically charged particles along surfaces. To generate the traveling electric fields, the EDS consists of a multilayer dielectric coating with an embedded thin electrode grid running a multiphase low frequency AC signal. Electrically charged particles are carried along by the traveling field due to action of coulomb and dielectrophoretic forces.

The EDS multilayer coating is applied to metallic and electrically insulating surfaces. EDS with vapor-deposited metallic electrodes are used for metallic surfaces, such as astronaut helmets. For optical systems, transparent, vapor-deposited ITO electrodes are used."

Production and Processing of Graphene and 2D Crystals
From Materials Today, December 2012 by Francesco Bonaccorso:
New applications for graphene require development of reliable and inexpensive commercial manufacturing processes. This article reviews current graphene processes for preparation, manufacturing, and handling. Manufacturing processes include CVD, MBE, and ALE (atomic layer epitaxy). Other 2d crystals and hybrids have similar properties to graphene. In addition to utilizing graphene's manufacturing processes, 2d crystal thin films are produced by PVD and magnetron sputtering.

Carbon Nanotubes Used for Electronic Interconnects
From Georgia Institute of Technology, October 2012, by John Toon:
"Using a new method for precisely controlling the deposition of carbon, researchers at Georgia Institute of Technology have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques. Based on electron beam-induced deposition (EBID), the work is believed to be the first to connect multiple shells of a multi-walled carbon nanotube to metal terminals on a semiconducting substrate, which is relevant to integrated circuit fabrication. Using this three-dimensional fabrication technique, researchers developed graphitic nanojoints on both ends of the multi-walled carbon nanotubes, which yielded a 10-fold decrease in resistivity in its connection to metal junctions. 

Silicon Substrate The research was supported by the Semiconductor Research Corporation, and in its early stages, by the National Science Foundation. The work was reported online in the journal IEEE Transactions on Nanotechnology."

How Transparent is Graphene?
From MIT News, December 4, 2012, by David L. Chandler: "
The "transparency" of a graphene coating to wetting is not as absolute as some researchers had thought. New research at MIT shows that for materials with intermediate wettability, graphene does preserve the properties of the underlying material. But for more extreme cases, superhydrophobic or superhydrophilic surfaces, an added layer of graphene does significantly change the way coated materials behave. Most electrically conductive materials are hydrophilic. On the other hand, for many electronic and military applications, it is important to fabricate hydrophobic, electrically conductive surfaces. And while graphene's transparency to wettability is not perfect, it may still be good enough for such applications. 

Water on Graphene This research shows that by depositing a large graphene sheet, grown by CVD process, on another material's surface, it would be possible to induce electrical conductivity on the surface, while partially preserving the desired surface wetting behavior. They have demonstrated that the wettability of a transparent, graphene-coated surface can be manipulated without undermining its thermal/electrical conductivity."

Stretchable Electronics and Electrics for Electric Vehicles
From IDTechEx, December 28, 2012, by Dr. Peter Harrop: "This article shares some of the research in the newly updated IDTechEx report, "Stretchable Electronics Comes to Market". Flexible electronics is typically printed reel to reel and it is typically rollable around a 2.5 centimeter diameter, newer versions in the laboratory being rollable around a human hair.Smart Surface

However, this flexible electronics is barely stretchable and its flexibility is usually only in one dimension at a time. In the automotive industry and particularly with electric vehicles for land, water and air, something more is preferable - three dimensional stretchability. It is needed both for producing rigid products by stretching them to form during plastic molding and it is useful in a form that is stretchable in use."

Stretchable Energy Storage Devices
From University of Delaware, December 11, 2012, by Karen B. Roberts:
"According to the University of Delaware's Bingqing Wei, stretchable electronics are the future of mobile electronics, leading giants such as IBM, Sony and Nokia to incorporate the technology into their products. Advances in soft and stretchable substrates and elastomeric materials have given rise to an entirely new field. Rechargeable and stretchable energy storage devices, also known as supercapacitors, are urgently needed to complement advances currently being made in flexible electronics.  

Flexible Energy Source The research group at the University is making significant progress in developing scalable, stretchable power sources for this type of application using carbon nanotube macrofilms, polyurethane membranes and organic electrolytes. To reveal a stretchable supercapacitator's true performance, the Wei group examined the system's electrochemical behavior using buckled single-wall nanotube (SWNT) electrodes and an elastomeric separator. The supercapacitor developed in his lab achieved excellent stability in testing."
