Graphene Electrode Defects Alter Electrode-Electrolyte Interface Behavior 
From Pacific Northwest National Laboratory, February 2014 

Graphene, a single layer of carbon atoms, is an attractive electrode material for supercapacitor applications because of its high surface area.Scientists at Pacific Northwest National Laboratory (PNNL) and Princeton University investigated how the surface chemistry of graphene affects the charge storage mechanism. They found that the defects on the graphene surface alter the liquid's interaction with the surface. The ionic liquid's cations aggregate near a defect, and the anions are repelled by it, altering the molecular arrangement of the ionic liquid on the surface.


Traditional supercapacitors are made of high surface area carbon. However, graphene potentially has the highest surface area among carbon materials and, thus, could significantly increase the specific capacity. It is difficult to understand and control how the charged ionic species are incorporated and transported in the graphene electrodes. The team's research provides fundamental insights into the molecular structures built when graphene has functional groups or defects that interact with the electrolyte. The study provides scientists with a basic understanding to create better materials for energy storage."

Art13Imperceptible Electronic Skin
From Information Display, January/February 2014, by Tsuyoshi Sekitani, Martin Kaltenbrunner, Tomoyuki Yokota, and Takao Someya

"Electronic Skin (E-Skin) is a flexible, stretchable sensor array that can essentially computerize a surface, including that of robots and human beings. The ideal E-Skin is still under development, but it will be sensitive to heat and pressure and also be so light that a user or wearer is unaware of its presence. It will stretch and conform to a variety of surfaces, including over large areas. 

The research group at the University of Tokyo first developed E-Skin about a decade ago. In this article, they describe recent research in terms of progress, bottlenecks, and future prospects for electronic-device-human interfaces such as E-Skin."

Art14 Maximum Light Trapping in Solar Cells
From From Delft University of Technology (The Netherlands), February 24, 2014 by Webredactie M&C 

"Researchers at TU Delft have opened the way for the realization of the next generation of high-efficiency, cost-effective and ultra-thin crystalline silicon solar cells. They are the first in the world to come very close (99.8%) to the theoretical limit of absorption enhancement (light trapping) in a broad light spectrum range. An experimental demonstration of this absorption enhancement limit in solar cells has been elusive for the last thirty years."

Art10 Physicists Solve 20-Year-Old Debate Surrounding Glassy Surfaces
From From University of Waterloo (Canada), February 28, 2014

"University of Waterloo physicists have succeeded in measuring how the surfaces of glassy materials flow like a liquid, even when they should be solid. Understanding the mobility of glassy surfaces has implications for the design and manufacture of thin-film coatings and also sets practical limits on how small we can make nanoscale devices and circuitry."

Art2  Smart Glass - Could Antireflective Self-Cleaning Windows Increase the Efficiency of Solar Cells? 
From University of Cambridge (U.K.), February 21, 2014: 

"Porous films, which use similar properties to those seen in moth eyes in combination with nanoparticles, are being developed into robust, self-cleaning antireflective coatings for use on both plastic and glass.Details of the coatings, which were developed by researchers at the University of Cambridge, were recently outlined in the journal Nano Letters.


Antireflective coatings need to reflect as little light as possible in order to be effective, but it is extremely difficult to produce them as a single layer. The antireflective properties of moth eyes come not from a single layer, but from a hexagonal pattern of tiny bumps. The spaces between these bumps are so small that incoming beams of light see the eye's surface as a single layer, essentially removing the interface between the air and the surface, allowing moths to see at night and be less visible to predators.The problem with synthetic versions of moth eye coatings is that the tiny spaces which make the coating antireflective in the first place can very quickly become clogged with dirt, which causes the antireflective effect to be lost."

Researchers Produce First Ever Atom-by-Atom Simulation of ALD Nanoscale Film Growth 
FromTyndall National Institute (Ireland), February 05, 2014

"Researchers at Tyndall National Institute, Ireland, have produced the first ever atom-by-atom simulation of nanoscale film growth by ALD.Growth simulations could help to improve the ALD process, but until now, were not accurate enough over experimental timescales.


While quantum mechanical simulations give an accurate atom-by-atom picture of individual ALD reactions at the tiniest scales, this is still much shorter from what can be measured in the lab. The Tyndall group led by Dr. Simon Elliott has for the first time combined the accuracy from the quantum mechanical level with the statistics needed to follow how thousands of atoms react millions of times a second, building up layers of material, as in the lab."

Art3Ultra-Flexible OTFT Device Array Suitable for Foldable AMOLED Displays
From Centre for Process Innovation (U.K.), February 11, 2014

"The Centre for Process Innovation (CPI) has developed novel backplane fabrication processes to allow the bending of Organic Thin Film Transistors (OTFT) arrays to small radii (1 mm) without a significant reduction in device performance. The work undertaken demonstrates progress towards optimum Organic Semiconductor (OSC)/OTFT processing and performance to enable their integration into ultra-flexible active matrix organic light emitting diode AMOLED backplanes. High performance OSC materials with charge mobility suitable for OLED driving were used in the tests on 50 micron thick PEN film."

Art6The Core of Corrosion
From Argonne National Laboratory, February 14, 2014, by Jared Sagoff 

"One of the world's most common and costly chemical reactions, corrosion happens frequently at the boundaries between water and metal surfaces. In the past, the process of corrosion has mostly been studied from the metal side. 


However, in a new study, scientists at the Center for Nanoscale Materials at the U.S. Department of Energy's Argonne National Laboratory investigated the problem from the other side, looking at the dynamics of water containing dissolved ions located in the regions near a metal surface."

Art7 Thin-Film PV is as Simple as ABCD
From NPD Solarbuzz, February 13, 2014, by Finlay Colvile 

"Here is what's happening in thin-film PV now. Gone are the legacy thin-film market segments made purely by technology type. All manufacturers of thin-film solar panels now fit into four groupings:  

  1. Any thin-film (e.g. CIGS, CdTe) manufacturer with proven volume capability. Their business encompasses R&D, production, sales and marketing. The leaders are First Solar, Solar Frontier, Sharp and 3Sun each with technologies chosen over 10 years ago. 
  2. a-Si manufacturers located in either China or Taiwan. 
  3. a-Si manufacturers located mostly in Southeast Asia and Japan. 
  4. Other thin-film manufacturers, including organics.

Art8 Researchers Characterize Graphene's Bonding Effect on Platinum Nanoparticles
From University of Arkansas, February 24, 2014 



"An international team of scientists, led by a research group at the University of Arkansas have found that platinum nanoparticles limit their size and organize into specific patterns when bonded to freestanding graphene.


While displaying this behavior, the bonded platinum nanoparticles maintain an effective surface area functioning as a catalyst for chemical reactions, a discovery that could lower the production costs of platinum-catalyzed fuel cells."

Art15 Researchers Develop Ultrathin Perfect UV Light Absorber
From Helmholtz-Zentrum Geesthacht (Germany), February 27, 2014

"UVlight has not only harmful effects on molecules and biological tissue like human skin but it also can impair the performance of organic solar cells upon long-term exposure. Researchers of Kiel University and Helmholtz-ZentrumGeesthacht have now developed a so-called plasmonic metamaterial, which is compatible with solar technology and completely absorbs UV light - despite being only 20 nanometers thin.It is one of the first metamaterial perfect absorbers designed for such high frequency.


Metamaterials are artificial materials composed of designed unit cells which can show striking and unique electromagnetic properties not inherent in the individual constituent components."
