Art13 Zinc Oxide Nanostructures for Optoelectronic and Energy Devices
From SPIE Newsroom (DOI: 10.1117/2.1201312.005270), January 09, 2014, by Yeong Hwan Ko, Soo Hyun Lee and Jae Su Yu

"Zinc oxide (ZnO), indium tin oxide (ITO), and titanium dioxide (TiO2) have wide bandgaps and are highly effective materials for electronic/optoelectronic and chemical device applications. The oxides are characterized by low-dimensional nanostructures and architectures, including nanorod arrays (NRAs), submicrorod arrays (SMRAs), and cone-shaped subwavelength nanostructure arrays (SNAs). These features exhibit superior optical and morphological properties not observed in bulk materials, due to quantum size effects. Such nanostructures have potential for high-performance novel electronic and optoelectronic devices."

Art10 Minimizing Risks
From SCHOTT Solutions Technology Magazine, No. 2/2013, by Alexander Lopez

"The problem of delamination, which is the peeling of inorganic flakes from the inner glass surface of a pharmaceutical vial as a result of interaction with its contents, remains a top priority issue for the pharmaceutical industry. This phenomenon has already caused numerous recalls that can each cost several million dollars. The US drug authority is thus explicitly requiring that pharmaceutical companies manage their risks more closely. SCHOTT® Vials DC (DC = delamination controlled) offer pharmaceutical companies a new way to lower the risk of delamination by providing an improved packaging product."

Touch Panel Design 
Electronic Products, January 2014, by Tony Gray: 

"As projected capacitive touch panels continue to expand product offerings in consumer and industrial markets, designers need to become familiar with the trade-offs involved when designing-in a projected capacitive touch panel. There are details to be considered, such as alternative materials that can be used for constructing a projected capacitive touch panel, the characteristics of those materials, and the functional trade-offs involved.


Cover lenses - When specifying a cover lens, potential characteristics that drive the material choice include hardness, impact strength and safety. Another consideration when choosing a cover lens material is the dielectric. Cover lenses can also be enhanced with films and/or coatings, including anti-glare (AG), anti-reflective (AR), anti-smudge, etc.


Adhesive - Depending on the touch panel design and whether or not the touch panel is being bonded to a TFT, the entire stack-up may include three separate adhesive layers. One of the biggest concerns when choosing an adhesive is birefringence. Another factor is the temperature range of the adhesives being used. Some adhesives can stretch, which allows air bubbles to form if the temperature gets too high."

Art4 Methods for Imaging Samples in Reactive Environments 
From Chemical and Engineering News, January 06, 2014, by Mitch Jacoby 

"Scientists gathered at Materials Research Society meeting in Boston to discuss the latest advances in TEM methods for analyzing technologically important materials under conditions that not long ago would have been nearly impossible. Examples included solid catalysts exposed to high pressures of reactive gases at elevated temperatures, and electrodes or other solids in contact with liquids. Those conditions are par for the course in chemical reactors and batteries, respectively. But historically they were off-limits to electron microscopes, which were designed to operate at high vacuum and room temperature. Flooding a microscope with any gas, especially a reactive one, and heating were sure ways to ruin the instrument.

Stain-Free, Self-Cleaning Clothing on the Horizon 
From Wyss Institute, January 2014

"The team from Harvard's Wyss Institute and the School of Engineering and Applied Sciences (SEAS) has demonstrated the uncanny ability of SLIPS (Slippery Liquid-Infused Porous Surfaces) - inspired by the pitcher plant - to repel nearly any material it contacts: water, ice, oil, saltwater, wax, blood, and more. They have demonstrated its versatility under extreme conditions of pH and temperature, and have successfully used SLIPS to coat everything from refrigeration coils to lenses, windows, and ceramics.


And now, the team has modified everyday cotton and polyester fabrics to exhibit traditional antifouling SLIPS behavior. The SLIPS coating anchors a slippery lubricated film infused to a nano-porous solid surface, creating a material that performs exceedingly well under pressure or physical damage, and can resist all kinds of liquids, including oil. The advance could meet the need for a robust, stain-resistant textile for a host of consumer and industrial applications."

Art3Nanotechnology Primer: Graphene - Properties, Uses and Applications
From Nanowerk Spotlight, January 29, 2014 by Michael Berger/span>

"Graphene is undoubtedly emerging as one of the most promising nanomaterials because of its unique combination of superb properties, which opens a way for its exploitation in a wide spectrum of applications ranging from electronics to optics, sensors, and biodevices. 

Currently, the most common techniques available for the production of graphene include micromechanical cleavage, CVD, epitaxial growth on SiC substrates, chemical reduction of exfoliated graphene oxide, liquid phase exfoliation of graphite and unzipping of carbon nanotubes. However, each of these methods can has its own advantages as well as limitations depending on its target application. In order to surmount these barriers in commercializing graphene, concerted efforts are being made by researchers throughout the world."

Art6Diamond Film Possible Without the Pressure
From From Rice University, February 03, 2014, by Mike Williams 

"Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems. Scientists have speculated about it and a few labs have even seen signs of what they call diamane, an extremely thin film of diamond that has all of diamond's superior semiconducting and thermal properties. 

"Now researchers at Rice University and in Russia have calculated a "phase diagram" for the creation of diamane. The diagram is a road map. It lays out the conditions - temperature, pressure and other factors - that would be necessary to turn stacked sheets of graphene into a diamond lattice."

Art7 Activating Titanium Dioxide with Visible Light
From Chemical and Engineering News, January 13, 2014 

"Many scientists view titanium dioxide as an attractive, low-cost photocatalyst for a variety of applications, including water purification, water splitting, and solar power. But there is a complication: The material catalyzes reactions mainly in response to ultraviolet light. Now, researchers at the Institute of Materials Research & Engineering in Singapore have found a way to dope the surface of TiO2 with nitrogen so that the material responds to visible light, drastically increasing its photocatalytic activity."

Art8 Nanoscale Engineering Boosts Performance of Quantum Dot Light Emitting Diodes
From Los Almos National Laboratory, October 2013 

" Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions.


Making the light at the end of the tunnel more efficient


LOS ALAMOS, N.M., Oct. 25, 2013-Dramatic advances in the field of quantum dot light emitting diodes (QD-LEDs) could come from recent work by the Nanotechnology and Advanced Spectroscopy team at Los Alamos National Laboratory.


Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions. They feature near-unity emission quantum yields and narrow emission bands, which result in excellent color purity. The new research aims to improve QD-LEDs by using a new generation of engineered quantum dots tailored specifically to have reduced wasteful charge-carrier interactions that compete with the production of light.

Art9 Phonon Map Offers Direction for Engineering New Thermoelectric Devices
From Oak Ridge National Laboratory, January 08, 2014, by Katie Jones 

"Automobiles, power plants, laptops, and many other machines produce heat when they operate. Waste heat is an unavoidable energy loss, a trade-off in order to produce the kind of energy for which the machine is intended. However, this heat could be partly recycled into electrical energy through thermoelectric technology, which converts a temperature difference into an electric voltage.

Art11A Deeper Look at Interfaces 
From the Lawrence Berkeley Lab, January 14, 2014, by Lynn Yarris 

"In today's burgeoning world of nanotechnology, the interfaces between layers of metal oxides are becoming increasingly prominent, with applications in such high-tech favorites as spintronics, high-temperature superconductors, ferroelectrics and multiferroics. Realizing the vast potential of these metal oxide interfaces, especially those buried in subsurface layers, will require detailed knowledge of their electronic structure."

Art15 Extraordinary Photoresponse in Two-Dimensional In2Se3Nanosheets
From ACS Nano (Vol. 8, No. 1 DOI: 10.1021/nn405037s), December 21, 2014 by Robin B. Jacobs-Gedrim, Mariyappan Shanmugam , Nikhil Jain , Christopher A. Durcan , Michael T. Murphy, Thomas M. Murray , Richard J. Matyi , Richard L. Moore , II, and Bin Yu

""Researchers at SUNY College of Nanoscale Science and Engineering have demonstrated extraordinary photoconductive behavior in two-dimensional (2D) crystalline indium selenide (In2Se3) nanosheets. Ultrathin (few quintuple layers), highly crystalline In2Se3 nanosheets were prepared by micromechanical exfoliation. Photocurrent measurements reveal that semiconducting In2Se3 nanosheets have an extremely high response to visible light. The key figures-of-merit exceed that of graphene and other 2D material-based photodetectors reported to date. In addition, the photodetector has a fast response time of
1.8 × 10-2s."

Art15 Researchers Model Macroscale Plasmonic Convection to Control Fluid and Particle Motion
From University of Illinois, January 21, 2014

"Researchers at University of Illinois have developed a new theoretical model that explains macroscale fluid convection induced by plasmonic (metal) nanostructures. Their model demonstrates the experimentally observed convection velocities of the order of micrometers per second for an array of gold bowtie nanoantennas (BNAs) coupled to an optically absorptive ITO substrate.


The development of the model led the researchers to several important conclusions. It allowed them to understand the high-velocity particle motion observed in experiments with plasmonic tweezers, and they realized that inclusion of an ITO layer is critical in distributing the thermal energy created by the BNAs-a fact that has previously been overlooked. Additionally, they found that the ITO alone could be used as a simple, alternative route to achieving fluid convection in lab-on-a-chip environments. The researchers also observed that the plasmonic array alters absorption in the ITO, causing a deviation from Beer-Lambert absorption."

Art15 Researchers Report Revolutionary Technique to Prepare Nanowires
From Nanowerk Spotlight, February 04, 2014, by Michael Berger

"Over the years, researchers have developed a large number of techniques to synthesize nanowires and nanotubes in the laboratory. These procedures vary widely in their hardware requirements and methodology. Nevertheless, they all share a set of common goals: simplicity of protocol; fast execution; and low energy input.


A group of scientists at Sungkyunkwan University in South Korea has reported a breakthrough in all three of these areas, leading to a revolutionary and remarkably simple technique for preparing one-dimensional nanostructures. The group demonstrates a unique approach to growing amorphous boron nanowires coated with a thin oxide layer through careful management of the electron beam in a transmission electron microscope (TEM) as it irradiates an amorphous boron oxide matrix embedded with gold nanoparticles."
