Nano-Texture For a Wear-Resistant and Near-Frictionless Diamond-Like Carbon

From Materials Today,
December 4, 2014,
by Ala' A. Al-Azizi et al.

 

"Penn State University and Argonne National Laboratory researchers have studied the effect of nanoscale surface texture on the wear resistance of diamond-like carbon (DLC) films. They deposited "1 μm thick DLC films onto silicon substrates pre-textured with pyramidal wells and polystyrene spheres." Researchers used a reciprocating ball-on-flat tribometer to study the nanoscale surface roughness in dry, humid and dry environments. The function and wear behavior of flat and nano-textured DLC films were tested. Nano-texturing of the surface significantly reduced the wear of DLC films but did not affect the friction coefficient in dry and humid nitrogen environments."

Silicon Nanomembranes as a Means to Evaluate Stress Evolution in Deposited Thin Films

From Extreme Mechanics Letters, December 5, 2014 by Anna M. Clausen, et al.

"Thin-film deposition on ultra-thin substrates poses unique challenges because of the potential for a dynamic response to the film stress during deposition. While theoretical studies have investigated film stress related changes in the substrate, little has been done to learn how stress might evolve in a film growing on a compliant substrate. Researchers use silicon nanomembranes (SiNMs), extremely thin sheets of single-crystalline Si, as a substrate for the growth of amorphous SiNxx to begin to address this question. Nanomembranes are released from a silicon-on-insulator wafer with selective etching, transferred over a hole etched into a Si wafer, and bonded to the edges of the hole. The nanomembrane window provides the substrate for SiNxx deposition and a platform, using Raman spectroscopy, for measurements of the evolving strain in the nanomembrane. From the strain in the nanomembrane, the film stress can be inferred from the required balance of forces in the film/substrate system. We observe that the strain in the tethered NM increases as the NM is made thinner while the intrinsic steady-state stress in the deposited film is reduced."

Researchers Develop Efficient Method to Produce Nanoporous Metals

From Lawrence Livermore National Laboratory, November 25, 2014,
by Kenneth Ma

 

"Nanoporous metals - foam-like materials that have some degree of air vacuum in their structure - have a wide range of applications because of their superior qualities.

They possess a high surface area for better electron transfer, which can lead to the improved performance of an electrode in an electric double capacitor or battery. Nanoporous metals offer an increased number of available sites for the adsorption of analytes, a highly desirable feature for sensors.

Lawrence Livermore National Laboratory (LLNL) and the Swiss Federal Institute of Technology (ETH) researchers have developed a cost-effective and more efficient way to manufacture nanoporous metals over many scales, from nanoscale to macroscale, which is visible to the naked eye.


The process begins with a four-inch silicon wafer. A coating of metal is added and sputtered across the wafer. Gold, silver and aluminum were used for this research project. However, the manufacturing process is not limited to these metals.

Next, a mixture of two polymers is added to the metal substrate to create patterns, a process known as diblock copolymer lithography (BCP). The pattern is transformed in a single polymer mask with nanometer-size features. Last, a technique known as anisotropic ion beam milling (IBM) is used to etch through the mask to make an array of holes, creating the nanoporous metal."

Air-Stable Hybrid LEDs Prepared on Flexible Substrates

From SPIE, December 9, 2014 
by Eugenia Martinez-Ferrero, CETEMMSA Technological Centre Mataró, Spain
 

 

"Solid-state lighting (SSL) devices can be made of inorganic and/or organic materials. Organic LEDs (OLEDs) are made of multilayered submicrometric stacks where each layer has a different function, such as charge transport or electroluminescence.

The organic matter and especially the materials employed for the cathodes are sensitive to moisture and oxygen. Therefore, the devices need high-performance encapsulation and must be processed under inert conditions.

Hybrid LEDs (HyLEDs) combine robust transition metal oxides with the organic active layer in devices that can be processed under air and do not require encapsulation. The diodes work with an inverted injection scheme that permits the application of inert metals as counterelectrodes. The structure is formed by a semiconducting transparent electrode, typically ITO (indium-doped tin oxide), an electron transport layer (ETL) made of transition metal oxides, the organic active layer, an inorganic hole transport layer, and the metallic electrode

Unlocking the Potential of Graphenes - Functionalization via Plasma 

From Nanowerk Spotlight,
December 4, 2014, by
Dr. Martin Kemp (Haydale)
 

"Graphene is inherently inert, making it very difficult to disperse within a target material. Modifying the surface chemistry of graphenes has been identified only relatively recently as a key factor in realizing the full potential of nanomaterials. Incorporating nanomaterials into polymeric and liquid phase applications requires a homogenous dispersion within the secondary phase. This is a difficult task, given the natural tendency of nanomaterials to agglomerate or separate out means that good dispersions can only be attained by engineering the surface of the materials via a functionalization process.

Functionalization can be achieved by wet chemistry involving strong acids. Although these processes are scalable, they utilize aggressive chemicals with an associated waste stream issue and tend to create defects in the material structure and introduce impurities.

The alternative functionalization route, avoiding wet chemistry whilst providing a highly tailored material for both raw material producers and application manufacturers, is via a plasma functionalization process.

The patent-pending process, which has been developed to overcome the key barrier to commercialization, utilizes a low temperature (under 100°C), low pressure gas plasma within a rotating drum containing the nanomaterials selected for functionalization. The ability to control gas and vapour mixtures allow for customized functionalization of a specifically selected nanomaterial, which addresses the issues of graphene's complexity by enabling a customized solution to be provided for specific applications."

UCLA Engineers Create 'Superomniphobic' Texture Capable of Repelling All Liquids
 

From UCLA, November 27, 2014, 
by Matthew Chin
 
"A pair of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created the first surface texture that can repel all liquids, no matter what material the surface is made of.

Because its design relies only on the physical attributes of the texture, the texture could have industrial or biomedical applications. For example, the surface could slow corrosion and extend the life of parts in chemical and power plants, solar cells or cookware.

Researchers demonstrated for the first time true omniphobicity. The engineers formed a surface covered with thousands of microscale flathead nails, each about 20 micrometers in head diameter - each much smaller than the width of a typical human hair - resembling the appearance of existing superoleophobic textures. The key to the team's innovative design is additional nanoscale details around the nail heads..

The surface super-repelled all available liquids, including water, oils and many solvents, qualifying to be superomniphobic. It even super-repelled a fluorinated solvent called perfluorohexane, the liquid with the lowest known surface tension."

Theory Details How 'Hot' Monomers Affect Thin-Film Formation
 

From Rice University, 
December 10, 2014, by Mike Williams
 
"Like a baseball player sliding into third, a hot monomer skids in a straight line along a cold surface until it's safely among its fellow molecules.

This is not what usually happens when scientists assemble monomers to make thin films for next-generation electronics, but the details remained a puzzle until a team led by Rice University got involved. Monomers are organic molecules that, in this application, form clusters and eventually complete layers.

Researchers at Rice and the University of Maryland led by Rice theoretical physicist Alberto Pimpinelli devised the first detailed model to quantify what they believe was the last unknown characteristic of film formation through deposition by vacuum sublimation and chemical vapor deposition. The mathematical model predicts how "hot" monomers on cold substrates affect the growth of thin films being developed for next-generation electronics.

New World Record for Solar Cell Efficiency at 46%


From Soitec, December 1, 2014

 

"A new world record for the direct conversion of sunlight into electricity has been established. The record multi-junction solar cell converts 46 % of the solar light into electrical energy and was developed by Soitec and CEA-Leti, France, together with the Fraunhofer Institute for Solar Energy Systems ISE, Germany. Multi-junction cells are used in concentrator photovoltaic (CPV) systems to produce low-cost electricity in photovoltaic power plants, in regions with a large amount of direct solar radiation.

A special challenge that had to be met by this cell is the exact distribution of the photons among the four sub-cells. This has been achieved by precise tuning of the composition and thicknesses of each layer inside the cell structure."

The Finer Details of Rust

From Vienna University of Technology, December 5, 2014, by Florian Aigner
 

Magnetite (or Fe3O4) is an elaborate kind of rust - a regular lattice of oxygen and iron atoms. But this material plays an increasingly important role as a catalyst, in electronic devices and in medical applications.
 

Perhaps the most surprising property of the magnetite surface is that single atoms placed on the surface, for instance gold or palladium, stay perfectly in place instead of balling up and forming a nanoparticle. This effect makes the surface an extremely efficient catalyst for chemical reactions - but nobody had ever been able to tell why magnetite behaves that way.
 

Scientists at the Vienna University of Technology have now shown that the atomic structure of the magnetite surface, which everybody had assumed to be well-established, has in fact been wrong all along. The properties of magnetite are governed by missing iron atoms in the sub-surface layer. "It turns out that the surface of Fe3O4 is not Fe3O4 at all, but rather Fe11O16", says Professor Ulrike Diebold, head of the metal-oxide-research group at TU Wien (Vienna)."

Light Propagation in Solar Cells Made Visible

 
From EurekAlert!, December 5, 2014, Forschungszentrum Jülich 

"How can light which has been captured in a solar cell be examined in experiments? Jülich scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

Until recently, light trapping within periodically nanostructured solar cells could only be analyzed using indirect methods, as captured light is not visible from outside of the solar cell. However, the quantum mechanical tunneling effect of light allows it to be tracked if a light-conducting component is brought extremely close to the cell's surface. Through use of a glass fiber tip, the researchers were able to measure the amount of light that had actually been captured in the solar cell using a method called near-field optical microscopy."

Nanoparticle Network Could Bring Fast-Charging Batteries

From Purdue University, 
December 3, 2014, by Emil Venere

"A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.

The researchers have performed experiments with a "porous interconnected" tin-oxide based anode, which has nearly twice the theoretical charging capacity of graphite. The researchers demonstrated that the experimental anode can be charged in 30 minutes and still have a capacity of 430 milliamp hours per gram (mAh g−1), which is greater than the theoretical maximum capacity for graphite when charged slowly over 10 hours.

The anode consists of an "ordered network" of interconnected tin oxide nanoparticles that would be practical for commercial manufacture because they are synthesized by adding the tin alkoxide precursor into boiling water followed by heat treatment."
