President Obama Launches Competition for New Textiles-Focused Manufacturing Innovation Institute; New White House Supply Chain Innovation Initiative; and Funding to Support Small Manufacturers
In Cleveland, Ohio, the President launches ninth manufacturing hub competition and announces measures to strengthen the small manufacturers that power America’s supply chains.

WASHINGTON, DC  – Today the President is announcing nearly $500 million in public-private investment to strengthen American manufacturing by investing in cutting-edge technologies through a new, textiles-focused manufacturing institute competition led by the Department of Defense, and by sharpening the capabilities of small manufacturers through Manufacturing Extension Partnership competitions in twelve states. The White House, as detailed in a new report, is also launching a Supply Chain Innovation Initiative focused on building public-private partnerships to strengthen the small U.S. manufacturers that anchor the nation’s supply chains.

The President’s Fiscal Year 2016 Budget, to create jobs and strengthen America’s leadership in advanced manufacturing technology, provides the resources to double the number of manufacturing innovation institutes nationwide to 16 by the end of 2016 and fulfills the President’s goal of building a network of up to 45 institutes over the decade. In contrast, the House Republican Budget released yesterday entrenches the harmful sequester levels of funding and proposes to eliminate the Manufacturing Extension Partnership, putting at risk critical investments in advanced manufacturing, workforce development and training, and innovation proposed in the President’s Budget.   more     ALSO more information here

Wearable technology: a materials goldmine

By Dr Peter Harrop, Chairman, IDTechEx www.IDTechEx.com

In 2025 over $25 billion will be spent on formulations and intermediate materials for wearable technology, as forecast by analysts IDTechEx in the brand new report "Wearable Technology Materials 2015-2025". Companies at this early part of the value chain will enjoy a multiplier over the coming decade. They will participate in a rapidly growing market and they will take a greater percentage of it as some other parts of the value chain are eliminated. This is not because e-fibers will be used to create e-textiles from bandages to apparel. That is a longer term prospect. Instead, it is a matter of making today's devices differently. They need to be made smaller, flexible, more comfortable, often invisibly hidden in or under clothing or transparent. Other items in the wish list will sometimes include being implantable, disposable and a frequent request is that they should never be short of electricity. Indeed, power running out after a few hours, a common inadequacy today, can be life threatening with exoskeletons and medical e-patches and dangerous with planned glucose- indicating contact lenses and wristbands for severe diabetics.

In most cases, the only way forward is to abandon the 100 year old "components in a box" approach of almost all manufacturers of wearable technology today. Instead, we shall use structural electronics where smart materials are key. This will be a cornucopia for manufacturers of electronic and electrically functional materials that can be made into structures using those increasingly crucial intermediate materials.

However, this industry needs to prioritise and de-risk its future investments and analysts IDTechEx has now provided the tools to do this. Its report, "Wearable Technology Materials 2015-2025" finds large opportunities for organics, inorganics and composites. It tackles prioritisation in different ways. First it looks at which materials are low risk because they are useful in many different ways. For example, polyvinylidene difluoride is electrically a gymnast of chemicals. It and its derivatives can be electret microphone, ferroelectric memory, piezoelectric energy harvester and much more besides.

Then IDTechEx has looked at the prevalence of different formulations that are being used in planned integrated devices for the future. For example, there is great interest in lithium, indium and titanium salts across a broad sweep of functionality. III-V compounds feature strongly in next generation products such as flexible displays and photovoltaics for low light conditions. Carbon allotropes are very broadly researched for wearables and allied markets but there is not much on C60 buckyballs. Graphene is of more interest for future batteries, supercapacitors, flexible displays and so on.

Most of the world's leading companies making primary and intermediate materials will be using IDTechEx prioritisation tools to capture a major share of this large new market. There are also many niche opportunities for smaller players such as those specialising in the chemistry of tungsten or tantalum, where many new uses are emerging. Similarly, although fluorocarbons have large potential, there are plenty of niche opportunities for other organics and some very big ones. IDTechEx counsels that many new morphologies and formats are needed from electronic printing inks to metal feedstock for the new higher speed, lower cost 3D printing. These challenges with the new formulations identified reduce competition and open up opportunities for premium pricing.

Rice University Again:  Researchers' acid-free approach leads to strong conductive carbon threads
The single-walled carbon nanotubes in new fibers created at Rice line up like a fistful of uncooked spaghetti through a process designed by chemist Angel Martí and his colleagues.

Conductive Fibers Appear in Nature?

Stretchy Gold Electronics Could Someday Live Inside Your Brain

What looks like a shiny piece of gold foil is actually a new stretchy conductive material that could one day be fashioned into electrode implants for the brain or pacemakers for the heart. Crafted from gold nanoparticles and an elastic polymer, the material retains its conductivity even when stretched to four times its original length.“It looks like elastic gold,” said Nicholas Kotov, a chemical engineer at the University of Michigan. “But we can stretch it just like a rubber band.” When it stretches, it retains all the properties of a metal, including the ability to transport electrons.

Normally, stretching a circuit disrupts the interatomic connections that keep electrons flowing from one end to the other. Most existing stretchable electronics overcome this difficulty by using accordion- or spring-like folding wires that can expand and contract. But in the new material, no folds or convolutions are needed.   more-link

An Advance Toward Ultra-Portable Electronic Devices
Chemical Wiring and Soldering toward All-Molecule Electronic Circuitry"         Journal of the American Chemical Society
Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand. The breakthrough is a method for creating and attaching the tiny wires that will connect molecular components, reports a new study in the Journal of the American Chemical Society.
Yuji Okawa and colleagues write that the "key to single-molecule electronics is connecting functional molecules to each other using conductive nanowires. This involves two issues: how to create conductive nanowires at designated positions, and how to ensure chemical bonding between the nanowires and functional molecules." That challenge has stymied many researchers, who have struggled to produce wires small enough to use in molecular circuits.
The scientists now demonstrate a method that uses the tip of a scanning tunneling microscope to jump-start the formation of a molecule chain. The chain or "wire" spontaneously chemically bonds with other molecular components in the circuit under construction, a process that Okawa and colleagues dub "chemical soldering." The wiring method can be used to connect molecular switches, memory bits, and transistors. The scientists say their technique "will enable us to develop cheaper, higher-performance, and more ecological alternatives to conventional silicon-based devices."

MIT Finds New Way to Control Conductivity: Reversible Control of Electrical and Thermal Properties Could Find Uses in Storage Systems
"The process works because when the liquid freezes, the pressure of its forming crystal structure pushes the floating particles into closer contact, increasing their electrical and thermal conductance. When it melts, that pressure is relieved and the conductivity goes down. In their experiments, the researchers used a suspension that contained just 0.2 percent graphite flakes by volume. Such suspensions are remarkably stable: Particles remain suspended indefinitely in the liquid, as was shown by examining a container of the mixture three months after mixing. " Ref & story.

Carbon Nanotubes Twice as Strong as Once Thought
ScienceDaily (Sep. 16, 2010) — Carbon nanotubes -- those tiny particles poised to revolutionize electronics, medicine, and other areas -- are much bigger in the strength department than anyone ever thought, scientists are reporting. New studies on the strength of these submicroscopic cylinders of carbon indicate that on an ounce-for-ounce basis they are at least 117 times stronger than steel and 30 times stronger than Kevlar, the material used in bulletproof vests and other products.    ¶ The findings, which could expand commercial and industrial applications of nanotube materials, appear in the monthly journal ACS Nano.
