Livermore Lab shines new light on novel additive manufacturing approach

April 17, 2014 - 3:18am
For nearly a century, electrophoretic deposition (EPD) has been used as a method of coating material by depositing particles of various substances onto the surfaces of various manufactured items. One of the most common and oldest processes that utilize EPD is the application of a primer coat to new car bodies on a production assembly line. The body of the car is positively charged while the liquid primer in the dunk tank is negatively charged, forcing the attraction of the primer to the metal surface.

Cheap, Better-Performing Lithium-ion Batteries with Nanowires

April 3, 2014 - 10:22am
Researchers at the USC Viterbi School of Engineering have improved the performance and capacity of lithium batteries by developing better-performing, cheaper materials for use in anodes and cathodes (negative and positive electrodes, respectively). Lithium-ion batteries are a popular type of rechargeable battery commonly found in portable electronics and electric or hybrid cars. Traditionally, lithium-ion batteries contain a graphite anode, but silicon has recently emerged as a promising anode substitute because it is the second most abundant element on earth and has a theoretical capacity of 3600 milliamp hours per gram (mAh/g), almost 10 times the capacity of graphite. The capacity of a lithium-ion battery is determined by how many lithium ions can be stored in the cathode and anode. Using silicon in the anode increases the battery’s capacity dramatically because one silicon atom can bond up to 3.75 lithium ions, whereas with a graphite anode six carbon atoms are needed for every lithium atom. The USC Viterbi team developed a cost-effective (and therefore commercially viable) silicon anode with a stable capacity above 1100 mAh/g for extended 600 cycles, making their anode nearly three times more powerful and longer lasting than a typical commercial anode.

Solution Processing of ITO-Free Solar Cells

March 27, 2014 - 4:36am
Organic solar cells (OSCs) are of interest for next-generation photovoltaic applications due to their lower costs and milder fabrication requirements relative to c-Si and thin-film devices. The power conversion efficiency (PCE) of these devices has risen to 11-12% in recent years, which is promising in order to gain market share in this competitive field. Requiring only simple spin- or dip-coating techniques, organic or polymer solar cells are an attractive low-cost technology; in recent years, there has been a focus on solution and roll-to-roll high throughput processing of OSCs to lower the fabrication costs even further.

Stanford Engineers Make Flexible Carbon Nanotube Circuits More Reliable and Efficient

March 19, 2014 - 7:28am
Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach involves designing circuits based on electronic fibers, known as carbon nanotubes (CNTs), instead of rigid silicon chips. But reliability is essential. Most silicon chips are based on a type of circuit design that allows them to function flawlessly even when the device experiences power fluctuations. However, it is much more challenging to do so with CNT circuits.

Rapid and Low-Cost Graphene Film Deposition using Solution Processing

March 5, 2014 - 4:06am
In 2004, a single layer of graphite known as graphene was synthesized for the first time via mechanical exfoliation of graphite. This discovery, for which Novoselov and Geim were awarded the Nobel Prize in Physics in 2010, has ushered in a 'graphene frontier' with worldwide interest in exploiting their intriguing potential for technological applications in fields such as nanoelectronics and energy storage. The primary method that is used to fabricate large-scale transparent graphene films is chemical vapor deposition (CVD). However, this requires high-temperature processing and relatively long deposition times. Furthermore, this precludes the deposition of graphene onto temperature-sensitive substrates. Although the deposited films may be flaked off the metallic (usually Cu) substrate for transfer to another surface, this will lead to the incorporation of impurities and structural defects.

Manufacturing Innovation Institutes Expand with Recent Announcement

February 28, 2014 - 5:04am
The administration has recently announced the latest awards for Manufacturing Innovation Institutes (http://manufacturing.gov/nnmi.html) (MIIs), a public-private partnership intended to boost advanced manufacturing while strengthening U.S. capabilities in defense, and creating sustainable economic impact and jobs through enhanced global competitiveness, and higher paying domestic jobs. Two new MIIs led by the Department of Defense supported by a $140 million Federal commitment combined with even larger non-federal resources are the Detroit-area headquartered consortium of businesses and universities with a focus on lightweight and modern metals manufacturing, and a Chicago headquartered consortium of businesses and universities that will concentrate on digital manufacturing and design innovation technologies. In concert with the announcement, the administration additionally delivered on it’s promise to continue the establishment of a network of MIIs throughout the U.S. by launching a competition for a new MII to build U.S. strength in manufacturing advanced composites as the first of four new competitions to be launched this year.  This announcement builds off the success of a pilot Additive Manufacturing Institute (https://americamakes.us/) (AMI) headquartered in Youngstown, Ohio awarded in 2012, along with the new Department of Energy-led Next Generation Power Electronics Manufacturing Innovation Institute (http://www.ncsu.edu/power/) in Raleigh, N.C., which was announced last month. The promise of 4 new MIIs pushes the U.S. over the top in achieving a critical goal of the administration, with broader impact to U.S. manufacturing, jobs, and sustainable economic impact. The new competition for an Advanced Composites Manufacturing Innovation Institute (http://www1.eere.energy.gov/manufacturing/newsandevents/news_detail.html?news_id=21300), led by the Department of Energy, will award $70 million over five years to improve U.S. capability to manufacture advanced fiber-reinforced polymer composites at the production speed, cost and performance needed for widespread use in clean energy products including fuel-efficient and electric vehicles, wind turbines and hydrogen and natural gas storage tanks.

SRC and MIT Extend High Resolution Lithography Capabilities

February 27, 2014 - 9:49am
MIT researchers sponsored by Semiconductor Research Corporation (SRC), the world’s leading university-research consortium for semiconductors and related technologies, have introduced new directed self-assembly (DSA) techniques that promise to help semiconductor manufacturers develop more advanced and less expensive components. The MIT research focuses on the issue of next-generation lithography in the semiconductor manufacturing process. Photolithography at a 193 nanometer (nm) wavelength is currently used for semiconductor device manufacturing, but that is reaching its limit with feature sizes around 25 nm. Electron-beam lithography can produce smaller features and is used for mask making, one of the critical steps in semiconductor manufacturing. However, the throughput of electron-beam lithography is currently insufficient for sub-20 nm resolution patterning over large areas.

Progress and Public Trust in Nanotechnology Require Better Material Characterization

February 27, 2014 - 7:32am
A prevalent challenge for progress in nanotechnology is characterization (http://www.internano.org/content/view/114/253/) [1 (#ref1), 2 (#ref2)]. Characterization, the measurement of various physicochemical properties of materials, is crucial for the evolution of nanotechnology from rudimentary nanomaterials and devices to those that are precision-engineered, mass producible, and safe. Each of the main sectors of nanotechnology – research, manufacturing, and regulation – needs systematic characterization in order to maximize knowledge and control of nanomaterials. Due to a number of factors, many of the nanomaterials that have been synthesized thus far are poorly defined, which can lead to false generalizations about performance and toxicity. The advancement of nanotechnology depends upon a coordinated effort made by researchers, manufacturers, regulators, and funding agencies to improve characterization techniques and practices so that well-defined and reproducible nanomaterials are studied and manufactured. An important consequence of thoroughly characterized materials will be increased public awareness, acceptance and use of nanotechnology.

Nano Counterfeit Protection for Space, Aviation and Defense Electronics

February 26, 2014 - 8:41am
Space and defense electronics are two of the most conservative markets in terms of new materials qualification – unless there is a pressing technical issue. Counterfeiting is a huge issue for space, where recall and repair are excruciatingly expensive, or impractical [1 (#ref1)][2 (#ref2)]. One of the root causes for a recent failure was alleged to be counterfeit SRAM memory chips. In aviation and defense, the problems may be due to the age of the systems and the reliance and rapid obsolescence of COTS (“commercial-off-the shelf”) electronics with a lifetime of a few years whereas weapons systems have lifetimes of decades. An extreme example is the B-52, first flown in 1952 with a projected retirement date of 2040! Couple this with data quoted by King that 57% of counterfeit-part reports from 2001 through 2012 involved obsolete components and we have a real problem.

Nanomanufacturing: Emergence and Implications for U.S. ...

February 12, 2014 - 10:07am
The forum's participants described nanomanufacturing as a future megatrend that will potentially match or surpass the digital revolution's effect on society and the economy. They anticipated further scientific breakthroughs that will fuel new engineering developments; continued movement into the manufacturing sector; and more intense international competition. Although limited data on international investments made comparisons difficult, participants viewed the U.S. as likely leading in nanotechnology research and development (R&D) today. At the same time, they identified several challenges to U.S. competitiveness in nanomanufacturing, such as inadequate U.S. participation and leadership in international standard setting; the lack of a national vision for a U.S. nanomanufacturing capability; some competitor nations' aggressive actions and potential investments; and funding or investment gaps in the United States (illustrated in the figure, below), which may hamper U.S. innovators' attempts to transition nanotechnology from R&D to full-scale manufacturing.
