Next Round of Manufacturing Innovation Institutes Include Nanomanufacturing Opportunities

National Nanomanufacturing Network - February 27, 2015 - 2:48am
Recent announcements by the federal government identifying the next rounds of Manufacturing Innovation Institutes (MIIs) have selected topics for public-private funding opportunities that potentially provide opportunity for nanomaterials and nanomanufacturing technologies. The selected topics, which include $200M in public-private funding for an Integrated Photonics Institute (IP) (http://manufacturing.gov/ip-imi.html), and $150M a Flexible Hybrid Electronics (FHE) Institute (http://www.manufacturing.gov/fhe-mii.html), each have critical aspects enabled through nanotechnology. Flexible hybrid electronics inherently incorporate printed electronics that involve the processing of various inks containing nanomaterials, such as carbon nanotubes, graphene, or metallic and metal oxide nanoparticles. Similarly integrated photonics exploit innovative materials and processes in order to create integrated optical or photonic devices and systems utilizing nanostructures and nanoscale patterning techniques. Flexible Hybrid Electronics are enabled through innovative manufacturing processes adapted from traditional industry approaches that preserve the full operation of traditional electronic circuits in flexible architectures. The technology demonstrators for manufacturability are intended to exhibit novel flexible form factors that are conformal, bending, stretching, or folding, and address a range of emerging applications in human activity and health monitoring, ubiquitous sensors (i.e.; the Internet of Things), or wearable electronics. The manufacturing institute will address issues including standards, materials, process scale-up, design tools, and advanced manufacturing. The Integrated Photonics Manufacturing Institute will focus on developing an end-to-end photonics ecosystem in the U.S., including domestic foundry access, integrated design tools, automated packaging, assembly and test, and workforce development. The manufacturing innovation institute will serve as a regional hub, bridging the gap between applied research and product development by bringing together companies, universities, and other academic and training institutions and Federal agencies to co-invest in key technology areas that encourage investment and production in the U.S.

New Paper-like Material Could Boost Electric Vehicle Batteries

National Nanomanufacturing Network - February 26, 2015 - 7:55am
Researchers create silicon nanofibers 100 times thinner than human hair for potential applications in batteries for electric cars and personal electronicsResearchers at the University of California, Riverside’s Bourns College of Engineering (http://www.engr.ucr.edu/) have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery. This paper-like material is composed of sponge-like silicon nanofibers more than 100 times thinner than human hair. It could be used in batteries for electric vehicles and personal electronics. The findings were just published in a paper, “Mihri Ozkan (http://www.ee.ucr.edu/%7Emihrilab/), a professor of electrical and computer engineering, Cengiz S. Ozkan (http://www.engr.ucr.edu/%7Ecengizlab/), a professor of mechanical engineering, and six of their graduate students: Zach Favors, Hamed Hosseini Bay, Zafer Mutlu, Kazi Ahmed, Robert Ionescu and Rachel Ye. The nanofibers were produced using a technique known as electrospinning, whereby 20,000 to 40,000 volts are applied between a rotating drum and a nozzle, which emits a solution composed mainly of tetraethyl orthosilicate (TEOS), a chemical compound frequently used in the semiconductor industry. The nanofibers are then exposed to magnesium vapor to produce the sponge-like silicon fiber structure. Conventionally produced lithium-ion battery anodes are made using copper foil coated with a mixture of graphite, a conductive additive, and a polymer binder. But, because the performance of graphite has been nearly tapped out, researchers are experimenting with other materials, such as silicon, which has a specific capacity, or electrical charge per unit weight of the battery, nearly 10 times higher than graphite. The problem with silicon is that is suffers from significant volume expansion, which can quickly degrade the battery. The silicon nanofiber structure created in the Ozkan’s labs circumvents this issue and allows the battery to be cycled hundreds of times without significant degradation. “Eliminating the need for metal current collectors and inactive polymer binders while switching to an energy dense material such as silicon will significantly boost the range capabilities of electric vehicles,” Favors said. This technology also solves a problem that has plagued free-standing, or binderless, electrodes for years: scalability. Free-standing materials grown using chemical vapor deposition, such as carbon nanotubes or silicon nanowires, can only be produced in very small quantities (micrograms). However, Favors was able to produce several grams of silicon nanofibers at a time even at the lab scale. The researchers’ future work involves implementing the silicon nanofibers into a pouch cell format lithium-ion battery, which is a larger scale battery format that can be used in EVs and portable electronics.Source: UCR Today (http://ucrtoday.ucr.edu/27263)

Flexible Nanosensors for Wearable Devices

National Nanomanufacturing Network - February 26, 2015 - 7:44am
Researchers from UPM have developed a manufacturing method of aluminum optical nanosensors on versatile substrates that can be used for wearable devices and smart labels. A new method developed at the Institute of Optoelectronics Systems and Microtechnology (http://www.isom.upm.es/eng/index.php) (ISOM) from the Universidad Politécnica de Madrid (http://www.upm.es/internacional) (UPM) will enable the fabrication of optical nanosensors capable of sticking on uneven surfaces and biological surfaces like human skin. This result can boost the use of wearable devices to monitor parameters such as temperature, breath and heart pressure. Besides, it is a low cost technology since they use materials like standard polycarbonate compact disks, aluminum films and adhesive tapes that would facilitate its implementation on the market.Researchers from Semiconductor Devices Group (http://www.upm.es/observatorio/vi/index.jsp?pageac=grupo.jsp idGrupo=260) of ISOM from UPM have not only designed a manufacturing method of optical nanosensors over a regular adhesive tape but also have shown their potential applications. These flexible nanosensors enable us to measure refractive index variations of the surrounding medium and this can be used to detect chemical substances. Besides, they display iridescent colors that can vary according to the viewing and illumination angle, this property facilitates the detection of position variations and surface topography to where they are stuck at a glance. Nanosensors consist of dimensional nanohole arrays (250 nm) which are drilled into an aluminum layer (100 nm thick). In order to cause sensitivity to the surrounding mediums and iridescence effects, these nanostructures confine and disperse light according to the will of the engineer who designs them. The creation method for flexible nanosensors consists, firstly, on manufacturing sensors over a compact disc (CDs) of traditional polycarbonate, and secondly, transferring these sensors to adhesive Scotch tapes by a simple stick-and-peel procedure. This way, the nanosensors go from the CD surface to the adhesive tape (flexible substrate). The stick-and-peel process can be watched at: http://1drv.ms/1Jgf6Hd (http://1drv.ms/1Jgf6Hd) This new technology uses low cost materials such as polycarbonate CDs, aluminum, and regular adhesive tapes. The usage of noble metals to develop these types of sensors is common, but it is difficult mass production due to the high cost. Aluminum is 25,000 times cheaper than gold and has excellent electrical and optical properties. Besides, CD surfaces provide adherence to aluminum that is strong enough to manufacture the sensors over the CDs and weak enough to be transferred to the adhesive tape. This research is led by Dr. Carlos Angulos Barrios, a researcher from ISOM and Professor at the Department of Photonics Technology and Bioengineering (http://www.tfo.upm.es/) (TFB) of the School of Telecommunications Engineering (http://www.etsit.upm.es/index.php/en/), and also led by Víctor Canalejas Tejero, a PhD student of ISOM. The results were published in the Nanoscale journal ("Compact discs as versatile cost-effective substratesfor releasable nanopatterned aluminium films" (http://pubs.rsc.org/en/Content/ArticleLanding/2015/NR/C4NR06271J#!divAbstract) ).Source: Universidad Politécnica de Madrid (http://www.upm.es/internacional/UPM/UPM_Channel/News/03db4bb9a70cb410VgnVCM10000009c7648aRCRD)
