Researching the safety of nanoparticles is all the rage. Thousands of scientists worldwide are conducting research on the topic, examining the question of whether titanium dioxide nanoparticles or carbon nanotubes can get into the body’s lungs or blood. However, the amount of new knowledge has only increased marginally. How do nanoparticles get into the body? Researchers in Switzerland are attempting to establish standards.
Univ. of Texas at Arlington engineering professors have received an Air Force grant to examine the material surface at the micro- and nano-scale level that will provide clues for predicting fatigue in aircraft parts. The new approach will rely on a scanning whitelight interferometric surface profiler integrated with a compact mechanical tester and an electron backscatter diffraction module to deliver in-situ 3-D surface profiling.
Officials at a Chicago-based startup, Sagamore-Adams Laboratories LLC, say innovations discovered in Purdue University's School of Nuclear Engineering are being commercialized to address challenges in improving radiation detection and making sealants and adhesives safer. They have developed technology that could lead to radiation sensors that cost less and provide better information than traditional sensors.
Individuals in industrial associations, educational institutions and government organizations who are interested in composites, or materials made from constituent materials with different physical or chemical properties, now have free, 24/7 access to simulation tools through an online community with offices in the Purdue Research Park.
Smithers Rapra, a leading tester of rubber, plastics and composites, has launched the Testing Cost Comparison Calculator, a digital tool designed to compare the cost of testing internally to the cost of contracting testing to an independent, third party laboratory. The tool helps determine the need for the services of external testing labs, which can solve internal testing bottlenecks and facilitate product launches.
German drug company Merck says it has agreed to buy St. Louis-based chemical firm Sigma-Aldrich Corp. for $17 billion in a deal Merck says will strengthen its business in chemicals and laboratory equipment. Sigma-Aldrich has over 9,000 employees in 40 countries and supplies chemicals and laboratory equipment to government and commercial facilities. Its board of directors has unanimously approved the deal.
Glenn Johnson, CEO of BlueVine Graphene Industries Inc., said many of the methodologies being utilized to produce graphene today are not easily scalable and require numerous post-processing steps to use it in functional applications. He said his company has developed a way to scale graphene production using a roll-to-roll chemical vapor deposition process.
During the six-day IMTS manufacturing technology show in Chicago this week, the “Strati” will be the first vehicle printed in one piece using direct digital manufacturing. The process will take more than 44 hours of print time. A team including Local Motors, Cincinnati Inc. and Oak Ridge National Laboratory will then rapidly assemble it for a historic first set for Saturday.
When it comes to diesel engine catalysts, which are responsible for cleansing exhaust fumes, platinum has unfortunately proved to be the only viable option. This has resulted in material costs alone accounting for half of the price of a diesel catalyst. Researchers in Denmark say they have developed a new way to manufacture catalysts that may result in a 25% reduction in the use of platinum.
As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors. A team has figured out how to make electrodes from certain hemp fibers, and the breakthrough came from figuring out how to process them.
When concrete shells are constructed, they usually have to be supported by elaborate timber structures. This is one reason why such structures are now rarely built. In Austria, engineers have developed a new construction method that does not require any solid supporting structure at all. Instead, an air cushion is inflated below a concrete slab, bending the concrete and quickly forming a self-supporting shell.
In recent research in Germany, the desorption of oxygen molecules from a silver surface was successfully visualized for the first time using low-energy electron microscopy. The effects account for the shortcomings of conventional models of desorption, which often deliver rates that do not agree with experimentally determined values.
Although lubricants for machinery are widely used, almost no fundamental innovations for this type of product has been made in the last 20 years, according researchers in Germany who have been working on a new class of lubricating substance. Their new liquid crystalline lubricant enable nearly frictionless sliding because although it is a liquid, the molecules display directional properties like crystals do.
Are you an adhesives or coatings manufacturer? Do you need to adhesively join parts? Or, do you need durable non-stick coatings? Then, make plans to attend this meeting! Learn about new advanced materials and processing methods to either enhance adhesion or to create non-stick surfaces.
Researchers in Australia have created a micrometer thin film with record-breaking optical nonlinearity suitable for high-performance integrated photonic devices. To create the thin film the researchers spin coated graphene oxide solution to a glass surface. Using a laser as a pen they created microstructures on the graphene oxide film to tune the nonlinearity of the material.
Scientists at Battelle have developed a tiny bead that not only detects corrosion but delivers a payload to help heal the microscopic cracks that rust creates. Called the Battelle Smart Corrosion Detector, the beads look like a fine, whitish powder that can be mixed with coatings used to protect pipelines and other critical infrastructure subject to corrosion. Self-activating, they release a proprietary chemical that fills cracks.
Of all the electricity generated in the U.S., more than quarter is consumed by lighting. In 2010, North Carolina’s RTI International launched a new product, NLite, intended to help alleviate this burden by improving the reflectance performance of power-intensive lighting devices such as luminaires and liquid crystal displays. The technology, based on nanofiber reflectance polymers, won a 2011 R&D 100 Award.
Washing a car can be a costly and time-consuming chore. The European model of Nissan’s Note will be the first car to wear a new type of paint which could make car washes obsolete. The paint has been engineered to be super-hydrophobic and oleophobic, meaning it repels both water and oils. The tests may result in an aftermarket application.
Winners of R&D 100 Awards must often wait months or even years before the market decides their innovation can become a truly successful product. The editors at R&D follow the fortunes of many these winners, and we are often surprised at the way they can quickly transform entire industries. Recent announcements from R&D 100-winning companies like Newlight, Dow Chemical and Leica Microsystems reflect this level of success.
