A multinational team of scientists has developed a process for creating glass-based, inorganic light-emitting diodes (LEDs) that produce light in the ultraviolet range. If successfully integrated into biomedical devices, these would be the first robust, cheap to produce, and chemically stable LEDs to operate in the medically-useful UV spectrum.
Fifteen years ago, an environmentally-friendly solder developed by Ames Laboratory became the first viable, cost-effective alternative to tin-lead solder. The successful tin-silver-copper alloy has now replaced an advanced mass spectrometer as the top royalty generator for both Ames and Iowa State University.
General Motors and Teijin Limited, a manufacturer of carbon fiber and composites, have announced they will co-develop advanced carbon fiber composite technologies for potential high-volume use globally in GM cars, trucks, and crossovers.
The Haber-Bosch process has long been used to convert atmospheric nitrogen into ammonia—essential in the manufacture of fertilizer—but scientists have had little understanding of how it actually works. A team of chemists at the University of Rochester have produced new insights into how ammonia is formed.
Oak Ridge National Laboratory has awarded a $13.2 million task order to AREVA Federal Services for fabrication of five drain tanks for the ITER tokamak cooling water system. ITER is an international project to demonstrate the feasibility of commercial fusion energy.
Based on more than nine years of research, a new pressure-volume-temperature (pvT) and thermal conductivity developed by engineers in the UK is intended to improve the design and processing of plastics, including the injection molding process used to make specialized polymers.
Diamonds can be produced artificially only under difficult conditions, and past predictions of the phase transitions involved have been theoretical because of simulation complexity. Advances in computing have allowed researchers in Switzerland to now show exactly how graphite is converted into diamond.
Using a structural laboratory, researchers at Purdue University have designed an experimental method of studying the behavior of buildings on fire. Thermal panels and hydraulic force generators are used to simulate the extreme heat of a structural blaze, and has delivered insights on the fire’s effects.
Because they subsist on the tough, woody bamboo plant, it makes sense that panda waste, according to scientists, contains bacteria with potent effects in breaking down plant material in the way needed to tap biomass.
With the introduction of a new chlorine manufacturing process achieved by combining oxygen depolarized cathode technology and new electrolysis technology, Bayer MaterialScience is poised to save enough electricity to power a small city.
Working together with a European automobile manufacturer, mPhase has produced a refined product with increased functionality over prior examples and a 20% reduction in size, using MEMS processing and microfluidics technologies.
When finished, the 4.2-meter mirror being crafted by the Univ. of Arizona’s College of Optical Sciences for the Advanced Technology Solar Telescope in Hawaii will be the largest telescope mirror ever pointed at the sun. Complicating the task of polishing this mirror is the shape: the telescope’s design calls for a complex off-axis paraboloid surface.
Unlike crystals, glasses lack a strict organization of repeating patterns. But sometimes they demonstrate atomic-scale order. New research from Carnegie’s Geophysical Laboratory reveals the possibility of creating a metallic glass that is organized on a larger scale: the perfect glass.
Because of its outstanding performance characteristics, polycarbonate resin is widely used to manufacture parts used in a myriad of industries. Now Bayer MaterialScience offering 2-D and 3-D solutions that offer greater scratch resistance for polycarbonate parts.
Making its largest single investment yet in clean energy, Google has inked a deal with photovoltaic installer SolarCity in an effort to help private homeowners put solar panels on their rooftops. The agreement is just one of the many recent renewable energy investments Google has made.
A Detroit entrepreneur surprised engineers at Ohio State University recently when he invented a heat-treatment that makes steel 7% stronger than any steel on record. An even bigger surprise was that his method, flash processing, takes less than 10 seconds.
Through his study of chemical reactions within concrete at the nanoscale, Jon Belkowitz, a doctoral student at Stevens Institute of Technology, plans to put an end to the problem of alkali silica reactivity, a chemical reaction that causes fissures in concrete as it sets.
Aldrich Materials Science, a strategic technology initiative of Sigma-Aldrich Corp., today announced it has signed an agreement to collaborate on the scale-up and commercialization of next-generation boron hydride hydrogen-storage materials with Ilika, a UK-based advanced cleantech materials discovery company.
One of China’s biggest, state-owned rare earths miners and producers has been given a monopoly over rare earth mining, processing, and trading in the northern part of the country. The move is an effort by the country’s government to bring the rare earths industry, which provides 97% of global supply, under tighter control.
Last month, a New Jersey Institute of Technology professor gave historians, who tend to think concrete architecture originated in Europe, some food for thought. According to Matt Burgermaster, Thomas Edison invented the single-pour system for building from concrete in 1917. Evidence remains in numerous examples of buildings in New Jersey, near where Edison’s factory was located.
The Geo-Cosmos is to be unveiled June 11 at the National Museum of Emerging Science and Innovation in Tokyo, Japan. Built by Mitsubishi Electric using 10,362 organic light-emitting diode panels, the giant 6-m globe will project clouds and other meteorological information obtained from satellites.
The “scratch test,” which tests a material’s resistance to deformation, might be the oldest known way to assess a material’s hardness and strength. Engineers at MIT decided to determine what exactly the scratch does assess. Using butter as a benchmark material, they found that the test does not actually measure material strength. But it does measure something else that is important.
A team of researchers from the University of Arizona and Rensselaer Polytechnic Institute have increased the toughness of ceramic composites by more than 200% with the use of graphene reinforcements. The graphene additions arrest the formation of cracks in the ceramic, forcing them to change direction in three dimensions.
Proprietary zinc finger technologies from biotechnology giant Sigma-Aldrich have been licensed by Kraig Biocraft Laboratories, which plans to back further R&D efforts and potentially commercialize the silk polymers in textile and biomedical fields.
Keeping silver’s tarnish at bay is a never-ending job, and every polish removes some of the precious metal. In an attempt to solve this millenia-old problem, researchers at the University of Maryland are testing a protective coating so thin it can’t be seen. Using atomic layer deposition, they apply nanometer-thick layers of aluminum oxide.
