    Phys Org ^ | September 19, 2017
    Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene. They can be found in your computer, in your mobile phone, in almost all other electronic equipment and in many of the plastics around you. Society is highly dependent on scarce metals, and this...

    Shots fired. Well, things are certainly getting heated between competitors in the auto industry right now. A BMW executive recently described the Mercedes X-Class luxury pickup as “appalling,” despite admitting that the firm is considering entering the premium pickup segment. Then Lewis Hamilton taunted Ferrari claiming that AMG can build a better supercar. And now the boss of Hyundai and Genesis seemingly got out the wrong side of the bed one morning, accusing luxury automakers like BMW and Mercedes of putting too much focus on “stupid” tech. The head of Hyundai’s N and Genesis divisions Albert Biermann, who also used...

    The South China Morning Post ^ | August 6, 2017 | Celia Chen
    Foxconn Technology Group, the world’s largest contract manufacturer of consumer electronics, said it’s planning a multibillion dollar investment in the US state of Michigan, a week after announcing a US$10 billion plant in Wisconsin, giving a shot in the arm to Donald Trump’s election pledge to lure investments and create jobs for Americans. The new plant will be engaged in the research, development and production of components and vehicles that can drive autonomously, said Terry Gou, founder of the Taiwanese company, on Saturday in Shenzhen. “Automotive development in the US is still more advanced than China,” said Gou, declining to...

    The Bismark Tribune ^ | July 4, 2017 | Jessica Holdman
    North Dakota coal companies are hoping to have a hand in solving the nation’s supply problem of rare earth elements. Europium, dysprosium, erbium, terbium, neodymium, holmium, scandium, lutetium, and yttrium, are just a few of these valuable materials. “They’re used in pretty much all of our modern electronics,” said Steve Benson, associate vice president for research at the Energy and Environmental Research Center in Grand Forks. Magnets, hard drives, alloys, batteries, catalysts in cars, lasers, even coal’s cleaner energy cousins wind turbines and solar panels rely on rare earth elements - and could, in turn, rely on lignite coal. And...
  • Why the grim reaper of retail hasn't come to claim Best Buy

    Los Angeles Times ^ | 07/18/2017 | By James F. Peltz and Jack Flemming
    Five years ago Best Buy Co. looked like a retail dinosaur, another victim of e-commerce juggernaut Amazon.com and other online sellers. The big-box electronics chain was suffering dwindling sales and profits due in good part to “showrooming,” when shoppers would come in to a Best Buy store to check out televisions, computers and other items in person, and then buy them at cheaper prices at Amazon or elsewhere online. Best Buy also was struggling with executive turmoil and facing a buyout threat from a major stockholder. The chain in 2012 named a new chief executive, Hubert Joly, but the Frenchman...

  • Chemists create 3D printed graphene foam

    06/26/2017 1:38:56 AM PDT · by 2ndDivisionVet · 1 replies
    Nanotechnologists from Rice University and China's Tianjin University have used 3-D laser printing to fabricate centimeter-sized objects of atomically thin graphene. The research could yield industrially useful quantities of bulk graphene and is described online in a new study in the American Chemical Society journal ACS Nano. "This study is a first of its kind," said Rice chemist James Tour, co-corresponding author of the paper. "We have shown how to make 3-D graphene foams from nongraphene starting materials, and the method lends itself to being scaled to graphene foams for additive manufacturing applications with pore-size control." Graphene, one of the...

    In a move that will likely make the Trump administration really happy, a major manufacturer is shifting jobs from China to the U.S. Foxconn, the company known for making iPhones and other big-name gadgets, plans to invest $10 billion in a production plant in the U.S — specifically somewhere in Ohio, Pennsylvania, Michigan, Illinois, Wisconsin, Indiana or Texas. The plant could create up to 50,000 new jobs. President Trump hinted at this deal in June while visiting Wisconsin for his "workforce development" tour. "Just backstage, we were negotiating with a major, major, incredible manufacturer of phones and computers and televisions,"...

    As reported recently in the journal Nature Communications, a team of researchers from the University of Central Florida (UCF), CREOL and the University of Texas have developed a graphene-based transistor that could one day lead to super-fast and super energy-efficient computers. By super-fast we mean a thousand times faster and by super energy-efficient we mean it will only use a hundredth of the power. Right now, the world of electronics relies on silicon-based transistors to power its devices. And while their invention made it possible for devices to be reduced to smaller sizes as the transistors allowed the flow of...

    University of Illinois at Chicago scientists have discovered a new chemical method that enables graphene to be incorporated into a wide range of applications while maintaining its ultra-fast electronics. Graphene, a lightweight, thin, flexible material, can be used to enhance the strength and speed of computer display screens, electric/photonics circuits, solar cells and various medical, chemical and industrial processes, among other things. It is comprised of a single layer of carbon atoms bonded together in a repeating pattern of hexagons. Isolated for the first time 15 years ago by a physics professor at the University of Manchester in England, it...

    A team of researchers at the Israel Institute of Technology has developed a new capacitor with a metal-insulator-semiconductor (MIS) diode structure that is tunable by illumination. The capacitor, which features embedded metal nanoparticles, is similar to a metal-insulator-metal (MIM) diode, except that the capacitance of the new device depends on illumination and exhibits a strong frequency dispersion, allowing for a high degree of tunability. This new capacitor has the potential to enhance wireless capability for information processing, sensing and telecommunications. The researchers report their findings this week in the Journal of Applied Physics. "We have developed a capacitor with the...
  • Embarrassment of Riches: Reversing U.S. minerals import dependency

    R Street ^ | May 25, 2017 | Ned Mamula and Catrina Rorke
    As recently as 1990, the United States was the world’s largest producer of minerals—a collection of nonfuel resources that are the building blocks of today’s technologies. In the ensuing decades, quite a different trend has emerged. Of 88 mineral commodities tracked by the U.S. Geological Survey (USGS), the United States is more than 25 percent import-dependent for 62 of them. That trend is growing worse. In its annual Mineral Commodity Summary, USGS notes: Several U.S. metal mines and processing facilities were idled or closed permanently in 2016, including iron ore mines in Michigan and Minnesota; three primary aluminum smelters in...

    I attended the Consumer Electronics Show in Las Vegas in 2011. It's the world's largest trade show, with hundreds of new products introduced each year. What I saw were booths stuffed with future landfill: docks, dashboard mounts, adapters, robotic vacuum cleaners, 3D TVs. One afternoon, I attended a panel discussion about the rapidly approaching "connected home," referred to nowadays as the Internet of Things. The panelists promised that household devices of all kinds would soon be connected to one another and to the internet, thereby transforming the average American home into a futuristic fortress of hyperefficiency.

    INDIANAPOLIS — Consumer electronics chain hhgregg Inc. is going out of business and shutting down all its stores. Founded in 1955, the retailer had 220 stores in 19 states selling major appliances like washers and TVs, as well as computers and home theater systems. As of May last year, it had about 5,000 employees. Just days before announcing its bankruptcy protection filing last month, hhgregg said it planned to trim down by closing three distribution centers and 88 stores. But the move was not enough to salvage the chain.

    Anyone who has a portable device — including smartphones, tablets, laptops, smartwatches and fitness trackers — is obviously familiar with a lithium-ion (Li-ion) battery because most (if not all) of these devices are powered by this kind of battery. We’ve been okay with the rechargeable for a while, but as lithium-ion batteries are now close to reaching their maximum storage capacity (in other words, battery life can’t be extended any more), and with the horror stories about phone batteries that explode or burn, the search is on for an alternative battery that can meet our demands better and safer. So...

    It seems that on a monthly basis, there is a new development in the speed and quality of graphene production, be it with copper substrates, or using it to create the strongest material known to humankind. Yet despite these regular developments, little progress has been made in producing the so-called wonder material faster and cheaper to the point that it can be mass-produced. However, the latest development from Kansas State University (KSU) is certainly taking graphene to a new, explosive level of development. Unlike current production methods that rely on large industrial-scale equipment, the KSU team led by Prof Chris...

    Today, Arctic Star Exploration Corp. (ADD.V) reported to have started permitting for a drill program on its wholly owned CAP Property, located within the central parts of the Rocky Mountain Rare Metal Belt, 80 km northwest of Prince George in British Columbia, Canada. In 2010, Arctic Star acquired this property for its potential to host niobium-tantalum and/or rare earth elements ("REEs"). Since then, these commodities have undergone a dramatic shift in demand owing in part to their usage in the green energy sector, which includes modern wind turbines, rechargeable batteries, catalytic convertors etc. Past exploration identified a large anomaly to...
