  • Graphene-fed Spiders and Our Web of Resource Dependencies 

    A material long hailed as being on the cutting edge of materials science, Graphene is making headlines again. And, fitting for fall and people gearing up for Halloween, it involves everyone’s favorite creepy crawlies – arachnids. 
    Researchers at the University of Trento in Italy have found that spiders fed with graphene and carbon nanotubes, which had been added to their drinking water, produced silk that was five times stronger, making the webs they built as strong as carbon fibers and Kevlar, which are considered the strongest materials on Earth, according to a recent article in Futurism.   

    The unique properties and versatility of Graphene, a single layer of carbon atoms, prompted the European Commission to designate the material an FET – a “Future & Emerging Technologies” Flagship, dedicating a 10-year, 1 billion Euro research and innovation initiative to Graphene.  

    The Italian researchers’ discovery is another case in point of how Materials Science is finding new uses for materials, thus shifting the paradigms of resource supply and demand. 

    Graphite, from which Graphene is derived is also a key material we will need for next-gen energy storage systems. Meanwhile, the U.S. currently produces zero Graphite, with the last American Graphite mine having closed 25 years ago. Once again, the U.S. finds itself 100% import dependent, relying to a great extent on Chinese supplies of Graphite to meet domestic needs. 

    We may not be trapped in webs built by Graphene-doped spiders anytime soon, but the possibilities of harnessing the potential of this discovery seem endless. We are, however, already entangled in a web of foreign mineral resource dependencies, which represent a “clear and present danger” for the U.S., as ARPN’s Dan McGroarty recently outlined in his commentary for Investor’s Business Daily.  It’s time our policy makers took note. 

  • Boron: Of “Slime,” Materials Science and Trade Balances

    If you have preschoolers or grade schoolers at home on summer break, chances are you’ve already had to make “slime.”   Researching the various recipes to make the latest kids’ craze, you will likely also have come across one often-used ingredient: Borax.

    While Borax has long been a traditional staple in American laundry rooms, borates are increasingly becoming key components of cutting-edge gadgetry and technology.

    Most recently, scientists at UCLA have released their findings regarding a new technique using Silicon and Boron to break carbon-hydrogen bonds and make carbon-carbon bonds.  In doing so, they have overcome one of the big challenges of molecular science – the strong bond between carbon and hydrogen bonds – without using rare and expensive elements like Iridium.

    Of particular interest to the energy industry, which has been seeking ways to turn simple hydrocarbon molecules into new fuels, this new method “will enable scientists to incorporate methane into bigger molecules,” says UCLA assistant professor of chemistry and biochemistry Hosea Nelson.

    The UCLA research team touts other possible applications: 

    “Another potential application would be converting methane, one of the primary components of natural gas, into something that’s denser and easier to contain after it has been drilled from Earth. The current process is complicated because methane, a light gas, tends to escape into the atmosphere.

    Furthermore, because the technique used by the researchers can be performed at “temperatures and gas pressures that are easily attainable in a laboratory” and allows for the assembly of complex molecules in fewer reaction steps that previously possible, chemical and pharmaceutical manufacturers could save both time and money.  Ultimately, the molecules in existing pharmaceuticals might be altered to be made more effective, safer, or less addictive.

    This development will in all likelihood not impact the United States’ supply scenario for Borates – after all Borates are one of the few minerals of which we are a net exporter.   It does, however, once more underscore how materials science is a real game-changer in how we should look at mineral resources and underlying policies.

    In the case of Boron, the United States boasts a strong production base ensuring supply not only for our domestic needs but also for our trading partners’ needs. A single mine in California supplies roughly 30 percent of the world’s demand for refined Borates.

    As we previously pointed out:

    “With mining exports making considerable positive contributions to America’s trade balance, policy makers and other stakeholders should embrace policies that encourage the development of the mineral resources we are blessed to have beneath our own soil – not just for those where our demand exceeds supply, but for those like Boron, where U.S. production supplies the world.”

  • Advances in Materials Science Warrant Rethink in Resource Policy

    We appreciate them for their traditional applications, but metals like Copper and Tin are far more than your mainstay materials.  We discussed their Gateway Metal status here, but it’s not just the fact that their development yields access to some of the most sought-after tech metals that makes them so indispensible – it’s advances in materials [...]
  • Urban Mining – No Panacea but Important Piece of the Resource Strategy Puzzle

    Advances in materials science continue to transform the way we use metals and minerals, and in doing so, also change the supply and demand scenarios for many materials. As we recently pointed out on the ARPN blog, demand for Cobalt has been soaring thanks to its applications in battery technology and the growing popularity of electronic [...]
  • Through the Gateway: Scandium Embodies Materials Science Revolution

    As we near the conclusion of our journey “Through the Gateway,” we noticed that one metal has kept popping up in our coverage – Scandium. A co-product of Tin, we also discussed it in the context of the alloying properties of Gateway Metal Aluminum. It is also a co-product of Nickel. There is good reason it keeps popping up. For [...]
  • Through the Gateway: Rhodium – Not Just Another Platinum Group Metal

    A rare, silvery white, hard and corrosion-resistant metal, Rhodium is not only one of Palladium’s fellow members of the Platinum Group Metals (PGMs); it, too, happens to be a Nickel co-product.  And, as is the case with Palladium, one of Rhodium’s main uses is in catalytic converters to reduce automobile emissions, as well as in industrial catalysts. Alloyed with [...]
  • Through the Gateway: Aluminum Alloys – Versatility On Steroids

    Last year, researchers developed a material “that’s as strong and light as titanium, another expensive material, but at just a tenth of the cost.” They were able to achieve this feat by tweaking Aluminum’s alloying properties at the nano level. Aluminum’s properties as a stand-alone metal already make it one of the most versatile materials in engineering and [...]
