    Simple processes can make wood tough, impact-resistant—or even transparent Some varieties of wood, such as oak and maple, are renowned for their strength. But scientists say a simple and inexpensive new process can transform any type of wood into a material stronger than steel, and even some high-tech titanium alloys. Besides taking a star turn in buildings and vehicles, the substance could even be used to make bullet-resistant armor plates. Wood is abundant and relatively low-cost—it literally grows on trees. And although it has been used for millennia to build everything from furniture to homes and larger structures, untreated wood...

    Remote-controlled robots will journey to the bottom of the ocean in search of copper, nickel, cobalt, gold, and platinum as global demand for minerals surges. The world's first deep-sea mining operation will kick off in early 2019 when a Canadian firm, Nautilus Minerals Inc., lowers a trio of massive remote-controlled mining robots to the floor of the Bismarck Sea off the coast of Papua New Guinea in pursuit of rich copper and gold reserves. The machines, each the size of a small house, are equipped with rock-crushing teeth resembling the large incisors of a dinosaur. The robots will lumber across...

    Justice Department officials delivered materials to the House and Senate Intelligence Committees on Friday in connection to President Trump's claim that the Obama administration had his campaign headquarters wiretapped. "The Department of Justice has complied with the request from leaders of the House and Senate Intelligence Committees and Judiciary Committees seeking information related to surveillance during the 2016 election," Justice Department spokeswoman Sarah Isgur Flores told CNN.

    A young Emirati and a UAE based American nuclear chemist have developed what they claim is 'the next big thing in technology.' Mohammed Al Fahim, 29, and Dr. Lary A Burchfield, 65 - both working for the Nawah Energy Corporation - claimed their new theory of combining graphite with diamond has led to the discovery of a new molecule that acts like a semi-conductor. "Building a computer out of this will make the machine a millions times more powerful. Hence the discovery has the potential to change human lives," said Dr. Burchfield, Head of Environmental Radiochemistry Lab, at Nawah. He...

    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...

    Once again, graphene has proven itself to be a rather special material: an international research team led by Professor Fritz Aumayr from the Institute of Applied Physics at TU Wien was able to demonstrate that the electrons in graphene are extremely mobile and react very quickly. Impacting xenon ions with a particularly high electric charge on a graphene film causes a large number of electrons to be torn away from the graphene in a very precise spot. However, the material was able to replace the electrons within some femtoseconds. This resulted in extremely high currents, which would not be maintained...

    Through studying the geometry of strong structures, MIT researchers are now one step closer to 3D printing graphene. By comparison, 2D graphene is better at conducting electricity than copper wires, ten times stronger than steel, and lighter and certainly more transparent than both of them. The problem is that these properties as are all theoretical and scaling the nanomaterial has proved challenging. Furthermore, in order to compete with copper and steel, graphene has to be 3D. 3D graphene – here’s the deal The challenges of making a 3D structure out of a 2D material is that the material’s atomic structure,...

    He has said that the wall would be built from precast concrete and steel and that it could be 50 feet tall, if not higher. After calling for it to extend across the entire 2,000-mile southern border, he more recently said half that length could be sufficient because of natural barriers. He has pegged the cost at $4 billion to $12 billion, most recently settling on around $10b. Some see that as low. “There’s a lot of logistics involved in this, and I don’t know how thoroughly they’ve thought it out,” said Todd Sternfeld, chief executive of Superior Concrete, a...

    Jeffrey Grossman thinks we've been looking at coal all wrong. Instead of just setting it afire, thus ignoring the molecular complexity of this highly varied material, he says, we should be harnessing the real value of that diversity and complex chemistry. Coal could become the basis for solar panels, batteries, or electronic devices, he and his research team say. Read more at:

    Researchers were able to build the printer with off-the-shelf commodity parts for $7K.MIT researchers, using off-the-shelf components, have built a 3D printer capable of building with 10 photopolymer materials at once. And the school's Computer Science and Artificial Intelligence Laboratory (CSAIL) said the researchers were able to build the printer for less than $7,000. That compares to systems that print with just three materials at one time and can cost $250,000. The MultiFab 3D printer works by mixing together microscopic droplets of photopolymers that are then extruded through inkjet printheads similar to those in office printers. The printing process is...

    And it could be the key to understanding one of the biggest mysteries in physics today - high-temperature superconductors.An international team of scientists has announced the discovery of a new state of matter in a material that appears to be an insulator, superconductor, metal and magnet all rolled into one, saying that it could lead to the development of more effective high-temperature superconductors. Why is this so exciting? Well, if these properties are confirmed, this new state of matter will allow scientists to better understand why some materials have the potential to achieve superconductivity at a relativity high critical temperature...

    Graphene, a material formed of a mesh of hexagonal carbon atoms, has, according to ExtremeTech author Ryan Whitwam, “many fantastic properties that could change the course of human civilization. It’s chemically stable, highly conductive, and incredibly strong.” In a recent New Yorker article, John Colapinto stated graphene “may be the most remarkable substance ever discovered.” One thing graphene is not, however, is magnetic. Researchers at the University of California, Riverside have developed a way to induce magnetism in graphene while preserving its electronic properties. The research team did this by bringing a single sheet of graphene into close proximity to...

    ORANGE COUNTY, Fla. — Orange County school board members voted Tuesday evening to ban all religious materials from being distributed at public schools. In 2014, a group put Bibles in Orange County schools for one day, and another group was able to provide atheist materials. But it was when the satanic temple tried to put its own book in schools that the district's policy became an issue. The policy previously permitted the groups to leave religious materials on tables at schools at the beginning of the year on a nationally recognized freedom day. At Tuesday's meeting, board members voted 7-1...

The flagship project concept was initiated by the government to accelerate private businesses that have large growth potential. The first flagship project, which dealt with carbon fiber and energy storage systems, was initiated in May 2014. According to plans for the second flagship project, the government will support the development of a new cinema system that shows movies...

  • New Way to Make Lighter, Stronger Steel -- In a Flash

    A Detroit entrepreneur surprised university engineers here recently, when he invented a heat-treatment that makes steel 7 percent stronger than any steel on record in less than 10 seconds. In fact, the steel, now trademarked as Flash Bainite, has tested stronger and more shock-absorbing than the most common titanium alloys used by industry. Now the entrepreneur is working with researchers at Ohio State University to better understand the science behind the new treatment, called flash processing. What they've discovered may hold the key to making cars and military vehicles lighter, stronger, and more fuel-efficient. In the current issue of the...
