December 10th, 2019 - A newly discovered Superconductor Material May Be the ‘Silicon of Quantum Computers’-A possible useful material to be used for building quantum computers has been discovered at the National Institute of Standards and Technology (NIST). The scientists at NIST have found a superconductor that could go around the primary obstacles standing in the way of effective quantum logic circuits.
The discovered new properties of the compound uranium ditelluride (UTe2), show that it may be highly resistant to one of the obstacles in quantum computer development — the difficulty with making such a computer’s memory storage switches, called qubits, work long enough to finish a computation before losing the delicate physical relationship that allows them to operate as a group. This relationship, called "quantum coherence", is hard to maintain because of interference from the real world.
The compound’s strong resistance to magnetic fields makes it a unusual among superconducting (SC) materials, these materials offer many advantages for qubit design, especially their resistance to the errors that can easily derial quantum computating. UTe2’s properties may make it attractive to the infant quantum computer industry.
Sept. 1st, 2019 - A recent study examined the Biological Risk Potential of Carbon Nanoparticles. A collaborative research team from the Heinrich Heine University Düsseldorf (HHU) studied the nature of carbon nanoparticles to determine whether they are harmful to organisms and how cells deal with them after they have been integrated into the cell. Results of the study were recently published in the Scientific Reports journal. The scientists used nanoparticles fabricated from graphene and the study indicated that the cells absorbed the nanoparticles and did not show significant changes when they were treated with nanoparticles.
July 1st, 2019 - Scientists NIST (National Institute of Standards and Technology) have demonstrated “quantum squeezing” to amplify and measure trillionths-of-a-meter motions of a single trapped magnesium ion (electrically charged atom).
March 30th, 2019 - Theoretical physicist Philip Russell Wallace predicted graphene’s existence in 1947, but it was’t until the 1960s that scientists began looking for it in earnest. Forty years later, researchers Geim and Novoselov figured out how to isolate graphene with transparent tape and graphite (pencil lead). This gallery shows some beautiful Electron Micr scope images of graphene.
March 29th, 2019 - Electrospinning uses electric fields to control microscale and nanoscale fibers. This method is sound but tedious, expensive and time-consuming. Researchers from Michigan Technological University have devised a new way to grow nanofibers which involves growing cell cultures which reduces the time required for removing toxic chemicals and solvents.

June 5th, 2018 - Water Insulators. In a research collaboration, North Carolina State University, Oak Ridge National Laboratory (ORNL) and Texas A&M University have developed what some consider to be water insulators used for energy storage applications. In the project, researchers sandwiched water molecules between two materials, which enables higher power storage devices with higher efficiency. In essence, researchers developed a compound called crystalline tungsten oxide dehydrate. The compound consists of crystalline tungsten oxide layers, which are separated by thin layers of water.
