Researchers have developed an affordable, reliable paper-based sensor that works with a cellphone app to detect levels of iron in fortified food products.
Read moreA team chemically engineered carbon nanotubes to synthesize and trap trions at room temperature. Trions are quasi particles that can potentially carry more information than electrons in applications from bioimaging to chemical sensing and quantum computing. The research makes it possible to manipulate trions and study their fundamental properties in ways that have never been possible before.
Read moreThe researchers used machine-vision automation and parallelization to simultaneously produce globally aligned, single-wall carbon nanotubes using pressure-driven filtration.
Read moreScientists are studying the fabrication of polymeric nanofibers and microfibers — very thin fibers made up of polymers. The fibers can be woven into textile-like structures but depending on the use, different fiber thicknesses may be necessary. To study the effects of various parameters on fiber fabrication, the researchers compared the characteristics of fibers created in different ways.
Read moreA phenomenon that has previously been seen when researchers simulate the properties of planet cores at extreme pressures has now also been observed in pure titanium at atmospheric pressure. Chains of atoms dash around at lightning speeds inside the solid material.
Read moreChemists have created a new material that self-assembles into 2D networks in a predictable and reproducible manner. They have successfully synthesized a complex material by design — paving the way for its suite of new properties to be applied in many fields.
Read moreScientists use the plasmonic properties of gold nanoparticles to amplify light from molecules triggered by electrochemiluminescence. The work could help researchers analyze the active surfaces of catalysts and other materials at the nanoscale.
Read moreScientists have created a nano-electronic circuit which vibrates without any external force. Just as a guitar string vibrates when plucked, the wire — 100,000 times thinner than a guitar string — vibrates when forced into motion by an oscillating voltage. The surprise came when they repeated the experiment without the forcing voltage. Under the right conditions, the wire oscillated of its own accord. The nano-guitar string was playing itself.
Read moreNew research shows that unique materials with distinct properties akin to those of gecko feet – the ability to stick to just about any surface — can be created by harnessing liquid-driven chaos to produce soft polymer microparticles with hierarchical branching on the micro- and nanoscale.
