Scientists 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.
