Chemists 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 morePartial unfolding of proteins can be a major challenge in the industry, as it may affect the stability of products. So how does an empty space or cavity in its hydrophobic core destabilize a protein? And would such a cavity, in fact, be empty? These are some of the questions that researchers answer in a new study.
Read moreA team of acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can also 'swallow' low frequencies very well, as they report.
Read moreResearchers have fabricated a self-assembled, carbon-based nanofilm where the charge state (ie, electronically neutral or positive) can be controlled at the level of individual molecules. Molecular self-assembly on a metal results in a high-density, 2D, organic quantum-dot array with electric-field-controllable charge state, with the organic molecules used as 'nano-sized building blocks' in fabrication of functional nanomaterials. Achieved densities are an order of magnitude larger than conventional inorganic systems.
Read moreAn international team of scientists has developed a genetic engineering tool that makes producing and analyzing microbial secondary metabolites — the basis for many important agricultural, industrial, and medical products — easier than ever before, and could even lead to breakthroughs in biomanufacturing.
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 moreResearchers have shown for the first time that a cheap catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial electrolyzer — a step toward clean, large-scale hydrogen production for fuel, fertilizer and industry.
Read moreControlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society. With the boom of nanotechnology in recent years, the nanoscale manipulation of light has become both, a promising pathway to continue this advancement, as well as a unique challenge due to new behaviors that appear when the dimensions of structures become comparable to the wavelength of light.
