A 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 moreA catalyst's utility is influenced by its surface charge and how that charge is transferred. Until recently, studying charge transfer has relied on complex imaging techniques that are both expensive and time-consuming. Scientists now report an approach for studying charge transfer that does not rely on complicated equipment — simplifying the real-time observation of catalysis.

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 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 moreThe entry probe of the Galileo mission to Jupiter entered the planet's atmosphere in 1995 in fiery fashion, generating enough heat to cause plasma reactions on its surface. The data relayed about the burning of its heat shield differed from the effects predicted in fluid dynamics models, and new work examines what might have caused such a discrepancy. Researchers now report their findings from new fluid radiative dynamics models.
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.
