Physicists and educators have developed a curriculum for college-level students that shows promise in helping students in introductory physics classes further practice and develop their calculus skills.
Read moreA hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now researchers have determined just how unlikely it is.
Read moreFor the first time researchers successfully used laser pulses to excite an iron-based compound into a superconducting state. This means it conducted electricity without resistance. The iron compound is a known superconductor at ultralow temperatures, but this method enables superconduction at higher temperatures. It is hoped this kind of research could greatly improve power efficiency in electrical equipment and electronic devices.
Read moreResearchers have developed a rewriteable paper coating that can encrypt secret information with relatively low-tech invisible ink — water. A message printed out by a water-jet printer on a manganese-complex-coated paper is invisible to the naked eye, but the message reveals itself under 254 nm UV light. The paper can be ready for another round of printing after erasing the message by heating it with a blow dryer for 15-30 seconds. The method allows reversible secure printing for at least 30 cycles.

Read moreNew research has resulted in a reactive copper-nitrene catalyst that pries apart carbon-hydrogen (C-H) bonds and transforms them into carbon-nitrogen (C-N) bonds, which are a crucial building block for chemical synthesis, especially in pharmaceutical manufacturing.
Read moreHey, physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials — members of the platinum family — when they are ultra-thin. Iridium 'loses its identity' and its electrons act oddly in an ultra-thin film when interfaced with nickel-based layers, which have an unexpectedly strong impact on iridium ions.
Read moreNew technique enables implantation of individual ions into crystals with an accuracy of 35 nanometers.
Read moreA group of researchers found that when light was exposed to the surface of a tetracene alkanethiol-modified gold nanocluster, which they developed themselves, twice as many excitons could be converted compared to the number of photons absorbed by the tetracene molecules. These findings are expected to contribute to areas such as solar energy conversion, electronics, life sciences, and medical care in the future.
