These materials have mechanical and electrical properties that are useful in applications such as sonar and ultrasound. The more scientists understand about the nanoscale short-ranged “local structures” that exist inside relaxor ferroelectrics, the better materials we can develop for these and other applications.1
In a recent work, Masayo Suzuki et. al.1 have reported the development of a high-flux X-ray monitor based upon the scintillation of Ar gas as X-rays pass through it. Unlike ion chambers, where the temporal response is limited by the drift velocity of charged particles in gaseous media, it is possible for Ar-scintillation monitors to yield time resolution better than 50 ns.
At CHESS, we have created a device that uses the same principle as the one mentioned above with the added capability of measuring X-ray beam position, in addition to flux.
The international user base was represented by 174 attendants who congregated to discuss this year's theme, "Exploring the Art and Science of Synchrotron X-ray Research". The plenary session on June 10 included a morning facility update session with the CHESS and MacCHESS directors, where exciting upgrade plans were presented, along with a summary of updates to the beam time proposal system. The invited user science sessions featured a cross-section of cutting edge user research, spanning the range from virology to superconductivity to art conservation.
Over the past decade, such strange entities as magnetic monopoles, Majorana fermions, and even Higgs modes have been predicted and identified inside materials at low temperatures. The goal of learning to manipulate these new quanta for technological purposes is a grand challenge for science, predicted to spark a "second quantum revolution". Among the intriguing zoo of new particles which exploit the topological properties of electronic wavefunctions, the Weyl fermions (which are charged, massless, and chiral) were originally postulated in the 1920s but have never bee
Most commercial rechargeable batteries are based on lithium ion intercalation into layered metal oxides, the mechanism of which is fairly well understood. To move forward in the development of better electrode materials, deeper insights into heretofore unexplored methods of charge storage must be gained.
Their potential application is, however, currently limited as HOIPs shows structural instability under high temperature, humidity, or even extended light exposure. Understanding of the perovskite structural stability and phase transitions is deemed both timely and essential.
