Lanthanide-doped upconversion nanoparticles emerged recently as an attractive material platform for light emission. It underpins various innovative applications such as optical cryptography, luminescent probes, and lasing. An effective strategy for achieving ultrabright and dual-band polarized upconversion photoluminescence is presented.
From atomic nuclei to astrophysics, collaborative program builds basis for scientific discoveries
Oak Ridge National Laboratory is leading two nuclear physics research projects within the Scientific Discovery through Advanced Computing, or SciDAC, program from the Department of Energy Office of Science. One of the projects is called Nuclear Computational Low-Energy Initiative, or NUCLEI. The other is Exascale Nuclear Astrophysics for FRIB, or ENAF.
Observing the Coherent Motion of Electrons with an Attosecond Stopwatch
Electrons can display interference effects like waves in the ocean, but this happens on extremely fast time scales. In this study, scientists observed the quantum mechanical motion of electrons in an excited molecule using an "attoclock," which measures electron motion with a precision of hundreds of attoseconds. The experiment advances the study of electron dynamics and will improve understanding of molecular physics and quantum chemistry.

Grasping entropy: Teachers and students investigate thermodynamics through a hands-on model
Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. In The Physics Teacher, co-published by AIP Publishing and the American Association of Physics Teachers, T. Ryan Rogers designed a hand-held model to demonstrate the concept of entropy for students.
'Doubly magic' rare isotope oxygen-28 can't overcome its neutron-rich instability
Isotopes -- atoms of a particular element that have different numbers of neutrons -- can be used for a variety of tasks, from tracking climate change to conducting medical research.Investigating rare isotopes, which have extreme neutron-to-proton imbalances and are often created in accelerator facilities, provides scientists with opportunities to test their theories of nuclear structure and to learn more about isotopes that have yet to be utilized in application.
