· Rapid Response Mechanism – Information for Applicants. The SAFE ENGAGE Project has established a Rapid Response mechanism to support advocates, experts, and decisionmakers in their efforts to advance evidence-based policy dialogue and expand access to safe abortion. This mechanism is intended to fill gaps in applicants’ capacity to create effective communication materials, develop and conduct analyses of existing data, and generally build applicants’ policy communication PRB strives to attract and publish high quality authoritative papers that should stand the test of time. PRB publishes papers in two formats: Regular Articles with no length limit, well suited for a thorough exposition of the research, and Rapid Communications, short letter-size papers for speedy publication of particularly important results. PRB’s criteria for publication have remained the same: papers should The American Physical Society (APS) PR series are all good, it is a century-old journal, classic classics, many Nobel papers are produced here, in this respectMore cattle than science, blogger.comgh the impact factor is mostly not high, it is because the published base is blogger.com them, Rapid Communications is comparable to blogger.comally, a more reasonable quantitative comparison: 1 PRL = 2 Rapid Comunications = 5 PRB

Temperature-dependent photoluminescence spectra of a range of semiconductor nanocrystals are presented which reveal an unanticipated thermodynamic relationship between the core excitonic states and the surface of the nanocrystal.
These results challenge prb rapid communication widely held view of the surface emission arising from an energetically broad distribution of midgap prb rapid communication states at the surface.
We show that a simpler model based on semiclassical electron transfer and invoking only a single surface state uniquely describes all observables.
Jonathan MooneyMichael M. KrauseJonathan I, prb rapid communication. COVID has impacted many prb rapid communication and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.
We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy. Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals.
To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions, prb rapid communication. Learn about our response to COVIDincluding freely available research and expanded remote access support.

The core PL is at higher energies whereas the surface PL is broader and redshifted. Integrated areas of the core and surface line-shape bands for CdSe c and CdS d showing the turnover points in surface emission.
Figure 2 Three models for core and surface emission from NCs. The standard energy-level picture of surface PL invokes a distribution of deep traps shown in the exciton representation a.
Due the depth of these traps, the relative PL spectra would exhibit no temperature dependence b. Prb rapid communication configuration coordinate picture using classical electron transfer ET theory to describe thermally activated population transfer from the core to the surface c.
The simulated spectra would show temperature dependence, prb rapid communication, but with little broadening and redshifting d, prb rapid communication. A minimal configuration coordinate picture using a semiclassical ET theory e. The solid line represents the classical prb rapid communication and the dashed lines represent the quantum mode, with displacements implicit.
The small free-energy difference along the classical bath coordinate gives rise to the temperature dependence of the surface PL, whereas the large coupling to the quantum phonon modes gives rise to the broadening and redshifting f. Figure 3 Integrated areas of the surface and core PL as a function of temperature a. The deep-trap model grey dashed line fails at all temperatures, the classical ET model fails at low temperatures grey linewhereas the semiclassical ET model black line uniquely reproduces the data at all temperatures.
Comparison of experimental and simulated spectra at various temperatures for CdSe b and CdS c. The semiclassical ET model predicts the relation between the redshift δ E and the linewidth of the surface PL Δ E d, prb rapid communication.
