Metals In Metal Salts: A Copper Mirror Demonstration, Robert D. Pike
Metals In Metal Salts: A Copper Mirror Demonstration, Robert D. Pike
Arts & Sciences Articles
A simple lecture demonstration is described to show the latent presence of metal atoms in a metal salt. Copper(II) formate tetrahydrate is heated in a round-bottom flask forming a high-quality copper mirror.
Reversible Luminescent Reaction Of Amines With Copper(I) Cyanide, Amanda N. Ley, Lars E. Dunaway, Timothy P. Brewster, Matthew D. Dembo, Et Al., Robert D. Pike
Reversible Luminescent Reaction Of Amines With Copper(I) Cyanide, Amanda N. Ley, Lars E. Dunaway, Timothy P. Brewster, Matthew D. Dembo, Et Al., Robert D. Pike
Arts & Sciences Articles
Copper(I) cyanide exposed to various liquid or vapor-phase amines (L) at ambient temperature produces a variety of visible photoluminescence colors via reversible formation of amine adducts. The adducts show phase matches to authentic (CuCN)Ln, n = 0.75–2.0, produced by heating CuCN with liquid amine.

Dynamics Of Electron Wave Propagation In Photoionization Microscopy: I. Semiclassical Open-Orbit Theory, L. B. Zhao, John B. Delos
Arts & Sciences Articles
This is the first of two papers that develop theories and numerical methods for photoionization microscopy of hydrogen atoms in strong electric fields, in semiclassical and quantum-mechanical frameworks, respectively. In this paper, semiclassical open-orbit theory is presented to describe the propagation of outgoing electron waves to macroscopic distances. Spatial distributions of electron probability densities and current densities are predicted. The open-orbit theory, based on an assumption that electron waves propagate along classical paths from a pointlike source to a detector, provides a clear and intuitive physical picture to interpret structures of observed geometrical interference patterns in photoionization microscopy. We calculate …
Does Prodan Possess An O-Tict Excited State? Synthesis And Properties Of Two Constrained Derivatives, Christopher J. Abelt
Does Prodan Possess An O-Tict Excited State? Synthesis And Properties Of Two Constrained Derivatives, Christopher J. Abelt
Arts & Sciences Articles
The synthesis and photophysical properties of 7-(dimethylamino)-3,4-dihydrophenanthren-1(2H)-one (7) and 3-(dimethylamino)-8,9,10,11-tetrahydro-7H-cyclohepta[a]naphthalen-7-one (8) are reported. These compounds possess a cycloalkanone substructure that controls the extent of twisting of the carbonyl group. The six-membered ring in 7 forces the carbonyl group to be coplanar with the naphthalene ring, whereas the seven-membered ring in 8 induces a significant twist. Both have the substructure of PRODAN (6-propionyl-2-(dimethylamino)naphthalene, 1). Comparing the photophysical behavior of these compounds with that of PRODAN and 2,2-dimethyl-1-(4-methyl-1,2,3,4-tetrahydrobenzo[f]quinolin-8-yl)propan-1-one (3) indicates that PRODAN likely emits from a PICT excited state rather than from an O-TICT excited state.
Effect Of Node-Degree Correlation On Synchronization Of Identical Pulse-Coupled Oscillators, M. Drew Lamar, Gregory D. Smith
Effect Of Node-Degree Correlation On Synchronization Of Identical Pulse-Coupled Oscillators, M. Drew Lamar, Gregory D. Smith
Arts & Sciences Articles
We explore the effect of correlations between the in and out degrees of random directed networks on the synchronization of identical pulse-coupled oscillators. Numerical experiments demonstrate that the proportion of initial conditions resulting in a globally synchronous state (prior to a large but finite time) is an increasing function of node-degree correlation. For those networks observed to globally synchronize, both the mean and standard deviation of time to synchronization are decreasing functions of node-degree correlation. Pulse-coupled oscillator networks with negatively correlated node degree often exhibit multiple coherent attracting states, with trajectories performing fast transitions between them. These effects of node-degree …
