'Supercritical Water' Density Effects on the Rate of Isopropanol Dehydration

January 1, 2001
Author(s)
V I. Anikeev, Jeffrey A. Manion, A Ermakova
A new experimental procedure for studying the kinetics and thermodynamics of chemical reactions in supercritical fluids-solvents was suggested. The kinetics and mechanism of the dehydration of 2-propanol in supercritical water in a closed reactor were

Polymer Mobility Near the Polymer/Solid Interface

May 6, 1999
Author(s)
Eric K. Lin, Wen-Li Wu, Sushil K. Satija, R Kolb
Neutron reflectometry is used to measure polymer mobility near an attractive solid surface over distances less than the bulk polymer radius of gyration, R g. Effective diffusion coefficients, D eff, are determined from the rates of interdiffusion between

Transient Phenoxyl Radicals: Formation and Properties in Aqueous Solutions

October 12, 2021
Author(s)
S Steenken, Pedatsur Neta
This chapter discusses the various methods of formation of phenoxyl radicals (oxidation of phenols by metal ions, by free radicals and radical cations, reaction of phenols with hydroxyl radicals, autoxidation of phenols, etc.) and the properties of

Quantum Dense Coding with Atomic Qubits

January 1, 2004
Author(s)
T Schaetz, Murray D. Barrett, Dietrich G. Leibfried, J Chiaverini, Joseph W. Britton, Wayne M. Itano, John D. Jost, Christopher Langer, David J. Wineland
We report the implementation of quantum dense coding on individual atomic qubits with the use of two trapped 9Be+ ions. The protocol is implemented with a complete Bell measurement that distinguishes the four operations used to encode two bits of classical

Experimental purification of two-atom entanglement

October 19, 2006
Author(s)
Rainer Reichle, Dietrich G. Leibfried, Emanuel H. Knill, Joseph W. Britton, Brad R. Blakestad, John D. Jost, C. Langer, R Ozeri, Signe Seidelin, David J. Wineland
Entanglement is one of the most counterintuitive features of quantum mechanics. It is a necessary resource for quantum communication and quantum information processing. Entanglement established between different locations enables private communication and
