The SCF electron density
map in the CuO2 layer of superconducting cuprates shown above is
important to understand experimental results in the 21st Century. To
read on computational chemistry go to: Int. J. Quantum Chemistry, 46, 55 (1993). The electron density above is shown
increasing from .005 electrons/bohr3 in the (CuO2)5O6-22 lamella
in the crystal field of the two dimensional superconductor YBa2Cu3O7
made up of 346 atoms and point charges. The CuO2-2
conduction layer of superconducting cuprates, the highest filled orbitals, are
mostly oxygen type. Click on the above reference to see how the electron
density changes as the energy levels fill up. Note that the highest filled
states are mostly overlapping diagonally adjacent O:2px, 2py
states. The conductivity as well as the orientation dependence of
photo-emission measurements can be explained by the direction of delocalized MO
orbitals in the highest filled states. This is still true in the year 2000. Other research maybe accessed from
menu below.
To read on X-Ray Absorption
Spectroscopy (XAS) at the Stanford Synchrotron Radiation Laboratory (SSRL) and
SJSU please look up published work on "Dynamic phenomena in layer
superconducting cuprate and organic metals", Superlattices and Microstructures,18, 197
(1995). The 21st Century finds us studying phase diagrams
on the non-metal to metal/superconducting transition as envisioned by N.F. Mott
(see Research Philosophy).
To read on Electron Spin
Resonance (ESR) at the SJSU educational/research facility please look up
published work on " Dynamic Phenomena In the Organic Metal (BEDT-TTF)3Ta2F11",
Mol. Cryst. Liq. Cryst. 284, 411 (1996). The use of
organic/metals superconductors is a very important topic of the 21st
Century. New Bruker EMX/ESR is used for teaching/research purposes.
To read on Critical
Phenomena see "Spin Exchange Term in the Solvent Equation of State Near
the Critical Point for Electron Transfer Reactions", see J.V. Acrivos, J. Solid State Chemistry, 150
April (2000). This is a very important topic for reactions in critical and
supercritical fluids (see Research Philosophy).
Spring 2000: Emerita
(01/21/00). Reduced SJSU laboratory facilities to DH17 from DH9, DH15A and
DH17. Continues to do research (with 6 students at SSRL, Stanford and ALS, LBL)
and teach seminar courses.
Information on special
lectures on Advanced Analytical Chemistry on modern topics (not found in
textbooks or regular curricula, see Teaching Philosophy and CHEM 159XAS and CHEM 159ESR). New
EMX Bruker spectrometer is used for this course.
