Liquid-crystalline phase transition in organophosphazenes
(John Wiley & Sons, Ltd., 1998-10)
Organophosphazenes with a similar mesogenic moiety were prepared and their mesogenicity was studied by differential scanning calorinetry (DSC) measurements and polarizing microsope observations. In cyclotriphosphazenes ...
Report On ‘The Sophomore Physical and Inorganic Courses’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
In this workshop, Mark M. Banaszak-Holl and M. David Curtis took turns elaborating on the recent changes and evolution of The University of Michigan’s introductory inorganic chemistry course, in light of an initial switch ...
Electrostatic model for infrared intensities in a spectroscopically determined molecular mechanics force field
(John Wiley & Sons, Inc., 1998-05)
A new electrostatic model for the calculation of infrared intensities in molecular mechanics and molecular dynamics is presented. The model is based on atomic charges, atomic charge fluxes, and internal coordinate dipoles ...
Report On ‘Integrating Materials Science into the Chemistry Curriculum’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
Working on the premise that materials science is justifiably an appropriate place to begin teaching chemistry, George Lisensky and Dean Campbell demonstrated in their workshop a series of introductory chemistry laboratory ...
Pt/MCM-41 catalyst for selective catalytic reduction of nitric oxide with hydrocarbons in the presence of excess oxygen
(Kluwer Academic Publishers-Plenum Publishers; Kluwer Academic Publishers ; Springer Science+Business Media, 1998-03)
First results are reported on the use of MCM-41 mesoporous molecular sieve as the support for Pt for the selective catalytic reduction of NO by hydrocarbons in the presence of O 2 . MCM-41 provided the highest specific NO ...
Report On ‘Planning And Implementing Curriculum Change in Chemistry: A Case Study in Creating a Blended General/Organic Course Sequence’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
A new curriculum involving a blended general and organic chemistry course is being introduced at San Jose State University this fall by Stephen Branz and Maureen Scharberg. They shared their experiences in creating this ...
Report On ‘The Penn State Resource Center: A Faculty Vision Becomes Reality’
(Springer-Verlag; Springer-Verlag New York, Inc., 1998-02)
In this workshop, Peter Jurs and Robert Minard presented a concise, easily applied formula for improving the overall quality of the learning experience at a large state school through simple reading into student psychology. ...
Effect of inclusion of electron correlation in MM3 studies of cyclic conjugated compounds
(John Wiley & Sons, Inc., 1998-04-15)
Electron correlation at the MØller–Plesset second-order level was incorporated into the Π-system portion of MM3 calculations for several conformers of [10]annulene, [18]annulene, bicyclo[5.3.1]undecapentaene, and ...
Atomistic Simulation of Curvature Driven Grain Boundary Migration
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-02)
We present two dimensional molecular dynamics simulations of grain boundary migration using the half-loop bicrystal geometry in the experiments of Shvindlerman et al. We examine the dependence of steady-state grain boundary ...
Polyhedral oligomeric silsesquioxane(POSS)-based polymers
(John Wiley & Sons, Ltd., 1998-10)
A diverse and entirely new class of monomer and polymer technology based on polyhedral oligomeric silsesquioxane (POSS) reagents has been developed. POSS reagents are unique in that they are physically large (approx. 15 14° ...
