After some minor pieces of theoretical study that I worked on, a student in my statistical mechanics class brought to my attention a problem in polyelectrolytes.

Polytechnique is a school whose multidisciplinary, very high scientific level curriculum is invaluable.
The science of semiconducting and metallic polymers is inherently interdisciplinary; it falls at the intersection of chemistry and physics.
If poly A is added to poly U, to form a double or triple helix, the combination is inactive.
Estimates of the ionic mobilities vary over a considerable range; but in any event, the positive ionic defect is much more mobile in the solid than in the liquid, and its mobility varies very little with the temperature.
In spite of the evidence for the disorder-induced M-I transition as inferred from the transport and optical measurements, the metallic state of conjugated polymers has been a subject of controversy.
All vinyl polymers may be regarded as built from monomeric units containing a tertiary carbon atom.
If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be expected that either helices of the same sense, or, in equal ratio, helices of opposite sense are represented in the lattice.
There are not too many people who are polymathic these days.
Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.
The thermodynamic properties of electrolyte solutions can be determined from the measurements of the voltage between electrodes reversible to both ions.
