Devolatilization of polymer resins
Commercial silicon resin was devolatilized by vacuum distillation, cured at room temperature and tested favorably for outgassing criteria. Applications of the devolatilized resin are potting compounds and conformal coatings
Coherent States and Geometric Phases in Calogero-Sutherland Model
Exact coherent states in the Calogero-Sutherland models (of time-dependent
parameters) which describe identical harmonic oscillators interacting through
inverse-square potentials are constructed, in terms of the classical solutions
of a harmonic oscillator. For quasi-periodic coherent states of the
time-periodic systems, geometric phases are evaluated. For the
Calogero-Sutherland model, the phase is calculated for a general coherent
state. The phases for other models are also considered.Comment: To appear in the Int. J. Mod. Phys.
