A modified method to synthesize 3BCMU and to polymerize it by ultraviolet (UV) radiation is presented; the polymerization technique gave a maximum yield of 18%. Langmuir-Blodgett and spin coated films of UV/poly-3BCMU have been fabricated. Visible an

We show that a process based on sol–gel chemistry can produce silica glass microstructures which replicate the mold used up to at least the micron scale. This technology is characterized by the thermomechanical ideal isotropy of the intermediates p

We have observed nonlinear absorption in spin‐coated poly(4,6‐decadiyne‐1, 10‐diolbis {[(n‐butoxycarbonyl)methyl]urethane}) [poly(3BCMU)] polydiacetylene channel waveguides at different wavelengths in the near‐infrared. Intensity dependen

The authors show that the approach to equilibrium in non-linear-Hamiltonian systems exhibits strongly non-gaussian features (intermittency). The intensity of the phenomenon grows fainter until it vanishes near equilibrium. They present a heuristic in

Outer sphere electron transfer rates in polar media are analyzed for non‐Debye solvents whose dielectric function contains a few relaxation times (e.g., linear alcohols) or has a continuous distribution of relaxation times (e.g., the Cole–Davidso

A correlation function formulation, based on the Liouville equation for the density matrix, provides a microscopic theory for solvation dynamics and establishes a general fundamental connection between the calculation of rate processes and nonlinear

The Fermi-Pasta-Ulam model has been studied following the time evolution of the space Fourier spectrum through the numerical integration of the equations of motion for a system of 128 non-linearly coupled oscillators. One-mode and multimode excitatio

We present a quantum mechanical theory of the dynamics of a charge carrier or an electronic excitation in a condensed phase system, in which the solvent degrees of freedom that couple to the electronic excitation are characterized by a correlation ti
