A phenyl and an azobenzenyl chromophore incorporating amino donors and cyanovinyl and nitro acceptors, with principal molecular moments held at 110C angles by propenoylpiperzine linkages, were synt
The effect of the dipole-dipole interaction on the magnetism of a two-dimensional lattice of spins coupled by isotropic short-range exchange interactions is investigated.
A remarkable manifestation of the quantum character of electrons in matter is offered by graphene, a single atomic layer of graphite.
We experimentally demonstrate 10-Gb/s operation of a reflective semiconductor optical amplifier (RSOA) for data transmission in passive optical networks, with optical power budgets of up to 28 dB.
Changes in the internal representation of a visual display during the first second after presentation are among the earliest phases of human cognition where memory mechanisms may be investigated.
We present new algorithms for computing the transitive closure of large database relations.
In connection with our studies of organonmetallic complexes of the 1,9-disubstituted-phenalene unit (1) we required access to compounds possessing a total of just two ionizable hydrogen atoms in th
In order tocope with the ever-growing Internet traffic, high-speed optical interconnects are becoming indispensable.
The effect of triplet sensitizers on the photoinitiated polymerization (cure) of a model acrylate monomer, isobornyl acrylate (IBOA), has been investigated.
The fraction of positrons which survive below the positronium (Ps) formation energy in a low density galactic environment can directly annihilate with bound electrons in the gas.
