A novel film optical link module (FOLM) structure is proposed. A beveled cut process for the high-density surface normal waveguide couplers for FOLM is described. 250-/spl mu/m pitch cut walls of three different directions were demonstrated in polyim

Cis-trans isomerization of butenes in free-anion systems proceeds through the α-butene intermediate. Direct cis - and trans -transformation of crotyl anions does not occur. Reactions of crotyl anion and its ion pairs with proton-donor compounds in h

An excimeric state has been discovered in polyacenaphthylene (PA), resulting from intermolecular interaction of chromophoric groups. It is shown that dehydropolyacenaphthylene (DPA) contains a range of conjugated blocks of different length. The emiss

π-Allyl complexes of nickel induce stereospecific homopolymerization of cyclohexadiene-1,3 and 2,3-dimethylbutadiene with the formation of crystalline polymers. These polymers consist of 1,4-monomer units in cis -configuration for polycyclohexadiene

A study has been conducted of the relative reactivity of a series of dienes (butadiene, isoprene, 2,3-dimethylbutadiene, cyclohexadiene-1,3), as well as of butadiene and styrene, in copolymerization by various coordination catalyst systems based on t
