An accelerated electromigration life‐test method has been developed to evaluate the large electromigration resistance of Cu interconnects in a very short period of test time. The essence of the acceleration technique employed here is to use stress current more than 10 7 A/cm 2 and to utilize the self‐heating of the te…

Phase equilibria in block copolymer (AB) + homopolymer (A) blends are considered theoretically in the strong segregation limit. The effect of homopolymer molecular weight is analyzed. In particular, the following are shown: (i) Long enough A-homopolymer chains (N(h) much greater than N(hc)) are incompatible with stret…

Abstract The self‐consistent method and finite element simulations have been used to estimate the permeability of an aligned fiber bundle. The self‐consistent method gives out formulas for both longitudinal and transverse permeabilities as functions of the fiber volume fraction. The finite element simulation presents…

Wheat starch granules and poly-(beta-hydroxybutyrate-co-beta-hydroxyvalerate) [P(HB-co-HV), (19.1 mol% HV)] were blended at 160 degrees C. Increasing the starch content from 0 to 50% (wt/wt) decreased the tensile strength of P(HB-co-HV) from 18 MPa to 8 MPa and diminished flexibility as Young's modulus increased from…

An unusual two-dimensional mesh of CuII ions is found in complex 1(see picture); the metal atoms are bridged by oxalato (ox) and bipyrimidine (bpym) ligands to form ringshaped hexamers. Variable-temperature magnetic susceptibility measurements indicate that antiferromagnetic coupling between the Cu atoms occurs.

Contrary to the traditional view, unnotched direct tension test specimens of quasi‐brittle materials that exhibit post‐peak strain softening do not deform symmetrically. After passing the peak load, the equilibrium path bifurcates and the secondary postbifurcation branch represents flexing to the side. The bifurcation…
