Sintered eutectoid P/M steel behaviour during cold upsetting
Cold upsetting experiments were carried out on sintered Fe-0.8%C steel preforms in order to evaluate the technical relationship that exist between the applied stresses against continuous deformation and densification.

Research on automatic spraying of single-walled carbon nanotubes and detection of spraying effects
Single-walled carbon nanotubes (SWNTs) have been introduced as compliant electrodes for dielectric elastomers (DEs) due to fault tolerance. To acquire a better electrostrictive strain and longer lifetime, it is essential to obtain a certain and uniform ...

Predicting band offset of lattice matched ZnO and BeCdO heterojunction from first principles
Using first-principles approach, we calculated the band gaps of wurtzite $ {\rm Be}_{1-x} $ Cd $ _x{\rm O} $ ternary alloy and the band offset of the lattice matched $ {\rm ZnO}/{\rm Be}_{0.44}{\rm Cd}_{0.56}{\rm O}[1\,1\,\overline {2}\,0 ...
