we report a pd-co (3:1)/graphene oxide (pd3co /go) catalyst through a one-step strategy. go is synthesized from graphite electrodes using ionic liquid-assisted electrochemical exfoliation. controllable go-supported pd3co electrocatalystis then was reduced by ethylene glycol as a stabilizing agent to prepare highly dispersed pdco nanoparticles on carbon graphene oxide to be used as oxygen reduct...

Cathode ray tube funnel glass is an environmentally problematic relict of old television sets. In particular, landfilling of this material is strongly discouraged because of its high lead content. However, recovery of this toxic lead could prevent its release into the environment and allow its reuse. In this research, lead was separated from the glass matrix by a chloride volatilization process...

The influence of cathode agitation on the residual stress of electroplated gold has been investigated. Using a custom-built plating cell, a periodic, reciprocating motion was applied to silicon substrates that were electroplated with soft gold. A commercially available gold sulfite solution was used to deposit the 0.6 lm thick gold films using a current density of 3.0 mA/cm and a bath temperatu...

This paper examines the rôle of letterforms as a means of communication, starting with hand-set metal type and mechanical typesetting in hot metal. Present-day techniques of phototypesetting, and of digital typesetting, via cathode-ray tube and laser machines, are also discussed. Careful attention is paid to the cultural impact of these techniques, with particular reference to traditional Frenc...
