Lead-free solder alloys have been around for as ... which is likely to be dissimilar between different materials. The tensile strength of the joint then determines at which point the resulting ...

“The new ferroelectric material – which is grown in the lab from cesium germanium tribromide (CsGeBr 3 or CGB) – opens the door to an easier approach to making solar cell devices,” they said.

Researchers from Tsinghua University, the Beijing Institute of Technology, the University of Wollongong (Australia), and the ...

Liu and Ren think they can explain how the phase behaviour in such systems generally produces a smaller piezoelectric response in lead-free materials, but also how it might be tuned to circumvent ...

The U.S. has adopted a much stricter stance on lead in the past 60 years, regulating the acceptable amount that’s in so many ...
