[Innovation] - Codex International fully committed to "Lead free materials”

The RoHS concept (Restriction of the use of certain Hazardous Substances) since 2006, requires that many electrical and electronic equipment must no longer contain a concentration by atomic weight of more than 0.1% of Pb, Me, Cr (hexavalent) etc., because of their danger to the environment.

Codex International, in partnership with the UPHF in Valenciennes, is developing a range of lead-free piezoelectric targets: BNT-BT, KNN, NBT, etc., with performances comparable or even superior to PZT targets.

The objective is to develop reliable process for manufacturing marketable ceramic targets of NBT, NBT-BT and KNN, with a relative density > 90%, with controlled stoichiometry and while avoiding the volatility of alkalis.

[Nano-Technology] – New materials could enable longer-lasting implantable batteries 24 novembre 2022

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers.
