BNTBT KNN - Codex international

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.

[Thin Films] – How is CVD Used to Create Thin Films for Semiconductors? 1 novembre 2020

CVD is a well-known technique in the nanofabrication space known for being able to take a vaporized reactant and deposit it onto a surface to form a thin film. There are many thin films and nanomaterials which can be fabricated using CVD, with the most notable being graphene.

[Nano-technology] – Researchers design next-generation electrolytes for lithium batteries 1 octobre 2022

A team of researchers has discovered a new mechanism to stabilize the lithium metal electrode and electrolyte in lithium metal batteries. This new mechanism, which does not depend on the traditional kinetic approach, has potential to greatly enhance the energy density — the amount of energy stored relative to the weight or volume — of batteries.
