Interesting@helloween There's a little bit more info about the fumed silica in the french version. BT says that this project will be in a third entity (HPQ polvere?) because he thinks that, like HPQ nano, a third party will be interested to join. He also said that the fumed silica project is similar to the QRR deal : HPQ pay 100% of the R&D and the revenue is splitted 90%/10% HPQ/PYR
