The invention relates to a novel metal mold having anti-adhesive properties comprising a base metal mold and an anti-adhesive layer comprising a fluorinated alkyl phosphoric acid derivative, or a fluorinated alkyl poly-phosphoric acid derivative, such as a phosphoric acid, phosphate or phosphate salt, a phosphonic acid, a phosphonate or phosphonate salt, or their respective oligomers. The base mold metal may be nickel, vanadium, aluminium, tantalum, niobium, zirconium, titanium, or their alloys.

The invention relates to a processes and compositions for preparing anti-reflective coatings.

An article for in-house use, preferably a picture frame or a show case, comprising a frame with an anti-reflective glass plate, the glass plate having on at least a part of at least one of its surfaces a light reflection reducing coating wherein the wherein the coating contains nano-size particles and a binder, the coating having an arithmetic average roughness of 2-50 nm, and having per reflective coated side a minimum reflection at a wavelength between 400 and 800 nm of about 2% of less.

This invention relates to magnetic nanosized particles having a glass surface. This invention also relates to methods for making them, as well as to suspensions thereof and their uses for the purification of DNA or RNA in particular in automated processes.
