Abstract: The present invention relates to a particulate highly porous amorphous mesoporous magnesium carbonate material suitable for uptake of high amounts of oily substances, sebum or a beneficial agent or combinations of these and to topical and cosmetic compositions comprising such material. The particulate highly porous amorphous mesoporous magnesium carbonate material according to the invention has a total pore volume larger than 0.1 cm 3/g and is constituted of particles having a peak particle size at or below 35 ?m.

Abstract: A cutting tool has a substrate of cemented carbide including WC and a binder phase. The cutting tool has a gradient surface zone with a thickness of between 50-400 ?m having a binder phase gradient with the lowest binder phase content in the outermost part of the gradient surface zone and wherein the cutting tool also includes free graphite. The present disclosure also relates to a method of making a cutting tool according to the above. The cemented carbide body shows improved resistance towards chemical wear when used for machining non-ferrous alloys such as Ti-alloys and Ni-based alloys.

Abstract: The present invention relates to a getter material and a production method thereof. The method enables control of a sol-gel process so that a nanoparticle getter material with intrinsic nanoparticles in a size range from 10 nm to 1 ?m can be produced with accurate size control. The intrinsic nanoparticles of the getter material are composites of magnesium oxide and amorphous magnesium carbonate, substances that have properties that are highly interesting for getter applications. The composition ratio of magnesium oxide to magnesium carbonate may preferably be in the range from 5:95 to 50:50.
