摘要:
An article includes (a) a glass substrate having a modified surface that comprises a glass surface and a layer of nanoscale inorganic oxide particles disposed in contact with and bound to at least a portion of the glass surface, and (b) a polymer layer disposed in contact with and bound to the modified glass surface. A method for improving the hydrolytic stability of an interface of a glass surface and a polymer surface, includes the step of, prior to forming the interface of the glass surface and the polymer surface, treating at least a portion of the glass surface with nanoscale inorganic oxide particles to modify the glass surface by depositing a quantity of such particles on the portion of the surface.
摘要:
A method of decomposing stubble, which is crop residue left on the ground, and a composition for treating the stubble are disclosed. The method comprises treating the stubble with the composition comprising a) polysaccharide-degrading enzyme; b) wetting agent; and, optionally, c) water and allowing the treated stubble to remain on the ground and decompose.

摘要:
Disclosed are methods and systems for transferring dry or semi-dry nanoparticles onto a substrate. In one embodiment, this includes the steps of providing a roller comprising an elastomeric stamp; transferring nanoparticles in a dry or semi-dry state, and which contact the surface of a donor substrate, from the donor substrate onto the elastomeric stamp; and depositing the dry or semi-dry nanoparticles from the elastomeric stamp onto a receiver substrate by rolling the elastomeric stamp onto the receiver substrate. The substrate, in other embodiments, can have a relief structure.
