摘要:
A method for depositing a metal containing material onto a porous substrate, the method comprises forming a seed coating on the substrate, wherein the seed coating at least partially covers the substrate, the seed coating being substantially free of precious metal and applying a metal containing material to the seed coating, wherein the surface area of the substrate is greater than 0.02 m 2 /cc, as determined prior to coating the substrate. Non-porous substrates may also be coated using a similar process.

Coated diamond particles have solid diamond cores and at least one graphene layer. Methods of forming coated diamond particles include coating diamond particles with a charged species and coating the diamond particles with a graphene layer. A composition includes a substance and a plurality of coated diamond particles dispersed within the substance. An intermediate structure includes a hard polycrystalline material comprising a first plurality of diamond particles and a second plurality of diamond particles. The first plurality of diamond particles and the second plurality of diamond particles are interspersed. A method of forming a polycrystalline compact includes catalyzing the formation of inter-granular bonds between adjacent particles of a plurality of diamond particles having at least one graphene layer.

Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross- linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with 'easy-open' end closures.

摘要:
An apparatus and method for producing a coated analytic substrate using a compact and portable automated instrument located in the laboratory setting at the point of use which can consistently produce one or a plurality of coated analytic substrates “on demand” for using the analytic substrate immediately after coating, preferably without a step of rinsing the coated analytic substrate before use. The apparatus preferably uses applicator cartridges having a reservoir containing the coating compositions used to form the coatings. Preferably the cartridges are removable and interchangeable to facilitate the production of individual analytic substrates having different coatings or different coating patterns. These coated analytic substrates have superior specimen adhesion characteristics due to the improved quality of the coatings applied by the coating apparatus and due to the quickness with which the coated analytic substrates can be used in the lab after production.
摘要:
The invention concerns a method of coating preferably electrically non-conducting surfaces with preferably electrically conducting finely particulate materials by dipping the article to be coated into the following baths in succession: a) an aqueous solution of polymers (pre-dip solution), b) an aqueous dispersion of the finely particulate material, the dispersion also containing surfactants to prevent sedimentation and a salt to ensure the controlled destabilization of the dispersion. Coating with electrically conducting particles, such as graphite or carbon black, can be carried out in preparation for the galvanic deposition of a metal.
