Abstract: Disclosed are a process and an apparatus for improving tobacco raw material. The process mainly comprises performing an extraction from at least one of tobacco leafs, tobacco flakes, tobacco powder, stalks and cut stems by mixed solvents, conducting a solid-liquid separation for the tobacco raw material, applying the extract liquor of tobacco leaves, flakes and cuts for manufacturing tobacco extract and that of stalks and cut stems for manufacturing fertilizer, diluting and mixing a given amount of tobacco aqueous extract and ethanol extract and removing harmful components so as to get feed liquid, backfilling the feed liquid to the tobacco raw material, and drying the tobacco raw material to a certain dryness to obtain the products. The apparatus is a system composed of a plurality of interconnected independent devices such as extractor, solid-liquid separator, a feed liquid backfiller, etc.

Abstract: A method of producing an improved cell growth surface and cell attachment surface. According to the present invention, a polymer article is molded at temperature in excess of 550° F. at the injection tip. After allowing the part to cool, a stream of plasma comprised of activated gaseous species generated by a microwave source is imparted on the article. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion superior to those of untreated polymer or polymer treated by other methods.

Abstract: A method for producing multiphase particle-reinforced metal matrix composites is provided. The method is characterized by the combination of an in-situ reaction process under an external electromagnetic field and an in-situ crystallization process under an external electromagnetic field. A traveling wave magnetic field or a rotating magnetic field is employed during the in-situ reaction process, and a rotating magnetic field or a high frequency magnetic field is employed during the in-situ crystallization process. Said method can obtain homogeneous, gradient enhanced or surface reinforced composite materials.

Abstract: Disclosed is a cell culture article including: a substrate; a tie-layer attached to at least the substrate; and a bio-compatible layer attached to at least the tie layer, the bio-compatible layer having been obtained from surface oxidation of a polymer layer. Also disclosed are methods for making the cell culture article and methods for performing an assay of a ligand with the article.

Abstract: A product exhibiting an improved cell growth surface and cell attachment. According to the present invention, a stream of plasma is comprised of activated gaseous species generated by a microwave source. This stream is directed at the surface of a polymer substrate in a controlled fashion such that the surface is imparted with attributes for cell adhesion far superior to that of untreated polymer or polymer treated by other methods.

Abstract: A method is described herein for making a multiwell plate that is used for assaying samples and is made from a plastic upper plate which forms the sidewalls of one or more wells and a glass lower plate which forms the bottom walls of the wells. The plastic upper plate and glass lower plate are attached and bound to one another by an enhanced adhesive. The enhanced adhesive includes an adhesive mixed with an additive that interacts with the adhesive, the plastic upper plate and the glass bottom plate in a manner that strengthens a bond between the plastic upper plate and the glass lower plate.
