摘要： A method of coating a substrate comprises immersing a surface portion of a substrate in a liquid or supercritical first phase. The first phase comprises carbon dioxide and a coating component such as a polymer. The substrate is then withdrawn from the first phase into a distinct second phase such as a gas atmosphere so that the coating component is deposited on said surface portion. The withdrawal step is followed by separating the carbon dioxide from the coating component (e.g., by evaporation, venting, heating, etc.) so that the coating component is retained as a coating layer formed on the surface portion. Apparatus for carrying out the method by free meniscus coating, or employing a metering element such as a knife, blade, or roll, are also disclosed.
摘要翻译：涂覆基材的方法包括将基材的表面部分浸入液体或超临界第一相中。第一相包括二氧化碳和涂料组分如聚合物。然后将衬底从第一相中排出到不同的第二相，例如气体气氛中，使得涂层组分沉积在所述表面部分上。撤回步骤之后是将二氧化碳与涂料组分分离（例如，通过蒸发，排气，加热等），使得涂料组分作为形成在表面部分上的涂层而被保留。还公开了通过自由弯液面涂覆或采用诸如刀，刀片或辊的计量元件来执行该方法的装置。

摘要： A method for the enzymatic production of a desired product in a liquid or supercritical carbon dioxide fluid. The method comprises: (a) providing a reaction mixture comprising at least one reaction substrate and a crosslinked enzyme crystal catalyst in a liquid or supercritical carbon dioxide fluid; and (b) reacting said substrate with said crosslinked enzyme crystal catalyst in said carbon dioxide fluid to produce said product. The reacting step is typically followed by the step of (c) separating the product from said reaction mixture. The crosslinked enzyme crystal catalyst preferably comprises an enzyme crystal crosslinked with a multifunctional crosslinking agent, said crosslinked enzyme crystal having resistance to exogeneous proteolysis, such that the crosslinked enzyme crystal retains at least about 80 percent of its initial activity after incubation for three hours in the presence of a concentration of Pronase™ protease that causes the soluble uncrosslinked form of the enzyme that is crystallized to form said enzyme crystal that is crosslinked to lose at least about 80 percent of its initial activity under the same conditions. Reaction mixtures useful for carrying out the foregoing method and product mixtures produced by the foregoing method are also disclosed.
