摘要： A cleaning medium or formulation that contains a sporicidal composition is described. The composition includes about 0.1-20% weight/weight of a germinant agent, about 0.01-75% w/w of an antimicrobial agent, in terms of dry or wet total weight, and which is admixed with water to generate a solution with a pH of 3.5-9.5. The composition can help trigger the germination of spores, in particular C. difficile, and subsequently deactivate or kill the spores. A means of applying the cleaning formulation in a medium and process for cleaning are also described.

摘要： A method for forming a biodegradable polylactic acid suitable for use in fibers is provided. In one embodiment, for example, a polylactic acid is melt blended with an alcohol to initiate an alcoholysis reaction that results in a polylactic acid having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and polymer concentrations, catalysts, temperature, etc.), a modified polylactic acid may be achieved that has a molecular weight lower than the starting polylactic acid. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.

摘要： A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and also facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the aliphatic-aromatic copolyester may also be extruded with the thermoplastic starch at a temperature that is low enough to avoid substantial removal of the moisture found in the starch. Furthermore, the aliphatic-aromatic copolyester is also modified with an alcohol so that it contains one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a molecular weight that is relatively low. Such low molecular weight polymers have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.

摘要翻译： 提供由含有热塑性淀粉和脂肪族 - 芳香族共聚酯的热塑性组合物形成的纤维。 共聚酯增强了含淀粉纤维的强度，并且促进了淀粉熔融加工的能力。 由于其相对低的熔点，脂肪族 - 芳族共聚酯也可以在足够低的温度下与热塑性淀粉一起挤出，以避免显着除去在淀粉中发现的水分。 此外，脂族 - 芳族共聚酯也用醇改性，使得其含有一个或多个羟烷基或烷基端基。 通过选择性地控制醇解反应的条件（例如醇和共聚物浓度，温度等），所得改性的脂肪族 - 芳族共聚酯的分子量可以相对较低。 这种低分子量聚合物具有较高的熔体流动指数和较低的表观粘度的组合，其可用于各种各样的纤维形成应用中，例如在非织造纤维网的熔喷中。

摘要： This invention describes a general binding assay method to detect the presence and quantity of analyte in a sample. The method uses time-resolved up-converting fluorescence detection technique to provide highly sensitive detection without using expensive optical components such as band-pass optical filters. The method uses pulsed long wavelength light for excitation and time-delayed luminescence detection, resulting in little interferences from sample matrices. Furthermore, the usage of long wavelength excitation light requires simpler sample preparation and processing such as removal of red blood cells, which otherwise will significantly interfere with excitation efficiency of the luminescence probes.

摘要： Methods for adjusting the solubility of a botanical oil in water, along with the resulting modified botanical oil and related products (e.g., treatment compositions, wipes, absorbent articles, etc.) are provided. In one embodiment, the method includes reacting the botanical oil to form a reactive product (e.g., having a hydroxyl group); and attaching a hydrophilic end group (e.g., a carboxylic acid, a carboxylic acid salt, a sugar, etc.) on the reactive product to form a modified botanical oil. The modified botanical oil generally, in most embodiments, has a greater solubility in water than the botanical oil (e.g., a solubility in water of about 10 grams per 100 grams of water or greater, such as completely soluble in water). The botanical oil includes, in one particular embodiment, an essential oil, such as those essential oil that include at least one terpene compound.
