摘要： Nanoparticles and compositions thereof are provided for detecting and/or preventing food spoilage. Methods of making the nanoparticles and compositions, and methods of using the nanoparticles and compositions, e.g. in food packaging, are also provided. The nanoparticles can have a hydrophobic core containing a hydrophobic active agent, e.g. a hydrophobic dye and/or an antimicrobial agent, for detecting and/or preventing food spoilage. The nanoparticles can also have a copolymer of a hydrophobic polymer repeat unit, e.g. styrene or lactic acid, and a pH responsive dendrimer repeat unit. The pH responsive dendrimer repeat unit can have a pH responsive amine core having a plurality of branched acrylate arms extending therefrom. The nanoparticles can be chemically stable at neutral pH, and then release the hydrophobic active agent at a pH range indicative of food spoilage. By releasing the hydrophobic dye and/or antimicrobial agent, the nanoparticles can detect and/or inhibit food spoilage.
摘要翻译：提供纳米颗粒及其组合物用于检测和/或防止食物变质。制备纳米颗粒和组合物的方法，以及使用纳米颗粒和组合物的方法，例如，也提供食品包装。纳米颗粒可以具有含有疏水活性剂的疏水性核心，例如，疏水性染料和/或抗微生物剂，用于检测和/或防止食品腐败。纳米颗粒还可以具有疏水性聚合物重复单元的共聚物，例如。苯乙烯或乳酸，以及pH响应性树枝状聚合物重复单元。 pH响应树枝状聚合物重复单元可以具有pH响应性胺芯，其具有从其延伸的多个支化丙烯酸酯臂。纳米颗粒可在中性pH下化学稳定，然后在指示食物腐败的pH范围内释放疏水活性剂。通过释放疏水性染料和/或抗微生物剂，纳米颗粒可以检测和/或抑制食物变质。

摘要： The present disclosure provides for compositions, slow-release fertilizer composition, methods of making these compositions, and the like. The present disclosure can be advantageous in some instances since it can achieve multiple goals, where in one aspect, the 5 modified lignin is used to prepare materials with strong adsorption capacity to the heavy metals, and then the material is used to coat fertilizer to prepare controlled-release fertilizer. The application of embodiments of the coated fertilizer in soil not only control the release of nutrients and improve the fertilizer use efficiency, but also effectively adsorb heavy metals in soil and repair the polluted soil.

摘要： The present disclosure provides for methods for depolymerizing lignin to produce other useful products. For example, low molecular weight aromatic and aliphatic hydrocarbons ( e.g ., hydrocarbons having 8 to 20 carbon atoms (C8 to C20 hydrocarbons)) as well as oil products can be produced using methods of the present disclosure. The method can include treatment of the lignin using a catalyst composition, where the catalyst composition comprises a persulfate salt and a transition metal catalyst.
