摘要： The invention relates to the filtering of liquid samples, preferably in a laboratory environment, for example for collecting micro organisms from the liquid sample for subsequent testing. The invention provides a method for filtering a liquid sample which comprises providing a blank of a deformable sheet material and a filtration medium, deforming the blank to form a funnel extending above and about the filtration medium, introducing the liquid sample to be filtered into the so formed funnel, and filtering the liquid sample from the funnel through the filtration medium, for example to a downstream receptacle. The method is accordingly based on the concept that the funnel is not or at least not completely preformed but provided in a form of a blank of a deformable material sheet which is deformed so as to form the funnel at the point and time of use during filtration.

摘要： The invention comprises an environmentally benign method for the direct in situ preparation of copper nanoparticles (CuNPs) in paper by reducing sorbed copper ions with ascorbic acid. Copper nanoparticles were quickly formed in less than 10 minutes and were well distributed on the paper fiber surfaces. Paper sheets were characterized by x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, and atomic absorption spectroscopy. Antibacterial activity of the CuNP sheets was assessed for by passing Escherichia coli bacteria suspensions through the papers. The effluent was analyzed for viable bacteria and copper release. The CuNP papers with higher copper content showed a high bacteria reduction of log 8.8 for E. coli. The paper sheets containing copper nanoparticles were effective in inactivating the test bacteria as they passed through the paper. The copper levels released in the effluent water were below the recommended limit for copper in drinking water (1 ppm).
摘要翻译：本发明包括通过用抗坏血酸还原吸附的铜离子在纸中直接原位制备铜纳米颗粒（CuNP）的环境友好方法。铜纳米颗粒在不到10分钟内快速形成，并且在纸纤维表面上分布良好。纸片通过X射线衍射，扫描电子显微镜，能量色散X射线光谱和原子吸收光谱表征。通过将大肠杆菌细菌悬浮液通过纸张来评估CuNP片材的抗菌活性。分析流出物的活菌和铜释放。铜含量较高的CuNP纸显示出对大肠杆菌的log 8.8的细菌减少。含有铜纳米颗粒的纸片在通过纸时使试验细菌失活是有效的。废水中释放的铜含量低于饮用水中铜的推荐限值（1 ppm）。

摘要： A filter cartridge and filter for a water bottle is presented. The filter cartridge has a top member with an inwardly sloped exterior surface and at least one opening. The top member is removeably coupled with a bottom member to form an enclosure for housing a filter. The bottom member also has an opening or inlet to allow water to pass through the filter cartridge. The filter cartridge also has an outer rim with a seal (e.g., a sealing ring, etc.). The filter can comprise a frustoconical shaped portion.

摘要： A filter includes a housing having an inlet and an outlet. A filter core including a filter media is movably disposed within the housing with the inlet and the outlet in fluid communication with opposite sides of the core and a pressure responsive surface in fluid communication with said inlet. The filter also includes a valve supported on the filter core and moveable into a sealing position to prevent fluid from passing to the outlet when said core moves within said housing response to fluid pressure acting against said pressure responsive surface.
