a key-coded plugging: To avoid mistakes when replacing modules, the bus units and modules have a "lock and key" coding system. Therefore, it is impossible to plug-in the wrong type of module 钥匙被编码的塞住: 要避免差错,当替换模块时,公共汽车单位和模块有一把“锁并且锁上”编码制...
This standard provides product specifications for Nano filtration membrane elements for industrial and similar purposes (here in after referred to as Nano filtration membrane elements). We have 3 types of NF membrane, operational purposes are also different, ...

Analytical tools such as elemental analyses using microanalyses, specific UV absorbance, solid-state cross-polarization magic angle spinning (CPMAS) 13C-NMR, high pressure size exclusion (HPSEC) chromatography, HPLC system and acid/base titration for characterizing NOM fractions and contact angle, ...
The fabrication process can be explained thermodynamically by the ternary phase system (i.e., a polymer–solvent–non-solvent system) [66]. The final morphology of the HF membrane can be controlled by several parameters, such as the concentration of dope solution and bore fluid, dope flow ...
The membrane hydrophilicity was confirmed using a video contact angle system (DSA-20, Germany) with the sessile drop method. 2.4. Separation Performances of TFN-Ag Membranes The NF performance of the membranes was investigated with a lab-made cross-flow membrane filtration apparatus at 25 °C....
The exceptional water stability, high adsorption capacity, and well-defined structure make COFs promising candidates for storing amine monomers, thus making them suitable as interlayer materials. For example, Wu et al. utilized [84] a PDA-COF interlayer to mediate IP, resulting in ultra-thin ...
