Furthermore, low-cost polymeric LDF have been also explored to produce SPR-based sensors [72]. In particular, by sputtering a gold nano-film on the PMMA-based LDF, the obtained bulk sensitivity ranges from 1000 to almost 3000 nm/RIU in the refractive index range from 1.332 to 1.392. In ...
and rewetting agents may be polymeric. Still another hydrophilic treatment includes bonding a second layer of wettable fibrous material to the polypropylene spunbond fabric such as a layer of wettable melt blown microfibers of polypropylene which are treated with a surfactant. Thus a hydrophilic treatm...
Prevent weeds between pavers or bricks.Keep your beautiful paver or brick driveway weed-free by filling the joins with polymeric sand. Cut down on labor costs.Avoid using pavers or bricks on oddly shaped driveways where they would have to be cut to fit. Get all necessary permits.Obtain a b...
Many point-of-care optical instruments use mass-produced, molded aspheric lenses to reduce the costs and complexity ofportable microscopy and spectroscopy systems. This work explores a method for producing low-cost polymeric aspheresand assesses the lens quality for various material types. Single lens...
Wear behaviour of polymeric materials reinforced with man-made fibres: A comprehensive review about fibre volume fraction influence on wear performance: in such severe environments because of their high strength to weight ratio, ease of production, high wear resistance and good corrosion/chemical resista...
A large number of industries use heavy metal cations to fix dyes in fabrication processes. Malachite green (MG) is used in many factories and in aquaculture production to treat parasites, and it has genotoxic and carcinogenic effects. Chromium is used to
However, compared with the traditional inorganic flocculants and organic polymeric flocculants, the high production cost is the main bottleneck that restricts the large-scale production and application of microbial flocculants. To reduce the produc- tion cost of microbial flocculant, a series of ...

[25] observed, in pressurized systems, that PAC fines usually increased the fouling of polymeric membranes while they did not affect ceramic membranes. In spite of the high potential of ceramic membranes in PAC/membrane systems, literature on practical uses is still limited, especially in real ...
