The ability to create biocompatible well-controlled membranes has been an area of great interest over the last few years, particularly for biosensor applications. The present study describes the fabrication and characterization of novel nanoporous micromachined membranes that exhibit selective permeability and low biofouling. Results indicate that such membranes can be fabricated with uniform p...

Biofouling causes huge economic loss and a recent global ban on organotin compounds as antifouling agents has increased the need for safe and effective antifouling compounds. Five structurally similar compounds were isolated from the crude extract of a marine Streptomyces strain obtained from deep-sea sediments. Antifouling activities of these five compounds and four other structurally-related ...

The capacity for secondary effluent filtration of hollow fiber polypropylene membranes grafted with several zwitterionic molecules and multi-walled carbon nanotubes was evaluated. In particular, all the modifications result in significant improvement of filtration performances. The anti-fouling properties of the membrane had been increased without damaging the membrane as observed from FTIR, TG...

Industrial wastewater treatment from cattle slaughterhouses traditionally use dissolved air floatation (DAF) to remove the high organic content of fat, oil and grease (FOG) from wastewaters and recover them for producing other products, including tallow, gelatine and food additives. Dissolved air floatation presents several operating difficulties including the large size, high energy use and od...

Membrane separation technologies have recently received much attention, from lab-scale studies to full-scale operations, in the forest industry. However, membrane fouling comprises a signifcant obstacle to their broad application. Thus, to ensure cost-effective operation of membrane separation processes, the improved elucidation of membrane fouling and establishment of e...

The application of anion exchange resins (AERs) has been limited by the critical problem of resin fouling, which increases the volume of the desorption concentrate and decreases treatment efficiency. To date, resin fouling has not been well studied and is poorly understood compared to membrane fouling. To reflect the resin fouling level, a resin fouling index (RFI) was established in this work ...

There is an increasing interest in developing innovative coatings and testing natural products with anti-fouling activity to substitute current highly toxic biocides that have a harmful impact on marine organisms. Bacillus licheniformis species shown different anti-biofilm activities vitro , but so far, its efficacy field trials has not been tested. For this purpose, the capacity of extracts B....

A bioinspired artificial compound eye (ACE) is fabricated by femtosecond laser wet etching, soft lithography, and polydimethylsiloxane (PDMS) swelling methods. The resultant ACE sample close-packed with more than 3000 high-quality microlenses on a spherical macrolens over its large viewing angle. trapped silicone oil in the PDMS endows device excellent water repellence anti-fogging ability besi...

Endoscopes are widely used in clinical settings. Gastric endoscopes particular useful for detecting early-stage gastric cancers and polyp removal. During removal or other simple surgical procedures, however, the spatter of blood bodily fluids resulting from excision affected areas can fog endoscope lens. Condensation caused by temperature differences between instrument interior exterior also af...
