Mussels are opportunistic macrofouling organisms that can attach to most immersed solid surfaces, leading to serious economic and ecological consequences for the maritime and aquaculture industries. We demonstrate that lubricant-infused coatings exhibit very low preferential mussel attachment and ultralow adhesive strengths under both controlled laboratory conditions and in marine field studies...

a 2-year period a tenacious film formed. Daily free passage of sponge rubber balls through the tubing only removed the loose surface biofouling layer and was inadequate as a countermeasure in both titanium and aluminum alloy tubes. Chlorination at 0.05, 0.07, and 0.10 mg liter-' for 1 h day'1 lowered biofouling rates. Only at 0.10 mg liter-' was chlorine adequate over a 1-year period to keep fi...

the surface properties of tio2-pvdf nanocomposite membranes were investigated by incorporating different chemically modified tio2 nanoparticles into the poly (vinylidene fluoride) (pvdf) matrix. the nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. the membrane surface morphologies were investigated by using sem and afm and related...

The biofouling affinity on different polymeric surfaces (PP, PSU, PET, PEEK) in comparison with SS 1.4301 was studied using the model bacterium E.coli K12 DSM 498. A test rig with seven identical chambers allowed investigations at different system conditions (throughputs, inclination of the heat transfer cell, etc.). The biofilm mass deposited on the polymer surfaces was several magnitudes smal...

Biofouling remains a key challenge for membrane-based water treatment systems. This study investigated the dispersal potential of the nitric oxide (NO) donor compound, PROLI NONOate, on single- and mixed-species biofilms formed by bacteria isolated from industrial membrane bioreactor and reverse osmosis (RO) membranes. The potential of PROLI NONOate to control RO membrane biofouling was also ex...

Root caries prevention has been a challenge for clinicians due to its special anatomical location, which favors the accumulation of dental plaque. Researchers are looking for anti-biofouling material to inhibit bacterial growth on exposed root surfaces. This study aimed to develop polydopamine-induced-polyethylene glycol (PEG) and to study its anti-biofouling effect against a multi-species cari...

Bacterial biofilms create a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes, and biodeterioration of the components of metallic and polymeric systems result in billions of dollars in losses each year. Product spoilage and possible risks to public health are also consequences of biofilm-mediated contamination. Fund...

The aims of this paper were to study the biofouling and biodeterioration of photos and maps stored at Historical Archive of the Museum of La Plata (HAMP), Argentine, and two repositories of the National Archive of Cuba Republic (NARC) and to carry out the physiological characterization of the isolated fungi and bacteria. The role of the environmental microbiota in the biofouling formation was a...

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...
