Inputs of disinfection by-products to the marine environment from various industrial activities: Comparison to natural production

Urs von Gunten, Jin Jiang

Oxidative treatment of seawater in coastal and shipboard installations is applied to control biofouling and/or minimize the input of noxious or invasive species into the marine environment. This treatment allows a safe and efficient operation of industrial ...

Colloidal transport and deposition through dense vegetation

David Andrew Barry, Li Chen

The effectiveness of submerged synthetic aquatic vegetation on removal of colloids from flowing water was investigated to explore retention of particulate nonpoint source pollutants in aquatic systems. In colloid transport experiments, the deposition rate ...

Removal of trace organic contaminants from wastewater by superfine powdered activated carbon (SPAC) is neither affected by SPAC dispersal nor coagulation

Tamar Kohn, Florence Bonvin, Loïc Decrey

Powdered activated carbon (PAC) is increasingly used as tertiary treatment for the removal of trace organic contaminants (TrOCs) from wastewater (WW). To enhance the sorption kinetics and capacity, the PAC particles can be milled down to super fine powdere ...

Construction of MOF/Polymer Composites for Metal Ion Capture

Daniel Teav Sun

Metal ion capture is of environmental and economic significance. The industrial revolutions have discharged increasing amounts of heavy and precious metals into complex water sources. The key is that these types of metal ions tend to be at trace amounts in ...

Monitoring particulate fouling of North Sea water with SDI and new ASTM MFI0.45 test

Margot Ninon Lauren Olive

For assessing the particulate fouling of water, the modified fouling index (MFI0.45) is a superior test to the silt density index (SDI). There is a need to compare both tests in terms of sensitivity, how they are affected by the filter material and the typ ...

Cleaning strategy for carbon-based electrodes: Long-term propofol monitoring in human serum

Giovanni De Micheli, Giovanni Boero, Irene Taurino, Francesca Stradolini, Tugba Kilic

In this work, we present a novel electrochemical cleaning procedure for long-term electrochemical monitoring of propofol by using boron-doped diamond (BDD) and pencil graphite electrode (PGE). Propofol is an anesthetic that is widely used for long-lasting ...

Atomic aluminum content (x) effect on fretting-corrosion of Ti1-xAlxN coatings for orthopedic applications

Stefano Mischler

Normal micro-movements at the bone-implant interface originate fretting-corrosion processes, thus releasing wear debris from the bone and metallic devices and compromising the fixability of the implant. Titanium aluminum nitride (Ti1-xAlxN) coatings have b ...

Thermal Response of Multi-Microchannel Evaporators During Flow Boiling of Refrigerants Under Transient Heat Loads With Flow Visualization

John Richard Thome, Navid Borhani, Houxue Huang

Multi-microchannel evaporators with flow boiling, used for cooling high heat flux devices, usually experience transient heat loads in practical applications. These transient processes may cause failure of devices due to a thermal excursion or poor local co ...

Critical Heat Flux of R134a and R245fa Inside Small-Diameter Tubes

John Richard Thome, Sylwia Szczukiewicz, Cristiano Bigonha Tibiriça

This article presents new experimental critical heat flux results under saturated flow boiling conditions for a macro/microscale tube. The data were obtained in a horizontal 2.20-mm inside diameter stainless-steel tube with heating lengths of 361 and 154 m ...

Modeling of facade leaching in urban catchments

David Andrew Barry, Luca Rossi, Sylvain Coutu, Dario Del Giudice

Building facades are protected from microbial attack by incorporation of biocides within them. Flow over facades leaches these biocides and transports them to the urban environment. A parsimonious water quantity/quality model applicable for engineered urba ...

Effect of inclined jet screen on turbidity current

Anton Schleiss, Giovanni De Cesare, Christoph Oehy

The sustainable use of reservoirs for irrigation, flood protection, water supply and hydropower may be endangered due to unavoidable reservoir sedimentation. Turbidity currents are the main process for the transport and deposit of sediments in reservoirs, ...

Design of a high-throughput device for screening surface modification protocols

Karl Gademann

The development of new high performance, ultra-thin organic coatings requires a strategy that has to consider a large number of surface treatment variables such as binding moieties, substrate, and adsorption conditions (e.g. temperature, solvent, concentra ...

A facile strategy for the modification of polyethylene substrates with non-fouling, bioactive poly(poly(ethylene glycol) methacrylate) brushes

Jeffrey Alan Hubbell, Harm-Anton Klok

This manuscript reports a facile strategy for the modification of polyethylene, a widely used biomaterial, with a thin non-biofouling coating that can act as a platform to introduce biochemical cues to control and direct, e.g., cell adhesion and proliferat ...

Characterization of the mechanism of action of spin-filters for animal cell perfusion cultures

Florentina Vallez

The growing demand for high levels of recombinant proteins of medical and pharmaceutical interest stimulates the development of cell bioprocess technology. Spin-filter technology is employed in order to reach high levels of such compounds. The aim of this ...

Simulation of CO2 concentrations, temperature, and stratification in Lake Nyos for different degassing scenarios

Alfred Johny Wüest

[ 1] A large gas cloud erupted unexpectedly in 1986 from Lake Nyos, the larger of the two Cameroonian "Killer Lakes,'' with devastating consequences. Regular monitoring subsequently revealed that the deep water of the lake was gradually recharged with CO2. ...
