We present an experimental study on the adsorption behaviour of Intan-100, a nonionic surfactant, at the bitumen/water interface when the density difference between the two phases is increased by diluting the crude oil with 10% Xylene by weight or using heavy water (Deuterium Oxide) as the aqueous phase. Their equilibrium interfacial tension, surface excess and critical micelle concentration of...

Vanadium pentoxide poisoning has been described in men working in plants processing vanadium ore by Symanski (1939) and Sjoberg (1950), and twice (Wyers, 1946; Williams, 1952) in men exposed to the soot of fuel oil burned in boilers. It does not, however, appear to have been described before in men who work on gas turbines. Since these may become much more common in the future as sources of pow...

The routine surveillance of oil spills in major ports is important. However, existing techniques and sensors are unable to trace oil and micron-thin oil films on the surface of seawater. Therefore, we designed and studied a coastal-mounted sensor, using ultraviolet-induced fluorescence and fluorescence-filter systems (FFSs), to monitor oil spills and overcome the disadvantages of traditional su...
