Ester basestock vaporisation from thin oil films

Stability and interface properties of thin cellulose ester films adsorbed from acetone and ethyl acetate solutions.

Stability and interface properties of cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) films adsorbed from acetone or ethyl acetate onto Si wafers have been investigated by means of contact angle measurements and atomic force microscopy (AFM). Surface energy (gamma(S)(total)) values determined for CAP adsorbed from acetone are larger than those from ethyl acetate. In the ...

Thin liquid films in improved oil recovery from low-salinity brine

a r t i c l e i n f o Keywords: Low-salinity Waterflood LSW Brine Double-layer Sandstone Carbonate Film Low-salinity waterflooding is a relatively new method for improved oil recovery that has generated much interest. It is generally believed that low-salinity brine alters the wettability of oil reservoir rocks towards a wetting state that is optimal for recovery. The mechanism(s) by which the ...

Electronegativity-dependent tin etching from thin films

Resonant terahertz generation from InN thin films.

Highly efficient conversion from ultrafast optical pulses to their terahertz (THz) counterparts has been achieved with InN thin films. An average THz output power as high as 0.931 microW has been obtained for an average pump power of 1 W, corresponding to a normalized conversion efficiency of 190% mm(-2). Based on our measured dependences of the THz output power on pump polarization, incident a...

Computing robust basestock levels

In this paper we develop procedures for setting the basestock levels for a buffer in a supply chain subject to uncertainty in the demands. Our work is motivated by experience with an industrial partner in the electronics industry who was subject to the following difficulties: short product cycles, a complex supply chain with multiple suppliers and long production leadtimes, and a very competiti...
