Salinity Effect on the Surfactant Critical Micelle Concentration through Surface Tension Measurement
One of the tertiary methods for enhanced oil recovery (EOR) is the injection of chemicals into oil reservoirs, and surface active agents (surfactants) are among the most used chemicals. Surfactants lead to increased oil production by decreasing interfacial tension (IFT) between oil and the injected water and to the wettability alteration of the oil reservoir rock. Since surfactants are predomin...
متن کاملEffect of Grain-Boundary Phase
Two types of hot-pressed silicon nitride, one having an amorphous grain-boundary phase (6 wt% yttria, 3 wt% alumina) and the other having a predominantly crystalline grain-boundary phase (8 wt% yttria, 1 wt% alumina), were tested on a split Hopkinson pressure bar with a momentum trap, such that, in each test, the sample was subjected to a single predefined stress pulse and then recovered withou...
متن کاملMicrofluidic sensor for dynamic surface tension measurement.
A novel microfluidic sensor for measuring dynamic gas-liquid interfacial tension is reported. The device consists of a microfluidic chip with a microchannel network and an optical detection system. The sample is introduced into a main channel, while air is injected through a T-junction. Owing to the fixed flow rate ratio used for the sensor, surface tension is the only parameter determining bub...
متن کاملNoncontact surface tension measurement by drop rotation
Validity of the surface tension measurement technique that was proposed by Elleman et al. was experimentally verified. The technique was based on Brown and Scriven’s work on the shape evolution of rotating drops. Molten tin and aluminum drops were levitated in high vacuum by the electrostatic levitator and rotated by applying a rotating magnetic field. This technique offers an alternative techn...
متن کاملFive-parameter grain boundary distribution in grain boundary engineered brass
We report the first application of a five-parameter determination of grain boundary types to grain boundary engineered alpha-brass. The most important findings were that the distribution of planes showed a prevalence of <110> tilt boundaries, especially asymmetric tilt types, and the presence of <111> twist boundaries. This distribution resulted from the low energy of these boundary types.
