In materials science, the surface wettability of a biomaterial can be measured using the surface water contact angle as an important characterization of its hydrophilicity or hydrophobicity. The technique has attracted remarkable ...
University of Calgary geoscientists have developed new technology that measures, at an extremely fine scale, the interaction between water and other fluids and rock from an unconventional oil reservoir.
