“Nosonovsky blends surface science with machine learning to predict beach contamination”
Friction, wetting, mechanics, and related matters
Why some important papers are cited while others are not
Researchers generate new knowledge. In science, knowledge is formulated and distributed in the form of academic publications, usually, peer-reviewed journal articles. One of the questions constantly asked about publications and citations in the professional community is whether publications are a… Read More
