Origin of the quantum shape effect

A Aydin, A Sisman - Physical Review E, 2023 - APS
The quantum size and shape effects are often considered difficult to distinguish from each
other because of their coexistence. Essentially, it is possible to separate them and focus …

Thermodynamic and structural evidence for reduced hydrogen bonding among water molecules near small hydrophobic solutes

J Kim, Y Tian, J Wu - The Journal of Physical Chemistry B, 2015 - ACS Publications
