Applying a force to certain supramolecular bonds may initially stabilize them, manifested by a lower dissociation rate. We show that this behavior, known as catch bonding and by now broadly reported in numerous biophysics bonds, is…

For the first time, an ab initio molecular dynamics simulation was performed to describe the C$_3$S/water interface. The simulation shows that oxides with favorable environment are protonated at first, creating very stable hydroxide groups.…

Correlations between the incoming partons in multiple hard scattering can affect both the event rate and kinematic distributions in the final state. In this talk, I discuss different types of correlations relevant for double parton…
