Small Polaron-Induced Ultrafast Ferroelectric Restoration in Open
In this report, we apply a suite of ultrafast spectroscopic techniques and advanced calculations to reveal the interplay between electronic and lattice degrees of freedom in ferroelectric BiFeO3. Using transient sum frequency generation sp…

Spatially dependent H-bond dynamics at interfaces of water/biomimetic self-assembled lattice materials Open
Significance It is challenging to develop biomimetic lattice self-assemblies because such materials need to resemble the flexibility and crystallinity of their biological analog. We show that these materials exhibit unique micro- and mesos…
