Advanced Science, EarlyView.Artificial grain boundaries are created in BaTiO3$\text{BaTiO}_3$ thin films by freestanding membrane transfer, enabling direct isolation of a single boundary. Local ferroelectric switching and leakage are found to concentrate at the grain boundary, while increasing misorientation systematically enhances conduction.

Entropy‐Driven Physical Amplification in Multivalent Biosensing
Advanced Science, EarlyView.Detecting scarce molecules usually demands enzymatic amplification such as PCR. A statistical‐mechanical theory now reveals a purely physical alternative: distributing a fixed binding strength over more linker arms exponentially lowers the concentration at which multivalent sensors switch on.
