Significance We extend the concept of twistronics to elastodynamic metasurfaces with broken symmetries, unlocking exquisite control over phonon fields. Notably, we predict and experimentally ...

Emotions coordinate our behavior and physiological states during survival-salient events and pleasurable interactions. Even though we are often consciously aware of our current emotional state, such ...

(A) Schematic of a photocell consisting of quantum dots sandwiched between p and n doped semiconductors. Open circuit voltage and solar photon energy ℏνh are related by the Carnot efficiency factor ...

Measurement of the intrinsic contact angle of a flat surface. (A and B) Top (A) and side (B) views of a water nanodroplet on a flat solid hydrophobic surface. (C) Black points denote half-bulk-density ...
