Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...

Resonance in chemistry is a tool used (predominately in organic chemistry) to represent certain types of molecular structures. Resonance is a key component of valence bond theory and arises when no ...

Surface plasmon resonance (SPR) is a real-time, label-free optical technique used to detect and quantify molecular interactions. SPR has important applications in drug discovery and development and ...

Meet Steven Turner, curator at the Smithsonian's National Museum of American History, as he discusses the Smithsonian's scientific instrument collection. This video focuses on instruments that ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...

It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...
