(Phys.org)—IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM). The results ...

When asked to think of a chemical reaction, you might picture bubbling liquids in a beaker, or maybe applying heat to a mixture until something transforms. But some of the most important reactions in ...

In a recent letter (C&EN, May 21, page 2), David K. Lewis and John E. Baldwin suggest an alternative explanation for the experimental observations reported in our article "Biasing Reaction Pathways ...

Biological systems, ranging from single molecules to cells and tissues, have heterogeneous structural, biophysical and chemical properties that change dynamically to fulfill versatile functions. At ...

A microscopy technique originally developed to image the molecular-scale topography of surfaces is now helping engineers choose the right materials for a new generation of lightweight high-strength ...
