The Micromechanical Measurement of Photothermal Expansion †

The measurement of photothermal expansion via the deflection of a cantilevered probe has attracted attention as a tool for the investigation of condensed-phase materials. In the present work, I provide a simple theoretical analysis of signal generation by this micromechanical det...

Proton flows, proton gradients and subcellular architecture in biological energy conversion

Hydrogen cations, or protons, provide a medium by which energy is stored in biological systems and converted for use in metabolic transformations. Such pre-eminence relies on the interplay between interfacial and bulk or chemical transformations, according to mechanisms that are...
