Title Piezoelectric properties of aligned collagen membranes
Electromechanical coupling, a phenomenon present in collagenous materials, may influence cellextracellular matrix interactions. Here, electromechanical coupling has been investigated via piezoresponse force microscopy in transparent and opaque collagen membranes consisting of helical-like arrays of aligned type I collagen fibrils self-assembled from acidic collagen solution. Using atomic force ...

متن کاملMetal Import through Microbial Membranes
Transport systems of Gram-negative bacteria coordinate the passage of metabolites through the outer membrane, periplasm, and the cytoplasmic membrane without compromising the protective properties of the cell envelope. Active transporters orchestrate the import of metals against concentration gradients. These thermodynamically unfavorable processes are coupled to both an electrochemical proton ...
متن کاملSimultaneous liquid viscosity and density determination with piezoelectric unimorph cantilevers
We have examined both experimentally and theoretically a piezoelectric unimorph cantilever as a liquid viscosity-and-density sensor. The fabricated piezoelectric unimorph consisted of a PbO•ZrO2•TiO2 ~PZT! layer on a thin stainless-steel plate. In addition to a driving electrode, a sensing electrode was placed on top of the PZT layer, permitting the direct measurement of the resonance frequency...
