Because sour taste is the perception of acidic substances, which have a high concentration of protons, Liman
predicted that sour taste cells have an
ion channel that responds to or
transports protons.
Dr. Rosso's current projects include the following: (1) characterizing the kinetics and mechanisms of elementary charge and
ion transport processes in redox transformation of iron oxide minerals, (2)
predicting molecular - scale electron transfer kinetics in microbially - mediated reduction of bioavailable iron in subsurface environments, (3) studying mechanisms of heterogeneous reduction of contaminant U (VI) and Tc (VII) by Fe (II)- bearing minerals, (4) simulation of coupled charge and
ion transport in transition metal oxide electrodes for advanced materials applications, (5) probing mechanisms and kinetics of mineral transformation to metal carbonates for geological carbon sequestration, and (6) studying mechanisms of uptake and retention of uranium in sediments.
