Control Strategies to Reduce Emissions

Emissions Control Options For POTWs

ublicly owned treatment works (POTWs) are beginning the process of identifying air emissions from their wastewater treatment and collection facilities. Many of these facilities will be required by local and state regulatory agencies to reduce emissions to meet air quality or health risks standards. Emissions include odors and toxic, reactive, volatile and criteria pollutants. A wide range of re...

Dynamic control of catalysis within biological cells

We develop a theory of enzyme catalysis within biological cells where the substrate concentration [S](t) is time dependent, in contrast to the Michaelis-Menten theory that assumes a steady state. We find that the time varying concentration can combine, in a non-linear way, with the ruggedness of the free energy landscape of enzymes (discovered both in single molecule studies and in simulations)...

Environmental control of nucleophilic catalysis in water.

The nucleophilic catalysis by a pyridyl group in ester/phosphate ester hydrolysis was modulated by the microenvironmental hydrophobicity around the catalyst. The catalytic efficiency was enhanced thousands or tens of thousands of times and the activity was maintained well below the pKa of the pyridyl group.
