A sensor comprising a membrane containing bacteriorhodopsin. In one embodiment, the sensor comprises a layer of purple membrane between a first and a second electrode, wherein the electrodes are connected to a circuit such that a signal is produced when a charge is transferred across the membrane. In another embodiment, the sensor comprises a field effect transistor with a layer of purple membrane deposited on the gate. The layer of purple membrane may be further functionalized by adding fluorophores to the layer of purple membrane. The fluorophores may be deposited adjacent to the layer of purple membrane, or the fluorophores …

Distillation process consumes about 40% of the total energy used to operate the plants in petrochemical and chemical process industries in North America. Therefore, sustainable distillation column operation requires responsible use of energy and reduction of harmful emission such as CO2. The Aspen Plus ‘Column Targeting Tool’ (CTT) options in a simulation environment can help reduce the use of energy and hence CO2 emission. The Aspen plus ‘Carbon Tracking’ (CT) together with the ‘Global Warming Potential’ options can quantify the reduction in CO2 emission. The CTT is based on the practical near-minimum thermodynamic condition approximation and …
