Application of Microfibrous Materials in Air Filtration for Improving Indoor Air Quality

Chen, Yanli (2012-07-27)

The growing emphasis on indoor air quality has resulted in the need for more stringent air filtration requirements in heating, ventilation, and air conditioning (HVAC) systems. The typical filtration system consists of a ...

Applications of Electrochemical Impedance Spectroscopy to in-situ Dynamic Characterization of Energy Conversion and Storage Systems

Zhu, Ying (2013-12-05)

Electrochemical impedance spectroscopy (EIS) is considered as a powerful and valid technique for non-destructive in-situ dynamic measurement of electrochemical power systems. Together with equivalent circuit (EC) simulation, ...

Development of Cathode Air Filters for PEM Fuel Cells Using Microfibrous Entrapped Sorbents

Phalle, Abhijeet (2013-11-25)

The performance of Proton Exchange Membrane Fuel Cell (PEMFC) is degraded significantly as a result of poisoning of the cathode catalyst by trace levels of contaminants present in the cathode air. Three of the most common ...

Enhanced Heat Transfer Catalyst Structures for Fischer-Tropsch Synthesis

Sheng, Min (2012-01-10)

Highly exothermic catalytic reactions are problematic from a thermal management perspective and often dictate the type of reactor, heat exchanger, level of conversion/recycle and contacting schemes employed. Those reactions, ...
