High-Efficiency Photocatalytic H2O2 Production
Background Hydrogen peroxide (H2O2) is widely used for industrial synthesis of organic chemicals, advanced oxidation of drinking or wastewater, and surface disinfection of pathogens. Currently, ~95% of H2O2 production employs the energy- and chemical-intensive anthraquinone-oxidation process. Photocatalytic H2O2 production is an emerging alternative...

Coupling Photobiocatalysis to Biodegradation in a Circulating-Bed Biofilm Reactor
The proper treatment of wastewater is becoming more and more important as the number of toxic and biologically recalcitrant organic compounds continues to increase. Current treatment systems are sequentially coupled, in that they involve a two-step process of advanced oxidation followed by biodegradation. In the ideal case of sequential coupling, advanced...

Microbial Electro-Photosynthesis for improving energy conversion efficiency in photosynthetic microorganisms
While photosynthetic microorganisms offer a promising route to generate sustainable transportation fuels and products using solar energy, boosting their photosynthetic efficiency above normal levels (<5%) will help ensure its economic viability. A major source of inefficiency is that photosynthetically active radiation (PAR, 400-700 nm) constitutes...

Membrane Carbonation Technology for Efficient CO2 Delivery
In light of environmental concerns and the finite nature of petroleum-based sources, the production of biofuels and other valuable products from microalgae is very promising. Delivering concentrated CO2 is an essential step that enables microalgae cultivation to have high productivity and favorable economics. In order to achieve both benefits, the...

Atmospheric CO2 Enrichment and Delivery (ACED)
Microalgae are very useful biological systems for capturing carbon dioxide (CO2 ) and generating biomass and many useful products. Increasing the CO2 concentration in gas supplied to a microalgae growth system can improve its productivity many fold over using atmospheric air. Flue gas could be a good source of CO2 -enriched gas; however, its usefulness...

Membrane Biofilm Reactors (MBfRs) for High Volumetric Production Rate of Valuable Products
High petroleum costs coupled with major environmental concerns have pushed researchers to search for alternative and renewable sources of energy. Biomass represents an abundant, sustainable resource for energy production. Bio- and thermo-chemical conversion schemes often result in formation of energy-dense gases from biomass. Since as much as 30% of...

Reducing Obesity in Overweight Humans by Altering their Acetate and Energy Uptake through the Management of their Intestinal Microbial Communities
Obesity is epidemic in the United States, and it is increasingly a problem in much of the developed world. The health care costs associated with obesity and obesity-related diseases are a significant and increasing fraction of total healthcare spending. Currently, the most effective means to reverse obesity is surgical intervention: gastric bypass...
