Formaldehyde is a reactive and flammable aldehyde which is well known as one of the harmful volatile organic compounds. A_x000D_ combination of respiratory disease, allergic dermatitis and other ailments so called Sick Building Syndrome (SBS) is associated with chronic exposure to formaldehyde. Therefore, monitoring for formaldehyde is important in residential buildings. In this Phase I_x000D_ dev ...

Methane is the second most prevalent greenhouse gas emitted after carbon dioxide, however, on a pound-to-pound comparison methane has a 25 times greater impact on climate change than carbon dioxide over a 100-year period. Accordingly, the 2014 Climate Action Plan signed by President Obama has directed agencies including the USDA, DOE, and EPA to reduce methane emissions. A significant effort in th ...

Capacitive deionization (CDI) is a robust, energy efficient, and cost effective technology for water desalination. In collaboration with Dr. Satish Kumar and Dr. Costas Tsouris at Georgia Tech, we are developing nanostructured carbon material for effective and economical water and wastewater desalination. Our new approach for CDI is enabled by (1) synthesis of nanostructured high surface area acti ...

COAL TAR IS A BY-PRODUCT OF THE COAL GASIFICATION PROCESS USED WIDELY BETWEEN 1820 AND 1950 TO PRODUCE A NATURAL GAS SUBSTITUTE. DURING THAT TIME, BILLIONS OF GALLONS OF TAR WERE PRODUCED AT MORE THAN 1500 GAS MANUFACTURING FACILITIESLOCATED THROUGHOUT THE U.S. A LARGE PORTION OF THIS WASTE TAR REMAINS IN STORAGE OR WAS DISPOSED OF BY INJECTION INTO SUBSURFACE SITES. COAL TAR IS A MIXTURE OF HYDRO ...

RECENT ASSESSMENTS ESTIMATE U.S. CROP LOSSES FROM ELEVATED OZONE LEVEL AND OTHER OXIDANTS (SULFUR DIOXIDE, NITROGEN DIOXIDE) TO BE AS MUCH AS $5 BILLION ANNUALLY. ADDITIONALLY,SEVERE FOREST DAMAGE MAY RESULT FROMPOLLUTION-RELATED OXI- DANTS PARTICULARLY IN EUROPE WHERE THERE HAS BEEN A DRAMATICDECLINE IN FOREST ECOSYSTEMS OVER THE PAST SIX YEARS. THIS RESEARCH IS DIRECTED AT THE MITIGATION OF SUCH ...

NEW METHODS ARE NEEDED THAT RAPIDLY, ECONOMICALLY, AND EFFICIENTLY TREAT WASTEWATERS FOR REUSE OR DISPOSAL. ESTABLISHED WASTEWATER TREATMENT TECHNOLOGIES ARE EXPENSIVE AND CAN BARELY BE STRETCHED TO MEET THE REQUIREMENTS FOR WATER REUSE IN A PLANT OR DISCHARGE UNDER ENVIRONMENTALLY ACCEPTABLE CONDITIONS. OXIDIZING ORGANIC POLLUTANTS IN SITU ON ELECTROCATALYSTS DRIVEN BY ALTERNATING CURRENT. A MIXE ...

THE ECONOMIC USEFULNESS AND THE RANGE OF INFOMATION THAT CANBE OBTAINED FORM ON-LINE INFRARED GAS ANALYSIS IS LIMITED SINCE A COMPLEX AND UNRELIABLE EXTRACTIVE SAMPLING SYSTEM ORA DEDICATED SPECTROMETER IS NEEDED AT EACH SENSING POINT IN THE PROCESS. THIS PROGRAM INTENDS TO DEMOSTRATE THE FEASIBILITY OF TRANSMITTING THE IR SPECTRAL INFORMATION VIA OPTICAL FIBERS DRAWN FROM NEW MATERIALS--HEAVY MET ...
