2. Activated Carbon Pores Filled and Unfilled Using GAED and GC/MS Identification of Adsorbates

3. Full GAED Characterization with Vapor-phase Comparison of Extruded Wood Carbon

4. Full GAED Characterization with Aqueous-phase Comparisons of Fresh 1 (DD-314), Spent 1 (DD-315), Fresh 2 (DD-316), Spent 2 (DD-317)

5. GAED Determination of AC in Fly Ash from Coal Fired Electric Power Plants

6. GAED Comparison Of Two AC Carbon Cloth Materials
