Methods and conditions to test these materials introduce large discrepancies and overestimates (~90%) in the reported literature. This study describes a simple apparatus utilizing hand-held inexpensive gas sensors for testing adsorbents and hybrid adsorbent materials, explains possible sources for the observed discrepancies based on how the measurements are made, and provides guidelines for accurate measurements of adsorption capacity. Ammonia was the model gas and Ammonasorb™ activated carbon was the model commercial adsorbent. Inlet ammonia concentration, residence time, adsorbent pre-treatment (baking) and humidity, affected the measured adsorption capacities. Results suggest that the time lag in gas detection sensors leads to overestimated capacities. Monitoring both inlet and outlet concentrations using two calibrated sensors solved this issue. There was a direct relationship between adsorption capacity and residence time and capacities were higher at higher inlet concentrations. The size of the adsorbent particles did not show a significant effect on adsorption breakthrough, and the apparatus was able to quantify how humidity reduced the adsorption capacity.}, number={5}, journal={MEASUREMENT SCIENCE AND TECHNOLOGY}, author={Amid, Hooman and Maze, Benoit and Flickinger, Michael C. and Pourdeyhimi, Behnam}, year={2017}, month={May} } @misc{amid_maze_flickinger_pourdeyhimi_2016, title={Hybrid adsorbent nonwoven structures: a review of current technologies}, volume={51}, ISSN={["1573-4803"]}, DOI={10.1007/s10853-016-9741-x}, number={9}, journal={JOURNAL OF MATERIALS SCIENCE}, author={Amid, Hooman and Maze, Benoit and Flickinger, Michael C. and Pourdeyhimi, Behnam}, year={2016}, month={May}, pages={4173–4200} } @article{amid_jeddi_salehi_dabiryan_pejman_2016, title={INVESTIGATION OF CIRCULAR WOVEN COMPOSITE PREFORMS FOR COMPOSITE PIPES}, volume={16}, ISSN={["2300-0929"]}, DOI={10.1515/aut-2015-0036}, abstractNote={Abstract The main traditional technique for commercial manufacturing of composite pipes is filament winding in which the winding angle and the discontinuity of the structure (caused by starting and ending points of the winding process) are two important matters of concern. In the present study, circular woven fabric with its orthogonal net-shaped continuous structure was produced from polyester yarns. Fabric was wet with epoxy and hand lay-up was used to manufacture the composite pipes. Composite pipes were subjected to internal hydrostatic pressure and their burst strength was recorded. In addition, tensile strength of flat laminas was assessed in the warp and weft directions. We estimated and analysed the failure strength of composite pipes using Tresca’s failure criterion and Finite Element (FE) modeling. The experimental burst strength was almost 23% more than the FE model and 77% more than the theoretical estimate.}, number={2}, journal={AUTEX RESEARCH JOURNAL}, author={Amid, Hooman and Jeddi, Ali Asghar Asgharian and Salehi, Manouchehr and Dabiryan, Hadi and Pejman, Reza}, year={2016}, month={Jun}, pages={100–108} }
