After a brief introduction to Functional Magnetic Resonance Imaging (fMRI), this paper presents some common misunderstandings and problems that are frequently overlooked in the application of the technology. Then, in three progressively more involved examples, the paper demonstrates (a) how use of fMRI in pre-surgical mapping shows promise, (b) how its use in lie detection seems questionable, and (c) how employing it in defining personhood is useless and pointless. Finally, in making a case for emergentism, the paper concludes that fMRI cannot really tell us as much about ourselves as we had hoped. Since we are more than our brains, even if fMRI were perfect, it is not enough.

In an effort to provide drinking water treatment options that are simple to operate, two hybrid resins have been developed that can treat multiple pollutants in a single step. A parent weak base anion exchange resin is embedded with nanoparticles made of either iron hydroxide or titanium dioxide (Fe-WBAX and Ti-WBAX, respectively). These provide targeted treatment for both arsenic and hexavalent chromium, common groundwater pollutants of recent regulatory significance. The project goal is to evaluate the environmentally preferable choice between Fe-WBAX and Ti-WBAX resin for simultaneous treatment of arsenic and hexavalent chromium in drinking water. The secondary goal is to identify where in the product life cycle is the most opportunity to reduce the environmental impact of the use of either product.
