Materials Challenges

Although much as been done, much work remains. Improved material models for anisotropic materials, brittle materials, and chemically reacting materials challenge the numerical methods to provide greater accuracy and challenge the computer manufacturers to provide more memory and speed. Phenomena with different time and length scales need to be coupled so shock waves, structural motions, electromagnetic, and thermal effects can be analyzed in a consistent manner. Smarter codes must be developed to adapt the mesh and solution techniques to optimize the accuracy without human intervention.

There are a number of reasons for the absence of CBRN attacks including the technical and material challenges. In addition, while al Qaeda is set to destroy the West, few other groups have the motivation to kill large numbers of people. Other factors include terrorists prefer the certainty of conventional weapons to the uncertainty of CBRN the weapons can be hazardous to the terrorists themselves the response to a CBRN terrorist attack may result in further degradation of terrorist capabilities and finally political support of the terrorist organization s base may be turned away by the use of unconventional tactics.

We close by apologizing that you may find the following chapters described by some combinations of superficial, incomplete, random, and wrong. However, we need make no apolo for this in an introductory course if you find the material challenging and fun There are many complete texts and monographs on each of these subjects, and any student wanting to know more about them should locate these books or take relevant courses.

In chapter 4, Stonehart (a major authority in the field of H2 fuelcell technology and its fundamental aspects) writes, with co-author Wheeler, on the topic of Phosphoric Acid Fuel-Cells (PAFCs) for Utilities Electrocatalyst Crystallite Design, Carbon Support, and Matrix Materials Challenges. This contribution reviews, in detail, recent information on the behavior of very small Pt and other alloy electrocatalyst crystallites used as the electrode materials for phosphoric acid electrolyte fuel-cells.
