This volume is a new follow-up volume that complements Dynamic Light Scattering (1993) by the same author. The volume is directed to the recent development in the light scattering technique and to describing a wide spectrum of its applications. Both the theoretical development and utilization are traced by authors who are expert in their fields. Development in static light scattering as applied to simple liquids, polymer solutions, and multi-component polymer mixtures are dealt with. The scattering theory of colloidal dispersions is described and scattering from rod-like polyelectolytes is reviewed. There are chapters on concentrated polymer systems, aggregation phenomena, polymer-polymer interactions, polyelectrolytes in solution. Emphasis is given to more complex systems, for example, ternary polymer systems, complex micellar systems, and block copolymers in the ordered and disordered states. Low-angle light scattering is reviewed, as well as simultaneous static and dynamic light scattering. The determination of particle size distributions and combined chromatographic light scattering techniques are also treated.

First Published in 2006. This volume introduces and provides a semantic analysis of Discourse Adjectives, a natural class of adjectives that the author argues includes apparent, clear, evident, and obvious among its prototypical members. With a main claim that Discourse Adjectives do not provide information about the facts of the world. Rather, they are used by interlocutors to negotiate the status of propositions in a discourse.

From the late-1960's, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The "gold standard' amongst the many variations that exist today has been, and to a great extent still is, DuPont's Nafion (R) family of materials. However, there is significant concern in the industry that these materials will not meet the cost, performance, and durability requirementsnecessary to drive commercialization in key market segments - es- cially automotive. Indeed, Honda has already put fuel cell vehicles in the hands of real end users that have home-grown fuel cell stack technology incorporating hydrocarbon-based ionomers. "Polymer Membranes in Fuel Cells" takes an in-depth look at the new chem- tries and membrane technologies that have been developed over the years to address the concerns associated with the materials currently in use. Unlike the PFSAs, which were originally developed for the chlor-alkali industry, the more recent hydrocarbon and composite materials have been developed to meet the specific requirements of PEM Fuel Cells. Having said this, most of the work has been based on derivatives of known polymers, such as poly(ether-ether ketones), to ensure that the critical requirement of low cost is met. More aggressive operational requi- ments have also spurred the development on new materials; for example, the need for operation at higher temperature under low relative humidity has spawned the creation of a plethora of new polymers with potential application in PEM Fuel Cells.
