Presenting both synthesis and characterization protocols, this book charts the use of spectroscopy in characterizing structural and chemical heterogeneity. It shows how intra- and inter-particle resistance affect adsorbent transport; deals with the utilization of nanostructural materials in gaseous and liquid environments; emphasizes the importance of structural and energetic heterogeneity and its influence on the performance of three dimensional materials; presents case studies illustrating the adsorption properties of surfaces; and more.

From the Preface: “In the world of nanoparticles and microporous materials, the interaction forces between nanosized particles and molecules from the surrounding medium, or the forces between particles themselves, may exceed the mechanical forces between bodies of the macroscopic world. This is caused by the high surface-to-volume ratio of nanoparticles and microporous materials. When familiar materials become mainly surface, they acquire new optical, magnetic, electrical, chemical, and transport properties. Thus, dispersions tend to agglomerate, fine particles show increased mechanical strength, and microporous solids develop tremendous sorption and molecular sieving properties......”

Target Audience: Physical, surface, colloid, inorganic, organic, polymer, medicinal, and analytical chemists; chemical engineers; materials scientists; biochemists and biophysicists; and upper-level students in these disciplines.
