This process, referred to as diffusion, is among the most general and basic phenomena in nature and determines the performance of many technological processes. This book provides an introduction to the fascinating world of diffusion in microporous solids. Jointly written by three well-known researchers in this field, it presents a coherent treatise, rather than a compilation of separate review articles, covering the theoretical fundamentals, molecular modeling, experimental observation and techni 606 $aPorous materials$xDiffusion rate 606 $aMaterials science 608 $aElectronic books. 615 0$aPorous materials$xDiffusion rate. 615 0$aMaterials science. 676 $a541.34 676 $a620.1/16 676 $a620.116 700 $aKa?rger$b Jo?rg$0920460 701 $aRuthven$b Douglas M$g(Douglas Morris),$f1938-$015735 701 $aTheodorou$b Doros Nicolas$0920461 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910141285603321 996 $aDiffusion in nanoporous materials$92064476 997 $aUNINA
