This quote from the world renowned specialist in the field of in situ methods, Gabor A. Somorjai, clearly emphasizes the importance of these techniques in understanding heterogeneous catalysis - a type of chemical reaction used nowadays for most chemically produced supplies and fuels. Yet the fundamental mechanisms are often still not completely understood. Many of the leading scientists in the field have contributed to this book which provides an overview of the most varied spectroscopic and related methods for studying catalytic structures and their functions during a chemical reaction. While primarily written for users of these methods, this is also a valuable aid to interpreting the phenomena observed. Indispensable for everyone working in the field.Heterogeneous catalysisSpectrum analysisPhysical & Theoretical ChemistryHILCCChemistryHILCCPhysical Sciences & MathematicsHILCCHeterogeneous catalysisSpectrum analysisPhysical & Theoretical ChemistryChemistryPhysical Sciences & Mathematics541.3/95Haw James FPQKBBOOK9910146247703321In-situ spectroscopy in heterogeneous catalysis1934477UNINA04974nam 2200637Ia 450 991100667460332120200520144314.01-281-04763-597866110476340-08-053081-8(CKB)1000000000383899(EBL)313999(OCoLC)246692362(SSID)ssj0000071810(PQKBManifestationID)11969506(PQKBTitleCode)TC0000071810(PQKBWorkID)10091394(PQKB)10619711(MiAaPQ)EBC313999(EXLCZ)99100000000038389919960814d1996 uy 0engur|n|---|||||txtccrEmbankments on organic soils /edited by J.

Other Methods; 11.1 Reinforcement; 11.2 Pile foundation; 11.3 References; Author Index; Subject indexMore and more civil engineering constructions are being built on soft soils. As areas with better foundations are used up the necessity to be able to build structures on soft soils increases. The most troublesome of soft soils are organic soils due mainly to their high compressibility (much higher than in mineral soils), and also their very low shear strength. The large diversity of organic soils with respect to their origin as well as their properties make classification, testing, and engineering prediction of behaviour, very difficult. For this reason, engineers try, in general, to avoid cDevelopments in geotechnical engineering ;80.EmbankmentsHistosolsSoil mechanicsEmbankments.Histosols.Soil mechanics.624.1/62Hartlén Jan1824189Wolski Wojciech1824190MiAaPQMiAaPQMiAaPQBOOK9911006674603321Embankments on organic soils4391270UNINA
