For Ph.D. students and others interested in chemical and biological charge transfer, and with an urge to approach charge transfer concepts and formalism beyond the trivial.
Contents: established and frontier elements of electron and atom group transfer in chemistry, biochemistry and biophysics. See course description.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
Have indsigt i kemiske redoxprocesser, elektrokemiske processer og biologiske elektrontransportprocesser.
Forstå disse bredt optrædende processer som fundamentale kvantemekaniske elektrontransportfænomener.
Være bekendt med basale elementer af kvantemekanisk og statistisk mekanisk teori, herunder den kvantemekaniske tunneleffekt.
Forstå og beskrive det omgivende reaktionsmediums betydning i kemisk og biologiske processer.
Have indsigt i de vigtigste elementer af kemisk og biologisk elektrontransportteori.
Kunne foretage beregninger af kemiske, elektrokemiske og biologiske hastighedskonstanter og vurdere de indgående procestypers egenskaber i relation hertil på basis af molekylær elektrontransportteori
Være bekendt med formalisme og begreber inden for andre molekylære elektriske ladningstransportfænomener som protontunneleffekt, kinetiske isotopeffekter, optisk induceret elektronoverførsel, elektronhop over store afstande m.m.
Forstå, beskrive og anvende elektrontransportbegreber i scanning tunnel mikroskopi og andre nye nanoteknologiske elektrontransportsystemer.
Kursusindhold:
Established and frontier elements of electron and atom group transfer in chemistry, biochemistry and biophysics. Topics to be chosen from:
1.The quantum mechanical tunnel effect in physical, chemical, and biological systems. 2.The liquid state of the environmental reaction medium. 3.The simplest chemical process - electron transfer: outer sphere electron transfer in inorganic and organic chemistry; dissociative electron transfer. 4.Towards preciser electron transfer theory: nuclear tunnelling; chemical processes at low temperatures; the diabatic and adiabatic limits. 5.Optical electronic processes and charge transfer spectroscopy. 6.Proton and atom group transfer: general acid and base catalysis, kinetic isotope effects. 7.The electrochemical process: the solid-liquid interface; electron transfer at metal and semiconductor electrodes; electron densities and electron tunnelling. 8.The notion of "long-range" electron transfer; intermediate states and intermediate matter; environmental dynamics and electron tunnelling. 9.Electron transfer in proteins and nucleic acids: molecular recognition; coherent processes; the photosynthetic apparatus; enzyme function and conformational dynamics. 10.Solvation and resolvation dynamics - the stochastic approach. 11.Perspectives and outlook: chemical nanostructures; molecular electronics; scanning probe microscopy, STM and AFM; ultrafast processes; charge transfer and phase transitions.
