Membranes for photocatalysis in water and wastewater treatment
2011
Abstract: The chapter reports the basic principles of heterogeneous photocatalysis together with a brief presentation of the types of membranes and membrane operations most widely used in this type of application. Coupling the two technologies with the aim of obtaining synergistic effects for conversion in liquid–solid systems is discussed and the relevant papers together with some case studies in pollutants abatement and reaction of synthesis are highlighted.
Discrete Time Versus Continuous Time Approach to the Autoimmune Response
1989
A discrete time model for the immune regulation recently proposed by Weisbuch and Atlan is extended to continuous coupling coefficients as well as to continuous concentration rates in continuous time. It is shown that depending on the choice of the network parameters typical immune responses can be observed.
Theta power and theta-gamma coupling during formation of novel representations in the infant brain
2021
Item does not contain fulltext Building object representations is crucial for understanding the visual world, but it is not yet understood how infants start to form these representations. In adults, theta power is higher during presentation of stimuli that were later remembered, compared to those later forgotten (Friese et al., 2013), and the coupling between theta phase and gamma amplitude has been shown to be responsible for binding perceptual features to form representations. Theta-gamma coupling has been observed, for example, during the formation of visual associations (Köster, Finger, Graetz, Kater & Gruber, 2018), and was again higher for remembered than forgotten stimuli. Theta-gamm…
Electronic Excitation Energy Transfer in Multichromophoric Assemblies: A Single Molecule Insight
2009
In recent years, single molecule spectroscopy has provided novel insights into the fundamentals of electronic excitation energy transfer in molecular aggregates. In order of increasing structural complexity, we have studied simple molecular dimers and multichromophoric dendrimers. It will be shown that the combination of frequency-selective single molecule spectroscopy and confocal fluorescence microscopy at 1.4 K is a unique tool to study energy transfer processes in these systems. In particular, from the line widths of single molecule excitation spectra, rate constants of energy transfer can be deduced directly. A detailed analysis shows that, for several cases, the mechanism of energy tr…
ChemInform Abstract: Powerful Fluoroalkoxy Molybdenum(V) Reagent for Selective Oxidative Arene Coupling Reaction.
2014
A novel dinuclear fluoroalkoxy Mo(V)-complex is efficient as reagent for the oxidative arene coupling of electron-rich arenes with superior reactivity compared to MoCl5 and MoCl5/TiCl4.
