We present parallel single molecule detection (SMD) and fluorescence correlation spectroscopy (FCS) experiments with a fully integrated complementary metal oxide semiconductor (CMOS) single-photon 2 X 2 detector array. Multifocal excitation is achieved wit ...
The translational diffusion coeff. of an integral membrane protein/surfactant complex has been measured using a novel pulsed field gradient NMR method. In this new approach, the information about the localization of the mols. is temporarily stored in the f ...
A transport equation is derived which describes the behavior of the nanostructured metal oxide films in a photoelectrochem. cell. A detailed anal. of the charge compensation mechanism necessarily leads to a transport equation with characteristics similar t ...
Although a rigorous definition of growth-limiting substrate relies on a kinetic anal., a simple stoichiometric anal. based on the calcn. of the conversion is more applicable. Anal. of single and dual limitations is based on a simulated example for a substr ...
Telomerase uses an internal RNA moiety as template for the synthesis of telomere repeats. In Saccharomyces cerevisiae, the telomerase holoenzyme contains the telomerase reverse transcriptase subunit Est2p, the telomerase RNA moiety TLC1, the telomerase ass ...
The hydrodynamics were examd. of a multichannel (340 channels) tubular microreactor by exptl. detn. of the residence time distribution (RTD) using Ar or He in N2 and by theor. modeling. The dispersion was caused primarily by the laminar velocity profile an ...
Three perovskite-type compounds of composition La0.4Ca0.6Fe1-xCoxO3-d (x=o, o.25 and 0.5) were investigated for use as oxygen separation membranes for the partial oxidation (POX) of methane to syngas. Special attention was given to the question of their st ...
Molecular water channels (aquaporins) allow living cells to adapt to osmotic variations by rapid and specific diffusion of water molecules. Aquaporins are present in animals, plants, algae, fungi and bacteria. Here we present an electron microscopic analys ...
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
The diffusion-weighted signal attenuation of water in rat brain was measured with pulsed-field gradient nuclear magnetic resonance methods in a single voxel under in vivo and global ischemic conditions. The diffusion- attenuated water signal was observed i ...
