Conformational study of melamine crosslinkers and spectroscopical comparison of HMMM molecules by practical measurements and quantum chemical calculations

Autor: Jochen S. Gutmann, Janek Wysoglad, Jan-Eric Ehlers, Michael Dornbusch, Tobias Lewe

Publikováno v: Journal of Molecular Structure. 1166:456-469

To understand and improve network formation processes and performance properties makes structural molecular studies critically important for the coil-coating industry. Crosslinking agents such as hexamethoxymethylmelamine (HMMM) or less methylated de

Mobility of Green Fluorescent Protein in Hydrogel-Based Drug-Delivery Systems Studied by Anisotropy and Fluorescence Recovery After Photobleaching

Autor: Jan-Eric Ehlers, Henning Menzel, Heike Bunjes, Andreas Bertz, Stefanie Wöhl-Bruhn, Karl-Heinz Gericke

Publikováno v: Macromolecular Bioscience. 13:215-226

Modified hydroxyethyl starch is photo-crosslinked in the presence of a green fluorescent protein (GFP) (mTagGFP) to obtain loaded hydrogels as model for a drug-delivery system. An important factor for the protein release is the crosslinking density s

Two-Color Two-Photon Excitation Using Femtosecond Laser Pulses

Autor: Jan-Eric Ehlers, Raluca Niesner, Stefan Quentmeier, Karl-Heinz Gericke, Stefan Denicke

Publikováno v: The Journal of Physical Chemistry B. 112:5768-5773

The use of two-color two-photon (2c2p) excitation easily extends the wavelength range of Ti:sapphire lasers to the UV, widening the scope of its applications especially in biological sciences. We report observation of 2c2p excitation fluorescence of

Steady-state and time-resolved two-photon fluorescence microscopy: a versatile tool for probing cellular environment and function

Autor: Stefan Denicke, Jan-Eric Ehlers, Raluca Niesner, Stefan Quentmeier, Karl-Heinz Gericke

Publikováno v: Physica Scripta. 76:C115-C121

In the last decade, the two-photon fluorescence laser-scanning microscopy (TPLSM) has become an indispensable tool for the bioscientific and biomedical research. TPLSM techniques as well as their applications are currently experiencing a dramatic evo

Theoretical Study on Mechanisms of the Epoxy−Amine Curing Reaction

Autor: Ha Pham, Jan-Eric Ehlers, Lam K. Huynh, Nelson G. Rondan, Maurice J. Marks, Thanh N. Truong

Publikováno v: Macromolecules. 40:4370-4377

Fundamental understanding of mechanisms of the epoxy−amine curing reaction is crucial for developing new polymer materials. Nearly all experimental studies, to date for elucidating its mechanisms are based on thermometric measurements and thus cann

Applications of the time-resolved two-colour two-photon excitation of UV fluorophores using femtosecond laser pulses

Autor: Jan-Eric Ehlers, K. H. Gericke, Stefan Denicke, Stefan Quentmeier

Publikováno v: Physica Scripta. 80:048105

A short overview of the principles and applications of the two-colour two-photon (2C2P) excitation of fluorescence by using femtosecond pulses is given. Fluorescence is generated by the simultaneous absorption of an 800 nm photon and a 400 nm photon
