Towards an improvement of model transferability for Raman spectroscopy in biological applications

One of the most important issues for the application of Ramanspectroscopy for biological diagnostics is how to deal efficiently with large datasets. The best solution is chemometrics, where statistical...

Secondary structure and glycosylation of mucus glycoproteins by raman spectroscopies

The major structural components of protective mucus hydrogels on mucosal surfaces are the secreted polymeric gel-forming mucins. The very high molecular weight and extensive O-glycosylation of gel-forming...

Excitation energy dependent ultrafast luminescence behavior of CdS nanostructures

Cadmium sulfide (CdS) nanostructures were excited under ambient conditions by femtosecond (fs) laser pulses (380 nm<lambda_ex < 440 nm, tau=50 fs, rep. rate = 1 kHz, fluence<6.7 mJ/cm2). Their...

Controlling Electronic Transitions in Fullerene van der Waals Aggregates via Supra-Molecular Assembly

Morphologies crucially determine the optoelectronic properties of organic semiconductors. Therefore, hierarchical and supra-molecular approaches have been developed for targeted design of supramolecular...

Scaling supercontinuum generation in gas-filled hollow-core fibers

We report on two novel approaches for improved scaling supercontinuum generation in gas-filled hollow-core fibers. Switching either from atomic to molecular gases or from capillaries to novel anti-resonant...

Watt-level femtosecond mid-infrared sources in the wavelength range from 4.1 µm to 8.5 µm

A huge variety of molecules exhibits vibrational resonances in the mid-infrared (mIR) and thus the wavelength region is extremely attractive for spectroscopic applications like human breath or trace gas...

Intentional formation of a protein corona on nanoparticles: Serum concentration affects protein corona mass, surface charge, and nanoparticle-cell interaction

The protein corona, which immediately is formed after contact of nanoparticles and biological systems, plays a crucial role for the biological fate of nanoparticles. In the here presented study we describe...

Diffusion and Viscous Flow Effects at Preparation of Microstructured Optical Sensor Fibers

Bifacial multicrystalline silicon thin film solar cells

Thanks to the fast development in recent years, over 12% efficiencies have been reached on multicrystalline silicon (mc-Si) thin film solar cells. These values are already close to those commercially available...
