Excited-state deactivation mechanism in Nickel-Tetra-Mesityl-Porphyrin.

Phosphine-Dissoziation in Gold-Clusters

CD45 exclusion– and cross-linking–based receptor signaling together broaden FceRI reactivity

For many years, the high-affinity receptor for immunoglobulin E (IgE) FceRI, which is expressed by mast cells and basophils, has been widely held to be the exemplar of cross-linking (that is, aggregation...

Remote control of electronic coupling – modification of excited-state electron-transfer rates in Ru(tpy)2-based donor-acceptor systems by remote ligand design

A comprehensive understanding of how the molecular structure influences the electronic coupling is crucial in optimizing (supra) molecular assemblies for photoinduced electron transfer. Here, we report...

Intercomparison of far-infrared transmittance measurements

We present the results of the first systematic “round-robin” comparison of farinfrared transmittance spectra measurements, which was performed by five laboratories and piloted by Physikalisch-Technische...

The Hollow Core Light Cage: Trapping Light Behind Bars

Optical waveguides represent the key element of integrated planar photonic circuitry having revolutionized many fields of photonics ranging from telecommunications, edicine, environmental science and...

Super-resolution microscopy demystified

Super-resolution microscopy (SRM) bypasses the diffraction limit, a physical barrier that restricts the optical resolution to roughly 250 nm and was previously thought to be impenetrable. SRM techniques...

Optical Fiber Probe Viscometer based on Hollow Capillary Tube

Viscosity measurements of a solution are crucial for many processes involving fluid flows. The current optical fiber viscometers are complex and, in some cases, provide indirect measurements of viscosity...

Molecular recognition of the native HIV-1 MPER revealed by STED microscopy of single virions

Antibodies against the Membrane-Proximal External Region (MPER) of the Env gp41 subunit neutralize HIV-1 with exceptional breadth and potency. Due to the lack of knowledge on the MPER native structure...

Raman-based cw supercontinuum generation in a fiber ring laser with low-output coupling

We demonstrate a new technique to generate a continuous-wave supercontinuum based on the stimulated Raman effect in an Yb-based ring laser configuration. Continuously pumping this ring cavity with a maximum...
