Raman marker as a novel labeling reagent for the selective detection of biomolecules. Their use provides three key benefits: simultaneous detection of many different target molecules, high sensitivity and quantification of the detected biomolecules
A newly developed kite system allows to alter the line length while kite surfing by around 80% of the line length. This enables new kitesurf scenarios. Due to limited shore space kitesurfer may start with short lines and bring them full length later on the water. Furthermore, while surfing, the line length can be adjusted to wind conditions. After landing, the lines can be drawn in directly avoiding winding in and tangling of leashes.
Scientists from Goethe University of Frankfurt/Main synthesized novel arylborane compounds with extraordinary electronic, chemical, and optical properties. The novel blue fluorescent dyes are well suited for use in organic light emitting diodes (OLEDs).
The novel class of fluorophores with high quantum efficiencies is built around a pyrazole unit. These compounds exhibit emission maxima at around 380 nm. Additionally to high quantum efficiency and chemical resistance, the molecules provide a polar anchoring group enabling straightforward substrate attachment.
The invention provides the switching of magnetic properties in isolated (magnetically non–interacting) molecules in solution. Switching from the diamagnetic to the paramagnetic state is performed by irradiation with blue‐green light (500 nm), and the conversion back to the diamagnetic form is induced with blue‐violet light (435 nm). The process is fully reversible. No fatigue or degradation is observed after several thousand cycles at room temperature under air. In spite of the extremely high photosensitivity, the thermal conversion of the high energy paramagnetic state to the diamagnetic ground state is very slow (t1/2 at 54°C: 27 hours).
The invention can be used as optical storage media, switchable contrast agent for magnetic resonance imaging (dynamic MRI) and for contact free manipulation of objects.
A new family of layered titanates containing chemically bound unsaturated amine enables the fixation and immobilization of radioactive iodine-129 and iodine-131 from gaseous products of nuclear fission.
