ZNS-Störungen bei Myotoner Dystrophie
Patienten mit Myotoner Dystrophie (MD) weisen Blickfolgestörungen auf. Da dieses auch für die Suppression des Vestibulo-okulären Reflexes VOR-S) gilt, schloss man, dass eine zentrale Ursache zugrunde liegt. Ein häufiger Befund in kraniellen Magnetresonanztomographien (MRT) bei der MD sind …

Exzitotoxizität im ZNS bei Mausmutanten mit veränderten Glutamatrezeptoren
Excitotoxicity is a detrimental condition that accompanies acute brain damage such as stroke. Extensive studies have documented that excitotoxicity is mediated by the NMDA receptors and the excessive Ca2+ influx triggered by prolonged NMDA channel activation. However, the contribution to …

Lokalisation von hochaffinen Glutamattransportern in verschiedenen ZNS-Regionen der Maus
… muss Glutamat aus dem Extrazellularraum des ZNS entfernt werden. Dafür sind die hochaffinen Glutamattransporter in Gliazellen und Neuronen zuständig, die Glutamat aus dem Extrazellularraum aufnehmen. In der vorliegenden Arbeit wurde die regionale und zelluläre Verteilung der …

Integration of CdSe/ZnS Quantum Dots into As-induced Etched Nanovoids on GaSb
… the infra-red. The colloidal synthesis of CdSe/ZnS quantum dots is presented, to describe their incorporation into nanovoids formed on GaSb membranes. Nanoscale etch-pit formation on GaSb surfaces happens as a result of arsenic (As2) based in situ etch technique. The effect of in situ etch …

HIGH TEMPERATURE ZnSe:Mn/ZnS NANOPHOSPHORS WITH VERY HIGH QUANTUM EFFICIENCY FOR WHITE LEDs
… A novel technique for colloidal synthesis of ZnSe:Mn/ZnS nanocrystals (NCs) is also presented here, using a growth doping technique that exhibits a bright emission peak at 587 nm with excellent thermal behavior and record high quantum efficiency. The 587 nm peak from the Mn dopant exhibits a …

Power Dependent Study of CDSE-ZNS Quantum Dot Relaxation Dynamics by 2D Muppets
<p>CdSe-ZnS core-shell quantum dot relaxation dynamics are multiexponential and have a strong power dependence. Because single exciton and biexciton populations, are indistinguishable by any-dimensional experiments, there is uncertainty as to whether this power dependence comes from a biexciton or …

Efficient light emitting devices utilizing CdSe(ZnS) quantum dots in organic host matrices
… thin film structures containing core-shell CdSe(ZnS) quantum dots dispersed in molecular organic host materials. In the most efficient devices, excitons are created on the quantum dot sites via energy transfer from organic host molecules, and direct charge injection into the quantum dots is …

Toward the Synthesis and Characterization of Pb-Doped ZnS Nanocrystals for Solar Energy Applications
… lattice strain in the host crystals. Lead-doped ZnS nanocrystals are one promising material for the conversion of solar photons into storable fuels such as hydrogen gas. The ZnS conduction band is sufficiently high in energy to reduce protons, and the lead dopants are hypothesized to add filled …
