The role of the transcription factor BARHL1 in medulloblastoma [PDF]

, 2011
Das Medulloblastom ist der häufigste maligne Hirntumor des Kindesalters, und die Entwicklung von zielgerichteten, nebenwirkungsarmen Therapiestrategien hat oberste Priorität. Die molekularen Mechanismen der malignen Transformation dieses Tumors sind noch

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

Advanced Materials, EarlyView.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

Advanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.
