• A new theory for Semiconductors made of nanocrystals
  

  Researchers at ETH have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or LEDs for TV screens. A few years ago, we were introduced to TV screens featur more

• 'Artificial chemist' combines AI, robotics to conduct autonomous R&D
  

  Researchers from North Carolina State University and the University at Buffalo have developed a technology called "Artificial Chemist," which incorporates artificial intelligence (AI) and an automated system for performing chemical reactions to accelerate R&D and manufacturing of commercially desira more

• Platelets instead of spheres make screens more economical
  

  ETH scientists have further developed QLED technology for screens. They have produced light sources that for the first time emit high-​intensity light in only one direction. This reduces scattering losses, which makes the technology extremely energy efficient. QLED screens have been on the market fo more

• Cytotoxicity studies of selected cadmium-based quantum dots on 2D vs. 3D cell cultures

  In our work, the cytotoxicity of selected, cadmium-based quantum dots with various surface architectures was studied on 3D spheroids. A specially designed microsystem as a tool for three-dimensional cell culture and nanoparticle toxicity evaluation was used for this aim. Two types of hydrophilic qua more

• Impacts of the Mn-ion in the ZnSe Passivation on Electronic Band Structure for High Efficiency CdS/CdSe Quantum Dots Solar Cells

  The surface passivation in quantum dot sensitized solar cells (QDSSCs) plays a very important role in preventing surface charge recombination and thus enhancing the power conversion efficiency (PCE). ZnSe passivation with dopant in CdS/CdSe co-sensitized QDSSCs has been demonstrated an effective way more

• Sustainable synthesis of single crystalline sulphur-doped graphene quantum dots for bioimaging and beyond

  The forbearing race of biomedical applications has given peak momentum to iconic trendsetter graphene quantum dots (GQDs). GQDs are zero-dimensional fluorescent carbon-nanomaterials, entailing pronounced quantum confinement effect, abundant edge states, and functional groups. Despite its potential a more
