• Breakthrough could enable cheaper infrared cameras
  

  There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up the secret light emitted as plants photosynthesize, as cool stars burn and batteries get hot. They can see through smoke and fog and plastic. But infrared came more

• New water splitting catalyst could make it easier to generate solar fuel
  

  Water splitting, the process of harvesting solar energy to generate energy-dense fuels, could be simplified thanks to new research including faculty at Binghamton University, State University of New York. "The key idea is to generate a solar fuel: hydrogen gas, which can be burnt to release energy o more

• A burst of ”synchronous” light
  

  Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This disco 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
