• Luminescent wood could light up homes of the future
  

  The right indoor lighting can help set the mood, from a soft romantic glow to bright, stimulating colors. But some materials used for lighting, such as plastics, are not eco-friendly. Now, researchers reporting in ACS Nano have developed a bio-based, luminescent, water-resistant wood film that could more

• Photocatalysts show promise in creating self-cleaning surfaces and disinfecting agents
  

  A joint paper by Kazan Federal University, Boreskov Institute of Catalysis, and Russian Oil and Gas University was published in Chemistry - A European Journal. The team produced and studied new active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots stabili more

• Efficient valves for electron spins
  

  Researchers at the University of Basel in collaboration with colleagues from Pisa have developed a new concept that uses the electron spin to switch an electrical current. In addition to fundamental research, such spin valves are also the key elements in spintronics – a type of electronics that expl 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
