• World’s first LED lights developed from rice husks
  

  Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their new m more

• Nano ‘camera’ made using molecular glue allows real-time monitoring of chemical reactions
  

  Researchers have made a tiny camera, held together with ‘molecular glue’ that allows them to observe chemical reactions in real time. The device, made by a team from the University of Cambridge, combines tiny semiconductor nanocrystals called quantum dots and gold nanoparticles using molecular glue more

• 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

• 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
