source:phys.orgCarbon dots (CDs) are an intriguing class of nanomaterials that have attracted a great deal of attention in recent years. These carbon-based materials possess excellent fluorescence properties, making them highly appealing for a wide range of applications.Researchers at the Suzhou Institute of Biomedical Engineering and Technology (SIBET) of the Chinese Academy of Sciences recently developed novel aggregation-induced emission (AIE) carbon dots (Y-CDs) for cellular imaging.Results of this study were published in Materials & Design, titled "Rare earth-modified yellow carb...

source:phys.orgAn Oregon State University researcher who made color history in 2009 with a vivid blue pigment has developed durable, reddish magentas inspired by lunar mineralogy and ancient Egyptian chemistry.Mas Subramanian, distinguished professor of chemistry, and collaborators at OSU report the findings of the study in the journal Chemistry of Materials.The new pigments, which could be used as energy-efficient coatings for vehicles and buildings, are based on divalent chromium, Cr2+, and are the first to use it as a chromophore; chromophores are the parts of a molecule that determine colo...

source:Phys.orgResearchers at Harvard University, the Lawrence Berkeley National Laboratory, Arizona State University, and other institutes in the United States have recently observed an antiferromagnetic metal phase in electron-doped NdNiO3 a material known to be a non-collinear antiferromagnet (i.e., exhibiting an onset of antiferromagnetic ordering that is concomitant with a transition into an insulating state)."Previous works on the rare-earth nickelates (RNiO3) have found them to host a rather exotic phase of magnetism known as a 'noncollinear antiferromagnet,'" Qi Song,...
