Behind the Paper
The real stories behind the latest research papers, from conception to publication, the highs and the lows
Mobile excitons discovered in quasi-one-dimensional metal TaSe3
Mobile excitons in metals have been elusive, as screening usually suppresses their formation. Here, the authors demonstrate such mobile bound states in quasi-one-dimensional metallic TaSe₃, taking advantage of its low dimensionality and carrier density.
Bioconjugates of photon-upconversion nanoparticles for cancer biomarker detection and imaging
Photon-upconversion nanoparticles that convert two or more low-energy photons to one photon of UV, visible or NIR light enable the detection and imaging of cancer markers without optical background interference.
