Behind the Paper
The real stories behind the latest research papers, from conception to publication, the highs and the lows
It is common sense that emission maxima of phosphorescence spectra (λP) are longer than those of fluorescence spectra (λF). We report a serendipitous finding of up-converted room-temperature phosphorescence with λP < λF and phosphorescence lifetime > 0.1 s in dopant-matrix systems.
Lab-scale UV-Vis Spectroscopy Monitors Oxidation State Changes in Materials for Energy Storage
We report the use of affordable and widely-available UV-Vis spectroscopy to monitor redox activities during charge storage. The data allowed us to distinguish charge storage mechanisms and quantify the oxidation state changes, similar to synchrotron-based X-ray absorption spectroscopy.
Metal oxide single-component light-powered micromotors for photocatalytic degradation of nitroaromatic pollutants
The extensive employment of nitroaromatic pollutants has led to severe contamination of the environmental waters. Here, we proposed low-cost single-component WO3 microrobots capable of efficient photodegradation of nitroaromatic pollutants in a sustainable way.
