Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov are awarded the Nobel Prize in Chemistry 2023 for the discovery and development of quantum dots. These tiny particles have unique properties and now spread their light from television screens and LED lamps. They catalyse chemical reactions and their clear light can illuminate tumour tissue for a surgeon.[1] LUM GmbH cordially congratulates this year's award winners. Since 1998, users in research and industry have been using the innovative analysis devices, made by LUM GmbH, for comprehensive particle and dispersion characterization, for determining joint and layer strengths and for recording product and process parameters. In the laboratory, at-line and, more recently, in-line. The analytical centrifuges from the LUMiSizer product line are also used in research on quantum dots and their applications.
Zhongliang Hu et al. reported the use of carbon quantum dots (CQDs) as nanoparticle tracers and sensors for reservoir exploration and development in oil and gas production. The stability of several CQD suspensions against high salinity was tested at 40 °C. [2]
Sebastian Süß et al. extended a previously developed standardized and non-subjective method for determination of Hansen parameters based on analytical centrifugation to the important class of quantum materials. As a technically relevant model system, zinc oxide quantum dots (QDs) were used. [2]
The multidimensional classification of quantum dots is the research topic of Menter and Segets; they used analytical centrifugation to determine the sedimentation-equivalent distribution of the flake diameters of ZnS quantum dots.[2] Jos van Rijssel et al. used the LUMiSizer in the context of determining the size-dependent second virial coefficient of the osmotic pressure of quantum dots, an important parameter for quantifying and comparing molecular and colloidal interactions.
