Humanized laboratory instruments - thanks to Colani

Colani lives on in the lab LUM GmbH is a leading international provider of innovative measurement technology for particle characterization in the nano and micro sector, for dispersion analysis and materials testing. Since 2015, there has been a close collaboration with star designer Luigi Colani on the ergonomic design of three new LUM measuring instruments. Luigi Colani (born August 2, 1928 in Berlin, † September 16, 2019 in Karlsruhe) was a German designer. Colani was known for his aerodynamic, biomorphic forms for cars, airplanes and many other commodities. He described his organic design language as a biodesign and defined this as a "humanization of the human-machine interface" through the "ergonomics and knowledge of the latest materials". The universal claim of his 3D philosophy led to a corresponding optimization of almost all customizable objects. Colleagues and journalists often regarded Colani's designs far ahead of the present [Wikipedia 29.10.2019, 09:44]. Far ahead, or at least

A cooperation project of TU Dresden, LUM and Doshisha University in Kyoto, Japan (Prof. Yasushige Mori) aimed at developing a transformation method from extinction weighted to volume or number weighted size distributions, which does not refer to a model that describes the optical behaviour of particles (e.g. Mie theory). As Dr. Frank Babick, TU Dresden, pointed out, this transformation can successfully be made by applying multi-wavelength analysis of photo-centrifugation data. Promising results were obtained with mineral materials SiO2, Al2O3, TiO2 as well as with Au. However, there seem to be materials, with which this transformation method without knowing the refractive index is not applicable.. Julia

Understanding the stability, behaviour and surface

properties of nanoparticles and quantum dots using Hansen Solubility Parameters Devices based on quantum dots & smart nanoparticles are currently getting a lot of attention. The colours, contrast & brightness of displays based on quantum dots provide benefits for users of TVs and phones. Unfortunately it’s not always obvious how the particles are going to interact with the other materials such as polymers, dispersants or solvents which form part of the product formulation. Dietmar Lerche of LUM GmbH is a speaker at the HSP50 conference in April 2017. “In order to tackle the challenges of compatibility and stability of particles, we took a look at the approach developed by Charles Hansen fifty years ago. Put simply, Hansen’s approach turns the chemist’s well-known rule of thumb, “like dissolves like” into a quantitative and predictive system that allows solvents and solutes to be matched to each other. We had seen that nanoparticles (or in effect their surfaces) could also be assigned their own set of Hansen Solubility Parameters (HSP).
