20th Winter Workshop on Molecular Acoustics, Relaxation and Calorimetric Methods, now combined to an international, fully integrated event, encompasses the most broadly considered topics of Materials of the Future. While conforming to the most stringent criteria of scientific excellence and enjoyable(!), fruitful collaboration, we invite you to discuss all aspects of organic, inorganic, and pure-carbon (including flexible and wearable) #electronics: OFETs, OLEDs, solar cells, supercapacitors, electrolytes, and #thermodynamics: heat transfer (io)nanofluids, multifunctional greases, phase change materials, etc. Let us electrify, illuminate, and warm up the future now – all in a sustainable and responsible way.
