The 2/3 Rule of Glass Physics Implies Universalities in Crystal Melting
Peter Lunkenheimer, Konrad Samwer, Alois Loidl
Since more than 100 years, melting is thought to be governed by the Lindemann criterion. It assumes that a crystal melts when, upon heating, the growing atomic vibration amplitudes…
Broadband Dielectric and THz Spectroscopy on Bio-Related Matter: Water, Amino Acids, Proteins, and Blood
Peter Lunkenheimer, Sebastian Emmert, Martin Wolf +1
In the present work, we examine the relevance and proper interpretation of broadband-dielectric and THz-spectroscopy data for the investigation of various types of biological matte…
Relaxation dynamics of poly(ethylene oxide)
Peter Lunkenheimer, Alois Loidl
Poly(ethylene oxide) is an important polymer with many applications, e.g., as solid-state electrolyte in batteries. Its relaxation dynamics, characterizing its molecular and submol…
Crystal melting influenced by particle cooperativity of the liquid
P. Lunkenheimer, K. Samwer, A. Loidl
Recently, a universal relation between the thermal expansion coefficient of glasses , their glass-transition temperature Tg, and the so-called fragility index m of the corresp…
Prigogine-Defay ratio of glassy freezing scales with liquid fragility
Alois Loidl, Peter Lunkenheimer, Konrad Samwer
A detailed study of published experimental data for a variety of materials on the incremental variation of heat capacity, thermal expansion, and compressibility at glassy freezing…
Ionic conductivity of a lithium-doped deep eutectic solvent: Glass formation and rotation-translation coupling
A. Schulz, P. Lunkenheimer, A. Loidl
Deep eutectic solvents with admixed lithium salts are considered as electrolytes in electrochemical devices like batteries or supercapacitors. Compared to eutectic mixtures of hydr…
