The traditional bulk-boundary correspondence assuring robust gapless modes at the edges and surfaces of insulating nodal topological materials gets masked in non-Hermitian (NH) systems by skin effect, manifesting an accumulation a macroscopic number states near such interfaces. Here we show that dislocation lattice defects are immune to effect or most display weak (depending on its relative ori...

Calorimetry measurements have been used to probe the melting of aluminum cluster cations with 63 to 83 atoms. Heat capacities were determined as a function of temperature (from 150 to 1050 K) for size-selected cluster ions using an approach based on multicollision-induced dissociation. The experimental method is described in detail and the assumptions are critically evaluated. Most of the alumi...

The melting point of palladium was determined by measuring with an optical P3^rometer the ratio of brightness of the red light (X= 0.6528m) emitted by black bodies at the melting points of palladium and gold, respectively. The crucible method was shown to be more reliable than the wire method. Especial attention was given to the purity of the metals. The result obtained by the crucible method, ...
