As for most of the topics in the field of solidification, Mert Flemings has always pioneered new ideas. While much of the understanding of hot tearing formation was already known about 30 years ago, he devised with Metz an interesting apparatus for studyin ...
A review, with over 209 refs., is given on the prepn. and structures of all known salts of the known homopolyat. cations of the chalcogens and halogens. The structures of these cations, many of which are nonclassical and cluster-like, arise from pos. charg ...
The attempt to prep. hitherto unknown homopolyat. cations of sulfur by the reaction of elemental sulfur with blue S8(AsF6)2 in liq. SO2/SO2ClF, led to red (in transmitted light) crystals identified crystallog. as S8(AsF6)2. The X-ray structure of this salt ...
Two important effects were found in rapidly quenched Al-Si alloys: (i) the enhancement of the electron-phonon coupling parameter, revealed by the variation of Tc and the slope of thermal resistivity; (ii) the metastability of these crystalline metallic all ...

We study the phase transition in SU(2)-Higgs model on the lattice using the 3D dimensionally reduced formalism. The 3D formalism enables us to obtain highly accurate Monte Carlo results, which we extrapolate both to the infinite volume and to the continuum ...
A comprehensive micro-macroscopic model of the continuous hardening of 3d-axisymmetric steel components by induction heating has been developed. At the macroscopic scale, the Maxwell and heat flow equations are solved using a mixed numerical formulation : ...
The conditional sampling formulation typically used in eddy accumulation flux measurements was tested at two sites using velocity, temperature, and specific humidity time series measurements. The first site was at Owen's Lake in southern California, and th ...
The nitric oxide monomer-dimer equil. was monitored at 273-364 K. The enthalpy change for the reaction 2 NO -> (NO)2, calcd. from the temp. dependence of the UV absorption intensity, and the heat of formation at 316 K are -1.07 +- 0.07 and 42.09 +- 0.11 kc ...
