Al-Ansab and the Dead Sea: Mid-MIS 3 archaeology and environment of the early Ahmarian population of the Levantine corridor.
Autor: Jürgen Richter, Thomas Litt, Frank Lehmkuhl, Andreas Hense, Thomas C Hauck, Dirk F Leder, Andrea Miebach, Hannah Parow-Souchon, Florian Sauer, Jonathan Schoenenberg, Maysoon Al-Nahar, Shumon T Hussain
Publikováno v: PLoS ONE, Vol 15, Iss 10, p e0239968 (2020)
Our field data from the Upper Palaeolithic site of Al-Ansab 1 (Jordan) and from a pollen sequence in the Dead Sea elucidate the role that changing Steppe landscapes played in facilitating anatomically modern human populations to enter a major expansi

A Model-Independent Radio Telescope Dark Matter Search
Autor: Aya Keller, Sean O’Brien, Adyant Kamdar, Nicholas M. Rapidis, Alexander F. Leder, Karl van Bibber
Publikováno v: Journal of Physics: Conference Series. 2156:012026
A novel search technique for ultralight dark matter has been developed and carried out over a narrow range in L band, utilizing the recent Breakthrough Listen public data release of three years of observation with the Green Bank Telescope. The search

Dielectric response (0.4–250 μm) of thin films as a function of structure and composition
Autor: P. Domens, F. Leder, M. Cadene, M. Lumbreras-Ginter
Publikováno v: Solar Energy Materials. 3:425-440
Cd 1−x Zn x S polycrystalline layers were prepared by means of the thermal evaporation of suitable CdZnS solid solutions ( 0⪕x⪕0.2 ) on different substrates. The ZnS concentration dependence on the crystallinity and the dielectric function has

Effect of fluid-phase equilibria on ethylene-vinyl acetate copolymer composition
Autor: F. Leder, M. J. Wisotsky
Publikováno v: Journal of Polymer Science Part A-1: Polymer Chemistry. 10:447-454
Literature reports indicate that in the copolymerization of ethylene with vinyl acetate, the reactivity ratios change with pressure. There is general agreement that reth ≅ rvac ≅ 1 at high pressure, but deviations reportedly occur at low pressure

The absorption of CO2 into chemically reactive solutions at high temperatures
Autor: F. Leder
Publikováno v: Chemical Engineering Science. 26:1381-1390
Simultaneous absorption and chemical reaction of carbon dioxide in potassium carbonate-bicarbonate buffer solutions was measured, at 80°C. Rates of absorption were catalyzed by addition of water soluble amines to the solution. Addition of methyl-ami
