Rheological and small angle neutron scattering investigation of shear‐induced particle structures of concentrated polymer dispersions submitted to plane Poiseuille and Couette flowa)
Shear‐induced particle structures of rheologically well‐characterized concentrated polymer dispersions were investigated by small angle neutron scattering (SANS) in a wide range of shear rates. TheExpand

Shear and elongational flow properties of polypropylene meltsa)
The rheological properties of polypropylene melts were investigated in oscillatory shear flow, capillary rheometry, and uniaxial elongation at constant tensile stress as well as constant strain rate.Expand

Rheological Properties of a Partially Molten Polypropylene Random Copolymer during Annealing
Semicrystalline polymers exhibit a broad melting transition. This effect is due to the lamellar thickness distribution in the materials. The melting temperature T m (1) of a given lamella increasesExpand

The identification of element 108
The major problems in the investigation of the heaviest elements at the upper end of the periodic table are the small formation cross sections which are far below the nanobarn region and their short halflives of the order of milliseconds. Expand

Detection of hard photons with BaF2 scintillators
Abstract Large BaF 2 crystals have been used for hard photon detection. The response to γ-rays with energies up to 130 MeV has been measured by means of tagged photons. Experimental line shapes andExpand

Influence of energy summing of α-particles and conversion electrons on the shapes of α-spectra in the region of the heaviest nuclei
Abstract Measured α-decay spectra of the isotopes 215Th and 213Ra were used to investigate the influence of energy summing of α-particles and conversion electrons, and Auger electrons, respectively,Expand

Shear and elongational flow properties of fluid S1 from rotational, capillary, and opposed jet rheometry
Abstract Non-linear shear and elongational flow properties of the ternary fluid S1 have been compared to those of a binary solution with similar linear viscoelastic properties. In contrast to theExpand

Observation of the isotopes264108 and265108
The experiment having led to the discovery of first isotopes of element 108, as published previously in Short Notes to this Journal [1, 2] are described and discussed in a final paper.Two isotopes ofExpand

Rheological characterization of the fluid M1 and of its components
Abstract An opposing jet rheometer was used to measure the apparent elongational viscosity of fluid M1. The behaviour in simple shear was characterized by using different types of rotationalExpand
