The angular distributions of prompt-fission γ-rays with respect to thedirection of fission fragments in the monochromatic “warm” neutron induced fissionof 235U have been studied. The fragments were detected with low-pressure positionsensitive multi-wire proportional counter and the gamma-rays with a plastic scintillators. [...]

In aqueous solution, diblock copolymers PMMA-b-PNIPAM having a short PMMA block and a long PNIPAM block form micelles with a PMMA core and a PNIPAM-rich shell. The same holds true for solutions in water containing small amounts of methanol. [...]

We report a combined polarized and unpolarized neutron diffraction study on a multiferroic Sr$_2$CoSi$_2$O$_7$ (SCSO) single crystal below and above the antiferromagnetic ordering temperature $T_N$ = 6.5 K. Unpolarized neutron diffraction measurements at 15 K confirm the melilite-type tetragonal $P\overline{4}2_1m$ space group as the parent structure of SCSO. [...]

Detailed investigation of Ba$_2$MnGe$_2$O$_7$ was performed in its low-temperature magnetoelectric state combining neutron diffraction with magnetization measurements on single crystals. In the paramagnetic state at 10 K, polarized neutron diffraction was applied to reveal the components of the susceptibility tensor. [...]

The pore structure of mudrocks is a key characteristic to evaluate flow behavior through these rocks. Although significant advances have been made to resolve pore characteristics, porosity evolution, or pore connectivity, there is still insufficient knowledge linking porosity evolution to flow and transport in mudrocks.
