In October 2008, a heavily corroded pendant was found during an excavation campaign in the historic district of Mainz, Germany, in an ancient dump. The reliquary pendant, made of gilded copper, is in the shape of a quatrefoil, also referred to as a phylacterion, and dates from the late 12th century. [...]

The aim of this work is to determine the neutron transmission of polycrystalline sampleswith a polychromatic neutron beam. The focus was to include the wavelengthdependent effects and to make a statement about their influence on the transmission.The transmission of neutrons through different materials was evaluated at differentthicknesses for a polychromatic spectrum. [...]

A series of low-temperature studies on LiNi$_{0.80}$Co$_{0.15}$Al$_{0.05}$O$_2$ 18650-type batteries of high-energy type with different stabilized states of fatigue is carried out using spatially resolved neutron powder diffraction, infrared/thermal imaging, and quasi-adiabatic calorimetry. In-plane distribution of lithium in the graphite anode and frozen electrolyte in fully charged state is determined non-destructively with neutron diffraction and correlated to the introduced state of fatigue. [...]

The electrochemical reduction of CO2 is a pivotal technology for the defossilization of the chemical industry. Although pilot-scale electrolyzers exist, water management and salt precipitation remain a major hurdle to long-term operation. [...]

The former neutron monochromator shielding of the FLEXX-instrument at the research reactor BER-II (Berlin) will be moved to the research reactor in Munich (FRM-II) in order to reuse it for a new cold-neutron triple-axis spectrometer. The neutron flux at the monochromator position at FRM-II is roughly 20 times higher compared to its former application. [...]

Emission of prompt gamma rays following (n,n'), (n,p) and (n,alpha) reactions induced by irradiation of a calcium carbonate (CaCO3) sample with a beam of fission neutrons was investigated with a modified version of the FaNGaS (Fast Neutron-induced Gamma-ray Spectrometry) instrument operated at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching. The neutron spectrum has an average energy of 2.30 MeV and at sample position the fast neutron flux was (1.13 +/- 0.04) x 10(8) cm(-2) s(-1). [...]

Generally, edge crack of rolled magnesium alloy sheets initiates in the RD (rolling direction)-ND (normal direction) plane and then propagate in the RD-TD (transverse direction) plane. Hence, the Mg-2Zn-1.5Mn (ZM21) alloy sheets with and without crack notch were designed to carry out in-situ tensile experiments under 150 °C (the same temperature of rolling), with the aim to understand their crack propagation mechanism. [...]

We report neutron depolarization measurements of the suppression of long-range ferromagnetism and the emergence of magnetic irreversibilities and spin freezing in CePd$_{1-x}$Rh$_x$ around $x^*\approx0.6$. Tracking the temperature versus field history of the neutron depolarization, we find clear signatures of long-range Ising ferromagnetism below a Curie temperature $T_{\rm C}$ for $x=0.4$ and a spin freezing of tiny ferromagnetic clusters below a freezing temperature $T_{\rm F1}$ for $x>x^*$ [...]
