X-ray computed tomography to observe the presence of water in macropores of cementitious materials

RILEM Technical Letters
Corrosion of steel reinforcement in concrete is a common degradation mechanism occurring in infrastructures worldwide. Even though extensive research has been conducted over the last decades to accurately predict the influence of steel corrosion on ...

Demonstration of coded-aperture fast-neutron imaging based on Timepix detector

, 2020
Localization of radioactive hot spots is an important issue for nuclear industry (decommissioning, waste management, radiation protection) as well as for Homeland Security applications (non-proliferation of special nuclear material and management of ...

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2

Nature Communications, 2016
Whilst terahertz optical spectroscopy allows for the study of coupled spin and lattice excitations, it is limited in momentum space. Here, the authors use inelastic x-ray scattering to demonstrate strong magnon-phonon coupling and electromagnon ...

Extrinsic Limitations of Stealthy Hyperuniform Devices

Advanced Optical Materials, EarlyView.
Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

Flat-band hybridization between f and d states near the Fermi energy of SmCoIn5

npj Quantum Materials
We present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn5. We find broad agreement with previously published studies of LaCoIn5 and CeCoIn5 1,2, confirming that the Sm 4f electrons are ...

Neutron Bragg edge imaging for strain and texture characterization of steel-copper multi-material obtained by laser powder-bed fusion

Materials & Design
Bragg edge imaging has been applied to multi-material laser powder-bed fusion (M2LPBF) samples of 316 L stainless steel and CuCrZr. A multilayer sample with interfaces perpendicular to the building direction and a bilayer sample with a parallel interface
