Crystal orientation-dependent etching and trapping in thermally-oxidised Cu<sub>2</sub>O photocathodes for water splitting Open
Crystal orientation-dependent etching, charge-carrier trapping behaviour, and performance of single-crystal photocathodes are enabled by ammonia solution etching of thermally-oxidised Cu 2 O.

Texture, microstructure and mechanical anisotropy in <span>SLM</span> processed superalloys Open
Samples of Nickel‐based (IN738LC and Hastelloy X) and Cobalt‐based (Mar‐M509) alloys were built by selective laser melting (SLM). To evaluate the anisotropy in the mechanical behavior of the material due to layer‐wise build up, specimens w…

Laser-induced asymmetric faceting and growth of a nano-protrusion on a tungsten tip Open
Irradiation of a sharp tungsten tip by a femtosecond laser and exposed to a strong DC electric field led to reproducible surface modifications. By a combination of field emission microscopy and scanning electron microscopy, we observed asy…

Crystal orientation measurements using SEM–EBSD under unconventional conditions Open
Electron backscatter diffraction (EBSD) is a micro-analytical technique typically attached to a scanning electron microscope (SEM). The vast majority of EBSD measurements is applied to planar and polished surfaces of polycrystalline bulk s…

Origin of magnetic fabrics in ultramafic rocks Open
The magnetic fabric of a rock, defined by the anisotropy of magnetic susceptibility (AMS), is often used as a tectonic indicator. In order to establish a quantitative relationship between AMS and mineral texture, it is important to underst…
