We demonstrate a new method of aligning liquid crystals along polymer surfaces that are printed vertical to the focal plane using direct laser writing. The method is based on nanogrooves that are imprinted into surfaces of polymer structures and provide robust, reliable, repeatable, and well-control ...

Color centers in hexagonal boron nitride (hBN) have been emerging as a multifunctional platform for various optical applications including quantum information processing, quantum computing and imaging. Simultaneously, due to its biocompatibility and biodegradability hBN is a promising material for b ...

New quasicrystals with rare-earth elements and Li are synthesized with the selfflux method. The starting composition involves 62.8 at.% Zn, 28.6 at.% Mg, 3.6 at. % rare-earth and 5% Li. Alternatively, 66 at.% Zn, 24.8 at.% Mg, 3.9 at.% rare-earth and 5.3% Li can be used. Both syntheses result in qua ...

Of our interest are frustration-driven pattern generating mechanisms in systems which in bulk equilibrium display spatially homogeneous long-range orientational order in absence of perturbations. As testbed material, we select thermotropic nematic liquid crystals. In bulk, they exhibit weakly discon ...

This study presents the atomic structure solution of a primitive icosahedral Zn70.83Mg20.31Er8.86 quasicrystal using in-house X-ray diffraction and the Ammann–Kramer–Neri tiling framework. The structural model with 344 parameters refined against 2674 Bragg peaks achieves a reasonable R factor of 0.1 ...

We have determined the crystal structure and the magnetic state of the CeFe9Si4 intermetallic compound. Our revised structural model (fully ordered tetragonal unit cell, I4/ mcm) agrees with the previous literature report, except for some minor quantitative differences. Magnetically, the CeFe9Si4 un ...

The all-optical control of light has been explored in hard matter, but to control light by light in soft matter is a major experimental and conceptual challenge that remains largely unexplored. We propose and verify experimentally and numerically that nanosecond light pulses can be controlled by lig ...

In this study, we investigate the scandium-containing Sc-Hf-Nb-Ta-Ti-Zr system of refractory high-entropy alloys (HEAs). Using the arc-melting method, we synthesized nine equimolar alloys (five 4-, three 5- and one 6-component), with all of them containing Sc. The alloys were characterized by XRD, e ...
