Liquid tin (Sn) is a promising coolant for liquid divertor concepts. However, its material compatibility with structural materials is an important issue. The purpose of the present study is to investigate corrosion resistance of Al-rich steel NTK04 L

A cholesteric liquid crystal (CLC) is a self-assembled photonic crystal formed by rodlike molecules, including chiral molecules, that arrange themselves in a helical fashion. The CLC has a single photonic bandgap and an associated one-colour reflecti

We analyzed the local nanostructure in binary mixtures of rod- and bent-shaped molecules, n-pentyl-4-cyanobiphenyl (5CB) and 1,3-phenylene bis[4-(4-n-octyloxyphenyliminomethyl) benzoates] (P-8-OPIMB), respectively, using small- and wide-angle X-ray m

We found a subphase with a six-layer periodicity which appears between the ferroelectric SmC(*) and the antiferroelectric SmC(A)(*)(q(T) = 0) phases. The six-layer periodic structure is directly determined by the microbeam resonant x-ray scattering m

We studied the local layer structure in the B2 phase of bromine-substituted bent-core liquid crystals in the cell geometry using microbeam resonant x-ray scattering. In the homochiral state of B2 phase, the 3/2 order satellite peak was observed only

The authors have observed highly circularly polarized electroluminescence from organic light-emitting diodes (OLEDs) using wide-band reflector consisting of three-layered left-handed polymeric cholesteric liquid crystal (PCLC) films. By simply attach

We studied the details of a local layer structure in the B2 phase of bromo-containing bent-core liquid crystals mixed with a small amount of chiral molecules using microbeam resonant X-ray scattering. In this measurement, we detected the 1???0.2 orde

A bromo-substituted chiral smectic liquid crystal was synthesized for the purpose of the study on the sub-phases of the chiral smectic C* (SmC* variants) using resonant X-ray scattering. The introduction of a bromo atom was found to have a significan
