Since the first gold liquid crystal was described in 1986, much effort has been done to prepare new compounds bearing this property. The review deals with the last results obtained in this new century. Gold(I) has a strong affinity to give linear co-ordination and metal-metal interactions, which produce a rich supramolecular chemistry, and can promote the behavior as liquid crystal. Therefore, ...

Nematic liquid crystals make promising chemoresponsive systems, but their development is currently limited by extensive experimental screening. Here we report a computational model to understand and predict orientational changes of surface-anchored nematic liquid crystals in response to chemical stimuli. In particular, we use first-principles calculations to evaluate the binding energies of ben...

A liquid metal target is one of the options for the pion production target of a n-factory. The interaction between a liquid metal and a proton beam were observed with static mercury as well as with a free mercury jet and up to 4 10 protons/bunch. The experimental method for investigating the magneto-fluid-dynamic effects of a high-velocity liquid metal in a high magnetic field magnet has been v...

The blanket system is one of the most important components in a fusion reactor because it has a major impact on both the economics and safety of fusion energy. The primary functions of the blanket in a deuterium/tritium-fueled fusion reactor are to convert the fusion energy into sensible heat and to breed tritium for the fuel cycle. The liquid-metal blanket concept requires an electrically insu...

PURPOSE Small-animal studies require images with high spatial resolution and high contrast due to the small scale of the structures. X-ray imaging systems for small animals are often limited by the microfocus source. Here, the authors investigate the applicability of liquid-metal-jet x-ray sources for such high-resolution small-animal imaging, both in tomography based on absorption and in soft-...

The ultrasound Doppler velocimetry (UDV) is an innovative and non-invasive method to determine the velocity in liquid flows. Main advantages are the ability to investigate flows of opaque liquids and to deliver complete velocity profiles in real-time [1,2]. Therefore, the intention to apply this measuring technique to liquid metal flows is obvious with respect to the situation that until today ...

Introduction: The partitioning of oxygen between silicates and liquid Fe-rich metallic alloy is a key factor in controlling chemical differentiation during core formation in terrestrial planets [1]. This is because oxygen partitioning determines the oxygen fugacity uniquely for a given bulk composition and therefore controls the partitioning of Fe and other siderophile elements during core form...

Metamaterial absorbers can provide good solutions for radar-cross-section (RCS) reduction. In spite of their attractive features of thinness, lightness, and low cost, resonant metamaterial absorbers have a drawback of narrow bandwidth. For practical radar applications, wideband absorbers are necessary. In this paper, we propose a wideband-switchable metamaterial absorber using liquid metal. In ...

A liquid-metal based spiral magnetohydrodynamic (MHD) micropump is proposed in this work. The micropump was fabricated in a polydimethylsiloxane (PDMS)-glass hybrid microfluidic chip. This pump utilized two parallel liquid-metal-filled channels as electrodes to generate a parallel electrical field across the pumping channel between the two electrodes. To prevent contact and cross contamination ...
