This paper describes a nickel-based cellular material, which has the strength of titanium and the density of water. The material's strength arises from size-dependent strengthening of load-bearing nickel struts whose diameter is as small as 17 nm and whose 8 GPa yield strength exceeds that of bulk nickel by up to 4X. The mechanical properties of this material can be controlled by varying the nanometer-scale geometry, with strength varying over the range 90-880 MPa, modulus varying over the range 14-116 GPa, and density varying over the range 880-14500 kg/m(3). We refer to this material as a "metallic wood," because it has the high mechanical strength and chemical stability of metal, as well as a density close to that of natural materials such as wood.

Pressure Dependence of Molar Volume near the Melting Point in Benzene Yurtseven, Hasan Hamit (Tsinghua University Press, 2007-10-01) The pressure dependence of the molar volume was at constant temperatures close to the melting point in benzene. The molar volume of benzene was calculated using experimental data for the thermal expansivity for constant temperatures of 25°C, 28.5°C, 40°C, and 51°C at various pressures for both the solid and liquid phases. The predictions are in good agreement with the observed volumes in both the solid and liquid phases of benzene. The predicted values of the molar volume for a constant temperature of 28.5°...
Application of Electric Resistance Heating Method on Titanium Hot Forming at Industrial Scale Ozturk, Fahrettin; Ece, Remzi Ecmel; Polat, Naki; Koksal, Arif; Evis, Zafer; Sheikh-Ahmad, Jamal Y. (Springer Science and Business Media LLC, 2016-11-01) In this study, hot forming of DIN WL 3.7024 commercially pure titanium with a sheet thickness of 0.6 mm was performed by electric resistance heating. The sheet materials were heated at 600, 650, and 680 A degrees C and then hot formed with an industrial press. Grain size measurement and XRD analysis were performed for each forming temperature in order to investigate microstructure and phase changes. Results indicate that no microstructural changes have occurred at the mentioned temperature range. It was con...
Afterglow, TL and OSL properties of Mn2+-doped ZnGa2O4 phosphor Luchechko, Andriy; Zhydachevskyy, Yaroslav; Ubizskii, Sergii; Kravets, Oleh; Popov, Anatoli I.; Rogulis, Uldis; Elsts, Edgars; Bulur, Enver; Suchocki, Andrzej (Springer Science and Business Media LLC, 2019-07-02) Zinc gallate (ZnGa2O4) spinel ceramics doped with Mn2+ ions was prepared by a solid-state reaction at 1200 degrees C in air. Manganese concentration was equal to 0.05 mol.% of MnO with respect to ZnO. Ceramics produced in this way show an efficient green emission at about 505 nm under UV or X-ray excitations, which is caused by Mn2+ ions. This green emission is observed also as a relatively long afterglow (visible to the naked eye in the dark for about one hour) after switching-off the X-ray excitation. Tim...
Nanoparticle self-assembly at the interface of liquid crystal droplets Rahimi, Mohammad; Roberts, Tyler F; Armas-Pérez, Julio C; Wang, Xiaoguang; Büküşoğlu, Emre; Abbott, Nicholas L; de Pablo, Juan Jose (Proceedings of the National Academy of Sciences, 2015-04-28) Nanoparticles adsorbed at the interface of nematic liquid crystals are known to form ordered structures whose morphology depends on the orientation of the underlying nematic field. The origin of such structures is believed to result from an interplay between the liquid crystal orientation at the particles' surface, the orientation at the liquid crystal's air interface, and the bulk elasticity of the underlying liquid crystal. In this work, we consider nanoparticle assembly at the interface of nematic drople...
Blue-phase liquid crystal droplets Martinez-Gonzalez, Jose A.; Zhou, Ye; Rahimi, Mohammad; Büküşoğlu, Emre; Abbott, Nicholas L; de Pablo, Juan Jose (Proceedings of the National Academy of Sciences, 2015-10-27) Blue phases of liquid crystals represent unique ordered states of matter in which arrays of defects are organized into striking patterns. Most studies of blue phases to date have focused on bulk properties. In this work, we present a systematic study of blue phases confined into spherical droplets. It is found that, in addition to the so-called blue phases I and II, several new morphologies arise under confinement, with a complexity that increases with the chirality of the medium and with a nature that can ...
