ObjectiveA novel copper-bearing titanium alloy (Ti–Cu) was fabricated for dental application that is expected to efficiently restrain the growth of bacteria and discourage biofilm formation. The aim of this study was to investigate both the antibacterial activity and biofilm inhibition of Ti–C...

The joint with 1.0mm Cu66V34 filler metal produced a large amount of unmelted V alloy, weakening the joining quality of Ti/Cu joint. Due to the decreased thickness of filler metal, the melting quantity of Ti increased notably in the joint with 0.5mm Cu66V34 alloy, resulting in the formation of T...

Microstructure, electrochemical and wear behaviour of different Titanium-copper biomedical alloys (Ti-xCu, x = 3, 7.1 and 12%wt) obtained by powder metallurgy for dental implant applications have been analysed in artificial saliva and compared to Ti cp. Copper in the alloy increases the amount o...

Commercially pure titanium (CP-Ti), used as oral implants, is often populated by various bacterial colonies in the oral cavity. These bacteria can cause Peri-implantitis, leading to loss of bone tissue and failure of implants. With the increased awareness of antibiotic resistance, research has b...

Strontium niobates with different crystalline structure and morphology have been prepared via a hydrothermal method and applied as a support for ruthenium catalyst in ammonia synthesis. The sample synthesized with a nominal Sr/Nb = 2.0, having a pure Sr2Nb2O7 crystalline phase and specific surfa...

Single crystals of Cs8Nb22O59 and Rb8Nb22O59 have been grown by pulling from melts contained in platinum crucibles. The two materials are shown to be isomorphous and to exhibit strikingly different physical behaviour. Cesium niobate is a stable material, and some dielectric and optical data are ...

Hydrogen evolution from photocatalytic decomposition of water has been studied over cesium-loaded potassium niobate photocatalysts. Various photocatalyst supports and loading metals were used to obtain an active photocatalyst on the hydrogen evolution. The effect of additives in photoreaction as...

The antiferroelectric material Cs2Nb4O11 transforms at 165 °C from a low-temperature, antiferroelectric phase in space group Pnna to a high-temperature, paraelectric phase in space group Imma; the latter structure has been determined by single-crystal X-ray diffraction. The high-temperature lat...

Photoluminescence properties and relaxation dynamics of electronic excitations in cesium vanadate CsVO3 have been studied upon pulse laser excitation in the wide temperature range of 6.5–300 K. A vibronic structure observed in low-temperature PL spectra is considered and interpreted. Peculiarit...

A new cesium uranyl niobate, Cs9[(UO2)8O4(NbO5)(Nb2O8)2] or Cs9U8Nb5O41 has been synthesized by high-temperature solid-state reaction, using a mixture of U3O8, Cs2CO3 and Nb2O5. Single crystals were obtained by incongruent melting of a starting mixture with metallic ratio=Cs/U/Nb=1/1/1. The crys...

The compound cesium niobate, Cs2Nb4O11, is an antiferroelectric, as demonstrated by double hysteresis loops in the electric field versus polarization plot. The crystal structure refinement by X-ray diffraction at both 100 and 297 K shows it to have a centrosymmetric structure in point group mmm ...

Thin chromium and tellurium superlattice reactants with individual layer thickness ranging from a few Angstrom to thousands of Angstrom were deposited on (100)-Si substrate and the reactions were investigated with ex-situ and in-situ X-ray powder diffraction and X-ray reflectometry. The number o...

We present a detail study of the effect of excess metal atoms on the magnetic properties of Cu1+xCr2+yTe4 at 2–400 K. With the increase in x=0–1 and y

It is important to spintronics to achieve fully-spin-polarized magnetic materials that are stable and can be easily fabricated. Here, through systematical density-functional-theory investigations, we achieve high and even full spin polarization for carriers in the ground-state phase of CrTe by a...

Enhancing the efficiency of thermoelectric materials has been practiced extensively by either improving the power factor or reducing the lattice thermal conductivity. Magnetism, and the magnetic moment–charged carrier interactions, has been suggested to enhance the efficiency of some compounds....

We investigate magnetic anisotropy and magnetization reversal mechanism in chromium telluride thin films grown by molecular beam epitaxy. We report existence of strong perpendicular magnetic anisotropy in these thin films, along with a relatively strong second order anisotropy contribution. The ...

Chromium nitride (CrN) synthesized by heating at 550 °C under a continuous stream of ammonia has been investigated as anode material for lithium electrochemistry. Due to its low lithium insertion potential, Cr is an attractive material for lithium–ion battery application, but the usual volume ...

The purpose of this work was to theoretically and experimentally study the reactions that occur during low-pressure nitriding. A series of specimens made of 42CrMo4 and 41CrAlMo7 and C22 steels were low-pressure nitrided. The structure of the materials, the hardness and the thickness of the nitr...

Chromium catalysts were prepared by the saturating chemisorption of chromium(III) acetylacetonate (Cr(acac)3) at 200 °C on alumina and on alumina that had been surfaced with aluminum nitride. According to elemental analysis, infrared spectroscopy, and electron spin resonance spectroscopy, chemi...
