The present paper deals with a hydrazine mediated synthesis of high surface area and thermally stable N-doped zirconium titanium mixed oxide with enhanced photocatalytic activity towards reduction of selenium (VI) to metallic Se under visible light. Materials were synthesized at pH 1⁄4 2 by varying the hydrazine concentration and characterized by XRD, TEM, BET method, XPS, Raman spectroscopy an...

OBJECTIVE The purpose of this study was to verify the antibacterial performance and cell proliferation activity of zirconium (Zr)-carbon (C)-nitride (N) coatings on commercially pure titanium (Ti) with different C contents. MATERIALS AND METHODS Reactive nitrogen gas (N(2)) with and without acetylene (C(2)H(2)) was activated by Zr plasma in a cathodic-arc evaporation system to deposit either ...

Ions are released from all metals after implantation in the body through processes of corrosive and mechanical wear. The aim of this study was to investigate whether serum metal ion levels are raised in patients following total knee arthroplasty. Serum levels of chromium, cobalt, aluminium, molybdenum and zirconium were measured in two groups of patients at a minimum of 3 years after knee arthr...

Abstract The paper presents the kinetics of Zn (II) ions adsorption as well its dependence a function pH on nanostructured zirconium phosphate and composites with silica titania. phosphate-containing were obtained by mechanical processing in Pulverisette-7 (Fritsch Gmbh) mill. characterized heterogeneous surface coverage gel or titanium oxides. Zinc studies these adsorbents showed practically c...

Zirconium and its alloys have many applications in orthopedic medicine and compared to stainless steel, titanium and other metals used in the manufacture of implants has higher strength and corrosion resistance. Research shows that the method of preparation and surface modification before coating process has a significant impact on improving the metal implants among which include the sandblasti...

The study presents a possible mechanism to produce carbides and diborides of transition metals, such as titanium, vanadium, chromium zirconium. carbothermal synthesis metal has defined the direct dependence between thermodynamic stability oxides temperature range reduction onset (the stronger oxide, higher value is). It reaches 2000-2100, 1500-1600, 1300-1400 2100-2200°C for TiC, VC 0,88 , Cr 3...
