The manuscript is a comparison between antibacterial effect of carbones nanotubes (multy walls) functionalized and nonfunctionalised in the presence of silver nanoparticles.The nanotubes functionalization is performed according a chemical procedure introducing COOH groups. Surface analysis type Scaning electron microscopy (SEM) and transmission electron microscopy (TEM) presents topographical aspects of nanotubes. The paper signals new trends in

This paper presents the results regarding the electrochemical stability and surface analysis of a new alkyd paint with low content of volatile organic compounds in comparison with a conventional alkyd paint. The alkyd films were realized on carbon steel substrate. Dry films thickness in 30–35 μm range was obtained. The experimental tests were carried out in 3% NaCl solution at the 25 °C temperature. The electrochemical techniques (electrochemical

The grateful aim of the paper is to evaluate the heavy metal of temporary teeth collected from area with various environmental pollution. It is a new approach, trying to correlate the amount of heavy metals determined with inductively plasma mass spectroscopy (ICP-MS) in enamel and dentine with hydrophilic properties at interface and the type of teeth. The paper established specific correlation of the teeth type and the amount of heavy metals indicating

A new titanium base Ti–6Al–4V–1Zr alloy covered with hydroxyapatite or bovine serum albumin/hydroxyapatite was characterized in this paper in order to be used as implant material. Following techniques were used: linear polarization, electrochemical impedance spectroscopy, scanning electronic microscopy, Fourier transform infrared spectroscopy and atomic force microscopy. For HA or . covered alloy, the electric equivalent circuit contains two

The papers is focused on TiO2 nanotubes elaboration and characterization, taking into account that monitoring elaboration condition seems to be a way to obtain nanotubes with various dimensions and various potential applications. Over the last decade various techniques were performed in order to get TiO2 nanostructure and anodizing is a chip and convenient one. Changing anodizing parameters as voltage, pH electrolyte compositions and time of electrolysis

The present paper is focused on comparative behaviour of various nanotubes growth on Ti6Al7Nb alloy using electrochemical procedure. The anodizing method under controlled conditions was performed in two kinds of electrolytes as following: a mixture of fluoride salts as inorganic solution (NH4)2SO4+ NH4F 0.5 wt%), and a hybrid inorganic + organic components as The obtained surface nanostructures were investigated with an Environmental Scanning Electron
