Effect of the change of crystallinity and micro texture of electroplated copper thin films by annealing on the stressinduced migration was investigated experimentally and theoretically. The micro texture of electroplated copper thin films changed drastically as a function of their electroplating conditions and the annealing temperature after the electroplating. The crystallinity of the electrop...

An infrared (IR) temperature sensor module developed for the detection of defects in a metal plate is modified for defect detection in a pipe. A module giving close sensor arrangement and maintaining a constant distance between sensor and measured object is developed and utilized in the present modification of the IR thermographic device. The defect detection performance is experimentally inves...

Wastewater treatment issues are extremely important for humanity. Their consideration becomes more than a necessity, a responsibility and every producer must improve their treatment processes. The efficiency increasing of these processes has been done in two ways: 1. by technological way various types of treatment were developed during the past years and this domain has almost no technological ...

As a consequence of modernization, industry is spread in the whole world, one of the industries that producing a wastewater as a by-product, iron and steel industry. The result is a huge amount of wastewater that contaminated with iron and steel. Biosorption techniques especially with a natural low cost adsorbent material, namely chicken eggshell is gaining an important goal for treating with a...

Algae biosorption is an ideal wastewater treatment method when coupled with algae growth and biosorption. The adsorption and bioaccumulation of strontium from simulated nuclear wastewater by Scenedesmus spinosus were investigated in this research. One hundred mL of cultured S. spinosus cells with a dry weight of 1.0 mg in simulated nuclear wastewater were used to analyze the effects on S. spino...

In this study, aerobic digestion of tannery industry wastewater was carried out using mixed culture obtained from common effluent treatment plant treating tannery wastewater. The effect of pH, temperature, inoculum concentration, agitation speed and initial substrate concentration on the reduction of organic matters were found. The optimum conditions for COD reduction was found to be pH 7 (60%)...

The textile industry is one of the biggest industries in the world and its wastewater is one of the most important threats to the environment and human health. In this study, the ability of Haloarcula sp. IRU1 to produce poly(3-hydroxybutyrate) (PHB) was investigated using a basal salts medium. Different factors like textile wastewater, yeast extract, and KH2PO4 (as carbon, nitrogen, and phosph...

The main aim of this work was to study the removal efficiency of Pb from synthetic and industrial wastewaters by using biomass fly ashes. The biomass fly ashes were produced in a biomass boiler of a pulp and paper industry. Three concentrations of Pb(2+) were tested in the synthetic wastewater (1, 10 and 1000 mg Pb/L). Moreover, two different wastewaters were collected in an industrial wastewat...
