this paper focused on a novel method of electroless plating ruthenium (ru) on solid or porous substrates like porous stainless steel (pss) discs or ceramic tubes. a novel complexing plating bath of ru was developed. it is proven that ru can be deposited directly on these substrates by the bath at a temperature of 328 k and strong alkaline environment. tga, sem, edx and xrd confirmed the success...

background: the entrance of toxic compounds into wastewater treatment plants (wwtps) can induce disorder in their biological units. therefore, it is necessary to determine the sources of toxic wastewaters. in this study, the toxicity of the wastewater of 3 metal plating industries was assessed using sequencing batch reactor (sbr) bacteria. methods: to obtain the 1-1000 ml/l concentrations, the ...

Electroless nickel plating is a widely used plating method in many industries. The usability of the coating is, however, restricted by the control problems related to the electroless nickel plating process. To ensure deposit quality, the transcendent properties of electroless nickel deposit should be accurately controlled during plating, which is challenging because of the spontaneous, unstable...

The aim of this study was to characterize stem and progenitor cell populations from the equine superficial digital flexor tendon, an energy-storing tendon with similarities to the human Achilles tendon, which is frequently injured. Using published methods for the isolation of tendon-derived stem/progenitor cells by low-density plating we found that isolated cells possessed clonogenicity but wer...

PURPOSE This study was conducted to examine a biomechanical model and to help answer fundamental questions that relate to rigid plate fixation in the maxilla. Specifically, we sought to elucidate the principal strain patterns generated in the maxilla secondary to masticatory forces as well as the amount of permanent deformational changes incurred due to these loading forces. MATERIALS AND MET...

Background and purpose: Heavy metals such as chromium, nickel, and zinc are the most common contaminants found in the plating wastewater that cause environmental pollution due to non-biodegradability. This study investigated the removal of chromium, nickel, zinc and turbidity from wastewater of plating and galvanized industries by electrocoagulation technology. Material and methods: This study...

Colony counting by spreading bacterial suspensions on plating media by various techniques is of general concern. Comparative studies between hand plating (Drigalski-spatula technique) for different time intervals and spiral plating resulted in significant differences in colony counts. Lower counts of Gram-negative bacteria were obtained by using hand plating for more than 10s, compared with sho...
