In this work, we have studied the methods of electrochemical processing materials in order to give them new functional properties. Experimental data on production corrosion-resistant coatings based Zn-Ni and Zn-Co alloys from ammonium oxalate electrolytes study their protective properties are presented. The questions carbon nanomaterials by anodic exfoliation graphite sulfuric acid considered. ...

background. repairing aged composite resin is a challenging process. many surface treatment options have been proposed to this end. this study evaluated the effect of different surface treatments on the shear bond strength (sbs) of nanofilled composite resin repairs. methods. seventy-five cylindrical specimens of a filtek z350xt composite resin were fabricated and stored in 37°c distilled water...

Textiles are commonly composed of natural and synthetic fibers for normal applications [...]

Treated sea water is the most significant source of water and surfactant floods. The various chemicals employed in treatment plants should be compatible with surfactant systems. Based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...
