A. Mohammadi A.H. Azizi,

Surface finishing is one of the most significant steps in industries which are engaged with surface quality. Finishing by magnetic field is a new method of surface finishing. In this process, machining is executed in mechanical way and semi-homogeneous abrasive slurry performs finishing of surfaces. Needed force to grind surfaces is made by magnetic field. Therefor this method is considered as ...

In This applicable research, investigating absorption of process ofErythrosine dye on Copper oxide Nano particles Adsorbent was studied. First, prepared dyeconcentrations of 6, 8 and 12 mg L-1 and then effects of parameters such as concentrations ofinitial dye, time and pH on dye absorption efficiency were investigated.The dyeconcentrations in different samples were measured via spectrophotomet...

This paper represents the uniform distribution of particles in a mixture Silicon Nitride and Hexagonal Boron using Ball milling process. Here, novel attempt is made to quantify terms Experimental Fraction Observations. The effects process parameters on Average Particle Size Observations were studied. Taguchi Methodology was used for Design Experiments this study. Optimal factor level settings c...

Introduction: Pediments are vitally important geomorphological units. Desert pavement feature is used for their classification. The characteristics of desert pavements are a function of geomorphological conditions and have unique properties in terms of different granulation parameters. A variety of methods are employed to determine granulation. The most common method is the sieving test, in whi...

Poly-(alkylcyanoacrylate) ester particles have been used for the preparation of different formulations ranging from ophthalmic delivery systems to cancer chemotherapy carriers in clinic. The aim of this study was to prepare and characterize poly-(methyl ethyl cyanoacrylate) (PMECA) particles containing 5-aminosalicylic acid (5-ASA). PMECA particles were prepared using the inverse emulsification...
