A method of preventing the formation of barium sulfate scale deposited by aqueous produced or injection fluids having a pH below 7.5 which are recovered with or are used to recover petroleum from underground formations which comprises treating these aqueous fluids with a low molecular weight polyvinyl...
Commercially available bone cements are a two-component system: a powder and a liquid. The powder is made of PMMA beads, sometimes combined with different co-polymers, a polymerization initiator (e.g., benzoyl peroxide), and a radiographic contrast material (radiopacifier) like ...
This work aims to fabricate barium titanate (BaTiO3) nanoparticles and study the effect of adding different contents of BaTiO3 nanoparticles on the structural, optical, and electrical properties of PVC polymer matrices. The PVC/BaTiO3 nanocomposite films were characterized by X-ray diffraction, FT-...
Calculate the mass in grams of 0.640 moles of manganese(II) sulfate. Calculate the molar mass of zinc sulfate. Determine the formula and then calculate the MW ( molecular weight) of nickel(III) sulfate. Write the formula and calculate the molar mass of barium perchlorate...
Answer and Explanation:1 An osmometer is a device used to measure the concentration of solutes in a liquid. It can be used to estimate the molecular weight of a...
Other types of scales include calcium carbonates and sulfates, barium sulfate, and strontium sulfate. The costs related to scale deposition were estimated to be about 800 million $US in the United Kingdom, 9 billion $US in the USA, and 3 billion $US in Japan while the global cost amounted...
