Abstract The development of hexaferrite nanoparticles is scrutinized as potential sorbents for the removal chromium (Cr) ions from aqueous chromium-containing solutions in a batch adsorption experiment. transition metal Co doped BaFe 12 O 19 compounds (BHF) have been synthesized successfully via citrate auto combustion technique. structure, surface morphology and magnetic properties samples wer...

Purpose: To compare rate of change in IOP with and without air bubbles in the anterior chamber (AC). Methods: Enucleated porcine eyes were infused with Balanced Salt Solution (BSS) at 10μl/min. In one experiment, 5 eyes each were injected with 0.15 or 0.30ml bubbles without prior removal of aqueous humour while 5 controls were not injected. In another experiment, 9 eyes were injected with 0.30m...

in this paper electrical conductivity measurements and optical investigations takes place in aot/ heptane/ (water or aqueous) systems. the water in oil system prepared with adding water in 50% by weight of aot/ heptane solution.  in other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) potassium hydroxide and water were used. in each phase, the trend of the electrica...
