Powder samples were dispersed in saturated ethanol and bath sonicated for 15 s before transferring in to fraction cell. The refractive indices of kanamycin (1.67) (for kanamycin-only and kanamycin-rifampicin combination powder) and rifampicin (1.61) were used to automatically measure the particle volumetric diameters of the…

have been avoided if correct gun laws had been around. For instance, on June 20, 2012, James Eagan Holmes unleashed a barrage of firepower upon the audience in a movie theater in Aurora, Colorado.

Both groups have some good ideas, but the general public needs to understand that the answer isn’t less guns. Being an avid trap shooter and hunter myself, I…

Abstract: We describe the successful synthesis of Polypyrrole-Gold nanocomposites (PPy-Au NCs) by the chemical oxidative polymerization of pyrrole with ferric chloride as an oxidizing agent, in the presence of a colloidal suspension of gold nanoparticles. Gold nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier…

Ethyl vinyl ether was used to protect –OH on glycidol based on a literature reported protocal.59 In a typical procedure, 0.675 mol glycidol and 200 mL ethyl vinyl ether were loaded in a round-bottom flask, to which 1.25 g TsOH was then added. The reaction was allowed to proceed at room temperature (RT) for 3h. The resulting mixture was then purified by washing with 100 ml saturated aqueous solution of NaHCO3 for 3 times. The organic layer obtained was dried by MgSO4. After filtration of MgSO4,…
