Most of the solution properties of PMEMA were determined with methyl ethyl ketone (MEK) (Reanal, Hungary) and tetrahydrofuran (THF) (VEB Laborchemie Apolda, German Democratic Republic) as solvents. Both solvents were reagent grade and distilled on laboratory .columns; to THF, cuprous chloride ...
One-pot synthesis of antiviral acyclovir and other nucleosides derivatives using doped natural phosphate as lewis acid catalyst. Natural phosphate doped with iodine or potassium iodide is an active catalyst for the one-pot synthesis of acyclonucleosides. To demonstrate the utility of... HB Lazrek,...

Most of the studies demonstrate that MTA is not soluble or presents low solubility when immersed in solution. MTA exhibits adequate sealing and has limited antimicrobial effect against some microorganisms. MTA might cause dental discoloration, which can compromise aesthetics. The amount of heavy metals...
In the beginning, about 0.1 M of potassium iodide was dissolved in deionized water. Subsequently, to measure the ultrasonic effect, the various MP systems (MP/CN and MP-flavonoid/CNs) were treated with a 6-minute ultrasonic treatment [11]. The solution was finally characterized by its ...
This is confirmed by quenching experiments with acrylamide, cesium chloride and potassium iodide. The copper–dioxygen system at the binuclear active site quenches the tryptophan emission of the oxy-β-HpH. The removal of this system increases the fluorescence quantum yield and causes structural ...
of the boiling tube was then poured into a flask containing 20 mL of 5 %potassiumiodide solution, the tube was washed out twice with 25 mL of water and then titration with 0.002 M sodium thiosulphate solution was done using starch as an indicator. A blank test was carried out at...
