A strong base is abasethat is completely dissociated in anaqueous solution. These compounds ionize in water to yield one or more hydroxide ion (OH-) per molecule of base. In contrast,a weak baseonly partially dissociates into its ions in water. Ammonia is a good example of a weak base. ...
1. The SUP gene was excised from the pCloneJET vector by restriction digestion and run on a 1% agarose gel in TAE buffer (per 1 L, 108 g Tris base, 57.1 mL glacial acetic acid, 0.05 m EDTA, pH 8.0). The band containing the SUP gene was excised from the gel and ...

In this study, we investigate the properties of hydrophilic polymer matrices comprising HPC and four different NADES (NADES gels): choline chloride: urea 1:2 (ChCl-U), choline chloride: citric acid 1:1 (ChCl-CA), choline chloride: lactic acid 1:1 (ChCl-LA), choline chloride: glycerol...
For trace elements (Sc, Ti, V, Co, Cu, Zn, Ge, Rb, Sr, Y, Zr, Nb, Cs, Ba, Hf, Ta, Pb, Th and U) analysis, the samples were first digested by an HNO3 + HF acid mixture in high-pressure bombs, and then measured using a Perkin-Elmer Elan 6000 ICP-MS with detection ...
