Over 100 μW of continuous-wave tunable ultraviolet radiation at 370 nm is generated by the sum-frequency mixing of radiation from two extended-cavity laser diodes having powers of 60 mW at 822 nm and 8 mW at 671 nm in a lithium iodate crystal. The crystal is placed in an external cavity that enhances the powers of two fundamental beams simultaneously by approximately 40. This light source is su...

The title salt, C(12)H(14)N(2) (2+)·2IO(3) (-), exhibits two crystallographically independent iodate anions, the I atoms of which are each in a trigonal-pyramidal environment. In the dication, the two pyridine rings adopt an anti conformation with respect to each other; the angle between these two rings is 3.84 (19)°. In the crystal structure, C-H⋯O hydrogen bonds between the cations and anions...

The mechanism of the action of chemical bread improvers has recently been the subject of wide discussion. J0rgensen (9, 10, 11 j 12,13),^ and Balls and Hale (2, 3) have advanced the theory that the improvement of baking quality caused by oxidizing agents, such as potassium brómate and potassium iodate, is due to the fact that they inactivate the proteinases of flour, thereby inhibiting the acti...

This manuscript addresses identification, analysis, formation and occurrence of key disinfection byproducts (DBPs) formed during chlorination and/or ozonation of both natural seawater (NSW), and synthetic high- and low-bromide saltwater (HBSW and LBSW, respectively). In this study, several groups of water disinfection byproducts were studied, including haloacetic acids (HAAs), halonitromethanes...
