An efficient electrosynthesis of homoallylic alcohols from allylic bromides and aldehydes in aqueous ammonia is achieved in an undivided cell fitted with a pair of zinc electrodes.

We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system. This metagenome bin was discovered through shotgun DNA sequencing of samples from biologically active filters at the drinking water treatment plant in An...

Marshall’s1 urease method, in the modification proposed by Van Slyke and Cullen, is apparently the most accurate method available for the determination of urea. The method has, however, not yet attained the maximal degree of accuracy to be expected from volumetric processes in general. From the published figures of Van Slyke and Cullen, their modification appears to yield duplicates agreeing wi...

In a similar manner the non-existence of the compound LiNH, is established. In this case independent evidence is given which shows conclusively that in a system containing lithium and a small molecular per cent. of ammonia a saturated solution of the metal in ammonia is formed. This result is in agreement with the phase relationships existing in the system and demonstrates the inapplicability o...

Thermal energy was shown to be efficiently converted into electrical power in a thermally regenerative ammonia-based battery (TRAB) using copper-based redox couples [Cu(NH3)4 /Cu and Cu(II)/Cu]. Ammonia addition to the anolyte (2 M ammonia in a copper-nitrate electrolyte) of a single TRAB cell produced a maximum power density of 115 1 W m 2 (based on projected area of a single copper mesh elect...

This article re-examines two historic Supreme Court’s decisions—the 1964 Times v. Sullivan and the 1974 Gertz v. Welch—as they apply to the digital era. The Court’s decision in Sullivan established the federal legal guidelines for a victim to prove a libel case including actual malice. In Gertz v. Welch the Court established three categories of public figures who must prove actual malice in a l...

An apparatus is proposed primarily for comparison with other methods for determination of “blood ammonia,” and studies of involved factors. It employs the aeration-diffusion method of Van Slyke and Cullen, but in a closed system which avoids loss of ammonia and contamination with ammonia from the outside. Incomplete liberation of ammonia is avoided by the use of a moving thin film ever renewed ...

conclusions the ammonia degassing is a simple and suitable technology for ammonia removal at high concentration. undesirable removal efficiency (17%, 35.5% and 31%) can be occurred in suitable ph 11 in the presence of lower ammonia concentrations (50, 100 and 200 mg/l). results according to obtained results, the maximum removal efficiencies were determined 17%, 35.5%, 31%, 66%, and 85.5%, for 5...
