A polyoxometalate-based lanthanide-organic framework was achieved using the {[Ho(4)(dpdo)(8)(H(2)O)(16)BW(12)O(40)] (H(2)O)(2)}(7+) nanocage as a secondary building block for the heterogeneous catalysis of phosphodiester cleavage in an aqueous solution.

This paper reports an apparent biological difference between two otherwise identical preparations of piperazine hexahydrate. It reports the cutaneous irritancy and allergenicity ofthis substance and records the effect ofenvironmental temperature on those properties, particularly the former. Finally, it reports severe, delayed asthma-like response to piperazine exposure. Interrogation of compani...

The 2D isostructural lanthanide-organic frameworks [Ln(4-SBA)(IP)OH] · 1.5H2O (Ln = Sm 1, Eu, 2 Gd3 and Tb 4 ; 4-SBA = 4-sulfobenzoate and IP = 1H-imidazo[4,5-f][1,10]-phenanthroline) display different luminescent behavior. White light emission was realized by introducing single dopant Eu(III) and codopants Eu(III)/Gd(III) or Eu(III)/Tb(III) into the Sm(III) framework for the first time.

To get complete information about the chemical composition and physicochemical principles underlying the formation of stone there is a need for more precise information. At present there is no single analytical procedure that provides an exact quantitative analysis of urinary calculi. In this present procedure it is assumed that only calcium oxalate monohydrate, hydroxyapatite, or magnesium amm...

Ciprofloxacin belongs to a family of quinolone antibacterial agents. The crystal structure of ciprofloxacin hydrochloride 1,34-hydrate was determined. Most of the bond lengths and angles of the ciprofloxacin cation are very similar to those of ciprofloxacin hexahydrate, which appears in the zwitterionic form. The exceptions are the carbon-oxygen bond distances in the carboxylic group, since in ...
