Polarized Cu K-edge XANES of square planar CuCl42− ion. Experimental and theoretical evidence for shake-down phenomena
TL;DR: In this article, the origin of the shoulder structure in the X-ray absorption spectra of a single crystal of (creatinium)2CuCl4 was found to be exclusively polarized in the direction normal to the molecular plane of the CuCl42− ion.

Fluorescence-based assay for reactive oxygen species: a protective role for creatinine.
TL;DR: Examination of the major components of human urine in this assay confirms that at physiological concentrations, urate protects against both types of oxygen radicals, and a novel finding is that creatinine protects efficiently by a chelation mechanism against radical damage in the ascorbate‐Cu2+ system at Creatinine, ascorBate, and Cu2+ concentrations comparable to those in normal urine.
