TL;DR: Aqueous solution studies regarding the identification and characterization of complexes formed by the VIVO ion and 11 3-hydroxy-4-pyridinone derivatives have been performed using EPR and UV/vis spectroscopic techniques, and relationships between the pKa of the -OH group in position 3 of the ring are provided.

TL;DR: In this paper, organic-inorganic hybrid precursors were used to obtain planar waveguides with low losses in the infrared (from 0.6-1.1 dB cm−1) and a number of propagating modes in the visible (losses from 0.4 −1.5 dB cm −1).

TL;DR: A fluorescent iron chelator, shown to be effective in inhibiting the growth of Mycobacterium avium in macrophages, is reported, together with the synthesis and characterization of two unsuccessful analogues selected to facilitate identification of the molecular properties responsible for the antimicrobial activity.

TL;DR: In this article, a systematic investigation of erbium diffusion in LiNbO3 is presented, where depth concentration profiles are obtained by secondary ion mass spectrometry (SIMS).

TL;DR: Results from an investigation in an in vivo model of STZ-induced diabetic rats demonstrate that compound bis(1,2-dimethyl-3-hydroxy-4(1H)-pyridinonate)zinc(II), Zn(dmpp)(2), significantly lowers the blood glucose levels of individuals, thus showing evidence of glucose lowering activity.
