TL;DR: In this article, the triazacycloalkanetriacetic acids screened for their ability to bind 111ln were evaluated and triazateclononanetrieacetate was found to be the most stable acid ligand with respect to acid dissociation.
Abstract: Of the four triazacycloalkanetriacetic acids screened for their ability to bind 111ln, triazacyclononanetriacetate bound indium most quickly and formed a complex whose dissociation as a function of pD was monitored by 13C NMR spectrometry using a labelled ligand (k296 1.8 × 10–1 dm3 mol–1 s–1) in the pD range 0 to –0.6. The corresponding gallium complex is even more stable with respect to acid dissociation and may be observed by 71Ga NMR spectrometry both in vitro(δGa+ 171 ppm) and in vivo. Crystal structures of the neutral gallium and of the protonated indium complexes are reported. The syntheses of a series of octadentate ligands are described and their relative efficiency to bind 90Y reported. Ligands based on tetraazacyclododecane bind 90Y most rapidly, and tetraazacyclododecanetetraacetate forms a strong complex with yttrium (log Ks 24.9, 298 K) which dissociates at low pH (< 2) as measured by HPLC and 13C NMR spectrometry.

TL;DR: The metal-based emission of a series of luminescent europium and terbium complexes incorporating an aromatic chromophore is rendered pH-dependent either through perturbation of the aryl singlet or triplet energy or by modulating the degree of quench of the lanthanide excited state.

TL;DR: The data indicate that the Ero1β protein is constitutively strongly expressed in the stomach and the pancreas, but in a cell-specific fashion, demonstrating that cell- specific differences exist in the regulation of oxidative protein folding in vivo.

TL;DR: The feasibility of the use of the screen-printed sensor to monitoring formaldehyde in ambient air and its performance compared to that of a biosensor made from the same platinised carbon and enzyme system, but without the lipophilic TTF-TCNQ and membrane, using a commercial 'Rank' cell are demonstrated.

TL;DR: OLEX2 seamlessly links all aspects of the structure solution, refinement and publication process and presents them in a single workflow-driven package, with the ultimate goal of producing an application which will be useful to both chemists and crystallographers.
Abstract: New software, OLEX2, has been developed for the determination, visualization and analysis of molecular crystal structures. The software has a portable mouse-driven workflow-oriented and fully comprehensive graphical user interface for structure solution, refinement and report generation, as well as novel tools for structure analysis. OLEX2 seamlessly links all aspects of the structure solution, refinement and publication process and presents them in a single workflow-driven package, with the ultimate goal of producing an application which will be useful to both chemists and crystallographers.
