Electrochemical assessment of water|ionic liquid biphasic systems towards cesium extraction from nuclear waste

A room temperature ionic liquid (IL) composed of a quaternary alkylphosphonium (trihexyltetradecylphosphonium, P66614(+)) and tetrakis(pentafluorophenyl) borate anion (TB) was employed within a water| P66614TB (w|P66614TB or w|IL) biphasic system to evalua ...

Structure and Properties of the Precursor/Successor Complex and Transition State of the CrCl2+/Cr2+ Electron Self-Exchange Reaction via the Inner-Sphere Pathway

François Rotzinger

The electron self-exchange reaction CrCl(OH2)5(2+) + Cr(OH2)6(2+) -> Cr(OH2)(6)(2+) + CrCl(OH2)(5)(2+), proceeding via the inner-sphere pathway, was investigated with quantum-chemical methods. Geometry and vibrational frequencies of the precursor/successor ...

A structure-guided fragment-based approach for the discovery of allosteric inhibitors targeting the lipophilic binding site of transcription factor EthR

Stewart Cole, Benoit Lechartier

A structure-guided fragment-based approach was used to target the lipophilic allosteric binding site of Mycobacterium tuberculosis EthR. This elongated channel has many hydrophobic residues lining the binding site, with few opportunities for hydrogen bondi ...

Exploring Weak Ligand-Protein Interactions by Long-Lived NMR States: Improved Contrast in Fragment-Based Drug Screening

Geoffrey Bodenhausen, Daniele Mammoli, Roberto Buratto

Ligands that have an affinity for protein targets can be screened very effectively by exploiting favorable properties of long-lived states (LLS) in NMR spectroscopy. In this work, we describe the use of LLS for competitive binding experiments to measure ac ...

Science + Space + Society : Urbanity and the Risk of Methodological Communalism in Social Sciences of Space

Jacques Lévy

During the last decades, geography has lost its epistemological exceptionality, but is this enough? Social sciences are commonly threatened by methodological nationalism and, more generally, by methodological communalism, that is the corruption of a scient ...

Lanthanide Complexes Based on beta-Diketonates and a Tetradentate Chromophore Highly Luminescent as Powders and in Polymers

Marinella Mazzanti

A new type of octacoordinated ternary β-diketonates complexes of terbium and europium has been prepared using the anionic tetradentate terpyridine-carboxylate ligand (L) as a sensitizer of lanthanide luminescence in combination with two β-diketonates ligan ...

Tenascin C Promiscuously Binds Growth Factors via Its Fifth Fibronectin Type III-Like Domain

Jeffrey Alan Hubbell, Federico Tortelli, Jeffrey James Rice

Tenascin C (TNC) is an extracellular matrix protein that is upregulated during development as well as tissue remodeling. TNC is comprised of multiple independent folding domains, including 15 fibronectin type III-like (TNCIII) domains. The fifth TNCIII dom ...

Selective Delivery of an Anticancer Drug with Aptamer-functionalized Liposomes to Breast Cancer Cells in vitro and in vivo

Li Tang, Yi Lu

Selective targeting of cancer cells is a critical step in cancer diagnosis and therapy. To address this need, DNA aptamers have attracted significant attention as possible targeting ligands. However, while their use in targeting cancer cells in vitro has b ...

Enhancement of Cytotoxicity by Combining Pyrenyl-Dendrimers and Arene Ruthenium Metallacages

Paul Joseph Dyson, Olivier Pierre Zava

Three generations of pyrenyl bis-MPA dendrimers with two different end-groups, acetonide (pyrG) or alcohol (pyr(Gn center dot OH)) (n = 1-3), were synthesized, and the pyrenyl group of the dendritic molecules was encapsulated in the arene ruthenium metalla ...
