Collective hydrogen-bond dynamics dictates the electronic structure of aqueous I3-

The mol. and electronic structures of aq. I3- and I- ions have been investigated through ab initio mol. dynamics (MD) simulations and photoelectron (PE) spectroscopy of the iodine 4d core levels. Against the background of the theor. simulations, data from ...

Chalcopyrite thin-film solar cells by industry-compatible ink-based process

Cyril Cayron

We developed a new industry-compatible ink-based process to produce efficient chalcopyrite CuIn1-xGaxSe2 thin-film solar cells. Metallic In and Ga nanoparticles were produced by purely physical methods, using a low-cost and non-explosive solvent. The solve ...

Formation and Properties of Self-Assembly-Driven Fluorescent Nanoparticle Sensors

Paul Joseph Dyson, Zhaofu Fei

Fluorescent nanoparticles (FNPs) are obtained in water by self-assembly from a polymeric ionic liquid, fluorescent carboxylate moiety, and a surfactant through two main supramolecular interactions, that is, ionic bonds and hydrophobic/hydrophilic interacti ...

Development of Palladium Surface-Enriched Heteronuclear Au-Pd Nanoparticle Dehalogenation Catalysts in an Ionic Liquid

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Yuan Yuan, Xi Chen, Xiao Yuan

Heteronuclear Au–Pd nanoparticles were prepared and immobilized in the functionalized ionic liquid [C2OHmim][NTf2]. The structural and electronic properties of the nanoparticles were characterized by a range of techniques and the surface of the nanoparticl ...

Quantitative separation of monomeric U(IV) from UO2 in products of U(VI) reduction

Rizlan Bernier-Latmani, Benjamin Uster, Elena Suvorova Buffat, Harish Veeramani, Daniel Scott Alessi

The reduction of soluble hexavalent uranium to tetravalent uranium can be catalyzed by bacteria and minerals. The end-product of this reduction is often the mineral uraninite, which was long assumed to be the only product of U(VI) reduction. However, recen ...

Ion transfer across the water | trifluorotoluene interface

Hubert Girault, Astrid Johana Olaya Avendano, Peiyu Ge

This work introduces trifluorotoluene as an alternative organic solvent for studying charge transfer across liquid vertical bar liquid interfaces. In comparison with the most popular organic solvents in this field, 1,2-dichloroethane and nitrobenzene, trif ...

Non-aqueous solvents for DNP surface enhanced NMR spectroscopy

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli, David Benjamin Roger Antoine Gajan

A series of non-aqueous solvents combined with the exogenous biradical bTbK are developed for DNP NMR that yield enhancements comparable to the best available water based systems. 1,1,2,2-tetrachloroethane appears to be one of the most promising organic so ...

Backbone Assignment of Fully Protonated Solid Proteins by 1H Detection and Ultrafast Magic-Angle-Spinning NMR Spectroscopy

David Lyndon Emsley

Narrow 1H NMR linewidths can be obtained for fully protonated protein samples in the solid state by using ultrafast magic-angle spinning (60 kHz). Medium-size microcrystalline and noncrystalline proteins can be analyzed without any need for deuteration of ...

3D Phase-Field Simulation of Micropore Formation during Solidification: Morphological Analysis

Michel Rappaz, Alain Jacot, Hossein Meidani

A 3D multiphase-field (PhF) model has been developed in order to study the formation of a micropore constrained to grow in a solid network (i.e., pinching effect). The model accounts for the pressure difference due to capillarity between liquid and gas, th ...
