Isothermal annealing of cold-rolled Al–Mn–Fe–Si alloy with different microchemistry states

Ke Huang

Microstructural evolution of a cold-rolled Al-Mn-Fe-Si alloy during annealing was studied. Except the as-cast variant, two other different homogenizations were considered, one gave a high density of fine dispersiods providing a considerable Zener drag infl ...

Chemo-mechanical behaviour of a low activity clay

Lyesse Laloui, Alessio Ferrari, Paul Joost Witteveen

Environmental geotechnics involves several engineering applications (such as the salinification of groundwater and the storage of nuclear wastes) for which a deep understanding of the chemo-mechanical behaviour of soils is a fundamental component. Despite ...

A dip coating process for large area silicon-doped high performance hematite photoanodes

Michael Graetzel, Artur Braun, Yelin Hu, Florent Alexandre Boudoire

A facile and low-cost dip-coating process for the deposition of silicon doped hematite films (Si:alpha-Fe2O3) for hydrogen production by solar water splitting in photo-electrochemical cells (PEC) is presented. The precursors include iron nitrate, oleic aci ...

Magnetic communication and reactivity of a stable homometallic cation-cation trimer of pentavalent uranyl

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The reaction of the UO2+ precursor [(UO 2Py5)(KI2Py2)]n, with the potassium salt of the tetradentate aza β-diketiminate ligand L (L = 2-(4-tolyl)-1,3-bis(quinolyl)malondiiminate) affords the ...

A calcium ion-selective electrode array for monitoring the activity of HepG2/C3As in a microchannel

Philippe Renaud, Robert Meissner

Variations in calcium ion (Ca2+) concentrations play a crucial role in cell-cell communication; periodic changes act as cellular signals. In this study, we developed a solid-state calcium ion-selective electrode (Ca2+ ISE) integrated in a microchannel to m ...

Barium Ions and Helium Nanodroplets: Solvation and Desolvation

Marcel Drabbels, Xiaohang Zhang

The solvation of Ba+ ions created by the photoionization of barium atoms located on the surface of helium nanodroplets has been investigated. The excitation spectra corresponding to the 6p 2P1/2

Studies of Ionic Current Rectification Using Polyethyleneimines Coated Glass Nanopipettes

Hubert Girault, Dmitry Momotenko, Yun Liu, Wenbo Zhao

The modification of glass nanopipettes with polyethyleneimines (PEIs) has been successfully achieved by a relatively simple method, and the smallest tip opening is around 3 nm. Thus, in a much wider range of glass pipettes with radii from several nanometer ...
