A locally calibrated, late glacial Be-10 production rate from a low-latitude, high-altitude site in the Peruvian Andes

Well-dated records of tropical glacier fluctuations are essential for developing hypotheses and testing proposed mechanisms for past climate changes. Since organic material for radiocarbon dating is typically scarce in low-latitude, high-altitude environme ...

Luminescence studies on photostimulable phosphor CsBr:Eu2+

Giovanni Dietler, Kanat Dukenbayev

Photostimulable phosphor CsBr:Eu2+ is prepared through a solid-state reaction. The effect of annealing atmosphere on photoluminescence and photostimulated luminescence was investigated. Optimum luminescence intensity was obtained when samples were prepared ...

Luminescent latex particles loaded with anionic lanthanide complexes: a versatile platform for multicolour optical coding

Marinella Mazzanti

Luminescent polymer latexes loaded with lanthanide complexes have been synthesized by miniemulsion polymerization. A self-assembled europium complex was embedded into poly(methyl methacrylate) nanoparticles without covalent linking and compared to a commer ...

The luminescence of NaxEu3+(2−x)/3MoO4 scheelites depends on the number of Eu-clusters occurring in their incommensurately modulated structure

Gervais Chapuis, Jean-Claude Bünzli, Alla Arakcheeva, Philip Pattison, Svetlana Eliseeva, Dmitry Logvinovich

Scheelite related compounds with general formula Mn(XO4)m are of interest owing to their optical properties, stability and relatively simple preparation. Eu3+-containing scheelites are considered as red emitting phosphors and the main factors affecting the ...

Antibacterial Ag-ZrN surfaces promoted by subnanometric ZrN-clusters deposited by reactive pulsed magnetron sputtering

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Oualid Baghriche

Ag-ZrN films were deposited on polyester by direct current pulsed magnetron sputtering (from now on DCMSP) in Ar + N-2 atmosphere. ZrN on the polyester surface interacts with Ag leading to Ag-ZrN films. These composite films were more active in Escherichia ...

Fabrication of polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics: The influence of initial pressure and sintering temperature on its morphology and photoluminescence activity

Barbora Bártová

Nanocrystalline (Y0.7Gd0.3)(2)O-3 powder, synthetised via polymer complex solution method, was compacted into 25 pellets applying high pressures (173-867 MPa) for 30 s that were subsequently sintered at different temperatures (800-1400 degrees C) for 18 h. ...

Catchment travel time distributions and water flow in soils

Andrea Rinaldo, Enrico Bertuzzo, Ludovico Nicotina, Gianluca Botter

Many details about the flow of water in soils in a hillslope are unknowable given current technologies. One way of learning about the bulk effects of water velocity distributions on hillslopes is through the use of tracers. However, this paper will demonst ...

Optical fiber-based setup for in vivo measurement of the delayed fluorescence lifetime of oxygen sensors

Hubert van den Bergh, Georges Wagnières, Filippo Piffaretti

A new optical-fiber-based spectrofluorometer for in vivo or in vitro detection of delayed fluorescence is presented and characterized. This compact setup is designed so that it can be readily adapted for future clinical use. Optical excitation is done with ...

Synchronising EDML and NorthGRIP ice cores using δ18O of atmospheric oxygen (δ18Oatm) and CH4 measurements over MIS5 (80-123 kyr)

Jérôme Chappellaz

An ice core air content record that was recovered from the refrozen-recrystallization ice formation zone in the Dasuopu Glacier was investigated in this work, which showed that the air content in ice performed significant fluctuations both in the seasonal ...
