Single-molecule magnet behaviour in polynuclear assembly of trivalent cerium ions with polyoxomolybdates.

Dalton transactions (Cambridge, England : 2003)

Khélifa AB, Belkhiria MS, Huang G, Freslon S, Guillou O, Bernot K.
PMID: 26314612
Dalton Trans. 2015 Oct 07;44(37):16458-64. doi: 10.1039/c5dt02377g.

An isopolyoxomolybdate-based POM is coordinated to trivalent cerium ions to afford a hybrid complex namely, [Ce(dmso)8][Ce(η2-NO3)2(dmso)4(α-Mo8O26)0.5][Mo6O19]. The original electrostatic environment created around the Ce(III) by its coordination to the isopolyoxomolybdate core induces complex single-molecule magnet behavior.

Predator identity and trait-mediated indirect effects in a littoral food web.

Oecologia

Bernot RJ, Turner AM.
PMID: 28547061
Oecologia. 2001 Sep;129(1):139-146. doi: 10.1007/s004420100705. Epub 2001 Sep 01.

Perturbations to the density of a species can be propagated to distant members of a food web via shifts in the density or the traits (i.e. behavior) of intermediary species. Predators with differing foraging modes may have different effects...

Picosecond pulse radiolysis of tetrahydrofuran (THF) solutions containing earth alkaline metal salt, M(II)(ClO4)2, at different concentrations are performed using two different supercontinua as probe pulse, one covering the visible and another the near-infrared (NIR) down to the visible. Two...

Detection of mental imagery and attempted movements in patients with disorders of consciousness using EEG.

Frontiers in human neuroscience

Horki P, Bauernfeind G, Klobassa DS, Pokorny C, Pichler G, Schippinger W, Müller-Putz GR.

Front Hum Neurosci. 2014 Dec 12;8:1009. doi: 10.3389/fnhum.2014.01009. eCollection 2014.

Further development of an EEG based communication device for patients with disorders of consciousness (DoC) could benefit from addressing the following gaps in knowledge-first, an evaluation of different types of motor imagery; second, an evaluation of passive feet movement...

Unraveling the crystal structure of lanthanide-murexide complexes: use of an ancient complexometry indicator as a near-infrared-emitting single-ion magnet.

Chemistry (Weinheim an der Bergstrasse, Germany)

Yi X, Bernot K, Le Corre V, Calvez G, Pointillart F, Cador O, Le Guennic B, Jung J, Maury O, Placide V, Guyot Y, Roisnel T, Daiguebonne C, Guillou O.

Chemistry. 2014 Feb 03;20(6):1569-76. doi: 10.1002/chem.201303833. Epub 2014 Jan 08.

Herein, we provide some structural evidence of the complexation color-change of murexide solutions in presence of lanthanide, which has been used for decades in complexometric studies. For Ln = Sm to Lu and Y, the compounds crystallize as monomeric...

Nanotechnology

Savelli G, Stein SS, Bernard-Granger G, Faucherand P, Montès L, Dilhaire S, Pernot G.
PMID: 26086207
Nanotechnology. 2015 Jul 10;26(27):275605. doi: 10.1088/0957-4484/26/27/275605. Epub 2015 Jun 18.

Ti-based silicide quantum dot superlattices (QDSLs) are grown by reduced-pressure chemical vapor deposition. They are made of titanium-based silicide nanodots scattered in an n-doped SiGe matrix. This is the first time that such nanostructured materials have been grown in...

Analysis of the electrostatics in Dy(III) single-molecule magnets: the case study of Dy(Murex)3.

Dalton transactions (Cambridge, England : 2003)

Jung J, Yi X, Huang G, Calvez G, Daiguebonne C, Guillou O, Cador O, Caneschi A, Roisnel T, Le Guennic B, Bernot K.

Dalton Trans. 2015 Nov 07;44(41):18270-5. doi: 10.1039/c5dt03345d. Epub 2015 Oct 05.

A Dy(III)-based single-molecule magnet is reported. Ab initio calculations highlight that molecular symmetry plays a predominant role over site symmetry in determining the shape and orientation of Dy(III) magnetic anisotropy. Moreover the dipolar component of the electrostatic potential created...

In situ biasing and off-axis electron holography of a ZnO nanowire.

Nanotechnology. 2018 Jan 12;29(2):025710. doi: 10.1088/1361-6528/aa923c.

Quantitative characterization of electrically active dopants and surface charges in nano-objects is challenging, since most characterization techniques using electrons [1-3], ions [4] or field ionization effects [5-7] study the chemical presence of dopants, which are not necessarily electrically active....

Pulse radiolysis was used to study the mechanism of HO(•)-induced polymerization of poly(3,4-ethylenedioxythiophene), PEDOT, in aqueous solution. A step-by-step mechanism has been found which involves a recurrent oxidation process by HO(•) hydroxyl radicals produced by water radiolysis. Furthermore, the...

Direct imaging of p-n junction in core-shell GaN wires.

Nano letters

Tchoulfian P, Donatini F, Levy F, Dussaigne A, Ferret P, Pernot J.
PMID: 24837761
Nano Lett. 2014 Jun 11;14(6):3491-8. doi: 10.1021/nl5010493. Epub 2014 May 29.

While core-shell wire-based devices offer a promising path toward improved optoelectronic applications, their development is hampered by the present uncertainty about essential semiconductor properties along the three-dimensional (3D) buried p-n junction. Thanks to a cross-sectional approach, scanning electron beam...
