PMID: 24869675
ACS Nano. 2014 Jun 24;8(6):6449-57. doi: 10.1021/nn502029b. Epub 2014 Jun 02.

Spatial variability of electronic transport in BiFeO3-CoFe2O4 (BFO-CFO) self-assembled heterostructures is explored using spatially resolved first-order reversal curve (FORC) current voltage (IV) mapping. Multivariate statistical analysis of FORC-IV data classifies statistically significant behaviors and maps characteristic responses spatially. In...

The electrochemical reactivity of solid surfaces underpins functionality of a broad spectrum of materials and devices ranging from energy storage and conversion, to sensors and catalytic devices. The surface electrochemistry is, however, a complex process, controlled by the interplay...

Local coexistence of VO2 phases revealed by deep data analysis.

Scientific reports

PMID: 27384473
Sci Rep. 2016 Jul 07;6:29216. doi: 10.1038/srep29216.

We report a synergistic approach of micro-Raman spectroscopic mapping and deep data analysis to study the distribution of crystallographic phases and ferroelastic domains in a defected Al-doped VO2 microcrystal. Bayesian linear unmixing revealed an uneven distribution of the T...

Spatio-spectral structures in high-order harmonic beams generated with Terawatt 10-fs pulses.

Nature communications

Dubrouil A, Hort O, Catoire F, Descamps D, Petit S, Mével E, Strelkov VV, Constant E.
PMID: 25115933
Nat Commun. 2014 Aug 13;5:4637. doi: 10.1038/ncomms5637.

A large international effort is nowadays devoted to increase the energy of the extreme ultraviolet pulses by using high-peak power ultrashort fundamental pulses (Terawatt level). Using such fundamental pulses brings specific constraints that need to be addressed. Here we...

Defective interfaces in yttrium-doped barium zirconate films and consequences on proton conduction.

Nano letters

Yang N, Cantoni C, Foglietti V, Tebano A, Belianinov A, Strelcov E, Jesse S, Di Castro D, Di Bartolomeo E, Licoccia S, Kalinin SV, Balestrino G, Aruta C.
PMID: 25789878
Nano Lett. 2015 Apr 08;15(4):2343-9. doi: 10.1021/acs.nanolett.5b00698. Epub 2015 Mar 23.

Yttrium-doped barium zirconate (BZY) thin films recently showed surprising electric transport properties. Experimental investigations conducted mainly by electrochemical impedance spectroscopy suggested that a consistent part of this BZY conductivity is of protonic nature. These results have stimulated further investigations...

Comprehensive analysis of metabolites in Corynebacterium glutamicum by gas chromatography/mass spectrometry.

Biological chemistry

Strelkov S, von Elstermann M, Schomburg D.
PMID: 15493881
Biol Chem. 2004 Sep;385(9):853-61. doi: 10.1515/BC.2004.111.

An analytical method based on gas chromatography/mass spectrometry was developed for metabolome investigation of Corynebacterium glutamicum. For the first time a fast method for metabolic screening that can be automated is described for this organism. More than 1000 compounds...

Temporal gene expression profiling of the wheat leaf rust pathosystem using cDNA microarray reveals differences in compatible and incompatible defence pathways.

International journal of plant genomics

The effect of Joule self-heating of the semiconducting metal oxide nanowire (here (and below unless specified), due to the generality of the effect, we use the term 'nanowire' without specification as to whether the nanobelt or other class of...

Monitoring atomic cluster expansion by high-harmonic generation.

Physical review letters

High-harmonic generation is shown to be capable of providing time-resolved information about the particle density of a complex system. As an example, we study numerically high-harmonic generation from expanding xenon clusters in a pump-probe laser scheme, where the pump...
