, 2016, pp.14p. We describe the prototyping of a battery-powered, RFID-enabled carbon nanotube strain sensor for concrete strain and crack monitoring. A series of 10 prototypes has been embedded in a real structure. After a year it is still providing valuable information on the state of the structure. The final volume of the embedded module is 43cm3, the lowest volume reported to date in the field of embedded monitoring of concrete.
Claquage Electrique et Optique d'Allotropes du Carbone : Mécanismes et Applications pour le Stockage de Données
- Loisel Loïc
, 2016. Aujourd’hui, les applications de stockage de données utilisent principalement deux types de matériaux : les chalcogénures pour le stockage optique (e.g. Blu-Ray) et le silicium pour le stockage électronique (e.g. mémoires Flash). Malgré le fait qu’ils se soient avérés les plus efficaces pour des applications répandues, ces matériaux ont des limitations. Récemment, avec la montée en puissance du graphene, les allotropes du carbone ont été étudiés à la fois pour leurs propriétés intrinsèques et pour des applications ; ils ont des propriétés électroniques, thermiques et mécaniques très intéressantes qui peuvent rendre ces matériaux plus efficaces que les chalcogénures ou le silicium pour certaines applications. Dans cette thèse, nous étudions la faisabilité et le potentiel du carbone comme matériau pour le stockage de données.Nous nous concentrons d’abord sur le développement de stockage optique. Nous découvrons que les lasers continus et pulsés peuvent être utilisés pour induire des changements de phase réversibles dans des couches minces de carbone, confirmant la possibilité d’utiliser le carbone comme un matériau pour le stockage optique. De plus, nous découvrons plusieurs nouveaux phénomènes, que nous expliquons en utilisant des techniques de caractérisation avancées et de la modélisation par ordinateur de la propagation thermique dans le carbone.Ensuite, nous nous concentrons sur le stockage de données électronique en développant des mémoires à base de graphene qui peuvent être dans deux états de résistance bien séparés pour un grand nombre de cycles. Pour évaluer le potentiel de cette technologie, on caractérise le mécanisme de changement de résistance et on développe un modèle électromécanique qui permet de prédire les meilleures performances atteignables : ces mémoires ont le potentiel de commuter bien plus rapidement que les mémoires Flash tout en étant non-volatiles.

Journal of the American Chemical Society, American Chemical Society, 2016, 138, pp.3990-3993. This work describes the first thermally activated delayed fluorescence material enabling circularly polarized light emission through chiral perturbation. These new molecular architectures obtained through a scalable one-pot sequential synthetic procedure at room temperature (83% yield) display high quantum yield (up to 74%) and circularly polarized luminescence with an absolute luminescence dissymmetry factor, |$g_{lum}$|, of 1.3 × 10$^{−3}$. These chiral molecules have been used as an emissive dopant in an organic light emitting diode exhibiting external quantum efficiency as high as 9.1%. (10.1021/jacs.6b00850)

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, IEEE, 2016, 9 (16), pp.3249 - 3258. This paper investigates a new polarimetric device that produces reduced scale measurements for bistatic radar. The optical scale device is proposed to overcome the lack of real bistatic and full polarimetric radar acquisitions for forest of trunks. It is based on the scale invariant rule that is deduced from the Maxwell equations. From this principle, the electromagnetic (EM) response is kept at the reduced scale if the illumination wavelength is scaled and if the permittivity remains the same. This last condition needs the use of a carefully chosen material at optical scale. Nanoscale scenes are composed of carbon nanotubes (CNTs). They present several advantages: their arrangement is similar to the structure of a forest of trunks, their shape, and density can be controlled, it is possible to create very large scenes composed of thousands of elements, and finally their permittivity at optical wavelength is about the same order of magnitude than the permittivity of the tree trunks at radar wavelength. They are measured under the view of a microscope objective with a 633-nm wavelength laser playing the role of the EM source. The device images at once the forest polarimetric response, for a given transmitter location, and for the entire set of angular positions of reception. Two samples of forests with different densities are measured. They are analyzed using the Cloude and Pottier decomposition and the Lu and Chipman decomposition. The produced results are unprecedented on forest-like environment and it would be very helpful for the radar community. (10.1109/JSTARS.2016.2532802)

Journal of Materials Chemistry A, Royal Society of Chemistry, 2016, 4, pp.4831-4839. Photoelectrodes based on solution-processed organic semiconductors are emerging as low-cost alternatives to crystalline semiconductors and platinum. In this work, the performance and stability of P3HT:PCBM\MoS 3-based photocathodes are considerably improved by changing the hole-extracting layer (HEL). Oxides such as reduced graphene oxide, nickel oxide or molybdenum oxide are deposited via solution processes. With MoO x , a photocurrent density of 2 mA cm À2 during 1 h is obtained with the processing temperature lower than 150 C – thus compatible with flexible substrates. Furthermore, we show that the performances are directly correlated with the work function of the HEL material, and the comparison with solid-state solar cells shows that efficient HELs are not the same for the two types of devices.

Nanoscale Research Letters, SpringerOpen, 2016, 11 (1), pp.55. Both surface photovoltage and photocurrent enable to assess the effect of visible light illumination on the electrical behavior of a solar cell. We report on photovoltage and photocurrent measurements with nanometer scale resolution performed on the cross section of an epitaxial crystalline silicon solar cell, using respectively Kelvin probe force microscopy and conducting probe atomic force microscopy. Even though two different setups are used, the scans were performed on locations within 100-μm distance in order to compare data from the same area and provide a consistent interpretation. In both measurements, modifications under illumination are observed in accordance with the theory of PIN junctions. Moreover, an unintentional doping during the deposition of the epitaxial silicon intrinsic layer in the solar cell is suggested from the comparison between photovoltage and photocurrent measurements.

Diamond and Related Materials, Elsevier, 2016, 68, pp.23-27. Porous diamond foam exhibiting a three-dimensional structure was synthesized by applying prolonged Bias Enhanced Nucleation on iridium buffer layers. The Raman spectrum of this material recorded at 325 nm looks very close to the signature obtained for detonation nanodiamonds. HRTEM investigations well confirm the presence of diamond crystals with nanometric size between 2 and 6 nm. All these diamond nanocrystals form a three-dimensional structure very different from ultrananocrystalline diamond (UNCD) generally embedded in a graphitic matrix. According to its high specific surface area, such a 3D material may have promising applications for sensors. (10.1016/j.diamond.2016.04.009)

Soft Matter, Royal Society of Chemistry, 2016, 12 (3), pp.678-688. Combining optical microscopy, synchrotron X-ray diffraction and ellipsometry, we studied the internal structure of linear defect domains (oily streaks) in films of smectic liquid crystal 8CB with thickness 100-300 nm confined between air and a rubbed PVA polymer substrate which impose hybrid anchoring conditions (normal and unidirectional planar, respectively). We show how the presence or absence of dislocations control the structure of highly deformed thin smectic films. Each domain contains smectic layers curved in the shape of flattened hemicylinders to satisfy both anchoring conditions, together with grain boundaries whose size and shape are controlled by the presence of dislocation lines. A flat grain boundary normal to the interface connects neighboring hemicylinders, while a rotating grain boundary (RGB) is located near the axis of curvature of the cylinders. The RGB shape appears such that dislocation lines are concentrated at its summit close to the air interface. The smectic layers reach the polymer substrate via a transition region where the smectic layer orientation satisfies the planar anchoring condition over the entire polymer substrate and whose thickness does not depend on the one of the film. The strength of the planar anchoring appears to be high, larger than 10 −2 J/m 2 , compensating for the high energy cost of creating an additional 2D defect between an horizontal smectic layer and perpendicular ones. This 2D defect may be melted, in order to avoid the creation of a transition region structure composed of a large number of dislocations. As a result, linear defect domains can be considered as arrays of oriented defects, straight dislocations of various Burger vectors, whose location is now known and 2D nematic defects. The possibility of easy variation between the present structure with a moderate amount of dislocations and a structure with a large number of dislocations is also demonstrated. (10.1039/C5SM02241J)

Journal of Materials Chemistry C, Royal Society of Chemistry, 2016, 4 (8), pp.1692-1703. We report herein the synthesis, and structural, electrochem. and photophys. properties of new dihydroindeno[2,1-b]fluorene-based semi-conductors, i.e. dispiro[thioxanthene-9,5'-indeno[2,1-b]fluorene-7',9''-thioxanthene] 2 and dispiro-[dioxothioxanthene-9,5'-indeno[2,1-b]fluorene-7',9''-thioxanthene] 3. These properties will be compared to those of the pure hydrocarbon deriv. dispiro[fluorene-9,5'-indeno[2,1-b]fluorene-7',9''-fluorene] 1 previously described. The incorporation of the sulfur atom within the bridged units allows tuning the HOMO and LUMO energy levels, nevertheless retaining the high ET of the dihydroindeno[2,1-b]fluorenyl core ([2,1-b]IF), the key feature of further device applications. This control of the properties has allowed incorporating 3 as the host material in blue and green phosphorescent OLEDs (PhOLEDs) with an EQE of 12.8% (at 1 mA cm-2 with the corresponding CE and PE of 48.6 cd A-1 and 29.5 lm W-1) for the green device and an EQE of 4.8% (at 1 mA cm-2 with the corresponding CE and PE of 14.8 cd A-1 and 8.2 lm W-1) for the sky-blue device. To the best of our knowledge, this work is the second example of incorporation of a dihydroindeno[2,1-b]fluorene based semi-conductor in a blue PhOLED and highlights the potential of this fragment in org. electronics.

Oxidation-Based Continuous Laser Writing in Vertical Nano-Crystalline Graphite Thin Films

Scientific Reports, Nature Publishing Group, 2016, pp.9p. Nano and femtosecond laser writing are becoming very popular techniques for patterning carbon-based materials, as they are single-step processes enabling the drawing of complex shapes without photoresist. However, pulsed laser writing requires costly laser sources and is known to cause damages to the surrounding material. By comparison, continuous-wave lasers are cheap, stable and provide energy at a more moderate rate. Here, we show that a continuous-wave laser may be used to pattern vertical nano-crystalline graphite thin films with very few macroscale defects. Moreover, a spatially resolved study of the impact of the annealing to the crystalline structure and to the oxygen ingress in the film is provided: amorphization, matter removal and high oxygen content at the center of the beam; sp2 clustering and low oxygen content at its periphery. These data strongly suggest that amorphization and matter removal are controlled by carbon oxidation. The simultaneous occurrence of oxidation and amorphization results in a unique evolution of the Raman spectra as a function of annealing time, with a decrease of the I(D)/I(G) values but an upshift of the G peak frequency.
