Using a simple method of mass production of green carbon nanotags (G-tags) from harmful cyanobacteria, we developed an advanced and efficient imaging platform for the purpose of anticancer therapy. Approximately 100 grams of G-tags per 100 kilograms of harmful cyanobacteria were prepared using our eco-friendly approac…
Abstract A solid‐state ion‐exchange method was developed to synthesize Cu‐SSZ‐13 catalysts with excellent performance in the selective catalytic reduction of NOx with NH3 (NH3‐SCR) and with durable hydrothermal stability. Experiments provide evidence that isolated Cu ions were successfully exchanged into the pores, wh…
Graphene, a one-atom thick layer of graphite with a two-dimensional sp2-hybridized carbon network, has recently attracted tremendous research interest due to its peculiar properties such as good mechanical strength, high thermal conductivity, superior transparency, large specific surface area and exceptional charge tr…
Manganese (Mn) substituted cobalt ferrites (CoFe2-xMnxO4, referred to CFMO) have been synthesized by the solid state reaction method and their dielectric properties and ac conductivity have been evaluated as a function of applied frequency and temperature. X-ray diffraction measurements indicate that CFMO crystallize…
We report on the near-field coupling of individual gold nanoantennas arranged in tip-to-tip dimer configuration, leading to strong electromagnetic field enhancements in the infrared, which is of great interest for sensing applications such as surface-enhanced infrared spectroscopy. We quantitatively evaluated the enha…
The solid-state photodimerization of 9-methylanthracene is used as a model system to investigate how crystal morphology and reaction dynamics affect photomechanical deformations of single microcrystals. By varying the crystallization conditions, two different crystal shapes, microneedles and microribbons, are grown on…
A hexathiobenzene molecule carrying six terpyridine (tpy) units at the periphery has been designed to couple the aggregation induced phosphorescence, displayed by the core in the solid state, to the metal binding properties of the tpy units. Upon Mg(2+) complexation in THF solution, phosphorescence of the hexathiobenz…
Hydrophilic graphene oxide (GO) nanosheets can be easily coated onto stainless steel meshes. Compared to neat meshes, GO coated meshes become more hydrophilic in air and superoleophobic under water. Taking advantage of this completely opposite wettability, GO coated meshes were used for gravity-driven oil-water separa…
Two-dimensional materials are one of the most active areas of nanomaterials research. Here we report the structural stability, electronic and vibrational properties of different monolayer configurations of the group IV elemental materials silicene and germanene. The structure of the stable configuration is calculated…
The synthesis of polymer therapeutics capable of controlled loading and synchronized release of multiple therapeutic agents remains a formidable challenge in drug delivery and synthetic polymer chemistry. Herein, we report the synthesis of polymer nanoparticles (NPs) that carry precise molar ratios of doxorubicin, cam…
Layered molybdenum disulfide (MoS2) has been studied for decades for its diversity of structure and properties, where the structural dynamic evolution during lithium intercalation is an important but still indistinct, controversial topic. Here the electrochemical dynamic process of MoS2 nanosheets upon lithium interca…

Le reformage catalytique du methane en hydrogene, vecteur d'energie pour les piles a combustibles de type Solid Oxide Fuel Cell (SOFC), a ete etudie sur des materiaux d'anode a base de metaux supportes (NiO/CeO2, NiO-Y2O3-ZrO2) et egalement sur des catalyseurs de structure definie (La0,8Sr0,2TiO3+δ). La premiere famil…
Beaucoup d’applications en ingenierie demandent l’utilisation de materiaux intelligents qui peuvent se deformer en reponse a un stimulus exterieur. C’est dans ce contexte, que s’est pose ce projet de recherche. Beneficiant d’un environnement pluridisciplinaire, grâce a l’association de deux axes de l'Institut Pascal :…

Ce travail s'inscrit dans le cadre d'une thèse Cifre, en partenariat avec la société VIESSMANN Faulquemont SAS, dont l'objectif est d'aboutir à une couche absorbante de nouvelle génération qui vise à réguler de manière passive et réversible la température d'un capteur solaire. Cette couche absorbante est à base de dio…
La supraconductivité s’établit par une organisation collective des électrons, décrite dans le cadre de la théorie BCS par une même fonction d’onde macroscopique. En présence de fort désordre, la situation est plus complexe : le désordre induit un renforcement des interactions coulombiennes et une localisation des élec…

Using fonts as a context, we will analyze symmetry of fi gures. Diff erent letters and numbers will be measured, and participants will describe items that possess vertical, horizontal, and rotational symmetry. Our discussion and activity will focus on the mathematics of fonts and the presence and absence of symmetry i…
