In this Progress Report, we first argue on the basis of theoretical considerations that in general organic semiconductors are intrinsically as good electron transporters as they are hole transporters. Then, in the light of selected experimental works, we discuss the origin of the features that prevent the observation of intrinsic electron transport, and the strategies that have been developed to promote ambipolar transport in field-effect transistors.Ambipolar Transport in Organic Conjugated MaterialsG00G00authorauthorauthorauthorCornil, J., Brédas, J.-L., Zaumseil, J., & Sirringhaus, H.

Pour exploiter au mieux les caractéristiques du gisement ét éviter de ralentir la production, les Carrières ont développé des collaborations avec le monde universitaire. Entre autres, la technique du géoradar a été utilisée en collaboration avec la Katholieke Universiteit van Leuven (KUL) pour localiser les zones altérées du gisement. L'extraction en carrière se fait essentiellement par découpage des bancs par des moyens mécaniques: le fil diamanté et la haveuse à chaîne. Pour bénéficier de l'expérience de la FPMs (Service de Génie Minier) dans le domaine de la destructibilité des roches, les Carrières développent une collaboration visant à améliorer les performances des haveuses. Les chaîne de ces machines sont équipées de pastilles de diamant synthétique. Les travaux de laboratoire permettent de simuler la coupe et de mesurer les énergies spécifiques associées à différentes conditions de fonctionnement et de déterminer les conditions optimales de fonctionnement.Exemple d'utilisation des techniques avancées pour améliorer l'exploitation du gisement aux carrières du ClypotC00C00G00authorauthorauthorauthorauthorauthorRoberti, R., Kirten, F., Grégoire, C., Tshibangu, K., Dagrain, F., & Kheffi, A.

In recent years, MIPs received an increasing attention in the field of natural products for their application in the drug discovery process. In this work, new synthesis strategies were developed to obtain imprinted cavities able to mimic the flexibility and mobility exhibited by receptor/enzyme binding pockets. For the study of working conditions, Quercetin (Qu) was chosen as a representative template considering it is one of the most active compounds in the flavonoids family, commonly found in medicinal and food herbal products. Bulk polymerization (BP), precipitation polymerization (PP) and suspension polymerization (SP) were investigated to obtain optimal chromatographic materials. The Qu MIPs (Fig. 1) were evaluated as sorbents for SPE and HPLC in order to confirm the presence of imprinted cavities and to evaluate their selectivity, respectively. By SPE, successful imprinting of the MIPs is confirmed when the retention appears distinctly superior on MIPs than on NIPs (Corresponding control polymers or non-imprinted polymers). The best SPE results were obtained for MIPs prepared by the SP method. Micrographs obtained by SEM reveal the large distribution of sizes and the irregular shape of particles prepared by BP. On the contrary, spherical beads with a well-controlled size distribution were obtained by SP indicating better perspectives for their use in chromatography. The MIPs were packed into HPLC columns in order to study their selectivity towards a set of analogues and non-analogues of quercetin. Thanks to the improved chromatographic efficiency afforded by SP, the developed MIPs are highly promising for the screening of lead compounds from complex systems such as natural products.MOLECULARLY IMPRINTED POLYMERS: TOWARDS RECEPTOR MIMICS FOR DRUG DISCOVERYC00D00G00authorauthorauthorauthorauthorPardo, A., Mespouille, L., Blankert, B., Dubois, P., & Duez, P.

When searching for food, the myzostome uses its protrusible introvert to fulfil two major functions: sensory perception and the capture of food particles. The digestive system is composed of four parts, viz. a pharynx, that is contained within the introvert, a stomach, a series of paired caeca and an intestine that lie in the myzostome's trunk. The pharynx is supplied with a thick muscle which, thanks to peristaltic movements, carries food particles from the mouth to the stomach. Both stomach and caecal cells are able to absorb dissolved nutriments and to store lipids, whereas intestinal cells are only capable of absorption. Due to the beating of their cilia, stomach cells also carry food particles into the caecal lumen, where they are subjected to endocytosis and intracellular digestion by caecal cells. Undigested food fragments eventually gather in a very large, apical vacuole, and the cell apices containing vacuoles are eliminated into the caecal lumen by an apocrinal process. Detached cell apices reach the stomach, where they are embedded in a matrix, together forming a spindle-shaped faecal mass that is expelled through the postero-ventral anus. The observed digestive process-entailing the regular elimination of the apical part of the caecal digestive cells-appears to be unique among the Spiralia.Functional morphology of the introvert and digestive system of Myzostoma cirriferum (Myzostomida)F00authorauthorauthorEeckhaut, I., Dochy, B., & Jangoux, M.
