<p style="text-align: justify;">L'influence de plusieurs facteurs sur la consommation de l'oxygène et le potentiel d'oxydoréduction a été étudiée. Les facteurs choisis sont: les catalyseurs métalliques d'oxydation (fer et cuivre), les antioxydants (anhydride sulfureux et acide ascorbique), les principaux constituants du vin et les conditions de conservation.</p><p style="text-align: justify;">Le fer et le cuivre accélèrent les réactions d'oxydation dans les vins rouges.

Le matériau bois a depuis longtemps fait l'objet de traitements fongicides ou insecticides dont l'impact sur les sols après lessivage constitue un réel problème écologique. À ce jour, l'essentiel des études sur la dégradation de ces produits toxiques a été mené à partir des micro-organismes isolés en laboratoire. La présente étude a cherché à affiner les connaissances concernant ces microorganismes, en particulier les champignons lignivores dégradant les polluants in situ, pour lesquels peu de données sont en fait disponibles.

Abstract:
CuInSe 2 (CIS)-based powders were successfully prepared by a facile refluxing reaction route using metal halides and Se / S powder as raw starting materials. The phase and crystallographic structure, morphology, chemical composition of the products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS). It is found that single phase CIS powders with chalcopyrite structure can be prepared in a relatively short time using triethylenetetramine as the solvent; the most suitable reaction temperature and time are 200°C, 1–2 h, re

Abstract:
CuInSe2(CIS) is a promising material for thin film solar cell applications. In this work, CIS powders have been synthesized by solvothermal route at different reaction time. X-ray diffraction patterns and Raman spectra of the products reveal that the optimal reaction time is 36 h at 200 °C in order to obtain pure CIS phase. SEM images show an irregular morphology of synthesized CIS material. The formation pathway of CIS has also been studied. Cu-Se compounds are formed at the beginning of the reaction, which act as an important intermediate for the formation of CIS products. This result is not

Le succès exceptionnel de la sigillée, vaisselle de table en terre cuite de la période romaine, est en grande partie dû à la brillance et à la couleur rouge uniforme de sa couverte qui ont nécessité le développement de procédés techniques très performants. Dans cet article nous comparons les réalisations italiennes aux productions gauloises qui leur ont succédé, sous le regard de la science des matériaux. Nous montrons que l’étude des couvertes, en plus de permettre d’en comprendre la fabrication, a mis en évidence une évolution majeure de leurs propriétés physiques que l’on peut relier à une

Chalcopyrite CuInSe 2 (CIS) and CuInGaSe 2</sub(CIGS) nanoparticles were directly synthesized by a solvothemal route in an autoclave with alkylamine as a solvent. The rod-like CIS nanoparticles with widths of 5-10 nm and lengths of 10-30 nm were obtained at 180°C for 36 hour whereas spherical nanoparticles with diameter in the range of 10-80 nm were observed at 200- 250 °C for 36 hour. A morphology change from spherical to rod-like CIS nanoparticles was observed at 190 °C as reaction time increased from 36 to 60 hour.

Total of six hundred (600), one day-old chicks of Arbor acre breed were used for this experiment and fed red and black FM. Birds were allotted into ten (10) treatments of threereplicates,20 birds per replicate. Treatments 1 and 6 had no FM. Treatments 2, 3, 4 and 5 had red FM while treatments 7, 8, 9 and 10 had black FM.
