RugositéIndex. décimale : 667.9 Revêtements et enduits Résumé : In this study, we have investigated the methods for development of a double layer ZnO-based coating through incorporation of a thin layer of low surface energy coating without any additional treatments. A binary micro-nano structure was observed on the surface topography analysis from the field emission scanning electron microscopy (FESEM) contact angle measurements on the surface, for oil droplet was 85° which is indicative of stable oleophobic properties which might contribute to the low surface energy on the coating and also relate to the surface roughness according to the randomly distributed ZnO particles. We believe that such multifunctional coatings can potentially impose many promising properties for engineering superolephobic surfaces.

TalcIndex. décimale : 667.9 Revêtements et enduits Résumé : Paper manufacturers are constantly looking for new methods to improve coated paper properties. Pigments are encountered in paper coatings to add new functions. For example, titanium dioxide (TiO2 ) and talc are considered among the best-known pigments used in paper coating and manufacturing due to their whiteness and other beneficial properties. Nevertheless, talc has a weak dispersion during which its particles agglomerate, and this disadvantage needs to be overcome before its application which means higher cost. Therefore, in this work, a core–shell technique is used to modify the talc surface and enhance its dispersion in order to promote its use in improving the properties of the paper. Core–shell pigments are composed of a thin shell of (nano- and micronized) titanium dioxide precipitated on talc particles. These prepared talc/TiO2 core–shell pigments were characterized using various techniques such as XRF, SEM, and TEM, and then they were incorporated in paper coatings to evaluate their effect on the different properties of the coated papers. The results showed that nano-talc/TiO2 with the obtained unique chemical and morphological structure has improved the physical, mechanical, and optical properties of the coated papers besides improving their antimicrobial activity, especially when compared to papers coated with micronized talc/TiO2. Note de contenu : - EXPERIMENTAL : Materials - Preparation of nano-TiO2/talc core–shell pigments - Preparation of micronized TiO2/talc core–shell pigments - Methods of instrumental analysis - Application of the prepared TiO2/talc core–shell pigments in paper coating - Antibacterial activity test for the prepared pigment

Ingrédients cosmétiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : After almost three years of an ongoing pandemic, climate change sent its regards this summer to remind humankind of what the future will look like. With political uncertainties arising worldwide, a sustainable oil source becomes increasingly important in both terms: ecological and economical. Yeast oil, triacylglycerides produced by oleaginous yeasts, is a promising alternative or even replacement to plant oils like cocoa butter, palm oil and similar. It has a small ecological footprint, can be produced locally in a reliable manner and has unique characteristics making it functional in multiple applications. The following article aims to give an exciting glimpse into a trending topic and COLIPI, a startup located in Hamburg dedicated to leading the fat revolution. Note de contenu : - COLIPI's process

PyrolyseLa pyrolyse est la décomposition ou thermolyse d'un composé organique par la chaleur pour obtenir d'autres produits (gaz et matière) qu'il ne contenait pas. L'opération est réalisée en l'absence d'oxygène ou en atmosphère pauvre en oxygène pour éviter l'oxydation et la combustion (L’opération ne produit donc pas de flamme). Il s'agit du premier stade de transformation thermique après la déshydratation.
Elle permet généralement d'obtenir un solide carboné, une huile et un gaz. Elle débute à un niveau de température relativement bas (à partir de 200 °C) et se poursuit jusqu'à 1 000 °C environ. Selon la température, la proportion des trois composés résultants est différente.Index. décimale : 668.4 Plastiques, vinyles Résumé : Synergistic flame-retardant effect of aluminum diethyl phosphinate (AlPi) in intumescent flame retardant polypropylene (PP/IFR) system and the flame-retardant mechanism were investigated. The flame retardancy of PP/IFR/AlPi (the mass ratio of IFR to AlPi is 2 : 1) was the best, which was proved by the results of the limiting oxygen index (LOI) test, UL-94 test, and cone calorimeter test ( CCT) test. Here, the LOI value of the sample was as high as 34% and passed the V–0 rating in UL–94 test. The peak heat release rate (PHRR) decreased by 92.57%, the total heat release (THR) reduced by 90.52%. Thermogravimetric (TGA) data showed that the introduction of AlPi improved thermal stability and changed the thermal degradation behavior of PP/IFR composites. Interestingly, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDXS) and laser Raman spectroscopy (LRS) proved that PP/IFR/AlPi had formed more residual carbon, but the flame retardancy was worse than PP/IFR/AlPi. This is because when the mass ratio of IFR to AlPi is 2 : 1, the synergy between IFR and AlPi was significant, gas-phase flame retardant and condensed-phase flame retardant reached a balance and obtained the best flame retardant effect.

These dyes showed a molar extinction coefficient in the range of 20 000–30 000 l/mol/cm. These compounds were characterised by strong solid-state fluorescence under long ultraviolet light (365 nm). Absorption and fluorescence spectra revealed that electron coupling originating from broad π-electron delocalisation and the keto–enol form is responsible for the large Stokes shift. These dyes were readily soluble in common solvents such as dichloromethane, chloroform, dimethyl formamide, tetrahydrofuran and dimethyl sulphoxide and were characterised by means of elemental analysis, proton nuclear magnetic resonance and mass spectrometry. Thermogravimetric analysis of solid-state fluorescent dyes show thermal stability up to 270 °C and can therefore be used for polymer application. The coloristic properties of these dyes were evaluated on polyester by the disperse dyeing method.
