• Recycling and recovery of local waste. • Saving of natural resources. • Reduction in material costs. • Reduction of greenhouse gas emissions. • Improvement of the quality of construction concrete. Disposing glass into open spaces and landfills is among the most serious environmental threats, as well as a source of potential health risks around the world. Therefore, in the construction sector, recovering discarded glass as a building material is gaining popularity since it reduces greenhouse gas-footprint and associated environmental problems. Our paper investigates experimental and numerical modeling of the uni-axial compression behavior at 28 days of concrete cylinders containing colored waste glass (WG) and confined by a polypropylene textile. In doing so, an experimental protocol was performed by partial substitution in concrete to reduce the cement and sand levels of 0%, 5%, 10% and 15%. The best-performing variant is confined with textile sourced from the salvage sector too though. In this section, we studied the experimental and numerical behavior taking into account the type of confinement such as total confinement (TCC), partial confinement concrete circular (PCCC), and partial confinement concrete helical (PCCH). The obtained results in terms of stress evolution are presented and discussed, indeed, they represent a promising revelation regarding the improvement in terms of rigidity. The confrontation of the experimental and numerical results shows a satisfactory agreement. [ABSTRACT FROM AUTHOR]

Superwettable surface for oil/water separation have received great interest due to their high separation selectivity. Nevertheless, the actual application of such material is greatly hampered by poor biodegradablity of the coating and poor durability of the separation substrate. Herein, a novel superhydrophilic and underwater superoleophobic polypropylene fabric (PPF) with regenerated degreasing cotton cellulose/silicon oxide (SiO 2) composite coating was successfully fabricated through simple dip coating strategy. The obtained PPF can be utilized as highly efficient membrane material of separating immiscible mixtures of water and oils. Furthermore, by pumping the water-prewetted PPF rolled into a tube, pure and corrosive water on oil is able to be steadily separated without any oil uptake. Especially, owing to the decrease of PPF pores after suffering from the composite coating, a series of oil-in-water (O-in-W) emulsions can be effectively filtrated (separation efficiency: >92.5%; water flux: >380.6 L·m−2·h−1). Compared with many filtration materials, the as-fabricated PPF is durable, low cost and the fabrication method can be scaled up for massive production of separation PPF. It is expected that the as-prepared PPF can be applied to deal with oily wastewater from daily life and industries. [Display omitted] • A polypropylene fabric (PPF) with cotton cellulose/SiO 2 composite coating was fabricated. • The decorated PPF can continuously remove water from oil. • The PPF is able to separate oil-in-water emulsion. • The PPF has high separation efficiency to oil-in-water emulsions.

Abstract: A sorption-active material carrying sulfonic acid groups was synthesized by the radiation-induced graft polymerization of styrene monomer onto the surface of non-woven polypropylene fabric, followed by sulfonation of the grafted polystyrene chains. The effect of the main experimental parameters (absorbed dose, monomer concentration, reaction time) on the styrene degree of grafting was investigated. The sulfonation process with 5% chlorosulfonic acid at room temperature was investigated in detail and the optimal sulfonation conditions for the samples with a medium degree of grafting (70–140%) were determined. Densities of 3.5–5meq/g were obtained by applying those sorption-active PP fabrics with a sulfonic acid group. [Copyright &y& Elsevier]

Cation-exchange adsorbent based on polypropylene nonwoven fabric carrying sulfonate functional groups was synthesized by radiation-induced graft polymerization of glycidyl methacrylate (GMA) with subsequent chemical modification of the epoxy groups of poly-GMA graft chains with sodium hydrogensulfite in water–dimethylformamide solution at 70 °C.The effect of various polymerization parameters on the GMA grafting degree as well as experimental conditions for the effective incorporation of sulfonate groups were investigated. The conversion of the epoxy groups into the functional groups was investigated as a function of the degree of GMA grafting. The ion-exchange characteristics of the resultant cation-exchange adsorbent were determined. [Copyright &y& Elsevier]

• Chemical analyses of H. italicum supercritical extracts are presented. • Arnazol was identified in supercritical extracts of Helichrysum genus. • Profiles of adsorbed components on cotton and polypropylene fabrics are presented. • The integrated supercritical extraction and impregnation process was applied. • Ethanol can be used to tailor the product properties in extraction and impregnation. ga1 Helichrysum italicum (Roth) G. Don fil., Asteraceae, possesses numerous secondary plant metabolites with a wide range of biological activities. Yet, data on the potential of supercritical fluid extraction (SFE) in their isolation are scarce. This study provides analyses of the chemical profiles of extracts obtained by SFE with or without ethanol as a cosolvent using GC-FID, GC-MS, HPLC, and UHPLC-MS techniques. Among the compounds with proven biological activity identified, the presence of arzanol was confirmed. In the next step, the integrated process of supercritical fluid extraction and impregnation was applied to deliver active compounds to cotton gauze and polypropylene fabric for possible topical applications. The analytical procedures results showed a considerable affinity of both textile materials for incorporating active components present in the H. italicum. The study indicated the high-pressure techniques applied as very efficient in the isolation of bioactive components from H. italicum and their adsorption on selected carriers. [ABSTRACT FROM AUTHOR]
