S’il est reconnu dans la littérature que les eaux résiduaires urbaines véhiculent une charge en microplastiques (MP) importante, la contamination des dépôts de réseaux d’assainissement et des rejets urbains de temps de pluie restait jusqu’à lors inexplorée, malgré une contamination potentiellement importante. Les concentrations observées pour les dépôts (entre 5×103 à 178×103 particules/kg de sédiment sec) témoignent en effet qu’une partie des microplastiques véhiculées par les eaux usées peut sédimenter. Indépendamment du polymère considéré, la sédimentation d’une partie des microplastiques a

Resumen
Abstract Improved oil recovery methods are essential to fulfill the world’s energy needs and maximize oil recovery from older oilfields. In order to boost the viscosity of injection water and enhance sweep efficiency, high molecular weight polymers, such as partially hydrolyzed polyacrylamides (HPAMs) are injected in a technique known as polymer flooding, which is a potential EOR technique. However, obstacles like excessive salinity and high temperatures can make polymer flooding less successful. In order to increase viscosity, thermal stability, and oil recovery results, recent research has c

Low-temperature, polymer-based fuel cells and water electrolyzers using anion conductive polymers have several potential advantages over acid-based polymer electrolyzers. However, the long-term durability of the ion conducting polymer has not been investigated to the same extent as proton conducting polymers. Further, accelerated aging test conditions with known acceleration factors have not been developed. In this study, a family of poly(norbornene) polymers used in fuel cells and electrolyzers was aged under a variety of conditions to determine the aging rate and acceleration factors. In par

Crystalline and amorphous dispersions have been the focus of academic and industrial research due to their potential role in formulating poorly water-soluble drugs. This review looks at the progress made starting with crystalline carriers in the form of eutectics moving towards more complex crystalline mixtures. It also covers using glassy polymers to maintain the drug as amorphous exhibiting higher energy and entropy. However, the amorphous form tends to recrystallize on storage, which limits the benefits of this approach. Specific interactions between the drug and the polymer may retard this

Pour des raisons environnementales et de santé publique, la remédiation des sites et sols pollués est impérative. Une des techniques in-situ utilisées pour dépolluer des sols présentant une pollution aux hydrocarbures, est l’utilisation de mousse liquide. Grâce à son effet bloquant, la mousse crée une barrière entre l’eau et le polluant, et facilite le pompage de celui-ci. La principale problématique de cette technique est la stabilité de la mousse face à l’huile.

Abstract Conjugated organic polymers are intrinsic semiconducting materials that exhibit enhanced conductivity upon oxidation or reduction. The unusual nature of this class of organic polymers was brought into particular focus in the late 1970s with the first example of conductivity values in the metallic regime, for which the 2000 Nobel Prize in Chemistry was awarded to Hideki Shirakawa, Alan MacDiarmid, and Alan Heeger. As such, it is generally believed that these materials are a relatively recent advancement and originated with this polyacetylene work in the 1970s. This accepted narrative,

Resumen
Abstract Water soluble polymers for internal boiler treatment should prevent precipitation of scaling salts and allow the formation of a very thin, corrosion protective film on heat transfer surfaces. Parameters controlling the performance of polymers will be presented and discussed. In particular, the effect of polymer molecular weight, complexing ability, chemical composition and thermal stability will be addressed.

Resumen
Abstract The development of environmentally friendly cure chemistries which can be used to make polymers is a major area of focus in the polymer industry [1]. One area of particular interest to the DoD and Army Corps of Engineers is the development of biobased epoxies and amines which can be used as an alternative to petrochemical based building blocks to make biobased epoxy-amine coatings for the corrosion protection of various substrates. In this presentation, the corrosion performance of epoxy-amine primers under development is assessed by a combination of electrochemical measurements and a

Resumen
Polyurethane technologies have demonstrated their applications in a variety of seamless polymer flooring systems. Aliphatic polyurethanes are widely used as topcoats since they provide combinations of good color stability, gloss retention, abrasion resistance, chemical resistance, and weathering resistance. Recent development in polyaspartic chemistry offers more options in coating thickness, curing temperatures, and solids content. Aromatic polyurethanes are used in resilient coatings and modified concretes due to their flexibility, toughness, and thermal shock resistance. This article will d

Resumen
Abstract With the advent of polymeric materials, various uses for these materials have been discovered in the quest to best utilize their unique characteristics. One property that a few polymers possess is hydrophobicity; that is water repelling. Consequently, one particular use for hydrophobic materials is in the area of corrosion protection. When applied as a coating material, hydrophobic polymers, theoretically, should provide excellent protection against corrosive environments. In order to ascertain the performance of hydrophobic materials in corrosion service, metallic substrates of alumi

Abstract Chemicals being discharged into the environment are increasingly under scrutiny for environmental impact. New chemicals being brought to the market place, for scale and corrosion control, are likely to be influenced by developing legislation and regulations. Studies of thermal Polyaspartate, a 'green inhibitor', have found it to be an excellent Squeeze control additive for barium and calcium sulphate inhibition. Adsorption and coreflood studies demonstrate the good surface active properties of this thermal Polyaspartate that leads to long squeeze lifetimes. Good calcium compatibility

Resumen
Abstract The use of polymer based chemical inhibitors has the advantage of utilizing chemical, macromolecular, and compositional (blends or block copolymers) towards chemical inhibitors whether it is for corrosion or scaling issues. It is important to understand the multi-phase condition of production fluids whether it is extraction or circulation (oil and gas vs geothermal brine). It is also important to understand the mechanism and the long-term action of inhibition from the fluid to the surface that is being protected.

Resumen
Abstract Due to the increase in need for combustibles, in particular oil, sweet hydrocarbon reservoirs are fast becoming depleted. This has led to the need to tap into sour reservoirs. The presence of hydrogen sulfide (H2S) in the reservoirs has presented new challenges to oil production companies. Among these challenges is determining the effect of H2S on elastomeric seals used in oil production systems. This paper examines the effect of H2S on both the mechanical and chemical properties of elastomers commonly used in the petrochemical industry. Exposures to an extreme aggressive environment

Resumen
Manufacturing applications for filled polymers include encapsulation of microelectronics and injection molding of composite parts. Predictive tools for simulating these manufacturing processes require knowledge of time- and temperature-dependent rheology of the polymer as well as information about local particle concentration. The overall system rheology is highly dependent on the particle concentration. The local particle concentration can change due to gravity, convection and shear-induced migration. For the epoxy systems of interest, an extent of reaction can be used to track the degree of

Resumen
In the transformation operations of polymeric materials, there is a complex interplay between transport phenomena and crystallization. In particular, the polymer in the molten state is a viscoelastic fluid with rheological parameters depending on temperature, pressure, crystallinity, and molecular stretch. The molecular stretch is a tensor variable with values determined by the history of the flow, temperature, and pressure fields. During polymer processing operations, several phenomena proceed simultaneously by interacting with each other. The combination and interplay of the models that desc
