The present invention is directed to a method of forming a polymer coating on a substrate. The method comprising the steps of providing in an evacuated reaction chamber a substrate having a surface to be coated; and providing a first source of polymer forming material and a second source of radicals. According to the invention the first source and the second source are separated from each other and from the reaction chamber, and the polymer forming material as well as the radicals are, at least temporarily, conducted contemporaneously but spatially separated to the substrates surface, so that a reaction of the polymer forming material with the radicals is avoided before they reach the substrates surface. Further, the present invention is directed to a device for carrying out the method according to the invention.

INTERFACES is a supra-disciplinary training and research network that aims (1) to develop conceptual process understanding of the role of ecohydrological interfaces (i.e. system boundaries) for the transport and transformation of fluxes of heat, energy and water and interlinked biogeochemical cycles (C, N, O) at micro- to landscape-scale; and (2) to create the next generation of supra-disciplinary scientist that are able to work beyond traditional disciplinary boundaries, blend cutting-edge field, laboratory and modelling technologies, and understand the practical relevance of their research. Ecohydrological interfaces connect different environmental (sub-) systems and represent important new cross-disciplinary research domains to extend our knowledge horizons. Moreover, these environmental intersections offer an extremely fertile training ground because exploration of interface process dynamics requires novel linkage between traditionally distinct disciplines, and development of a supra-disciplinary research and training philosophy to foster the evolution of a new generation of scientists. Training and research will span novel distributed sensing technologies, innovative tracer methods and integrated numerical models of heat fluxes, metabolism, biogeochemical turnover and ecological functioning to understand how, when (hot moments) and why ecohydrological interfaces (e.g. aquatic-terrestrial, groundwater-surface water, marine-sediment interfaces) act as critical hotspots for water-dependent environmental processes. The urgently improved mechanistic process understanding developed by INTERFACES will not only provide industries, regulators and decision makers with the capacity to predict the complex, non-linear landscape-wide impacts of ecohydrological interfaces in a changing environment but also to understand how important ecosystem services provided by different ecohydrological interfaces can maintain or even enhance resilience to global environmental changes.

Rapidly developing markets such as green construction, energy harvesting and storage, advanced materials for aerospace, electronics, medical implants and environmental remediation are potential key application targets for nanomaterials. There, nanotechnology has the potential to make qualitative improvements or indeed even to enable the technology. Impacts range from increased efficiency of energy harvesting or storage batteries, to radical improvements in mechanical properties for construction materials. In addition, concerns of these markets such as scarcity of materials, cost, security of supply, and negative environmental impact of older products could also be addressed by new nano-enabled materials (e.g. lighter aircraft use less fuel). FutureNanoNeeds will develop a novel framework to enable naming, classification, hazard and environmental impact assessment of the next generation nanomaterials prior to their widespread industrial use. It will uniquely achieve this by integrating concepts and approaches from several well established contiguous domains, such as phylontology and crystallography to develop a robust, versatile and adaptable naming approach, coupled with a full assessment of all known biological protective responses as the basis for a decision tree for screening potential impacts of nanomaterials at all stages of their lifecycle. Together, these tools will form the basis of a value chain regulatory process which allows a each nanomaterial to be assessed for different applications on the basis of available data and the specific exposure and life cycle concerns for that application. Exemplar materials from emerging nano-industry sectors, such as energy, construction and agriculture will be evaluated via this process as demonstrators. The FutureNanoNeeds consortium is uniquely placed to achieve this, on the basis of expertise, positioning, open mindedness and a belief that new approaches are required.

A flame-resistant multi-layer composite (10) comprises a carbon-containing substrate (14); a first polymer layer (16) applied on the substrate in a first plasma-polymerization (pp-) process step; and a second polymer layer (18) applied on the first plasmapolymer layer in a second pp-process step. The pp-layers are of different composition. One of the pp-layers is obtained from plasma-polymerization of phosphorus-containing precursors or a mixture of precursors comprising phosphorus-containing precursors. The other pp-layer is obtained from plasma-polymerization of nitrogen-containing precursors or a mixture of precursors comprising nitrogen-containing precursors. The multi-layer composite may be used in intumescent, halogen-free, flame retardants. Improvements in both time-to-ignition (increase) and peak of heat release rate (decrease) were observed. The substrate could be any carbon-based polymer, flexible or rigid, in film, foam or fabric form. Deposition of the pp-layers can be performed at atmospheric pressure in open reactors, which facilitates implementing the production process on an industrial line.

While many epidemiological studies have associated the consumption of polyphenols within fruits and vegetables with a decreased risk of developing several chronic diseases, intervention studies have generally not confirmed these beneficial effects. The reasons for this discrepancy are not fully understood but include potential differences in dosing, interaction with the food matrix, and differences in polyphenol bioavailability. In addition to endogenous factors such as microbiota and digestive enzymes, the food matrix can also considerably affect bioaccessibility, uptake, and further metabolism of polyphenols. While dietary fiber (such as hemicellulose), divalent minerals, and viscous and protein-rich meals are likely to cause detrimental effects on polyphenol bioaccessibility, digestible carbohydrates, dietary lipids (especially for hydrophobic polyphenols, e.g., curcumin), and additional antioxidants may enhance polyphenol availability. Following epithelial uptake, polyphenols such as flavonoids may reduce phase II metabolism and excretion, enhancing polyphenol bioavailability. Furthermore, polyphenols may act synergistically due to their influence on efflux transporters such as p-glycoprotein. In order to understand polyphenol bioactivity, increased knowledge of the factors affecting polyphenol bioavailability, including dietary factors, is paramount. © 2014 International Life Sciences Institute.
