    Article citation info: STAWECKI, W., MERKISZ, J., BAJERLEIN, M., DASZKIEWICZ, P. New technologies of enhanced plastic for use in rail vehicles to reduce noise emissions. Combustion Engines . 2017, 171 (4), 145-149. DOI: 10.19206/CE-2017-424 Włodzimierz STAWECKI CE-2017-424 Jerzy MERKISZ Maciej BAJERLEIN Pawel DASZKIEWICZ New technologies of enhanced plastic for use in rail vehicles to reduce noise emissions The article presents an overview of modern plastics for use in rail vehicles. The analysis of plastics and composites in the constructional aspect was analyzed. The trends in the development of polymer materials, technologies and constructions used in the manufacture of vehicles, on the one hand, are determined by the technical and economic requirements of industry and, on the other, by the continued emphasis on reducing fuel consumption and CO 2 emissions. Further development will be subject to pre-impregnation techniques, particularly in the form of different types of reinforcement. Full use of the advantages of reinforced polymer materials in vehicle production will only be achieved when further optimization of the resin properties and development of automation will result in the widespread use of composite components in series production. Observing the trends and pace of development, it is possible to predict that there are still restrictions on the use of polymeric materials in the transport sector, such as relatively high prices, technological constraints and the hindering automation of large-scale production. Modern construction and material solutions, in particular those using reinforced plastics, are primarily designed to reduce vehicle weight and have better noise and vibration damping properties.

    materials Article Hydroxide Conduction Enhancement of Chitosan Membranes by Functionalized MXene Lina Wang 1,* and Benbing Shi 2,* 1 College of Chemistry and Chemical Engineering, Xi’an University of Science and Technology, Xi’an 710054, China 2 School of Chemical Engineering & Technology, Tianjin University, Tianjin 300072, China * Correspondence: [email protected] (L.W.); [email protected] (B.S.) Received: 7 September 2018; Accepted: 17 November 2018; Published: 21 November 2018 Abstract: In this study, imidazolium brushes tethered by –NH2-containing ligands were grafted onto the surface of a 2D material, MXene, using precipitation polymerization followed by quaternization. Functionalized MXene was embedded into chitosan matrix to prepare a hybrid alkaline anion exchange membrane. Due to high interfacial compatibility, functionalized MXene was homogeneously dispersed in chitosan matrix, generating continuous ion conduction channels and then greatly enhancing OH− conduction property (up to 172%). The ability and mechanism of OH− conduction in the membrane were elaborated based on systematic tests. The mechanical-thermal stability and swelling resistance of the membrane were evidently augmented. Therefore, it is a promising anion exchange membrane for alkaline fuel cell application. Keywords: functionalized MXene; chitosan; anion exchange membrane; hydroxide conductivity; alkaline fuel cell 1.

Hydrogels with three-dimensional network structure, hydrophilic, and insoluble in water which are ideal carrier materials for intelligent drug delivery systems. Intelligent hydrogel has become a research frontier and hotspot because of its intelligence, high efficiency, safety, and convenience in drug controlled and prolonged release. It has a broad application prospect in the medicine and biomedicine fields and can lead the medicine fields into a new era of “precise treatment.” Based on the latest research progress, the main preparation methods of hydrogel and the development of the drug delivery system are briefly introduced. The most promising three intelligent hydrogels in the human physiological environment, namely, pH responsiveness, temperature responsiveness, and pH/temperature dual responsiveness, are emphatically reviewed.

Today, the main economic driver for waste electrical and electronic equipment (WEEE) recycling stems from metal recovery. WEEE plastics recycling, on the other hand, still represents a major challenge. Strategies like design ‘for’, but also the much younger concept of design ‘from’ recycling play a key role in closing the material loops within a circular economy. While these strategies are usually analysed separately, this brief report harmonises them in comprehensive Design for Circularity guidelines, established in a multi-stakeholder collaboration with industry leaders from the entire WEEE value chain. The guidelines were developed at the product and part levels. They are divided in five categories: (1) avoidance of hazardous substances; (2) enabling easy access and removal of hazardous or polluting parts; (3) use of recyclable materials; (4) use of material combinations and connections Citation: Berwald, A.; Dimitrova, G.; allowing easy liberation; (5) use of recycled materials.
