Nowadays, polymer-based carbon-plastics confidently displace common tribotechnical and structural materials (steel, aluminum, titanium, etc.) in the automotive, metallurgical, agricultural industries. It happens due of fact that surpass steel aluminum 5 7 times, respectively terms strength, they are also characterized by low weight ease processing. An equally important factor is possibility man...

Abstract Tailoring the functionality of Polyether-ether-ketone (PEEK) is critical for enhancing its application, which can be accomplished by modification surface morphology and chemistry. In present work, we experimentally demonstrate correlation modified chemical composition textured PEEK 355 nm UV nanosecond pulsed laser ablation with enhanced wettability. Specifically, impact processing par...

Abstract One of the open questions in cold spraying on fibre reinforced composites is optimal thickness top layer to provide a suitable base for successful deposition metallic particles and at same time hinder probable damage fibres. In this study, detailed finite element model developed study deformation single Cu particle polyether ether ketone (PEEK) substrate with carbon A PEEK 30, 40 or 60...

This article investigates the surface electrical properties of polyether-ether-ketone (PEEK) and cross-linked polyethylene (XLPE) before after fluorination modification. The samples are tested for conductivity, morphology, antiaging characteristics. also flashover voltage with ramping under 100, 20, 10 kPa. results showed that surfaces PEEK XLPE become slightly smoother increase in time conduct...

Abstract Plasma-enhanced heterogeneous catalysis offers a promising alternative to thermal for many industrially relevant processes. There is only limited mechanistic understanding about the relation between interactions of highly energetic electrons and excited molecules with catalysts in plasma their catalytic performance. Herein, novel operando infrared spectroscopy cell presented allowing i...

Abstract High-performance polymers (HPPs) are increasingly used in different industrial machinery components, particularly for rubbing parts that demand reliable and durable operation at extreme sliding conditions such as elevated temperature environments, where the use of conventional lubricants is not feasible. The current study investigates role environmental on tribological properties three...

So far, hydrogen compatibility of polymer materials was investigated, focusing on gaining insight in general degradation mechanisms. However, this is not yet sufficient for purposes safety and performance requirements, example, the automotive industry especially, corresponding advanced material development, which needs meaningful comprehensive data prospective long time intervals. Therefore, he...

O-Demethylabierixin, a new polyether antibiotic, was isolated from a Streptomyces spp. Its structure elucidation was carried out with fast atom bombardment mass spectrometry (FAB-MS) and fast atom bombardment mass spectrometry-mass spectrometry (FAB-MS/MS) by comparing spectral patterns with those of structurally similar polyether compounds, nigericin and abierixin. The collision-induced dissoc...
