Metals are common construction materials for heat exchangers. However, metals may suffer from failure due to corrosion, especially in harsh environments. Innovative thermally conductive polymer composite tubes based on polypropylene or polyphenylene sulfide filled with graphite have been developed. Crystallization fouling metal surfaces has extensively studied. data very limited. In the current...

This paper deals with the effect of melamine cyanurate on thermal and fire retardant behaviour chopped glass fibre (40 wt.%) reinforced polyphenylene ether/polystyrene/nylon-6 (40/40/20 wt. %) which are processed in a twin screw co-rotating extruder. The composite specimens were fabricated by injection moulding. Addition decreased amount toxic gases organic volatile compounds, crystallinity, cr...

This work studied the mix mode-I/II fracture behaviour of an aerospace-grade carbon fibre/epoxy composite that was interlayer-toughened by Polyamide-12 (PA), Polyphenylene-sulphide (PPS), Polyimide (PI), Polyethersulfone (PES) and Polyethylenimine (PEI) fibres. During laminate curing process, PA fibres melted, PPS PI kept in their original form PES PEI dissolved epoxy matrix. resulted different...

Rigid dendrimers with flexible ferrocenyltriazolyl termini serve as excellent supports for remarkably efficient and recyclable Pd Au nanocatalysts biphasic reduction of 4-nitrophenol to 4-aminophenol at 20 °C.

Nonadiabatic molecular dynamics simulations, involving multiple Born-Oppenheimer potential energy surfaces, often require a large number of independent trajectories in order to achieve the desired convergence of the results, and simulation relies on different parameters that should be tested and compared. In addition to influencing the speed of the simulation, the chosen parameters combined wit...
