AB  - Impact resistant nanocomposites are recognized as promising in saving lives in the car, skiing and bicycle accidents, preventing the failure of polymer-based prostheses and orthotic devices, as well as for various defense applications. This research reports improved impact and ballistic resistance of composite materials based on p-aramid fabric impregnated with phenolic resin and poly (vinyl butyral) (PVB), reinforced with small amounts of inorganic fullerene-like nanoparticles of tungsten disulfide (IF-WS2) and multiwall inorganic nanotubes (INT-WS2). The evaluation of the tensile testing resulted in significant improvements in the tensile strength (24.7%) and toughness (64.1%) for the composites with the addition of only 0.3 wt% INT-WS2 nanotubes. The impact toughness increased by 35.8%; the back-face deformation depths after shots were reduced by 12%; the absorbed energy of the knife stab 8.5% higher and the deformation depth 40.4% smaller than for the sample without the nanoreinforcement. The reaction of the composite material to shot impact was recorded by high-speed and infrared camera, to observe heating and cooling rates of the sample caused by dissipation of the kinetic energy of the shots.

AB  - Pure manganese coatings were prepared on the steel (AISI 4340) electrode by a non-conventional electrodeposition method, in the presence of 8 mol dm(-3) of urea as a plating additive. The influence of urea on the electrodeposition of Mn was investigated by cyclic voltammetry. The morphology of the coatings was studied by scanning electron microscopy (SEM), and their elemental composition by energy dispersive X-ray spectrometry (EDS). The results showed that the presence of urea in the solution increased the current efficiency for metal reduction for around 20%, and depending on the applied deposition potential, urea may act either as a complexing agent or through the adsorption mechanism. Moreover, urea improves the characteristics of Mn deposits, i.e. their adhesiveness, porosity, compactness, and appearance. Except for oxygen, as part of the Mn corrosion product at the coating surface, no carbon or nitrogen incorporation was detected in the deposits by EDS.
