Abstract Nickel nanoparticle–decorated reduced graphene oxide nanocomposites (NiG) were prepared by a one-step microwave-assisted solvothermal method. The as-prepared NiG nanocomposite systems further heated up to 800 °C under an inert atmosphere (named NiG-800) modify their structural and electromagnetic properties. Thereafter, these developed NiG-800 of rGO nickel nanoparticles (25 wt.%) appl...

Wearable flexible sensors have developed rapidly in recent years because of their improved capacity to detect human motion wide-ranging situations. In order meet the requirements flexibility and low detection limits, a new pressure sensor was fabricated based on electrospun barium titanate/multi-wall carbon nanotubes (BTO@MWCNTs) core-shell nanofibers coated with styrene-ethylene-butene-styrene...

The mechanical properties and morphology of polypropylene/wood flour (PP/WF) composites with different impact modifiers and maleated polypropylene (MAPP) as a compatibilizer have been studied. Two different ethylene/propylene/diene terpolymers (EPDM) and one maleated styrene-ethylene/butylene-styrene triblock copolymer (SEBS-MA) have been used as impact modifiers in the PP/WF systems. All three...

Polymer nanocomposites have attracted increased attention for use in the field of high-voltage direct current (HVDC) cable insulation. To study polymer this purpose, 3D flower-like MgO (flower-MgO) particles with hierarchical surface morphology are first synthesised. Polypropylene (PP) was simultaneously mixed styrene-(ethylene-co-butylene)-styrene triblock copolymer (SEBS) and flower-MgO to ob...

• Soft-elastic baffles (SEBs) intensified mixing in a soft-elastic reactor (SER). A best design of SER with SEBs was identified. Mixing SERs large length to diameter ratios by SEBs. (SER) has been demonstrated as an alternative approach effective viscous liquid. Here, the performance Newtonian fluid—glycerin water solutions (1200±50 mPa⋅s) experimentally investigated for first time inside simpl...

Complicated nano-patterns with linewidth less than 18 nm can be automatically hammered by using atomic force microscopy (AFM) tip in tapping mode with high speed. In this study, the special sample was thin poly(styrene-ethylene/butylenes-styrene) (SEBS) block copolymer film with hexagonal spherical microstructures. An ordinary silicon tip was used as a nano-hammer, and the entire hammering proc...

Polypropylene (PP) compounds with styrene–butadiene rubber residue (SBRr) from the footwear industry were produced, adding styrene-(ethylene–butylene)-styrene (SEBS) as a compatibilizer, 20% and 30% of styrene (St.). The PP/SBRr PP/SBRr/SEBS processed in co-rotating twin-screw extruder injection molded. addition SBRr did not compromise processability, torque melt flow index increased slightly c...

O resíduo vulcanizado de estireno-butadieno (SBRr) proveniente da indústria calçados foi reaproveitado como modificador impacto compostos à base poliamida 6 (PA6). copolímero SEBS-MA e a argila montmorilonita foram incorporados aditivos compatibilização reforço, respectivamente. Os processados em um misturador interno moldados por injeção. As propriedades reometria torque, resistência ao impact...

Current earth observation models do not take into account the influence of water salinity on the evaporation rate, even though the salinity influences the evaporation rate by affecting the density and latent heat of vaporization. In this paper, we adapt the SEBS (Surface Energy Balance System) model for large water bodies and add the effect of water salinity to the evaporation rate. Firstly, SE...

Abstract This article investigates changes in student teachers’ teacher self-efficacy beliefs (SEBs) as part of their competence development during three-year bachelor’s program and how these can be explained through practical learning opportunities. Using two cohorts who studied prior to COVID-19, differences the are analyzed longitudinally over three time points. Unexpectedly, no increase SEB...
