This experimental study aims to energetically and exergetically compare the performance of a PVT system with sheet-and-plain serpentine tube collector (base system) two cases modified systems. The systems are replacements plain rifled 3 ribs (3-start 6 (6-start system). electrical parameter PV module without cooling is compared three cooling. fluid water/magnetite nanofluid. effect nanofluid fl...

This research reports the antifriction and antiwear properties of Mn3O4-Graphene nanocomposites (Mn3O4-G) as additives a paraffinic base oil commonly used in formulation electric vehicles transmission oils, G-III oil. Four nanodispersions have been designed, + 0.025 wt% Mn3O4-G, 0.050 0.075 Mn3O4-G 0.100 to know optimal concentration nanoadditive. Tribological experiments were carried out with ...

Abstract In this study, a robust macroscale liquid superlubricity with coefficient of friction 0.004 was achieved by introducing molybdenum carbide (Mo 2 CT x ) MXene nanoparticles as lubricating additives in lithium hexafluorophosphate-based ionic at Si 3 N 4 —sapphire interfaces. The maximal contact pressure the state could reach 1.42 GPa, which far exceeds limit regime previous studies. resu...

In the present study, graphene oxide (GO) was incorporated as a nanoadditive into a polyphenylsulfone (PPSU) to develop a PPSU/GO nanocomposite membrane with enhanced antifouling properties. A series of membranes containing different concentrations (0.2, 0.5 and 1.0 wt.%) of GO were fabricated via the phase inversion method, using N-methyl pyrrolidone (NMP) as the solvent, deionized water as th...

In this paper, we studied the effect of different carbon-based nanostructures on electrical and mechanical properties polypropylene (PP) nanocomposites. Multi-walled carbon nanotubes (MWCNT), expanded graphite (EG), two black nanoparticles (CB) have been dispersed at several weight contents in polymer matrix through a melt extrusion process. The produced nanocomposites used to obtain samples fo...

In this study, the effect of copper oxide (CuO) with different sizes on heat-induced catalysis decomposition typical molecular perovskite-based energetic material DAP-4 was studied. Pure CuO and are characterized by X-ray diffraction (XRD) scanning electron microscopy (SEM). Heat-induced performances adding were investigated differential calorimeter (DSC). Results demonstrated that a lower-addi...
