This study examines MWCNTs-PG nanofluid with a uniform dispersion of MWCNTs in PG. It is assumed that both MWCNTs and PG exist thermally in equilibrium and no slip occurs between them. MWCNTs were suspended in PG uniformly and played a significant role. Firstly, the problem is formulated by utilizing empirical correlations, thermophysical attributes, and similarity equations. Then the model is treated numerically along with the coupling of a shooting algorithm. The results against the pertinent flow quantities were plotted and provide a basis for a comprehensive discussion, investigating whether MWCNTs-PG has high thermal storage characteristics under the effects of thermal radiation and combined convection effects. Due to their high energy storage capability, these fluids are reliable for industrial applications.

We demonstrate a novel approach to controlling and stabilizing magnetic skyrmions in ultrathin multilayer nanostructures through spatially engineered magnetostatic fields generated by ferromagnetic nanorings. Using analytical modeling and micromagnetic simulations, we show that the stray fields from a Co/Pd ferromagnetic ring with out-of-plane magnetic anisotropy significantly enhance the Néel-type skyrmion stability in an Ir/Co/Pt nanodot, even stabilizing the skyrmion in the absence of Dzyaloshinskii-Moriya interactions. We demonstrate precise control over the skyrmion size and stability.

Carbon aerogels and xerogels, with their 3D porous architectures, ultralow density, high surface area, and excellent conductivity, have emerged as multifunctional materials for energy and environmental applications. This review highlights recent advances in the synthesis of these materials polymerisation, drying, and carbonisation, as well as the role of novel precursors such as graphene, carbon nanotubes, and biomass. Emphasis is also placed on doped and metal-decorated carbon gels as efficient electrocatalysts for oxygen reduction reactions, enabling four- and two-electron pathways for energy conversion and the production of green HO, respectively.

The donor/acceptor (D/A) interfaces in bulk heterojunction (BHJ) organic solar cells (OSCs) critically govern exciton dissociation and molecular diffusion, determining both efficiency and stability. Herein, we design a double-cable conjugated polymer, SC-1F, to insert into a physically-blended D/A system to optimize the interface. We have found that SC-1F spontaneously segregates to the interface through favorable miscibility and heterogeneous nucleation with the acceptor.

The metal-nitrogen chelated species, MN, have shown promise as efficient electrocatalysts for nitrate reduction, yet the symmetric arrangement of N atoms results in suboptimal adsorption affinity toward reaction substrates and intermediates. The current approaches to breaking the symmetry of MN suffer from inaccuracy and inhomogeneity because of the lack of strategies stemming from molecular design aspects. Herein, we report the construction of symmetry-broken MNO sites in coordination polymers via sequential coordination-covalent control in a one-pot reaction.
