Summary: Core shell nanocomposites based on SWCNT/PPy were fabricated and the optimum formula for maximum TE performance was determined. The core shell nanocomposite showed significantly enhanced TE power factor and figure of merit compared to pure PPy. This enhancement was attributed to the good interaction between PPy polymer chains and walls of the SWCNT.

Summary: A programmable shear-induced dynamic assembly approach was developed to synthesize mesoporous carbon nanospheres with tunable core-shell structures and gradient pore systems. The micelle structures in the system can be adjusted by changing shear force and a programmatically proceeded synthesis process results in intelligent assembly of multimodal mesostructures. The resultant carbon nanospheres exhibit high capacity and ultra-long cyclic life for sodium-ion storage, showing potential for innovative applications.

Summary: By using the self-assembly principle, carbon spheres (CS) with high load-bearing capacity were wrapped with molybdenum disulfide (MoS2) to form C@MoS2 particles, which were then dispersed into PAO 40 to enhance its anti-friction and wear-resistant capabilities. The excellent tribological properties of C@MoS2 particles were attributed to the synergistic lubrication between bearing and filling effect of CS as well as the superior antifriction capacity of MoS2 shell.

Summary: The directed core-shell motif hybridization of COFs on MOFs results in selectively functionalized carbonaceous precursors, TiO2@COF, with titanium dioxide nanoparticles in the inner core and nitrogen-rich carbon in the outer shell. This design provides abundant faradic active sites and nitrogen dopants, as well as favorable cycling stability and enhanced pseudocapacitive capacity. Additionally, the interconnected COF-derived fibers contribute to increasing electrical conductivity of the material, leading to a high salt adsorption capacity and favorable cycling stability for CDI electrodes.
