Article Synopsis
  • Lanthanum hydroxide nanorods served as both a template and catalyst to create hollow carbon nanorods with graphitic walls through chemical vapor deposition.
  • The resulting carbon structures formed a connected maze-like network, which boasts a high surface area of 771 m²/g due to accessible inner surfaces from broken ends.
  • When tested as an electrode for supercapacitors, these hollow carbon nanorods achieved a specific capacitance of 128 F/g, with an energy density of 55 Wh/kg and a power density of 1700 W/kg using a specific ionic liquid electrolyte.

Wrinkled mesoporous silica (WMS) has been shown to be a promising material for catalysis and drug delivery. The WMS possesses a unique wrinkled structure with conical shaped pores radiating from the center to the surface of each particle. Lanthanum oxide was supported on wrinkled mesoporous silica as a hard template for the synthesis of graphitic carbon.

Thermoacoustic performance of thin freestanding sheets of carbonized poly(acrylonitrile) and polybenzimidazole nanofibers are studied as promising candidates for thermophones. We analyze thermodynamic properties of sheets using transport parameters of single nanofibers and their aligned and randomly electrospun thin film assemblies. The electrical and thermal conductivities, thermal diffusivity, heat capacity, and infrared blackbody radiation are investigated to extract the heat exchange coefficient and enhance the energy conversion efficiency.

For the first time, porous organic polymers (POPs) based on the smallest buckybowl, corannulene (BB-POPs) have been synthesized. Three POPs were synthesised via Sonogashira co-polymerization of 1,2,5,6-tetrabromocorannulene and alkyne linkers. BB-POP-3 exhibits the highest surface area (SA = 560 m g) and CO adsorption of 11.
