Here we present atomistic-based multi-scale simulation studies of a magnetically active array of carbon nanotubes to illustrate the concept of mechanomutability. We show that applying external fields, it is possible to change the nanostructure and to induce a desired mechanical response. Direct numerical simulations are reported that illustrate this concept via mechanical testing through nanoin...

Nitrogen-doped hierarchical porous carbons were synthesized successfully by a controllable one-pot method using glucose and dicyandiamide as carbon source and nitrogen source via hydrothermal carbonization process. The nitrogen-doped materials, possessing high nitrogen content (up to 7 wt%), large surface area (>320 m(2) g(-1)) and excellent hierarchical nanostructure, were employed as catalyst...

The nanostructure of poly(acrylic acid) (PAA) adsorption layer on the surface of mesoporous-activated carbon HPA obtained by physical activation of residue after supercritical extraction of hops was characterized. This characterization has been done based on the analysis of determination of adsorbed polymer amount, surface charge density, and zeta potential of solid particles (without and in th...

A new method is described for large-scale production of Single Wall Carbon Nanohorns (SWCNH). In a prototype reactor (a 30 kW plant for an estimated production of about 100 g/h of soot) optimal thermodynamic conditions that favour nanohorn formation were determined. The characterization of collected soot was performed by several techniques: thermogravimetric analyses (TGA), Raman spectroscopy, ...

• Investigates the shock wave propagation and attenuation in CHC via MD simulation. Explores effects of vacancies temperature on CHC. Calculates critical intensity Due to its periodic porous structure high mechanical strength, carbon honeycomb (CHC), a new allotrope, possesses energy absorption capability thus great potential for design fabrication advanced impact-resistant materials. In this w...

Abstract We report the electrical, mechanical and electromagnetic interference (EMI) shielding performance of polypropylene random copolymer (PPR)/multi-wall carbon nanotube (MWCNT) nanocomposites enabled via customized fused filament fabrication process. The electro-conductive PPR/MWCNT feedstocks were fabricated shear-induced melt-blending process that allows 3D printing nanoengineered compos...
