- Abstract:
- ... Natural alginate fibers are used as templates to fabricate CoFe alloy-decorated hierarchically porous carbon fibers (HPCFs). Due to the coordination with negatively charged α−L−guluronate blocks, transition metal (TM) ions could be confined in the “egg box” structure of alginate, which convert to CoFe alloy particles that homogenously embedded in HPCFs during carbonization. The composition and wei ...

- Abstract:
- ... The development of transition metal nitrides/carbon hybrids with well-organized morphology, outstanding efficiency and durability for Zn-air batteries are of great urgency. Herein, a morphology-controlled strategy to efficiently fabricate uniform Co4N nanoparticles anchored on N-doped carbon (Co4N@NC-m) is reported. The diameters and distribution of Co4N nanocrystals can be tuned to be homogeneous ...

It highlights the reported degradation mechanisms which are responsible for the instability issue. These mechanisms are (a) oxidative attack of the ORR intermediates, (b) demetalation of the metal-active site, (c) ...

- Abstract:
- ... I demonstrate a directional motion-transmission behavior of aligned carbon nanotubes (CNTs) using atomistic simulations. The network of overlapping π orbitals at the interface act as gear teeth to translate the sliding motion of a CNT into a rotating motion of the adjacent CNT, or viceversa. The efficiency of this orthogonal motion transmission is found to strongly depend on the tube chirality, by ...

Specially, the morphology of the as-made HPC can be transf ...

This procedure provided a convenient tool to control the surface properties, such as polarity, and to make CNOs suitable for various applications. Two series of CNOs were produced using different temperatures (1150, 1450 and 1650 °C) an ...

We demonstrate the fabrication of self-aligned laser-reduced graphene oxide patterns with a spatial resolution/laser spot size ratio of 1/10, lower than anything reported before using laser-reduction. Laser light modifies graphene oxide (GO) by removing the oxygen-containing groups turning GO into a more graphene-like nanomaterial. Our method is based on high laser power density used for the reduc ...
