Exfoliated Graphite Nanofibers for Hydrogen Storage

Exfoliation of graphite nanofibers (GNF) expands the interplanar spacing of the GNF which leads to increased hydrogen storage. The exfoliation technique plays a large role in the resulting GNF microstructure, surface area, and hydrogen storage properties. Variations in preparation conditions expand the GNF lattice from 3.4 Å to over 500 Å. The BET surface area of the exfoliated GNF increases as...

Lithium insertion in ball-milled graphite

The effects of mechanical milling on the microstructure, morphology and electrochemical performance of graphite powders with respect to lithium insertion are studied. After 150 h of ball-milling, the well-graphitized graphite has been pulverized into small particles with a size of about 50 nm, in which there are a lot of excess vacancies, microcavities and metastable carbon interstitial phases ...

A hydrogen storage nanotank: lithium-organic pillared graphite.

From first-principle based grand canonical Monte-Carlo simulations, we propose a new hydrogen storage material, lithium-organic pillared graphite, showing high H2 uptake of 4.0 wt% and 41.9 kg m(-3) at 300 K and 100 bar.

Analysis of Mechanically Milled Exchange Coupled Nanocomposite Permanent Magnets

Nanocomposite permanent magnets have recently evoked wide interest because of their interesting properties. They usually consist of a hard magnetic phase having superior coercivities and a soft magnetic phase having improved values of magnetization and when they are coupled together, we get a permanent magnet with enhanced values of both the parameters and thus can be put to a lot of applicatio...
