Microstructure in graphite nodules plays a fundamental role in mechanical properties in cast iron. Traditional measures used to study spheroid graphite are nodules density, nodularity, volume fraction and mean size. However, sometimes these parameters do not permit a good characterization of the microstructure since they do not allow the discrimination of different regions. In fact, other measu...

Novel graphite-molybdenum carbide nanocomposites (G-Mo2C) are synthesized by a typical solid state reaction with melamine and MoO3 as precursors under inert atmosphere. The characterization results indicate that G-Mo2C composites are composed of high crystallization and purity of Mo2C and few layers of graphite carbon. Mo2C nanoparticles with sizes ranging from 5 to 50 nm are uniformly supporte...

Recently it has been found that the structure of Skyrmions has a close analogy to that of fullerene shells in carbon chemistry. In this letter we show that this analogy continues further, by presenting a Skyrme field that describes a lattice of Skyrmions with hexagonal symmetry. This configuration, a novel ‘domain wall’ in the Skyrme model, has low energy per baryon (about 6% above the Faddeev-...

In order to study a possible magnetic proximity effect in magnetite-carbon structures, we have performed magnetization measurements of graphite-magnetite composites with different mass ratios as well as the measurement of the magnetoresistance of one of them and of the magnetization of a magnetite-carbon bilayer. The overall results do not indicate the induction of bulk ferromagnetism in graphi...

A broad review of recent research work on the preparation and the remarkable properties of intercalation compounds of graphite, covering a wide range of topics from the basic chemistry, physics and materials science to engineering applications.

Graphite has long been the most used commercial anode material in Li-ion batteries. However, it has a limited Li intercalation capacity of 372 mAh g , which cannot meet the increasing energy demand for Li-ion batteries. Here, we propose massive artificial graphite as a host material for the controlled deposition and stripping of Li metal within the internal space of the particles and demonstrat...

With the objective of implementing graphite calorimetry at the BIPM to measure absorbed dose, an experimental assembly has recently been constructed to measure the specific heat capacity of graphite. A status description of the apparatus and results from the first measurements are given. The outcome is discussed and the experimental uncertainty is reviewed.

A suitable grinding fineness and flow-sheet could potentially reduce the mechanical entrainment of gangue minerals in the flotation process of microcrystalline graphite. In this study, the suitable grinding fineness of a commercial graphite ore was estimated by mineralogy analysis and laboratory grind-flotation tests. The target grind size of this ore should be 92% passing 74 μm based on the mi...

This thesis describes Graphite, a parallel, distributed simulator for simulating large-scale multicore architectures, and focuses particularly on the functional aspects of simulating a single, unmodified multi-threaded application across multiple machines. Graphite allows fast simulation of multicore architectures by leveraging computational resources from multiple machines and making efficient...
