This flexible binder free carbon nanofibers/graphene/silicon electrode consists of millions of heart-coronary arteries cells. Besides, in the graphene/silicon “hearts”, graphene network improves the electrical conductivity of silicon nanopaticles, buffers the volume change of silicon, and prevents them...

The honeycomb structure of carbon, graphene, has a planar structure because the sp2 hybridization is favourable for that system. Si and Ge prefer sp3-type bonding hence buckling is observed with a height difference between two sublattices. As shown in Fig. 1(a), energetically, Pb layers could...
Particle imaging of ignition and devolatilization of pulverized coal during oxy-fuel combustion Oxy-fuel combustion of coal is a promising technology for cost-effective power production with carbon capture and sequestration that has ancillary benefits... CR Shaddix,A Molina - Elsevier Inc. 被...
In this regard, a particular focus is set on the most powerful analytical tools to study the structure of hard carbons (upon de-/sodiation) and a critical discussion on how to interpret and perform such analysis. Targeting the eventual commercialization of hard carbon anodes for sodium-ion ...
This paper reports results of turbostratic pyrolytic carbon structure study using high-resolution electron microscopy techniques. We obtained a through-focus series of images and noted that domain-like contrast features were varied depending on defocus of the objective lens. Since these features are comm...
This work corroborates the hierarchical conceptual model for soil aggregate structure presented by Tisdall and Oades (1982), extends it to North American grassland soils, and elaborates on the aspects relating to the influence of cultivation upon losses of soil organic matter. Aggregate size distribu...
The various existing materials are presented and a short overview of the carbonization and graphitization processes is given, with an emphasis on the defects which may arise from the finite size of the crystallites, from the increased distance between the carbon layers, and from their non-...
of the activated carbon material can be described by Bangham kinetic equation,and the adsorption rate of activated carbon fibers increases with specific surface area and pore size.The adsorption rates of GAC are slower than ACF,and the SO2adsorption properties of GAC are worse than ACF due to ...
