By easily transferring the Li 2s electrons to BC3, with the electron density mainly concentrated on the B atom (due to p-type behavior), and filling the usually empty pz state of the B atom, BC3 binds stronger to Li in comparison with graphite. BC3 sheets can provide a specific capacity...
Fig. 15. Structure of (a) diamond, and (b) graphite. (c) The ternary phase diagram for amorphous carbon-hydrogen alloys. Both types of film can, by appropriate choice of deposition conditions, be extremely uniform in thickness (with an intrinsic ‘roughness’ measured in tenths of nanometres...
Numerical calculations establish the conductivity diagram as a function of these two parameters, directly linking microstructures to electrical properties. Our work represents an important step towards understanding the structure–property relationship of amorphous materials at the fundamental level and paves ...

Fig. 6: A conceptual diagram illustrating the impact of warming on SOC formation and accrual and the underlying microbial mechanisms through plant C inputs, community succession, physiology adjustment and necromass production under conservation agriculture over decadal timescales. The main processes include...
Charge density distributions of DSPC at I vacancy thereby are clearly shown in Fig.3h, in which high local electron density is marked in yellow, and low electron density is marked in blue. It can be seen that there is a relatively high electron density around the oxygen atom with an ...
Electrocatalytic CO2 reduction reaction (CO2RR) is an attractive way to simultaneously convert CO2 into value-added fuels and chemicals as well as to store
1. A composite based on vinylidene polyfluoride, characterized in that it is constituted by a PVDF material covered at least partially by a copolymer possessing in its molecule an alternation of at least one ethylenic sequence and a carbonyl group in a chain of formula see diagramm : EP01916...
Schemic diagram of chaotic layer structure of carbon fiber: (a)defects and carbon atom at the edge of graphite lamella; (b)graphite microlite; (c)fibril; (d)ribbon structure; (e)stereo structure. A carbon fiber with 6 ~8 μm in diameter is composed of fibrils. Fibril is thin strip ...
The carbon-atom vacancies arranging randomly on the fcc carbon sublattice is called disordered phases, while the ordered carbon vacancies take on a periodic arrangement. The disordered state of non-stoichiometric carbides is in thermodynamic equilibrium only at a high temperature, whereas the ordered ...
