The ground state of D2 on graphene and graphite was a √3×√3 commensurate structure that upon a pressure increase was transformed into a so-called γ phase, characterized by an oblique unit cell rotated a given angle with respect to the axis of the upper graphene sheet. At even higher...
of the hexagonal phase because it has been reported that the silica structure is hexagonal in absence of oil [6]. The oil concentration is now raised in small increments, keeping the proportion of the other components constant. InFig. 4, we show simulation snapshots of three different ...
The magnetic properties of a quasi two-dimensional superconductor, Sn-metal graphite (MG), are studied using DC and AC magnetic susceptibility. Sn-MG has a unique layered structure where Sn metal layer is sandwiched between adjacent graphene sheets. This compound undergoes a superconducting transition...

As a result, it was clarified that (1) ADI has special spheroidal graphites which have the possibility to induce stress concentration on the micron order because of the wedgewise precipitation of carbon into the ferrite layer at the interface of graphite and matrix ; (2) at low stress ...
% cobalt. The crystal structure is of the D85 type, and the lattice constants were determined as a = 4.666 ± 0.005 kX, c = 25.6 ± 0.02 kX. At high temperatures, the ε-phase is in equilibrium with β-Co, but at1200°C a new phase, denoted θ, is formed peritectoidally, and...
Based on the state equation suggested the velocity of shock wave is shown to be a linear function of the material velocity behind the shock wave, the function being a specific characteristic of the material and its structure. Most significant anomaly belonging to carbon, iron, ice, and water ...

Phases are physically homogeneous states of an alloy. A phase has a precise chemical composition – a certain arrangement and bonding between the atoms. This structure of atoms imparts different properties to different phases. We can choose the phase we want and use it in our applications. Only...
