From Greenhouse Gas to 3-D Surface-Microporous Graphene（图）
Greenhouse Gas 3-D Surface Microporous Graphene
2017/9/1
A material scientist at Michigan Technological University invented a novel approach to take carbon dioxide and turn it into 3-D graphene with micropores across its surface. The process is the focus of...
The “International Forum on Surface and Microscopy, 2017” (IFSM 2017) symposium is the second special conference for optical microscopic imaging in China, bringing together professionals engaged in op...
Asphericity in the Fermi Surface of d and f-Shell Metals
Pseudopotential Asphericity in the Fermi Surface exchange and correlation effects
2010/4/8
Recently proposed pseudopotential has been used to calculate asphericity in the Fermi surface of d and f-shell metals along the three symmetry directions [100], [110] and [111]. The parameter of the p...
Stability of low-friction surface sliding of nanocrystals with rectangular symmetry and application to W on NaF(001)
low-friction surface sliding hexagonal lattices rectangular symmetry
2010/4/6
We investigate the stability of low-friction sliding of nanocrystal with rectangular atomic arrangement on rectangular lattices, for which analytical results can be obtained. We find that several inco...
Surface-Wave Instabilities in a Plasma Rotating with Step-like Frequency Profile
Magnetorotational instability Plasma rotational instability
2010/7/5
An approach for the theory of nonlocal magnetorotational and convective instabilities in a rotating plasma is developed, on the basis of the surface wave concept, which allows the derivation of useful...
Surface Characterization of Titanium Based Dental Implants
Titanium implants Dental implants Surface morphology
2010/9/29
The study of dental implant surfaces is relevant in order to better understand the interaction of the titanium
surface and the surrounding tissues. Clinical success is achieved not only because of im...
Dynamical Phase Transition in Vibrational Surface Modes
Dynamical phase transition Vibrational localized states Origin of frictional forces
2010/9/29
We consider the dynamical properties of a simple model of vibrational surface modes. We obtain the exact spectrum of surface excitations and discuss their dynamical features. In addition to the usuall...
Surface Charges and External Electric Field in a Toroid Carrying a Steady Current
Surface Charges External Electric Field a Steady Current
2010/10/27
We solve the problem of a resistive toroid carrying a steady azimuthal current. We use standard toroidal coordinates, in which case Laplace’s equation is R-separable. We obtain the electric potential ...
Pulsed Power Modulators for Surface Treatment by Plasma Immersion Ion Implantation
Pulsed Power Surface Treatment Plasma Immersion Ion Implantation
2010/10/27
The treatment of surfaces by plasma immersion ion implantation requires pulsed power modulators to provide negative high voltage pulses. To achieve this requirement, we have developed three basic circ...

Atomic Structure Energetic Stability the Bi--covered InAs(110) Surface
2010/10/21
We have performed ab initio calculations of the atomic structure and energetic stability of the Bi–covered InAs(110) surface. The calculations were performed within the density–functional theory, usin...
