Introduction
Current commercial stacked capacitors are usually divided into two catalogues in terms of internal electrodes structure: one is based on parallel electrode structure for the purpose of enhancing the capacitance and the other is based on series electrode structure for the purpose of increasing the withstanding voltage.
Particularly, special attention would be paid to the interface structure and chemistry and the dielectric behavior of thus-fabricated capacitors.
The rest only sputtered gold film without sintering to form electrode structure 3 (ES-3).
Totally, 6 capacitors were manufactured and measured for each electrode structure.

The electronic structure, band structure and optical properties of Co,C co-doped AlN are investigated by first-principles calculations.
Introduction As a important III-V compound, AlN has a high breakdown voltage and high heat conductivity, It possesses two typical structures which is wurtzite structure and zinc-blende structure, the corresponding band gap is 6.20 and 5.11eV respectively.
These lead to the slight twist of the lattice structure and subsequently changed the electronic structure and optical property.
Band structure.

These properties make SBA-15- related materials the best
candidates for wide range of applications in catalysis, sorption, chromatographic separation and
host-guest chemistry.
In other words, the introduction of ZnO nanoparticles can impair and even destroy the ordered mesoporous structure.
The ZnO modification results in the change of pore structure.
Therefore, it can be concluded that both the porous structure of the material and the chemistry of the additive play significant roles for H2S capture.
The desulphurization capacities depend on the pore structure and the surface chemistry of the material.

The structure of NMC811 and silica-NMC811 were characterized using XRD (Fig. 3).
This is due to small amount of silica and its amorphous structure [5].
Characterization using XRD shows that silica coating does not affect the NMC811 crystal structure.

Nanoparticles transform to nano broccoli like-structure when Toluene inserted with X=10 (Fig. 4-b).
The tube like structure of stem contains several rods with the average size of 40 nm.
Thus, the Ti-OH bonds are more restricted and the result is formation of the tube-like structure.

Introduction
Over the last decade, great progress has been seen in the development of smart structures’ technology.
At present there are two distinct directions of computer material science development both dealing with ab initio level of calculation of material properties: band structure calculations based on translation periodicity of the crystalline media and cluster calculations similar to the quantum chemistry approach.
NWChem is a computational chemistry package designed to run on high-performance parallel supercomputers as well as conventional workstation clusters.
Atomic structure of cluster NiMn4Ga4, the constitutive element of L21 cubic form of Ni2MnGa.

Bismuth sulfide (Bi2S3) is a kind of layer-structured direct band gap semiconductor with an Eg of 1.3 eV.
When using ethanol as solvent, the product also contained the nanorods and the pine-like structure.
The size of these nanorods changed little, but the number of the pine-like structure was increased to 20%.

Molybdenumdisulphide (MoS2) has a lamellar structure, but with interlamellar bonding being between adjacent layers of S atoms.
This unexpected findings were believed to be caused by high porosity observed in the structure found from the sprayed MoS2 employed in this work (see Fig.1).

The TEM analysis is performed to observe the
dimensions, shape, and structure of the tubes.
If catalyst particle size is generally large, multiwall nanotubes are produced typically with cylindrical or bamboos like structure.
At this temperature well-structured tubes are formed.
