Dual

Graphite is used in high-temperature gas-cooled reactors because of its outstanding irradiation performance and corrosion resistance. To restrict its high-temperature (873 K) oxidation, atmospheric-plasma-sprayed SiC-ZrB2-Al2O3-carbon nanotube (CNT) dual-layer coating was deposited on graphite substrate in this work. The effect of each layer was isolated by processing each component of the

Structural analysis of highly porous γ

2014/9/1Two highly porous γ-aluminas, a commercial catalyst obtained from the calcination of boehmite and a highly mesoporous product obtained from amorphous aluminum (oxy)hydroxide via a sol–gel-based process were investigated by 27 Al nuclear magnetic resonance (NMR), transmission electron microscopy (TEM), and atomic pair distribution function (PDF) analysis of synchrotron powder

Cubic γ

2020/11/1In the present study, the cubic γ-Al 2 O 3 coating was synthesized via non-electrode plasma electrolysis for the modification of graphite powder. The thin coating (50 nm) delayed the initial oxidation temperature and ended oxidation temperature by ~80 C and ~110 C, respectively as well as reducing the oxidation rate of the powder.

Facile Dry Coating Method of High‐Nickel Cathode

We present a facile and fast dry powder coating method of high‐nickel NMC701515 by nanostructured fumed γ‐Al 2 O 3. In the high intensity mixing process, the coverage of the CAM surface strongly depends on the applied amount of coating material.

Enhanced physical properties of γ

In this study, a solvothermal method was employed for the first time to fabricate hybrids composed of cross-linked γ-Al2O3 nanorods and reduced graphite oxide (rGO) platelets. After calcination and hot-press processing, monoliths of Al2O3–rGO hybrids were obtained with improved physical properties. It

(IUCr) Structure model of γ

The defect structure of γ-Al2O3 produced from boehmite is described with the aid of antiphase and rotational boundaries. The type of structure defects is deduced from the selected-area electron-diffraction patterns. The defect density is quantified from the anisotropic broadening of diffraction lines in powder X-ray diffraction patterns using a computer routine based on the Debye scattering

Preparation of Al2O3

2018/10/1Expanded graphite (EG) having a dimension of 26.35 nm 4.26 nm can be seen in Fig. 2a.The bond length of C–C was set to be 1.42, C–C–C bending angles was 120 . An Al 2 O 3 layer with the same dimension was put ~ 0.2 nm above the EG surface. The Al 2 O 3 model was built base on Digne's work on γ-alumina (see Fig. 2b).

Structured Pd/γ

The preparation of a coating procedure was studied, from the washcoating with i#x3b3;/i-alumina to the deposition of palladium by excess solvent or incipient wetness impregnation. The powder and the washcoat layers were studied by different characterisation techniques such as SEM, BET surface area, and XRD. Vibration-resistance and heat-resistance were also evaluated. It was shown that

Graphene

Graphene (/ ˈ ɡ r f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of graphite and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
