The conditions of the synthesis were analogous to those applied for the alytic growth of pristine MWCNT arrays (which were also synthesized here for comparison and referred to as Ref. Synthesis, Scheme 1), except that Pz, – the additional heteroaromatic nitrogen precursor, which decomposes into acetylene, hydrogen cyanide and cyanoacetylene at 760 C – was introduced into the feedstock.

Structural characterization of liquid phase sintered silicon …

Silicon carbide (SiC) was sintered using two different additives: AlN-Y 2 O 3 or AlN-CRE 2 O 3. CRE 2 O 3 is a mixed oxide formed by Y 2 O 3 and rare-earth oxides. The crystalline structures of the phases were analyzed by high-resolution X-ray diffraction using synchrotron light source.

The influence of impurities and planar defects on the …

Two cubic, single crystal silicon carbide (3C-SiC) films with similar thickness are shown to exhibit significantly different optical properties at mid-infrared wavelengths. Depth profiling by time-of-flight secondary ion mass spectroscopy indies that these two films have substantially different n-type impurity concentrations that are responsible for the observed differences in optical

Minimized lithium trapping by isovalent isomorphism for …

Silicon demonstrates great potential as a next-generation lithium ion battery anode because of high capacity and elemental abundance. However, the issue of low initial Couloic efficiency needs to be addressed to enable large-scale appliions. There are mainly two mechanisms for this lithium loss in the first cycle: the formation of the solid electrolyte interphase and lithium trapping in

A simulation method to estimate microstructure dependent material properties and their influence on performance for a honeyco structured SiC heating element has been established. Electrical and thermal conductivities of a porous SiC sample were calculated by solving a current continuity equation. Then, the results were used as input parameters for a finite element analysis package to predict

Facile Synthesis of Nanoporous Amorphous Silica on …

Large-scale nanoporous amorphous silica nanostructure is fabried via a simply etched approach and effective thermal evaporation process. The nanoporous amorphous silica was synthesized by a general and scalable process via etching by metal particles on the silica sheets. In this study, we elucidated how a nanoporous structure was performed and the addition of indium is the key factor that

20/7/2020· In this paper, we demonstrate quality factor (Q) enhancement of a silicon RF MEMS resonator by cryogenic cooling from room temperature down to liquid nitrogen temperatures (78K). The resulting Q is approximately 63,000 at a frequency of 3.72 GHz, yielding an f-Q product of 2.34×10 14 Hz. This work verifies that the resonator is operating in the Landau-Rumer regime at room temperature, …
