ZnO/SiC heterojunctions show great potential for various optoelectronic applications (e.g., ultraviolet light emitting diodes, photodetectors, and solar cells). However, the lack of a detailed understanding of the ZnO/SiC interface prevents an efficient and rapid optimization of these devices. Here, intrinsic (but inherently n-type) ZnO were deposited via molecular beam epitaxy on n-type 6H-SiC...

Silicon carbide composites (SiC/SiC) are promising candidate materials for fusion reactors. For the practical application of this class of materials, a design basis for SiC/SiC composites needs to be developed because of inherent brittle-like fracture, i.e., quasi-ductility, which is totally different from ductility of metals. For this purpose, the failure behavior, i.e., matrix cracking behavi...

Silicon carbide (SiC) an industrial-scale product manufactured through the Acheson process, is largely employed in various applications. Its toxicity has been poorly investigated. Our study aims at characterizing the physico-chemical features and the in vitro impact on biological activity of five manufactured SiC powders: two coarse powders (SiC C1/C2), two fine powders (SiC F1/F2) and a powder...

Integrating an advanced manufacturing technique, nanocomposite material and controlled delivery of growth factor to form multifunctional tissue engineering scaffolds was investigated in this study. Based on calcium phosphate (Ca-P)/poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) nanocomposite microspheres, three-dimensional Ca-P/PHBV nanocomposite scaffolds with customized architecture, control...

Nystatin is a tetraene diene polyene antibiotic showing a broad spectrum of antifungal activity. In the present study, we prepared a nystatin nanocomposite (Nyst-CS-MNP) by loading nystatin (Nyst) on chitosan (CS) coated magnetic nanoparticles (MNPs). The magnetic nanocomposites were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimet...

The present work was targeted to design a surface against cell seeding and adhering of bacteria, Bacillus subtilis. A multi-walled carbon nanotube/titanium dioxide nano-power was produced via simple mixing of carbon nanotube and titanium dioxide nanoparticles during the sol-gel process followed by heat treatment. Successfully, quercetin was immobilized on the nanocomposite via physical adsorpti...

Multiwalled carbon nanotube (MWCNT) arrays have been directly synthesized from templated Fe2O3 nanoparticles on the C-face of 4H-SiC substrates by microwave plasma chemical vapor deposition (MPCVD), and the room-temperature thermal resistances of SiC-MWCNT-Ag interfaces at 69–345 kPa as well as the thermal resistances of SiCMWCNT-Ag interfaces up to 250 C (at 69 kPa) have been measured using a ...

SiC single crystal is usually grown by sublimation (modified Lely method). There is a lotof remaining issues that should be solved. One is the technical problems of SiC single crystal growth process. And the other is the theoretical problem based on SiC physical properties. As the example of technical issues, in this paper, the example of design optimization for SiC sublimation growth is descri...

This paper presents a vision for the future of 3D packaging and integration of silicon carbide (SiC) power modules. Several major achievements and novel architectures in SiC modules from the past and present have been highlighted. Having considered these advancements, the major technology barriers preventing SiC power devices from performing to their fullest ability were identified. 3D wire bon...

Recently, energy saving is strongly required to prevent global warming. Electricity is the most common energy form and is necessary in our daily life and various activities, because it is comparatively easy to utilize in transmission and conversion after generation. Therefore, it is very important to reduce energy loss in electric power systems and improve their efficiency. The present power sy...
