چکیده
The superiority of coronary stent implantation over percutaneous transluminal balloon angioplasty in virtually all lesion subsets has led to the wide use of stents for the percutaneous treatment of coronary lesions 1,2. However, in-stent restenosis remains as a major limitation 3,4. Recent data suggest that neointimal proliferation, the cornerstone of in-stent restenosis 5,6, is related to the presence of thrombus and degree of inflammation at the stent site7. A potential approach for the prevention of neointimal proliferation is the use of amorphous silicon-carbide (a-SiC), an inactive substance known to have antithrombotic and anti-inflammatory properties 8,9. By coating stents with a-SiC, hemoand biocompatibility of stent prostheses is enhanced, potentially reducing neointimal proliferation. Therefore, the purpose of the CERAMIC trial (randomized intravascular ultrasound Comparison between EndopRostheses with and without AMorphous sIlicon-Carbide for the prevention of coronary restenosis) was to determine whether a-SiC-coated stents prevent intrastent neointimal proliferation in humans.

Interface modification effect between p-type a-SiC:H and ZnO:Al in p-i-n amorphous silicon solar cells
Aluminum-doped zinc oxide (ZnO:Al) [AZO] is a good candidate to be used as a transparent conducting oxide [TCO]. For solar cells having a hydrogenated amorphous silicon carbide [a-SiC:H] or hydrogenated amorphous silicon [a-Si:H] window layer, the use of the AZO as TCO results in a deterioration of fill factor [FF], so fluorine-doped tin oxide (Sn02:F) [FTO] is usually preferred as a TCO. In th...

At room temperature, 300 K, silicon carbide film was formed using monomethylsilane gas on the reactive surface prepared using argon plasma. Entire process was performed at reduced pressure of 10 Pa in the argon plasma etcher, without a substrate transfer operation. By this process, the several-nanometer-thick amorphous thin film containing silicon-carbon bonds was obtained on various substrates...
