A quenchable superhard high-pressure carbon phase was synthesized by cold compression of carbon nanotubes. Carbon nanotubes were placed in a diamond anvil cell, and x-ray diffraction measurements were conducted to pressures of approximately 100 GPa. A hexagonal carbon phase was formed at approximately 75 GPa and preserved at room conditions. X-ray and transmission electron microscopy electron d...
This paper examines the challenge posed by the measurement of thickness of sub-50 nm diamond-like carbon (DLC) films deposited onto silicon substrates. We compared contact profilometry (CP), optical profilometry (OP), contact atomic force microscopy (CAFM), tapping atomic force microscopy (TAFM) and X-ray reflectometry (XRR). Generally, CP, CAFM, TAFM and XRR give similar thickness values excep...
Diamond-like carbon (DLC) is considered as a versatile coating material that finds a variety of mechanical and biomedical applications, including endoprosthesis and dental implants [1]. It provides mechanical robustness and cell-compatibility at the same time. Therefore, DLC has been extensively researched for achieving high hardness, low friction, high wear resistance to make it more sustainab...
