OBJECTIVE We quantitatively investigate the biocompatibility of chemical vapour deposited (CVD) nanocrystalline diamond (NCD) after the inclusion of boron, with and without nanostructuring. The nanostructuring method involves a novel approach of growing NCD over carbon nanotubes (CNTs) that act as a 3D scaffold. This nanostructuring of BNCD leads to a material with increased capacitance, and th...

At present, the technology of obtaining diamond films on silicon and other substrates is well studied. However, in all published works to date, there has been no report a layer carbide formed between film substrate. The presence (15R-SiС)1-x(Cdiamond)x structure was revealed studies structures with obtained by us chemical vapor deposition. Diamond were single-crystal (111) orientation n-type co...

Diamond and diamondlike carbon (DLC) films exhibit a wide range of sometimes contradictory tribological behavior. Experimentally, isolating the influences of factors such as film structure, testing conditions, and environmental effects has proven difficult. In this work, molecular dynamics simulations were used to examine the effects of film structure, passivation, adhesion, tribochemistry, and...

Conductive boron-doped diamond thin-film electrodes were used for the electrochemical detection of selected N-methylcarbamate pesticides (carbaryl, carbofuran, methyl 2-benzimidazolecarbamate, bendiocarb) after liquid chromatographic separation. Two kinds of detection methods were adopted in this study. In the first method, a direct detection of underivatized pesticides was carried out at an op...

Radiographic or silver halide film is a well-established 2D dosimeter with an unquestioned spatial resolution. But its higher sensitivity to low-energy photons has to be taken into consideration. Metal compensators or physical modulators to deliver intensity modulated radiation therapy (IMRT) are known to change the beam energy spectrum and to produce scattered photons and contaminating electro...

Diamond-coated tools often fail due to coating graphitization and delamination caused by poor adhesion, large contact stress, thermochemical reactions. To address these issues, this research utilized a combination of micro-nano double-layer diamond coating, WS2 micro-textures. The inhibits the through transfer film mechanism, while micro-textures nanocrystalline store WS2, resulting in prolonge...

The effect of substrate temperature on the morphology of diamond films grown by chemical vapor deposition is examined. Under some conditions increasing substrate temperature causes the film morphology to shift from {100} toward {111} faceting, whereas under other conditions exactly the opposite trend is observed. It is found that the factor that differentiates these two regimes is the abundance...
