Reciprocating micro-scale sliding tests and repetitive impact were performed with diamond probes on un-doped, Si-doped W-doped diamond-like carbon (DLC) coatings hardened steel a nanomechanical test instrument. Analytical modelling showed that differences in coating behaviour during contact could be interpreted by the stress distribution develops. The softer DLC exhibited lowest wear resistance...

Abstract Diamond-like carbon (DLC) films directly deposited on rubber substrate is undoubtedly one optimal option to improve the tribological properties due its ultralow friction, high-hardness as well good chemical compatibility with rubber. Investigating relationship between film structure and performance vital for protecting In this study it was demonstrated that etching effect induced by hy...

1 Introduction Demand response (DR) refers to a set of dynamic demand mechanisms that aim to manage electricity consumption in response to supply-side signals. DR can be used for the purpose of demand regulation (e.g. to maintain voltage and frequency within safety limits) as well as for energy balance (e.g. to shift demand to off-peak periods, to curtail demand during emergency situations, or ...

Powdered lead oxide (Pb3O4) is used in the wooden-boat repair industry as a constituent of the caulking material. This study compared skin lead of household members of caulkers’ and control homes, and examined the relationship of household member’s skin lead with household floor lead loading (FLL) and dust lead content (DLC). FLL and DLC were measured in 67 caulkers’ houses and 46 nearby houses...

The aim of the present study was to investigate the biological role and molecular mechanism of the deleted in liver cancer-1 (DLC-1) gene in human colon cancer growth and invasion. Recombinant lentiviral vectors encoding the DLC-1 gene were constructed for transfection into the human colon cancer cell line SW480. Real-time quantitative polymerase chain reaction (real-time qPCR) and western blot...

The low hardness and poor tribological performance of aluminum alloy as moving component greatly restricts their wide applications in automotive fields. In this letter, an attempt to deposit gradient Ti/TiN/Si/(TiC/a-C:H) multi-layer on aluminum alloy is thus effectively performed by a combined arc ion plating and magnetron sputtering process based on the concept of involving coatings with a fu...

Deleted in liver cancer-1 (DLC-1) has been isolated from primary hepatocellular carcinoma and demonstrated to be a potential tumor suppressor gene. The aim of the present study was to observe the effect of the DLC-1 gene on pancreatic cancer cell growth and evaluate the feasibility of using the DLC-1 gene in gene therapy for pancreatic cancer. A recombinant plasmid (pcDNA3.1/DLC-1) was transfec...

A top DLC film was deposited on the surface of Cr3C2-NiCr coated 38CrMoAl steel substrate, and effect cermet interlayer thickness mechanical tribological properties duplex coating investigated by experimental analysis finite element modeling (FEM). Results shown that, compared with single film, load-bearing capacity performance DLC/Cr3C2-NiCr were significantly improved, especially its anti-wea...
