Nanoimprint lithography NIL has proven to be an exceptional lithographic technique for achieving arbitrary, nanoscale features, over large areas without the use of costly step-and-repeat UV lithography tools. One requirement for NIL is to eliminate adhesion of the imprinted polymer to the imprinter upon withdrawal of the imprinter. Previous work on thick 100 nm diamondlike carbon DLC layers ind...

Objective: To compare the cost-effectiveness of early laparoscopic choleystectomy (ELC) versus delayed laparoscopic cholecystectomy (DLC) in patients with acute cholecystitis. Design: A decision-tree model was developed using a series that modelled all potential outcomes for both treatment options. Probabilities were estimated from a Cochrane review. Costs were based on the UK National Schedule...

The diamond-like carbon (DLC) films deposited on the articulating surface of medical-grade Ti and Ti–6Al–4V were characterized. The DLC films were synthesized by r.f. plasma assisted chemical vapor deposition (PACVD) using C6H6 at 10 mTorr. For wear tests, the ball-ondisk type wear tester was employed by wearing a 5-mm diameter ruby ball against a rotating metal disk. The DLC coating dramatical...

Tribological coatings of yttria stabilized zirconia (YSZ), gold, diamond like carbon (DLC) and MoS2 were synthesized using magnetron assisted pulsed laser deposition (MSPLD). The coatings were synthesized in four-component and three-component combinations that included YSZ/Au/DLC/MoS2, YSZ/Au/MoS2, and YSZ/Au/DLC. A range of coating compositions was studied to explore coating optimization for l...

Pure carbon(C), nitrogen(N) and titanium(Ti) doped diamond-like carbon (DLC) coatings were deposited on silicon (Si) micro-molds by dc magnetron sputtering deposition to improve the tribological performance of the micro-molds. The coated and uncoated Si molds were used in injection molding for the fabrication of secondary metal-molds, which were used for the replication of micro-fluidic devices...

BACKGROUND A double-lumen catheter (DLC) is used as a temporary blood access in emergency haemodialysis and continuous haemodialysis. There are various reports concerning thrombosis related to use of DLC and other catheters. The objective of this study is to assess the incidence of venous thrombosis when using DLC in patients undergoing blood purification. Method. Forty-eight Japanese patients,...

AlGaN/GaN Schottky Barrier Diodes (SBDs) employing the Diamond-like Carbon (DLC) passivation was proposed. The reverse blocking characteristics of the AlGaN/GaN SBD is degraded by the electron trapping effect through the surface trap states. In order to suppress the electron trapping effect and increase the breakdown voltage of AlGaN/GaN SBDs, the surface passivation or treatment should be perf...

The current status of diamond-like carbon (DLC) coatings for biomedical applications is reviewed with emphasis on load-bearing coatings. Although diamond-like carbon coating materials have been studied for decades, no indisputably successful commercial biomedical applications for high load situations exist today. High internal stress, leading to insufficient adhesion of thick coatings, is the e...

PURPOSE The deleted in liver cancer-1 (DLC-1) gene that encodes a Rho GTPase-activating protein with tumor suppressor function is located on chromosome 8p21-22, a region frequently deleted in prostate carcinomas. This study was designed to determine whether DLC-1 is deregulated in prostate carcinomas and to assess the contribution of DLC-1 alterations to prostate carcinogenesis. EXPERIMENTAL ...

Deleted in liver cancer-1 (DLC-1) is a RhoGTPase-activating protein (RhoGAP) domain containing tumor suppressor that is often down-regulated in various cancer types. Previously, we have shown that DLC-1 is recruited to focal adhesions by binding to the Src homology 2 domains of tensins and the focal adhesion localization is critical for the tumor suppression activity of DLC-1. To investigate wh...
