The IR dichroism technique is a convenient method which can be used to measure the molecular order parameter corresponding to the IR bands exclusively present in the disc –like molecules in discotic liquid crystal (DLC). To measure orientational order parameter, homeotropic alignment of discotic liquid crystal was attained by slow cooling of sample from isotropic phase on untreated flat CaF2 su...

Background: Infection is one of complication vascular access that can lead a higher morbidity, loss access, and even mortality. Hospitalized hemodialysis patients with double lumen catheter (DLC) have two to three risk for infection death compared arteriovenous graft. The aim this study was determine the rate in dialysis its characteristic. Method: A retrospective conducted Sanglah General Hosp...

The wear of atomic force microscope (AFM) tips is a critical issue in the performance of probe-based metrology and nanomanufacturing processes. In this work, diamond-like carbon (DLC) was coated on Si AFM tips using a plasma ion implantation and deposition process. The mechanical integrity of these DLC-coated tips was compared to that of uncoated silicon tips through systematic nanoscale wear t...

Two and three dimensional polymeric structures at the nano and micro scale are increasingly being incorporated into micro and nano scale devices. Soft lithography can be employed for the creation of templates where a polymer replica can be produced. Obtaining a master is one of the limiting factors in the production of such replicas. This study demonstrates pattern generation on a highly durabl...

1 Abstract— The special characteristics and singular properties of diamond-like carbon (DLC) thin films deposited by pulsed DC plasma enhanced chemical vapor deposition (PECVD), such as hardness and wear resistance, are suitable for self assembly applications as protective coating and as nanostructured surfaces. In this master thesis project, nanostructured DLC surfaces will be designed and cha...

BACKGROUND Src homology 2 (SH2) domain is a conserved module involved in various biological processes. Tensin family member was reported to be involved in tumor suppression by interacting with DLC-1 (deleted-in-liver-cancer-1) via its SH2 domain. We explore here the important questions that what the structure of tensin2 SH2 domain is, and how it binds to DLC-1, which might reveal a novel bindin...

nloaded Rho GTPase-activating protein DLC1 is a tumor suppressor that is often deleted in liver cancer and egulated in other cancers. DLC1 regulates the actin cytoskeleton, cell shape, adhesion, migration, and ration through its Rho GTPase-activating protein activity and focal adhesion localization. In this study, nced DLC1 in nonmalignant prostate epithelial cells to explore its tumor suppress...

Abstract Silica scale adhesion onto geothermal power plant equipment reduces the efficiency. In our previous study, diamond-like carbon (DLC) coatings with low sp 2 fractions and high hydrogen contents were found to suppress silica adhesion. Therefore, present study was aimed at clarifying mechanism of graphene-like network DLC. In-lens scanning electron microscopic imaging adhered defective gr...

Micro-hot-embossing is an emerging technology with great potential to form microand nano-scale patterns into polymers with high throughput and low cost. Despite its rapid progress, there are still challenges when this technology is employed, as demolding stress is usually very high due to large friction and adhesive forces induced during the process. Surface forces are dominating parameters in ...

Diamond like carbon (DLC) coatings have been proven to be an excellent choice for wear reduction in many technical applications. However, for successful adaption to the orthopaedic field, layer performance, stability and adhesion in physiologically relevant setups are crucial and not consistently investigated. In vitro wear testing as well as adequate corrosion tests of interfaces and interlaye...
