A simple approach is proposed for obtaining low threshold field electron emission from large area diamond-like carbon (DLC) thin films by sandwiching either Ag dots or a thin Ag layer between DLC and nitrogen-containing DLC films. The introduction of silver and nitrogen is found to reduce the threshold field for emission to under 6 V/μm representing a near 46% reduction when compared with unmod...

Thin films, used in various applications and devices, must strongly adhere to their substrates. Due to various processing and storage environments that devices can be exposed to, water may be introduced into the system. If residual stresses are present in a thin film, delamination propagation can be driven by water without the assistance of an externally applied mechanical force. It is extremel...

Diamond-like carbon (DLC) coatings were deposited on Ti alloy (Ti-13Nb-13Zr) substrates using the plasma immersion process. The plasma immersion process, unlike the conventional techniques, allows the deposition of DLC on three-dimensional workpieces with high adhesion. We quantitatively evaluated the adhesion of fibroblasts on DLCcoated and uncoated Ti alloy at 2 h. Comparisons between sample ...

PVD diamond-like-carbon (DLC) coatings are finding increasing industrial acceptance in automotive, aerospace and medical applications due to their reduced friction and low wear coefficient. Very recently, High Power Impulse Magnetron Sputter (HIPIMS) sources have been shown to produce fluxes with very high metal ion fractions similar to those produced by arc evaporation sources, without showing...

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...

Diamond-like carbon (DLC) coatings are widely used in industries that require high durability and wear resistance, low friction. The unique characteristics of DLC allow for the possibility creating adsorption sites lubricant additives through doping process. In this study, combined use europium-doped diamond-like (Eu-DLC), gadolinium-doped (Gd-DLC), pure an ionic liquid (IL) additive, namely, t...

Acidithiobacillus ferrooxidans type strain DLC-5, isolated from Wudalianchi in Heihe of Heilongjiang Province, China. Here, we present the draft genome of strain DLC-5 which contains 4,232,149 bp in 2745 contigs with 57.628% GC content and includes 32,719 protein-coding genes and 64 tRNA-encoding genes. The genome sequence can be accessed at DDBJ/EMBL/GenBank under the accession no. JNNH0000000...

A discotic liquid crystal (DLC), HBC-C12, coating was successfully applied to improve the corrosion resistance of an iron surface. The iron surface with the DLC-coating exhibited improved corrosion resistance in various environments, including exposure to air and solutions with different pH values. To the best of our knowledge, studies regarding corrosion protection using DLCs have never been r...

Background This economic evaluation quantifies the cost-effectiveness of early laparoscopic cholecystectomy (ELC) versus delayed laparoscopic cholecystectomy (DLC) in the management of acute cholecystitis. The two interventions were assessed in terms of outcome measures, including utilities, to derive quality-adjusted life years (QALYs) as a unit of effectiveness. This study hypothesizes that E...

Introduction: SIMS analysis is widely used for Genesis sample measurements at various institutions, but only two laboratories [1,2] offer accelerator-based SIMS. The use of a tandem accelerator allows for breakup of molecules during the acceleration process, thus assuring removal of molecular interferences without significant loss in sensitivity. Additionally, both mass spectrometers [1,2] are ...
