The aim of this work was to synthesize TiC reinforced coating on carbon steel via reduction of ilmenite powder. A mixture of ilmenite and graphite was pre-placed on AISI 1020 steel surface. The effect of the addition of excess graphite amounts on the progress of synthesis of carbide particles was studied. The evolution of phases in different coatings was analysed via X-ray diffraction and scann...

In this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of Ag colloid in the range of 500-16000 ppm. Nanoparticles were deposited by spin coating method on pre-etched glass and Si substrates. Structural, optical and electrical properties of the samples were studied using Scanning Electron Microscopy equipped with EDAX, UV-Vis spectroph...

Background: Infection remains among the main reasons for joint prosthesis failure. Preclinical reports have suggested that antibacterial coatings of implants may prevent bacterial adhesion and biofilm formation. This study presents the results of the first clinical trial on an antibiotic-loaded fast-resorbable hydrogel coating (Defensive Antibacterial Coating, DAC®) in patients undergoing hip o...

Alveolar defects of a critical size cannot heal completely without grafting. Thus, they represent a major clinical challenge to reconstructive surgery. Numerous types of grafts have been used to improve bone regeneration. In the case of particle grafts, the capacity for volume rebuilding and space maintaining is still not ideal, particularly for critical-sized bone defects. Although porous bloc...

The present study was conducted to evaluate the combined effect of low-dose gamma irradiation and antimicrobial coating on the shelf life of pre-cooked shrimp (Penaeus spp.). Antimicrobial coatings were obtained by incorporating various concentrations of thyme oil and trans-cinnamaldehyde in coating formulations prepared from soy or whey protein isolates. Coated shrimps were stored at 4 +/- 1 d...

In this study, effects of pre-oxidation on the hot corrosion behaviour Al–Si coatings in a Na2SO4 and 25 w/% NaCl mixture at 900 °C were investigated. The results showed that after 120 h corrosion, large amount β-NiAl residual was found with no obvious sulphides or oxidation pre-oxidised coating. pre-formed oxide film coating prevented external O2– species such as S2– Cl– from molten salts dire...

Objectives: The goals of this 4-year project were extended gradually from developing alternative apple coatings to three additional goals: (1) Evaluate flavor of major apple varieties using GC and electronic nose during CA storage and simulated marketing for documentation of changes due to storage time, temperature, atmosphere, and 1-MCP pre-treatment (to determine flavor life as opposed to she...

Hot-pressed aluminium and silicon coated boron steel is used in the car industry where high tensile strength is of great importance, such as in the safety cage of a car where deformation has to be kept to a minimum in case of a collision. After hot-pressing the AlSi-boron steel shows excellent properties with high tensile strength, minimal spring back and also shows good protection against corr...

PURPOSE Optimized biocompatibility is a major requirement for alloplastic materials currently applied for stress urinary incontinence (SUI) and pelvic organ prolapse (POP) repair. In the preliminary studies the mesh modification by coating with autologous plasma resulted in the increased adherence score in vitro and improved biocompatibility in an animal model. The first use of plasma coated me...
