This paper presents the microstructure, optical and electrical properties of zinc oxide nanorodlike structures deposed on glass substrate by dip-coating method. The crystalline phases and morphology of 1-D nanostructured materials have been investigated using X-ray diffraction and scanning electron microscopy (SEM) techniques. The UV-VIS-NIR spectra and the electrical properties were also measu...

A novel, aqueous precursor system (Pb(NO3)2 + water) is developed to replace conventional (PbI2 + DMF) for fabricating methylammonium lead iodide (MAPbI3) perovskite solar cells (PSCs). When the morphology and surface coverage of the Pb(NO3)2 film was controlled during coating, a power conversion efficiency of 12.58% under standard conditions (AM1.5, 100 mW cm(-2)) was achieved for the PSC.

Objective(S): Implant-related infections are disastrous complications in the clinic. One recent strategy to reduce the rate of infection is using the bioactive coating with an antibiotic. The purpose of these bioactive surfaces is to prevent bacterial adhesion to the implant and, consequently, the development of biofilm. In this study, vancomycin-loaded polymeric coating on imp...

Strategies that confine antibacterial and/or antifouling property to the surface of the implant, by modifying the surface chemistry and morphology or by encapsulating the material in an antibiotic-loaded coating, are most promising as they do not alter bulk integrity of the material. Among them, plasma-assisted modification and catechol chemistry stand out for their ability to modify a wide ran...

Thermal barrier coating are perceived as an enabling technology to increase the performance of, improve efficiency within, and lower the emissions from, modern gas turbines. To fully utilise this capability one has to be able to accurately predict the life of these coatings under conditions relevant to gas turbine service. This paper addresses the failure of TBC systems as a result of erosion a...

Organic-inorganic nanohybrids have been synthesized by in situ coating supramolecular nanotubular J-aggregates with helically wound silica ribbons, reflecting the J-aggregates' superstructure. The J-aggregates retain their morphology and optical properties in the nanohybrids, and display improved stability against elevated temperatures, chemical ambient and photo-bleaching.

Immediate loading of dental implants is only possible if a firm bone-implant anchorage at early stages is developed. This implies early and high bone apposition onto the implant surface. A nanostructured coating material based on an osseoinductive bone grafting is investigated in relation to the osseointegration at early stages. The goal is to transmit the structure (silica matrix with embedded...

In this work, Fluoropolymer-based ultrathin coating is evaluated as a protective barrier for Printed Circuit Board (PCB) against corrosion failures. Constant humidity with temperature cycling was applied external climatic conditions performance assessment through electrochemical AC impedance and DC potentiostatic measurements. Morphology of the before after test inspected using Optical, Scannin...
