Polymer bulk hetero-junction solar cells of poly(3-hexylthiophene) (P3HT) donor and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) acceptor are fabricated by blade coating in toluene solution. Desired donor–acceptor self-organization is achieved without the slow drying process and high boiling point solvent. Power conversion efficiency is 3.8%, much higher than the 2.6% obtained by spin coat...

Near infrared spectra combined with partial least squares were proposed as a means of non-contact analysis of the adsorptive ink capacity of recording coating materials in ink jet printing. First, the recording coating materials were prepared based on nano silica pigments. 80 samples of the recording coating materials were selected to develop the calibration of adsorptive ink capacity against i...

Interface delamination is the major weakness limiting diamond coating tool performance in machining. Thus, quantitative characterizations of the interface behavior are important to better understand and design diamond coating tools. In this study, we attempt to apply a cohesive zone model to investigate the coating-substrate interface behavior. The cohesive zone model is based on the traction-s...

Collagen and apatite were coprecipitated as a composite coating on poly L-lactic acid (PLLA) in an accelerated biomimetic process. The incubation solution contained collagen (1 g/L) and simulated body fluid with 5 times inorganic ionic concentrations as human blood plasma. The coating formed on PLLA films and scaffolds after a 24-h incubation was characterized by using energy-dispersive X-ray s...

A carbon nanotube-enhanced SiC (CNT-SiC) coating was deposited on C/C composites to improve the oxidation resistance of C/C. The CNT-SiC coating was prepared by direct growth of CNTs on C/C surface at 700oC followed by deposition of SiC using chemical vapor deposition at 1150oC for 1 hour. SiC was deposited on the CNTs as well as the interface between CNTs and C/C, making CNTs strongly rooted o...

In this study, a comprehensive effect of particle loading and optimised process parameter on the developed zinc electrolyte was presented. The depositions were performed between 10-30 min at a stirring rate of 200 rpm at room temperature of 30 °C. The effect of coating difference on the properties and interfacial surface was acquired, at a voltage interval between 0.6 and 1.0 V for the coating ...

BACKGROUND The use of different bioactive materials as coating on dental implant to restore tooth function is a growing trend in modern Dentistry. In the present study, hydroxyapatite and the bioactive glass-coated implants were evaluated for their behavior in osseous tissue following implantation in 14 patients. MATERIALS AND METHODS Bioactive glass and hydroxyapatite formulated and prepared...

in this work, the effect of erosion on corrosion behavior of coal tar epoxy coating was evaluated usingelectrochemical impedance spectroscopy (eis) measurements. the surface morphology of the coatingwas examined by scanning electron microscope (sem) after 10, 20, 30, 45 and 60 min of erosion processat an impact angle of 90º. after 10 min of erosion process, the nyquist plots showed just a singl...

Protein adsorption to capillary walls is one of the major complications in protein analyses with capillary electrophoresis (CE). Coating the capillary with different materials is used to reduce the adsorption. This chapter overviews different approaches used for capillary coating and concentrates on those utilizing Si-O and Si-C covalent bonds. The apparatus and methods are presented for capill...

On-chip microparticle and cell coating technologies enable a myriad of applications in chemistry, engineering, and medicine. Current microfluidic coating technologies often rely on magnetic labeling and concurrent deflection of particles across laminar streams of chemicals. Herein, we introduce an acoustofluidic approach for microparticle and cell coating by implementing tilted-angle standing s...
