In the present work, four polymeric nanocomposite PNC coatings were prepared with different concentrations of yttrium aluminum garnet nanoparticles YAG-NPs in polyvinyl butyral PVB matrix. The corrosion protection of the PNC coatings applied on the carbon steel surface was investigated in 1.0 M HCl solution by electrochemical impedance spectroscopy EIS. The YAG-NPs were synthesized by pulse ele...

A significant obstacle in the development of YAG:Ce nanoparticles as light converters in white LEDs and as biological labels is associated with the difficulty of finding preparative conditions that allow simultaneous control of structure, particle size and size distribution, while maintaining the optical properties of bulk samples. Preparation conditions frequently involve high-temperature trea...

Yttrium aluminum oxide Y3Al5O12 (YAG:Ce) nanoparticles were prepared by laser ablation in liquid, and the photoluminescence (PL) properties of the nanoparticles were investigated. A pellet of YAG:Ce synthesized by co-precipitation in deionized water was irradiated with a focused laser beam to obtain a solution containing dispersed nanoparticles. The compositions and morphologies of the nanopart...

Here, we demonstrate the fabrication of a stable polymer optical fibre doped with 1,4-bis (2-methylstyryl) benzene (Bis-MSB) that contains silver nanoparticles. Spherical nanoparticles approximate size 15 nm were fabricated using nanosecond laser ablation. A Q-switched Nd: YAG operating at 355 was used to pump fiber in order analyse its emission characteristics. The pulse energy (PPE) dependent...

PURPOSE Optic coherence tomography (OCT) evaluation of the choroid, retina, and retinal nerve fiber layer after uncomplicated yttrium-aluminum-garnet (YAG) laser capsulotomy. METHODS OCT analysis of retinal and choroidal structures was performed in 28 eyes of 28 patients following routine examinations before and 24 h, 72 h, 2 weeks, 4 weeks, and 12 weeks after YAG laser capsulotomy. Data were...

In the present work, Laser Induced Breakdown Spectroscopy (LIBS) has been utilized to investigate two forms of aluminum samples, namely Al in form nanoparticles (NPs) and a bulk (pellet). The target was irradiated by pulsed Nd-YAG laser with wavelength 1064 nm produce plasma. plasm spectrum is analyzed range between 250 700 nm. Some plasma parameters were calculated, including electron temperat...

This paper describes a new multilayer TBC that incorporates a 10 μm-thick oxygen barrier layer of yttrium–aluminum garnet (YAG) into a typical YSZ TBC system. The thermal conductivity of as-sprayed YAG/YSZ coatings was reduced due to excessive porosity and amorphous areas in the YAG layer. After long-term heat treatments, the conductivity of the multilayer was unaffected by the presence of YAG....

STUDY OBJECTIVE To evaluate the cost effectiveness of the Nd-YAG laser and bronchoscopic electrocautery for palliation in patients with symptomatic tumor obstruction. DESIGN A retrospective study. SETTING Bronchoscopy unit of a university hospital. PATIENTS AND INTERVENTION Thirty-one consecutive patients with inoperable non-small cell lung cancer and symptomatic intraluminal tumor underw...

Yttrium aluminium garnet (YAG) is a promising topcoat material for thermal barrier coatings due to its high temperature stability and better CMAS (calcium-magnesium-alumino-silicate) resistance. YAG topcoats were deposited by suspension solution precursor high-velocity oxy-fuel (HVOF) spray. The relationships between processing, microstructure final properties studied through range of character...
