Abstract Synthesized these novel structures PPy-MWCNTs/TiO2/Al2O3/p-Si and PPy-MWCNTs/TiO2/Al2O3/n- for using in manufactures diodes, sensor, supercapacitors, electronic devices. The effect of silicon substrate type on electrical dielectric parameters such as constant ɛ`, loss tangent tanδ, Cole –Cole diagram, the width depletion layer (Wd), barrier height (Φb), density state surface (NSS) seri...

The effect of non-magnetic oxides such as Al2O3, TiO2 and ZnO on the microwave absorption properties magnetoplumbite barium hexaferrite (BaFe11.8Co0.2O19) is analyzed. Barium nanoparticles are synthesized through sol-gel auto-combustion method. BaFe11.8Co0.2O19-Al2O3, BaFe11.8Co0.2O19-TiO2 BaFe11.8Co0.2O19-ZnO composites in a 1:1 ratio mechanical mixing heat treatment. epoxy fabricated with 50%...

Bu çalışmada Co0,92-xMn0,08Ptx/TiO2 ve Co0,92-xMn0,08Ptx/Al2O3 nano katalizörleri sentezlenmiştir. Destekli katalizörlerin üretilmesinde impregnasyon tekniği kullanılmıştır. Katalizörlerin hidroliz yöntemi ile NaBH4’ü parçalararak yüksek hızda hidrojen üretme yetenekleri belirlenmiştir. özelliklerinin belirlenmesi için geçirimli taramalı electron mikroskopları (TEM SEM), X-ışını difraktometresi...

(3-(tert-butylperoxy)propyl) trimethoxysilane (TBPT), is a tailor-made new style silane coupling agent with peroxide group, which have ability of initiating polymerization. This study used TBPT to generate free radical, and initiated the polymerization of acrylonitrile (AN), thereby forming polyacrylonitrile (PAN) in two approaches, thermal initiation system and redox initiation system. Meanwhi...

Polymeric nanocomposites are an emerging research topic, as they improve fiber-reinforced composites’ thermo-mechanical and tribological properties. Nanomaterials electrical thermal conductivity provide excellent wear friction resistance to the polymer matrix material. In this work, a systematic study was carried out examine tensile hardness properties of carbon fiber epoxy composite comprising...

In the present research work physical, mechanical and tribological behavior of Aluminum (Al) alloy LM13 reinforced with Nano-sized Titanium Dioxide (TiO2) particulates were fabricated, mechanical and tribological properties were investigated. The amount of nano TiO2 particulates in the composite was added from 0.5% to 2% in 0.5 weight percent (wt %) increments. The Al-LM13-TiO2 Metal Matrix Com...

BACKGROUND Un-doped and N-doped TiO2 nano-particles with different nitrogen contents were successfully synthesized by a simple sol-gel method, and were characterized by X-ray diffraction, field emission scanning electron microscopy, Energy dispersive X-ray analysis and UV-visible diffuse reflectance spectra techniques. Then enhancement of sonocatalytic degradation of humic acid by un-doped and ...
