A novel lower cost mechanical solar absorber manufacturing method has been developed. C/Al2O3/Al surfaces have been characterized with optical and microstructural methods. The surface consists of thin inhomogeneous matrix containing carbon and Al2O3 on Al-substrate. Manufacturing of the surface can be done by single phase manual or mechanical grinding with a silicon carbide grinding pad. A sola...

Recent experiments have shown the viability of the metamaterial approach to dielectric response engineering for enhancing the transition temperature, Tc, of a superconductor. In this report, we demonstrate the use of Al2O3-coated aluminium nanoparticles to form the recently proposed epsilon near zero (ENZ) core-shell metamaterial superconductor with a Tc that is three times that of pure alumini...

High-resolution electron microscopy was employed to characterize the interface structure of a cast Al-Mg-Si-Bi-Pb aluminium(6262)-based composite reinforced by alpha alumina particles with a trace of beta alumina in order to investigate the behaviour of alloying elements in cast composites. Except for a few primary Mg2Si particles, few reaction products were detected at the interface of Al/alph...

The attention of researches in convective heat transfer by suspended nanoparticles base fluids has grown lately to promote uncommon techniques for enhancing the thermal performance fluids. In this study, stability period and properties aluminium oxide (Al2O3), silicon dioxide (SiO2) Al2O3–SiO2 hybrid were investigated at volume concentration 0.1vol.% dispersed Distilled Water (DW) as a fluid. Fo...

This work presents vertical flash memory devices with protein-assembled PbSe nanocrystals as a floating gate and Al2O3 as a control oxide. The advantage of a vertical structure is that it improves cell density. Protein assembly improves uniformity of nanocrystals, which reduces threshold voltage variation among devices. The introduction of Al2O3 as a control oxide provided lower voltage/faster ...

Hierarchically structured aluminium oxide was hydrothermally synthesized with carbamide as a precipitator. Raman spectroscopy, SEM spectroscopy, and X-ray phase analysis were used to investigate morphology and parameters of porously structured aluminium oxide as influenced upon by concentration of reactive solution, excessive portions of precipitator, and the counterion type. Differing mechanis...
