Journal ArticleDOI
Synthesis and properties of α‐Fe2O3 nanorods
TL;DR: In this article, the reverse micelles method was used to synthesize α-Fe2O3 (hematite) nanorods using cetyltrimethyl ammonium bromide (CTAB) as surfactant and calcined at 300 °C.
Journal ArticleDOI
Characteristic enhancement of white LED lamp using low temperature co-fired ceramic-chip on board package
TL;DR: In this article, a low temperature co-fired ceramic-chip on board (LTCC-COB) package with improved thermal characteristics was proposed; no insulation layer exists between the LED chip and metal base.
Journal ArticleDOI
A study on composition, structure and optical properties of copper-poor CIGS thin film deposited by sequential sputtering of CuGa/In and In/(CuGa+In) precursors
TL;DR: In this paper, the elemental composition uniformity of CIGS-based solar cells was analyzed with energy dispersive spectroscopy (EDS), X-ray photo-electron spectrography (XPS) and secondary ion mass spectrograms (SIMS).
Journal ArticleDOI
Effect of substrate temperature on the structural properties of magnetron sputtered titanium nitride thin films with brush plated nickel interlayer on mild steel
TL;DR: In this paper, the phase of a thin film of titanium nitride (TiN) was identified with X-ray diffraction (XRD) analysis, and the results showed that the prominent peaks observed in the diffraction patterns correspond to the (1, 1, 1), (2, 0, 0) and (2, 2, 2) planes of TiN.
Journal ArticleDOI
Evaluation of corrosion and wear resistance titanium nitride (TiN) coated on mild steel (MS) with brush plated nickel interlayer
TL;DR: In this article, an additional nickel interlayer was brush plated on the steel substrates before TiN film formation to improve the corrosion resistance of TiN, which was found to have a weaker tendency towards corrosion and higher corrosion resistance in 3·5%NaCl than the bare MS substrate, Ni/MS and TiN/MS specimen.
