A Comparison Study Between Two Hydrogen Sensors IJTSRD
In this research work, a comparison study has been carried out between Palladium Pd coated PMMA Poly Methyl Meth acryl ate optical sensor and Palladium thin films sensor that have been prepared on glass substrates. PMMA were sputter coated with Palladium using a sputter coating facility offered by the He riot Watt University, during sputter […]
Comparison Study Between Hydrogen Palladium Sensor and Hydrogen Manganese Dioxide Sensor IJTSRD
This research work oriented to compares between Palladium (Pd) thin films sensor that have been prepared on glass substrates and hydrogen sensor using optical ?ber, coated with Manganese dioxide (MnO2) nanostructures. Palladium thin films prepared by vaporization deposition technique with annealing temperature around 600C0. Where, manganese dioxide, prepared on Optical Multimode Fiber (MMF)of 125m in […]
Fe75-xCoxCu1Nb3Si15B6 Alloy with Rapid Stress Annealing IJTSRD
This Articler reports the effect of stress annealing treatment on the structural and magnetic properties of nanocrystalline Fe75-xCoxCu1Nb3Si15B6 & Co21Fe64-xNbxB15 alloys. Information obtained from magnetic measurements, X-ray diffraction measurements and Mössbauer spectroscopy reveal that for Fe75-xCoxCu1Nb3Si15B6 (x = 0, 2, 5) alloys the volume fraction of the Fe-Co nanograins and their grain diameter ranges between […]
Stress Annealed CoFeNbB Alloy : A Structural Study IJTSRD
Article presents the influence of Nb content on structural properties of stress annealed Co21Fe64-xNbxB15 (x = 3, 5, 7) alloys has been studied using differential scanning calorimetery, in-situ length change measurements during annealing and x-ray diffraction. Results show that, increase of Nb content in the alloy increases the stability of the alloy against crystallization and […]
