The Catalytic Efficiency of Au3+ metal ions and Au NPs on the Oxidation of Carbonyl Compounds by in situ Generated Na2FeO4 under Microwave Irradiation for Industrial Point of View

Anamika Srivastava; Anjali Yadav; Manish Srivastava

Volume 11, Issue 8 , August 2020, , Pages 1-5


  The catalytic activity of the Au NPs and Au 3+ metal ions used in the oxidation of carbonyl compounds by in situ generated Na2FeO4 from an industrial point of view. In the subsequent study used the chemical reduction and green method in favor of the fabrication of 30 to70nm in the size of Au NPs. Carbonyl ...  Read More

Phase selective growth of Ge nanocrystalline films by ionized cluster beam deposition technique and photo-oxidation study                           

S. Mukherjee; A. Pradhan; T. Maitra; A. Nayak; S. Bhunia

Volume 8, Issue 9 , September 2017, , Pages 891-896


  In this paper, we report the possibility of phase-selective growth of Ge nanocrystals by changing the kinetic energy of the clusters in an ionised cluster beam deposition system. Typically, the films are of mixed phase of normal cubic and high energy tetragonal structures, the relative proportion of ...  Read More

New polycrystalline MC-reinforced nickel-based superalloys for use at elevated temperatures (T > 1100°C)

Patrice Berthod

Volume 8, Issue 8 , August 2017, , Pages 866-872


  In some high temperature applications, there is a constant need of refractory alloys able to resist oxidation by hot gases, hot corrosion by various melts and creep deformation. The best superalloys are currently the g/g’ nickel-based single crystals but they cannot be exposed to 1200°C and ...  Read More

Tunneling Effect Of Photon-assisted AZO/SiOx/n-Si Heterojunction Device At Reverse Bias

H. W. Du; J. Yang; F. Xu; L. Zhao; Z. Q. Ma

Volume 7, Issue 5 , May 2016, , Pages 349-352


  Physical asymmetrical Metal / AZO / SiOx / n-Si / Metal devices in semiconductor-insulator-semiconductor (A-SIS) framework were investigated for their anormaly current-voltage characteristics under light irradiation. The devices showed a normal rectifying character in dark but manifested a peculiar current-voltage ...  Read More

Cerium(IV) Oxidations Of Sulfated Polysaccharides In Aqueous Perchlorate Solutions: A Kinetic And Mechanistic Approach

Ahmed Fawzy; Refat M. Hassan; Ismail Althagafi; Moataz Morad

Volume 7, Issue 5 , May 2016, , Pages 376-382


  The kinetics of oxidation of iota- and lambda-carrageenans as sulfated polysaccharides by cerium(IV) was studied spectrophotometrically in aqueous perchlorate solutions at a fixed ionic strength of 2.0 mol dm -3 and a temperature of 25 o C. The reactions showed a first order dependence on [Ce IV ], whereas ...  Read More

Cyclic Oxidation Behavior Of Bare And Cr3C2-25 (NiCr) Coated Super Alloy At Elevated Temperature

Sanjeet Kumar; Deepa Mudgal; Surendra Singh; Satya Prakash

Volume 4, Issue 10 , October 2013, , Pages 754-761


  High temperature oxidation is the main cause for the degradation of materials used at elevated temperature which is responsible for the major shut down of turbines, boilers and incinerators used in large units. An attempt has been made to use Cr3C2-25%NiCr coating deposited by D-gun technique on Superni ...  Read More
