| 1 | Electrochemical Study of Diffusion Bonded Joints between Micro-duplex Stainless Steel and Ti6A14V Alloy显示文摘In the present study,corrosion behavior of diffusion bonded joints formed between micro-duplex stainless steel(MDSS) and Ti6AI4V alloy(TiA)(at 900 ℃ for 60 min under 4 MPa uniaxial pressure in vacuum) was investigated in 1 mol/L HCI and 1 mol/L NaOH solutions using various electrochemical measurements such as open circuit potential(OCP),electrochemical impedance spectroscopy(EIS) and potentiodynamic polarization(PD).For comparison,corrosion behavior of base metals(MDSS and TiA) was also evaluated.Bonded joint was characterized by light optical microscopy and scanning electron microscopy using backscattered electron mode.The layer wise σ phase and λ + FeTi phase mixture has been observed at the bond interface and the bond tensile strength and shear strength were ~556.4 MPa and ~420.2 MPa,respectively. | Shaily M.Bhola Sukumar Kundu Rahul Bhola Brajendra Mishra Subrata Chatterjee | 2014 | Journal of Materials Science & Technology2014，30，2： | 1 |
| 2 | A Brief Review on Fundamentals of Conductive Polymer(CPs)显示文摘Polymers are huge compounds made up of numerous monomers(repeated subunits).They have similar macro and micro properties,as well as electrical transport qualities,semiconductive capabilities,and optical features.With the advent of conductive polyacetylene,conductive polymers have gotten a lot of interest.These conductors have a wide range of electrical conductivity,which may be produced by doping,while being mechanically flexible and having a high thermal stability.Polymers may be created using a variety of methods,including chemical and electrochemical polymerization.With advancement in material stability and greater property control,an increasing variety of new applications are now being investigated. | Subhadeep Chakraborty Rahul Chatterjee Abhijit Bandyopadhyay | 2022 | Organic Polymer Material Research2022，4，1： | 0 |
| 3 | Competition between axial anomaly and ferromagnetic ordering in Bi_(2-x)Fe_(x)Se_(3-x)S_(x) topological insulator:A study of magnetic and magnetotransport properties显示文摘The topological insulators Bi_(2-x)Fe_(x)Se_(3-x)S_(x) have been investigated by the dc-magnetization,magnetotransport and angle resolved photoemission spectroscopy(ARPES)techniques.With doping of Fe and S,a negative giant magneto-resistance(MR)is observed for parallel electric and magnetic fields(H||E).The MR behavior at lower magnetic field can be explained with the semi-classical theory whereas the MR behavior at higher field has been attributed to the axial anomaly.Interestingly,the system reached to the quantum limit at low magnetic field(~4.5T).The magnetic ordering can be explained with the presence of both the RKKY(surface)and van-Vleck(bulk)interaction.The ARPES study reveals that a surface gap is suppressed when the magnetic ordering changes from ferromagnetic to anti-ferromagnetic ordering.The ARPES study and the appearance of quantum oscillations(SdH)in the resistivity pattern reveal that the topological surface property is preserved with the co-doping of Fe and S. | Rahul Singh Shiv Kumar A.Jain Mahima Singh Labanya Ghosh A.Singh Soma Banik A.Lakhani S.Patil E.F.Schwier K.Shimada S.M.Yusuf Sandip Chatterjee | 2022 | Journal of Materiomics2022，8，3： | 0 |
| 4 | Carbon and water footprints of major crop production in India显示文摘Scarcity of water and emission of greenhouse gases(GHGs)are the two key environmental issues affecting crop production in India.Reducing the carbon footprint(CF)and water footprint(WF)of crop production can help to mitigate the environmental hazards that stem from GHG emissions and water scarcity.The CFs and WFs of three major cereal crops,rice,wheat,and maize,were estimated for the year 2014 under the environmental conditions in India,based on national statistics and other data sources.Total CFs(TCFs)of rice,wheat,and maize in India were estimated to be 2.44,1.27,and 0.80 t CO_(2)equivalent ha-1,respectively,and product WFs for rice,wheat,and maize in India were 3.52,1.59,and 2.06 m3 kg^(-1),respectively.Blue WF was found to be the highest in West India for rice and in South India for both wheat and maize,with the highest irrigation water use in these regions.There was a positive correlation between TCF and total WF,and hence mitigation of both was possibly simultaneous in various regions in India.Potential measures for mitigating GHG emissions and optimizing water use for rice,wheat,and maize production in India are recommended in this paper. | Amaresh Kumar NAYAK Rahul TRIPATHI Manish DEBNATH Chinmaya Kumar SWAIN Biswaranjan DHAL Shanmugam VIJAYKUMAR Anshuman Debasis NAYAK Sangita MOHANTY Mohammad SHAHID Anjani KUMAR Manoj RAJAK Khitish Chandra MOHARANA Dibyendu CHATTERJEE Susmita MUNDA Pravat GURU Rubina KHANAM Banwari LAL Priyanka GAUTAM Suschismita PATTANAIK Arvind Kumar SHUKLA Nuala FITTON Pete SMITH Himanshu PATHAK | 2023 | Pedosphere2023，33，3： | 0 |
