Title: Understanding the Effect of Uniaxial Tensile Strain on the Early Stages of Sensitizationin AISI 304 Austenitic Stainless Steel

Author(s): P S Chowdhury, S K Guchhait, P K Mitra, P Mukherjee, N Gayathri and M K Mitra.

Journal Name: Materials Chemistry and Physics Volume: 155; Year: 2015; Page: 217-222; ISSN: 0254-0584

Abstract: In the present study, an attempt has been made to understand the effect of different competing mechanisms controlling the overall degree of sensitization (DOS) of deformed austenitic stainless steel at the early stage of sensitization. The Double Loop Electrochemical Potentiokinetic Reactivation (DL-EPR) studies were performed to characterize the Degree of Sensitization (DOS) as a function of both pre-defined strain and sensitization temperature. X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to explain the phenomena qualitatively. A non-monotonous behaviour in the variation of DOS has been observed with deformation and sensitization temperature. The presence of Deformation Induced Martensites (DIM) and their transformation into tempered martensites (α + M23C6) at higher temperatures was found to play major roles in controlling the overall sensitization and desensitization processes.

Title: Soft sets combined with interval valued intuitionistic fuzzy sets of type-2 and rough sets.

Author(s): Anjan Mukherjee, Abhijit Saha, Ajoykanti Das.

Journal Name: New Trends in Mathematical Sciences Volume: 3; Year: 2015; Issue: 2; Page: 199-218; ISSN: 2147 – 5520

Abstract: Fuzzy set theory, rough set theory and soft set theory are all mathematical tools dealing with uncertainties. The concept of type-2 fuzzy sets was introduced by Zadeh in 1975 which was extended to interval valued intuitionistic fuzzy sets of type-2 by the authors. This paper is devoted to the discussions of the combinations of interval valued intuitionistic sets of type-2, soft sets and rough sets. Three different types of new hybrid models, namely-interval valued intuitionistic fuzzy soft sets of type-2, soft rough interval valued intuitionistic fuzzy sets of type-2 and soft interval valued intuitionistic fuzzy rough sets of type-2 are proposed and their properties are derived.

Title: Solid-state transformation of single precursor vanadium complex nanostructures to V2O5 andVO2: catalytic activity of V2O5 for oxidative coupling of 2-naphthol.

Author(s): Mukul Pradhan,Anindita Roy,Arun Kumar Sinha,Ramkrishna Sahoo, DibakarDeband Tarasankar Pal.

Journal Name: Dalton Transactions Volume: 44; Year: 2015; Issue: 4; Page: 1889-1899; ISSN: 1477-9226

Abstract: A vanadium complex, [(C5H5N)2V2O3-H2O], of different morphologies has been obtained via a modified hydrothermal procedure using pyridine and VOSO4 salt as the starting material. The evolved [(C5H5N)2V2O3-H2O] nanobelts are of 50–200 nm in width and of a length up to several millimeters. At higher temperatures (600 °C), the solid [(C5H5N)2V2O3-H2O] nanostructures are converted to vanadium pentoxide (V2O5) and vanadium dioxide (VO2) when heated in air and nitrogen atmosphere, respectively. During growth, the mechanism of the evolution of octahedra, truncated octahedra, and hollow truncated octahedra of [(C5H5N)2V2O3-H2O] are reported for the first time. These types of well-structured morphology are also isolated while V2O5 and VO2 are evolved. The as-grown belt-like and octahedral morphologies of [(C5H5N)2V2O3-H2O] are retained during the solid-state transformation, suggesting a route to evolve crystalline nanomaterials. Again, the morphological evolution of the [(C5H5N)2V2O3-H2O] nanostructures has been examined to be pyridine and precursor vanadyl sulfate (VS) concentration dependent. Thus, we are able to isolate truncated octahedra as an intermediate during the formation of [(C5H5N)2V2O3-H2O] nanobelts and nanoflowers with a high pyridine (Py) concentration. Interestingly, longer reaction times successively featured the transformation of truncated octahedra into nanobelts. Nanobelt evolution is not observed at low pyridine concentrations. However, the formation of octahedral morphology takes place at low pyridine concentration. All of the nanostructures were critically examined and characterized thoroughly by various physical techniques to ascertain their purity, structure and composition. An interesting, thermodynamically stable, single crystalline product from DMF soluble [(C5H5N)2V2O3-H2O] has been characterized, which indirectly supports the composition of [(C5H5N)2V2O3-H2O]. Selectively, vanadium pentoxide nanobelts have been found to be an efficient catalyst for the oxidative coupling of 2-naphthol to binaphthols under a molecular oxygen atmosphere.

Title: Synthesis and Structure of a Series of V-M (M = Li, Na & K) Heterobimetallic Complexes Using Metalloligand (VO2L): Discrete Mononuclear to 3D Coordination Polymer

Author(s): A. K. De, D. Deb, A. Koch and M. Chakraborty.

Proceedings Name: Proceedings of REACH-2015: An International Symposium on Recent Advances in Chemistry, Organized by UGC-Centre for Advance Studies in Chemistry North Eastern Hill University Shillong-793022, India

Abstract: Synthesis of heterobimetallic and multimetallic complexes of vanadium could be obtained by several routes. One of the best routes to synthesize such complexes is the reaction of a preformed metal complex having free Lewis basic site(s), known as metalloligand, with another Lewis acidic metal(s) [1, 2]. Here vanadium metalloligand is used to synthesize heterometallic and multimetallic complexes. All these studies may be very significant with regards to furthering our basic understanding of the structural topologies of heterometallic, as well as providing methods to enable a systematic approach to be used during synthesis of polymeric network. The major goal of this research work is to study the binding properties of the vanadium metalloligand with different alkali metal ions. We have synthesized monomeric, dimeric and polymeric vanadium complexes, [Li(H2O)3VO2L], [{Na(H2O)3(VO2)L}2.H2O] and [K(H2O)3VO2L]n [(HL) respectively using vanadium metalloligand [VO2L]- by the use of organic ligand, salicylaldehyde isonicotinoylhydrazone (HL) having oxygen and nitrogen donors.

Author(s) : Kisor Ray, Santanu Ghosh, Mridul Das, Bhaswati Ray

Journal Name: International Journal of Computer Trends and Technology, Volume-21 Number-2,2015, ISSN 2231-2803

Abstract: The modern treatment of any disease is heavily dependent on the medical diagnosis. Clinical data obtained through the diagnostics tests need to be collected and entered into the computer database in order to make a clinical data repository. In most of the cases, manual entry is an absolute necessity. However, manual entry can cause errors also, leading to wrong diagnosis. This paper explains how data could be entered free of error to reduce the chances of wrong diagnosis by designing and implementation of a simple database driven application.

Title :Design and Implementation of a GUI based Offline GIFT Tool to exchange data  between different systems Author(s) : Kisor Ray, Partha Pratim deb

Journal Name: International Journal of Computer Applications, Volume 114, No.3, March 2015, ISSN 09758887 Subjects: Computers and Society (cs.CY) Abstract: Multiple Choice Questions or MCQs are very important for e-learning. Many MCQ Tools allow us to generate MCQs very easily. However, in most of the cases they are not portable. That means MCQs generated for one system cannot be used for other unless a common format is used. So, collaboration and/or up gradation becomes a time consuming tedious task. In this paper, we will examine how tool could be designed which can produce portable MCQs and that too generating in the laptop and/or desktop without any need for going online.
