The effect of Fe substitution on the phase transformation and magnetic properties of Mn2NiGa has been studied. A single bcc phase was obtained in Mn2−xFexNiGa (x=0–0.6). With the substitution of Fe for Mn, the lattice constant decreases gradually. The martensitic transformation can be observed when x=0–0.3. Both the m…
<JATS1:p>The basic principles of the flat-pattern method are the foundation of producing effective apparel designs. Principles of Flat-Pattern Design, 4th Edition, maintains its simple and straightforward presentation of flat-patternmaking principles which is proven to be less intimidating for beginning students. Numb…
We introduced co-dopants into well-known orthosilicate phosphors such as and . co-doping had a positive influence on the overall photoluminescence (PL) intensity of , and , . In the absence of barium incorporation, co-doping induced phase transformation of the host from the β to the α' phase, such that the peak locati…
A natural biofoam extracted from the petiole of the buriti palm tree has shown values of density and mechanical strength with potential for uses in engineering applications such as automobile interior parts and floating components. Moreover, foams can also be used as insulating materials in packing and building panels…
Photoluminescence and coloring properties of -doped were investigated for developing an inorganic luminescent pigment. Powder samples were synthesized by three kinds of methods, namely, a simple solid-state reaction, a stepwise solid-state reaction, and a precipitation. obtained by the simple solid-state reaction show…
A variety of Schiff base ligands have been synthesized in an effort to study the coordination chemistry of these ligands when reacted with various metal salts. By varying the structural features of the ligand as well as the synthetic route used to make the corresponding metal complexes, a number of different structura…
Electrochemical double-layer capacitor (also called supercapacitor) is an electrochemical energy storage device with a high power density, which could be used in application such as pulse power devices or electric vehicles. The paper describes construction of an electrochemical double-layer capacitor that consists of…
In recent years polymer science has been developed enormously. Researchers have made some significant discoveries and advancements in this field. All these things have lead to a new era of polymer science especially biodegradable polymers. Today a number of biopolymers are known and used for different purposes in biom…

Substitution of La by Sr in the 25% Ni doped charge transfer insulator LaFeO3 leads to structural changes that inflect the electrical conductivity, which is caused by small polaron hopping via charge transfer and exchange interactions. The substitution forms electron holes and causes a structural transition from ortho…
Doping and temperature dependent studies of optical phonon modes in Fe-122 pnictides are performed using Raman scattering experiments and compared with model calculations to elucidate the role of electron-phonon and spin-phonon interaction in this family of compounds. The frequency and linewidth of the B(1g) mode at a…

The effect of organo-montmorillonite (OMMT) on the properties of acrylonitrile butadiene rubber/polyvinyl chloride/OMMT (NBR/PVC/OMMT) nanocomposites is studied. Four different types of organo-modified OMMT were examined in NBR/PVC blend systems and an optimum type of OMMT (FMR11) was found by characterizing the mecha…
In recent years, compact spinning technology, recognised as a revolution in ring spinning, has been successfully used in the production of mono-fibre yarns and blended yarns. Under standing the radial distribution of fibres in compact-spun flax-cotton blended yarn is of im portance for improvement in the performance o…
The present investigation deals with the dissolution behavior of pure Copper and its one of the alloy (Cu-27Zn Brass) in Natural Sea water environment at various time, temperature and various concentration of Vitis vinifera seed and skin extract. The inhibition efficiency is markedly higher in Natural sea water with a…
In this study, mechanical and performance analyses of woven fabrics were carried out using objective evaluation techniques. The KES-FB Auto system, the FAST system and Cusick’s Drape Meter were used to evaluate the mechanical properties of the fabrics. The shear, bending, extension, and compression parameters were mea…
We examine the evolution (‘healing’) of the interface between two polymer films at various temperatures below the glass transition temperature, Tg. Specifically, neutron reflectometry is used to study the relaxation of the interface between both unentangled and entangled deuterated polystyrene (d-PS) and hydrogenated…
