On the Formation of Earth and Celestial Bodies Open
Understanding the formation of the solar system can provide a simplified look at the universe at large. This is because we have a lot of evidence about the formation of our solar system, and because the universe is homogeneous on a large s…

Influence of Gd content on structural, electronic, thermoelectric, and optical properties of WO<sub>3</sub> Open
WO 3 -based semiconductor materials are optimistic competitors for modern electronic devices because of their outstanding electronic and optical properties. Simulations on pure and Gd-doped WO 3 compositions were executed using Tran and Bl…

Effect of Cu Cladding on the Mechanical Properties of Iron Sheath Material in the Drawing of Superconducting MgB2 Wires Open
In the present study, a novel choice of sheath materials for drawing long superconducting MgB2 wire by using the powder-in-tube technique (PIT) is reported. This would eliminate the need for an intermediate strain-relieving annealing proce…

Uniform Dispersion and Exfoliation of Multi-Walled Carbon Nanotubes in CNT-MgB2 Superconductor Composites Using Surfactants Open
We developed a novel yet commercially viable strategy of synthesizing superior high-TC superconducting composites by dispersing fully exfoliated carbon nanotubes (CNTs) uniformly throughout the grain of CNT-MgB2 composites. First, we optim…

Correlation between grain connectivity, packing density, and critical current density in MgB2 synthesized by in situ/ex situ combination technique. Open
Undoped magnesium diboride (MgB2) bulks were systematically synthesized by using in situ/ex situ combination method. Herein, using ex situ powder could act as a seed material to further improve adhesion on interface with MgB2 formed by in …

Synthesis and Characterization of BaTiO3/Polypyrrole Composites with Exceptional Dielectric Behaviour Open
Higher concentrations of ceramic fillers induce brittleness in the ceramic/polymer hybrids which restrict their applications to limited fields especially when such hybrids are prepared for their use as dielectrics. We have synthesized and …

Durability and Mechanical Performance of PMMA/Stone Sludge Nanocomposites for Acrylic Solid Surface Applications Open
Acrylic solid surface sheets were prepared by mixing different kinds of stone sludge fillers (SSF) in Poly (methyl methacrylate) (PMMA) nanocomposites. PMMA nanocomposite syrups were made using free radical polymerization of methylmethacry…

Two-photon absorption of Tl<sub>1-x</sub>In<sub>1-x</sub>Sn<sub>x</sub>Se<sub>2</sub>nanocrystallites Open
Novel materials for the infrared two-photon absorption — Tl1-xIn1-xSnxSe2 single crystals (x = 0.1,0.2) were grown. Two-photon absorption (TPA) was studied at CO2 laser wave-length 9.4μm with pulse duration 1μs. The studies were performed …
