Pressure-Dependent Structural and Optical Properties of CdSe
Abstract: AbstractThe structural and optical properties of Cadmium Selenide (CdSe) compound is investigated in zinc blende phases under 0–30 GPa pressure using Density Functional Theory (DFT) with generalized gradient approximation (GGA) functional embodied in Wien2k code. At zero pressure, lattice constant and bulk modulus are found to be in good agreement with experimental and other theoretical works. Other than zero pressure, there is reduction in volume of unit cell according to …

Structural and Electrical Characterization of Mn-Zn Substituted CaSr2: W-Type Hexaferrite
Abstract: AbstractIn the present investigation the samples with chemical composition CaSr2 (Mn-Zn)x/2Fe16- xO27 (x= 0.2, 0.4, 0.6, 0.8, 1.0) have been synthesized by using chemical co-precipitation method. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to study structure, lattice constants, crystallites size, x-ray density, bulk density, porosity and shape of ferrite powders. The prepared samples were found to have W-type hexagonal structure with the lattice parameters a= (5.77 Å–5.82 …

Investigation of the Pulse Shape and Amplitude of 4He Gas Scintillations Produced by a 5.5 MeV Alpha Particle Source
Abstract: AbstractScintillation light is normally produced when ionizing particles such as alpha particles deposit their energy as they travel through a scintillating material, which can be solid, liquid or gaseous (e.g. 4He). In this project we compared scintillations produced in 4He gas by alpha particles (from the decay of 241Am) to those produced in plastic scintillator by cosmic-ray muons. The properties of photomultiplier and Si photomultipliers as sensors of scintillation light …

Review of Reliability and Availability Evaluation of MPPGCL Sirmour Hydropower Station using Markov Modelling
Abstract: AbstractWater is one of the best renewable energy sources available, as we are almost totally dependent on the availability of depleting fossil fuels. Being more reliable and cost effective, hydel energy is attracting more investors and entrepreneurs for investing and establishing hydro power plant. Since maintenance and operation of a power plant is very challenging and complicated process, calculating and analysing its compatibility and reliability is very important. This paper …
