چکیده

A series of Neodymium doped zinc-tellurite glasses incorporated with Ag 2 O chemical composition {[(TeO ) 0.70 (ZnO) 0.30 ] (1-X) Nd 3(X) } (0.99) (0.01), x = 0.01, 0.02, 0.03, 0.04 and 0.05, were synthesized by applying the melt-quenching technique. The FTIR analysis confirmed presence only two (2) active functional group (TeO 3 TeO 4 in wavenumber range 200–4000 cm −1 . spectra XRD glassy amorphous nature studied glasses. With addition more glass composition, both density molar volume increased. elastic moduli (longitudinal modulus, shear Young's modulus Bulk modulus) calculated from measured ultrasonic velocities obtained non-destructive testing performed at 5 MHz frequency. experimental results showed that rely upon system impact within network. increase is associated rigidity change structural network system. effects on Debye temperature, softening micro-hardness Poisson's ratio –ZnO–Ag also this work. acoustic impedance, as well coefficient thermal expansion glasses, calculated. physical properties' parameters suggest are strong enough for utilization fibre laser technology.

Elastic Properties and Fracture Analysis of Perfect and Boron-doped C2N-h2D Using Molecular Dynamics Simulation

   This paper explores the mechanical properties and fracture analysis of C2N-h2D single-layer sheets using classical molecular dynamics (MD) simulations. Simulations are carried out based on the Tersoff potential energy function within Nose-Hoover thermostat algorithm at the constant room temperature in a canonical ensemble. The influences of boron (B) doping on the mechanical properties, ...

Tetracene Based OTFT with Nd2O3-dielectric Layer

Tetracene thin film transistors with rare earth oxide (Nd2O3) as gate dielectric is reported in this work. Rare earth oxide with high dielectric constant and low leakage current improve the performance of the organic thin film transistors (OTFTs). The fabricated tetracene OTFTs have shown good output characteristics with mobility 0.93x10 cm/V.s, ON-OFF ratio 3.3x10, sub-threshold swing 0.06 V/d...

HIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS

Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...

Hydrogenation Properties of TiFe Doped with Zirconium

The goal of this study was to optimize the activation behaviour of hydrogen storage alloy TiFe. We found that the addition of a small amount of Zr in TiFe alloy greatly reduces the hydrogenation activation time. Two different procedural synthesis methods were applied: co-melt, where the TiFe was melted and afterward re-melted with the addition of Zr, and single-melt, where Ti, Fe and Zr were me...
