Dense W and W-Zr composites reinforced with Sc2O3 particles were produced through powder metallurgy and subsequent spark plasma sintering (SPS) at 1700 °C and 58 MPa. Results showed that the W-1vol.%Zr/2vol.%Sc2O3 composites exhibited optimal performance with the best relative density of up to 98.93% and high Vickers microhardness of approximately 583 Hv. The thermal conductivity of W-Zr/Sc2O3 ...

The development of alloyed quantum dot (QD) nanocrystals with attractive optical properties for a wide array of chemical and biological applications is a growing research field. In this work, size-tunable engineered band gap composition-dependent alloying and fixed-composition alloying were employed to fabricate new L-cysteine-capped alloyed quaternary CdZnTeS QDs exhibiting different internal ...

Molecular dynamics (MD) simulations using a first principles-based Embedded-atom-Method (EAM) potential are used to simulate the exothermic alloying reactions of a NiAl bilayer at 1500 K and 1100 K. Both microcanonical (NVE) and isoenthalpic (NPH) MD simulations are used to demonstrate the influence of pressure on atomic mixing and subsequent alloying reaction. The NVE simulations, in which the...

The composition, structure, and physicochemical properties of the surface near-surface layers silicon doped with low-energy (E 0 <5 keV) Ba + O 2 ions have been studied using a set photoelectron secondary electron spectroscopy methods. It has established that in process ion implantation, chemical bonds are formed between atoms alloying element matrix, width energy bands density electronic st...

Magnesium alloys have been identified as a new generation material of orthopaedic implants. In vitro setups mimicking physiological conditions are promising for material / degradation analysis prior to in vivo studies however the direct influence of cell on the degradation mechanism has never been investigated. For the first time, the direct, active, influence of human primary osteoblasts on ma...

One of the major issues required to be dealt with the casebased reasoning (CBR) is the challenge to meet to maintain and control the correctness and accuracy of the results expected to be produced against the proposed algorithm and methodology for the candidate CBR system. This paper introduces a computational model with the assistance of the concept of Regression fitting within the mathematica...
