The solid-state transformation phenomena of spinodal decomposition and nucleation growth are presented as tools to create nanostructured thermoelectric materials with very low thermal conductivity greatly enhanced figure merit. systems (PbTe)(1-x)(PbS)(x) (Pb(0.95)Sn(0.05)Te)(1-x)(PbS)(x) not solid solutions but phase separate into PbTe-rich PbS-rich regions produce coherent nanoscale heterogeneities that severely depress the lattice conductivity. For x > approximately 0.03 ordered on three...
Abstract In the present study, different series of high‐density polyethylene (HDPE) nanocomposites were prepared by melt mixing on a Haake‐Buchler Reomixer, containing 2.5 wt % multiwall carbon nanotubes, pristine and modified montmorillonite, surface‐treated ‐untreated SiO 2 nanoparticles. From transmission electron micrographs, it was found that beyond fine dispersion nanoparticles into HDPE matrix, there are also some aggregates easily discriminated. As result, decrease in tensile impact...
We have performed a comparative investigation of the Ag1−xPb18MTe20 (M = Bi, Sb) (x 0, 0.14, 0.3) system to assess roles Sb and Bi on thermoelectric properties. Detailed charge transport data including electrical conductivity, Seebeck coefficient, Hall thermal conductivity are presented. Optical reflectivity support conclusions studies. For comparable nominal compositions, carrier concentrations lower in analogs mobilities higher. The coefficient decreases dramatically going from Bi. High...
The aim of this study was to investigate the possible reinforcement Nanodiamonds (ND) in a PMMA resin for fixed interim restorations. fracture toughness (KIc), impact strength and dynamic thermomechanical properties (Tg, E´, E´´, tanδ) series PMMA-ND nanocomposites with different amounts ND were evaluated. increased as percentage up 0.38% wt but greater amount induced decrease KIc. Impact Young's modulus also by increasing nanoparticles content, indicating reinforcing effect ND. Dynamic...
The thermal behavior of a well known bioactive glass, Bioglass®, is examined beyond its melting temperature as the crystallization and sintering glass may influence bioactivity cellular reactions. Differential analysis (DTA) followed by thermogravimetric (TGA) was used to determine transition (Tg), (Tc), (Tm) temperatures weight changes. characterization before after treatment at different characteristic accomplished with Fourier transform infrared spectroscopy (FTIR). All phases, during...
