Chemical syntheses of homogenous solid solution alloy nanoparticles of noble metals require high temperature above 100 °C. Beside this, aqueous co-reduction methods lead to phase separation. In contrast, pulsed laser ablation in liquid (PLAL) allows synthesis of alloy nanoparticles with totally homogeneous ultrastructure in aqueous media at room temperature without reducing agents or organic li...

There is current interest in developing photoactive materials that deform on illumination. The strategy to develop new molecules solution, and then incorporate these the solid-state either by crystallization or inserting them into polymers. This letter shows kinetics nature of photo-induced phase transitions are profoundly different single (solution) solid state using a lattice spin model. In w...

Ceramics with starting compositions of P1−xGexNb9O25 (x = 0–1) were prepared by conventional solid-state reaction method. Crystal phases, microstructure and dielectric properties investigated. The formed crystal phases for the x 0 1 identified as PNb9O25 GeNb18O47, respectively, a continuous solid solution was < 1. As increased, decrease grain size, denser an increase constant observed. composi...

A two-dimensional phase-field method was developed that allowed us to observe the evolution of the composition field and the microstructure of lamellar eutectics caused by variations in the freezing rate. Solid-phase nucleation, lamella termination, and migration of the three-phase junction were studied to elucidate the role of each in microstructure changes. This evolution is often complex due...

The synthesis of (Ba0.99Ca0.01)(Zr0.2Ti0.8)O3 (BCZT) and doped (Ba0.99Ca0.01)(Zr0.2Ti0.8-xMnx)O3 (BCZT-xMn) ceramics was successfully carried out by the solid-state method. doping effect is followed X-ray powder diffraction, scanning electron microscopy (SEM), dielectric conductivity measurements. Indeed, diffraction measurements show crystalline structure ceramics. SEM images indicate on studi...

the microstructure of hp stainless steel in aged and aged + solution annealed conditions and solutionized alloy 800 was characterized by optical microscopy, scanning electron microscopy (sem), and transmission electron microscopy (tem) equipped by eds. all phases present in the above condition were described. the effects of solution annealing heat treatment temperature on the microstructure, te...

Ta1-xZrxN thin films were deposited by reactive magnetron sputtering aiming to investigate the influence of zirconium addition on microstructure, hardness and high temperature oxidation resistance coatings. GAXRD showed that all maintained ZrN crystalline structure, forming a TaZrN solid solution. Zr incorporation did not alter values coatings, however, promoted significant improvements in when...
