A novel control system for semibatch polymerization reactors based on nonlinear MPC is proposed that is aimed to deal with more than one control objective. Commonly, multi-objective control problem...
The preferential incorporation of Er3+ ions into the PbF2 nanocrystals during the ceraming process of oxyfluoride glass was analyzed using electron energy loss spectroscopy analysis. Concentrations...
We investigated the optical properties of La2Zr2O7 transparent ceramics and found that it showed abnormal partial dispersion. The origin of the abnormal partial dispersion was also investigated by ...
The crystalline structure refinement, chemical bond ionicity, and lattice energy were carried out for Zn(Ta1−xNbx)2O6 ceramics with tri-α-PbO2 structure to investigate the correlations between t...
Pronounced variations of the crystallite size of hafnia (HfO2) precipitates in silicon oxycarbide (SiOC)–HfO2 ceramic nanocomposites were studied by TEM upon annealing bulk samples at 1300°C for...
Single-phase metastable cubic spinel nickel manganite films, 0.5 ≤ Mn/(Mn+Ni) ≤ 0.8, were produced using chemical solution deposition. Of these, the sample with Mn/(Mn+Ni) = 0.80 showed the...
An ultra-broad working temperature dielectric material, BaTiO3–Na0.5Bi0.5TiO3–Nb2O5–MgO–Glass with Nd2O3 addition, was investigated for the first time. Microstructure and dielectric propert...
(Na0.5K0.5)NbO3 is doping with ZnO and CuO, respectively, (NKNZx and NKNCx, where x = 0–1 mol%) using a two-step calcination process (BO method). The X-ray diffraction profiles of NKNZx cerami...
This article is a report on the effect of Bi2O3 addition on microstructure and electrical properties of ZnO–V2O5–MnO2–Nb2O5 varistor ceramics. The average grain size increased from 5.6 to 7.2...
High resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD) techniques were used to examine the crystal structure of TiB ceramic powder synthesized by a Ti-Boronizing metho...
Micro/nano-structured Bi2Te3 bulk materials were prepared by cryogenic grinding followed by spark plasma sintering. The densification behavior, microstructure development, and thermal conductivity ...
Lead zirconate titanate (PZT) is one of the most commonly used piezoelectric ceramics. The major causes of its electrical fatigue are suggested to be domain pinning and cracking. However, their con...
Transparent AlON was pressurelessly sintered from powders synthesized by a two-step carbothermal nitridation method, using core-shell structured Al2O3/C mixture derived from the pyrolysis of an Al2...
LaMnO3 and (La,Sr)MnO3 were prepared as mesoporous powders using sol-gel methods that incorporated evaporation-induced self-assembly of surfactants as structure-directing agents. The precursor and ...
Previously a model was reported on the simulation of a SF6 plasma generated wettability gradient by considering only the diffusion of the reactive species in plasma. This study proposed a modified ...
