Crystal Structure and Lattice Parameter Investigation of La3+ Substituted CeO2 in LaxCe1-xO2-X/2 Synthesized by Solid-State Method
Lanthanum (La) doped Ceria (CeO2) has attracted considerable interest as a candidate material for thermal barrier coating (TBC) because of its low thermal conductivity and potential capability to be operated above 1250°C. In this study, La2Ce2O7 powder was synthesized through the ball mill method. The crystal structure of La3+ su...
متن کاملa contrastive analysis of concord and head parameter in english and azerbaijani
این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
15 صفحه اولParameter Study of GTN Model in a SLM Manufactured Lattice Structure under Compression by Using FEM
This study investigates the effect of material parameters of the Gurson-Tvergaard-Needleman (GTN) model on the failure prediction of cellular structures. The effect of elastic modulus, calibration parameter of GTN model, isotropic hardening, fracture strain, and strut diameter on the load-displacement curve of a lattice structure fabricated by Selective Laser Melting (SLM) has been studied by u...
متن کاملDirect synthesis and structure characterization of ultrafine CeO2 nanoparticles
A new method to directly synthesize single-crystalline CeO2 nanoparticles has been developed. The advantages of the method are rapid synthesis, at normal atmosphere, 100% productive ratio and low cost, with a great potential for scale-up. X-ray diffraction (XRD) spectra showed unusual peak width versus particle size, compared with Scherrer equation predictions. Scanning electron microscopy (SEM...
متن کاملSize and size distribution balance the dispersion of colloidal CeO2 nanoparticles in organic solvents.
Colloidal CeO2 nanoparticles (HNPs) stabilized with a decanoic fatty acid self-assembled monolayer (SAM) (decHNPs) showed very good dispersibility, i.e., perfect dispersion in cyclohexane up to 20 wt%. However, the HNPs stabilized with a dodecanoic acid SAM (dodHNPs) did not show good dispersion, i.e., at most 0.2 wt%. Interestingly, when we mixed equal portions of 5 wt% decHNPs in cyclohexane ...
