Preparation of lanthanum zirconate nano-powders by Molten Salts method
, 2010 Pyrochlore La(2)Zr(2)O(7) nano-powders with cubic structure have been firstly prepared by Molten Salts method. These nano-powders were prepared at a relatively low temperature using La(NO(3))(3)center dot 6H(2)O and ZrOCl(2)center dot 8H(2)O as raw ...

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Hydrothermal synthesis of pure and Dy : BaTiO3 powders at 90 degrees C and their sintering behavior
, 1998 Sub-micron (150-200 nm), monodisperse and spherical powders of pure and Dy-doped (0.8 at%) BaTiO3 have been prepared by "hydrothermal synthesis" at 90 degrees C in an air atmosphere.

Development and evaluation of the powders mix low alloyed steel + SIC for selective laser melting
, 2022 reservedFor this work, the evaluation of the S2 tool steel + Silicon carbide (SiC) powders was provided in terms of the microstructural characterization after a thermal cycle and of the rheological properties of the mixtures. SiC powder was added at 5%,

Advanced Engineering Materials, EarlyView.Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
