Advanced Science, EarlyView.An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

Adsorption isotherm on ferrites
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1994 Tlıe corrosion behaviour of the prepared Materials was studied by mcans of weight-loss techniquc in stagnant solution of (0.01 M) sulphuric acid in presence of thiourea as an inhibitor. Higher concentration of thiourea reduces the corrosion rate of thc samples and proteetion effi- cicncy of thiourea was found to be 80 % for ferrites Proteetion is ...

Surface‐Spin‐Induced Magnetic Loss Enhancement in Ultralight Electromagnetic Absorbers
Advanced Science, EarlyView.Fe3O4 nanoparticles with different hollow rates were synthesized to demonstrate the key role of surface moment in magnetic loss process. Using the same volume filling ratio, the 54.1% hollow Fe3O4 absorber represents about 20% enhancement in the imaginary part (μ'') than solid particles due to the coexisting magnetic resonance of inside and outside ...
