Comparation in microstructure evolutions between casted and sintered Co-Cr-Ni alloys

Cailiao gongcheng
Cobalt-chromium-nickel (Co-Cr-Ni) alloys were prepared by two techniques of the sub-rapid solidification (SRS) and vacuum sintering (VS). The effects of the preparation processing and the content of Cr, Ni on the microstructure evolution were ...

Heterophase fcc‐hcp‐fcc High‐Entropy Alloy Nanomaterials with Tailored Electron Divergence for Selective Ammonia Electrosynthesis

Advanced Materials, EarlyView.
Heterophase fcc‐hcp‐fcc RuFeMMnMo (M═CoNi, Co, and Ni) high‐entropy alloy nanomaterials have been successfully synthesized using a one‐pot approach. The highly random distribution of multiple metal components and the tunable diversity of metal atomic arrangements can be realized simultaneously. By combining metals with different work functions, fcc‐hcp‐

Coexistence of fcc and hcp phases of C60

Chemical physics letters, 1993
The unusual features observed in TEM images of solution-grown fcc C60 crystallites (Z.G. Li and P.J. Fagan, Chem. Phys. Letters 194 (1992) 461) can be explained either by assuming the presence of a bct (body centered tetragonal) phase, or by identifying the bright spots with extremes of the projected charge density, suggesting a hcp phase.

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Advanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.
