Nowadays, many researchers are focused on finding a solution to the problem of global warming. Carbon dioxide is considered be responsible for “greenhouse” effect. The largest emission industrial CO2 comes from fossil fuel combustion, which makes power plants perfect point source targets immediate reductions. A state-of-the-art method capturing carbon chemical absorption using an aqueous alkano...

Ag-28.1 wt. % Cu eutectic alloy solidifies in the form of eutectic dendrite at undercooling above 76 K. The remelting and ripening of the original lamellar eutectics result in the formation of the anomalous eutectics in the final microstructure. The addition of the third element Sb (0.5 and 1 wt. %) does not change the growth mode, but enlarges the volume fraction of anomalous eutectics because...

Laser remelting has been performed on Ni-30 wt.% Sn hypoeutectic alloy. An anomalous eutectic formed at the bottom of the molten pool when the sample was remelted thoroughly. 3D morphologies of the α-Ni and Ni3Sn phases in the anomalous eutectic region were obtained and investigated using serial sectioning reconstruction technology. It is found that the Ni3Sn phase has a continuous interconnect...
