Characterization and Electrochemical Behaviour of Nanoscale Hydrotalcite-Like Compounds toward the Reduction of Nitrate

Nanomaterials, 2020
In this research, nano Cu/Al–HTLCs, Co/Al–HTLCs and Cu/Co/Al–HTLCs were synthesized, characterized, and tested in electrolytic reduction nitrate. Experimental results showed that Cu/Al–HTLCs were less stable than Co/Al–HTLCs due to the Jahn–Teller effect.

Magnetic Properties and Microstructure of Ce-Cu-Al Low Melting Alloy Bonding Sm₂Fe₁₇N₃ Magnet Fabricated by the Hot-Pressing Method

Magnetochemistry, 2022
Sm2Fe17N3 compounds, having excellent intrinsic magnetic properties, are prone to decomposition at high temperatures; thus, a low melting point metal binder is the key to prepare high performance bulk magnets at low temperatures. In this paper, a new low

A first-principles analysis of ballistic conductance, grain boundary scattering and vertical resistance in aluminum interconnects

AIP Advances, 2018
We present an ab initio evaluation of electron scattering mechanisms in Al interconnects from a back-end-of-line (BEOL) perspective. We consider the ballistic conductance as a function of nanowire size, as well as the impact of surface oxidation on ...
