Efficient atrazine degradation through ZnFe2O4-catalyzed peroxymonosulphate activation
Characterization
In the XRD patterns of the prepared catalysts (Fig 1.), the peaks before and after the reaction matched well with those of cubic spinel ZnFe2O4 (JCPDS file No. 22–1012), confirming the presence of the ZnFe2O4 crystals. In Fig.

Geometry engineering of tunneling transistors in transition metal dichalcogenide nanoribbon heterojunctions
Double-barrier resonant tunneling transport for edge states
Prior to transport properties, we first explore the geometry effect on band structure of monolayer MoS2 nanoribbons. The geometry effect is mainly reflected in the nanoribbon edge due to…

Stacking polymorphism of PtSe2: its implication to layer-dependent metal-insulator transitions
Relaxed 1T and 2H monolayer structures
Firstly, we optimized the monolayer structures of 1T and 2H phases using DMC calculations. As depicted in Fig. 1a, d, the 1T and 2H phases are characterized by an octahedral and a trigonal structure,…
