The electronic and magnetic properties of these structures were studied in detail.
Also the properties of the NiI2/ScTe2 structure under in-plane deformations were investigated.
This indicates the preservation of the magnetic structure of free-standing monolayers.

The XRD, SEM, FT-IR, BET and TGA were used to characterize the material structure and the adsorption property in CO2.
The synthesis of organics by CO2 is of importance for synthetic chemistry, utilization of carton and environmental protection.
As is shown by the Fig. 2, the composition and structure basically remain unchanged after being calcined under 300°C.
Above 500°C, the structure water starts to remove and form freedom-ends in order to achieve the purpose of activation.
The structure of sepiolite has been totally destroyed under 700°C.

Abstract.
Introduction Barium strontium titanate (Ba1-XSrXTiO3, hereafter referred to as BST), which has a typical perovskite-type structure, is a favorable electronic material due to its high dielectric constant and composition-dependent Curie temperature [1, 2].
