Graphene was first obtained at the beginning of the 21st century, and since then various methods have been developed for its synthesis. This variety is explained by the natural layered structure of graphite. A large number of methods is based on the idea of separating graphite layers. They are considered relatively cheap, productive and available in almost all laboratories.
This study reports on the preparation of novel zinc/aluminium layered double hydroxide intercalated clopyralid (Zn/Al-LDH-CP) nanocomposites fabricated via co-precipitation. An expansion of the interlayer gallery of Zn/Al-LDH for the accommodation of clopyralid was observed from the powder X-ray diffraction (PXRD) pattern, confirming the occurrence of intercalation. The results from Fourier transform infrared and elemental analysis were consistent with those from PXRD, thus supporting the intercalation of clopyralid.
The EPR studies of electrical and magnetic properties of In4Se3 intercalated by copper are outlined in this article. Possibilities of using magnetic field sensors based on InSe structures for revealing the armour military vehicles are discussed. The impact of metal impurities on the layered structure of the semiconductor material as referred to the strong covalent bond within the layers as well as the weak van-der-Waals bond in the interlayer space is studied. EPR spectra for In4Se3 crystal with the impurities of Cu at room temperature are analyzed.
