Two-dimensional layered semiconductors have attracted intense interest in recent years. The van der Waals coupling between the layers tolerates stacking various materials and establishing heterostructures with new charac...

Dynamic manipulation of terahertz (THz) beams plays an important role in THz application systems. The PB metasurface provides an effective scheme for space separation and deflection of the spin beam. However, mirror symm...

Assessment of the process of bio-economic transformation of socioeconomic systems and its consequences in various countries, and in Ukraine in particular, is quite problematic since the existing methodology of the State ...

A novel main-chain polyurethane initiator was obtained by the ternary polyaddition of mesogenic diol, aliphatic azodiol (initiator component), and diisocyanate. The mesogenic diol, in which 6-hydroxyhexyloxy groups linke...

Metalenses have potential to replace various bulky conventional optical elements with ultrathin nanostructure arrays. In particular, active metalenses with reconfigurable focusing capability have attracted considerable i...
