COMMON TRAITS AND DIFFERENCES IN THE VERBALIZATION OF SUPERSTRUCTURES IN MEDIA GENRES [PDF]

open access: yesStudies in Linguistics, Culture, and FLT, 2018
The article deals with the semantic structure (superstructure) of two media genres: the radio discussion and the TV news. There have been revealed the components of the prototypical superstructure, which characterize the genre in different languages ...

Domain variance and superstructure across the antiferroelectric/ferroelectric phase boundary in Pb1−1.5xLax(Zr0.9TiM0.1)O3 [PDF]

open access: yes, 2003
Transmission electron microscopy, x-ray diffraction, relative permittivity as a function of temperature, and polarization versus field loops were used to study the antiferroelectric/ferroelectric (AFE/FE) phase boundary in Pb1−1.5xLaxZr0.9Ti0.1O3 ...

The controllable synthesis of urchin-shaped hierarchical superstructure MOFs with high catalytic activity and stability

open access: yes, 2021
A novel dissolution–crystallization-attachment strategy was developed to synthesize urchin-shaped superstructure metal–organic frameworks (MOFs) with self-assembled one-dimensional nanorods. The superstructure MOFs not only inherited the high activity of

SYNTHESIS OF THE THERMALLY COUPLED DISTILLATION SEQUENCES

open access: yesТонкие химические технологии, 2017
Approaching a hypothetical thermodynamically reversible process is one of the main directions of energy saving in distillation. In practice, this is achieved by the use of systems with coupled thermal and material flows (STMP).
