Synergic nature of dielectric relaxation process in the layered perovskite halide salts: The case of 1,3- diammoniumpropylenetetrabromocadmate compound

Abstract: The negative thermal expansion (NTE) property was a prototype to discuss the origin of difference between classical Debye relaxation process and the non-Debye behavior in the layered perovskite halide salt of chemical formula NH3(CH2)3NH3CdBr4. The analysis has been taken by dielectric relaxation spectroscopy measurements in almost six decades in frequency 5 × 102 ≤ f ( ω ) ≤ 1.2 × 108 and in the temperature range 315 ≤ T(K) ≤ 390. It was shown that the investigated sample exhibit an antiferrodistortive nature of phase transition between two orthorhombic structural modifications i.e. Pnma (phase I) and Ima2 (phase II) at T c 1 ( I → I I ) = 326 K, leading from an antiferroelectric to a paraelectric phase. The involvement of an odd number of carbon atoms in the alkylammonium chains in dielectric properties of examined sample is proved. Higher structural modifications, i.e. Ima2 (phase II) and P21/m (phase III), have shown significant deviations from a regular circle on the Cole-Cole diagram. Presented experimental observations are essentially important for the theoretical explanation of relaxation processes in analyzed organic – inorganic compound crystallizing in a perovskite-like topology and may provide new perspective on the fundamental aspect of relaxation response in “diammonium” series.

Autohesion of Inorganic Compound Powders

Abstract: Abstract The article begins with analytical review of the works performed from 1940 up to nowadays, concerning the phenomenon of autohesion in the powders of inorganic compounds. The issues of terminology are concerned, the difference is discussed between the phenomena of autohesion, adhesion, and cohesion. Three groups of the components of autohesion forces are considered: van der Waals and electrical forces, cohesion and capillary forces and mechanical cohesion, as well as internal and external factors affecting these forces. The second part of the article is devoted to the results of experiments performed to study the influence of the autohesion forces on the properties of friable inorganic powder materials. In particular, the rheological properties of powders were studied by static and dynamic methods on four kinds of electrocorundum powder with similar particle size and particle size distribution corresponding to the class of grinding powders F1200 according to FEPA standard. Special attention is paid to assessing the effect of humidity on technological properties of the powder, obtained by spray drying of ceramic slurry. This powder is widely used as a component of building mixes. The authors came to conclusion that detailed study is necessary of the autohesion effect on the parameters of friable systems for the rational choice of technological modes. The work can be useful for researchers and practitioners associated with the problems of processing, storage and transportation of powder materials.

Where and How Does an Organic Molecule Having a C-X Bond Release X- Anion Like an Inorganic Compound? A Theoretical Study.

Abstract: In this research, at first, a comparative DFT study on hydride or fluoride release from a number of known orthoamides, their fluorine derivative having a central C–F bond and some simple organic compounds, is reported. The obtained data show that orthoamides release hydride or fluoride anions much easier than do other known organic compounds studied here. Interestingly, three simulated orthoamides having a central C–F bond, spontaneously and like an inorganic compound, release fluoride anion upon dissolving in polar solvents. The calculations confirmed that hyperconjugation interactions in the initial orthoamides facilitate the anion release from these compounds. However, the data clearly show that the proper overlap of an empty p orbital of the central carbon atom with adjacent lone-pair orbitals of nitrogen atoms (lpN → lp*C or, in other words, the pπ–pπ interaction) in the resulting carbocations is a more important factor that must be taken into consideration when designing the hydride, fluoride, or ot...
