“…In the first case, L1 is a surfactant, and L2 is a low-molecular-weight ligand, such as H2O, 1,10-phenanthroline, 2,2'-bipyridine, etc. [16]. In the second case, L2 is a surfactant that binds the Ln(III) ion due to the formation of a π-complex, and L1 is a low-molecular-weight chelating ligand (for example, βdiketone) [17,18].…”

“…In the second case, L2 is a surfactant that binds the Ln(III) ion due to the formation of a π-complex, and L1 is a low-molecular-weight chelating ligand (for example, βdiketone) [17,18]. A variant of this approach is the use of an anionic CC of the composition [Ln(L1)m] -, where L1 -is a surfactant [16], or [Ln(L1)m] -(L2 + )n, where L2 + is a cationic surfactant and L1 is a low-molecular-weight chelating ligand [19].…”

In this study, we investigated the effect of terbium ions (Tb3+) on the subphases of the limiting area of the molecule for the complex compound (CC) TbL3∙bipy (where HL is 3-methyl-1-phenyl-4-stearoylpyrazol-5-one and bipy is 2,2’-bipyridine). We examined the Langmuir monolayer and the change in the luminescence properties of TbL3∙bipy-based Langmuir-Blodgett films (LBFs). The analysis of the compression isotherms, infrared, and luminescence spectra of TbL3∙bipy LBFs was performed by varying the concentration of Tb3+ in the subphases. Our results demonstrate the partial dissociation of the CC at concentrations of C(Tb3+) < 5 × 10−4 M.

The trigonal lanthanide complexes LnL (H3L = tris(((3-formyl-5-methylsalicylidene)amino)ethyl)amine) contain three pending aldehyde groups and are known to react with primary amines. Reacting YbL and LuL with 1-octadecylamine yields the novel aliphatic lanthanide complexes (Yb, Lu)L18 (H3L18 = tris(((3-(1-octadecylimine)-5-methylsalicylidene)amino)ethyl)amine) where the three aldehyde groups are transformed to 1-octadecylimine groups. Herein the syntheses, structural characterisation and magnetic properties of YbL18 and LuL18 are presented. The crystal structure of YbL18 shows that the reaction of YbL with 1-octadecylamine leads to only very subtle perturbations in the first coordination sphere of Yb(III), with the Yb(III) ion retaining its heptacoordination and similar bond lengths and angles to the ligand. The three long octadecyl chains in each complex were found to direct crystal packing into lipophilic arrays of van-der-Waals interaction-driven hydrocarbon stacking. The static magnetic properties of YbL18 were compared to that of the non-derivatised complex YbL. The energy level splitting of the 2F7/2 ground multiplet was found, by emission spectroscopy, to be very similar between the derivatised and non-derivatised complexes. A.c. magnetic susceptibility measurements on YbL18 and YbL diluted at 5 % into the diamagnetic hosts LuL18 and LuL, respectively, revealed that the spin-lattice relaxation of both complexes is governed by a low temperature direct process and a high temperature Raman process. In the high temperature regime, the derivatised complex was also found to have faster spin-lattice relaxation, which is likely due to the increased number of phonons in the octadecyl chains.

“…During the coextrusion processing there always appear tasks of choosing the most effective solution variant out of the range of technically (technologically) acceptable ones [6][7]. While planning the technological process of manufacturing the product, these tasks acquire particular forms connected with the choosing of process-dependent parameters for a definite machine, materials, and a product being manufactured.…”

The research identifies the optimality criterion of the technological process of the coextrusion molding of polymer-concrete building structures in the form of volumetric capacity as the correlation between forms quantity and technological cycle time. The set of parameters value constraints is made. The set consists of kinematic constraints, extruder’s maximum power constrain, maximum motor torque constraint for the extruder trouble-free operation, constraint on the stress rate of the shift between layers, constraint on product cooling time, and minimum melt viscosity constraint. As a result, the task of coextrusion molding process improvement reduces to the task of linear programming. With the help of mathematical modelling the dynamics of cooling process of the preform in the mould is studied. The paper scrutinizes the influence of bulging pressure on the plybond strength in the multilayer polymer system in the manufacturing process of different capacity items.
