Abstract: A method for obtaining a salt with a general formula: RxNI, wherein: RxN is an organic cation (RxN+), R represents substituents (R?) independently selected from a group consisting of organic substituents: R1?, R2—, R3— and hydrogen (H—), x is a number of the substituents R— directly linked with the nitrogen (N) atom in the organic cation RxN+, wherein x is 3 or 4, I is an iodide anion (I?). The method comprises: preparing a reaction mixture comprising the steps of: synthesizing hydrogen iodide (HI) in situ by mixing molecular iodine (I2) with formic acid (COOH) in a molar ratio of molecular iodine (I2): formic acid (COOH) of no less than 1.01:1, in a solvent medium, introducing into the solvent medium a compound being a donor of organic cation RxN+ in an amount providing the molar ratio of the donor of organic cation RxN+: molecular iodine (I2) of no less than 1.01:1, and maintaining the reaction mixture at a temperature of not less than 20° C.

Abstract: An optoelectronic foil comprising a substrate and a conductive layer comprising at least one oxide layer and at least one metal layer, wherein between the conductive layer and the substrate of the foil there is a barrier layer comprising at least one material selected from the group consisting of silicon oxides (SiOx), aluminium oxides (Al2O3, AlOxNy), titanium oxides (TiOx), silicon oxynitrides SiON, silicon nitrides (Si3N4, SiNx), organic silicon compounds (SiCxHy), zirconium oxide (ZrO2), hafnium oxide (HfO2), chromium oxides (CrO, Cr2O3, CrO2, CrO3, CrO5) and parylene.

Abstract: Rods with the transverse cross-section surface area of at least 150 mm2 and tensile strength UTS above 1200 Mpa is produced using a plastic deformation that consisted of one-pass hydrostatic extrusion of the billet 1 made of austenitic steel, with the initial temperature of the billet being below 100° C. The reduction R of the transverse cross-section surface area of the biller (1), which takes place during the extrusion, is at least 2.

Abstract: The method consists of subjecting a coarse-grained titanium semi-product (1) with the pure titanium content of at least 99 wt % to a plastic deformation. In said plastic deformation the transverse cross-section surface area of the titanium semi-product is reduced by hydrostatic extrusion in which the titanium semi-product is the billet (1) extruded through the die (4). The reduction (R) of the transverse cross-section of the titanium billet (1) is realized in at least three but not more than five consecutive hydrostatic extrusion passes at the initial temperature of the billet (1) not above 50° C. and the extrusion velocity not above 50 cm/s. Prior to each hydrostatic extrusion pass, the titanium billet is covered with a friction-reducing agent. During the first hydrostatic extrusion pass, the reduction of the transverse cross-section surface area of the titanium semi-product is at least four, whereas during the second and third hydrostatic extrusion pass it is at least two and a half.
