“…The DSC curve (Figure 4) also shows only one exothermic peak, which has a maximum of 300.5 • C, starting at 253 • C and ending at 335 • C. It was in this interval that a significant weight loss occurred. Based on the results of the analysis of DSC, TGA, and DTA, it can be assumed that two processes occur almost simultaneously in the analyzed temperature range: decarboxylation and conjugated polymerization [38]. Decarboxylation is an endothermic process, but the exothermic effect is weakly expressed due to rapid heating (10 • /min) followed by polymerization, which has a significant exothermic effect.…”

In recent decades, metal-containing nanocomposites have attracted considerable attention from researchers. In this work, for the first time, a detailed analysis of the preparation of reactive indicator papers (RIPs) based on silver-containing nanocomposites derived from silver fumarate was carried out. Thermolysis products are silver-containing nanocomposites containing silver nanoparticles uniformly distributed in a stabilizing carbon matrix. The study of the optical properties of silver-containing nanocomposites made it possible to outline the prospects for their application in chemical analysis. RIPs were made by impregnating a cellulose carrier with synthesized silver fumarate-derived nanocomposites, which change their color when interacting with chlorine vapor. This made it possible to propose a method for the determination of chloride ions with preliminary oxidation to molecular chlorine, which is then separated from the solution by gas extraction. The subsequent detection of the active zone of RIPs using colorimetry makes it possible to identify mathematical dependences of color coordinates on the concentration of chloride ions. The red (R) color coordinate in the RGB (red-green-blue) system was chosen as the most sensitive and promising analytical signal. Calibration plots of exponential and linear form and their equations are presented. The limit of detection is 0.036 mg/L, the limits of quantification are 0.15–2.4 mg/L, and the time of a single determination is 25 min. The prospects of the developed technique have been successfully shown in the example of the analysis of the natural waters of the Don River, pharmaceuticals, and food products.

“…[19,20] Among a wide variety of methods for producing nanomaterials, one of the simplest and cheapest approaches is thermolysis of metal compounds, which makes it possible to obtain monodisperse NPs with small defects in the crystal structure and controlled forms. [21][22][23][24] In addition, thermolysis is characterized by cost-effectiveness and environmental friendliness, the ability to easily control the synthesis conditions, the absence of the need for special equipment, complex technological processes, and difficult synthesis conditions. [25][26][27] The main requirements for metal-containing precursors include high purity, ease of handling, storage convenience, non-toxicity, decomposition at low temperatures, etc.…”

A simple and accessible method has been developed for the preparation of copper‐containing nanocomposites by thermolysis of a copper(II) complex with a Schiff base based on 3‐formyl‐4‐hydroxycoumarin and octadecylamine at 500 °C. The resulting nanoparticles with a particle size of up to 85 nm were used as additives to lubricants. It has been established that copper oxide nanoparticles with a concentration of 0.5% and 1% increase the anti‐wear and anti‐friction properties of the lubricant.

“…Интерес к таким материалам обусловлен уникальным сочетанием привлекательных физикохимических свойств наночастиц (НЧ) металлов, их оксидов, карбидов или халькогенидов с пленкообразующими, механическими и другими характеристиками полимеров. Перспективным одностадийным методом конструирования функциональных металлополимерных нанокомпозитов является подход, основанный на (со)полимеризации и превращениях металлосодержащих мономеров (МСМ) [2]. МCМ представляют собой комплексы металлов, содержащие кратные связи, способные вступать в реакции (со)полимеризации [3,4].…”

A number of new metal-containing monomers have been obtained by direct interaction of unsaturated mono- and dicarboxylic acids with silver nitrate. The study of their thermal properties showed that thermolysis proceeds in two or three (for crystalline hydrates) stages. The end products of thermolysis are silver nanocomposites containing metallic silver nanoparticles stabilized by a carbon matrix. Silver particles are located relatively evenly in the object, the amplitude during scanning in a given direction allows us to state that the particles have a shape close to spherical, while some of the large particles, about 30 nm, are aggregates of smaller particles formed during thermolysis.
