   Перевод заглавия: Method of electric energy recuperation in impulse aggregates, and device for method implementation
Аннотация: Изобретение относится к электротехнике и может быть использовано для генерации импульсов в активно-индуктивных нагрузках. Технический результат состоит в снижении тепловых потерь при перезарядке, в получении однополярных импульсов тока, в отсутствии необходимости коммутации полярности тока дозарядки, в упрощении конструкции и схемы управления ключом. Способ рекуперации электрической энергии заключается в преобразовании магнитной энергии электрического тока, полученной в результате преобразования энергии заряженного емкостного накопителя в магнитную энергию электрического тока, в энергию емкостного накопителя. В течение одного цикла работы импульсной установки преобразование энергии емкостного накопителя в магнитную энергию электрического тока и наоборот производится дважды. На первом этапе энергия емкостного накопителя преобразуется в магнитную энергию тока в активно-индуктивной нагрузке с последующей рекуперацией энергии в емкостный накопитель. На втором этапе энергия емкостного накопителя преобразуется в магнитную энергию тока в катушке индуктивности с последующей рекуперацией энергии в емкостный накопитель. Устройство содержит подключаемый к зарядному устройству емкостный накопитель энергии, параллельно которому подключены последовательно соединенные активно-индуктивная нагрузка и первый ключ. В него введена цепь из последовательно соединенных катушки индуктивности и второго ключа, которая подключена параллельно емкостному накопителю энергии. Первый вывод емкостного накопителя, первый вывод активно-индуктивной нагрузки и первый вывод катушки индуктивности соединены между собой и подключаются к положительному выводу зарядного устройства. Второй вывод активно-индуктивной нагрузки подключен к аноду первого ключа, второй вывод катушки индуктивности подключен к катоду второго ключа. Второй вывод емкостного накопителя, катод первого ключа и анод второго ключа соединены между собой и подключаются к отрицательному выводу зарядного устройства. 2 н. и 5 з.п. ф-лы, 3 ил.

Аннотация: We have studied light induced processes in nanocolloids and composite materials containing ordered and disordered aggregates of plasmonic nanoparticles accompanied by their strong heating. A universal comprehensive physical model that combines mechanical, electrodynamical, and thermal interactions at nanoscale has been developed as a tool for investigations. This model was used to gain deep insight on phenomena that take place in nanoparticle aggregates under high-intensity pulsed laser radiation resulting in the suppression of nanoparticle resonant properties. Verification of the model was carried out with single colloidal Au and Ag nanoparticles and their aggregates. © 2017 Optical Society of America.

CRITICAL NANOAGGREGATE CONCENTRATION
ELECTRON-SPIN-RESONANCE
Аннотация: The tendency of asphaltenes for aggregation followed by precipitation and deposition plays a crucial role in the petroleum industry since these processes present severe problems during the production, recovery, and processing of crude oils and fossil hydrocarbon feedstocks. The dynamics of oil asphaltene aggregates dissolved in chloroform at different concentrations varied in a wide range that was investigated at temperatures from 0 to 55 °C using the Pulsed-Field Gradient NMR technique. The components attributed to nanoaggregates and macroaggregates were successfully resolved, which allowed us to measure their diffusion coefficients. The diffusion coefficients for all types of aggregates grow as the asphaltene concentration decreases, whereas the partial weight of the aggregates increases with the increase of asphaltene concentration. The difference in diffusion behavior of the aggregates of different types was registered when passing the critical concentration range 10–20 g/L. The nano- and macroaggregates behave independently when the asphaltene concentration is higher than 20 g/L (concentrated regime), while below 20 g/L (semidiluted regime) the components related to the different types of aggregates cannot be properly resolved. It was found that regardless of the asphaltene concentration, the diffusion coefficients for nano- and macroaggregates demonstrate similar temperature behavior giving the straight lines in the Arrhenius coordinates which change their slopes when passing the temperature range 20–30 °C. The phenomenon evidences the thermally induced cleavage of noncovalent bonds with subsequent rearrangement of asphaltene aggregates that is observed for all concentration regimes covering the existence of asphaltene aggregates of all types. The data obtained are well consistent with the modern concept of asphaltene aggregate structure and fairly agree with the data obtained earlier. We believe these results will contribute essentially to a better understanding of the fundamental behavior of asphaltenes and their aggregates, providing a deep insight into aggregate transformation triggered by the temperature.

Аннотация: We have shown significant suppression of resonant properties of metallic nanoparticles at the surface plasmon frequency during the phase transition “solid–liquid” in the basic materials of nanoplasmonics (Ag, Au). Using experimental values of the optical constants of liquid and solid metals, we have calculated nanoparticle plasmonic absorption spectra. The effect was demonstrated for single particles, dimers and trimers, as well as for the large multiparticle colloidal aggregates. Experimental verification was performed for single Au nanoparticles heated to the melting temperature and above up to full suppression of the surface plasmon resonance. It is emphasized that this effect may underlie the nonlinear optical response of composite materials containing plasmonic nanoparticles and their aggregates. © 2017, Springer-Verlag Berlin Heidelberg.

Аннотация: We present an experimental spectroscopic study of large random colloidal aggregates of silver nanoparticles undergoing local restructuring. We argue that such well-known phenomena as strong fluctuation of local electromagnetic fields, appearance of "hot spots" and enhancement of nonlinear optical responses depend on the local structure on the scales of several nanosphere diameters, rather than the large-scale fractal geometry of the sample.

Аннотация: Aggregation of asphaltenes followed by precipitation presents severe problems for existing technologies in the production, recovery, and processing of heavy oils. Better understanding of asphaltene behavior behind the processes of their precipitation and dissolution is vital to address this issue. While investigating the inhomogeneity of different oil systems, the reversibility of the asphaltene aggregation process initiated by flocculant in either asphaltene solution in toluene or crude heavy oil was revealed and investigated using magnetic resonance imaging methods. It was found that the inhomogeneous distribution of the flocculant initiates local spatial-selective asphaltene aggregation registered in a thin layer around the flocculant/oil sample interface. The local excess of flocculant concentration over the threshold of asphaltene precipitation onset is a driving force of this process. As the flocculant diffuses into the volume of the sample, a decrease of the asphaltene flocculated area is observed until it disappears when the equilibrium composition throughout the whole volume of the system is achieved. Depending on the overall flocculant concentration, the asphaltene aggregation may not be reversible and could be followed by subsequent precipitation of the asphaltene aggregates. The similarity of the phenomena observed for the model asphaltene solutions and crude heavy oil samples was established. Partial mechanical stirring of the multicomponent system comprising flocculant and oil or asphaltene solution does not prevent the formation of the local zones with increased concentration of asphaltene aggregates; those sizes evolve depending on the flocculant concentration. The results obtained in this work are consistent with the generally accepted concept of asphaltene precipitation reversibility depending on the system composition and are compatible with the observations obtained by other methods. The approach presented can provide deeper insight into the asphaltene precipitation reversibility issue and can facilitate the understanding of asphaltene behavior in heavy oils.
