- ПубликацияТолько метаданныеTechnology of SMD MOX gas sensors rapid prototyping(2020) Samotaev, N.; Oblov, K.; Veselov, D.; Podlepetsky, B.; Etrekova, M.; Volkov, N.; Zibilyuk, N.; Самотаев, Николай Николаевич; Облов, Константин Юрьевич; Веселов, Денис Сергеевич; Подлепецкий, Борис Иванович; Этрекова, Майя Оразгельдыевна© 2020 Trans Tech Publications Ltd, Switzerland.This work discusses the design of flexible laser micromilling technology for fast prototyping of metal oxide based (MOX) gas sensors in SMD packages as an alternative to traditional silicon clean room technologies. By laser micromilling technology it is possible to fabricate custom Micro Electro Mechanical System (MEMS) microhotplate platform and also packages for MOX sensor, that gives complete solution for its integration in devices using IoT conception. The tests described in the work show the attainability of the stated results for the fabrication of microhotplates.

Innovative claims include: demonstration of flexible opportunities for new fabrication process flows based on laser micromilling tech; modeling of power consumption MEMS microhotplate depending on the thickness and topology; demonstration of necessity changing thick film technology of metallization to vacuum sputtering by reducing of power consumption. The results show possibility to fast fabrication of different topologies for ceramic MEMS microhotplate in form-factor of SOT-23 type SMD package.
- ПубликацияТолько метаданныеThin platinum films topology formation on ceramic membranes(2020) Samotaev, N.; Oblov, K.; Etrekova, M.; Ivanova, A.; Veselov, D.; Gorshkova, A.; Самотаев, Николай Николаевич; Облов, Константин Юрьевич; Этрекова, Майя Оразгельдыевна; Иванова, Анастасия Владимировна; Веселов, Денис Сергеевич© 2020 Trans Tech Publications Ltd, Switzerland.This article presents the technological aspects of experiments on the stable topological patterns formation from thin films of platinum on ceramic membranes. Platinum thin films were deposited by magnetron sputtering on a clean or pre-activated laser ceramics surface. After the deposition of platinum films, the method of various short-term laser irradiation was attempted to form a topological pattern. The results are discussed.
- ПубликацияТолько метаданныеIron collector recycling by electrochlorination method(2020) Tietz, A.; Antonov, A.; Samotaev, N.; Veselov, D.; Kirichenko, A.; Самотаев, Николай Николаевич; Веселов, Денис Сергеевич© 2020 Trans Tech Publications Ltd, Switzerland.Modern methods of recycling spent automotive catalysts and their main disadvantages in industrial practice are considered. The electrochlorination method is proposed as the basis of the platinum-group metals extraction technology after electric arc melting of ceramic catalysts carrier material. The results of the experimental work on the extraction of platinum, palladium, rhodium are analyzed.
- ПубликацияТолько метаданныеEffective method for the platinum group metals extracting from spent diesel autocatalysts(2020) Tietz, A.; Antonov, A.; Samotaev, N.; Tsarev, G.; Veselov, D.; Kirichenko, A.; Самотаев, Николай Николаевич; Веселов, Денис Сергеевич© 2020 Trans Tech Publications Ltd, Switzerland.The team of authors described a solution to the problem of developing a fundamentally new technology for the industrial processing of spent diesel automotive catalysts containing platinum group metals (PGM) and SiC carrier, which has such advantages as carrying out a full processing cycle in one hardware module. The processing of SiC catalyst is extremely difficult by pyrometallurgical methods, but proposed technology is based on the electrochlorination method. The scientific novelty of the proposed method lies in the superposition of two independent electrolysis processes in direct and alternating, with varying frequency, currents under conditions of forced, continuous and complete recondensation of the electrolyte. The study of the diesel catalysts processing by the electrochlorination method have carried out.
