“…All this will complement the existing developments in the field of hydrogen energy [67][68][69][70][71][72][73]. Of course, the main role in the properties of a nanomaterial is played by the type of system, which can be single-component [74][75] or multicomponent [76][77][78][79]. No less important is the technology of preparation [80][81][82][83][84][85] and processing of the material before its use, which confirms the theoretical [90][91][92] and experimental [93][94][95][96][97][98][99][100] data.…”

The article discusses the use of KDP ferroelectric crystals (phosphates and arsenates of potassium, rubidium, cesium) and their deuterated analogues in various industries, including the creation of electro-optical devices and as hydrogen sorbents. The paper describes the physical properties of KDP crystals, changes in their properties near the phase transition temperature, as well as methods for obtaining KDP nanocrystals and their application in biomedicine. The paper also states that the phase transition in KDP crystals occurs near room temperature and manifests itself in a change in their physical properties, such as dielectric constant, optical properties, and heat capacity. In addition, approaching the phase transition temperature causes a change in the crystal lattice parameters, which can lead to the appearance of anomalous effects. The structure of the unit cell of potassium dihydrogen phosphate (KH2PO4) is considered. The plots of the temperature dependence of the order parameter of spontaneous polarization and the plots of the temperature dependence of the configurational heat capacity of the crystal in the phase transition region are calculated, and the plots of the temperature of the inverse and direct dielectric susceptibility are calculated. Graphs of the order parameter, which characterizes the degree of spontaneous polarization for different temperatures, depending on the strength of the external electric field, are also calculated.

“…A caracterização do pó e a sinterização dos aços rápidos M3:2 com e sem a adição de carbono (grafite) foi objeto de trabalhos anteriores e de outros autores. (9)(10)(11)(12) As amostras dos aços rápidos M3:2 sinterizados a vácuo foram fabricadas sob condições de produção a uma temperatura de sinterização de 1263 C para o aço rápido sem a adição de carbono (grafite) e 1240 C para o aço rápido com a adição de carbono (grafite) durante 1 hora, submetidas a subsequente tratamentos térmicos de recozimento e endurecimento. As sinterizações produziram microestruturas aceitáveis e densidades em torno de 98% da densidade do material (8,16 g/cm 3 ).…”

ResumoO endurecimento secundário de aços rápidos AISI M3:2 produzidos por metalurgia convencional e por diferentes técnicas de metalurgia do pó é objeto desse trabalho de pesquisa. O aço rápido Sinter 23, obtido por sinterização com compactação isostática a quente e o aço rápido M3:2 obtido por compactação uniaxial a frio e sinterização com fase líquida com e sem a adição de 0,3%C (na forma de grafite) e o aço rápido convencional VWM3C foram submetidos ao tratamento térmico de endurecimento e tiveram suas propriedades de dureza Rockwell C e Vickers avaliadas no sentido de estabelecer comparações entre os mesmos levando-se em conta as suas respostas ao tratamento térmico utilizado e a dterminação dos seus picos de endurecimento secundário. Os aços rápidos em questão foram austenitizados a 1140, 1160, 1180 e 1200 C e revenimento a 540, 560 e 580 C. Amostras dos aços rápidos foram fabricadas e submetidas ao tratamento térmico acima descrito e submetidas a ensaios de dureza Vickers e Rockwell C para a determinação das suas respostas ao tratamento térmico de endurecimento e avaliação do pico de endurecimento secundário.

The article discusses methods for obtaining carbon nanostructures (CNS), as well as their use to create three-dimensional (3D) products using FDM, CJP, SLA, SLS technologies. The process of manufacturing consumables for 3D printing technologies (FDM, CJP, SLA, SLS) for creating new composite 3D products based on carbon nanostructures is described. The paper contains a detailed description of which methods of CNS synthesis are more productive and how they allow you to guarantee the production of one or another type of CNS. The paper analyzes the existing 3D printing technologies using CNS, developed a scheme for the full cycle of creating a 3D product containing CNS, taking into account various methods for the synthesis of CNS with the transformation of graphite or other carbon-containing material. It also describes the process of creating composite coils for FDM 3D printing from nanocomposite filaments (rigid polymer-CNS) based on a rigid polymer, which have undergone the process of preparation in a special mixer. The process of preparing consumables and printing a 3D volumetric product using FDM, CJP, SLA, SLS technologies using CNS is described. An overview of consumables for 3D products of FDM technology is presented. The analysis of composite 3D products (ceramic-CNS, rigid polymer-CNS) obtained by FDM and CJP technology was carried out. The paper also describes the three most productive methods for the synthesis of CNS: plasma-chemical synthesis in gas or liquid and pyrolytic method. These synthesis methods make it possible to guarantee the production of a certain type of CNS and have a high quality of the obtained nanoproducts. Various types of CNS are described, including soluble (fullerenes and fullerene-like structures) and insoluble nanostructures (graphenes, carbon nanotubes, carbon nanofibers, nanocomposites, etc.).
