The paper presents the results of an experimental study highly efficient technological process manufacture of the round forging on a crank hot-stamping press. The high efficiency of this technological process is achieved by reducing its metal consumption. To this end, at the final stamping transition, the forging forging radii were reduced and, accordingly, the allowances for subsequent machining were minimized.

AbstractDeposition of perovskite films by antisolvent engineering is a highly common method employed in perovskite photovoltaics research. Herein, we report on a general method that allows for the fabrication of highly efficient perovskite solar cells by any antisolvent via manipulation of the antisolvent application rate. Through detailed structural, compositional, and microstructural characterization of perovskite layers fabricated by 14 different antisolvents, we identify two key factors that influence the quality of the perovskite layer: the solubility of the organic precursors in the antisolvent and its miscibility with the host solvent(s) of the perovskite precursor solution, which combine to produce rate-dependent behavior during the antisolvent application step. Leveraging this, we produce devices with power conversion efficiencies (PCEs) that exceed 21% using a wide range of antisolvents. Moreover, we demonstrate that employing the optimal antisolvent application procedure allows for highly efficient solar cells to be fabricated from a broad range of precursor stoichiometries.

The complexity of the technology of machining by cutting complex surfaces of parts heterogeneous in terms of physical and mechanical properties and different machinability, and, in particular, of metals (aluminum) and plastics (polyurethane and polyethylene), which form an assembly component, a section of the container-type countermine system is defined in the paper. The description of technological process operations of machining of a basic detail of an item, the body, is given. Features, the presence of which creates not only difficulties in the implementation of the technological process of manufacturing a base part, but is not permissible in the operation of a defense-purpose item are revealed. The article proposes design and technological solutions for the use of a new cutting tool design, capable to eliminate errors of creep feed drilling, avoid sticking of the material of the protective shell and casing on the active cutting part, exclude damage to the contact body and thereby ensure the specified performance of the item , Field tests of a container-type countermine system with basic parts manufactured using the new tool and technology have shown high efficiency of the decisions taken.

In this study, we have synthesized the molybdenum sulfide quantum dots (MoS2 QDs) and zinc sulfide quantum dots (ZnS QDs) and demonstrated a highly efficient green phosphorescent organic light-emitting diode (OLED) with hybrid poly (3,4-ethylenedioxythiophene)/poly (styrenesulfonate) (PEDOT:PSS)/QDs hole injection layer (HIL). The electroluminescent properties of PEDOT:PSS and hybrid HIL based devices were explored. An optimized OLED based on the PEDOT:PSS/MoS2 QDs HIL exhibited maximum current efficiency (CE) of 72.7 cd A−1, which shows a 28.2% enhancement as compared to counterpart with single PEDOT:PSS HIL. The higher device performance of OLED with hybrid HIL can be attributed to the enhanced hole injection capacity and balanced charge carrier transportation in the OLED devices. The above analysis illustrates an alternative way to fabricate the high efficiency OLEDs with sulfide quantum dots as a HIL.
