The thermodynamic quantities for iron monoboride FeB, such as entropy, enthalpy, heat capacity and their temperature dependence, are considered. It is shown, that accounting for contribution to the zeroth-order high-temp...

Abstract Many DNA-based devices need to build stable and controllable DNA films on surfaces. However, the most commonly used method of film characterization, namely, the probe-like microscopes which may destroy the sampl...

Through the laser-wire coaxial additive manufacturing technology, laser melting deposition experiments of GH4169 superalloy under different offsets were carried out, and the effects of different offsets on the microstruc...

Abstract: To investigate the interaction of heterogeneous solutes in the common molten pool flow during laser welding of heat-resistant steel and nickel-based alloy, a multiphase flow coupled welding model was establishe...

In the article, taking into account requirements to the teacher of higher educational establishment, contradictions which must be untied in the process of their professional preparation, the special accent is done on the...

In this work, a series of three and four-color tandem white organic light-emitting diodes (WOLEDs) are developed by using the optimized charge generating unit (CGU) to connect two electroluminescence (EL) units with symm...

The latest developments in the field of materials to improve the physical and chemical properties is the use of physical modification of polymeric materials. The specimens of polyepoxy and composites on the base metal ox...

The current state of development of the Ukrainian state requires further reform of all spheres of life of the Ukrainian community. The democratization of the principles of higher education needs special attention. Since ...

Objective Acinetobacter baumannii, a prevalent multidrug resistant (MDR) pathogen, poses a significant threat to critically ill patients. This work aims to analyze the genomes of eight clinical carbapenem-resistant A. ba...

The article is devoted to the study of the concept of "Slow Food" as one of the effective tools for preserving gastronomic heritage and implementing the principles of sustainable development in the context of globalizati...

Abstract The soil bacterium Pseudomonas putida injects toxic proteins into neighbouring competitors, including resilient phytopathogens, using the Type VI secretion system (T6SS). The secretion of toxins endows P. putida...
