The peculiarities of electronic and crystal structures of Zr1-xVxNiSn (x = 0-0.10) semiconductive solid solution were investigated. To predict Fermi level εF behavior, band gap εg and electrokinetic characteristics of ...

In a letter published on March 30, 2021, 24 world leaders have called for global solidarity in the fight against the Covid-19 pandemic. This commitment to act in solidarity with low-income countries however was won under...

This article intends to describe a process of transformation recently affecting the whole Europe. It is the progressive overcoming of welfare State traditionally meant as garantuee for all citizens of the essential servi...

The features of electrokinetic, energy state and magnetic characteristics of ZrNi1-xRhxSn semiconductive solid solution were investigated in the ranges: T = 80-400 K, x = 0-0.10. It was shown that substitution of Ni atom...

Over the past few decades, THz technology has made considerable progress, evidenced by the performance of current THz sources and detectors, as well as the emergence of several THz applications. However, in the realm of ...

Zirconia (ZrO2) is of great importance as a support for systems where high ionic conductivity and mechanical stability are required. Doping/defects have a significant effect on the physical properties of this oxide by st...

Abstract A novel biphasic Dy2Hf2O7-HfO2 composite was synthesized via a solid-state reaction route for potential thermal barrier coating (TBC) applications. X-ray diffraction confirmed that the reaction between Dy2O3 and...

Sulfide superionic conductors (e.g., argyrodite Li6PS5Cl, LPSCl) are extremely promising for all solid‐state batteries, but poor atmospheric stability and high interfacial reactivity limit widespread adoption. Coating ...

Quantum photonic integrated circuits, composed of linear-optical elements, offer an efficient way for encoding and processing quantum information on-chip. At their core, these circuits rely on reconfigurable phase shifte...

The main objective of this research work is to develop a new low-cost isolated three-level ac-dc power converter topology with a reduced number of switches. Existing three-level converter topologies change ac power to dc...

We present a new instrument composed of a large number of sub-electron noise SkipperCCDs operated with a two stage analog multiplexed readout scheme suitable for scaling to thousands of channels. New, thick, 1.35 Mpix se...

A reminder, a review and a look toward the future pros‐ pects for quantum dot-sensitized solar cells — a reminder of the highly viable, energy-efficient solar cells achievable; a review of ground-breaking devices and...

The purpose of this article is to analyse the key trends in Ukraine’s foreign trade reorientation and institutional support of competition under the influence of war and European integration processes. The study focuse...

Flat-band systems have attracted considerable interest in different branches of physics in the past decades, providing a flexible platform for studying fundamental phenomena associated with completely dispersionless band...

Copper metal nanoparticles (Nps) have received increasing interest during the last years due to their potential applications in several fields of science and technology. Their optical properties depend on the characteris...

Crisis of the political mass parties does not necessarily mean party crisis. They buy new strength from the always narrowest relationship which entertain with the state institutions. Parties go back to be of the élites ...

In order to study the practicability delimitating the optimal electrical properties have been studied for soft ferrite system Mn|.xZnxFe204, which prepared by solid state method in the temperature range 300 to 550 K by s...

Platinum catalysts supported on zeolite KY (Si/Al = 12.7), modified with magnesium, calcium or barium, were evaluated in n-octane reforming to produce ethylbenzene. The catalysts were characterized by nitrogen adsorption...
