Currently, lithium-ion batteries are the most commonly used chemical sources of current. When considering the evolution of modern electronic devices, there is a clear tendency towards their miniaturization and increased functionality. This leads to a significant increase in energy consumption, which, in turn, requires the creation of more efficient and compact sources (accumulators) of...

Nontronite belongs to phyllosilicates group. It is an example of layered clay minerals of prominent sorption properties. Layered minerals form structures consisting of tetragonal and octahedral sheets. Our team focused on the unique properties of aluminosilicates and used them for modification using solvents with a constant dipole moment. The process is called intercalation.

Using the estimate of the characteristic length by the Heisenberg's uncertainty principle and the WKB method, the relationship between the London penetration length and the coherence length for HTSC is obtained. The relationship between the London penetration length and the wavelength of plasma oscillations is considered, on the basis of which an expression is obtained for the velocity of a...

Nuclear cross sections strongly depend on neutron energy (e.g. their behaviors in resonance regions). To represent some reactions of resonant nuclides accurately, more than 100,000 energy points are required. Most nuclear codes cannot handle this vast amount of data. That is why, the pointwise cross sections are averaged over energy groups to form multi-group cross sections. These group...

Recently studies of complex cobalt oxides have attracted wide scientific interest, due to the large variety of physical properties found in these materials. In contrast to manganites or cuprates, cobaltites have a unique feature - the ability to change the spin state of Co3+ ions with variations in thermodynamic parameters (temperature or pressure). So, depending on the balance of comparable...

One of the limiting factors of the charge/discharge rate of lithium-ion batteries and related systems is the low mobility of alkali metal atoms in the anode material. Graphene-based anode materials can improve this and a number of other characteristics. The mobility of atoms in graphene or other intercalates is determined by a number of characteristics associated with lattice vibrations. In...

Noble metal nanoparticles are of great interest for a wide range of disciplines due to their unique optical properties. In particular, silver nanoparticles exhibit strong light absorption in the UV range. This phenomenon arises due to the plasmon resonance effect, which can be configured by changing the synthesis technology.
