Supercritical CO2 (scCO2 ) is an environmentally friendly solvent, but its low polarity limits the solubility of polar compounds. Cosolvents are commonly used to enhance solvation capability, yet comprehensive datadriven studies are scarce. We compiled the largest dataset to date — 4401 experimental solubility records with 22 cosolvents for 93 nonionic solutes, plus 4855 records ...

The first-principle modeling of two different quasi-two-dimensional phases based on the volume phases Cr2Te3 and CrTe3 is carried out. Structural relaxation of the obtained 2D compounds and their volumetric prototypes was performed within the framework of the density functional method and the projection plane wave method. Magnetic anisotropy in various crystallographic planes of quasi-two-dimensional structures and corresponding ...

Activation pruning reduces neural network complexity by eliminating low-importance neuron activations, yet identifying the critical pruning threshold—beyond which accuracy rapidly deteriorates—remains computationally expensive and typically requires exhaustive search. We introduce a thermodynamics-inspired framework that treats activation distributions as energy-filtered physical systems and employs the free energy of activations as a principled evaluation metric. Phase-transition–like phenomena ...

Room temperature ionic liquids show great promise as electrolytes in various technological applications, such as energy storage or electrotunable lubrication. These applications are particularly intriguing due to the specific behavior of ionic liquids in nanoconfinement. While previous research has been focused on optimizing the required characteristics through the selection of electrolyte properties, the contribution of ...

In this work, a new method of searching a most energetically favorable free energy calculated along different thermal expansion paths of a compound is proposed. This makes it possible to reduce the problem to a one-dimensional case and to consider free energy as having one variable - volume. The method was applied to study the ...

Although many models explain the spontaneous alternation between two distinct sleep states, Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM), new empirical evidence has accumulated regarding consistent temperature changes during sleep stage transitions in small animals. The temperature dependence of neuro-excitability and low-frequency (≤4 Hz) neuronal activity has also been investigated theoretically and experimentally. ...

Рассмотрены гониометрические методы измерений показателя преломления оптически прозрачных материалов. Предложен модифицированные метод, основанный на методе наименьшего отклонения, позволяющий определять показатель преломления трехгранных призм с неизвестными преломляющими углами. В предложенном методе производят измерения углов отклонения света на трех гранях призмы, а показатель преломления материала и преломляющие углы определяют из решения системы уравнений. Приведена оценка влияния погрешности ...

The march of events which have been unfolding in the last three decades in Northern Eurasia requires clarification and extension of the terminology used in the empire studies, and first of all, the supplement of the wide-spread “center-periphery” model with a third, intermediate element – the notion of “core”. The “core”, in contrast to the ...

A detailed investigation of a superconducting spin-triplet valve is presented. This spin valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic order, which could result from competing isotropic exchanges or, if the crystal lattice breaks central symmetry, from asymmetric Dzyaloshinskii-Moriya exchange. Depending on the anisotropy, such a metal may change ...

Molecular magnetism and specifically magnetic molecules have recently gained plenty of attention as key elements for quantum technologies, information processing, and spintronics. Transition to the nanoscale and implementation of ordered structures with defined parameters is crucial for advanced applications. Single-walled carbon nanotubes (SWCNTs) provide natural one-dimensional confinement that can be implemented for encapsulation, nanosynthesis, and ...
