National and patriotic traditions of upbringing in Russia: history and modernity

The paper discusses survey results of a complex and multifaceted phenomenon – the fundamentals of national education and upbringing of younger generations. It is known that the idea of multiculturalism in upbringing is currently recognized as untenable. That is why Europe and other countries of the world, again, turned to the basics of traditional upbringing, where religions continue to hold their place like a moral tuning fork

Cytochrome P450scc spin state transitions in the thin solid films

Langmuir-Blodgett films of cytochrome P450scc were prepared on the solid supports and their spectral properties were investigated. Being immobilized, hemoprotein changes its spin state from initially high to low spin. This transition is reversible since after the solubilization of hemoprotein, the spin state equilibrium is shifted towards high-spin state. Anaerobic reduction of film incorporated cytochrome P450scc by electron transfer chain (NADPH-->adrenodoxin reductase-->adrenodoxin) revealed the low rate of the reaction that coincides well with the content of the hemoprotein low-spin form. We suggest that particularly regular orientation of solid cytochrome P450scc are of crucial importance for this phenomenon

Langmuir-Schaefer films of a polyaniline-gold nanoparticle composite material for applications in organic memristive devices

Langmuir-Shaefer films of a polyaniline-gold nanoparticle composite were fabricated and characterized. The thickness of each deposited monolayer, determined with AFM, was found to be about 0.8 nm. The film morphology was studied by SEM, revealing the presence of embedded spherical-shaped gold nanoparticles of about 5-10 nm in diameter. The fabricated films were used as the active channel of the organic memristor. Its electric characterisation has revealed new phenomena, such as an increased working voltage range and sigmoidal voltage current characteristics that were connected to the charge trappin

The Role of the Internal Capacitance in Organic Memristive Device for Neuromorphic and Sensing Applications

Organic electronics has recently emerged as a promising candidate for the emulation of brain-like functionalities, especially at the device level. Among the proposed technologies, memristive devices have gained an increasing attention due to their non-volatile behavior which makes them suitable for the implementation of artificial neuronal networks. However, most of them have an energy-costly switching mechanism which limits the approach of brain like energy efficiency. Different from them, organic memristive devices (OMDs) have a narrow switching window and implement neuromorphic characteristics at voltages <= 1 V. Despite OMDs potentialities in bioinspired electronics, guidelines for the design of devices and materials are still missing. Here it is shown that the device capacitance represents a significant degree of freedom for targeting devices applications. It is also shown that a single OMD emulates activity dependent synaptic functions and neuronal temporal and spatial summation, taking advantage of its three-terminals configuration. Interestingly, despite the neuromorphic applications, OMDs can also sense and amplify incoming signals on the basis of their capacitive and/or resistive values. This spectrum of applications, ranging from volatile to non-volatile characteristics and from neuromorphic computing to bio signals sensing, sets the stage for the realization of integrated circuits for adaptive sensing

On the Interpretation of Hysteresis Loop for Electronic and Ionic Currents in Organic Memristive Devices

Being promising elements for neuromorphic computation, memristive devices have been often described as crucial elements for mimicking important synapse properties, such as memory and learning. Among them, organic memristive devices (OMDs) can claim low-cost fabrication processes and the easy tunability of their electrical properties. Up to now, the major bottleneck for their larger uses in neuromorphic computation is low rate of the resistance switching and stability. Herein, a new approach is reported, based on the use of a liquid electrolyte, leading to the manufacturing of OMD with higher stability and faster resistive switching

Effect of catalytic aquathermolysis on high-molecular-weight components of heavy oil in the ashal'cha field

© 2015 Springer Science+Business Media New York. We have studied the effect of catalytic aquathermolysis on the high-molecular-weight components of crude oil in the Ashal'cha field (Republic of Tatarstan). We used an iron(III) tris(acetylacetonate) complex as the catalyst. The change in the structure and composition of the resins and asphaltenes in aquathermolysis was studied by PMR and IR spectroscopy
