This work describes the synthesis and quadratic nonlinear optical properties of hybrid nanoparticles. These nanoparticles are based on the insertion of the push−pull 4-[2-(4-dimethylaminophenyl)azo]-1-methylpyridinium chromophore in the manganese hexathiohypodiphosphate MnPS 3 inorganic matrix. The included chromophor…

Some films obtained from poly(ε-caprolactam) (polyamide 6) and its copolymers with laurolactam (copolyamides 6/12) were submitted to thermal treatment. The most versatile method for characterization of polyamide and its copolymers, i.e., FT-IR spectroscopy, was chosen as a tool in order to determine the possible chang…

In order to provide the uniformity of measurements at the nanoscale, seven national standards have been developed in the Russian Federation. Of these seven standards, three standards specify the procedures of fabrication and certification of linear measures with the linewidth lying in the nanometer range. The other fo…

Ozone emission in hydro generators is a sign of surface partial discharge (PD) in the stator windings. Surface PD activity can take different forms: slot PD, corona at the junction of the slot semiconductive coating with the voltage grading coating outside the slot, PD between adjacent coils in the end-winding, PD bet…

Vascular diseases are a major threat to human health nowadays. While current treatments can cure some vascular diseases, their beneficial effects are only temporary; vascular regeneration holds the promise of permanent, effective treatments for many vascular diseases. Stem cells and endothelial progenitor cells can di…

Using a transmission electron microscope and a nanomanipulator, we explored the early head-to-head coalescence of two capped carbon nanotubes (CNTs) under induction of electric current. We measured detaching forces for coalesced CNTs, showing discrete identifiable values attributable to van der Waals interaction, sing…

Mesoscopic-particle–based fluid models, such as dissipative particle dynamics, are usually assumed to be coarse-grained representations of an underlying microscopic fluid. A fundamental question is whether there exists a map from microscopic particles in these systems to the corresponding coarse-grained particles, suc…

A tomographic study of electrochemical cells to observe scales formed on inert anodes has been conducted using energy-dispersive synchrotron X-ray diffraction. This study is preparatory to an investigation that will observe this formation in situ during the cells' operation. The purpose of the current work was to dete…

The present paper concerns with the concept of the strain rate intensity factor in rigid plastic solids. The strain rate intensity factor is the coefficient of the principal singular term in the expansion of the equivalent strain rate in a series in the vicinity of maximum friction surfaces. Such singular velocity fie…

We consider the spectrum of the Fibonacci Hamiltonian for smallvalues of the coupling constant. It is known that this set is aCantor set of zero Lebesgue measure. Here we study the limit, as thevalue of the coupling constant approaches zero, of its thickness andits Hausdorff dimension. We announce the following result…

Abstract A microbial cellulose film (pellicle), prepared by Acetorbactor xylinum , is a supramolecule system, absorbing a huge amount of water (99% by weight). To elucidate the affinity to water, we investigated the hierarchical structure in a pellicle by using ultra‐small‐angle and small‐angle neutron scattering, obs…
