Аннотация: Polymer-based dielectric capacitors play a notable part in the practical application of energy storage devices. Graphene oxide (GO) nanosheets can improve the dielectric properties of polymer-based composites. However, the breakdown strength will greatly reduce with the increase of GO content. Hence, the construction of sandwich structure can enhance the breakdown strength without reducing the dielectric constant. Herein, single-layered and sandwich-structured poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-CTFE)) nanocomposites with low content of GO nanosheets (<1.0 wt%) are prepared via employing a straightforward casting method. Compared with the single-layered composites and pure P(VDF-CTFE), the sandwich-structured composites exhibit comprehensively better performance compared. The sandwich-structured composite with 0.4 wt% GO nanosheets show an excellent dielectric constant of 13.6 (at 1 kHz) and an outstanding discharged energy density of 8.25 J cm−3 at 3400 kV cm−1. These results demonstrate that the growth of the dielectric properties is owing to 2D GO nanosheets and the enhancement of breakdown strength due to the sandwich structure. The results from finite element simulation provide theoretical support for the design of high energy density composites.

    High-strength building material based on a glass concrete binder obtained by mechanical activation / S. S. Dobrosmyslov, V. E. Zadov, R. A. Nazirov [et al.] // Buildings. - 2023. - Vol. 13, Is. 8. - Ст. 1992, DOI 10.3390/buildings13081992. - Cited References: 26 . - ISSN 2075-5309

Кл.слова (ненормированные):
glass -- building materials -- mechanical activation -- waste processing
Аннотация: As part of the work, the chemical interaction of finely ground glass (~1 μm), calcium oxide, and water was studied. It is shown that an increase in the fineness of grinding makes it possible to abandon autoclave hardening in the production of products on a hydrosilicate binder. The study of chemical interaction was carried out by calculating the thermodynamic equilibrium and was also confirmed by XRD analysis. DTA analysis showed that an increase in the treatment temperature leads to an increase in the proportion of the reacted phase at the first stage. Subsequently, phase formation is associated with the presence of CaO. The carrier of strength characteristics is the CaO×2SiO2×2H2O phase. The selection and optimization of the composition make it possible to obtain a high-strength glass concrete material with a strength of about 110 MPa. The micrographs of the obtained samples correspond to classical hydrosilicate systems.

Кл.слова (ненормированные):
copper electrodeposited composite coatings -- aluminum-oxide nanopowder -- alumina -- microstructure -- microhardness -- ultimate tensile strength
Аннотация: Copper electrodeposited composite coatings containing two types of aluminum-oxide powders with different dispersities (alumina Al2O3-1 and electroexplosive aluminum-oxide nanopowder Al2O3-2) are obtained during the work. The studies show that introducing the powders leads to a change in the microstructure of the composites and a change in the grain growth principles during the formation of the coatings. Refinement and ordering of the grain structure of the coatings occurs and twinning defects and texture are formed. The change in the formation of the microstructure of the composites leads to a change in some operational characteristics: an increase in the microhardness (by 10% in the composites with the addition of alumina and by more than 30% in the coatings with electroexplosive aluminum oxide) and ultimate tensile strength (by 20% in the composites with Al2O3-1 and almost 1.5-fold in the samples with Al2O3-2).

Кл.слова (ненормированные):
high-nitrogen steel -- austenite -- ultrasonic forging -- electron beam treatment -- aging -- CrN -- strength -- plasticity
Аннотация: The structure and mechanical properties of austenitic high-nitrogen steel (16.5 Cr, 18.8 Mn, 0.07 C, 0.53 N, 0.52 wt % Si, Fe for balance) have been investigated after severe deformation–heat treatment, which has involved shock surface forging at the ultrasonic frequency (USF) and electron-beam heat treatment (EBT). A subgrain structure hardened by CrN nanoparticles has been shown to form in the surface layer as a result of deformation–heat treatment. No discontinuous decomposition of austenite with the formation of Cr2N nitrides takes place. This structure modification in the surface layer enhances the strength properties of the steel, namely, σ0.2 increases to 712 MPa and σu to 923 MPa at a plasticity of 25%. The yield strength increases by 50% compared to the state after quenching.

borates -- "Lu-Ban stool"-like structure -- ultraviolet transparency -- zero -- linear compressibility
Аннотация: Discovering materials that exhibit zero linear compressibility (ZLC) behavior under hydrostatic pressure is extremely difficult. To date, only a handful of ZLC materials have been found, and almost all of them are ultrahard materials with densified structures. Here, to explore ZLC in nondense materials, a structural model analogous to the structure of the “Lu‐Ban stool,” a product of traditional Chinese woodworking invented 2500 years ago, is proposed. The application of this model to borates leads to the discovery of ZLC in AEB2O4 (AE = Ca and Sr) with the unique “Lu‐Ban stool”‐like structure, which can obtain a subtle mechanical balance between pressure‐induced expansion and contraction effects. Coupled with the very wide ultraviolet transparent windows, the ZLC behavior of AEB2O4 may result in some unique but important applications. The applications of the “Lu‐Ban stool” model open a new route for pursuing ZLC materials in nondense structural systems.

Аннотация: Recently, a borate crystal Zn4B6O13 (ZBO) has been focused on since it exhibits novel isotropic near-zero thermal expansion behavior in a wide temperature range. In this work, the mechanical properties in ZBO are studied by high-pressure X-ray diffraction and first-principles calculations. It is found that ZBO possesses the highest mechanical hardness in all known borates whose mechanical properties have been measured. The very high mechanical strength in ZBO mainly originates from the resistance of strong Zn-O bonds to the rotation among BO4 tetrahedra in the unique sodalite-cage structure. Moreover, ZBO shows relatively high mechanical resistance to the axial and shear stress and exhibits high optical transparence in the ultraviolet spectral region under high pressure. Benefitting from these good properties, ZBO may find potential applications in high-precision optical facilities used at extreme conditions under complex environments. © The Royal Society of Chemistry.

Аннотация: The diagram series structure for Matsubara Green's functions in the Hubbard operators representation have been analyzed for the superconducting (SC) phase in the t-J-model. It has been found that the Hubbard operator diagram technique besides anomalous self-energy operator includes also anomalous strength operator (ASO). With account for ASO Gor'kov equations have been written. ASO are shown to be very essential when anomalous averages are calculated. The anomalous self-energy operator and ASO were derived in one-loop approximation. It has turned out that strength operator components depend oil Matsubara frequency. As a result the SC phase is described by infinite set of integral equations. When deriving the equation for transition temperature in SC phase with s- and d-order parameter symmetry this system has been solved exactly. On the basis of numerical calculations it has been found that the account for strength operator components has fully suppressed SC phase with s-order parameter symmetry in the t-J-model.

Аннотация: We consider resonant vortices around nodal points of the wave function describing electron transport through a mesoscopic der-ice. With a suitable choice of the device geometry. the dominating role is played of single vortices with a preferred orientation. To characterize the strength of the resulting magnetic moment, we have introduced a "magnetance," the quantity defined in analogy with the device conductance. Its basic properties and possible experimental detection are discussed. [S0031-9007(97)05255-1].
