The problem of pulling the reinforcing bar from the concrete block is urgent for the practice, as it represents the most widespread method of experimental evaluation of characteristics of reinforced-concrete bond behavior, which are necessary for an estimation of the strength and durability of reinforced concrete stru…
Diffusion of helium has been characterized in natural monazite and synthetic LREE phosphates. Polished slabs of natural monazite and flat growth faces of synthetic phosphates were implanted with 100 keV 3 He at a dose of 5 × 10 15 3 He/cm 2 and annealed in 1 atm furnaces. 3 He distributions in monazites following expe…
Mankind has been aware of composite materials since several hundred years before Christ and applied innovation to improve the quality of life. Although it is not clear has to how man understood the fact that mud bricks made sturdier houses if lined with straw, he used them to make buildings that lasted. In recent year…
Recently, there has been renews interest in chitosan as materials in producing of biocomposite films. The chitosan (CS)/corn cob (CC) biocomposite films were prepared by solvent casting method. The effect of CC content on tensile properties of CS/CC biocomposite films was studied. The tensile strength and elongation a…
We formulate and apply a non-replica equilibrium theory for the fluid-glass transition, glass thermodynamic properties, and jamming of hard spheres in three and all higher spatial dimensions. Numerical predictions for the zero complexity glass transition and jamming packing fractions, and a "densest" equilibrium glass…

The objective of this study was to prepare and evaluate rate-controlled 17beta-estradiol nanoparticles (E2-NPs), and then optimize them by central composite design (CCD) using a response surface methodology (RSM). The E2-NPs were designed for cerebral ischemia therapy and prepared by oil-in-water (o/w) emulsion by mix…
Abstract An attempt was made to explore the role of nanoclay surface modifier chemical reactivity on the morphology and the rheological properties of a polypropylene/polyamide6 (PP/PA6 75/25) nanocomposite blend. The Na-MMT surface was modified with two types of cations; a) diamine cation (D-Clay), and b) a combinatio…
In this study, the structure and properties of bisphenol A polycarbonate (BPA-PC) after UVB-313 radiation were investigated. When BPA-PC was exposed to ultraviolet (UV), this polymer showed two different degradation mechanisms: photo-Fries rearrangement and photo-oxidation. The interpretation of the observed chemical…

Atomic fault lines stemming from the linear assembly of epoxy groups are recently proposed to be responsible for the decrease of bulk size of graphitic materials. Yet, the formation of such a line by either the hopping of existing epoxides or the binding with environmental atomic oxygens seems to be infeasible. By emp…
The possibilities of computer experiments performed with the MD-SLAG-MELT v. 10.0 information-research system (IRS) with remote access are described. The main classes of mathematical models and methods and the sets of properties obtained in computer experiments are considered. An information model is developed for an…
The dielectric spectra of CaCu 3 Ti 4 O 12 ceramics with giant values of the dielectric constant have been presented. The spectrum exhibits Debye dispersion with an activation energy of 0.075 eV in the high-frequency range of 10 6 –10 7 Hz, and a characteristic plateau has been seen in the frequency dependence of the…
This study evaluates the local damage of a turbine in an auxiliary building of a nuclear power plant due to an external impact by using the LS-DYNA finite element program. The wall of the auxiliary building is SC structure and the material of the SC wall plate is high manganese steel, which has superior ductility and…
This work reports on the synthesis, spectroscopic characterisation and aggregation behaviour of a range of new silicon phthalocyanines with 2-[3-(trifluoromethyl)phenoxy], 2-{2-[3-(trifluoromethyl)phenoxy]ethoxy}, 2-(2,3,5,6-tetrafluorophenoxy) and 2-[2-(2,3,5,6-tetrafluorophenoxy)ethoxy] groups as axial ligands. The…
A theoretical model to describe the nanovoid growth by emission dislocation shear loop in nanocrystalline metal under equal biaxial remote stress was developed. The critical stress for emission of dislocation was derived by considering the effects of surface stress. Within our description, dislocations emitted from su…
The ferromagnetic resonance (FMR) spectra of thin metallic films obtained by magnetron deposition on polymeric and ceramic substrates are investigated in the strip line at frequencies of 0.13–12 GHz via frequency and external magnetic field sweeping. The influence of mechanical stresses on the FMR spectra of films dep…
The fibrous plants can grow from Northern to Southern Arctic Circle. Different parts of these lignocellulosic plants are valuable sources of lignocellulosic fibres used in textiles and eco-friendly composites, sources of human food, nutrients, animal feed, agro-fine-chemicals for cosmetics and other area of applicatio…
