Considering the nonlinear characteristics of dilatancy and strength of coarse-grained materials, an elastoplastic constitutive model based on microstructures is established within the framework of classic elastoplastic t...

Experimental researches on undisturbed soil samples are of great significance for the oil and gas exploitation in South China Sea. The physical and chemical properties of seabed soil in the slope area of South China Sea ...

This study reports the changes in fatty acids, taste, and microstructure of cooked southern king crab meat (Lithodes santolla) during storage at 0°C for 10 days and at −20°C for 90 days. At the end of both storage ti...

An all-solid waveguide array fiber (WAF) is one kind of special microstructured optical fiber in which the higher-index rods are periodically distributed in a low-index silica host to form the transverse two-dimensional ...

Many studies have shown how pigments and internal nanostructures generate color in nature. External surface structures can also influence appearance, such as by causing multiple scattering of light (structural absorption...

Chemical modification of chitosan, specially grafting with different polymers is an important strategy in the production of bio-based materials with enhanced properties. In the present study, chitosan was grafted with n-...

For Fe-В and Fe-В-С system alloys one of the structure constituent is iron boride Fe<sub>2</sub>B but in the literature there is no information on carbon solubility limit in iron boride Fe2В. The object ...

In this work using sol-gel auto-combustion synthesis was synthesised single-phase magnesium-substituted lithium ferrite at different pH reaction medium. The synthesized materials were investigated by X-ray and Mossbauer ...

The effect of the support shape on the deposition of ZrO2 by the vacuum-assisted dip-coating method was studied. Disc-shaped and tubular porous stainless steel substrates were used to obtain ZrO2 coated supports for the ...

El léxico del transporte aéreo se ha nutrido con el trasvase de términos de otras modalidades de locomoción, de ciencias como la meteorología o la ornitología y ha incorporado préstamos de distintas lenguas. Si bi...

Based on the actual state of the soil along rail transit in hot and rainy area, the resonant column tests on the soil under wetting and drying circles are conducted to study the stiffness characteristics of residual soil...

To illustrate the variation laws of strength characteristics and micromechanism of rubber-sand mixtures, a series of laboratory tests including direct shear tests, unconfined compressive strength tests and scanning elect...

Quasicrystalline aluminium alloys and aluminium based nanocomposites with the advantage of high strength over commercial aluminium alloys have been studied for many years. In this work a nanoquasicrystalline Al-Fe-Cr-Ti ...

The colour of birds' plumage is due to the presence of pigments as well as to frequency selective structural effects produced by the interaction of light with the photonic microstructure that constitutes the feather barb...

Ultracompact chip-integrated all-optical half- and full-adders are realized based on signal-light induced plasmonic-nanocavity-modes shift in a planar plasmonic microstructure covered with a nonlinear nanocomposite layer...

Lightweight and low-cost organic photovoltaics (OPVs) hold great promise as renewable energy sources. The most critical challenge in developing high-performance OPVs is the incomplete photon absorption due to the low dif...

Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregula...
