Bamboo composite is an attractive candidate for structural materials in applications such as construction, the automotive industry, and logistics. However, its development has been hindered due to use of harmful petroleum-derived synthetic adhesives or low-bonding biobased adhesives. Herein, we report a novel bioadhesion strategy based on situ lignin bonding that can process natural bamboo into scalable high-performance composite. In this process, bonds cellulose fibrils strong network via...
Leakage is a common defect of embankment dam slopes, and usually accompanied by internal erosion. This study establishes mathematical two-phase seepage coupling model that explicitly considers the effects With help finite element software COMSOL Multiphysics ® , we use this to characteristics fluid seepage, fraction leakage volume made up migrated fine particles (migrated fraction), porosity, permeability, displacement in process three-dimensional slope, as well influence water level outlet...
BaCe1-xYxO3-α (x = 0.1, 0.15) solid electrolytes were prepared via ball milling raw powders of BaCO3, CeO2 and Y2O3, pressing the powder mixtures into tablets followed by calcining in air. X-ray diffraction analysis indicated that BaCe0.9Y0.1O3-α BaCe0.85Y0.15O3-α solutions synthesized at 1250°C 1400°C, respectively. The electrolyte disks made grinding calcined fine powders, cold isostatic shape sintering 1550°C electrochemical impedance spectroscopy measurements revealed they show useful...
The fluid seepage in saturated zone of subgrade promotes the migration fine particles filler, resulting change pore structure and morphology filler deformation solid skeleton, which affects characteristics. Repeatedly, muddy interlayer, mud pumping, other diseases are finally formed. Based on theory two-phase seepage, porous media principle effective stress media, a fluid-solid coupling mathematical model considering effects is established. numerically calculated with software COMSOL...
Yttria doped ceria display higher ionic conductivity and stabilized phase which possess more advantage for solid oxide fuel cells. By using molecular dynamics simulation, the lattice parameter oxygen of Ce 1-x Y x O 2-x/2 (x = 0 - 0.65) at 1273 k have been investigated. Lattice parameters both increase with yttria doping while < 0.15 but over lead to a decreasing trend on them. It is suggested that closing distance cation-anion responsible this decreasing. The coordination numbers cations...
The latest development on preparation of mullite, mullite-corundum and mullite-zirconia materials using fly ash by reaction sintering process was reviewed. future mullite its composites synthesized from prospected.
In this paper, the latest research development on heat treatment processes, microstructure and mechanical properties of low-carbon martensite steel was reviewed. And effects processes were analyzed.
Phase characterization is critical in material properties probing. In this study, Raman scattering was employed to identify the phase of YSZ co-doped with CeO 2 /Gd O 3 . As a comparing, XRD for also measured. The results show that introducing small amount into can lead change on spectroscopy. peaks appear co-doping attributed local structure which caused by re-distribution vacancy. Comparing XRD, spectroscopy shows more sensitive dopant.
CaZr 0.9 In 0.1 O 3-α and BaCe 0.85 Y 0.15 two kinds of solid electrolytes were prepared, the preparation conditions determined. DSC-TG curves used to illustrate synthetic mechanism , XRD analyses indicate these are single phase after calcining at 1400°C for 10h. The isostatic pressing method hot injection moulding prepare tubes. Through comparing apparent density sintered tubes, it is found that shaping good improving compactness
Using the micron alumina powder for study, through analysis of ceramic suspension rheological, generation and evolution its mechanism aggregates in were studied. The results showed that number, size intensity will be effected by gravitational potential or barrier height between particles as varying process conditions. Generally, formation was corresponded to interaction particles, is, second well. Thus, their internal bonding strength is weak. In flowing suspension, meta-stability under...
A mathematical heat transfer model was built to simulate temperature, shell growth and phase transformations in continuous casting based on the technical conditions of bloom caster some steelmaking plant.
