J. Cent. South Univ. (2019) 26: 2464-2481 DOI: https://doi.org/10.1007/s11771-019-4187-3 Multi-objective optimization of multi-cell conical structures under dynamic loads Pirmohammad Sadjad... 2019 Abstract: In this paper, crashworthiness performance of multi-cell conical tubes with new sectional configuration design (i.e. square, hexagonal, octagonal, decagon and circular) has been......
SDAS decreased by the addition of CNTs for samples which cast from the full liquid state (i.e. A-0-0 and A-0-2). Furthermore, the average cell size declined in the present of CNTs for samples cast from......
. ALAVI-NIA et al [11] investigated crashworthiness capacity of simple and multi-cell thin-walled columns made of aluminum with triangular, square, hexagonal and octagonal cross- sections under quasi-static loading. They observed that the octagonal and hexagonal multi-cell structures have the greatest energy absorbing characteristics. PIRMOHAMMAD and ESMAEILI- MARZDASHTI [12] made an investigation......
was observed with an extension of 1.7% in cell volume. This expansion is translated on XRD patterns (Fig. 3) by a shift of the peaks to smaller 2θ angles [33]. However, heat treatment temperature can......
transport of the complexes is essential to obtain a higher CE. Moreover, (NH4)2SO4 is a good conductive agent, thus a low cell voltage can be realized by increasing c((NH4)2SO4) [5]. [Mn(H2O)6-n(NH3)n]2......
步氧化成Fe3+也将消耗更多的氧,这些因素共同导致矿浆中溶解氧含量的降低.在另一方面,阳极氧化产生的Fe3+易与阴极还原产生的OH-生成铁的氢氧化物,使硫化矿表面亲水性增强[8, 13, 38]. 图2 铁介质与硫化矿物自身形成的局部电池[36-37] Fig. 2 Model of local cell of iron media and sulfide......
. The electrolyte was prepared by dissolving reagents in distilled water and the experiments were performed in a 100 mL plating cell. Direct current was supplied by using a digital coulometer (BHP 2056......
alloys in the cultural heritage artefacts. 2 Experimental 2.1 Electrochemical test The experiments were carried out using a conventional three-electrode electrochemical cell with nitrogen bubbling......
in the unit cell. This composition is close to the ideal ilvaite. Only small amount of Al3+, presumably replacing Fe3+ and Si4+, and a little Mn2+ and Mg2+ replacing Ca2+ and Fe2+ occur......
melting (LSM) provides improved wear and corrosion resistances for Ti-6Al-4V alloys. LSM can also improve biocompatibility by creating a surface roughness that favors cell adhesion and is less time..., GUAN D K, KNOWLES A J, MA Le, DYE D, RAINFORTH W M. Deformation mechanisms in a metastable beta titanium twinning induced plasticity alloy with high yield strength and high strain hardening rate [J......
