Safety evaluation of resistance spot welds necessitates the accurate measurement local constitutive properties. This study employed miniature mechanical tests to investigate deformation and failure behaviors nugget, heat affected zone (HAZ), corona bond welded JSC980YL steel. A novel mini-peel test was developed enable fracture in HAZ for numerical inverse calibration parameters. The constants weld zones calibrated using Cockcroft-Latham ductile criterion were incorporated finite element...

The calcium looping (CaL) process usually employs a dual-fluidized bed (DFB) solid circulating unit. In the regenerator (calcinator or calciner), decomposition of CaCO3 proceeds. To supply heat decomposition, oxyfuel combustion coal is conducted. However, since contains nitrogen, NOx formation occurs during combustion. Because fact that and destruction fuels in fluidized complex process, predictive approach emissions has not yet been sufficiently recognized, especially conditions CaL...

In recent years, several researchers have reported the occurrence of reversible resistance switching effects in simple metal nanogap junctions. A large negative is observed I-V characteristics such a junction when high-bias voltages are applied. This phenomenon characteristic behaviour on nanometre scale; it only occurs for gap widths slightly under 13 nm. Furthermore, exhibits non-volatile hysteresis bias voltage reduced very rapidly from high level to around 0 V, and slowly. change as...

The agglomeration of bed material is a serious problem during biomass combustion. In this paper, an alternative (porous alumina) was used to prevent defluidization and improve efficiency cedar pellet During the tests, we observed that porous alumina more difficult agglomerate than silica sand, because its specific properties. volatile matter from pellets mostly burned in dense when employed, as captured part released fuel pellets. Therefore, temperature higher sand under same experimental...

CO2 reforming of methane was studied by bubbling a CH4/CO2 mixture in molten salt bath alkali-metal carbonate (Na2CO3/K2CO3) containing suspended metal catalyst powder at 1223 K. Ni, Fe, Cu, or W metals, supported on an Al2O3 support, were examined for activity and selectivity. The most active selective the Ni/Al2O3 catalyst. conversion increased with increase W/F ratio (W = weight catalyst, F flow rate mixture). About 70% obtained 0.25 g min cm-3, which H2/CO product gas approximately...
