We present fast sintering for silver (Ag) nanoparticle (NP) and flake layers printed using roll-to-roll (R2R) gravure printing. An infrared (IR) sintering module was applied to an R2R system to shorten the sintering duration of an R2R gravure-printed Ag layer. IR sintering of the conductive layer was improved by optimising the process condition. After printing of the Ag NP and Ag flake layers, ...

This paper describes thermoelectric properties of La-doped SrTiO3 prepared by using a combination of combustion synthesis (CS) with post spark plasma sintering (SPS), on which effects of sintering temperature were mainly examined. In experimental, combustion-synthesized (CSed) samples (Sr1 xLaxTiO3, x 1⁄4 0:08) were spark-plasma-sintered (SPSed) at temperatures from 1513 to 1663K and the thermo...

the fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. porous nanocrystalline strontium-doped lanthanum manganite la0.8sr0.2mno3 (lsm) cathode materials were prepared by mechanochemical route in various grinding times. carbon black was employed to produce pores. the formation of lsm single phase was studied by x-ray ...

in order to understand the impact of layer-wise scanning direction in the selective laser sintering process, test coupons were manufactured for mechanical testing from duraform™ polyamide powder. the effects of laser energy density, varying between 0.003 and 0.024 j/mm 2 were examined in test specimens rotated 90º through the z axis. sls machines do not always facilitate ‘cross-hatching’ of lay...
