The energy consumption of manycore architectures is dominated by data movement, which calls for energy-efficient and high-bandwidth interconnects. To overcome the bandwidth limitation electrical interconnects, integrated optics appear as a promising technology. However, it suffers from high power overhead related to low laser efficiency, use techniques methods improve its costs. Besides, approx...
The Zero Emission Coal Alliance (ZECA) is developing an integrated zero emission process that will generate clean energy carriers (electricity or hydrogen) from coal. The process exothermically gasifies coal using hydrogen to produce a methane rich intermediate state. The methane is subsequently reformed using water and a CaO based sorbent. The sorbent supplies the energy needed to drive the re...
موتور استرلینگ به عنوان یک موتور احتراق خارجی، با راندمان نزدیک به راندمان کارنو، گزینه مناسبی جهت استفاده در سیستم های تولید توان با توزیع پراکنده می باشد. در این مطالعه ابتدا تحلیل های ترمودینامیکی مختلفی روی موتور استرلینگ انجام گرفته و سپس تاثیرات دمای منبع گرم، حجم محفظه انبساط، سرعت دورانی موتور، فشار متوسط سیکل و اختلاف فاز پیستون ها بررسی می گردد. با استفاده از روش شبکه عصبی، بهینه سازی...
a set of multicomponent perovskite oxide nanoparticles based on la1-xsrxco1-yfeyo3-δ(lscf) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (lt-sofc) as cathode materials. the precursor materials used in this synthesis were lanthanum nitrate hexahydrate [la(no3)3.6h2o], strontium nitrate [sr(no3)2], cobalt nitrate hexahydrate [co...
Nanocrystallite ceria-doped scandia-stabilized zirconia (1Ce10ScSZ) powders are prepared using a combination of co-precipitation and hydrothermal treatments. Power density of 1.0 W cm(-2) is obtained at 1.6 A cm(-2) and 800 °C due to the drastic reduction of ohmic and polarization resistance in the SOFC cell.
SERS provided by sputtered silver was employed to detect trace amounts of chemical species on SOFC electrodes. Considerable enhancement of Raman signal and lowered detection threshold were shown for coked nickel surfaces, CeO(2) coatings, and cathode materials (LSM and LSCF), suggesting a viable approach to probing electrode degradation and surface catalytic mechanism.
