and direct hydrazine fuel cell (“DHFC”), each have high reversible potentials and can delivery higher output power density. DFAFC has a reversible potential of 1.48 V and output power density of >300 mW/cm2, but needs heavy loading of Pt, Pd catalysts (e.g., >5.0 ...
Nanofluid HED fuels are further introduced as an alternative way to increase the energy density of liquid fuels by adding energetic nanoparticles. Hypergolic energetic ionic liquids are then summarized as a special alternative for toxic and hazardous hydrazine. Finally we will emphasize the problems ...
Compared to the bare Si nanowire photocathode, the overpotential maintaining a photocurrent density of 10 mA cm−2 for the optimized p-Si/n-CdS core/shell nanowire heterojunction photocathode under AM 1.5G illumination is reduced by 0.93 V, and simultaneously the saturated photocurrent density is ...
Harvesting energy from the ambient is a promising approach to fulfil decentralized energy demands and facilitate the transition to low-carbon economy. Moisture-sorption-based energy harvesting (MSEH) is a promising strategy for obtaining heat, cold and e
An integrated high-throughput robotic platform and active learning approach for accelerated discovery of optimal electrolyte formulations Solubility determines energy density in redox flow batteries. Here, authors combine automated experiments with machine learning to efficiently identify solvents that significantly...
At this time, energy density of the laser is required to be about 0.01 to 100 MW/cm2 (preferably, 0.1 to 10 MW/cm2). A scanning rate is set to be about 10 to 2000 cm/sec for irradiation. It is to be noted that, as for a laser using, as a medium, single crystal YAG YVO4,...
The single cell with LBSNM-30YSB air electrode obtains a current density as high as 1188 mA cm−2 at 800 °C and 1.4 V for 70%CO2+30%CO feed gas; this value is 46.5% higher than that of LBSNM under the same conditions. No degradation is observed after the single cell is ...
