This concept has been extended to half-Heusler (HH) alloys in the form of entropy engineering by substituting one of the elements with multiple elements or by combining 2 HH alloys to form a double half-Heusler alloy. Here, entropy engineering of double HH Ti₂NiCoSn_0.5Sb_1.5 by the substitution of Ti with Al, Ta, and Zr was studied. Due to their low solubility in Ti, Al and Ta formed Ni-based intermetallic phases. Compositional tuning was performed based on the optimum individual dopant levels of Al, Ta, and Zr. Compositional tuning revealed that the introduction of Ta and Al improved the power factor and lowered thermal conductivity due to the formation of the TaNiCoAl quaternary full Heusler (FH) secondary phase. Zr was completely soluble in the HH alloy, lowering the thermal conductivity at the expense of the power factor. Ti_1.6Ta_0.2Al_0.2NiCoSn_0.5Sb_1.5 with a power factor of 3.83 mW/mK² had a ZT of 0.71 at 823 K, which is higher than those of other double HH alloys. Ti_0.6Ta_0.2Al_0.2ZrNiCoSn_0.5Sb_1.5 also exhibited a low lattice thermal conductivity of 2.19 W/mK at 420 K, which is comparable to that of Hf-substituted HH alloys.

The initial rotating disc electrode benchmarking of the Fe-N-C catalyst's oxygen reduction reaction activity using Nafion in an alkaline electrolyte seems to neglect the restricted oxygen diffusion in the AEIs and is recommended to be complemented by measurements with the same AEI as used in the alkaline exchange membrane fuel cell (AEMFC) testing. Evaluation of the catalyst layer in a gas-diffusion electrode setup offers a way to assess the performance in realistic operating conditions, without the additional complications of device-level water management. Blending of a porous Fe-N-C catalyst with different types of AEI yields catalyst layers with different pore size distributions. The catalyst layer with Piperion retains the highest proportion of the original BET surface area of the Fe-N-C catalyst. The water adsorption capacity is also influenced by the AEI, with Fumion FAA-3 and Piperion having equally high capabilities surpassing Sustainion. Finally, the choice of the membrane influences the ORR performance as well; particularly, the low hydroxide conductivity of Fumion FAA-3 in the room temperature experiments mitigates the ORR performance irrespective of the AEI in the catalyst layer.

Lithium-ion batteries often remain in a static state for extended periods during vehicle applications, particularly in high-temperature conditions, which poses significant challenges to their safety performance. In this content, this work investigates the evolution of overcharge performances and underlying mechanism during high-temperature calendar aging. The findings reveal that overcharge tolerance, represented by thermal runaway triggering temperature and duration time, decreases with aging. Simultaneously, thermal hazards, indicated by maximum temperature and maximum temperature rise rate, also diminish with aging. Multidimensional characterization demonstrates that lithium plating, gas generation, and transition metal dissolution are key failure mechanisms leading to performance degradation. Specifically, the reduced thermal stability of the anode and cathode is identified as the primary cause of the decline in overcharge tolerance.
