In this paper, we demonstrate that the electric double layer capacitance of the PEMFC cathodes (geometric active area size of 43.6 cm2) increases linearly from 268 K up to 333 K; and using this information, it is possible to determine the catalyst temperature accurately within this temperature ...
Hence, in order to reduce the overlap between the two classes of generated molecules, we only take the top 20% fragments with the smallest attributions less than 0 as the negative fragments, and only the top 20% fragments with the largest attributions higher than 0 as the positive fragments....

This paper addresses the study of a pillow lava interbedded with Late Albian-Early Cenomanian sediments that crops out in Armintza (Bizkaia, Northern Spain). The lava flow is an alkaline basalt with abundant macrocrysts of clinopyroxene, kaersutite, Ca-rich plagioclase (50-86% An) and ilmeni...

As we mentioned previously in this paper, when in 1953, Miller performed his synthesis of amino acids with an electric discharge in a mixture of gases, it was fully justified to consider this synthesis as a prebiotic experiment. By using the life index concept introduced in the previous ...
(7), we find that this single-particle state violates the inequality since Nocc = 2 and is many-body fragile. Adiabatically adding interactions cannot trivialize the state. We generalize the inequality criterion of Eq. (7) to all wallpaper groups in Supplementary Note 3, obtaining ...
The experimental results indicate that CLF depends on the molecular-scale heterogeneity of the SAM surface: most heterogeneous intermediate-coverage SAMs have higher friction than low- and high-coverage SAMs. However, it is not clear based on the experiments why we get these CLF values at each co...
