A joint study of bond nature, atomic mean-square displacements, phonon dispersion curves, Grüneisen parameters, and phonon vibrations to systematically analyze the ZTE mechanisms. The results suggest that the transverse vibrations of the –C≡N− groups are instrumental, particularly due to the involvement of the N atoms and the nature of the Ni–N and Pt–C bonds. Phonon modes with negative Grüneisen parameters at low frequencies play the mainly role to balance the positive thermal expansion from others frequency zone modes to obtain the ZTE behavior.

To this end, Li4SiO4/SiO2 was used as a structural regulator to eliminate the residual lithium and convert the irreversible phase. The Li4SiO4/SiO2 protective coating effectively suppresses the corrosion of the electrolyte by blocking the direct contact between the electrode and the electrolyte, while having a high air stability under the hydrophobic action. In addition, SiO2 has excellent corrosion resistance, which further enhances the cyclic stability of the material. The obtained regenerated NCM material displayed a great capacity of 198.6 mAh g−1 at 0.3 C and long cycling stability (capacity retention of 82.2 % after 250 cycles).

For this reason, gravity assisted drainage method, static drainage method are designed to migrate the water out of the cell. However, even with these methods, the reliability of the water removing from the cell remains questionable. Therefore, this paper introduces a novel water removal method to solve these problems and visualisation techniques were used to a more comprehensive knowledge of water transport mechanisms in dead-ended PEMFCs. A pressure-swing operation is realized by controlling the inlet of PEMFC solenoid valve to remove water and recycle oxygen during purging. The dynamic response characteristics of this system under different current densities, pressure differences, cell temperature and purging intervals are experimentally investigated in detail.

Controllable SnTe-embedded Bi2Te3 nanocomposites can be synthesized with the addition of excessive Sn into Bi2Te3 by tuning the crystallization behavior under proper thermal heating temperature. Notably, the precipitation temperature of Bi2Te3 increases from 473 K for Sn20.9(Bi2Te3)79.1 to 573 K for Sn34.4(Bi2Te3)65.6, expanding the controllable temperature span for the presence of SnTe phase. The second-phase nanoprecipitate SnTe can improve electrical conductivity by competing with the Bi2Te3 phase, achieving an increase of four orders of magnitude at the critical temperature of ∼500 K. Simultaneously, it increases the interfacial energy filtration effect between nanocrystalline grains, decoupling electrical parameters between conductivity and Seebeck coefficient. Consequently, the high power factor of ∼147 μW/mK2 at 650 K for optimized Sn26.6(Bi2Te3)73.4 films can be obtained, which is more than twice that of the pure Bi2Te3 material. Our work demonstrates a new physical mechanism to unravel the complicated structure-property relationship by dual-phase competitive behavior during phase transition.
