of many first and second row transition metals in acidic conditions during the ORR, further alloy-based routes towards precious-metal elimination at low pH are limited7,8,9. In contrast, anion exchange membrane FCs (AEMFCs) offer a higher pH regime, enabling the stable use of less-expensive...
As seen for 3 nm-sized nanoparticles (NPs) anchored on well-defined rutile tita- nia nanorods, Au and Pd atoms form a solid-solution alloy, whilst Au and Rh atoms segregate into single-phase domains within the NPs15. Nevertheless, in both cases the interaction of the active metal (Pd,...

Effectively designing the coordination environment of metal atoms in single-atom catalysts to enhance the oxygen reduction reaction (ORR) performance is challenging. Herein, a strategy for regulating the electronic structure of double-site Mn2-N6 by axial traction of Mn cluster is presented. The atomi...
With the advent of electrospray ionisation (ESI) and matrix-assisted laser desorption ionisation (MALDI), mass spectrometry (MS) is now routinely used to establish the molecular formulae of gold nanoclusters (AuNCs). ESI-MS has been used to monitor the s
one great advantage of Na batteries is certainly the feasible replacement of copper with aluminium current collectors since Na does not alloy with this metal.12 This could represent substantial cost and weight savings for batteries.11,13 In layered NaxMO2, Na cations can be accommodated in trigona...
In the process of studying the bond mechanism of metals or alloys, the primary consideration is the electronic structure between atoms. We utilize it to describe the structural stability of the FeTi alloy at high pressure. To study the change in the total density of states (TDOS) at high pr...
Xue et al. [57] produced their auxetic structures made of Al and its alloy by 3D printing combined with the molten metal infiltration technique. Under the compressive mechanical loading until about 50% strain, the stress–strain flow curves of (auxetic) specimens made of pure Al and 6063 Al...
