By changing the calcination time, moderate grain boundary density and the Cu + /Cu 0 ratio in catalysts can be controlled, leading to a large number of active sites and low interfacial charge transfer resistance.

Growth and Grain Boundaries in 2D Materials ACS Nano

WebApr 15, 2024 · Grain boundaries determine physical properties of bulk materials including ductility, diffusivity, and electrical conductivity. However, the role of grain boundaries in nanostructures and nanoparticles is much less understood, despite the wide application of nanoparticles in nanophotonics, nanoelectronics, and heterogeneous catalysis. In electrostatics, a common problem is to find a function which describes the electric potential of a given region. If the region does not contain charge, the potential must be a solution to Laplace's equation (a so-called harmonic function). The boundary conditions in this case are the Interface conditions for electromagnetic fields. If there is no current density in the region, it is also possible to define a magnetic scalar potential using a similar procedure. can people walk
