ascribing to the increase of density of states near the Fermi level and electron charge transfer between the components. The non-covalent interaction leads to polarons in the Co4+-enriched structure, which facilitates the deprotonation of the surface bridge OH*species and subsequently the formation...
Doping with pyridinic nitrogen atoms is known as an effective strategy to improve the activity of carbon-based catalysts for the oxygen reduction reaction. However, pyridinic nitrogen atoms prefer to occupy at the edge or defect sites of carbon materials

3d, e indicate that the bright dot in Fig. 3c at site 1 is corresponding to Mg–Nx moieties. The Energy dispersive X-ray spectroscopy (EDS) images in Supplementary Fig. 17f shows that the elements of Mg, N, and C are uniformly distributed in Mg–N–C. The Mg content in Mg–N–C...
The ring-opening curing reaction of epoxy with amine group can form a strong covalent bond between the two channels. Curing time was intentionally prolonged to 24 h to ensure bond formation. Stop flow lithography set-up. The set-up for stop flow lithography (SFL) uses pressure provided by...

This system has two main attributes: generation of a short-duration excitation beam and subsequent detection of the phosphorescent signal emitted by the primary sensor (free or natural response). Figure 2. (a) Block diagram of the built instrument and (b) physical setup. Pulsed Light Source ...
(slopes) of potential to the DO concentration of CF and CF500 were 0.0016 and 0.0079, respectively; the response to DO concentration increased five-fold in CF500.Figure 3c shows a schematic diagram of the increase in potential response with capacitance. In this study, ORP measured by CF500 ...
The in situ HERFD and XAS data revealed that Fe3+, located in the octahedral sites with short Fe-O bond distances, was triggered by the edge-sharing with the surrounding [NiO6] octahedra. This explanation was reinforced by the density function theory with Hubbard U (DFT+U) calculations. ...
Therefore, the combined vacuum system with an ejector and liquid ring pump was adopted. A diagram of the proposed system is shown in Figure 1. Figure 1. Ejector/liquid ring pump vacuum subcooling system. The liquid oxygen vacuum process is shown in Figure 1. At the beginning of the ...
