In accordance with the electron configuration of the outer shell (5s25 p2), tin exists in the oxidation states +2 and +4, the latter being more stable. Sn (II) compounds are strong reducing agents. The formation of a thin, strong, nonporous SnO2 film on the surface of tin upon exposure...
(IVA) of the Periodic Table with an atomic number 50 and atomic mass 118.71. Its abbreviated electron configuration is [Kr]4d105s25p2. The atomic radius of nonbound tin is 2.17A. Tin melting point is at 231.93°C (449.474°F) and boiling point is at 2586°C (4686.8°F) (Haynes, ...
Tin [from the Latin wordstannum(Sn)] is a chemical element of Group 14 (previously Group IVA) of the Periodic Table, with atomic number 50 and atomic weight 118.71. Its abbreviated electron configuration is [Kr]4d105s25p2. The melting point of tin is 231.93°C (449.474°F) and the bo...

Full size image X-ray photoelectron spectroscopy (XPS) analysis of Ru NPs/TiN suggests the coexistence of metallic Ru and oxidized Ru (Fig.2a). In the high-resolution Ti 2pXPS spectrum (FigureS7a), Ru NPs/TiN were positively shifted compared to pure TiN, indicating electron transfer from the...
The TiNCl morphology was captured via scanning electron microscopy (SEM, S-4800, 5 kV, Hitachi, Japan), high-resolution transmission electron microscopy (HRTEM, JEM 2100F, 100 kV, JEOL, Japan), and atomic force microscopy (AFM, LabRAM Nano, HORIBA France SAS, France). Electrode ...
Full size image As is well known, SnO2suffers a large volume expansion during the de/lithiation processes1,9,15,33deteriorating the functionality of the electrode and reducing the lifetime of the LIB’s. Other strategy, in order to improve cyclability and life time, is the combination of this...
Full size image To validate this hyprothesis, the electron paramagnetic resonance (EPR) measurement was conducted on TiO2films (Fig.1b), which is able to evidence the OVs directly. An intense unpaired electron signal atg = 2.004 was recorded, suggesting the existence of OVs in TiO2films61...
we explored the effects of CPGCl molecules on the crystal structure and morphology of Sn-Pb perovskite films. Cross-sectional scanning electron microscopy (SEM) images revealed visible changes in the crystal structure of Sn-Pb perovskite films upon the CPGCl addition, as shown in Fig.2a, b. ...
This configuration, which is achieved by the simple addition of a soluble tin precursor such as tin dichloride to the silicon-containing slurry, reduces the SEI-related resistance. In Fig. S7 of the Supplementary Information file we show the same EIS analysis for the anode containing a 9.6% ...
