When white tin cools below 13.2°C, it changes from white form to gray form, commonly called “tin pest” or “tin disease.” The transformation of β-Sn to α-Sn involves a structural distortion with density increase. The process is prolonged and requires long exposure much below 13.2°C...
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...

and long cycling life. Pairing with a commercial cathode material LiNi0.6Mn0.2Co0.2O2, full cells exhibit a gravimetric and volumetric energy density of 590 W h Kg−1and 1,252 W h L−1, respectively, the latter of which doubles that of the cell based on graphite anodes. This...
Furthermore, the substrate roughness [Fig. S4 in the SI] also becomes important for the thinner samples as that can induce disorder in the form of strain or probable weak links leading to PS. In order to examine the effect of disorder on IVCs, we have studied more samples with reduced...

The ground-state configurations of these ions take the form 4dm, with m = 3 − 0. The lowest-lying level of each ground-state manifold is shown in black and is fixed at an energy of 0 eV. The energy "spread'' of an excited configuration is illustrated by a rectangle, ...
they were first bonded to Cu pads using a form of transient liquid phase bonding (TLPB), where the IMC seed crystal remained solid during the TLPB. An immersion tin coating was applied to Cu pads and the nucleant IMC was laid flat with the main facet in the plane of the pad as show...
