Figure 1: Electronic structures before and after K dosing for a 30 uc FeSe film on SrTiO 3. Figure 2: Superconducting gaps in K-dosed FeSe films with varied thicknesses and that of K-dosed FeSe 0.93 S ...

The recombination of electron shells in molecules, taking just a few dozen attoseconds (a billionth of a billionth of a second) can now be viewed 'live,' thanks to a new method. The recombination of ...

The shell ultrastructure of the gastropod Cittarium pica (L.) (Recent; Bimini, Bahamas) has been studied by means of correlated light and scanning electron microscopy of growth surfaces, fracture ...

Field investigations of living bivalves of the order Arcoida led to the rediscovery of a contradiction to the longstanding three-fold, three-function concept of bivalve mantle edges. In contrast to ...

Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell. Elements in groups ...
