Surface layers of bacteria [PDF]
Microbiological Reviews, 1991 Since bacteria are so small, microscopy has traditionally been used to study them as individual cells. To this end, electron microscopy has been a most powerful tool for studying bacterial surfaces; the viewing of macromolecular arrangements of some surfaces is now possible.

Self-Polarization in PbTiO3 Crystals Induced by Chemical Inhomogeneity in the Surface Layer
Crystals, 2023 We study the so-called self-polarization phenomenon in single, electroded PbTiO3 crystals. In this case, near the electrodes, surface layers are formed with a chemically modified perovskite structure.
