Structural phase transition in surface layer of metals

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2023
In the article a review of various phenomena on the surface of pure metals is given: the occurrence of the sur- face states of Tamm and Shockley; quantum size effects; electric double layer, the work function of electrons from a metal.

Surface layers of bacteria [PDF]

open access: yesMicrobiological 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.

Primary nanocracks in nitrides, borides, and carbides of refractory metals

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2023
A model is proposed that can be used to calculate the length of a nanocrack in a solid body. The nanocrack length in nitrides, borides, and carbides of refractory metals turned out to be in the range ...

Interaction between coherent structures and surface temperature and its effect on ground heat flux in an unstably stratified boundary layer [PDF]

open access: yes, 2013
Surface layer plumes, thermals, downdrafts and roll vortices are the most prominent coherent structures in an unstably stratified boundary layer. They contribute most of the temperature and vertical velocity variance, and their time scales increase with ...

Ion-implantation induced anomalous surface amorphization in silicon [PDF]

open access: yes, 1994
Spectroscopic ellipsometry (SE), high-depth-resolution Rutherford backscattering (RBS) and channeling have been used to examine the surface damage formed by room temperature N and B implantation into silicon.

Self-Polarization in PbTiO3 Crystals Induced by Chemical Inhomogeneity in the Surface Layer

open access: yesCrystals, 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.
