Learning the Physics and Chemistry of Surfaces via Machine Vision and Deep Data Analysis

Ziatdinov M., Maksov A., Kalinin S.V., Oak Ridge National Laboratory, US

The last decade has witnessed an enormous increase in the size and quality of datasets produced by microscopic and spectroscopic experimental techniques. Particularly, the recent advances in scanning transmission electron and scanning probe microscopies have [...]

G-Mode KPFM: Bringing Kelvin probe force microscopy into the information age

Collins L., Kalinin S., Jesse S., Oak Ridge National Laboratory, US

Fundamental mechanisms of energy storage, corrosion, sensing, and multiple biological functionalities are directly coupled to electrical processes and ionic dynamics at both the solid-gas and solid-liquid interfaces. In many cases, these processes are spatially inhomogeneous [...]

Atomic-level characterization of metal/oxide interfaces (Ti, Fe, Ni, Ag, Au/Al2O3, MgO, TiO2): a background for nanomaterial design for catalysis to photonics

Khubezhov S.A., Silaev I.V., Bliev A.P., Kibizov D.D., Grigorkina G.S., Kozyrev E.N., Askerov R.O., Goncharov I.N., Sekiba D., Ogura S., Fukutani K., Magkoev T.T., North Ossetian State University, RU

Corresponding author, e-mail: t_magkoev@mail.ru (Tamerlan Magkoev) Metal/oxide systems are widely used in different application fields, such as heterogeneous catalysis, nanoelectronics, sensing techniques, optics, photonics, etc. [1]. Despite of a very extensive research in this field, [...]

Polymerized Ionic Liquid Films in Strong Electric Fields: Ion Transport and Nanopatterning

Kumar R., Bocharova V., Strelcov E., Tselev A., Collins L., Kravchenko I.I., Berdzinski S., Strehmel V., Ovchinnikova O.S., Minutolo J.A., Sangoro J.R., Agapov A.L., Kisliuk A., Soko A.P., Oak Ridge National Laboratory, US

The current work represents an important step in a search for novel materials and experimental techniques that would allow for controllable and inexpensive methods of surface patterning with nanoscale resolution. The novelty of the nanopatterning [...]

Quantifying and enforcing the two-dimensional symmetry of scanning probe microscopy images of periodic objects

Moeck P., Moon Jr. B., Sánchez E., Abdel-Hafiez M., Hietschold M., Portland State University, US

The defining features of a scanning probe microscope are a very fine probe that is scanned in two dimensions (2D), in very fine steps, very close to the surface of a sample, and a probe-sample [...]

Characterization of Cellulose Nanocrystals by SPM

Lahiji R.R., Reifenberger R., Moon R.J., Rudie A., Purdue University, US

Cellulose is the world’s most abundant biopolymer and is present in virtually all plants. Its main function is to act as a reinforcement material. Cellulose is a linear chain of ringed glucose monomers ((C6H10O5)n; n=10 [...]
