AFM holds a strong positions in scientific research as is used as a routine analytical tool for physical properties characterization with high spatial resolution down to atomic level. Solver Nano is the best choice for scientists who are need a single instrument that is an affordable, robust, user-friendly and professional tool.


Why is nanotechnology interesting for education?

Cutting edge achievements in science and most successful R&D projects in commercialization are on an interdisciplinary level, combining physics – chemistry –biology - mathematics – engineering – technology - IT. The earliest, widespread description of nanotechnology refers to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products. Proceeding further down to atomic scale, where no border between the scientific disciplines exist and all of them are essential for developers and scientists to understand the technological processes.

Thus using this interdisciplinary approach to the education of students provides a very effective integration and coaches graduate students to fit into an innovative national economy. Scientific projects (school science, pre- college science and etc.) allow to cope with interdisciplinary connections, develop an interdisciplinary approach, form systematically scientific thinking and learn more about modern problems of physics, chemistry, biology and nanotechnology. This is the one of the mission of STEM centers.

Laboratory work of students speciality “Nanomaterials”.

In the new scientific world of nanotechnology a widespread opinion persist that there are two important modern developments: the atomic force microscope (AFM) and the scanning tunnel microscopy (STM). Those are the instruments that have launched nanotechnology due to the fact that scanning probe microscopes are not limited by the wavelength of sound or light and can achieve high resolution results under a variety of environmental conditions..

SOLVER Nano is enabled for teaching principles of scanning probe microscopy and acquiring skills for studying nanoobjects and microstructures. Students can also perform all modern AFM and STM techniques with SOLVER Nano:

In Air: AFM (contact and intermittent contact), AFM spectroscopy, AFM lithography (force, current, voltage), Lateral Force Microscopy, Force Modulation Microscopy, Spreading Resistance Imaging, Piezoresponce Force Microscopy and Switching Spectroscopy, EFM, Kelvin Probe Force Microscopy, MFM, STM (microscopy, spectroscopy, lithography).
In liquid: Contact and Amplitude Modulation AFM, AFM Spectroscopy, AFM Force Lithography, Lateral Force Microscopy.

SOLVER Nano for education provides complete didactic materials for different skill levels of young aspiring scientists.
Basic level: to demonstrate various phenomena and develop skills to work on modern equipment.
Advanced level: designed for advanced studies with higher skilled students to provide insights on composite nature of modern research and interdisciplinary connections.
Research level: performed individually. Example are given on actual problems to demonstrate the structure of scientific research, form skills of designing and performing experiments, work with scientific advisers – tutors and prepare to engage in independent research.
