The 7th preprint edition of the research article “Fabrication methods of the polygonal masonry of large tightly-fitted stone blocks with curved surface interfaces in megalithic structures of Peru” written by R. V. Lapshin has been posted at the Preprints.org repository (category: engineering.mechanical engineering). The article describes several methods that probably were used for building the most complicated type of the polygonal masonry found
in Peru. This masonry consists of large stone blocks weighing from several hundred kilograms to several
tons fitted close to each other almost without a gap between complicated curved surfaces of large area. The techniques under discussion are based on the use of a reduced clay model, 3D-pantograph, topography translator, and clay/gypsum replicas. The article shows that the Fortress Sacsayhuaman can be considered as an early star fortress that survived to our time. Since the polygonal structures in Peru, the polygonal Face Towers and polygonal bas-reliefs in Cambodia, symmetrical statues of pharaohs in Egypt are based on the same construction technologies, working methods, tools and technical contrivances, we can conclude with a high probability that all these monuments were created by the same group of architects, sculptors, and builders, and could not have appeared before the 17th century

- June 2020 – The research article “An improved parametric model for hysteresis loop approximation” written by R. V. Lapshin has been published in the Review of Scientific Instruments journal. The developed model enables building smooth, piecewise-linear, hybrid, minor, mirror-reflected, inverse, reverse, double and triple loops. The usage of the phase shifts Δα1, Δα2, Δα3 and a number of other transformations which are changing the loop tilt and curvature, let us reduce the hysteresis loop approximation error by several times. As a result, the average relative approximation error of the improved model does not exceed 1%. Since the generating function x(α) can be easily represented in the form of a frequency spectrum, hysteresis loops of a custom shape, tilt and curvature can be synthesized by changing the amplitude and phase of harmonic components and by adding/excluding harmonic components with certain values of amplitude and phase. It was proven in the article that the area of a smooth loop is defined by the amplitude and the phase of the 1st harmonic only; the other harmonics of the spectral expansion of the generating function x(α) do not affect the area anyway. A general formula has been derived for building piecewise-linear hysteresis loops of Play and Non-ideal Relay types as well as their numerous variations widely used in simplified models of hysteresis phenomena. In addition, several practical examples of composition/decomposition of the piecewise-linear hysteresis loops have been considered. In particular, it was proven that the detection of Play-Play-Play, Play-Relay-Play or shifted loops during physical measurements may indicate the simultaneous existence of two separate hysteresis processes superimposed on each other. To simplify the construction, analysis, and identification of the hysteresis loops under consideration, the article is accompanied with a voluminous supplementary material in the form of Mathcad worksheets. This supporting material will allow anyone to quickly find the suitable hysteresis loop description specific for his particular problem. Learn more

- October 2018 – The research article “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Real mode” written by R. V. Lapshin has been published in the Applied Surface Science journal. This article completes the series of three articles dedicated to the FOS-based distributed calibration. In the first article “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Approach description” (R. V. Lapshin, Applied Surface Science, vol. 359, pp. 629-636, 2015) of the series, the suggested calibration procedure has been described in detail and also the working formulae have been derived for correction of the scan of an arbitrary surface. The second article “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Virtual mode” (R. V. Lapshin, Applied Surface Science, vol. 378, pp. 530-539, 2016) of the series is devoted to the virtual mode of the distributed calibration. The virtual mode implies that, instead of measurement of the real surface of a standard, the calibration program performs the “measurement” of an image of the standard surface, which has been obtained earlier during conventional scanning. The virtual mode is intended for simulation of calibration process and validation of analytical solutions found in the first article of the series. The real mode being the subject of the present investigation implies that the distributed calibration of the scanner is performed by graphite crystal lattice in real time. The real mode permits to acquire the calibration database (CDB) that completely characterizes the piezoscanner of the microscope in use. The developed method of distributed calibration is one more component of the feature-oriented scanning (FOS) methodology. Learn more

- September 2016 – The artwork “Organ pipes” created by R. V. Lapshin has been selected for incorporation into the MoonArk. The MoonArk is an artistically designed chambers enclosing platinum-etched sapphire disks containing Earth’s art, architecture, design, music, drama, ballet, poetry, sciences, humanities, and technologies. Chamber 3, the Moon contains 93 nano artworks representing the very smallest scale that humans are expressing meaning through art. The MoonArk is expected to travel to the Moon aboard a lunar lander. The launch of Space X Falcon 9 rocket from Cape Kennedy with Astrobotic Robotic Lunar mission aboard is scheduled for late 2019. When the lunar mission will be finished, it is intended that the MoonArk will remain on the Moon as an enduring time capsule, which will exist there for potentially billions of years. The MoonArk has been designed and manufactured at the School of Design of the Carnegie Mellon University. The artwork “Organ pipes” was first exhibited in 2012 at the NanoArt 2012, an international contest among scientific pictures representing scenic views of the nanoworld. The description of the box-shaped graphene (BSG) nanostructure used in the collage “Organ pipes” was recently published in the January issue of the Applied Surface Science journal.

- August 2016 – The research article “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Virtual mode” written by R. V. Lapshin has been published in the Applied Surface Science journal. This article describes a virtual mode of the method of distributed calibration of a probe microscope scanner. In the virtual mode, instead of measurement of a real surface of the standard, the calibration program makes a surface image “measurement” of the standard, which was obtained earlier using conventional raster scanning. The application of the virtual mode permits simulating the process of distributed calibration as well as performing detailed analysis of raster distortions occurring in both conventional and counter surface scanning. The virtual calibration makes possible automatic characterization of a surface by the method of scanning probe microscopy (SPM). The developed method is another component of the feature-oriented scanning (FOS) methodology. Learn more
- May 2016 – The report “Productive drift-insensitive distributed calibration of probe microscope scanner in nanometer range” prepared by Dr. R. V. Lapshin has been presented at the XXVI Russian Conference on Electron Microscopy (SEM-2016) held in Zelenograd, Russian Federation. The conference was organized by the Russian Academy of Sciences. In comparison with the approach applied earlier, the suggested method of distributed calibration provides a much higher performance since for each “fixed” position of Z manipulator, it reduces the problem to calibration in only three points of the field of the XY scanner. According to the experience of the practical application of this method, it is sufficient to conduct calibration for five approximately equidistant fixed positions of Z manipulator. Thus, it is required to implement calibration in 15 points of scanner space in all. Learn more

- December 2015 – The research article “Drift-insensitive distributed calibration of probe microscope scanner in nanometer range: Approach description” written by R. V. Lapshin has been published in the Applied Surface Science journal. The article describes a method of distributed calibration of a probe microscope scanner. The method of distributed calibration consists in a search for a net of local calibration coefficients in the process of automatic measurement of a standard surface, whereby each point of the movement space of the scanner can be defined by a unique set of scale factors. To eliminate the negative influence of thermal drift and creep on the distributed calibration results, the following methods are used: feature-oriented scanning (FOS), feature-oriented positioning (FOP), counter-scanned images (CSI). The lattice constant of a crystal is used as a nature length standard of nanometer range. The method may be used with any scanning probe instrument. Learn more

- June 2015 – The report “Periodic changes in lateral sizes of unit cells at STM images of pyrolytic graphite” prepared by Dr. R. V. Lapshin has been presented at the XIX Russian Symposium on Scanning Electron Microscopy and Analytical Methods of Investigation of Solids (SEM-2015) held in Chernogolovka, Russian Federation. The conference was organized by the Russian Academy of Sciences. Periodic changes in lateral sizes of unit cells of highly oriented pyrolytic graphite (HOPG) are detected along the “slow” scan direction by “oscillations” of local calibration coefficient (LCC) Ky. LCC Ky has been determined by STM image of HOPG during the virtual distributed calibration. The distributed calibration is carried out by applying the methods of feature-oriented scanning (FOS). The oscillations are caused by beatings (moiré) originating from a superposition of the periodical line structure of the raster with a periodical structure of atomic surface topography. Application areas of the work: (1) Detection and elimination of low contrast beatings (moiré) from STM images; (2) Detection of ultra-small mechanical, thermal, etc. strains in crystals; (3) Accurate determination of lattice constants;
(4) Determination of working scanning parameters (bias voltage and tunneling current) at which the force lateral action of a tip upon a surface is minimal. Learn more

- October 2009 – “Autonomous operation of scanning probe microscope for space research”, News, Nanotechweb.org – a community website from
IOP Publishing. A scanning probe microscope (SPM) mounted on board a spacecraft allows for the study of various surfaces at micrometer to nanometer scales. The SPM application in extraterrestrial research is rather promising in that it is a lightweight, compact, and reliable device that supports multiple measurement modes and has low power consumption and high spatial resolution. Thus, the SPM can be used for the study of regolith samples, rocks, minerals, space debris, and micrometeoroids, and can aid in the search for traces of extraterrestrial forms of life. It will also support investigations of the properties of materials, crystal growth, and biomolecular reactions, and help to implement nanotechnological operations in microgravity conditions. To reach these and other goals, the method of feature-oriented scanning (FOS) was suggested in the Solid Nanotechnology Laboratory of the Institute of Physical Problems … Full story. Further reading
- October 2009 – To meet a steady demand from Russian speaking audience for a simple model approximating hysteresis loops, the Russian translation of the paper “Analytical model for the approximation of hysteresis loop and its application to the scanning tunneling microscope” (R.

- October 2009 – “SPM in space”, Nano Digest, Journal of Russian Nanotechnologies: To obtain the adequate image of surface topography, Russian scientist Rostislav Lapshin from the Institute of Physical Problems (Zelenograd, Moscow) suggested a new approach called feature-oriented scanning (FOS). Applying a real-time surface recognition, counter movements, and some other techniques, repeated scanning of small neighborhoods of surface features located in the vicinity of each other are carried out. After that, the searched for topography image, free of noises and distortions, is assembled from the acquired fragments. In the method suggested, topography features of a surface are used as the reference points.
FOS method provides the measurement precision of lattice constants and crystallographic directions increased by orders in comparison with the conventional scanning. The method provides accurately localized tunneling and atomic-force spectroscopy measurements with high signal-to-noise ratio. Moreover, according to the author of the method, the feature-oriented scanning makes it possible to perform “delicate” manipulations with separate nanoparticles, molecules or even atoms at room temperature.
The analysis carried out at the Solid Nanotechnology Laboratory, where the scientist works, showed that the method of feature-oriented scanning that had proved successful in Earth conditions may also help solve a number of problems of using a scanning probe microscope in space – at a near-Earth station or for planet research. The point is that beside much higher measurement precision and spatial resolution, FOS permits to notably decrease the SPM sensitivity to temperature variations. Furthermore, the SPM under feature-oriented scanning control becomes a free-running instrument able of self-testing, self-adjusting and self-calibration. This story in Russian. Further reading
