- October 2009 – “SPM in space”, Nano Digest, Journal of Nanotechnologies in Russia: 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
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. V. Lapshin, Review of Scientific Instruments, vol. 66, no. 9, pp. 4718-4730, 1995) was prepared and opened to the public at the Publications section
- September 2009 – The Institute for Statistical Studies and Economics of Knowledge at the Higher School of Economics asked Dr. R. V. Lapshin, as an expert in the field, to participate in the survey related to the future development trends of Russian nanotechnologies. The survey was conducted by request of the Russian Corporation of Nanotechnologies. The survey is aimed to better formulate the innovation strategy of the Russian Corporation of Nanotechnologies
- September 2009 – “How to Operate a Scanning Probe Microscope on Board a Space Laboratory or Planet Exploration Rover? – Scientists Suggested an Approach for Remote Control of a Scanning Probe Microscope in Space”, News, European Nanotechnology Gateway: When using a scanning probe microscope (SPM), for instance on board of a near-Earth station or a planet exploration rover, a number of control-related tasks should be solved. A method is required to exclude the operator from the measurement process that would make the microscope operation completely autonomous. To reach this goal, the method of feature-oriented scanning (FOS) was suggested in the Solid Nanotechnology Laboratory of the Institute of Physical Problems. The method had successfully proved its capabilities in conditions of an Earth laboratory, in particular, a great increase in measurement precision and considerable improvement of spatial resolution of the microscope. FOS application under conditions of a space laboratory allows to notably decrease SPM sensitivity to temperature variations. The SPM under FOS control becomes a free-running instrument able of self-testing, self-adjusting and self-calibration, it operates according to the principle “run and forget”. With FOS, the trajectory of the microscope probe movement is not defined beforehand, it is actually being built dynamically during the operation. The behaviour of a microscope probing some unknown sample surface becomes similar to the one of an autonomous rover when it moves across an unfamiliar surface of a planet. Read more
- July 2009 – By request of the Institute for Comparative Social Research, Dr. R. V. Lapshin answered questions, provided his opinion, and suggested possible solutions in the framework of discussion on possible ways improving management and organization of scientific research in Russia. The goal of this sociological study is to determine a place and a role of promising 30-45 years old scientists in the present-day Russian science, outline problems they are confronted with, and decide what measures should be undertaken to stimulate their investigations. The study was ordered by the Public Chamber of Russian Federation
June 2009 – The article “Availability of feature-oriented scanning probe microscopy for remote-controlled measurements on board a space laboratory or planet exploration rover”, by
R. V. Lapshin has been published in journal of Astrobiology (publisher Mary Ann Liebert, Inc.). The article shows how the feature-oriented scanning (FOS) method may help to effectively organize scanning probe microscope (SPM) measurements in space, e. g., on board a near-Earth station or a planet exploration rover. Application of the FOS approach makes an SPM to be an intrinsically less sensitive to temperature variations that is a very important property in space research. Moreover, the SPM under FOS control becomes a self-testing, self-adjusting, and self-calibrating instrument able to operate according to the principle “run and forget”
- May 2009 – The Russian Corporation of Nanotechnologies issued the Expert Certificate to Dr. R. V. Lapshin. The Certificate attests that Dr. R. V. Lapshin meets the qualifying requirements to the experts attracted by the Corporation for conducting scientific, technical, industrial, and technological expertise in nanotechnology and related areas
March 2009 – The artwork “Stonework of ancient Inca” created by R. V. Lapshin has been presented to public at the scientific photo exhibition “Science, this is beautiful!”, section “World that is hidden from us”. Along with other selected artworks, it will be exhibited at the Ministry of Education and Science of Russian Federation, Moscow, at the State Duma of Russian Federation (Russian parliament), Moscow, and at the A. S. Popov Central Museum of Communications, St. Petersburg. The exhibitions are organized by the electronic edition Russian Science and Technology
March 2009 – A report entitled “Smoothing of nanoasperities of poly(methyl methacrylate) film by vacuum ultraviolet” has been presented by Dr. R. V. Lapshin et al. at the XIII International Symposium “Nanophysics and Nanoelectronics” held in Nizhni Novgorod, Russian Federation. The report clearly demonstrates nanometer scale smoothing of poly(methyl methacrylate) (PMMA) surface under ultraviolet radiation in low vacuum environment. The other important phenomenon – PMMA nanostructuring in oxygen RF-plasma was also discussed. The obtained results may be applied in microelectromechanical systems (MEMS) to reduce friction between moving PMMA-elements, in medicine to improve biocompatibility of PMMA-implants, in electron-beam, UV, and X-ray nanolithographies to treat PMMA-resists, in microfluidic devices to facilitate flow through PMMA-microchannels, etc.
