Ceramics from zinc oxide nanopowder. Production, structure, properties Fine ceramics (about 2–5 microns) from nanodispersed of zinc oxide powder on hot pressing plant was produced, its properties were investigated. This zinc oxide ceramics can be used as a target for magnetron, electron beam and other methods to create transparent conductive films. In particular, this optical ceramics is a promising alternative to traditional mono crystals in scintillation and laser technology.

The efficiency of thermoelectric current inputs from submicron powders of bismuth telluride alloys for HTS- PTL Promising application of the high-temperature super-conducting conductors (HTS) is their use in the power transmission lines (PTL). Over the last ten years a number of investigations were carried out to assess the feasibility of creating HTS-PTL power lines on AC. The main drawback of such power lines is power losses connected with the reversal of the material with AC. HTS – PTL on DC do not have this drawback, but they require electrical inverters which convert AC to DC and vice versa. It is shown that at the length more than 50 km the efficiency of PTL on DC exceeds this figure for PTL on AC. In addition, PTL on DC have a lower cost, greater resistance to short-circuit, the ability to operate at very large voltages (up to 800 kV).

Electrophysical characteristics of modified carbon nanotubes One of the promising directions of material science and nanotechnologies is creation of carbon nanotubes (CNTs). The results of experimental inves-tigations of the physical and chemical properties of nanopowders of multiwalled CNTs are presented in this article. The possibility of varying the value of electric resistivity by modifying them and by using of CNTs as a filler of polymer composites with a given conductivity is shown.

From Scan to FemtoScan: results of 25 years of scientific activities The emergence of scanning probe microscopy (SPM) coincided with the beginning of the era of personal computers. For the past twenty five years the SPM history has become an era of high technology development which are largely related to the scientific and technological revolution in computer and information technologies. This paper discusses the creation of the first Russian SPM Scan instrument and its subsequent brand new modifications.

TNanotechnologies and acceleration of macro-particles is the thermonuclear problem solution The creation of the fusion power station on inertial thermonuclear fusion is not entirely successful. Heating a solid state target of deuterium and tritium by laser radiation, ion beam or the inertial Z-pinch effect provides a single micro-explosion, but the frequency of such explosions has be large enough and for a station with a capacity of about GW it will be dosens of Hz. It is very difficult to focus the radiation of a large number of sources and place the target to the set point in hundreds parts of the second because there was an explosion equivalent to dusens of kilograms of TNT in the reactor. How long it can take technically to replace the target. Degradation of optical elements under the influence of ionizing radiation has not been solved yet. Unsuccessful attempts to obtain energy from plasma confined by a magnetic field do not contribute to creation of a cost-effective thermonuclear station. There is a need to consider a different approach.

How outstanding inventions are created Almost each inventor wishes to be imprinted in human history. And the main route for this purpose - creation of a pioneer or important invention, which can give rise to a new direction in science and engineering. Whether it is possible to program your success in this matter or at least to define basic directions of further steps? One of good decisions – to use a complex of well known techniques, leading to principally new results. It is expedient to consider such approach by an example of scanning probe microscopy.
