Weathering processes and infiltration metasomatic processes in the weathering crusts hyperbasite arrays have a positive effect on the accumulation of rare earth elements. The content of rare earth elements is steadily increasing bottom-up on the profile of weathering. Metasomatic upper profile characterized by a high content of rare earth elements, which leads to the appearance of rare earth elements phosphate mineral phase – xenotime found in this laterite for the first time. The composition of the rare earth elements in incorporating their metasomatic and minerals demonstrates chondritic distribution.

Materials of calculation of solubility of aluminum hydroxide in the system Na2O – K2O – Al2O3 – H2O, by data of the solubility in the private sections of this system for a wide range of compositions aluminate solutions by the content of alkaline components are presented. It is shown that the solubility of aluminum hydroxide in the range of concentration of alkaline components from 1,29 mol/l to 1,94 mol/l is a linear function of the mol fraction of one of them. The results of experimental researches on decomposition of aluminate solutions are given. Significant increase of the degree of decomposition of aluminate solutions in per cents of the theoretical values with growth of mol fraction of K2O in a mixture of alkaline components has been established.

Concerning the possibility of an effective hadfield's steel cold-work hardening in the working conditions of the lining of spherical mills
Taking a grinding of coal ball mill (type: BTM 400/800) operating without rocks as an example it is shown that a bombardment of the armour by grinding bodies made of steel 110G13L directly is capable to raise its hardness from 200 to 320HB at the depth of the cold-hardened layer up to 6,7 mm that will approximately 2 times increase its firmness to an abrasion. The time needed for the realization of an effective bombardment is 11 minutes, the period between strengthening cold – work hardenings is 25 days.

The paper presents a number of experimental techniques for detecting in amorphous tantalum oxide films structural defects, which accelerate film destruction processes in a strong electric field and thus are potentially dangerous under prolonged thermoelectric stresses applied to capacitor structures. It is shown that the anomalous frequency dependence of dielectric losses and increase of the leakage current over time can identify potentially unreliable capacitors.

Heritage of the brick or information embedded in the brick from historical viewpoint
- Authors:
- E. M. Kuritsyn
Brick is the oldest building material except stone and wood. A cob brick with added sliced straw served as a constructional material in many ancient countries. Using of burnt brick is also dated from ancient times (it was utilized in Egypt, Mesopotamia and Ancient Rome in 3-2 century B.C.). First brick constructions in Russia (fortified walls, temples, towers and stoves) appeared in IV century. Then, in XI-XII centuries, thin and very heavy plates of different sizes («plinphes») were used and in XV century a modern bar-shaped brick has appeared. That time is associated with the flourishing of «brick craft». In 1475 the architect Aristotle Fioravanti was invited into Moscow from Italy to build the Kremlin. The paper is devoted to the history of brick as an ancient building material and to the birth of brick collection.

The method of local anisotropic plasma has been developed. The mathematical apparatus of the method for rapid analysis of the degree of anisotropy electron distribution function, as one of the main characteristics of anisotropic plasma has been proposed. It has been demonstrated that the degree of anisotropy of the plasma can be determined only by the form of the IU curve (the second derivative of probe current to the probe potential). The possibilities of the method in area of reconstruction of the full distribution function have been illustrated.

Nanotechnologies in modern plasma energetics
- Authors:
- A. S. Mustafaev
- K. I. Sidorova
- M. A. Mamelkina
Fundamental research in the field of plasma energetics provides a new opportunity to achieve high efficiency of thermionic converters (TIC). The interelectrode gap of such TICs contains the condensate of excited states (CES), consisting of up to 1000 excited Cs atoms in the form of a plasma crystal (Rydberg matter). In a laboratory TIC with Cs CES the efficiency of ~25 % was registered by emitter’s tem- perature ТЕ ~1600 К and collector’s temperature ТС ~700 К. A unique combination of low TE and high efficiency of the system provides a prospect to implement such systems in small nuclear energetics. The results were obtained with SSC RF – Institute for Physics and Power Engineering (Obninsk).

It is demonstrated that a diffusion path confinement for characteristic electrons provides a possibility to measure electrons energy distribution function and to find characteristic spectra of species at high (up to atmospheric) gas pressure. Simple micro-plasma CES detector of two plane parallel electrode configuration with current-voltage measurement in afterglow of helium glow discharge may be designed to operate at a high gas pressure up to atmospheric one. Experimental electron energy spectra of pair He metastables collisions in dependence of interelectrode gap are discussed.

Physical processes that lead to the emergence of large forces of attraction between bodies, joined by anodic bonding technology result from the large electric fields strengths at the contact interface. Nondestructive method of monitoring the strength of obtained conductor-to ionic dielectric anodic bonding seals is based on the relationship between the dependence of current versus time flowing in the formation of seals and the strength of the resulting seals. Theoretically justified a new technological method for nondestructive testing of high-quality anodic bonding seals. The results obtained are confirmed experimentally.
