14.Other methods for the synthesis of exohedral fullerene hydrides are also described.

15.Considerable attention is paid to the state of hydrogen in solid fullerene hydrides.

16.The structures and reactivities of fullerene hydrides are considered.

17.Hydrogen sorption and storage in new carbon materials are surveyed.

18.The sorption of hydrogen by single-walled carbon nanotubes, carbon nanofibres and their modifications doped with alkali metals are discussed.

19.Hydrogen storage in nanostructured graphite is analysed.

20.It is noted that the mechanism of high sorption of hydrogen by carbon

nanomaterials is still obscure.

21.Several mechanisms have been proposed.

22.The results of theoretical calculations of the hydrogen capacity of carbon nanomaterials in terms of various theoretical models are presented.

23.Fixed voltage is applied to the needle that scans the surface of an object and to the object itself.

24.This current is sustained at a constant value with the aid of a servo system

which either lifts or lowers the scanner depending on the relief of the surface.

25.By and large, they are used in high (fine) vacuum.

26.Depending on what kind of operation is carried out in particular and on the size of an object, the scanner either moves this object at a desired pace or controls the cantilever's movements.

27.The latest models are equipped with a pitch engine to move the object under the microscope back and forth.

28.Such needles are fastened on beams which, in their turn, are made to preassigned thickness.

29.For instance, those with a current-conducting surface are used for measuring the relative distribution of surface resistance and capacity.

30.Conductor probes supplied with dielectric coating are employed for determining the distribution of subsurface magnetic fields and capacity.

31.They are needed for research in narrow fields.

32.Numerous examples are given.

33.Today these disks are made by die-stamping.

34.The conference was attended by scientists from Moscow Kiev and Minsk.

35. Polished silicon plates have been mainly used so far for the production of integrated circuits.

34. But with the current transition to submicronic and nanometer levels preference is being given to what are called epitaxial structures.

36.What is more, methods have been developed of producing such films with preset characteristics.

37.The attention of experts has also been attracted by yet one more modification of this remarkable material - porous silicon.

38.What is more, methods have been developed of producing such films with preset characteristics.

40.The attention of experts has also been attracted by yet one more modification of this remarkable material - porous silicon.

41.When some of the associated problems are resolved the new material will have a future as light emitter in the visible band.

42.In that case the generated emission of 1.54 Mkm is practically not absorbed by silicon and matches the maximum transparency "window" of optical waveguides of quartz glass.

43.This area of research is believed to have taken its start back in the 18th century.

44.This knowledge is now successfully applied in power engineering.

45.Geochemistry has been fully submitted to geology, and biology has been "blessed" with the now rapidly progressing biochemistry.

46.At the same time a clear picture was obtained of the structure of matter - the molecule and the chemical bonds therein.

47.For this discovery the Russian scientist and his British colleague Sir Cyril Hinshelwood (1897-1967) were honoured with a Nobel Prize in 1956.

48.V. Belousov discovered the first oscillating time-dependent chemical reactions which had been previously regarded as impossible in principle.

49.Considerable achievements of fundamental chemistry have also been observed in the field of directional or controlled, fine organic synthesis.

50.This is also promoted by the fact that the chemical analysis theory has now taken body and form.

51.Significant progress has also been made in the development of applied chemistry.

32

52.Until today this base was oil and petroleum-processing products, and these will soon be replaced with natural gas and methane.

53.20 years later the find was studied for the first time by a team of German chemists.

54.This was followed by a report on a discredit of the very name "lavrovite".

55.The mineral was given the name of "kalininite".

56.The third of the newly discovered mineral also features an unusual composition – some of its chromium is replaced will antimony (such compound was found for the first time).
