The generation of a dislocation spiral and fluctuations in the step velocity on the (101) face of monoclinic lysozyme crystals have been studied by in situ atomic force microscopy (AFM). It is shown that the (101) face grows by the dislocation mechanism and that the steps move via the formation of one-dimensional nuclei. The velocity of a part of the step fluctuates, with the fluctuations increasing proportionally to the fourth-order root of time. In the process of spiral generation, a segment of the step attains a certain critical length and then moves with a constant velocity. Even under constant supersaturation, the fluctuations can give rise to changes in the segment length. The interstep distance in the step echelon also varies. 相似文献

The specific biological activities of a number of ecdysteroids have been investigated in tests on the inhibition of the growth of a culture ofDrosophila melanogaster cells and in experiments on the induction of the metamorphosis of imaginal disks. Some relationships between structure and biological action have been established.Institute of Molecular Genetics, Academy of Sciences of the USSR, Moscow.

Surface structure and the propagation of elementary growth layers over the (010) face of orthorhombic lysozyme crystal is examined at a molecular‐scale resolution by the method of atomic force microscopy (AFM). The steps have a small number of kinks spaced by about 150 growth units. The step motion occurs via successive deposition of rows of growth units. The data obtained are discussed in terms of the model of one‐dimensional nucleation. 相似文献

Studying the mechanisms of steel sheet perforation by the radiation of a continuous-wave fiber laser
G. G. Gladush A. F. Glova V. I. Golovichev S. V. Gvozdev A. G. Krasyukov A. Yu. Lysikov V. K. Rerikh M. D. Taran 《Bulletin of the Russian Academy of Sciences: Physics》2016,80(4):393-396
Aspects of steel sheet perforation are studied experimentally. Calculations show that the mechanisms of thin sheet perforation change as the focal spot size is increased at a constant laser power. If the spot is small, the melt is removed and the film is disrupted by steel boiling in the spot center. With larger spots, the melt is removed by the force of gravity. The hole diameter grows along with the focal spot size and sheet thickness and is reduced upon an increase in laser power. 相似文献
