The multi-functional aspect of scanning holographic microscopy: a review(Invited Paper)

Recent developments in scanning holographic microscopy that offer the prospects of new quantitative tools and imaging modalities in bio, micro, and nano sciences are reviewed. The versatility of the method is emphasized. Scanning holography can operate in an incoherent mode for fluorescence imaging, in a coherent mode for quantitative phase imaging, or in a tomographic mode for axial sectioning and rejection of the out-of-focus haze. Possible applications are illustrated with examples, and future prospects ...

Chemistry of ethylenimine

The structure of the compounds formed by the oxidative conversions of N-aminoethylenimine (I) was established by the application of IR spectrocopy, PMR, gas-liquid chromatography, and independent syntheses. Basically the reaction proceeds with the formation of ethylideneaminoethylenimine (II); in addition to this, bisaziridine, acetaldazine, and the hydrazone of acetaldehyde are also formed.     

Primitive Illumination Systems for Families of Convex Bodies in the Plane

Let F= {C₁,C₂,...,C} be a family of ndisjoint convex bodies in the plane. We say that a set Vof exterior light sources illuminates F, if for every boundary point of any member of Fthere is a point in Vsuch that is visible from ,i.e. the open line segment joining and is disjoint from F. An illumination system Vis called primitive if no proper subset of Villuminates F. Let p_max(F) denote the maximum number of points forming a primitive illumination system for F, and letp_max(n) denote the minimum of F) taken over all families Fconsisting of ndisjoint convex bodies in the plane. The aim of this paper is to investigate the quantities p_max(F) and p_max(n).     

Reaction of bis(trimethylsiloxy)phosphine with trimethylsilane

Bis(trimethylsilyl) [3-(trimethylsilyl)propyl]phosphonate and trimethylsilyl [3-(trimethylsilyl)propyl]-phosphinate are obtained by the reaction of bis(trimethylsiloxy)phosphine with trimethylallylsilane and converted into [3-(trimethylsilyl)propyl]phosphinic and [3-(trimethylsilyl)propyl]phosphonic acid, respectively, by the reaction with methanol.     

Investigation of silyl-substituted alkylthioacetates by IR and UV spectroscopy,1H and29Si NMR,and mass spectrometry

Conclusions The IR, UV, NMR, and mass spectra of silyl-substituted alkylthioacetates have been investigated. Intramolecular coordination of the carbonyl group with the silicon atom has been shown to exist in molecules of trifluoroaeetylthiomethylsilane in the condensed state and in a polar solvent (acetonitrile).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2224–2228, October, 1985.     

Barriers of syn-anti-transitions of phenyl-β,β-dichlorovinyl ketone 2,4-dinitrophenylhydrazone

Conclusions The rate constants and the barriers for the syn-anti-isomerization of phenyl-,-diehlorovinyl ketone 2,4-dinitrophenylhydrazone were obtained by the direct kinetic method.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1402–1403, June, 1974.
