Polarity-Induced Reactive Wetting: Spreading and Retracting Sessile Water Drops.

Wetting is typically defined by the relative liquid to solid surface tension/energy, which are composed of polar and nonpolar subcontributions. Current studies often assume that they remain invariant, that is, surfaces are wetting-inert. Complex wetting scenarios, such as adaptive or reactive wetting processes, may involve time-dependent variations in interfacial energies. To maximize differences in energetic states, we employ low-energy perfluoroalkyls integrated with high-energy silica-based polar moieties grown on low-energy polydimethylsiloxane. To this end, we tune the hydrophilic-like wettability on these perfluoroalkyl-silica-polydimethylsiloxane surfaces. Drop contact behaviors range from invariantly hydrophobic at ca. 110° to rapidly spreading at ca. 0° within 5 s. Unintuitively, these vapor-grown surfaces transit toward greater hydrophilicity with increasing perfluoroalkyl deposition. Notably, this occurs as sequential silica-and-perfluoroalkyl deposition also leaves behind embedded polar moieties. We highlight how surfaces having such chemical heterogeneity are inherently wetting-reactive. By creating an abrupt wetting transition composed of reactive and inert domains, we introduce spatial dependency. Drops contacting the transition spread before retracting, occurring over the time scale of a few seconds. This phenomenon contradicts current understanding, exhibiting a uniquely (1) decreasing advancing contact angle and (2) increasing receding contact angle. To explain the behavior, we model such time- and space- dependent reactive wetting using first order kinetics. In doing so, we explore how reactive and recovery mechanisms govern the characteristic time scales of spreading and retracting sessile drops

Prediction of some peroxidase functions in Arabidopsis thaliana L. By bioinformatic search

Peroxidases of class III are common in various organisms. They are involved in lignin biosynthesis and plant protection against stressors. Peroxidases are presented in many isoforms, whose role is not always clear. The aim of this study is to analyze the amino acid sequences of reference peroxidases with known functions and peroxidases from Arabidopsis thaliana L. whose functions are unknown and to consider their putative roles in lignin biosynthesis. The structural and functional organization of peroxidases was analyzed by bioinformatical methods applied to open Internet sources. Seven reference peroxidases were chosen from four plant species: Zinnia sp., Armoracia rusticana P.G. Gaertn., Lycopersicon esculentum L. N Populus alba L. Twenty-four amino acid sequences of homologous peroxidases from A. thaliana were selected for the analyses with the BLAST service. Their molecular weights and isoelectric points were calculated. Multiple alignments of amino acid sequences and phylogenetic analysis were done. Sites of binding to monolignol substrates were identified in seven peroxidases from A. thaliana, and the enzymes were assigned to the groups of S- or G-peroxidases. Amino acid replacements in the primary structures of peroxidases were analyzed. Peroxidases from A. thaliana were clustered with reference peroxidases. They formed six clusters on the phylogenetic tree, three of which contained only A. thaliana peroxidases. Peroxidases within each cluster had similar molecular weights and isoelectric points, common localization of expression, and similar functions. Thus, the use of bioinformatics, databases, and published data bring us to assumptions as to the functions of several A. thaliana class III peroxidases. AtPrx39 peroxidase was shown to be affine to sinapyl alcohol; AtPrx54, to p-coumaryl and coniferyl alcohols. They are likely to participate in lignin biosynthesis. © Tugbaeva A.S., Ermoshin A.A., Kiseleva I.S., 2019

Rahmenbedingungen der digitalen Auskunft in den russischen Bibliotheken der Gegenwart

Themen, die mit russischen Bibliotheken verbunden sind, sind im europäischen Bibliothekswesen nicht breit dargestellt. Diesem Defizit wird in diesem Artikel mit dem Schwerpunkt auf Aspekten der digitalen Auskunft und den entspr. Rahmenbedingungen begegnet. Die vorgestellten Rechercheergebnisse basieren auf zwei Interviews: Einem Interview mit Irina Salikhovna, der Leiterin der Abteilung für elektronische Projekte der Russischen Nationalbibliothek und einem Interview mit Irina N. Lapina, welche die stellvertretende Direktorin der Puschkin-Zentralbibliothek von Nowokuibyschewsk ist.The topics connected to Russian libraries are not widely represented in European librarianship. This deficit is met in this article with a focus on aspects of Digital Information Services and its framework conditions. The presented research results are based on two interviews: an interview with Irina Salikhovna, the head of the Department of Electronic Projects of the Russian National Library, and an interview with Irina N. Lapina, the deputy director of the Pushkin Central Library of Novokuibyshevsk.Peer Reviewe

Improving the scientific and methodological foundations for strategic justification of infrastructure projects in the interests of Russia’s national security

The article is devoted to the problems of strategic justification of infrastructure projects, the financing of which is carried out with the involvement of the National Welfare Fund. The purpose of the study is to improve the scientific and methodological foundations of the strategic justification of an infrastructure project to increase the level of consistency of infrastructure projects with the system of strategic planning documents of the Russian Federation. General and general scientific cognition methods, methods of empirical and theoretical scientific cognition, and special methods determined by the essence of the object and subject of research were used in the work. The developed scientific and methodological foundations and proposals for the regulatory and legal regulation of the strategic justification of infrastructure projects in the interests of national safety of the Russian Federation are presented. The proposals presented in the article are intended to contribute to ensuring national safety and improving the competitiveness of the Russian Federation in the long term

Genetic Diversity in Local Taraxacum officinale L. Populations from Habitats Varied in Toxic Load

The level of lipid peroxidation (a stress indicator) and the quantitative traits of leaf tissue (the number and size of mesophyll cells and chloroplasts) were determined in Taraxacum officinale L. plants from five habitats near the city of Nizhniy Tagil that differ in terms of the heavy metal content in the soil. It is shown that in pollutedhabitats, the content of heavy metals (Cu2+ and Zn2+) in leaves is significantly higher compared to plants from background areas, with leaf thickness, mesophyll cell volume and chloroplast number per cell increasing. Both Inter Simple Sequence Repeat (ISSR) analysis and cluster analysis of dandelion genetic diversity based oneight primers have revealed that four groups of plants are closely related genetically. Of the observed differences between five local populations, 78% are caused by intrapopulation variability and 22% by interpopulation variability. It is supposed that Taraxacum officinale’s tolerance to heavy metal contamination in the studied localities is not genetically fixed adaptation, but acclimation within genetically selected rangesof tolerance.
