Abstract:
Structure connection tables, which are commonly used for the representation of chemical structures in electronic databases, are valuable for substances where specific valence bond structures are known or can be drawn. How-ever there are many classes of substances (for example alloys, catenanes, polymers, or salts) which cannot be fully represented by valence bond structures. There are also issues of definition (such as when a substance is a co-ordination compound, or hydrate, or salt), and of bonding types (resonance, donor complexes, π-complexes). Producers of chemical substance databases may

AbstractSome rose cultivars such as City of Belfast are more resistant to the western flower thrips, Frankliniella occidentalis (Pergande) than others. Data from life tables and behavioural studies indicate that the reason for resistance may be physiological-chemical as well as the physical structure and colour of the flower. Some rose odours repelled F. occidentalis.

Abstract:
Every cell in a living organism is constantly exposed to physical and chemical factors which damage the molecular structure of proteins, lipids, and nucleic acids. Cellular DNA lesions are the most dangerous because the genetic information, critical for the identity and function of each eukaryotic cell, is stored in the DNA. In this review, we describe spectroscopic markers of DNA damage, which can be detected by infrared, Raman, surface-enhanced Raman, and tip-enhanced Raman spectroscopies, using data acquired from DNA solutions and mammalian cells.

Roll compaction is a continuous process commonly used in the pharmaceutical industry for dry granulation of moisture and heat sensitive powder blends. It is intended to increase bulk density and improve flowability.

The structure of polytopes—polytopic prismahedrons, which are products of polytopes of lower dimensionality—is investigated. The products of polytopes do not belong to the well-studied class of simplicial polytopes, and therefore their investigations are of independent interest. Analytical dependencies characterizing the structure of the product of polytopes are obtained as a function of the structures of polytope factors. Images of a number of specific polytopic prismahedrons are obtained, tables of structures of polytopic prismahedrons are compiled, depending on the types of polytopes of the

The Bohr model of atomic structure consists of electrons (negatively charged) revolving around the nucleus (positively charged) at certain (quantized) fixed distances in a set of orbits.

‘Electronic structure’ examines the work that went into determining the properties of electrons in atoms. Quantum theory was devised by Max Planck in 1900, and was applied to hydrogen atoms by Niels Bohr in 1913. Bohr hypothesized that electrons existed in set shells around a nucleus and then extrapolated this theory, using chemical rather than physical observations, to other elements. G. N. Lewis hypothesized a cube model of electron arrangement around the nucleus. Despite this not being correct, Lewis concluded that chemical bonding was due to the pairing of electrons, an idea still central

The variation in orbital energies across the periodic table can be understood in terms of the increase in nuclear charge, the extent to which different electrons screen one another from the nucleus, and the shell to which a particular orbital belongs.
