Book Reviews
Authors: Saltzman Matthew J.
Published: February 2015

The INFORMS Journal on Computing Book Review section covers books on subjects at the interface between operations research and computer science. We welcome books on theory, applications, computer systems, and generally any subject covered by an IJOC Area, or any combination of these. This includes both printed and electronic books. In addition, we consider comparative reviews, i.e. several books on one relevant topic. Team reviews are also possible, particularly for a large, broad-scope book such as an encyclopedia. Please send your suggestions for books to be reviewed to the IJOC book reviews editor.

This issue contains two reviews of books in the area of computational algebra and geometry, which is of increasing importance in discrete optimization. Modern Computer Algebra, Third Edition, by Joachim von zur Gathen and Jürgen Gerhard is a general introduction to the field, suitable for use as a text or research-level introduction. It covers algorithms for problems involving integers and polynomials. Reviewer Michael Burr calls the book, “practically useful while theoretically complete, providing intuition for the newcomer while also pointing the expert to more history and cutting edge results.” While Gathen and Gerhard’s book serves as an introduction to the field, Algebraic and Geometric Ideas in the Theory of Discrete Optimization, by Jesus A. De Loera, Raymond Hemmecke, and Matthias Köppe (reviewed by Jon Lee), connects those ideas to optimization. Lee reports that the book is oriented toward researchers who know discrete optimization as operations researchers and mathematical programmers who want to learn about advances made possible by applying methods from other areas of discrete mathematics.

Authors: Tuan Jayson , Farrell Michael
Published: February 2015

Tibial tuberosity advancement (TTA) is one of a number of techniques intended to provide dynamic stability to the cranial cruciate ligament (CCL)–deficient stifle joint. Over the past 10–15 years, there have been significant improvements in the understanding of the biomechanics of TTA, as well as the clinical outcome after treatment of dogs affected by naturally occurring CCL deficiency. Advances have been made in several aspects of TTA technique, including pre-surgical templating, surgical technique and implant design. This article includes a discussion of these recent advances and provides an overview of the experimental and clinical research on TTA surgery in dogs.
Reviving social work through moral outrage
Authors: Williams Charlotte , Briskman Linda
Published: February 2015

Inspired by Hessel’s (2011) call in Time for outrage and drawing on the concept of ‘moral outrage’, we argue in this article that addressing contraventions of human rights and social justice issues demands an emotional connection with the nature of injustice. We propose that contemporary social work in Western liberal democracies has lost touch with the moral imperative, sentiment and affective encounter as a positive impetus for collective action. We consider competing interpretations of why this might be the case and look beyond the incursions of neoliberal market methodologies towards a consideration of the complex relationships between power, subjectivities and collective emotion. Western epistemologies have viewed emotion as the antithesis of rationality and discouraged this type of thinking as somehow risky, tricky and dangerous. We seek to reconfigure this political and ethical (mis)appropriation of emotions and argue for its centrality within the social justice mandate of social work.
Analysis of Thin-Film Polymers Using Attenuated Total Internal Reflection–Raman Microspectroscopy
Authors: Tran Willie , Tisinger Louis G. , Lavalle Luis E. , Sommer Andre J.
Published: February 2015

Two methods commonly employed for molecular surface analysis and thin-film analysis of microscopic areas are attenuated total reflection infrared (ATR-IR) microspectroscopy and confocal Raman microspectroscopy. In the former method, the depth of the evanescent probe beam can be controlled by the wavelength of light, the angle of incidence, or the refractive index of the internal reflection element. Because the penetration depth is proportional to the wavelength of light, one could interrogate a smaller film thickness by moving from the mid-infrared region to the visible region employing Raman spectroscopy. The investigation of ATR Raman microspectroscopy, a largely unexplored technique available to Raman microspectroscopy, was carried out. A Renishaw inVia Raman microscope was externally modified and used in conjunction with a solid immersion lens (SIL) to perform ATR Raman experiments. Thin-film polymer samples were analyzed to explore the theoretical sampling depth for experiments conducted without the SIL, with the SIL, and with the SIL using evanescent excitation. The feasibility of micro-ATR Raman was examined by collecting ATR spectra from films whose thickness measured from 200 to 60 nm. Films of these thicknesses were present on a much thicker substrate, and features from the underlying substrate did not become visible until the thin film reached a thickness of 68 nm.
An Investigation of Micro-Hollow Cathode Glow Discharge Generated Optical Emission Spectroscopy for Hydrocarbon Detection and Differentiation
Authors: Vander Wal Randy L. , Gaddam Chethan K. , Kulis Michael J.
Published: February 2015

The analytical utility of a micro-hollow cathode glow discharge plasma for detection of varied hydrocarbons was tested using acetone, ethanol, heptane, nitrobenzene, and toluene. Differences in fragmentation pathways, reflecting parent compound molecular structure, led to differences in optical emission patterns that can then potentially serve as signatures for the species of interest. Spectral simulations were performed emphasizing the CH (A2Δ–X2Π), CH (C2∑–X2Π), and OH (A2∑+–X2Π) electronic systems. The analytical utility of selected emission lines is demonstrated by a linear relationship between optical emission spectroscopy and parent compound concentration over a wide range, with detection limits extending down to parts per billion (ppb) levels.
Surface-Enhanced Raman Scattering-Based Detection of Cancerous Renal Cells
Authors: Mert Sevda , Çulha Mustafa
Published: February 2015

Surface-enhanced Raman scattering (SERS) is used for the differentiation of human kidney adenocarcinoma, human kidney carcinoma, and non-cancerous human kidney embryonic cells. Silver nanoparticles (AgNPs) are used as substrate in the experiments. A volume of colloidal suspension containing AgNPs is added onto the cultured cells on a CaF2 slide, and the slide is dried at the overturned position. A number of SERS spectra acquired from the three different cell lines are statistically analyzed to differentiate the cells. Principal component analysis (PCA) combined with linear discriminate analysis (LDA) was performed to differentiate the three kidney cell types. The LDA, based on PCA, provided for classification among the three cell lines with 88% sensitivity and 84% specificity. This study demonstrates that SERS can be used to identify renal cancers by combining this new sampling method and LDA algorithms.
Benign Odontogenic Tumors versus Histochemically Related Tissues: Preliminary Results from Mid-Infrared and Solid-State Nuclear Magnetic Resonance Spectroscopy
Authors: Kolmas Joanna , Przαdka Rafał
Published: February 2015

Three types of human odontogenic tumors histologically classified as compound composite odontoma, ossifying fibroma, and Pindborg tumor were characterized using mid-infrared spectroscopy (mid-IR) and solid-state nuclear magnetic resonance (ssNMR). For comparison, human jawbone and dental mineralized tissues such as dentin, enamel, and dental cement were also characterized. The studies focused on the structural properties and chemical composition of pathological tissues versus histochemically related tissues. All analyzed tumors were composed of organic and mineral parts and water. Apatite was found to be the main constituent of the mineral part. Various components (water, structural hydroxyl groups, carbonate ions (CO32–), and hydrogen phosphate ions (HPO42–)) and physicochemical parameters (index of apatite maturity and crystallinity) were examined. The highest organic/mineral ratio was observed in fibrocementoma, a finding that can be explained by the fibrous character of the tumor. The lowest relative HPO42– content was found in odontoma. This tumor is characterized by the highest mineral crystallinity index and content of structural hydroxyl groups. The Pindborg tumor mineral portion was found to be poorly crystalline and rich in HPO42–. The relative CO32– content was similar in all samples studied. The results of spectroscopic studies of odontogenic tumors were consistent with the standard histochemical analysis. It was shown that the various techniques of ssNMR and elaborate analysis of the mid-IR spectra, applied together, provide valuable information about calcified benign odontogenic tumors.
Analysis of Impurity Effects on the Coloration of Corundum by Laser-Induced Breakdown Spectroscopy (LIBS)
Authors: Ho Sut Kam
Published: February 2015

Corundum was analyzed using laser-induced breakdown spectroscopy (LIBS) for impurity effects in their multiple colorings. Qualitative measurements were attained for impurities of chromium, magnesium, iron, and titanium in red, yellow, and blue samples. Moreover, treatment with a beryllium diffusion, which can modify corundum to obtain an attractive color, was tested in the yellow sample. In this work, most of the measurements were acquired using a laser pulse energy of 5 mJ and impurity emissions were appreciable. The signal-to-noise ratios were 11, 6.5,10, and 4 for the Cr 425.44 nm, Fe 404.58 nm, Be 313.04 nm, and Mg 285.21 nm lines, respectively, for five laser shots. The amount of damage to the corundum samples was also monitored by measuring the craters after laser analysis. It was found that the crater size was about 30 μm after 10 laser shots. As such, the damage to corundum sample is almost imperceptible after the LIBS analysis.
Fast Determination of Thiacloprid by Photoinduced Chemiluminescence
Authors: Catalá-Icardo Mónica , López-Paz José Luis , Pérez-Plancha Laura María
Published: February 2015

A new and sensitive application of chemiluminescence detection has been developed for the determination of the pesticide thiacloprid in water. It was based on the on-line photoreaction of thiacloprid in a basic medium, with quinine acting as the sensitizer of the chemiluminescent response; cerium (IV) in sulfuric acid medium was used as the oxidant. High degrees of automation and reproducibility were achieved using a flow-injection analysis (FIA) manifold. The validation of the method was performed in terms of selectivity, linearity, limit of detection (LOD), precision, and accuracy. Liquid chromatography with ultraviolet (UV) detection was used as reference for mineral, tap, ground, and spring water samples. The proposed method is fast (with a throughput of 130 h−1), sensitive (LOD of 0.8 ng mL−1 without preconcentration steps and of 0.08 ng mL−1 with solid-phase extraction [SPE]), low cost, and possible to couple with separation methods for the simultaneous determination of other pesticides. The enhanced chemiluminescence intensity was linear with the thiacloprid concentration above the 2–80 and 80–800 ng mL−1 ranges. A possible reaction mechanism is also discussed.
Subsurface Raman Analysis of Thin Painted Layers
Authors: Conti Claudia , Colombo Chiara , Realini Marco , Zerbi Giuseppe , Matousek Pavel
Published: February 2015

Here we present, for the first time, an extension of spatially offset Raman spectroscopy to thin (tens of micrometers thick), highly turbid stratified media such as those encountered in paintings. The method permits the non-destructive interrogation of painted layers in situations where conventional Raman microscopy is not applicable due to high turbidity of the top layer(s). The concept is demonstrated by recovering the pure Raman spectra of paint sub-layers that are completely obscured by paint over-layers. Potential application areas include the analysis of paintings in art preservation and restoration avoiding the cross-sectional analysis used currently with this type of samples. The technique also holds promise for the development as a non-destructive subsurface tool for in situ analysis using portable instruments.
A Line-Scan Hyperspectral System for High-Throughput Raman Chemical Imaging
Authors: Qin Jianwei , Chao Kuanglin , Kim Moon S.
Published: February 2015

A line-scan hyperspectral system was developed to enable Raman chemical imaging for large sample areas. A custom-designed 785 nm line laser based on a scanning mirror serves as an excitation source. A 45° dichroic beam splitter reflects the laser light to form a 24 cm × 1 mm excitation line normally incident on the sample surface. Raman signals along the laser line are collected by a detection module consisting of a dispersive imaging spectrograph and a CCD camera. A hypercube is accumulated line by line as a motorized table moves the samples transversely through the laser line. The system covers a Raman shift range of −648.7 to 2889.0 cm−1 and a 23 cm wide area. An example application for authenticating milk powder is presented to demonstrate the system performance. In 4 min the system acquired a 512 × 110 × 1024 hypercube (56 320 spectra) from four, 47 mm diameter Petri dishes containing four powder samples. Chemical images were created for detecting two adulterants (melamine and dicyandiamide) that had been mixed into the milk powder.

Authors: Rico Cyren M. , Peralta-Videa Jose R. , Gardea-Torresdey Jorge L.
Published: February 2015

Cerium oxide nanoparticles (nCeO2) have extensive industrial applications, and concerns regarding their threat to the environment have been raised. This study includes structural analysis of intact root xylem of rice ( Oryza sativa L.), wheat ( Triticum aestivum L.), and barley ( Hordeum vulgare L.) seedlings exposed to nCeO2 suspensions (0, 62.5, 125, 250, and 500 mg L−1). Fourier transform infrared microspectroscopy was applied to determine compositional alterations in the root xylem, and principal component analysis (PCA) was carried out to examine spectral differences between nCeO2 treatments. Results demonstrated that nCeO2 at > 125 mg L−1 changed the region of spectra around 1696-1760 cm−1 in rice root, 125 and 250 mg L−1 modified 1744-1792 cm−1 in wheat, and 62.5 and 125 mg L−1 altered 1727-1760 cm−1 in barley. PCA afforded the clustering of nCe02 treatments at 0 and 62.5 mg L−1 in rice and wheat and 0 and 500 mg L−1 in barley. Furthermore, major peaks at 1744 or 1760 cm−1 appeared in primary PC and 1728 cm−1 in secondary PC score loadings. These findings illustrated that nCeO2 induced compositional modifications in the root xylem of cereals.
Nondestructive Identification of Dye Mixtures in Polyester and Cotton Fibers Using Raman Spectroscopy and Ultraviolet–Visible (UV-Vis) Microspectrophotometry
Authors: Was-Gubala Jolanta , Starczak Roza
Published: February 2015

Presented in this paper is an assessment of the applicability of Raman spectroscopy and microspectrophotometry (MSP) in visible and ultraviolet light (UV–Vis) in the examination of textile fibers dyed with mixtures of synthetic dyes. Fragments of single polyester fibers, stained with ternary mixtures of disperse dyes in small mass concentrations, and fragments of single cotton fibers, dyed with binary or ternary mixtures of reactive dyes, were subjected to the study. Three types of excitation sources, 514, 633, and 785 nm, were used during Raman examinations, while the MSP study was conducted in the 200 to 800 nm range. The results indicate that the capabilities for discernment of dye mixtures are similar in the spectroscopic methods that were employed. Both methods have a limited capacity to distinguish slightly dyed polyester fiber; additionally, it was found that Raman spectroscopy enables identification of primarily the major components in dye mixtures. The best results, in terms of the quality of Raman spectra, were obtained using an excitation source from the near infrared. MSP studies led to the conclusion that polyester testing should be carried out in the range above 310 nm, while for cotton fibers there is no limitation or restriction of the applied range. Also, MSP UV–Vis showed limited possibilities for discriminatory analysis of cotton fibers dyed with a mixture of reactive dyes, where the ratio of the concentration of the main dye used in the dyeing process to minor dye was higher than four. The results presented have practical applications in forensic studies, inter alia.
Development and Metrological Characterization of a Tunable Diode Laser Absorption Spectroscopy (TDLAS) Spectrometer for Simultaneous Absolute Measurement of Carbon Dioxide and Water Vapor
Authors: Pogány Andrea , Wagner Steven , Werhahn Olav , Ebert Volker
Published: February 2015

Simultaneous detection of two analytes, carbon dioxide (CO2)and water vapor (H2O), has been realized using tunable diode laser absorption spectroscopy (TDLAS) with a single distributed feedback diode laser at 2.7 μm. The dynamic range of the spectrometer is extended from the low parts per million to the percentage range using two gas cells, a single-pass cell with 0.77 m, and a Herriott-type multipass cell with 76 m path length. Absolute measurements were carried out, i.e., amount fractions of the analytes were calculated based on previously determined spectral line parameters, without the need for an instrument calibration using gas standards. A thorough metrological characterization of the spectrometer is presented. We discuss traceability of all parameters used for amount fraction determination and provide a comprehensive uncertainty assessment. Relative expanded uncertainties ( k = 2, 95% confidence level) of the measured amount fractions are shown to be in the 2-3% range for both analytes. Minimum detectable amount fractions are 0.16 μmol/mol for CO2 and 1.1 μmol/mol for H20 for 76 m path length and 5 s averaging time. This corresponds to normalized detection limits of 27 μmol/mol m Hz_1/2 for CO2 and 221 μmol/mol m Hz−1/2 for H2O. Precision of the spectrometer, determined using Allan variance analysis, is 3.3 nmol/mol for CO2 and 21 nmol/mol for H2O. The spectrometer has been validated using reference gas mixtures with known CO2 and H2O amount fractions. An application example of the absolute TDLAS spectrometer as a reference instrument to validate other sensors is also presented.
Determination of Free Electron Density in Sequentially Doped InxGa1-xAs by Raman Spectroscopy
Authors: Kort Kenneth R. , Hung P.Y. , Loh Wei-Yip , Bersuker Gennadi , Banerjee Sarbajit
Published: February 2015

The advent and exponential growth of mobile computing has spurred greater emphasis on the adoption of III–V compound semiconductors in device architectures. The introduction of high charge carrier densities within InxGa1-xAs and the development of metrologies to quantitate the extent of doping have thus emerged as an urgent imperative. As an amphoteric dopant, Si begins to occupy anionic sites at high concentrations, thereby limiting the maximum carrier density that can be obtained upon Si doping of III–V semiconductors. Here, we present Raman results on sequentially doped In0.53Ga0.47As wherein sulfur monolayer doping is used to introduce additional carrier density to Si-doped samples. The sequential doping of Si and S allows for high carrier concentrations of up to 1.3 × 1019 cm−3 to be achieved without damaging the III–V lattice. The coupling of the plasmon in the doped samples to the longitudinal optic phonons allows Raman spectroscopy to serve as an excellent probe of the extent of dopant activation, charge carrier density, and the surface depletion region. In particular, the energy position of a high-frequency coupled mode (HFCM) that is detected above 400 cm−1 is used to extract the free electron density in these samples. The extracted free electron densities are well correlated with measured sheet resistance values and the carrier densities deduced from Hall measurements.
Dapper dudes: Young men’s fashion consumption and expressions of masculinity
Authors: Barry Ben , Martin Dylan
Published: February 2015

Men’s fashion is offering a growing selection of diverse and gender-blurring clothing for mainstream male consumers. This research explores the influence of these contemporary clothing trends on the dressing practices and gendered identities of style-conscious young men – a group of consumers whose voices are scarce in fashion research. Findings from the Canadian sample reveal that young men develop an idiosyncratic and creative sense of style to express their identities. While shifts in menswear and culture have inspired them to participate in fashion, social norms continue to prevent men from fully experimenting with dress. This study reveals the factors that influence young men’s fashion consumption and highlights changes in their consumer practices, including their use of social media. Fashion professionals will glean an understanding of Generation Y men’s fashion consumption habits and attitudes. They are advised to develop brands that focus on creativity and community to reach this audience.

On the hidden significance of differing micro-sites on tree-ring based climate reconstructions
Authors: Düthorn Elisabeth , Schneider Lea , Konter Oliver , Schön Philipp , Timonen Mauri , Esper Jan
Published: February 2015

Tree-ring chronologies are commonly extended back in time by combining samples from living trees with relict material preserved in man-made structures or natural archives (e.g. lakes). Although spatially close, these natural archives and living-tree-sites often comprise different micro-climates. Inhomogeneous growth conditions among these habitats, which may yield offsets in growth-rates, require caution in data processing. Here we assess species-specific growth dynamics in two micro-habitats and their potential effects on long chronologies by combining tree-ring data from different living-tree-sites with an âartificialâ subfossil dataset. Well replicated (nâ>â80) Norway spruce ( (L.) Karst.) and Scots pine ( L.) chronologies from northern Fennoscandia, sampled directly at the lakeshore (wet) and several meters beyond the lakeshore (dry) reveal high coherence of the variance between micro-sites (â=â0.59, â=â0.68). Significant differences of the Regional Curves (RC) indicate faster growth of both species at the drier site though. Growth differences are more pronounced between the spruce micro-sites. The combination of recent dry and wet spruce data with artificial relict data results in two long chronologies covering the last 800 years with substantially different trends, although they consist of the same relict material and the micro-site chronologies correlate significantly over the past two centuries. The combination of spruce samples from dry inland micro-sites with subfossil samples originating from the wet lake shore can result in an underestimation of past temperatures prior to the 19th century. Such effects, hidden in the composition of long chronologies (living treesâ+âsubfossil samples) can bias long-term trends in climate reconstructions.Picea abiesPinus sylvestrisrsprucerpine

Perception of colour scales used in thematic cartography by young people aged 15-17
Authors: Musilová Barbora
Published: February 2015

There are many different types of datasets represented by maps in thematic cartography. It is possible to represent features and phenomenon referencing to area as well as to point. Furthermore, it is possible to represent qualitative data as well as quantitative data. There are many different ways to represent them. One of the most important and most used cartographic symbols of lettering is colour, resp. colour scales, which are chosen according to shown data. This article is focused on the perception of colour scales in relation to character of data. For experiment, a new questionnaire was created on the basis of colour scales classification. This questionnaire was posed to the students of years 1 and 2 of high school in order to find out how they perceive the colour scales. The study analyzes three main questions; whether students differentiate qualitative and quantitative datasets and corresponding colour scales, whether they prefer representing of features by context colours or by the colour they like more and whether they are familiar with principles of diverging colour scales. When processing it, the correlation between certain agents and the answers was established.

Reference Data as a Basis for National Spatial Data Infrastructure
Authors: Mildorf Tomáš , Čada Václav
Published: February 2015

Spatial data are increasingly being used for a range of applications beyond their, traditional uses. Collection of such data and their update constitute a substantial part of the total costs for their maintenance. In order to ensure sustainable development in the area of geographic information systems, efficient data custody and coordination mechanisms for data sharing must be put in place. This paper shows the importance of reference data as a basis for national spatial data infrastructure that serves as a platform for decision making processes in society. There are several European initiatives supporting the wider use of spatial data. An example is the INSPIRE Directive. Its principles and the main world trends in data integration pave the way to successful SDI driven by stakeholders and coordinated by national mapping agencies.

Visual Kei ist mit der Jahrtausendwende von Japan nach Europa gekommen. Die Subkultur zeichnet sich durch ästhetische Inszenierungspraxen aus, in denen Konzeptionen von Körper und Geschlecht fluide erscheinen. Die vertraute Geschlechtsbinarität wird überschritten: Eine Zuordnung zu den Polen »männlich« oder »weiblich« wird erschwert und auch heterosexuelles Begehren wird in Frage gestellt. Wie konstituieren sich Subjekte in und durch Praxis? Und wie werden sie darin anerkannt, möglich und lebbar? Nadine Heymanns ethnographische Studie geht diesen Fragen vor dem Hintergrund von Bourdieus Theorie der Praxis und Butlers Konzept der Performativität nach.

The variational iteration method for solving the Volterra integro-differential forms of the Lane-Emden and the Emden-Fowler problems with initial and boundary value conditions
Authors: Wazwaz Abdul-Majid , Khuri Suheil A.
Published: February 2015

In this paper, the variational iteration method (VIM) is used to examine the Volterra integro-differential forms of the singular Lane–Emden and the Emden–Fowler initial value problems and boundary value problems arising in physics, astrophysics and stellar structures. The Volterra integro-differential forms of the Lane–Emden and the Emden–Fowler equations overcome the singularity behavior at the origin x = 0. The Lagrange multiplier, needed for the VIM, is λ = −1 for the various cases of the specified equations having distinct shape factors. We illustrate our work by analyzing few initial value problems and boundary value problems to emphasize the convergence of the acquired results.

Novel rel-(5R,6S,7S)-2-oxo-5,7-diaryl-3,5,6,7-tetrahydro-2H-thiopyrano[2,3-d]thiazol-6-yl-oxo-acetic acids were synthesized in 52–70% yields via regioselective and diastereoselective hetero-Diels-Alder reaction of 5-arylidene-4-thioxo-2-thiazolidinones with a series of arylidene pyruvic acids. The synthesized compounds were evaluated for anticancer activity in NCI60 cancer cell lines and for antiexudative activity on the carrageenan edema model in rats. Biological screening data led to identification of 3e as having moderate antitumor activity on the colon cancer HT-29 cell line and of 3b as having promising antiexudative effect.

Authors: Chetverushkin Boris , D’Ascenzo Nicola , Ishanov Sergey , Saveliev Valeri
Published: February 2015

The article presents the developments of the kinetic consistent approach of solution of the magneto gas dynamics problems on the high performance computing systems with massive parallelism. The main idea is to derive the magneto gas dynamic equations from the Boltzmann equation using a complex distribution function, including the electromagnetic terms. The derived equations were used for the formulation of the explicit numerical method of solution for the high performance parallel computing systems. The numerical experiments were performed for the verification of the chosen method.
On evolution of solution times for the chemical master equation of the enzymatic futile cycle
Authors: Dolgov Sergey V. , Tyrtyshnikov Eugene E.
Published: February 2015

We investigate three tensor product numerical data compression techniques in solution of the chemical master equation for the enzymatic futile cycle and compare them with the previously reported results, obtained by the stochastic simulation algorithm. On this particular example from systems biology, we show the history how the newly proposed tensor product methods reduced the computational complexity of the futile cycle modelling from days on a HPC cluster to hours and even minutes on a workstation.

Published: February 2015

Bis[bis(dimethylamino)phosphino]acetylene (2a) and two molecules of dimethyl- and diethyl-acetylenedicarboxylate (1a /1b ) react in a criss-cross-cycloaddition to yield 1λ5 ,4λ5- diphosphapentalenes (3), which react further with 1 to yield a 1λ5 ,4λ5-diphosphaazulenes (5). A mechanism of both reactions is proposed. The reaction of 1λ5,4λ5-diphosphaazulene with 1a at high pressure yields 1,1,4,4-tetrakis(dimethylamino)-3,5,6,7,8 -pentakis(methoxycarbonyl)- 2-[1,2,2tris(methoxycarbonyl)ethenyl]-1λ5,4λ5 -diphosphaazulene (7). The reaction of bis(diphenylphosphino) acetylene (2c) with 1a yields 1,5a-dihydro-1-methoxy-(1-methoxycarbonylethinyl)- 3,3,7,7-tetraphenyl)-2-oxa-3λ5,7λ5 -diphosphacyclopenta[1,2,3-c,d]azulene- 4,5,5a,6,8,9-hexakis(methoxycarbonyl) (9) and 4-(diphenylphosphoryl)-5-[1,2-bis-(methoxycarbonyl)- ethylidene]-1λ5-phosphol-2,3-bis(methoxycarbonyl) (10)
Coordination Chemistry of Lipoic Acid and Related Compounds, Part 1 Syntheses and Crystal Structures of the UV- and Light-Sensitive Lipoato Complexes [M(lip)2(H2O)2] (M = Zn, Cd)

Published: February 2015

The rac-lipoato (lip-) complexes [Zn(lip)2(H2O)2] (1) and [Cd(lip)2(H2O)2] (2) were obtained in good yields from solutions of sodium lipoate and the respective metal nitrate in methanol/water. 1 and 2 form pale yellow, moderately light-sensitive crystals.

Both compounds were structurally characterized by single-crystal X-ray diffraction. 1: C2/c, a = 39.958(6), b = 5.360(1), c = 10.794(1) Å, β = 95.76(1)°, Z = 4, wR2 = 0.150 (all data). 2: C2/c, a = 38.200(2), b = 5.472(1), c = 11.179(1) Å, β = 92.72(1)°, Z = 4, wR2 = 0.090 (all data). The metal ions are hexacoordinated by the oxygen atoms of two chelating carboxylate ligands and two aqua ligands. The crystal structures are very similar but not isotypic. They are layer structures, in which the complexes within a layer are interconnected by a network of hydrogen bonds. Adjacent layers have contacts via the 1,2-dithiolanyl rings of their lipoato ligands.

Crystals of 1 and 2 decompose on exposure to visible light or ultraviolet radiation in the 280-390 nm range. Photopolymerization by formation of intermolecular S-S bonds is very probably involved. Furthermore, the infrared spectra reveal the transformation of COO- into COOH groups
