Abstract:
Boranes, despite their instability in nature, can be regarded as hydrocarbon relatives since a [BH] fragment corresponds to a carbon [C] skeletal element in terms of the number of valence electrons. The borane formula which can be expressed as BnHm usually appears in such a way that when (n) is even, then (m) is even and when (n) is odd, (m) is odd as well. Through the study of cluster series, it appears that the cluster number K which represents skeletal linkages is usually a whole number. This inherent characteristic confers unique order within borane clusters with nodal connectivity of 5 and the polyhedral nature of the borane clusters. The orderliness of the borane clusters is reflected by the ease of their categorization into clan series and their readily constructed geometrical isomeric structures. The cluster valence electrons can easily be calculated using one of the six recently discovered fundamental equations.

Abstract:
Whereas many of the capped series of carbonyl clusters of transition metals are known, those of corresponding borane series are unknown. These include the monocapped, bicapped, tricapped, tetracapped and so on. This paper attempts to correlate selected capped series of the carbonyl series with the hypothetical corresponding ones of boranes using 14n and 4n rules. Some selected examples of capped and decapped borane series have been generated and tabulated. The borane clusters are found to follow a precise numerical algorithm. A comparison of selected examples of carbonyl cluster of lower series such as closo, nido and arachno with the corresponding borane clusters has been made. The popularly cited Rudolph system of deducing shapes of clusters is also discussed in terms of decapping series. The use of fragments and their corresponding fragment series enormously simplifies the categorization of molecular formulas into series from which their shapes can be predicted with or without the use of the cluster number (k value). The fragment series vindicates the vital Hoffmann’s isolobal concept very well.

Abstract:
A review is presented on the methods of incorporation of phosphorus vertices into borane, carborane and heteroborane clusters. The structural diversity of boron cluster compounds allows for the synthesis of various types of phosphaboranes, phosphacarboranes and phosphaheteroboranes of structurally different cluster shapes, sizes, and positional isomerism. The phosphaborane compounds outlined in this work are direct analogues of corresponding carboranes. This analogy is the main reason for recent interest and developments in this area.

Abstract:
Thermodynamic hydricity (HDAMeCN) determined as Gibbs free energy (ΔG°[H]−) of the H− detachment reaction in acetonitrile (MeCN) was assessed for 144 small borane clusters (up to 5 boron atoms), polyhedral closo-boranes dianions [BnHn]2−, and their lithium salts Li2[BnHn] (n = 5–17) by DFT method [M06/6-311++G(d,p)] taking into account non-specific solvent effect (SMD model). Thermodynamic hydricity values of diborane B2H6 (HDAMeCN = 82.1 kcal/mol) and its dianion [B2H6]2− (HDAMeCN = 40.9 kcal/mol for Li2[B2H6]) can be selected as border points for the range of borane clusters’ reactivity. Borane clusters with HDAMeCN below 41 kcal/mol are strong hydride donors capable of reducing CO2 (HDAMeCN = 44 kcal/mol for HCO2−), whereas those with HDAMeCN over 82 kcal/mol, predominately neutral boranes, are weak hydride donors and less prone to hydride transfer than to proton transfer (e.g., B2H6, B4H10, B5H11, etc.). The HDAMeCN values of closo-boranes are found to directly depend on the coordination number of the boron atom from which hydride detachment and stabilization of quasi-borinium cation takes place. In general, the larger the coordination number (CN) of a boron atom, the lower the value of HDAMeCN.

Abstract:
The syntheses, structures, and magnetic properties of a series of di/trivalent hydridotris(3,5-dimethylpyrazol-1-yl)borate (Tp*) cyanomanganates were investigated. Treatment of manganese(III)acetylacetonate with KTp* followed by tetra(ethyl)- ammonium cyanide affords [NEt4][(Tp*)MnII(acac)(CN)] (1). Attempts to oxidize 1 with iodine affords {(Tp*)MnII(κ2O-acac-CN)}n (7); a minor complex {[NEt4][(Tp*)MnII(κ2O-acac-3-CN)]2(µ-CN) (8) was also isolated. The manganese(II) complex [NEt4][(Tp*)MnII(κ2O-acac-3-CN)(κ1N -3-NC-acac)] (2) was obtained via treatment of Mn(3-acacCN)3 with KTp* and [NEt4]CN. [NEt4]2[MnII(CN)4] (3) was prepared via treatment of Mn(OTf)2 with excess [NEt4]CN. [NEt4][(Tp*)MnIII(CN)3] (4), is prepared via treatment of 4 with Mn(3-acacCN)3, KTp* and excess [NEt4]CN. [PPN][(Tp*)MnIII(CN)3] (5) is obtained via treatment of [PPN]3[MnII(CN)6] with (Tp*)SnBu2Cl. Combination of 4 with [MnII(bipy)2(OH2)2][OTf]2 afforded a tetranuclear rectangular cluster {MnIII 2MnII 2} (9). At low temperature, {MnIII2NiII2} (10) was prepared via treatment of 4 and [Ni(II)(bipy)2(H2O)2][OTf]2. Treatment of 4 with [CoII(bipy)2(OH2)2][OTf]2 at low temperature failed to give the desired {MnIII2CoII2} complex. Magnetic measurements indicate that 1, 2, and 7 contain high-spin isotropic MnII with no long-range magnetic order observed for 7 (T > 2 K); 4 contains low-spin MnIII that likely adopt an isotropic 3A2 spin ground state. Surprisingly 9 and 10 do not exhibit slow relaxation of the magnetization (for T > 1.8 K) despite the presence of significant molecular anisotropy.

Abstract:
Une nouvelle synthèse stéréosélective d’acides phosphineux-borane est décrite par hydrolyse d’aminophosphines borane préparées par réaction d'organolithiens sur un complexe d'oxazaphospholidine-borane dérivé de l'éphédrine. Par réaction avec un acide fort, ces acides phosphineux-borane conduisent aux oxydes de phosphines secondaires P-chirogéniques correspondants avec de très bons rendements (90%) et rétention complète de la configuration sur l'atome de phosphore. Les oxydes de phosphines secondaires ont été utilisés en catalyses d'hydrogénation et de Heck asymétriques par des complexes de rhodium et de palladium. Dans une seconde partie, une nouvelle synthèse d’oxydes de phosphines P-chirogéniques substitués par des groupements ortho halogénophényles a été décrite. Le principe de cette synthèse repose sur l’addition d’un oxyde de phosphine secondaire sur un benzyne préparé in situ à partir de dihalogénobenzène. Ces oxydes de phosphines o-halogénés ont été utilisés en synthèse de nouveaux dérivés fonctionnalisés en position ortho par des réactions d’homocouplage par le cuivre ou d’hétérocouplage catalysée par des complexes de palladium. Dans une dernière partie, la préparation de clusters de cuivre chiraux a été réalisée en utilisant des monophosphines P-chirogéniques. La structure par rayons X, le dichroïsme circulaire, et les propriétés photophysiques des clusters chiraux sont présentés
A new stereoselective synthesis of phosphinous acid boranes is described by hydrolysis of aminophosphines boranes prepared by reaction of the oxazaphospholidine complex derived from ephedrine with organolithium reagents.By reaction with a strong acid, the phosphinous acid boranes lead to the corresponding P-chirogenic secondary phosphine oxides in very good yields (90%) and with complete retention of the configuration at the phosphorus atom. The secondary phosphine oxides have been used in asymmetric hydrogenation and intramolecular Heck cyclisation using rhodium and palladium complexes, respectively. In a second part, a new synthesis of P-chirogenic ortho-halogenophenyl phosphine oxides is described. The principle of this synthesis is based on the addition of secondary phosphine oxides to a benzyne, prepared in situ from dihalogenobenzene. The o-halogenophenylphosphine oxides were used to prepare many functionalized derivatives in ortho position by reactions such as homocoupling with copper or heterocoupling catalyzed by palladium complexes. In the last part, the synthesis of chiral copper clusters was performed using P-chirogenic monophosphines.

Abstract:
Rising global antibiotic resistance has caused concerns over sources and pathways for the spread of contributing factors. Majority of the antimicrobials used in the U.S. are involved in veterinary medicine, primarily with livestock rearing. Animal manure land application integrates livestock farming and agroecosystems. This manure contains antibiotic resistant elements (AREs) (resistant bacteria, resistance genes, and veterinary antibiotics) that contribute towards antimicrobial resistance. Altering manure application techniques can reduce surface runoff of other contaminants such as excess N and P, pesticides, and hormones, that can impact water quality. Conventional tillage practices in the U.S. has reduced or stopped, making subsurface injection of manure a promising option when compared to surface application. Our research compared manure application methods, manure application seasons, cropping system, and manure-rainfall time gaps to gauge the impact on AREs in the environment. Two field-scale rainfall simulation studies were conducted along with one laboratory study. Using the injection method lowered concentrations of manure associated AREs entering surface runoff. When manure was surface applied and rainfall occurred 7 d after application, 9-30 times less resistant fecal coliform bacteria (FCB) entered surface runoff when compared to 1 d time gap for that broadcast method. Within a day of manure application, antibiotic resistance gene (ARG) profiles in soil began to differ from each other based on manure application and soil ARG richness in all manure-amended soil increased compared to the background. Runoff from injection plots contained 52 ARGs with higher abundance compared to runoff from surface applied plots. ARGs in the former were more correlated to soil and more correlated to manure in the latter. The highest antibiotic concentrations were in the injection slit soil of those plots. Antibiotic concentrations in samples corresponded positively to concentrations of resistant FCB and ARGs, and there was a positive correlation between resistant FCB and their associated ARGs (Spearman's ρ = 0.43-0.63). A CRIISPR-Cas12a assay for quantification of ARGs in environmental samples was just as precise as conventional methods. There is also potential for in-situ detection. These combined results can hopefully help farmers improve manure management practices that mitigate spread of AREs to surrounding water, crops, and soil.

Rising global antibiotic resistance cause concerns over sources and pathways for the spread of contributing factors. Most of the antimicrobials used in the U.S. are involved in veterinary medicine, especially with livestock rearing. Overuse of antibiotics that are medically important to human medicine compromises the effectiveness of our medicines. Animal manure contains antibiotic resistant elements (AREs) such as resistant bacteria, resistance genes, and antibiotics) that contribute towards resistance issues. Once these AREs enter the environment, they can be taken up by crops, runoff into surface water or leached into ground water, or even reside within the animal products we consume. Altering manure application techniques is beneficial for nutrient conservation but also potentially for reducing ARE spread. With our research, we compared manure application methods, manure application seasons, cropping systems, and manure-rainfall time gaps to find ways to balance the need for manure application and the spread of resistance. We used two field-scale rainfall simulation studies along with one laboratory study. Overall, using the injection method resulted in significantly lower concentrations of manure associated AREs entering surface runoff. When manure was surface applied and rainfall occurred 7 d after application, less resistant fecal coliform bacteria (FCB) entered surface runoff when compared to the 1 d time gap for broadcast methods. Within a day of manure application, antibiotic resistance gene (ARG) profiles in soil began to differ from each other and soil ARG totals in all manure applied soil increased compared to the background. Runoff from injection plots contained more soil ARGs and runoff from surface applied plots containing more manure associated ARGs. The subsurface injection method also caused highest antibiotic concentrations in the injection slit soil of those plots. High antibiotic concentrations in samples generally meant high concentrations of resistant FCB and ARGs, and resistant FCB were also found with their associated ARGs as well. A CRISPR-Cas12a assay for quantification of ARGs in environmental samples was just as precise as conventional methods. There is also potential for onsite detection. These combined results can hopefully help farmers improve manure management practices that mitigate spread of AREs to surrounding water, crops, and soil.

Abstract:
L’ascomicete Guignardia bidwellii, agente causale del marciume nero della vite, è un patogeno economicamente importante in alcuni areali viticoli. La conoscenza, disponibile sul marciume nero dell’uva, è stata recuperata dalla letteratura, analizzata e sintetizzata per sviluppare un modello meccanicistico del ciclo di vita del patogeno, guidata dalle variabili meteorologiche e dalla fenologia della vite, e basata sull'analisi dei sistemi. Il modello è stato poi valutato per la sua capacità di rappresentare il sistema reale e la sua utilità per la comprensione di epidemie di marciume nero su foglie e grappoli in un vigneto del Nord Italia, nel 2013 al 2015. Successivamente, le mancanze di conoscenza sono state analizzate, studiate e quindi colmate attraverso specifici esperimenti. In un primo passo, le dinamiche dell’inoculo primario e dei modelli di dispersione (di entrambi ascospore e conidi) da mummie svernate sono state studiate in un vigneto sperimentale per tre anni. In un secondo passo, l'effetto della temperatura e dell'umidità sulla formazione di picnidi di G. bidwellii e la successiva estrusione di cirri, nelle lesioni su foglia, la produzione e la germinazione dei conidi (inoculo secondario), e la lunghezza del periodo di latenza sono stati studiati sia in condizioni di campo che in ambiente controllato. In un terzo passo, sono stati condotti studi in ambiente controllato per studiare la produzione di conidi di G. bidwellii sulle lesioni di foglie, influenzata da lavaggi ripetuti e alternando periodi di secco ed umido. Il modello epidemiologico sviluppato in questa tesi può essere utilizzata da viticoltori come strumento predittivo per la pianificazione di trattamenti fungicidi nei vigneti.
The ascomycete Guignardia bidwellii, causal agent of black-rot on grapevines, is an economically important pathogen in some viticultural areas. The available knowledge on black-rot of grape was retrieved from literature, analyzed, and synthesized to develop a mechanistic model of the life cycle of the pathogen, driven by weather and vine phenology, and based on the systems analysis. The model was then evaluated for its ability to represent the real system and its usefulness for understanding black-rot epidemics on leaves and bunches in a vineyard of north Italy, in 2013 to 2015. Thereafter, weaknesses in our knowledge were analysed and studied through specific experiments. In a first step, dynamics of primary inoculum and dispersal patterns (both ascospores and conidia) from overwintered grape mummies were investigated in an experimental vineyard during three years. In a second step, the effect of temperature and humidity on the formation of G. bidwellii pycnidia and the extrusion of cirri in grape leaf lesions, production and germination of conidia (secondary inoculum), and the length of the latency period were studied under both environmental and controlled conditions. In a third step, environmental-controlled studies were conducted to investigate the production course of G. bidwellii conidia on grape leaf lesions as influenced by repeated washing events and alternate dry and wet periods. The model developed in this thesis can be used by vinegrowers as a predictive tool for scheduling fungicide sprays in the vineyards.

Abstract:
This thesis entitled “Electronic Structure and Bonding in Metallaboranes and Main Group Compounds” consists of five chapters. Chapter 1 gives an exposition of concepts and techniques used in understanding the electronic structure and bonding in some chemically interesting molecules. Heuristics concepts like isolobal analogy and electron counting rules are used in analyzing and predicting some novel chemical systems. A brief description of computational techniques such as density functional theory (DFT) based methods are used to quantitatively examine the structures and energies of these systems. In chapter 2 we present a critical analysis of bonding in neutral and dianionic stannadiphospholes and compare the potential energy surfaces with the isoelectronic Cp+ and Cp- species. The analysis indicates that Sn can be a better isolobal analogue to P+ than to BH or CH+. In chapter 3 we present new strategy to stabilize B2H4 in planar configuration using transition metal fragments. This requires the metal to donate two electrons into the empty B-B π orbital. Such complexes present a unique case study to the classical DCD model of metal-π complex. In chapter 4 we study the bonding in some recently synthesized metallaboranes which does not follow conventional electron counting rules. The complex and non-canonical nature of these metallaboranes feature some unique bonding patterns which are elucidated using theoretical techniques. In the final chapter we present new approach to build metal coated boron fullerenes. We use electron counting rules to device new structures which show enhanced metal boron bonding.

Abstract:
This chapter examines the connections between the Miller Grove community of free Blacks and the Underground Railroad. Established in 1844, Miller Grove is a cluster of rural farmsteads named for Bedford Miller, whose family stood among the sixty-eight people who received their freedom from one of four White families in south-central Tennessee. Primary archaeological excavations at Miller Grove took place at the farmstead of William Riley Williams, a free-born African American from Tennessee. Among the original migrants, former slaveholder Henry Sides and his wife lived among the freemen and freewomen at Miller Grove. This chapter begins with a discussion of how the American Missionary Association, through its missionary work, linked known Underground Railroad participants across the country. It then considers abolitionist strategies, particularly the dissemination of antislavery literature among African Americans. By tracing the history of Miller Grove, the chapter reveals distinct details of community formation and interracial cooperation within regional Underground Railroad operations.

Full text
Abstract:
Jonas of Bobbio, writing in the mid-seventh century, was not only a major Latin monastic author but also a historic figure in his own right. Born in the ancient Roman town of Susa in the foothills of the Italian Alps, he became a monk of Bobbio, the monastery founded by the Irish abbot Columbanus, soon after the saint’s death. He became archivist and personal assistant to successive Bobbio abbots, traveled to Rome to obtain the first papal privilege of immunity, and served as a missionary on the northern borderlands of the Frankish kingdom, where he wrote his Vita Columbani, one of the most influential works of early medieval hagiography. As abbot of a community in the far north of the Frankish kingdom, Jonas was part of an extensive monastic network that stretched from the English Channel to the Italian Apennines. By the time of Jonas’s death toward the end of the seventh century, the monastic landscape of this region had been transformed. This was the result of a socioreligious revolution, initiated by Columbanus (d. 615) and continued by his Frankish disciples in the decades after his death. Columbanus established a cluster of monasteries in the Vosges forests of Burgundy in the last decade of the sixth century, chief among them Luxeuil. During the seventh century, Luxeuil, its abbots, and the Merovingian royal court in Paris spearheaded an unprecedented monastic movement in Merovingian Gaul that would transform the interrelationship between religious and secular authorities in the Early Middle Ages.

Abstract:
Boron-based materials (i.e., boron and its borides) are mostly semiconductors with complex structures. These structures are characterized by an arrangement of an icosahedral cluster of B12 atoms [1]. The complexity of the crystal structure gives boron-based material a high melting point and low thermal conductivity at high temperature. On the other hand, the Seebeck coefficients and electrical conductivities of most bulk boron-based materials increase as temperature increases. Therefore, bulk boron-based materials are good candidates for high-temperature thermoelectric applications [2]. Due to the unique properties of bulk boron-based materials, one-dimensional nanostructures of boron-based materials have also attracted much attention, and various boron-based nanostructures have been synthesized recently [3]. These boron-based nanostructures are projected to be promising materials for novel nanoelectronic and nanoelectro-mechanical devices, as well as high temperature thermoelectric materials. However, compared to the extensive studies of carbon nanotubes and silicon nanowires, little has been done on the property characterization of boron and boride nanostructures.
