A new series of 12 complexes of cobalt(II) and nickel(II) with N-isonicotinamido-2',4'-dichlorobenzalaldimine (INH-DCB) with the general composition MX(2) . n(INH-DCB) [M = Co(II) or Ni(II), X = Cl(-) ,Br(-), NO(3) (-), NCS(-), or CH(3)COO(-), n = 2; X = ClO(4) (-), n = 3] have been synthesized. The nature of bonding and the stereochemistry of the complexes have been deduced from elemental anal...
Adhesive bonding community shows a continued interest in using bridging mechanisms to toughen the interface of secondary bonded joints, especially case laminated composites. Due snap-back instability that occurs during fracture, confusions may exist when identifying toughening effect experimentally. The true be overestimated by lumping all energy contributions (kinetic included) an overall effe...
Abstract The Devonian/Carboniferous Boundary (DCB) interval is associated with mass extinction, isotope excursions and a short glacial episode. This study investigates how boundary extinction environmental change expressed in the high-palaeolatitudinal record of Bolivian Altiplano (western Gondwana). A latest Devonian early Carboniferous section has been investigated using sedimentology, palyno...
Abstract The synthesis of both covalently bonded chlorine and nitrogen-doped carbon materials (Cl-N-CNMs) has been little studied. In this paper we report on the investigation Cl-N-CNMs using a feedstock containing mixture dichlorobenzene (DCB), acetylene acetonitrile over Fe-Co/CaCO 3 catalyst an injection CVD method at 800 °C. By varying acetonitrile:DCB concentration ratio (66.7:33.3; 33.3:6...
Complexes of the type {[(pyS)Ru(NH(3))(4)](2)-μ-L}(n), where pyS = 4-mercaptopyridine, L = 4,4'-dithiodipyridine (pySSpy), pyrazine (pz) and 1,4-dicyanobenzene (DCB), and n = +4 and +5 for fully reduced and mixed-valence complexes, respectively, were synthesized and characterized. Electrochemical data showed that there is electron communication between the metal centers with comproportionation ...
A series of carbon nanohorns (CNHs) constituted by the aggregation of about 2000 individual conical graphene tubes (diameters from 2 nm to 5 nm and a length of 40-50 nm) that have been modified with dyes of two, three, or four terthienyl groups has been prepared by adsorbing the corresponding dye on the CNH. Persistent inks in o-dichlorobenzene (o-DCB) of these dye-CNH conjugates were obtained ...
UNLABELLED Raw and cooked beef and pork loins were irradiated at 0 or 5 kGy. The radiation-induced marker compounds, such as hydrocarbons, 2-alkylcyclobutanones (2-ACBs), and sulfur volatiles, were determined after 0 and 6 mo of frozen storage. Two hydrocarbons (8-heptadecene [C(17:1)] and 6,9-heptadecadiene [C(17:2)]) and two 2-ACBs (2-dodecylcyclobutanone [2-DCB] and 2-tetradecylcyclobutanone...
Double-unit cord blood transplantation (DCBT) appears to enhance engraftment despite sustained hematopoiesis usually being derived from a single unit. To investigate DCBT biology, in vitro and murine models were established using cells from 39 patient grafts. Mononuclear cells (MNCs) and CD34(+) cells from each unit alone and in DCB combination were assessed for colony-forming cell and cobblest...
Engineering adhesive joints are being increasingly used in industry because of the advantages they offer over other joining methods such as fastening or welding. The development and the use of adhesives in a design environment require accurate mechanical tests in order to measure their strength and toughness. Standard techniques such as the shear lap test are commonly used to measure shear stre...
Governments often enact policies to incentivize consumers away from behaviors with negative externalities, at the expense of consumer convenience. Understanding the nonmonetary costs consumers face has implications for social welfare evaluation and policy design; however, quantifying these costs is not always feasible. In this paper, I precisely identify and measure a hidden time cost of an inc...
