The synthesis of α,ω-difunctional monomers from the renewable resource oleyl alcohol via a cross-metathesis reaction with methyl acrylate is described. The reaction conditions were optimized for high conversions in combination with high cross-metathesis selectivity. The introduction of a protecting group for the alcoh…
The use of cardanol, a renewable natural resource, in place of a phenol or diphenol, in the synthesis of two different epoxy systems has been studied in this work. Cardanol, prepared by the distillation of cashew nut shell liquid (CNSL), was epoxidised using epichlorohydrin in presence of caustic soda catalyst at diff…
Quantitative proteomics has become a pivotal tool that has been applied to the investigation of many different biological processes such diverse as the detection of biomarkers in tissue samples, the regulation of cell signaling, and the characterization of protein interactions. Stable isotope labeling techniques have…
Titanium dioxide thin films were grown on layers by atomic layer deposition. The stabilizing effect of the bottom rutile-type layer resulted in growth of the rutile films at temperatures above . Stabilization of the rutile phase occurred due to local epitaxial growth of the polycrystalline structure, as revealed by tr…
Eight new coordination polymers, namely [Ni(L1)(BIE)] (1), [Cu(L1)(BIE)] (2), [Cu(L2)(BIE)] (3), [Co(L3)(BIE)] (4), [Cu(L4)0.5(BIE)] (5), [Co2(L4)(BIE)2]·H2O (6), [Cu5(L5)4(μ3-O)2(BIE)2(H2O)2] (7) and [Cu3(L6)2(BIE)2(H2O)3] (8), where L1 = p-phthalate, L2 = o-phthalate, L3 = oxalate, L4 = 1,2,4,5-benzenetetracarboxyla…
In our efforts to tune the structures of AgI complexes by ligand modification, six structurally related ligands: 1,2-bis(triazol-1-ylmethyl)benzene (L1), 1,3-bis(triazol-1-ylmethyl)benzene (L2), 1,4-bis(triazol-1-ylmethyl)benzene (L3), 1,3,5-tri(triazol-1-ylmethyl)-2,4,6-trimethylbenzene (L4), 1,4-bis[3-(2-pyridyl)-py…
It has been demonstrated previously that -stabilized electrodes [ , , , ] can provide anomalously high electrochemical capacities if charged to high potentials . High-voltage charging results in an irreversible capacity loss on the initial charge/discharge cycle; it also damages the electrode surface, leading to a hig…
The geometries of metal clusters and supramolecular architectures that contain nine metal atoms are analyzed within the framework of continuous shape measures (CShM). The most common polyhedra in nine coordinate complexes, the capped square antiprism and the tricapped trigonal prism, are also found among these familie…
N-doped TiO2 (anatase) with high visible light photoactivity was obtained by the thermal treatment of nanotube titanic acid (denoted as NTA) in an NH3 flow and investigated by means of X-ray diffraction (XRD), transmission electronic microscopy (TEM), diffuse reflectance spectra (DRS), X-ray photoelectron spectroscopy…
Two novel (3,12)-connected, chiral porous coordination polymers featuring 3D intersecting pore structures, selective sorption and solvothermal resistance properties are constructed by linking 3-connected benzene-1,3,5-tribenzoic acid with two types of 12-connected heptanuclear metal carboxylate clusters.
Crystalline α - Fe 2 O 3 with different particle shapes and sizes was selectively synthesized by a simple hydrothermal method. By carefully tuning the concentration of the reactants and the reaction time, α - Fe 2 O 3 cuboid particles and nanowires can be obtained. Based on the evidence of electron microscope images,…
We used CdSe/ZnS quantum dots-ssDNA-fluorescent dye conjugates as bioprobes to detect micrococcal nuclease with high specificity and sensitivity, and further utilized the bioprobe to monitor the micrococcal nuclease activity in the culture medium of Staphylococcus aureus by fluorescence microscopy.
Docetaxel, a widely used anticancer agent, has sparingly low aqueous solubility, thus Tween 80 and ethanol need to be added into its formulation, probably resulting in the toxic effects. In this study, we aimed to utilize submicron lipid emulsions as a carrier of docetaxel to avoid these potential toxic vehicles. Pref…
A heteroditopic receptor having crown ether and trifluoroacetylcarboxanilide groups selectively recognizes both potassium and cyanide ions in acetonitrile with an association constant of as high as Ka = 1.9 x 10(7) M(-1) through a highly cooperative ion-pair interaction, resulting in two orders of magnitude enhancemen…
Two isomorphous Co(II) and Mn(II) three-dimensional coordination polymers with tetrazolate-5-carboxylate as magnetic mediator exhibit an unprecedented 3,4-connected self-penetrating net topology; a combination of canted antiferromagnetism and metamagnetism was observed in the Co(II) compound, whereas the Mn(II) compou…
Orthopedic medical devices have been extremely successful in restoring mobility, reducing pain, and improving the quality of life for millions of individuals each year. Their success is reflected in the worldwide biomaterials market, in which orthopedic devices dominated sales at approximately $14 billion in 2002. Of…
The deterioration of the mechanical properties of yield strength and modulus of elasticity is considered as the primary element affecting the performance of steel structures under fire. In this study, hot-rolled S220 and S420 reinforcement steel rebars were subjected to high temperatures to investigate the fire perfor…
Life has evolved an extraordinary capacity to deal with the most extreme physical and chemical conditions. Extremophilic (extreme-loving) organisms have been found in the superheated waters of deep ocean vents or the hypersaline and cold lakes of Antarctica and indeed often require the extreme conditions of their habi…
In this paper, we analyze in detail the characteristics of surface electromagnetic modes that can propagate along a periodically corrugated, perfectly conducting wire. We show how these modes, termedspoofsurfaceplasmonpolaritons, resemble surface plasmon polaritons supported by metallic wires at optical frequencies. T…
One of the main obstacles to development of more effective passive fire protection for transportation is the lack of a quantitative understanding of the relations between the results of various materials fire tests used in this field. The need for multiple testing techniques arises from the complexity of fire phenomen…
