A disc-like heptanuclear Co(II)-cluster, [Co7(bzp)6(N3)9(CH3O)3].2ClO4.2H2O (1) (bzp = 2-benzoyl pyridine), mixed-bridged by 3/4 azides (mu1,1 and mu1,1,1) and 1/4 mu1,1,1-methanol, shows slow relaxation at static zero and non-zero fields below 6 K, towards single molecule magnet behavior.
Mechanical and morphological studies of aligned nanofibrous meshes of poly(epsilon-caprolactone) (PCL) fabricated by electrospinning at different collector rotation speeds (0, 3000 and 6000 rpm) for application as bone tissue scaffolds are reported. SEM, XRD and DSC analyses were used for the morphological characteriz…
Abstract Protein–protein interactions represent a highly populated class of targets for drug discovery. However, such systems present a number of unique challenges. This review presents an analysis of individual protein‐protein interaction systems which have recently yielded success in discovering drug‐like inhibitors…
Solid oxide fuel cells (SOFCs) are complex electrochemical devices that offer significant advantages over conventional power generation technologies. Many of these advantages surround the environmental impact of energy generation and in particular the efficiency of power production coupled with the potential range of…
We present a thermodynamic evaluation of the self-assembly of charged nanometer-sized particles at the water/oil interface. The chemical potentials of the nanoparticles in the bulk (aqueous) phase and at the water/oil interface are calculated taking into account interfacial energies, van der Waals interactions, and el…
The stability of the barrier layers of bilayer passive films that form on metal and alloy surfaces, when in contact with oxidizing aqueous environments, is explored within the framework of the point defect model using phase-space analysis, in which the rate of growth of the barrier layer into the metal ͑dL + /dt͒, and…
We report a method for producing thin, completely continuous and highly conductive copper films conformally inside very narrow holes with aspect ratios over 35:1 by atomic layer deposition (ALD). Pure copper thin films were grown from a novel copper(I) amidinate precursor, copper(I) -di-sec-butylacetamidinate, and mol…
A multiple switching fluorescent photochromic bisthienylethene bridged naphthalimide bearing cholesteryl groups was synthesized and its organogelator showed excellent photo-responsive and thermal reversible performance by light, thermal.
A highly active heterogeneous Fenton catalyst was fabricated by impregnating iron oxide nanoparticles in alumina coated mesoporous SBA-15 silica.
The 2006 edition of this authoritative guide on liquid crystalline polymer (LCP) science was produced in response to the wealth of new material generated in the field. It takes the reader through the theoretical underpinnings to real-world applications of LCP technology in a logical, well-integrated manner. A chapter…
The present study was aimed at developing and exploring the use of mannosylated dendritic architecture for the selective delivery of an anti-tuberculosis drug, rifampicin (RIF) to alveolar macrophages (AM). The mannosylated dendritic architecture was synthesized and characterized by using IR and NMR spectroscopy. RIF…
The magnetic interactions in organic diradicals, dinuclear inorganic complexes and ionic solids are presented from a unified point of view. Effective Hamiltonian theory is revised to show that, for a given system, it permits the definition of a general, unbiased, spin model Hamiltonian. Mapping procedures are describe…
One-third of drugs in development are water insoluble and one-half fail in trials because of poor pharmacokinetics. Block copolymer micelles are nanosized particles that can solubilize hydrophobic drugs and alter their kinetics in vitro and in vivo. However, block copolymer micelles are not solely passive drug contain…
Besides temperature at one atmosphere, the applied pressure is another important parameter for influencing and controlling reaction pathways and final reaction products. This is relevant not only for the genesis of natural minerals, but also for synthetic chemical products and technological materials. The present crit…
We use an interferometric detection scheme to directly detect single gold nanoparticles with a diameter as small as 5 nm in an aqueous environment. We demonstrate both confocal and wide-field detection of nanoparticles and study signal strength as a function of particle size. Furthermore, we demonstrate a detection sp…
Novel covalently porphyrin-functionalized single-walled carbon nanotubes (SWNTs) have been synthesized by the reaction of SWNTs with in situ generated porphyrin diazonium compounds. The resulting nanohybrid was characterized by spectroscopic (UV-Vis-NIR, FTIR and Raman) and microscopic (TEM and AFM) methods. The Raman…
A new perylene bisimide dye has been synthesized which self-assembles into columnar nanoaggregates and liquid crystalline mesophases with striking photoluminescent properties.
Abstract Enabled by their size and supramolecular structures, nanoparticles (that is, particles of approximately 10 to 100 nanometers) promise to be particularly capable agents in the detection, diagnosis, and treatment of cancer. When loaded with chemotherapeutic agents, nanoparticle delivery to cancerous tissues rel…
The theory of wetting on super-hydrophobic surfaces is presented and discussed, within the general framework of equilibrium wetting and contact angles. Emphasis is put on the implications of super-hydrophobicity to the prevention of biofouling. Two main lines of thought are discussed, viz. i) "mirror imaging" of the L…
We examine the feasibility of admittance spectroscopy (AS) and susceptance analysis in the determination of the charge-carrier mobility in an organic material. The complex admittance of the material is analyzed as a function of frequency in AS. We found that the susceptance, which is the imaginary part of the complex…
