We review recent experiments on the interaction of proteins with anionic polyelectrolytes in aqueous solution. Data from the literature demonstrate that proteins can form soluble complexes with linear polyelectrolytes even on the "wrong side" of the isoelectric point, that is, for pH values above the isoelectric point…
The hydrogened diamond like carbon film (DLCH) with 1 μm thickness is made by hydrocarbon gas ion beam deposition method. The relationship between ID⁄IG ratio fitted from visible Raman spectra and sp2/sp3 ratio done from XPS spectra of DLCH film shows a trend. The ID⁄IG ratio of deconvoluted visible Raman spectra show…
The remarkable properties of shape memory alloys have facilitated their applications in many areas of technology. The purpose of this paper is to present an overview of thermomechanical behavior of these alloys, discussing the main constitutive models for their mathematical description. Metallurgical features and engi…
The present study employs a tungsten tracer incorporated into the aluminum substrate to investigate the development of porosity in anodic alumina formed in phosphoric acid electrolyte. An unusual inversion of the tracer distribution is revealed as the tracer layer traverses the barrier region. Although initially incor…
This review covers recent advances in the wettability of aligned carbon nanotubes (ACNT). Carbon nanotubes (CNT) are inherently somewhat hydrophilic, with a water contact angle of less than 86°. When they are arranged in a textured manner on substrates having different surface topographies, different wettabilities are…
Ag/TiO2 core-shell nanowires were synthesized via a one-step solution method without using a template. Interestingly, the shell morphologies can be controlled to be smooth or bristled by altering the reaction temperature. Moreover, the TiO2 shell thickness and bristle length can be tuned by changing the AgNO3 concentr…
Nitrogen-containing carbon nanotubes (NCNT) are effective re-usable solid base catalysts, their activity for a Knoevenagel condensation being related to the amount of pyridinic nitrogen incorporated in the NCNT structure, which could be tuned by the synthesis parameters of the catalyst.
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…
