Titanium and stainless steel substrates were modified by grafting with mercaptododecylphosphonic acid (MDPA) followed by reaction with silver nitrate (AgNO3), in order to investigate the potential of phosphonate self-assembled monolayers functionalized by silver thiolate species as antibacterial nanocoatings for inorg…
We report here the donut-shaped nanostructure formation from the self-assembly of a designer lipid-like amphiphilic cone-shaped peptide. The critical aggregation concentration was measured using dynamic light scattering in water and phosphate-buffered saline. The dynamic self-assembly of the peptide was also studied u…
We explore the correlation between localized surface plasmon resonance (LSPR) of triangular Ag nanoparticles, molecular resonance, and the surface-enhanced resonance Raman excitation profile of molecules adsorbed on these nanostructures. Ag nanoparticles with various LSPRs were fabricated with nanosphere lithography (…
A crossover of the field-cooled magnetization from positive to negative has been observed below the magnetic ordering temperature (17.9 K) in a multimetal Prussian Blue analogue (PBA), Cu_{0.73}Mn_{0.77}[Fe(CN)_{6}].zH_{2}O. The reverse Monte Carlo (RMC) modeling (using the program RMCPOW) has been used to derive the…
New hydroxypropyl methylcellulose (HPMC)-lipid edible composite films containing low-toxicity chemicals with antifungal properties were developed. Tested chemicals were mainly salts of organic acids, salts of parabens, and mineral salts, classified as food additives or generally recognized as safe (GRAS) compounds. Se…
ZnO is a metal oxide material which possesses versatile properties and applications. Therefore, the target-oriented preparation of ZnO has become a major issue. Many preparation techniques involve bottom-up methods from precursor solutions. In the current contribution, a special precursor system is described that enab…
Here we report the preparation of Eu 3+ -doped cubic NaYF 4 and hexagonal Na(Y 1.5 Na 0.5 )F 6 nanocrystals and the crystal phase is modified by temperature of heating and varying the Y 3+ /F − ratio. The volume fraction of the cubic phase decreases from 100 to 55% with increasing the temperature from 80 to 400 °C, an…
Colloidal gold bipyramids with a narrow ensemble plasmon resonance in the near-infrared are adhered on glass or silicon substrates using polyelectrolytes. Atomic force microscopy and scanning electron microscopy show a monolayer of the deposited colloids that remains nonaggregated, with an optical density of ∼0.1 at t…
Photocontrol of Bcl-x(L) binding affinity has been achieved by using short BH3 domain peptides for Bak(72-87) and Bid(91-111) alkylated with an azobenzene crosslinker through two cysteine residues with different sequence spacings. The power to control the conformation of the crosslinker and hence peptide structure was…

The effect of short-chain branching (SCB) on the persistence length l p of polyethylene (PE) was studied using small-angle neutron scattering (SANS). In thermodynamically good solvents, l p can be measured directly from the scattering vector q tr at the crossover from good solvent mass-fractal scaling to the rodlike p…
Supramolecular polymers are chains of small molecules held together through reversible noncovalent interactions. In general, a given monomer self-assembles into a single type of supramolecular polymer. However, in a few cases, two different self-assembled structures can coexist; this yields interesting responsive syst…
PURPOSE: In vivo evaluation of good manufacturing practice-grade targeted liposomal doxorubicin (TVT-DOX), bound to a CD13 isoform expressed on the vasculature of solid tumors, in human tumor xenografts of neuroblastoma, ovarian cancer, and lung cancer. EXPERIMENTAL DESIGN: Mice were implanted with lung, ovarian, or n…
The Protein Structure Initiative Structural Genomics Knowledgebase (PSI SGKB, http://kb.psi-structuralgenomics.org) has been created to turn the products of the PSI structural genomics effort into knowledge that can be used by the biological research community to understand living systems and disease. This resource pr…
We study the feasibility of the alkali-metal (AM = Li, Na, K)-doped B 80 fullerenes for hydrogen storage using first-principles calculations. It is found that the AM atoms are strongly attached at the centers of the pentagons of the B 80, forming B 80 AM m complexes (1 ≤ m ≤ 12). This bonding can be attributed to the…
Dehydration of the Prussian blue analogues CsNi[Cr(CN)(6)] x 2 H(2)O (1) and Cr(3)[Cr(CN)(6)](2) x 10 H(2)O (2) affords two new microporous magnets: CsNi[Cr(CN)(6)] (1d) and Cr(3)[Cr(CN)(6)](2) x 6 H(2)O (2d). Compounds 1d and 2d maintain the Prussian blue structure, and N(2) adsorption measurements at 77 K show them…
Recent experimental and theoretical studies of the magnetoelectric (ME) effect in the nanocomposite structures and in laminates show an enhanced ME coefficient. These materials combine piezoelectric properties of the paramagnetic phase and piezomagnetic properties of the magnetic phase. We propose to fabricate heteros…
The nucleation and growth of palladium clusters supported on anatase TiO 2 (101) surface has been studied using periodic supercell models and density functional theory. The most active site for single Pd adatom on the perfect TiO 2 (101) surface is the bridge site formed by two two-coordinated oxygen (2cO) atoms at th…
The supramolecular interactions are of importance for inducing the molecular orientation and constructing functional materials with high performance. In this manuscript we report uniaxially oriented molecular crystal of a cyano substituted oligo( p -phenylene vinylene) 1,4-bis(α-cyano-4-diphenylaminostyryl)-2,5-diphen…
The kinetics and microstructure of solid-phase crystallization under continuous heating conditions and random distribution of nuclei are analyzed. An Arrhenius temperature dependence is assumed for both nucleation and growth rates. Under these circumstances, the system has a scaling law such that the behavior of the s…
