We report that nucleotides disentangle and disperse multiwalled boron nitride nanotubes in aqueous solution via π–π stacking interactions. Quantum dot-boron nitride nanotube hybrid materials were produced by using guanosine 5′-monophosphate as a linking reagent. These hybrid materials are highly promising for biomedic…

We introduce a new approach that combines the self-assembly and seeding methods for silver plating of the proposed Fe2O3@Au-seed substrate. By adjusting the silver plating time between 0 and 360 s, the optical resonance of the substrates clearly varied from visible to near-infrared. To investigate the potential of the…
A novel interface-facilitated synthesis of metal-free graphitic carbon plates with controllable thickness is reported. In contrast to bulk phase synthesis of the conventional hydrothermal method, the process occurs only at the interface due to the enrichment of precursors induced by the organic intermediates, allowing…
Carbon nanotubes (CNTs), because of their superior mechanical, electrical, and thermal properties and possible low-cost, large volume production, have been projected as promising nanostructure additives in polymer composites to achieve tunable and enhanced materials properties. Transport properties of CNT-polymer comp…
Upon decreasing ultra-thin Ga16Sb84 films from 10 to 3 nm, the exponential increase in crystallization temperature and electrical resistance ratio are attributed to increased specific interface-energies and inhomogeneous interfacial strain at the interfaces. The specific interface-energies and strain also stabilize th…
A simple model of a raft made of spaced nano-cylinders is formulated and discussed, in order to improve the understanding of load-carrying capacity of insects and miniature devices that float on liquids. It is shown that mostly the outer cylinders of the raft determine the load-carrying capacity. Therefore, the raft p…
A study has been conducted to synthesize highly organosoluble and optically active poly(amide-imide)s via direct solution polycondensation of different aliphatic and aromatic diisocyanates with a chiral diacid monomer in the presence of molten tetrabutylammonium bromide (TBuAmBr) as a molten ionic liquid, and was comp…
In this study, aluminum was anodized in 0.4 M H 2 SO 4 + 0.145 M H 3 BO 3 solution by means of potentiostatic method. In first step, the most appropriate conditions (anodizing voltage and period) were determined. The voltage-current behavior was investigated between 0 to 30 V and oxide formation potential (15 V) was d…
Recent studies in our laboratories have demonstrated that a helical polypeptide (17H6), equipped with a histidine tag and a helical alanine-rich, glutamic-acid-containing domain, exhibits pH-responsive assembly behavior useful in the production of polymorphological nanostructures. In this study, the histidine tag in t…
The combination of synthetic liposomes or cell-derived biological vesicles with magnetic nanoparticles creates multifunctional nanovectors with promising potential for diagnosis and therapy. First, the magnetic properties exported from the nanoparticles to the vesicles make them efficient tracers for Magnetic Resonanc…
Influence of filler size on impact properties for polypropylene (PP)/elastomer/filler ternary composites was investigated. Calcium carbonate (CaCO3) particles with a diameter in the range from 120 to 1200 nm were used as a filler and polystyrene-block-poly(ethylene-butene)-block-polystyrene triblock copolymer (SEBS) w…
The ability of multiblock ABC terpolymers to self-assemble into multicompartment micelles in an A-selective solvent is of great current interest. We have used dissipative particle dynamics (DPD) to explore the morphologies adopted by a particular block terpolymer architecture, A2-star-(B-alt-C), where the two A blocks…
Amine-terminated poly (L-lactide) (NH 2 -PLLA) with various chain lengths were successfully synthesized by sequential tert-butyl- N -(3-hydroxypropyl) carbamate initiated bulk ring-opening polymerization (ROP) of L-lactide (L-LA) in the presence of Stannous(II) 2-ethylhexanoate (Sn(Oct) 2 ) and deprotection of the N -…
A series of oxadiazole-containing molecular hybrid materials with different structures (H1–H5) are controllably prepared by a hydrosilylation method based on the octahydridosilsesquioxane (POSS, T88HH). All these resultant hybrid materials are soluble in common organic solvents, such as chloroform, toluene, tetrahydro…
Poly(2-cinnamoyloxyethyl methacrylate)-block-poly(tert-butyl acrylate) (PCEMA-b-PtBA) formed cylindrical micelles in methanol, a selective solvent for PtBA. Photo-crosslinking the PCEMA core yielded structurally stable nanofibers. Hydrolyzing the coronal PtBA chains then produced nanofibers bearing surface carboxyl gr…
A set of four phenylalanine analogues experiences diffusion retardation when transferred from phosphate-buffered saline into a peptide hydrogel of the same pH and ionic strength. The extent of retardation increases linearly with logP(oct), their lipophilicity.
The excitation of multiple surface-plasmon-polariton (SPP) waves by the plane wave illumination of a metallic surface-relief grating coated with a sculptured nematic thin film (SNTF) was studied theoretically. The relevant boundary-value problem was formulated such that the grating plane and the morphologically signif…
In this study we propose a digital dermatoscopy method to measure the human skin roughness. By using this method we eliminate the use of silicon replica. Digital dermatoscopy consists of handheld digital microscope, image processing and information extraction of skin roughness level. To reduce the noise due to the var…
By using small-angle neutron scattering (SANS), we observed the upper critical solution temperature (UCST) behavior for a binary polymer mixture of polystyrene/poly(vinyl methyl ether) (PS/PVME) with a PS rich asymmetric composition. It was found in a single mixed state and upon decreasing the temperature below the gl…
