We report that two-dimensional (2D) sub-diffraction-limited images can be theoretically reconstructed by a new metamaterial far-field superlens. The metamaterial far-field superlens, composed of a metal-dielectric multilayer and a one-dimensional (1D) subwavelength grating, can work over a broad range of visible wavel…
We have studied the line shape and frequency of the G band Raman modes in individual metallic single walled carbon nanotubes (M-SWNTs) as a function of Fermi level (epsilonF) position, by tuning a polymer electrolyte gate. Our study focuses on the data from M-SWNTs where explicit assignment of the G- and G+ peaks can…
The growth of monocrystalline diamond films of electronic quality and large thickness (>few hundreds of microns) is an important issue in particular for high-power electronics. In this paper, we will describe the different key parameters necessary to reach this objective. First, we will examine the deposition process…
ZnO is a unique material that offers about a dozen different application possibilities. In spite of the fact that the ZnO lattice is amenable to metal ion doping (3d and 4f), the physics of doping in ZnO is not completely understood. This paper presents a review of previous research works on ZnO and also highlights re…
Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not only do not inhibit the asphaltene agglomeration,, they may also…
We describe a direct observation of the excitonic giant Zeeman splitting in ${\mathrm{Ga}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}\mathrm{N}$, a wide-gap III-V diluted magnetic semiconductor. Reflectivity and absorption spectra measured at low temperatures display the $A$ and $B$ excitons, with a shift under magnetic fiel…
The search for materials and systems, capable of operating long term under physiological conditions, has been a strategy for many research groups during the past years. Silicon carbide (SiC) is a material, which can meet the demands due to its high biocompatibility, high inertness to biological tissues and to aggressi…
The review is devoted to nanodiamond as a member of new nanocarbon allotropes. The past results related to the main features of detonation technology for producing nanodiamond are highlighted. Effects of technology on the structure of nanodiamond particles as well as functionalization of nanodiamond surface to chemica…
Flexible and transparent electronic devices with extremely high mobilities are fabricated from a graphene sheet, a single atomic layer of graphite, by using the transfer printing method. “Printed” graphene circuits achieve field effect mobilities of up to 10000 cm2/Vs at room temperature. Our printing technique is sca…
UNLABELLED: XtalPred is a web server for prediction of protein crystallizability. The prediction is made by comparing several features of the protein with distributions of these features in TargetDB and combining the results into an overall probability of crystallization. XtalPred provides: (1) a detailed comparison o…
The performance of methods for predicting protein-protein interactions at the atomic scale is assessed by evaluating blind predictions performed during 2005-2007 as part of Rounds 6-12 of the community-wide experiment on Critical Assessment of PRedicted Interactions (CAPRI). These Rounds also included a new scoring ex…
Nanodiamond materials can serve as highly versatile platforms for the controlled functionalization and delivery of a wide spectrum of therapeutic elements. In this work, doxorubicin hydrochloride (DOX), an apoptosis-inducing drug widely used in chemotherapy, was successfully applied toward the functionalization of nan…

Abstract Boron nitride nanotubes nucleation on the catalyst's surface after the formation of metal particle alloys oversaturated with boron and nitrogen atoms is the most important step for any type of the catalytic pro‐cesses of BN nanotubes formation. A thermodynamic analysis of the boron‐nitride nanotubes nucleatio…
A unique method for synthesis of multi-walled-carbon-nanotube- (MWCNT-) implanted copper composite spheres is reported. It involves Cu ions combining with functionalized MWCNTs at molecular level and formation of spheres after reduction, nucleation and growth of Cu ions attaching to the surface of MWCNTs. The MWCNT-im…
A new type of copolymer composed of l-histidine (ampholyte) and n-butyl methacrylate (hydrophobic moiety) was developed for the preparation of nonbiofouling surfaces. The copolymer adsorbed onto resin surfaces and made the surface very hydrophilic. The hydrophilization effect was higher than that of bovine serum album…
A red fluorescent zwitterionic molecule based on the diaminodicyanoquinodimethane framework is synthesized and structurally characterized. Formation of nanocrystals of this molecule through the reprecipitation protocol is followed by examining the optical absorption and emission. Computational modeling based on molecu…
Abstract The thermal conductance of nanotubes is examined over a wide temperature range and as a function of mechanical manipulation. It is found that carbon nanotubes maintain impressive thermal conductance up to their decomposition temperature of ∼3200 K. For both carbon and boron nitride multiwalled nanotubes the t…

Simultaneous electron spin resonance (ESR) and UV−vis−NIR measurements have been carried out during oxidation of a poly[ N -methyl(aniline)] (PNMA) film, which was prepared electrochemically in aqueous solutions containing 1 M trifluoroacetic acid. In situ conductance measurements were also performed during the electr…
