OBJECTIVE: To visualize tumor angiogenesis using the MRI contrast agent, Gd-DTPA-anti-VEGF receptor 2 antibody conjugate, with a 4.7-Tesla MRI instrument in a mouse model. MATERIALS AND METHODS: We designed a tumor angiogenesis-targeting T1 contrast agent that was prepared by the bioconjugation of gadolinium diethylen…
Aminopolycarboxylate (APC) ligands have been selected to prepare seven new heterobimetallic barium-cobalt complexes as molecular precursors for BaCoO3-δ oxide materials. The use of APC = nitrilotriacetate (nta3−), ethylenediaminetetraacetate (edta4−), cyclohexane-1,2-diaminetetraacetate (cdta4−) and diethylenetriamine…
A simple freeze-smashing method is described to produce water-dispersible single-walled carbon nanotubes (SWCNTs). This is based on freezing SWCNTs in ice and then smashing it in a crusher. After the smashing process, SWCNTs are found to be dispersible in water without any addition of dispersant and destruction of the…
An intergranular corrosion is a main degradation mechanism of austenitic stainless steels for use in a nuclear fuel reprocessing plant. The intergranular corrosion is caused by the segregation of impurities to grain boundaries and the resultant formation of active sites. Extra High Purity (EHP) austenitic stainless st…
nanostructured thin films were prepared by electrochemical anodization of zirconium films deposited by sputtering on silicon substrate. The influence of the electrolyte composition upon morphology of the nanostructured oxide was studied. The structure and the morphology of zirconium films (before and after anodization…
The combination of fluorescent and magnetic properties in single nanosystems is of current interest for applications in the biomedical and biological sciences, including drug delivery, and cell separation and labelling procedures. These nanocomposite particles are generally synthesised using high-temperature procedure…
Surface grafting of photosensitive polymer brushes on a flexible polymer surface was performed using Ar ion irradiation, which generated peroxides on the polymer surface upon exposure to air. These peroxides were utilized as initiators for graft polymerization of a photosensitive diazoketo-functionalized methacrylate…
Isolated nanometric objects of the nickel-iron cyanide-bridged coordination network are obtained by a sequential growth on "molecular seeds" anchored on Si(100) surfaces. Control of the density and the size of the nano-objects is achieved by imposing a growth process without side nucleation.
In this paper, we demonstrate the electrochemical synthesis of a copolymer of -phenylsulfonyl pyrrole (PSP) with 3,4-ethylenedioxythiophene (EDOT) as thin films on single carbon fiber microelectrodes. The deposition conditions on carbon fiber and the influence of monomer concentrations on the copolymerization were sho…
Open cell aluminum foams are metal cellular structures with a large volume fraction of pores. Due to their high stiffness to weight ratio, they are commonly used in applications for energy absorption and mechanical damping. The stiffness of the aluminum foam was increased by a nanocrystalline nickel coating via an ele…
The morphology of blends of poly(acrylonitrile-co-butadiene-co-styrene) (ABS) and poly(ethylene terephthalate glycol) (PET-G) has been investigated with special reference to the effect of blend ratio and compatibilization. Scanning electron microscopy (SEM) examination revealed different morphologies such as dispersed…
Titanium dioxide nanoparticles were synthesized in an aqueous solution. They were dispersed into an epoxy polymer matrix (commercially available under the trade name Araldite 5808) using a planetary mixer. Nanocomposite materials were prepared with several weight loadings of nanoparticles. In this work we investigate…
Solution crystallization is an essential part of processes in the chemical and pharmaceutical industries and a major step in physiological and pathological phenomena. Crystallization starts with nucleation and control of nucleation is crucial for the control of the number, size, perfection, polymorphism and other char…
Highly conductive buckypaper-gold nanoparticles composites have been prepared by the in situ electroless deposition of gold nanoparticles during the filtration that resulted in increases in conductivities of up to 684% at very low gold content.
Radiofrequency discharge of helium gas at low pressure was employed to modify surface properties of polycarbonate. The effects of process parameters on wettability and plasma etching were determined by monitoring surface energy and weight loss, respectively. Quadratic equations for surface energy and weight loss, in t…
One-dimensional (1D) nanostructures of semiconductor oxides are of interest for various applications including gas sensors. For gas sensors, nanostructures have advantages of improved gas-sensing characteristics and have potential in fabrication of miniature sensor. In this paper, we review some of the work done in ou…
Recently, several important structures have been solved using micro‐crystallographic techniques that previously could not have been solved with conventional crystallography. At GM/CA‐CAT we continue to develop micro‐crystallographic capabilities for difficult problems such as small crystals of large macromolecular com…

After a brief introduction to biomaterials and cell therapy, examples of the use o…
Some peculiarities of the time and temperature dependences of the high-temperature oxidation of a low-alloyed low-carbon steel covered with a glass coating are studied. The dependences characterizing the oxidation of steel without coating and that covered with it are found to have a similar character. Based on the dat…
