Hybrid MRI nanoprobes, immunotargeted to the La ribonucleoprotein, which becomes available for binding in the cytoplasm of post-apoptotic permeable cells, are designed for the improved detection of apoptotic tumor cells. The high level of specificity achieved through the use of an optimal polyethyleneglycol interlayer…
Thin films of well‐crystallized pure rutile nanorods were deposited on Ti substrates through a simple solution approach at a low temperature of 353 K. Field emission scanning electron microscopic and atomic force microscopic investigations revealed topographies of both quasi‐aligned and less‐aligned nanorod arrays, de…
An experimental study of acoustic emission (AE) in a single crystal and in a polycrystalline sample of ${\text{Fe}}_{68.8}{\text{Pd}}_{31.2}$ is presented. The samples are studied in a temperature range that is known to include not only a martensitic transition (MT) but also premartensitic effects and strong lattice-p…
Films of cylinder-forming polystyrene- block -poly(methyl methacrylate) (bulk intercylinder spacing a o ) were directed to assemble on surfaces chemically patterned with a hexagonal array of spots (interspot spacing a s ). The block copolymer domain assembly was investigated as a function of the film thickness and the…
A detailed study of polysiloxane nanofiber formation by surface initiated polymerization of vapor phase organotrichlorosilane reagents is presented. Substrate composition, substrate activation, reagent quantity, reaction pressure, and reaction time are parameters shown to influence nanofiber synthesis. Stepwise variat…
Topographic engraving of structures in polymer surfaces attracts widespread interest for application in imprint lithography and data storage. We study the nonlinear interaction of nanoindents written in close proximity, 20-100 nm, to one another in a highly cross-linked polystyrene matrix. The indents are created ther…
Long‐term durability of ceramic composites requires the retention of weak interfaces to promote crack deflection and subsequent sliding at the fiber–matrix boundary. The present article addresses the efficacy of fugitive carbon coatings in achieving this goal in all‐oxide systems. A solution precursor route with a low…
The morphology of thin films of sphere-forming block copolymers on striped chemically patterned surfaces was investigated as a function of thickness and commensurability of the pattern period ( L s ) and the lattice spacing of the spherical structure ( L o ), using scanning electron microscopy and atomic force microsc…
Abstract The polycondensation of bis(hydroxyethylene) terephthalate and its oligomers to PET catalyzed by different chelated and non‐chelated titanium catalysts in a lab‐scale stirred‐tank reactor and differential scanning calorimeter were investigated. Different titanium compounds showed different activity and select…
Two different strategies for the preparation of active dimethyl ether catalysts are evaluated using CuO−ZnO−Al 2 O 3 and SiO 2 −Al 2 O 3 as methanol synthesis and methanol dehydration catalysts components, respectively. Composite catalysts are prepared by mixing of the two freshly precipitated catalyst precursors and…
A novel nanostructured hybrid PMMA/MgAl-LDH thin film enables a strong UV-blocking effect, up to 97% below 300 nm, and excellent visible transparency. The graft density of PMMA films can be controlled by adjusting the area coverage of immobilized LDH monolayer with a highly-orientated structure on oxide, metal, and po…
A nanoporous biodegradable elastomer based on citric acid is described. Nanopores are used to control the mechanical and degradation properties of the elastomer. Furthermore, macromolecular drugs can be entrapped under mild conditions via pore collapse, which also delays the release of the drug. The nanoporous elastom…
Abstract Multilayer composites that utilize polymeric and brittle inorganic films are essential components for extending the lifetimes and exploiting the flexibility of many electronic devices. However, crack formation within the brittle inorganic layers that arise from defects as well as the flexing of these multilay…
The technological advances predicted (or, perhaps, demanded) for the twenty-first century are intimately linked to the crystallochemically controlled synthesis of high-performance functional materials. To answer the new hendiatris of ‘smaller, faster, better’, the manufacture of these materials as nanoparticles has be…
Abstract Tapioca starch (TS), poly(lactic acid) (PLA), and Cloisite 30B nanocomposite foams, with four clay contents of 1, 3, 5, 7 wt%, were prepared by a melt‐intercalation method. Selected structural, thermal, physical, and mechanical properties were characterized using X‐ray diffraction, scanning electron microscop…
Uniform single-crystalline indium hydroxide microcubes can be successfully synthesized in large quantities via a convenient hydrothermal route using hydrated indium nitrate and sodium borohydride as reagents under mild conditions. The morphology and size of indium hydroxide microcubes can be controlled by varying the…
Folate-conjugated polymer micelles poly(D,L-lactide-co-glycolide)-poly(ethylene glycol)-folate (PLGA-PEG-FOL) was fabricated to encapsulate anticancer drug doxorubicin for targeting delivery to cancer cells with overexpression of folate receptors. To increase therapeutic effect, D-alpha-tocopheryl polyethylene glycol…
The orientation of microdomains in block copolymer thin films is controlled by two simple strategies that have been developed through controlling interfacial interactions by anchoring end-functionalized polymers to the substrate. Combined with solvent annealing, these methods provide a simple route for manipulating th…
Corrosion behaviour of biomedical alloys is generally determined in mineral electrolytes: unbuffered NaCl 0.9% (pH 7.4) or artificial saliva (pH 6.8). The assays with exclusive utilization of these electrolytes are of low relevance for the biological condition, to which the alloys will be exposed once implanted in the…
Abstract This article discusses the preparation and characterization of CaTiO 3 filled PTFE flexible laminates for microwave substrate applications. Single phase CaTiO 3 filler composition was prepared through solid‐state ceramic route. Phase formation was confirmed by powder X‐ray diffraction studies. Morphology and…
