Ultraviolet (UV) photoconductive sensors were fabricated using an aluminium (Al)-doped zinc-oxide (ZnO) nanorod array with a diameter between 40 and 150 nm and thickness of approximately 1.1 µm. The nanorod arrays were prepared using a sonicated sol–gel immersion and annealed at 500 °C under different ambient conditio…
ABSTRACT Effects of low‐density polyethylene (LDPE) packaging and nano‐structured silver‐polyethylene (PE/Ag 2 O) packaging on the overall sensory quality, color, weight and solute loss of fresh‐cut apples stored at 5 and 15C were studied in this research. Results showed that, compared with normal LDPE packaging, the…
Colossal ionic conductivity was recently discovered in YSZ/SrTiO3 multilayers and was explained in terms of strain- and interface-enhanced disorder of the O sublattice. In the present paper we use a combination of scanning transmission electron microscopy and electron energy loss spectroscopy (EELS) and theoretical EE…
Linear alkyl benzene sulfonic acid (L) and three of its ester derivatives (L1, L2, L3) were prepared, followed by quaternization of these esters (L1Q, L2Q, L3Q). The corrosion inhibition effect on carbon steel in 1 M HCl was studied using weight loss and potentiodynamic polarization measurements. The adsorption of the…
Density functional theory (DFT) has become a general tool to investigate the structure and properties of complicated inorganic molecules, such as lanthanide(III) coordination compounds, due to the high accuracy that can be achieved at relatively low computational cost. Herein, we present an overview of different succe…
Carbon nanotubes are molecular-scale one-dimensional manufactured materials which display several potential applications in engineering and materials science. Burgeoning evidence demonstrates that carbon nanotubes and asbestos share comparable physical properties. Therefore carbon nanotubes might display toxic effects…
We have analyzed the structural and optical properties of Si implanted with very high Ti doses and subsequently pulsed-laser melted (PLM). After PLM, all samples exhibit an abrupt and roughly uniform, box-shaped Ti profile, with a concentration around 2 × 1020 cm−3, which is well above the Mott limit, within a 150 nm…
An innovative approach for cancer therapy implies the use of drugs covalently conjugated to macromolecular carriers that specifically target molecules over-expressed on tumor cells. This drug delivery strategy may allow a controlled release of the drug and a high targeting selectivity on tumor cells, increasing drug c…
Article Strategies for fracture toughness, strength and reliability optimisation of ceramic-ceramic laminates was published on June 1, 2011 in the journal International Journal of Materials Research (volume 102, issue 6).
Based on first-principles calculations, the magnetoelectric effect and the critical thickness for ferroelectricity in Co/BaTiO3/Co multiferroic tunnel junctions were investigated. The calculated results show that the ferroelectricity of multiferroic tunnel junctions can be maintained until a critical thickness of 1.6…
BACKGROUND: The purpose of this study was to develop folate-poly (PEG-cyanoacrylate-co-cholesteryl cyanoacrylate) (FA-PEG-PCHL)-modified freeze-dried liposomes for targeted chemotherapy using docetaxel as a model drug. METHODS: FA-PEG-PCHL was synthesized and its cytotoxicity was evaluated by CCK-8 assay in L929. Doce…
Abstract The rapidly increasing research interest in nanodevices, including nanoelectronics, nano‐optoelectronics, and sensing, requires the development of surface‐patterning techniques to obtain large‐scale arrays of nanounits (mostly nanocrystals and/or nanoparticles) on a silicon substrate. Herein, we demonstrate a…
We report the use of chalcogenidometallate clusters as a solution-processable precursor to SnSe2 for phase change memory applications. This precursor is spin-coated onto substrates and then thermally decomposed into a crystalline SnSe2 film. Laser testing of our SnSe2 films indicate very fast recrystallization times o…
Understanding the sorption process in natural zeolite and bentonite is necessary for effective utilization of these minerals as nutrient adsorbents and on the other side for controlling release of plant nutrients. This research was undertaken to characterize the ability of natural zeolite and bentonite minerals to ads…
The present research work deals with fabrication of indomethacin loaded gelatin nanoparticles prepared by double desolvation method for controlled drug delivery. Submicron polymeric particles with size < 800 nm were produced possessing narrow polydispersity index (< 0.5). Entrapment efficiency varied from 27-38% depen…
OBJECTIVE: Interest exists for early monitoring of worker exposure to engineered nanomaterials. Here, we highlight quantitative systemic markers of early effects after carbon nanotube (CNT) exposure. METHODS: Mice were exposed by pharyngeal aspiration to 40-μg CNT and harvested 24 hours, 7 days, and 28 days postexposu…
Abstract Natural zeolites have traditionally been used as supplements in animal nutrition with positive effects in terms of either faster growth or reduced incidence of diseases and death. The discovery that natural zeolites may act as drugs or coadjutants in pharmaceutical preparations has greatly enlarged the field…
Relatively little investigation has previously been done on the effects of aging on conductor surface conditions, or on the ac corona discharges from these conductors. In the present work these were investigated by means of comparing corona on typical aged conductors with that on new ones. The aged conductors from the…
Encapsulant materials used in photovoltaic (PV) modules serve multiple purposes. They physically hold components in place, provide electrical insulation, reduce moisture ingress, optically couple superstrate materials (e.g., glass) to PV cells, protect components from mechanical stress by mechanically decoupling compo…
β–Naphthalene sulphonic acid (β–NSA) doped polyaniline (PANI)–flyash (FA) composites have been prepared by chemical oxidative polymerization route whose conductivity lies in the range 2.37–21.49 S/cm. The temperature dependence of electrical conductivity has also been recorded which shows that composites follow Mott's…
