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…
New heterobimetallic tetranuclear complexes of formula [Fe(III){B(pz)(4)}(CN)(2)(μ-CN)Mn(II)(bpy)(2)](2)(ClO(4))(2)·CH(3)CN (1), [Fe(III){HB(pz)(3)}(CN)(2)(μ-CN)Ni(II)(dmphen)(2)](2)(ClO(4))(2)·2CH(3)OH (2a), [Fe(III){B(pz)(4)}(CN)(2)(μ-CN)Ni(II)(dmphen)(2)](2)(ClO(4))(2)·2CH(3)OH (2b), [Fe(III){HB(pz)(3)}(CN)(2)(μ-CN…
The structural, electronic, elastic and some thermodynamic properties of the cubic C15 structure ZrV2 compound under pressure are investigated by first-principles calculations. Our results for the equilibrium unit cell volume, bulk modulus and band structure are consistent with the calculated and experimental results.…
Using Brillouin and Raman scattering and NMR techniques, we have investigated the elastic and structural properties of four post-shocked specimens of borosilicate glass, recovered from peak pressures of 19.8, 31.3, 40.3, and 49.1 GPa. The Raman spectra of shock-wave compressed borosilicate glass for peak pressures of…
Spiders employ clever behavioral strategies combined with almost invisible custom-made adhesive silk fibers to spin prey capture webs. The adhesives used in these webs evolved over millions of years into a class of natural materials with outstanding properties. Here, we review how spiders use different adhesives to ca…
Article Phase-field approach to martensitic phase transformations: Effect of martensite–martensite interface energy was published on June 1, 2011 in the journal International Journal of Materials Research (volume 102, issue 6).
Abstract Recently, the display of liquid crystal having the blue phase have been studied more intensively because it has many merits such as wide viewing angle without compensation films, very fast switching response time, and no need for the alignment layer and the rubbing process. First, we confirmed the feasibility…
We have used pulsed laser deposition to fabricate graphene on catalytic nickel thin film at reduced temperature of 650 °C. Non-destructive micro-Raman spectroscopic study on our samples, measuring 1x1 cm2 each, has revealed few-layer graphene formation. Bi-, tri-, and few-layer graphene growth has been verified by Hig…
Silver sulfide, Ag 2 S, is most commonly known as the tarnish that forms on silver surfaces due to the exposure of silver to hydrogen sulfide. The mineral acanthite is a monoclinic crystalline form of Ag 2 S that is stable to 176°C. Upon heating above 176°C, there is a phase conversion to a body-centered cubic (bcc) f…
BACKGROUND: Superparamagnetic iron oxide nanoparticles have been used in clinical applications as a diagnostic contrasting agent. Previous studies showed that iron oxide nanoparticles deposited in the liver and spleen after systemic administration. The present study investigated the effect of iron oxide nanoparticles…
In this work, the degradation process of natural ester-based insulating fluids was evaluated through laboratory aging tests. Two distinct aging methodologies were used: natural ester-based insulating fluids were placed in sealed flasks at 120°C in the presence of Kraft insulating paper containing about 1.5 and 5 wt% m…
