Two-terminal devices were fabricated using unintentionally doped Zinc Oxide (ZnO) nanowires (NW) grown via a chemical vapor deposition technique to study the influence of surface functionalization on their transport properties. Organic molecules with differing functional groups demonstrated contrasting effects on the charge transport of the nanowires depending on the polarity and orientation of...

The study of zinc metabolism in experimental animals and humans is dependent upon a reliable analytical method. Numerous methods, gravimetric, turbidimetric, and calorimetric (l), have been tried and found wanting. Fischer (2) first introduced diphenylthiocarbazone (dithizone) for the analysis of metals with relation to industrial processes. This organic dye combines with a number of the heavy ...

This paper reviews effects of organic compounds for synthesis of ZnO by reflux method as well as systematic investigation on the relationship between the structures of organic compounds on ZnO nanostructures morphology. The characteristic results revealed that using different template not only prevent a drastic increase in the crystallite size of the zinc species but also provide suitable condi...

BACKGROUND Hoof lesions in sows have been associated with lameness and poor hoof horn quality. The mechanical strength and quality of hoof horn is determined by the density and diameter of horn tubules, which were recently associated with the severity of lesions on the hoof wall of sows. Histologic changes that have previously been described in cases of bovine laminitis, have also been observed...

Crystalline compounds built up of periodically ordered nanostructured inorganic semiconductor motifs and organic molecules are a new type of hybrid semiconducting materials that are of great fundamental importance and technological relevance. The most appealing feature of these materials is that many favorable properties of each individual component are brought into the hybrid structure by inco...

Five porous metal-organic frameworks based on linking zinc oxide clusters with benzene-1,4-dicarboxylate, naphthalene-2,6-dicarboxylate, 4,5,9,10-tetrahydropyrene-2,7-dicarboxylate, 2,3,5,6-tetramethylbenzene-1,4-dicarboxylate, or benzene-1,3,5-tris(4-benzoate) were synthesized in gram-scale quantities to measure their hydrogen uptake properties. Hydrogen adsorption isotherms measured at 77 K s...

We have utilized hybrid zinc oxide/silica microdisk lasers to sense volatile organic compounds, such as toluene and nitrobenzene. Nonspecific adsorption of these organic molecules onto the microdisk surface causes an increase in the disk refractive index, ultimately resulting in a redshift of the observed lasing wavelengths. The monitoring of these shifts provides the sensing modality. Microdis...

Zeolitic imidazolate frameworks of zinc, cobalt, and cadmium, including the framework ZIF-8 commercially sold as Basolite Z1200, exhibit surprising sensitivity to carbon dioxide under mild conditions. The frameworks chemically react with CO2 in the presence of moisture or liquid water to form carbonates. This effect, which has been previously not reported in metal-organic framework chemistry, p...

Organic thin-film solar cells with a conducting polymer (CP)/fullerene (C60) interpenetrating heterojunction structure, fabricated by spin-coating a CP onto a C60 deposit thin film, have been investigated and demonstrated to have high efficiency. The photovoltaic properties of solar cells with a structure of indium-tin-oxide/C60/ poly(3-hexylthiophene) (PAT6)/Au have been improved by the insert...
