Fluorescent nanorods formed by self-assembly of hexaphenylbenzene derivative in the presence of cyanide ions serve as a sensitive colorimetric and fluorogenic sensor for the detection of trinitrotoluene (TNT) at the attogram (10(-18) g) level with a detection limit of 10.21 ppq (parts per quadrillion).

A simple selective etching process easily removed a 2nd anodized TiO(2) nanotubes (TNTs) layer from a physically stable 1st anodized TNTs layer to produce noncurling, freestanding, large-area aligned doubly open-ended TNTs. These TNTs were easily transferred to a conducting glass for use in fabricating front-illuminated dye sensitized solar cells.

Research in recent years has demonstrated that biological molecules such as enzymes, immunoglobulins, and other proteins can be immobilized in sol-gel derived matrices and retain their biological function. Development ofglasses with encapsulated biomolecules has opened the possibility of solid-state optical biosensors for the detection and measurement of desired analytes. In this work, we repor...

The results of the measurements 2,4,6-trinitrotoluene (TNT) vapor concentration over its trace amounts, called thin films, on glass surface with a 100 ng/cm2 in square area side 1 cm time are presented. amounts TNT were formed by applying solution acetonitrile diluted chemically pure acetone, followed evaporation solvents. In order to measure concentration, an EKHO-V-IDTS portable multibacillar...

A bacterial strain, Mycobacterium sp. strain HL 4-NT-1, enriched with 4-nitrotoluene as its sole source of nitrogen, was able to metabolize 2,4,6-trinitrotoluene under aerobic conditions. The dark red-brown metabolite, which accumulated in the culture fluid, was identified as a hydride-Meisenheimer complex by comparison with an authentic synthetic sample.
