“…[17][18][19] Sorbent-packed NTD is a traditional NTD mode. [20][21][22] Until now, several sorbents such as polydimethylsiloxane (PDMS), divinylbenzene (DVB), Carboxen 1000, Carbopack X, Tenax and Porapak Q are conventionally used for NTD. 11 For example, needle packed with activated-carbon-based sorbents was used for the analysis of very volatile organic compounds 23 and needle packed with Tenax TA and Carboxen 1000 particles was used for analysis of priority volatile organic compounds.…”

“…In recent years, many different techniques have been developed and successfully used to extract and detect VOCs, such as SPME techniques [4][5][6][7], sorbent traps [8][9][10], needletrap extraction (NTE) technology [11][12][13][14][15], and so on. In this field, NTE technology, which is a simple and cost-effective extraction process using solvent-free extraction and thermal desorption for the determination of VOCs, was recently developed [16].…”

In this study, a needle-trap device with fibers coated with a molecularly imprinted polymer was developed for separation. A number of heat-resistant Zylon filaments were longitudinally packed into a glass capillary, followed by coating with a molecularly imprinted polymer. Then, the molecularly imprinted polymer coating was copolymerized and anchored onto the surface of the fibers. The bundle of synthetic fibers coated with the molecularly imprinted polymer was packed into a 21G stainless-steel needle and served as an extraction medium. The coated-fiber needle extraction device was used to extract volatile organic compounds from paints and gasoline effectively. Subsequently, the extracted volatile organic compounds were analyzed by gas chromatography. Calibration curves of gaseous benzene, toluene, ethylbenzene, and o-xylene in the concentration range of 1-250 μg/L were obtained to evaluate the method, acceptable linearity was attended with correlation coefficients above 0.998. The limit of detection of benzene, toluene, ethylbenzene, and o-xylene was 11-20 ng/L using the coated-fiber needle-trap device. The relative standard deviation of needle-to-needle repeatability was less than 8% with an extraction time of 20 min. The loss rates after storage for 3 and 7 days at room temperature were less than 30%.

“…Graphene oxide shows antibacterial activity against a variety of microorganisms such as Pseudomonas aeruginosa [17], Staphylococcus aureus, Escherichia coli [18], P. syringae and X. campestris [19]. It also helps in the detection and removal of methylene blue and lead from waste water [20], [21].Graphene oxide also removes atmospheric air pollutants such as perchloroethylene normally present in air of dry cleaning industries [22].…”

Supramolecular self-assembly of nanostructures is widely pursued in different industrial and biological fields for many nano-materials including grapheme oxide (GO). In the present study, we synthesized using chemical method and characterized the self-assembled nanostructures of GO using UV-Vis spectroscopy, Fluorescence spectroscopy, Field emission Scanning electron microscopy and Dynamic light scattering particle size analysis. It was observed that the synthesized self-assembled GO nanostructures product showed the floral patterns. Such patterns were developed due to self-aggregation by nano-sized GO sheets. However, when the individual particle size distribution was observed, it was found to have a size distribution in the range of 50 to 250 nm.
