Thermoelectric Properties of Thin Films from Sorted Single-Walled Carbon Nanotubes.

Single-walled carbon nanotubes (SWCNTs) remain one of the most promising materials of our times. One of the goals is to implement semiconducting and metallic SWCNTs in photonics and microelectronics, respectively. In this work, we demonstrated how such materials could be obtained from the parent material by using the aqueous two-phase extraction method (ATPE) at a large scale.

Study of Anti-oxidant, Anti-inflammatory, Genotoxicity, and Antimicrobial Activities and Analysis of Different Constituents found in Rhizome Essential Oil of Roxb., Collected from North East India.

Background: This investigation was designed to evaluate the chemical composition, antioxidant, anti-inflammatory, genotoxicity, and antimicrobial activities of Curcuma caesia Roxb rhizome essential oil.

Methods: Gas Chromatography/Mass Spectroscopy (GC/MS) analysis was performed to determine the chemical composition, standard antioxidative test DPPH assay, reducing power assay, in vitro antiinflammatory activity (egg albumin denaturation, protease inhibitory assay) by using standard methods. Similarly, antimicrobial activity was tested using the disc diffusion method, minimum inhibitory concentration ability (MIC); while to test genotoxicity, Allium cepa assay was used.
