The carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through Bulk Liquid Membrane (BLM) and Supported Liquid Membrane (SLM) systems. The various membrane supports used are viz. PTFE, cellulose nitrate, and dialysis membrane and onion membrane. The amount of Li+ transported depends upon the stru...

A Dionex ICS-2000 ion chromatograph was used to detect the c...

High nitrate concentrations in salads and vegetables have attracted increased attention. It is well know that nitrate can cause serious health problems to humans such as methemoglobinemia of infants 111. Under certain conditions, specially in the human body carcinogenic nitrosamines can be formed [2]. However, nitrate content of different types of vegetables fluctuates substantially with variet...

Nitrate transporters are an important component of plant growth and development. Chrysanthemum morifolium is an important ornamental species, for which a sufficient supply of nitrogenous fertilizer is required to maintain economic yields. In this study, the full-length cDNA of the nitrate transporter genes CmNRT2 and CmNAR2 were isolated. CmNRT2 transcript accumulation was inducible by both nit...

Explosives detection is a necessary and wide spread field of research. From large shipping containers to airline luggage, numerous items are tested for explosives every day. In the area of trace explosives detection, ion mobility spectrometry (IMS) is the technique employed most often because it is a quick, simple, and accurate way to test many items in a short amount of time. Detection by IMS ...

I report a facile wet-chemical method for the synthesis of one-dimensional copper hydroxide nitrate nanostructures in 2-propanol under solvothermal conditions. Single-crystalline nearly monodispersed copper hydroxide nitrate nanorods and nanobelts with selected breadths in the range of 100 nm to 1 μm have been successfully prepared by a solvothermal method through controlling the experimental p...

Positively-charged crystalline zinc hydroxide nanostrands with a diameter of 2 nm and a length of a few micrometres rapidly grew in dilute aqueous solution of zinc nitrate and aminoethanol. The nanostrands were composed of hexagonal clusters of [Zn(61)(OH)(116)(H(2)O)(n)](6+).
