Background Amongst the methods that remove heavy metals from environment, biosorption approaches have received increased attention because of their environmentally friendly and cost-effective feature, as well as their superior performances. Methods In the present study, we investigated the ability of a surface-engineered Escherichia coli, carrying the cyanobacterial metallothionein on the cel...

The identification of different grapevine varieties, currently attended using visual ampelometry, DNA analysis and very recently, by hyperspectral analysis under laboratory conditions, is an issue of great importance in the wine industry. This work presents support vector machine and artificial neural network's modelling for grapevine varietal classification from in-field leaf spectroscopy. Mod...


 Gmelina arborea Roxb. (Family Verbenaceae) leaves have long been used in traditional medicine to cure a variety of medical conditions. The purpose this study is examine the methanol, hydro alcohol, aqueous, hexane, ethyl acetate, extracts through FTIR spectroscopy method. (Fourier transform infrared spectroscopy) quick and nondestructive analysis technique. was utilised on spectrophotome...

HE PRINCIPAL SUBJECT MATTER of this paper is the description of a thod of obtaining a calibration curve relating apparent absorbancy 81) and concentration (x). It is frequently observed that the orbancy index decreases with increasing concentration in cases in ich one would expect Beer’s law, A = log(10/I) = KX, to hold. For ample, with our instrument, the absorbancy index at 273.5 m of a lutio...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...
