Novel ionic water-soluble tetrabenzoporphyrins have been successfully synthesized via a cascade reaction based on the Heck reaction. The UV-Vis spectra of these porphyrins displayed red-shifted and broadened Soret bands, and significantly enhanced Q bands. These porphyrins are highly water soluble.

the present study aimed to evaluate the effect of dipping time and temperature of hot water and type of packaging on qualitative traits of orlando tangelo variety of tangerine. this study was conducted as a factorial experiment in a completely randomized design with three repeats. the treatments consisted of dipping in hot water at seven water levels at 53°c and 58°c each for 1, 2 and 4 minutes...

drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of iran. detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. six wild populations of anthemis tinctoria, were assigned to four drought treatments, i.e. well-watered ...

Chlorine in char derived from municipal solid waste (MSW) was characterized and quantified based on its water solubility: easily water-soluble, hardly water-soluble, and non-water-soluble chlorine. For that, a four-cycle process of water-washing, heating or carbonation were carried out. In order to confirm the characteristics of non-water-soluble chlorine, additional thermal treatment and an al...

Objective N-octyl-N '- (2-carboxycyclohexanecarbonyl) -chitosan derivative (OCCC) was successfully synthesized. The analysis of the chitosan by infrared spectroscopy, nuclear magnetic resonance spectroscopy and like used to verify whether synthesis successful. To construct characterize nanoparticles with bovine serum albumin as model drug. transmission electron microscopy (TEM), encapsulation e...

batiaghata upazila, khulna district in south-west coastal region of bangladesh is the mostly saline affected area, where agriculture activities are mainly dependent on rainfall. 23 water samples from surface water and shallow tube well (stw) were collected in the monsoon season and analyzed for physico-chemical properties to classify them according to salinity hazard. electrical conductivity (e...
