A series of monoazo disperse dyes based on naphthalimide was synthesized using N-alkylcarboxylic acid-1,8-naphthalimide as diazo component and N,N-diethylaniline derivatives as a coupling components. 4-amino-N-ethanoic (propanoic) acid-1,8-naphthalimide was synthesized from 4-nitro-1,8-naphthalic anhydride by imidation and subsequent reduction reactions. These compounds were diazotized and furt...

A series of sorbents containing various amounts of borate groups were prepared by chemical immobilization ofP-aminoethylphenylboric acid on a copolymer- treated organosilane spacer glass plates. It was found thatbaker's yeast cells selectively adhered to these supports. Yeast cells stained with procion red HE-3B formeddenser and more stable layer on the copolymer-grafted supports compared onto ...

Humic acid is used as an inexpensive starting material to prepare a strong adsorbent for the removal of Congo red from water.

in order to study the effects of cppu and ga3 on fruit quality and quantity of sultanina grapes, a factorial experiment in a randomized complete block design was implemented in a commercial vineyard near bonab city (west azerbaijan province). the spraying was done at fruit set stage using cppu and gibberellic acid. according to the results, it was found that these plant growth regulators had a ...

Preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of Nile red-loaded solid lipid nanoparticles. Nanoparticles (NPs) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. To solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

Mycoplasma colonies and Mycoplasma cells in preparations from infected milk and lymph nodes were observed for their fluorescent qualities after treatment with acridine orange. Mycoplasma colonies fluoresced brilliant red or red-orange. When treated after exposure to ribonuclease, the colonies fluoresced lime-green. There was no fluorescence when both ribonucleic acid and deoxyribonucleic acid w...

L. amylophilus GV6 was studied for production of L(+) lactic acid in single step fermentation using starchy substrates. Seven types of inexpensive organic nitrogen supplements (flour of pigeon pea, red lentil gram, black gram, bengal gram, green gram, soya bean and baker’s yeast) were evaluated for their potential to replace more expensive commercial nitrogen sources, peptone and yeast extract....

in this work, we report, optical properties of cd1-xsnxte quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (tga) as a modifier agent. the optical characterization of the samples was performed through absorption (uv) and photoluminescence spectra (pl). a red shift absorption and fluorescent emission peaks was observed which can be related to the increase of nano...
