Cellulose, chitin and chitosan are the most abundant biopolymer on earth and constitute an important class of biodegradable materials. The decomposition of three major biopolymers viz. chitin, chitosan and cellulose are studied using simultaneous thermal analysis i.e. thermogravimetry/differential thermal analyzer (TG/DTA). Thermal analysis is performed(More)
BACKGROUND Thiazolidine-2, 4-diones (TZDs) have become a pharmacologically important class of heterocyclic compounds since their introduction in the form of glitazones into the clinical use for the treatment of type 2 diabetes. TZDs lower the plasma glucose levels by acting as ligands for gamma peroxisome proliferators-activated receptors. In addition, this(More)
A series of nine new compounds of 5-((3-(aryl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-phenylthiazolidine-2,4-diones was synthesized by Knoevenagel condensation of various 3-(aryl)-1-phenyl-1H-pyrazole-4-carbaldehydes with 3-phenylthiazolidine-2,4-dione in ethanol in the presence of piperidine as a catalyst. The reaction afforded the desired products in good(More)
In the present study, poplar (Populus) wood is coated with intumescent formulation (ammonium polyphosphate/melamine/pentaerythritol), using acrylic resin as binder. Samples have also been prepared by adding fly ash (FA) in intumescent formulation at different loading levels. Thermal stability of composites has been studied with thermogravimetry, derivative(More)
Two series of compounds namely, dihydroindeno and indeno [1,2-e] [1,2,4]triazolo [3,4-b] [1,3,4]thiadizines (9a-l & 11a-l) were synthesized by cyclocondensation between α-bromoindanones (7a-b) or/and α,α-dibromoindanones (8a-b) and various 3-alkyl/aryl-4-amino-5-mercapto-1,2,4-s-triazoles (3a-f) in methanol with an aim to explore their effect on in vitro(More)
The present paper depicts about the synthesis of cellulose ethyl ammonium thiophosphate (CEASP) and its metal complexes with Cd, Mo and Ce. CEASP and its metal complexes have been characterized by infrared (IR), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDXS) studies. The surface morphology of samples has been premeditated by means(More)
A series of 5-((3-aryl-1-phenyl-1H-pyrazol-4-yl)methylene)thiazolidine-2,4-diones was synthesized by Knoevenagel condensation of various 3-aryl-1-phenyl-1H-pyrazole-4-carbaldehydes (1a–h) with thiazolidine-2,4-dione (2) in ethanol in the presence of piperidine. All compounds were screened for their in vitro antibacterial (Staphylococcus aureus, Bacillus(More)
