The development of the eco friendly procedures makes nanoparticles as the rapidly growing field of nanotechnology. Amongst, the silver nanoparticles have become prominent in the field of medicine to their peculiar antimicrobial properties. In the present study we suggest an eco friendly procedure of extracellular synthesis of silver nanoparticles with an average sizes of 5-50nm using an Act...

Heterogeneous reagent systems have many advantages such as simple experimental procedures, mild reaction conditions and minimization of chemical wastes as compared to the liquid phase counterparts. Al(HSO4)3 as an heterogeneous, efficient, readily available, and cheap catalyst was synthesized and applied for the synthesis of 1,3-benzo[d]thiazole derivatives by con...

2-Amino-3-functionally substituted thiophene de­ rivatives are important intermediates to the phar­ maceutically important thieno[2,3-d]pyrimidines [2]. These thiophene derivatives were available from the procedures published by K. Gewald [3, 4] via either the reaction of a-methylene ketones with active methylene nitriles in presence of elementary sulphur of from a-mercaptoketones and active me...

A highly efficient solid-phase synthesis method for the preparation of fluorogenic protease substrates based upon the bifunctional leaving group 7-amino-4-carbamoylmethylcoumarin (ACC) is reported. Methods for the large-scale preparation of the novel fluorogenic leaving-group ACC are provided (Scheme 1). Detailed procedures are also provided for loading a diverse set of amino acids to support-b...

Reliable stabilization and regulation of two-channel decentralizedmulti-inputmulti-output (MIMO) control systems is considered. The system has integral-action due to using proportional+ integral+ derivative (PID) controllers. Closed-loop stability and asymptotic tracking of step-input references are achieved at each output channel when all controllers are operational. Stability is maintained wh...

Aminothiazoles and their derivatives are of immense biological importance and have been consistently synthesized via various methods. However, the synthesis of aminothiazole derivatives has some problems such as poor yields, difficult isolation procedures, use of expensive catalysts etc. Recently, polymer or solid-supported synthetic protocols have attracted the attention from the research comm...

Due to their unique chemical and physical properties, carbon-based NanoMaterials (C-NMs) are largely exploited in biomedicine, i.e., cell and tissue imaging, drug delivery and tissue engineering scaffold, even if reports regarding their toxicity are still conflicting. In fact, biological effects strictly depend on the dynamic physicochemical characteristics of CNMs, which in turn are strongly i...

   The use of plant extract in the biosynthesis of nanoparticles (NPs) can be an eco-friendly approach and have been suggested as a possible alternative to classic methods namely physical and chemical procedures. This study was designed to examine the structural chemistry of silver nanoparticles (AgNPs) using both conventional heating and microwave irradiation methods.To o...
