The extensive use of nanoparticles in a variety of applications has raised great concerns regarding theirbiological effects and environmental fate. Silver nanoparticle, often referred to as nanosilver (n-Ag), maycause health problems because of its wide and ever growing use in many applications. n-Ag is used intreatments of wounds, disinfection of water and/or air and coatings textiles. n-Ag is...

Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processi...

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...

abstract   introduction: diabetes mellitus accompanies with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. considering the beneficial antidiabetic potential of apium graveolens (ag ), this research study was conducted to evaluate the effect of chronic i.p. administration of ag on learning and memory in diabetic rats using passive avoidance ...

Poly (N-isopropylacrylamide-acrylic acid) [p(NIPAM-AAc)] microgel was successfully fabricated using the precipitation polymerization method. Silver (Ag) nanoparticles and graphene oxide (G) were used to fabricate following hybrid microgels: Ag-p(NIPAM-AAc) (Ag-HMG), Ag-G-p(NIPAM-AAc) (Ag-G-HMG), G-p(NIPAM-AAc) (G-HMG). Ag-HMG, Ag-G-HMG, G-HMG characterized a Zetasizer UV-Vis spectroscopy. The r...

Management of workkow processes is more than just enactment of process activities according to business rules. Time management func-tionality should be provided to control the lifecycle of processes. Time management should address planning of workkow executions in time, provide various estimates about activity execution durations, avoid violations of deadlines assigned to activities and the ent...
