In this research, synthesis and characterization of silver/alumina composite powders was investigated. This kind of metal/ceramic composite powders is used for fabrication of cutting tools inserts. The role of silver is toughening the final product. The powders were synthesized via co-precipitation method. The composition of the synthesized powders was Ag/80% wt 〖Al〗_2 O_3. Silver nitrate, alum...

plants are rich source of natural products used for centuries to cure various the plant-derived medicines are based upon the premise that they contain natural substances that can promote health and alleviate illness. silver nps represent material, which can be used as a potential antibacterial agent in medical applications and different commercial products due to its biological activity. recent...

Controllable silver nanoparticles were developed by a green approach using extracts of both leaves and bark of Limonia acidissima tree. Due to the presence of phytochemical compounds in L. acidissima leaves and bark; such as saponins, phenolic compounds, phytosterols, and quinines present in extracts act as reductants, hence the silver nanoparticles were easily produced under mild conditions. T...

A critical review of studies examining exposures to the various forms of silver was conducted to determine if some silver species are more toxic than others. The impetus behind conducting this review is that several occupational exposure limits and guidelines exist for silver, but the values for each depend on the form of silver as well as the individual agency making the recommendations. For i...

Iranian and Pakistani traditional physicians have derived the advantages of silver compounds by processing silver to a specific preparation called Kushta to treat skin cancers. This study investigated silver Kushtas in comparison with silver nanoparticles in the terms of morphology, silver content, and chemical composition. Materials and Methods: Iranian silver Kushta (IKAg) powder was produced...

Silver is a naturally occurring element. Similar to other metals, the ionized form of silver (Ag(+1)) has known antimicrobial properties. A number of wound dressings incorporating silver ion or silver compounds have recently been developed and marketed. In addition, the antimicrobial effects of silver are currently being promoted in consumer products such as clothing and household appliances. T...

In this experiment, green-synthesized silver and gold nanoparticles were produced rapidly by treating silver and gold ions with an extract of Memecylon umbellatum leaf. The reaction process was simple and easy to handle, and was monitored using ultraviolet-visible spectroscopy. The effect of the phytochemicals present in M. umbellatum, including saponins, phenolic compounds, phytosterols, and q...

Silver has a long and intriguing history as an antibiotic in human health care. It has been developed for use in water purification, wound care, bone prostheses, reconstructive orthopaedic surgery, cardiac devices, catheters and surgical appliances. Advancing biotechnology has enabled incorporation of ionizable silver into fabrics for clinical use to reduce the risk of nosocomial infections and...
