Producing items that are of both high quality and long lasting is a difficult task for companies right now. There huge need wide range engineering materials in today’s technologically advanced globe. The strength qualities the material determine amount may be used. Due to its excellent mechanical low density, aluminum-7075 alloy mostly employed transportation applications such as aerospace, mar...

developing reliable and eco-friendly processes for the synthesis of metallic nanoparticles is an essential step in the field of application of nanotechnology .using natural factories such as biological systems is a way of developing such processes. nowadays, the synthesis of silver nanoparticles is very common due to its numerous applications in different fields. the synthesis of these nanopart...

Capping silver nanoparticles with LL37 peptide eradicates the antiproliferative effect of silver on primary skin cells, but retains the bactericidal properties of silver nanoparticles with activities comparable to silver nitrate or silver sulfadiazine. In addition, LL37 capped silver nanoparticles have anti-biofilm formation activity.

The present study was carried out to examine possible differential silver distribution among several tissues of three marine invertebrate species: the shrimp Penaeus duorarum, the sea hare Aplysia californica, and the sea urchin Diadema antillarum. Animals were exposed to sub-lethal concentrations of silver (1 or 10 microg/L) in seawater for 48 h. In gill-breathing species (shrimp and sea hare)...

Silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. A simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  The present study aimed at the comparative study of silver nanopartic...

In the present study, semi-purified laccase from Trametes versicolor was applied for the synthesis of silver nanoparticles, and the properties of the produced nanoparticles were characterized. All of the analyses of the spectra indicated silver nanoparticle formation. A complete characterization of the silver nanoparticles showed that a complex of silver nanoparticles and silver ions was produc...

Silver, both in the nano as well as in other forms, is used in many applications including antimicrobial textiles. Washing of such textiles has already been identified as an important process that results in the release of silver into wastewater. This study thus investigated the release of silver from eight different commercially available silver-textiles during a washing and rinsing cycle. The...

Objective To compare the clinical efficacy and safety of oil gauze silver dressing and silver ions dressing on diabetic ulcers in elderly outpatients. Methods Twenty-two patients with Type-2 diabetic foot ulcers were included in the study conducted at Yantai Yuhuangding Hospital between April 2013 and April 2014. At the time of enrolment they were divided into the silver ions and oil gauze si...

In the present work, a mesoporous multiphase amorphous crystal nanopowder Bi2O3 with specific surface area of up to 23 m2/g was produced by pulsed electron beam evaporation in vacuum. Influence thermal annealing (200-500 °C) powders air is investigated. The formation droplets size 3-5 nm on all large nanoparticles constituting framework 3D agglomerates found due extrusion liquid bismuth from vo...
