polyurethane Silver fibers prepared by infiltration and reduction of Silver Nitrate
Materials Letters, 2006Co-Authors: Jung Hyun SoAbstract:Abstract Silver-incorporating polyurethane fibers were prepared by infiltration of Silver Nitrate on electrospun polyurethane fibers and reduction with sodium borohydride. They were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy-dispersive X-ray system. The Ag nanoparticles prepared by reduction of Silver Nitrate showed nano-sized crystals of 4–10 nm in diameter. However, larger aggregated Ag particles of 50–200 nm were also found to be dispersed in the polyurethane matrix when Ag particles were formed in electrospun fibers by the infiltration–reduction process of Silver Nitrate. As a result, infiltration method of Silver Nitrate into the electrospun fibers was significantly effective to produce Silver-incorporating fibers due to a high specific surface area of fibers.

In vitro modification of sex expression in mulberry (Morus alba) by ethrel and Silver Nitrate
Plant Cell Tissue and Organ Culture, 2004Co-Authors: T. Dennis ThomasAbstract:Mulberry (Morus alba L.) is a dioecious plant. In vitro sex modification in mulberry by using two chemicals, viz., ethrel and Silver Nitrate, is described. 2-Chloroethylphosphonic acid (ethrel) and Silver Nitrate were filter sterilized and added to Murashige and Skoog (1962) medium supplemented with 5 {muM} 6-benzyl amino purine ({BA).} Ethrel applied at different concentrations produced female, male and mixed inflorescences in male mulberry nodal cuttings. Maximum 13.6% female inflorescences were observed on media containing 2000 mug l(-1) ethrel. The induction of male, female and mixed inflorescences was observed in female plants after applying Silver Nitrate to the culture medium. The number of male inflorescences increased with the Silver Nitrate concentration to a maximum of 22.4% induction on 2500 mug l(-1). Bisexual flowers were also observed along with male and female flowers in Silver Nitrate treated plants.

effect of nano Silver and Silver Nitrate on seed yield of borage
Journal of Medicinal Plants Research, 2011Co-Authors: A. Sorooshzadeh, H Rezazadehs, H. A. NaghdibadiAbstract:Borage plant (Borago officinalis L.) is an herbaceous annual plant. It was used as a medicinal plant since ancient times. Seed oil of this plant has been used to treat many skin disorders. It is the richest plant source of gamma-linoleic acid (GLA). However, seed production of borage is limited by flower and seed abscission. Ethylene is responsible for plant organs abscission which may be inhibited by Silver ion (Ag+). Therefore, this experiment was designed to study the effect of nano Silver and Silver Nitrate on abscission and yield of seed in borage. The study was carried out in a randomized block design with three replications. Four levels of either Silver Nitrate (0, 100, 200 and 300 ppm) or nano Silver (0, 20, 40, and 60 ppm) were sprayed on borage plant at seed growth stage. The results showed that there was no significant difference between 100 ppm of Silver Nitrate and 60 ppm concentration of nano Silver on the shoot Silver concentration. However, increasing the concentration of Silver Nitrate from 100 ppm to 300 ppm caused a decrease in seed yield. On contrast, a raise in the concentration of nano Silver from 20 ppm to 60 ppm has led to an improvement in the seed yield. Additionally, the lowest amount of seed yield was found with control plants. Finally, with increasing level of Silver Nitrate, the polyphenols compounds content were raised, but the enhancing level of nano Silver resulting in the reduction of these components. In conclusion, nano Silver can be used instead of other compounds of Silver. Key words: Borage, nano-Silver, Silver Nitrate.

Silver Nitrate burns following treatment for umbilical granuloma
Pediatric Emergency Care, 1992Co-Authors: James M. Chamberlain, Richard L. Gorman, Grace M. YoungAbstract:: Three infants treated for umbilical granuloma with Silver Nitrate suffered chemical burns to the periumbilical area which prompted visits to the emergency department. Treatment was conservative, and the outcome was good in all cases. We recommend caution when applying Silver Nitrate to the umbilicus, careful drying of the umbilical exudate to prevent spillage, and discussion with parents that burns may occur but apparently are not serious. The possibility of secondary infection is discussed.
