metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using mie theory. however a major disadvantage of metallic spherical nanoparticles is ...

Contamination of water resources with pesticides residues becomes a pressing problem in Gaza due to the frequent application of pesticides in the intensive agricultural system. This study tests the potential of using organo-bentonite as a porous material to remove bromoxynil residues from contaminated water. Bentonite surfaces were activated for removal of bromoxynil residues from water by simp...

background: based on the economical and environmental concepts, the main purpose of the industrial waste management is reducing the production of these materials which is accessible by developing strategies of reuse, waste recycle and upgrading the technologies. accurate investigation of the quality and quantity of the industrial waste is the basis of the industrial waste correct management. th...

In this research, the nickel oxide was dissolved in cryolite at temperatures of 880, 940 and 1000°C. In order to reduce the nickel oxide, aluminum was added to the salt. Simultaneously the nickel oxide was reduced and Al3Ni2 intermetallic compound was formed. In the duration intervals of 2.5-40 minutes samples of the salt and metallic phases were taken. The variation of the nickel content in me...

Hydroxyapatite coatings have been used on metallic substrates in a variety of applications, including modifying the surface of human implants, bone osseointegration and biological fixation. In this paper, the effects of various kinds of metallic substrate on clinical and pathological results of in vivo tests are presented. Four kinds of endodontic implants i.e, stainless steel, cobalt base all...

conclusions anesthetic and surgical management was difficult due to the inability to position in supine and rapidly progressing hemorrhagic shock. surgical management for extraction of this iron bar and intensive monitoring and resuscitation resulted in an uneventful successful outcome. introduction penetrating thoracoabdominal injuries are potentially life threatening due to the associated hem...

Metallic glasses are kinetically metastable materials. Metallic glass is defined as “A liquid, which has been cooled into a state of rigidity without crystallizing”. Properties of metallic glasses differ form non metallic glasses. Ordinary glasses are made up of silica while metallic glasses are made of alloy metals. Ordinary glasses are transparent whereas metallic glasses are opaque. In ordin...

Coastal aquatic ecosystems are environments increasingly affected by human activities due to urban discharges and their use as dumps. The objective of this study is determine the profiles metallic elements concentration (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Pb) Cotonou channel sediments evaluate quality. For this, surface (0-5cm) were sampled at 13 sites along channel. Thus,Geoaccumulation I...
