The health effects of nanoparticles (NPs) are raising considerable and growing concerns from the public and government around the world. Nano-metals are new forms of metal with special properties, but are characterized by having a particle size of less than 100 nm. Copper is an essential trace element and its deficiency leads to different diseases in humans. In gen...

This study is primarily focused toward measuring the particle size distribution and chemical analysis of particulate matter that originates from combustion sources typically found in Indian urban homes. Four such sources were selected: cigarette, incense stick, mosquito coil, and dhoop, the latter being actually a thick form of incense stick. Altogether, seven of the most popular brands availab...

objective(s): the development of reliable and ecofriendly process for the synthesis of nano-metals is an important aspect in the field of nanotechnology. nano-metals are a special group of materials with broad area of applications. materials and methods: in this study, extracellular synthesis of silver nanoparticles (snps) performed by use of the gram positive soil streptomycetes. streptomycete...

A metal-assisted microwave treatment that converting raw coal powders into nano-graphite is presented. Specifically, four major factors are identified for successful conversion: (1) high temperature; (2) reducing environment; (3) catalyst; and (4) radiation. it determined the combination of carbon sources (raw powders), temperature (microwave induced electric sparking), environment (the Ar/H2 m...

Montmorillonite has been widely used in remediation of toxic metals. However, for the safety soil ecosystem, impact this technology on microorganisms is still unclear. Here, influence nano-montmorillonite immobilization, accumulation cadmium, and microbial activity a soil–plant system was investigated. The results revealed that treatments reduced cadmium bioavailability uptake by oilseed rape. ...

Achieving strong repulsive Casimir forces through engineered coatings can pave the way for micro- and nano-electromechanical applications where adhesive currently cause reliability issues. Here, we exploit Lifshitz theory to identify requirements in gyrotropic media two limiting cases (ultra-strong gyroelectric non-gyroelectric). We show that origin of force with gyrotropy such as Weyl semi-met...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

Abstract Background Nano-particles of metals can be routinely synthesized. The cereal seeds treatment with the particles improve early growth and crop production. Moreover, is robust economical. Methods Metal (Fe 0 , Cu Co ), zinc oxide (ZnO) chitosan-stabilized silver nano-particles were synthesized applied to seeds. germination rate, plant development inhibition effects on pathogenic fungi qu...
