Nanoscience : The Role of “ Making ” New Forms of Matter
نویسنده
چکیده
“Nano” of course means “billionth of”. Nanoscience has been defined as the science of matter with characteristic lengths ranging from 1nm to 100nm. In practice, nanoscience is a collection of portions of traditional disciplines. That is, it is a union of subdisciplines. Here are just a few of the component subdisciplines: materials chemistry, polymer science, colloid chemistry, crystal growth, surface science, solid-state physics, microelectronics, structural biology, ...

Challenges of an exhibit on nanoscience and nanotechnology
This article presents some of the challenges faced in developing an interactive exhibit on nanoscience and nanotechnology in Brazil. Presenting a scientific-technological area which is still in formation and which is little known by the population leads to a (re)consideration of the role of museums and science centers in the conformation and consolidation of scientific practice itself. Museogra...
متن کاملRole of organic matter, clay, and iron contents in the sorption of oxytetracycline on river sediments
Background: Oxytetracycline (OTC) is a widely-used antibiotic; metabolism studies indicate only partial assimilation of it inside the body. Traditional wastewater treatment plants cannot remove OTC, and this results in the release of considerable amounts of the drug into aquatic environments. There is much concern over the role of residual antibiotics in the development of new generations of ba...
متن کاملThe Relationship Between the Chemical Forms of Copper in the Soil Solid Phase Affected by Crop Residues With Phytoavailability of Copper in Soil
Returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. In addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

متن کاملA New and Efficient Method for the Adsorption and Separation of Arsenic Metal Ion from Mining Waste Waters of Zarshouran Gold Mine by Magnetic Solid-Phase Extraction with Modified Magnetic Nanoparticles
Widespread arsenic contamination of mining wastewater of Zarshouran (West Azerbaijan province) has led to a massive epidemic of arsenic poisoning in the whole of surrounding areas. It is estimated that approximately all agriculture fields are being irrigated with the water that its arsenic concentrations elevated above the World Health Organization’s standard of 10 parts per billion. A novel ad...
