Effect of carbon nanotube wastes on soil

Carbon nanotubes Various forms of nanotubes are added to a variety of products during their manufacture and biomedical applications to increase the strength of the materials without adding much weight. Nanotube manufacturing waste products and bio-solids that result from such applications as in water purification may find their way into wastewater treatment plants. These bio-solids cannot be released into water bodies and so they are often discarded by spreading on land. Similarly both carbon nanotubes and functionalized carbon nanotubes (with modifications to create chemical or biological changes to the nanotubes) are often used in medicines. Majority of the wastes emanating from these sources may also be disposed into soil. Data on the effects of the release of these nano materials on environment, particularly in high or low organic soils remains sparse. Effect on soil Results indicate that repeated applications of as-produced SWNTs can affect microbial community structures and induc

Nanoparticle disposal and exposure

Environmental pollution by carbon particles emitted by car exhaust, smoking and long term inhalation of dust of various origins cause chronic inflammation of the lungs and has link to rheumatoid arthritis. Similarly nanomaterials are reported to have health and safety implications for the manufacture, use and ultimate disposal of nanotechnology products and materials. Exposure to nanoparticles is found to have a serious impact on health and link to rheumatoid arthritis and the development of other serious autoimmune diseases. Nanotechnology products which if not handled appropriately may contribute to the generation of airborne pollutants causing risks to health. Research Researchers at Trinity College Dublin's School of Medicine have investigated whether there is a common underlying mechanism contributing to the development of autoimmune diseases in human cells due to the exposure nanoparticles. The researchers applied nanomaterials such as ultra fine carbon black, carbon nanotube

Is nanotechnology data stolen?

Jianyu Huang working  at Sandia National Labs as a staff Scientist. He is working on materials physics, electron microscopy, battery, nanomechanics of nanotechnology.Since 2007 his publications have been quoted by more than 3800 times. He was arrested recently because he allegedly stole laboratory research and shared it with China.He is being accused of stealing research belonging to the U.S. that he claimed was his own original research. He allegedly shared with several Chinese universities and went online to share the data with the country’s state-run schools including Peking University and the Harbin Institute of Technology. But Sandia National Labs says that he did not have access to classified national security information. Huang was fired in April for removing a company-owned laptop from the facility. Sandia, a subsidiary of Lockheed Martin Corporation is known for its nuclear research, as well as the disposal of the U.S. nuclear weapons program’s hazardous waste and focusing on
