NANOTECHNOLOGY
Nanotechnology is the study and use of structures between 1 nanometer and 100 nanometers in size. Website discussing the latest uses of nanotechnology in electronics, medicine, energy, consumer products andall other fields.
NANOTECHNOLOGY THERAPY TECHNIQUES A survey of nanotechnology therapy techniques: Researchers at the University of Wisconsin have demonstrated a bandage that applies electrical pulses to a wound using electricity produced by nanogenerators worn by the patient. Researchers have developed "nanosponges" that absorb toxins and remove them from the bloodstream. ENVIRONMENTAL NANOTECHNOLOGY Environmental Nanotechnology . Nanotechnology is being used in several applications to improve the environment. This includes cleaning up existing pollution, improving manufacturing methods to reduce the generation of new pollution, making alternative energy sources more cost effective and may be useful to achieve some of the goals the Biden adminstration is setting to help the environment. FUEL - NANOTECHNOLOGY - UNDERSTANDINGNANO Nanotechnology can address the shortage of fossil fuels such as diesel and gasoline by: Making the production of fuels from low grade raw materials economical. Increasing the mileage of engines. Making the production of fuels from normal raw materials more efficient. Nanotechnology can do all this by increasing the effectiveness ofcatalysts.
NANOTECHNOLOGY AND ENERGY The Application of Nanotechnology to Energy Production. Here are some interesting ways that are being explored using nanotechnology to produce more efficient and cost-effective energy: Generating steam from sunlight. Researchers have demonstrated that sunlight, concentrated on nanoparticles, can produce steam with high energyefficiency.
REGULATION OF NANOTECHNOLOGY MATERIALS The lead in your pencil is a larger scale or bulk version of carbon that has different properties than carbon nanotubes and buckballs, even though all three share the same chemical composition. MOLECULAR MANUFACTURING The Foresight Institute has developed a roadmap to guide researchers working toward molecular manufacturing.. The Nanofactory Collaboration's long term goal is to design, and ultimately to build, a working nanofactory. Their initial goal is the experimental demonstration of controlled diamond mechanosysthesis, i.e. using a mechanical tooltip to place individual carbon atoms in a structure. AIR POLLUTION AND NANOTECHNOLOGY Air Pollution: Nanotechnology Applications under Development.

WELCOME TO UNDERSTANDINGNANO Focused around the uses of nanotechnology, UnderstandingNano offers information about companies and research labs involved in nanotechnology, as well as descriptions of nanomaterials and lesson plans for teachers and students. You can find information on nanotechnology topics by using the navigation bar above or through the Quick Links on the right side of many pages. HOT TOPIC: IMPROVING BATTERY CAPACITY USING NANOTECHNOLOGY Improving battery capacity can help our energy efforts from more efficient electric grids to building better electric cars. One possible way to improve li-ion battery capacity is to use silicon anodes. “Putting silicon into batteries can produce a huge increase in capacity—10 times greater,” said Dr. Philip Bradford, Assistant Professor of textile engineering, chemistry, and science at North Carolina State. “But adding silicon can also create ten times the problems.” That’s because silicon swells when a lithium-ion battery discharges energy. In a process referred to as pulverization, silicon breaks off from electrodes as a battery cycles. These pieces of silicon can make a battery unstable. Researchers have been looking to nanotechnology to solve this challenge. A young company, TruSpin , is reporting the development of a silicon nanofiber anode that may help significantly increase the capacity of li-ion batteries. According to TruSpin in an article that appeared in the Alabama News Center, "The total electrification of America is the future. A true breakthrough in battery technology willenable this."
