NANO Magazine - Issue 10
NANO Magazine, Feb 2009, Pages: 44
In this issue, NANOexamines new technologies that are providing solutions to the problem of green energy production and changing the way we think about energy usage.
Green Energy- Revolution Required to Power the Planet
The search is on for alternative energy sources that will diminish the current demand for fossil fuels and thereby remove the release of carbon emissions into the atmosphere. Solar cells to harness energy from the sun and fuel cells that generate electricity with hydrogen power are two of the most promising examples.
Can Nanotechnology Save The Planet? Only if governments get serious
The role of government is highlighted. Lack of leadership verging on cowardice describes the failure of ostrichlike governments to act in cutting CO2 emissions and Saxl calls for urgent action now to curb the excesses of today to prevent a catastrophe tomorrow. She examines the need for novel technologies and describes some nanotechnology solutions that are already being commercialised or near to market.
Iron Works- Using Scrap metal to clean water?
We explore the use of iron shavings and nanosized iron particles in water treatment techniques and specifically a major study conducted in China over six years to enhance the treatment of industrial waste water.
A Breath of Fresh Air
The article also examines nano-based techniques, in this case for removing pollution, including emissions ranging from greenhouse gases to tobacco smoke, from the air. Here, molecular sieves are investigated for their potential to filter contaminants from the atmosphere in work being conducted at Stony Brook in New York.
Chameleon Construction
Researchers in Greece have been developing a novel solution to the high air-conditioning costs needed to cool city buildings during the hot summer months. Clever nano-based paints that change colour depending on the temperature have been shown to be effective at keeping the building cool in summer and warm in winter. Described in the article on Chameleon Construction, such paints could be an easy solution to treating buildings already known to be high energy consumers.
Other Topics
Nano's Champion.
Ottilia Saxl speaks with Nano-pioneer Dr. james Murday about his inspiration to bring nano to the forefront of U.S. Scientific research.
Nano USA
The USA is the profiled country in this issue. The US likes to lead by example and nanotechnology is no exception. For the past decade, nanotechnology has been an important area of research for the country. The National Nanotechnology Initiative drives the research and a $1.5 billion budget has been allocated to nanotechnology research in 2009. We take a look at what is being done with such a mammoth investment.
Communicating Nanotechnology
After President Obama's address citing the need to “again put science at the top of our agenda” Tina Hoermann takes a look at the future for Nanotechnology communications at what could be described as a definate cross-roads in its development. From the future of the GM debate to the use of youtube as a forum for scientific networking, we look at what nano can do to ensure it takes the brightest path.
Regular features
We tale a look at new developments in Nanosuch as the gold-based drug delivery system which can deliver multiple medicines in a controlled fashion, the nanodiamonds that have shone a new light on cosmic events, an exciting development for optical circuitry, the new warning by researchers who say that there must be distinction between toxicology and nanotoxicology, carbon nanotubes that can help by-pass faulty brain wiring, the need for the US to understand more about the risks associated with nanomaterials, and the creation of nano-forklifts.
In our nanomedicinefeature, we delve into the difficulties of getting the right quantity of a drug to its target site in the body, as well as the novel methods being developed to offer more patient-friendly solutions.
