A Nano solution to the crisis in antibiotic resistance?
Supported by 193 nations, the United Nations in a General Assembly meeting in September 2016 declared antibiotic resistance to be "the greatest and most urgent global risk." Shu Lam, a PhD student from Malaysia in the Department of Chemical and Biomolecular Engineering at the University of Melbourne in Australia, has helped create antimicrobial agents from nanotechnology that appear able to fight back against SuperBugs and other antibiotic resistant germs that kill hundreds of thousands of people annually.

Nano brings advances in solar power
Researchers at the University of Texas are working to improve the efficiency of solar panels, which could lead to lower energy costs.
A team is replacing silicon slabs in solar panels with cadmium telluride ink, a new synthetic material made of crystals, because the material is smaller and the crystals absorb sunlight better. [More Info]
In Switzerland, nanomaterial called graphene can take one photon and make multiple electrons which have the potential of doubling existing conversion rates. Solar panels will get smaller, and areas that have marginal value for solar generation will get a second look as panels improve efficiency.
Also nano research is finding that silicon crystals known as quantum dots can increase the charge/discharge cycles of batteries, improve computer displays, and decrease power consumption. [More Info]

Research Progress on Environmental, Health, and Safety Aspects of Engineered Nanomaterials
THE NATIONAL ACADEMIES PRESS, 2013
"Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions."

The Swift Accumulation of Nanoparticles in Wetlands
SUMMARY from the Center for the Environmental Implications of NanoTechnology, Duke University:
A Duke University team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indirectly damage the aquatic food chain.
The results indicate little risk to humans ingesting the particles through drinking water, say scientists at Duke’s Center for the Environmental Implications of Nanotechnology (CEINT). But the researchers warn that, based on their previous research, the tendency for the nanotubes to accumulate in sediment could indirectly damage the aquatic food chain in the long term if the nanoparticles provide “Trojan horse” piggyback rides to other harmful molecules.
The results appear online in the journal Environmental Science: Nano (2014).

"The goal of the Registry is to archive a sufficiently large, accessible, and centralized body of integrated information to enable researchers in gaining knowledge from accumulated data. As computational tools and researchers interact with the information in the central data repository, knowledge will be extracted and used to guide new research and, ultimately, the safe use of nanomaterials."

The ETUI, nanotechnologies, and health in the workplace
The European Trade Union Institute (ETUI), a Brussels-based independent research and training center of the European Trade Union Confederation (ETUC), continues to demand more transparency and accountability over nanomaterials in the workplace. See the ETUI’s critique of the European Commission from October 2012:
[Go to Critique]
According to the summary of an ETUI Working Paper on nanotechnology from 2010, “Nanotechnologies may be an economic opportunity that the EU cannot ignore, but their unregulated development is causing growing concern among trade unions due to the health risks posed by certain types of nanomaterials.” [More]
Scientists fear that nanomaterials could harm soil fertility and food quality
Patricia Holden, an environmental microbiologist at the University of California Santa Barbara, indicates that nanomaterials such as nano-zinc oxide and nano-cerium oxide can build up in crops and may under certain conditions damage soil. Nevertheless, she cautions people not to be “be scared of our soybeans. There’s still a lot we don’t know.”

Deepwater Horizon, on fire after the explosion
Source: US Coast Guard
The explosion of Deepwater Horizon, one of BP's massive oil rigs situated about 40 miles from the Louisiana coast, has been unleashing, according to some estimates, 20,000-100,000 barrels of oil daily since it exploded on April 21, 2010.
new nanotechnology dispersant may be the key to cleaning up the spill but many scientists are skeptical about the environmental impact of introducing nanoparticles into the Gulf. Full Article >

Oil is not magnetic, but MIT researchers say that when mixed with water-repellent nanoparticles that contain iron, the oil can be magnetically separated from the water. The nanoparticles can later be removed to enable the re-use of the oil. Full Artice>
Drinking Water From the Charles River? Nanotech Filters Make it Possible

Three mobile laboratories will monitor river water, after which data will be analysed at a new research centre. The laboratories will then be mobilised to expand the project to other areas of the country. More>>>
Feynman and the Futurists
Richard Feynman and Nanotechnology
The Wall Street Journal, January 8, 2010
On Dec. 29, 1959, Richard P. Feynman gave an after-dinner talk at an annual American Physical Society meeting in Pasadena, Calif. Feynman was not the public figure he would later become—he had not yet received a Nobel Prize, unraveled the cause of the Challenger accident, written witty books of popular science, or been the subject of biographies, documentaries and even a play starring Alan Alda. But the 41-year-old was already respected by fellow physicists for his originality, his crackling intellect, and his roguish charm.

"Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers (nm), where unique phenomena enable novel applications not feasible when working with bulk materials or even with single atoms or molecules. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter."
"Researchers seeking to understand the fundamentals of properties at the nanoscale call their work nanoscience; those focused on effective use of the properties call their work nanoengineering."
"Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at the nanoscale." From www.nano.gov
