To use or not to use: Nanotechnology in sunscreens

Some sunscreens contain simple nanomaterials: nanoparticles of zinc oxide or titanium dioxide. Sunscreens have had these for decades, but the particles used to be bigger, which is why lifeguards at the beach used to have white noses. Now the particles are smaller, so the sunscreens are transparent. Applying the “nanotechnology” label to these products is… Continue reading To use or not to use: Nanotechnology in sunscreens

Food workers worried about nanotechnology

Nanowerk brings to our attention a resolution on nanotechnology by a labor group for food and agricultural workers claiming to represent 12 million people. It has a number of sections, but here’s an example: To demand that national and international patent offices, like the World Intellectual Property Organization (WIPO), decline to register all patent applications… Continue reading Food workers worried about nanotechnology

Nanotechnology vs. climate change

Engineering News tells of a study by Frost & Sullivan on how nanotechnology can make a difference in addressing the issue of climate change: The report looked at five areas where nanotechnology could be helpful, which included the areas of fuel additives, solar cells, the hydrogen economy, batteries and supercapacitors, and insulation. In terms of… Continue reading Nanotechnology vs. climate change

Nanotechnology *for* the environment

Since it was the potential environmental benefits of nanotechnology that first drew me (and many others) to an interest in the field, it’s good to see some official notice of that aspect. From Cordis via Nanowerk News: Much has been said about the potential of nanotechnologies to revolutionise the way we live, with the biggest… Continue reading Nanotechnology *for* the environment

Nanotechnology for drug detection

I tell audiences that the day is coming when nanotechnology will be able to tell what they ate or smoked. That day is coming closer, according to Nanowerk News: To this day, fingerprints are just the thing when a perpetrator needs to be arrested or a person needs to be identified. British scientists working with… Continue reading Nanotechnology for drug detection

Competing nanotechnology control frameworks

We’ve written here before about the Environmental Defense/DuPont effort to create a framework to deal with nanotechnology environmental, health, and safety (EHS) risks. Now NRDC has issued its own report and framework. An excerpt from the report: The current approach to chemical regulation cannot be relied upon to prevent harm from nanomaterials; it is slow,… Continue reading Competing nanotechnology control frameworks

Nanotechnology or not: Iron seeding of ocean seems premature at best

Regular readers of Nanodot know that we often disagree with ETC Group — but not always. They have issued a press release condemning a plan by a private firm to seed the ocean with iron particles in an effort to fight global warming. An excerpt: As worrying, Planktos boasts on their website that the iron… Continue reading Nanotechnology or not: Iron seeding of ocean seems premature at best

7th graders to clean ocean with nanotechnology

The winners of this year’s Lego engineering contest were inspired by nanotechnology concepts to design a robot to clean plastic from the ocean: For the competition, the students had to prepare a presentation on this year’s theme — nanotechnology, or molecular-size machines. They looked for a nanotech application that could clean up small, degraded plastic… Continue reading 7th graders to clean ocean with nanotechnology

"Green nanotechnology" webcast to highlight environmental benefits

If helping the environment is one of your top goals for nanotechnology — as it is for us here at Foresight — you may want to check out this Thursday’s nanotech webcast from the busy folks at the Project on Emerging Nanotechnologies at the Wilson Center. They’re releasing a new report titled “Green Nanotechnology: It’s… Continue reading "Green nanotechnology" webcast to highlight environmental benefits

Nanotechnology steel climbs mountains, beats titanium

Next time you’re heading out to climb Mount Everest, take advantage of today’s early nanotechnology and be sure to bring your nanomaterials-based ice axe: C.A.M.P. proposes an innovative, lightweight ice axe which combines a 7075 aluminium head and shaft with a point riveted to the pick, made out of innovative Sandvik Nanoflex® stainless steel. This… Continue reading Nanotechnology steel climbs mountains, beats titanium
