(Nanowerk News) Finland is a forerunner in nanotechnology, and the fast-growing field has already produced strong results. The 70 million euro Tekes FinNano programme, currently in its third year, has launched companies and new business throughout the country. Applications of nanotechnology are in widespread use in the key areas of Finnish industry.

The new material, a superlattice, which has a multilayer structure composed of alternating atomically thin layers of two different oxides (PbTiO3 and SrTiO3), possesses properties radically different to either of the two materials by themselves. These new properties are a direct consequence of the artificially layered structure and are driven by interactions at the atomic scale at the interfaces between the layers.
“Besides the immediate applications that could be generated by this nanomaterial, this discovery opens a completely new field of investigation and the possibility of new functional materials based on a new concept: interface engineering on the atomic scale,” said Dr. Dawber.

In their study, Global Industry Analysts, Inc. (GIA) notes the success of nanotechnology commercialization in the healthcare and electronics section will bolster revenues for all products incorporating nanoscale technologies over the next decade. The GIA’s report also looks at government spending in nanotechnology research and development–from 2006 to 2010, Japan will be the world leader in this category, providing about $6 Billion US for nanotech R&D. The US is not too far behind with a projected $5.6 Billion US dedicated to nanotech R&D, followed by the European Union at about $4.6 Billion US for the same period.

Abstract:
BACKGROUND: Airborne nanoparticles from vehicle emissions have been associated with adverse effects in people with pulmonary and cardiovascular disease, and toxicological studies have shown that nanoparticles can be more hazardous than their larger scale counterparts. Re-circulating air filtration in automobiles and houses may provide a low-cost solution to reducing exposures in many cases, thus reducing possible health risks.
OBJECTIVES: We investigated the effectiveness of re-circulating air filtration on reducing exposure to incidental and intentionally produced airborne nanoparticles under two scenarios: while driving in traffic, and while generating nanomaterials using gas phase synthesis.
METHODS: We tested the re-circulating air filtration in two commercial vehicles when driving in traffic, as well as in a non-ventilation room with a nanoparticle generator, simulating a nanomaterial production facility. We also measured the time-resolved aerosol size distribution during the in-car recirculation to investigate how re-circulating air filtration impacts on particles of different sizes. A recirculation model was developed to describe the aerosol concentration change during recirculation.
RESULTS: The use of inexpensive low-efficiency filters in recirculation systems is shown to reduce nanoparticle concentrations to below levels found in a typical office within three minutes while driving through heavy traffic, and within twenty minutes in a simulated nanomaterial production facility.
CONCLUSIONS: Development and application of this technology could lead to significant reductions in airborne nanoparticle exposure, reducing possible risks to health and providing solutions to generating nanomaterials safely.

Abstract
Nanotechnology presents countless opportunities to develop new and improved consumer products for the benefit of society. However, as the industrial production and use of nanotechnology products continue to expand at a fast scale, potential human health concerns and ecological safeguards for the environment need to be addressed. Health risk assessment involving different animal species for multi-organ toxicity complimented with molecular investigations in cells is essential for investigating the potential toxic effects of nanomaterials. The purpose of this review is to present the current state of knowledge regarding the potential routes of human exposure to nanomaterials and their biological health effects. Although anthropogenic nanosized particles emitted in the environment are known to produce adverse human health in susceptible populations, much remains to be explored. Exposures can occur from direct exposure or from the use of commercial products made of nanomaterials. Safe manufacturing guidelines for prevention of exposures and recommendations on safe handling and use need to be established on a proactive basis to prevent adverse outcomes.
