Research conducted by scientists at Brown University, United States, has found that nanoparticles of nickel can trigger a cellular pathway that promotes cancer growth.

While organic photovoltaic solar cells have a wide range of potential applications, they still lag behind conventional solar cells in their ability to efficiently convert sunlight into electricity.

Researchers at the Massachusetts Institute of Technology (MIT), United States, have discovered a new way to analyze how coatings of tiny particles alter the properties of transparent plastic.

The field of “cognitive computing” continues to progress, with IBM announcing this week two prototype cognitive computer chips.

Mitra Karani, of the toxicology department of the Medical Science University of Tehran, Iran, said caution should be taken in using products containing nanosilver that come in contact with the skin.

Phosphorus from point sources, such as wastewater treatment plants, and non-point sources, such as runoff from agricultural farms and urban areas, has caused a significant water quality problem in the United States.

Chinese chemists are obsessed with journal impact factors, to the detriment of the field, says Nai-Xing Wang, a professor in the Technical Institute of Physics and Chemistry at the Chinese Academy of Sciences, Beijing.

A group of researchers is looking to regenerate bones with materials of natural origin, such as wood.

Engineers at the Massachusetts Institute of Technology (MIT), United States, have developed a way to make microparticles of nearly any shape.

While carbon nanotubes offer great promise, especially since they can theoretically carry 1,000 times more electric current than a metal conductor of the same size, new research conducted by the United States National Institute of Standards and Technology (NIST) suggests

Two start-ups, Nexeon in the United Kingdom, and Amprius, in the United States, have, by swapping graphite for silicon as an electrode material, made lithium-ion batteries that can hold double the energy they do today.

Scientists at the United States Department of Energy’s Oak Ridge National Laboratory are using a novel microscopy method to probe the reactions that limit the widespread deployment of fuel cell technologies.

The Brazilian government and the Chinese Academy of Sciences will this month sign an agreement for construction of a nanotechnology center in the Brazilian state of Sao Paulo.

Andrew Ranallo, the communications associate at the Institute for Agriculture and Trade Policy (IATP), writes, “The U.S. food system has a new bedfellow, and it may already be on your plate.”

More and more manufacturers have reduced particle sizes in their sunscreens to the nanoscale – causing the particles to be more transparent – and avoiding the white, pasty appearance of sunscreens that use large particles.

The United States National Nanotechnology Initiative (NNI) has posted the presentations from its March 2011 workshop, “US-EU: Bridging NanoEHS Research Efforts,” to its website.

The American Chemical Society’s Chemistry Institute® (ACS GCI) and the Oregon Nanoscience and Microtechologies Institute, both in the United States, have developed a roadmap to ensure nanotechnologies are safe for use by humans before they are introduced to the marketplace.

The scientific think tank Matter says that industry must learn crucial communication lessons from past “techno disasters” such as genetically modified foods (GM) and asbestos if new technologies such as nanotechnology are to be accepted by consumers.
