Limit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition - directly where they arise.
In a speech today at the Commonwealth Club in San Francisco, U.S. EPA Administrator Lisa Jackson announced core principles that outline the Obama Administration?s goals for legislative reform of this country's chemical management law, the 1976 Toxic Substances Control Act, TSCA.
Scientists in the United Kingdom are reporting an advance toward overcoming one of the key challenges in nanotechnology: Getting molecules to move quickly in a desired direction without help from outside forces.
Die geheimnisvolle Antimaterie ist nicht nur exotisches Beiwerk in Kinofilmen wie 'Illuminati', sondern auch ein faszinierendes Wissenschaftsgebiet. An der Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II) der Technischen Universitaet Muenchen werden die Antiteilchen von Elektronen gewonnen, die so genannten Positronen, und das in der weltweit hoechsten Intensitaet.
Total and Laboratoire de Physique des Interfaces et des Couches Minces (LPICM), a joint R+D research team between the French National Center for Scientific Research (CNRS) and France's Ecole Polytechnique engineering school, today announce the creation of a joint research team focusing on thin film technologies for photovoltaic solar applications.
Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis.
New research announced today by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture.
