France and the United States Jointly Study the Environmental Impact of Nanoparticles To strengthen cooperation between teams of scientists and jointly study the impact of nanoparticles on the environment, France and the United States plan to establish an "International Research Alliance for Environmental Impact of Nanotechnology" to further strengthen the two countries ’nanotechnology The field has established a cooperative relationship since 2001. The research alliance includes 9 laboratories including the French National Academy of Sciences and the Atomic Energy Commission; the US has 8 laboratories participating. The main goal of the research is to understand and predict the environmental impact of nanoparticles, with an emphasis on understanding the potential environmental impact of nanomaterial manufacturers. Cooperative research is devoted to preventing the possible harms of nanotechnology, thereby guiding the healthy development of nanotechnology. The following scientific issues are involved: one is the aging of nanomaterials or nanoparticles, the degradation of various substrates, salting out; the second is the conversion mode of nanoparticles in the environment (air, water, porous media); the third is the nanoparticle toxicity test method Standardization; four is the reaction of cells and organisms after contact with nanoparticles; fifth is the change of ecosystems after contact with nanoparticles. Research on the potential impact of nanotechnology in France involves government departments such as the Ministry of Research, the Ministry of Ecology, the Ministry of Industry, and the Ministry of Health, as well as national research institutions such as the National Academy of Sciences, the Atomic Energy Commission, and the National Research Agency. The research activities involve: the toxicity research of nano powders; the safety production research of nano materials; the ethics and legal research related to nano technology. France has initiated research on the potential impact of nanotechnology to develop the rational interaction between nanotechnology and society. The cooperative research between France and the United States will undoubtedly make the research work on nanotechnology more comprehensive.
BBQ Grill
A
BBQ grill is a cooking appliance used for outdoor cooking, specifically
for grilling food over an open flame or hot coals. It typically
consists of a metal grate or griddle that is placed over a heat source,
such as charcoal or propane gas. The grill can be used to cook a variety
of foods, including meats, vegetables, and seafood. BBQ grills come in
different sizes and styles, including portable models for camping or
tailgating, and larger models for backyard entertaining. Some BBQ grills
also include additional features such as side burners, rotisserie
attachments, and temperature gauges.
