By W. Zhu, J.P. Winterstein, W.D. Yang, L. Yuan, R. Sharma and G. Zhou – Using a state-of-the-art microscopy technique, experimenters at the National Institute of Standards and Technology (NIST) and their colleagues have witnessed a slow-motion, atomic-scale transformation of rust—iron oxide—back to pure iron metal, in all of its chemical steps.
In a new effort to study the microscopic details of metal oxide reduction, researchers used a specially adapted transmission electron microscope (TEM) at NIST’s NanoLab facility to document the step-by-step transformation of nanocrystals of the iron oxide hematite (Fe2O3) to the iron oxide magnetite (Fe3O4), and finally to iron metal.
By lowering the temperature of the reaction and decreasing the pressure of the hydrogen gas that acted as the reducing agent, the scientists slowed down the reduction process so that it could be captured with an environmental TEM—a specially configured TEM that can study both solids and gas. The instrument enables researchers to perform atomic-resolution imaging of a sample under real-life conditions—in this case the gaseous environment necessary for iron oxides to undergo reduction–rather than under the vacuum needed in ordinary TEMs. more> https://goo.gl/8lJIAH

By Tim Fernholz – While the US taxes imported cars and cars parts at a maximum of 2.5%, China charges tariffs of between 21% and 30%. This gives foreign automakers who want to sell in China a big incentive to manufacture there to avoid the import charge. But China also requires foreign subsidiaries to operate as 50-50 joint ventures with Chinese companies. These, of course, then become classrooms for Chinese engineers to gain foreign know-how.
This isn’t exactly anyone’s definition of “fair” trade, but there is a logic to the situation. The system came into play in 2001, after China joined the World Trade Organization. At the time, Chinese industry was much further behind America’s. The idea was that future rounds of WTO negotiations would lower China’s trade barriers further, but global trade talks have stagnated completely.
Ironically enough, therefore, this “unfair” situation for America is a product of globalization’s stumbles, not the unyielding march forward that the Trump administration portrays it as.
And any attempts to convince China to drop its protections will now be coming from the most protectionist American administration in recent memory. more> https://goo.gl/7Supvh
