Recent studies suggest that an atmospheric compound derived primarily from coal combustion may have contradictory effects on the earths climate.
Under many conditions, sulfuric acid may cool the earths atmosphere. Sulfuric acid particles seem to scatter ultraviolet light back into space before it has a change to enter the troposphere – the bottom layer of earths atmosphere. But if conditions are right, this same chemical can warm the earth by combining with other compounds in the atmosphere to form clouds.
Researchers at Ohio State University looked at the interaction of sulfuric acid and methanol and what the compounds combined effect might mean to global climate change. Both compounds are usually found in aerosol form in the upper atmosphere.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
