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.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
