Today, such two-dimensional materials are no longer limited to carbon and are hot prospects for many applications, especially in microelectronics. In the journal Angewandte Chemie, scientists have now introduced a new 2D material: they successfully modified arsenene (arsenic in a graphene-like structure) with chloromethylene groups.

So far, red, violet, white and black phosphorus have been known. While some phosphorus compounds are essential for life, white phosphorus is poisonous and inflammable and black phosphorus - on the contrary - particularly robust. Now, another allotrope has been identified.

In an international collaboration, scientists of the Max Planck Institute for Polymer Research (MPI-P) in Mainz together with teams from Italy, Great Britain, Belgium and the USA are now working together on an approach for a therapy. On the one hand, the goal is to understand the processes occurring in the brain that lead to the disease; on the other hand the development of a method for targeted drug delivery. Wed, 10 Oct 2018 16:57:00 +0000 The Stuff that Planets Are Made of Is there a second Earth out there in space? Our knowledge of planetary systems far, far away is increasing constantly, as new technologies continue to sharpen our gaze into space. To date, 3,700 planets have already been discovered outside our solar system. The planetary masses and radii of these exoplanets can be used to infer their mean density, but not their exact chemical composition and structure. The intriguing question about what these planets could look like is thus still open. Tue, 09 Oct 2018 17:49:00 +0000 Electrons Go with the Flow You turn on a switch and the light switches on because electricity "flows". The usual perception is that this is like opening a faucet and the water starts to flow. But this analogy is misleading. The flow of water is determined by the theory of hydrodynamics, where the behavior of the fluid requires no knowledge of the movements of individual molecules. Tue, 09 Oct 2018 17:27:00 +0000 A MOF Rack for Ammonia Handling, storing, and shipping of ammonia requires costly equipment and special precautions because of its inherent corrosiveness and toxicity. Scientists in Manchester, UK, have found that a metal–organic framework, MFM-300(Al), a porous solid, not only effectively filters harmful nitrogen dioxide gas, but it also has outstanding capabilities for ammonia storage.

Fri, 05 Oct 2018 15:22:00 +0000 Chemists Discover Unexpected Enzyme Structure CAMBRIDGE, MA -- Many microbes have an enzyme that can convert carbon dioxide to carbon monoxide. This reaction is critical for building carbon compounds and generating energy, particularly for bacteria that live in oxygen-free environments. This enzyme is also of great interest to researchers who want to find new ways to remove greenhouse gases from the atmosphere and turn them into useful carbon-containing compounds. Current industrial methods for transforming carbon dioxide are very energy-intensive. Thu, 04 Oct 2018 15:37:00 +0000 Molecular Multitools The functionalization of surfaces with different physical or chemical properties is a key challenge for many applications. For example, the defined structuring of a surface with hydrophobic and hydrophilic areas can be used for the separation of emulsions, like water and oil. However, the creation of user-defined surface properties is a challenge. Thu, 04 Oct 2018 15:32:00 +0000 Stepping Toward a Smaller Carbon Footprint Burning fossil fuels such as coal and natural gas releases carbon into the atmosphere as CO2 while the production of methanol and other valuable fuels and chemicals requires a supply of carbon.
