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. https://www.laboratory-journal.com/news/scientific-news/arsenic-electronics Mon, 15 Oct 2018 14:03:00 +0000 Link between Gut Flora and Multiple Sclerosis Discovered https://www.laboratory-journal.com/news/scientific-news/link-between-gut-flora-and-multiple-sclerosis-discovered Multiple sclerosis is an autoimmune disease in which the body’s own immune system attacks and damages the protective coating around nerve cells. This coating is made up of myelin – a biological membrane of protein and fatty substances – which is why research efforts to find the disease’s target antigen have so far focused on the myelin membrane’s components. https://www.laboratory-journal.com/news/scientific-news/link-between-gut-flora-and-multiple-sclerosis-discovered Mon, 15 Oct 2018 13:54:00 +0000 Blue Phosphorus: Mapped and Measured for the First Time https://www.laboratory-journal.com/news/scientific-news/blue-phosphorus-mapped-and-measured-first-time The element phosphorus can exist in various allotropes and changes its properties with each new form. 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. https://www.laboratory-journal.com/news/scientific-news/blue-phosphorus-mapped-and-measured-first-time Mon, 15 Oct 2018 13:43:00 +0000 Creating Molecules for Drug Development https://www.laboratory-journal.com/news/scientific-news/creating-molecules-drug-development Chemists at The Ohio State University have developed a new and improved way to generate molecules that can enable the design of new types of synthetic drugs.

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. https://www.laboratory-journal.com/news/scientific-news/fighting-forgetfulness-nanotechnology Wed, 10 Oct 2018 16:57:00 +0000 The Stuff that Planets Are Made of https://www.laboratory-journal.com/news/scientific-news/stuff-planets-are-made 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. https://www.laboratory-journal.com/news/scientific-news/stuff-planets-are-made Tue, 09 Oct 2018 17:49:00 +0000 Electrons Go with the Flow https://www.laboratory-journal.com/news/scientific-news/electrons-go-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. https://www.laboratory-journal.com/news/scientific-news/electrons-go-flow Tue, 09 Oct 2018 17:27:00 +0000 A MOF Rack for Ammonia https://www.laboratory-journal.com/news/scientific-news/mof-rack-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. https://www.laboratory-journal.com/news/scientific-news/mof-rack-ammonia Mon, 08 Oct 2018 12:12:00 +0000 Global Sea Level Could Rise 50 Feet by 2300 https://www.laboratory-journal.com/news/scientific-news/global-sea-level-could-rise-50-feet-2300 Global average sea-level could rise by nearly 8 feet by 2100 and 50 feet by 2300 if greenhouse gas emissions remain high and humanity proves unlucky, according to a review of sea-level change and projections by Rutgers and other scientists. https://www.laboratory-journal.com/news/scientific-news/global-sea-level-could-rise-50-feet-2300 Mon, 08 Oct 2018 09:01:00 +0000 Data Exchange in the Laboratory of the Future https://www.laboratory-journal.com/science/information-technology-it/data-exchange-laboratory-future Open data formats such as AnIML and communication protocols such as SiLA help to connect up a digital laboratory.

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. https://www.laboratory-journal.com/news/scientific-news/chemists-discover-unexpected-enzyme-structure Thu, 04 Oct 2018 15:37:00 +0000 Molecular Multitools https://www.laboratory-journal.com/news/scientific-news/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. https://www.laboratory-journal.com/news/scientific-news/molecular-multitools Thu, 04 Oct 2018 15:32:00 +0000 Stepping Toward a Smaller Carbon Footprint https://www.laboratory-journal.com/news/scientific-news/stepping-toward-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. There is currently no economically or energy efficient way to collect CO2 from the atmosphere and use it to produce carbon-based chemicals, but researchers at the University of Pittsburgh Swanson School of Engineering have just taken an important step in that direction. https://www.laboratory-journal.com/news/scientific-news/stepping-toward-smaller-carbon-footprint Wed, 03 Oct 2018 15:35:00 +0000 Glowing Rapid Test for Infectious Diseases https://www.laboratory-journal.com/news/scientific-news/glowing-rapid-test-infectious-diseases Researchers from Eindhoven University of Technology (The Netherlands) and Keio University (Japan) present a practicable and reliable way to test for infectious diseases.
