Sulfurous acid H2SO3 - and it does exist

World's first proof under atmospheric conditions calls textbook opinion into question

05-Sep-2024 - Once again, the atmosphere amazes us with its diverse chemical processes. For the first time, researchers at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig have demonstrated the existence of sulfurous acid (H2SO3) under atmospheric conditions in the gas phase. The results ...

Shedding light on the chemical enigma of sulfur trioxide in the atmosphere

30-May-2024 - Researchers at Tampere University have discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to ...

Chemical triad forms seeds for clouds

Synergistic particle formation in the upper troposphere by nitric acid, sulfuric acid and ammonia

20-May-2022 - Atmospheric aerosol particles are needed as seeds to form clouds, but the controlling processes are not fully understood. By combining experiments in the CERN cloud cham-ber and computer modelling, a team of international researchers, including scientists from the Max Planck Institute for ...

Mechanism of oxidative unzipping of multiwall carbon nanotubes to graphene nanoribbons

13-Apr-2018 - Graphene, a two-dimensional lattice of carbon atoms, has attracted enormous interest from a broad base of the research community for more than one decade. Graphene nanoribbons (GNRs), narrow strips of graphene, being quasi one-dimensional, possess complementary features relative to their ...

Combating sulphuric acid corrosion at wastewater plants

Microbial induced concrete corrosion causes massive damage to wastewater plants

26-Feb-2018 - Wastewater systems are integral to infrastructure in every community. In an ideal world, they operate smoothly and are long-lasting. But biogenic transformation processes in sewage and water treatment systems are a “natural enemy” of conventional plants, frequently causing damage to concrete and ...

Hybrid electrolyte enhances supercapacitance in vertical graphene nanosheets

08-Dec-2017 - Supercapacitors can store more energy than and are preferable to batteries because they are able to charge faster, mainly due to the vertical graphene nanosheets (VGNs) that are larger and positioned closer together. VGNs are 3-D networks of carbon nanomaterial that grow in rows of vertical ...

New hydronium-ion battery presents opportunity for more sustainable energy storage

22-Feb-2017 - A new type of battery developed by scientists at Oregon State University shows promise for sustainable, high-power energy storage. It's the world's first battery to use only hydronium ions as the charge carrier. The new battery provides an additional option for researchers, particularly in the ...

Achieving better and cheaper biodiesel

26-Sep-2013 - Is there any connection between wine and biodiesel? The answer is yes, however surprising it may seem. Acetals are chemical compounds found in many wines, like port, for example, which give it a unique, sweet smell. However if acetals are blended with biodiesel, they improve its properties. The ...
