How many water molecules does it take to dissolve hydrochloric acid?

13-Jun-2024 - Scientists from DESY have made a significant step towards understanding the solvation processes of hydrochloric acid (HCl) at the molecular scale. HCI is a prototypical acid that is often used for research and in industry and also plays a part in atmospheric chemistry – for example in the growth ...

New Methodology for anti-Markovnikow products

This might be helpful to tackle synthesis problems

23-Feb-2023 - Vladimir Vasilyevich Markovnikov was a 19th century Russian chemist who worked at the universities of St. Petersburg, Odessa and Moscow, among others. The so-called Markovnikov rule, well known already with young students of chemistry, is named after him. This rule says that when protic acids are ...

Hydrochloric acid boosts catalyst activity

Hydrochloric acid treatment improves catalysts for removing sulfur from crude oil

27-Aug-2020 - A research team from the Technical University of Munich (TUM) led by chemist Johannes Lercher has developed a synthesis process which drastically increases the activity of catalysts for the desulfurization of crude oil. The new process could perhaps also be used for catalysts in fuel cells. Crude ...

How acids behave in ultracold interstellar space

12-Jun-2019 - Solvated acids tend to release a proton. However, they display more complex behaviour under space conditions. Bochum-based researchers from the Cluster of Excellence Ruhr Explores Solvation (Resolv), together with cooperation partners from Nijmegen, have investigated how acids interact with water ...

Self-folding origami

Chemical "programming" to induce Nafion foil to fold itself

26-Jun-2017 - Plastic with a thousand faces: A single piece of Nafion foil makes it possible to produce a broad palette of complex 3D structures. Researchers describe how they use simple chemical "programming" to induce the foil to fold itself using origami and kirigami principles. These folds can be ...

A more sustainable way to refine metals

08-Jun-2017 - A team of chemists in Canada has developed a way to process metals without using toxic solvents and reagents. The system, which also consumes far less energy than conventional techniques, could greatly shrink the environmental impact of producing metals from raw materials or from post-consumer ...

Making vanilla flavoring with less pollution

16-Mar-2017 - In small amounts, vanilla flavoring enhances the taste of our baked goods, desserts and ice cream. But making it synthetically, which is the most common route to keeping the ingredient affordable these days, creates a stream of wastewater that requires treatment before it can be released into ...

A jelly-based fuel cell

05-Dec-2013 - An international team of researchers has used gelatin as their starting material to make a fuel cell catalyst. The team used gelatin to make doped-carbon electrocatalysts that could be a potential replacement for platinum in fuel cells. To make the catalyst, they mixed iron and magnesium into ...

Cloud research at extreme altitudes

Scientists succeed in the world's first aerosol particle sampling from polar stratospheric clouds for a better understanding of ozone depletion

09-Jan-2012 - Polar stratospheric clouds are crucially involved in the formation of the ozone hole. In order to explore their development, measurements at extreme altitudes are needed. This is what researchers from Mainz and Darmstadt have performed last December over northern Sweden. At 20 kilometers altitude ...

UCI scientists discover ozone-boosting chemical reaction

Newfound chemistry should be added to atmospheric models, researchers say

22-Jul-2009 - Burning of fossil fuels pumps chemicals into the air that react on surfaces such as buildings and roads to create photochemical smog-forming chlorine atoms, UC Irvine scientists report in a new study. Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts ...
