First-Principles-Based Multiscale Modelling of Nonoxidative Butane Dehydrogenation on CrO(0001).

Propane (CH) and butane (CH) are short straight-chain alkane molecules that are difficult to convert catalytically. Analogous to propane, butane can be dehydrogenated to butenes (also known as butylenes) or butadiene, which are used industrially as raw materials when synthesizing various chemicals (plastics, rubbers, etc.).

Chitin isolation from crustacean waste using a hybrid demineralization/DBD plasma process.

Conventional isolation of chitin from crustacean waste demands the use of high amounts of hazardous chemicals, hence not leading to a sustainable process. Atmospheric-pressure dielectric barrier discharge (DBD) plasma has demonstrated an enhanced ability to remove proteins directly from the biomass without the formation of any waste. Simultaneously, organic acids have proven very efficient in the removal of inorganic minerals from crustacean waste.

A review of plasma-assisted catalytic conversion of gaseous carbon dioxide and methane into value-added platform chemicals and fuels.

CO and CH contribute to greenhouse gas emissions, while the production of industrial base chemicals from natural gas resources is emerging as well. Such conversion processes, however, are energy-intensive and introducing a renewable and sustainable electric activation seems optimal, at least for intermediate-scale modular operation. The review thus analyses such valorisation by plasma reactor technologies and heterogeneous catalysis application, largely into higher hydrocarbon molecules, that is ethane, ethylene, acetylene, propane, , and organic oxygenated compounds, methanol, formaldehyde, formic acid and dimethyl ether.

Nighttime Aqueous-Phase Formation of Nitrocatechols in the Atmospheric Condensed Phase.

Yellow-colored methylnitrocatechols (MNC) contribute to the total organic aerosol mass and significantly alter absorption properties of the atmosphere. To date, their formation mechanisms are still not understood. In this work, the intriguing role of HNO (catalytic and oxidative) in the dark transformation of 3-methylcatechol (3MC) under atmospherically relevant aqueous-phase conditions is emphasized.
