Flow chemistry is the development and study of chemical reactions whereby reactants are combined by pumping fluids, including solutions of reagents, through tubes at known rates. The relative proportions of the reactants are controlled by their concentrations and relative flow rates. These reactions ...
Hydroxyl radicals (OH) determine the tropospheric self-cleansing capacity, thus regulating air quality and climate. However, the state-of-the-art mechanisms still underestimate OH at low nitrogen oxide and high volatile organic compound regimes even considering the latest isoprene chemistry. Here we pr...
to become an excellent support for gold nanoparticles as it offers a very high surface area for gold dispersion, with ordered mesopores large enough to accommodate gold nanoparticles in its internal and external surfaces, as well as allowing easy access of reactant molecules to the active sites. ...
Although the definition of Green Chemistry and its 12 principles are well set showing the direction on the groundwork of this area of research, the students often find it difficult to remember them correctly. Alternatively, if they are given an example of a common natural process like ...
Supplementary Table 7 provides a definition of prior distributions of the kinetic rates. tm and tl were treated as parameters only in the modeling of unrelated stable proteins; for modeling of proteins of interest (that is, MRPs and their assembly factors), they were set as constants derived ...
The reactants are hydrogen iodide (HI), carbon monoxide (CO), and methanol (H3C-OH) in aqueous solution. The catalyst is the speciesm1and the product is acetic acid. Full size image The variety of compounds involved in other (non-Rh-catalyzed) reactions imposes a challenge for existing re...
Magnetic fields can enhance electrocatalysis, yet its effect on mass transport has been overlooked. Here, the authors track the motion induced on the electrolyte ions, demonstrating that mass transport effects can double the catalyst activity with low reactant availability, as in oxygen reduction. ...
Optimizing the transport, mobility and diffusion of reactants and intermediates in a confined space can accelerate reactions. Here the authors study the reaction of highly reactive intermediates such as short-lived cationic and anionic species in a flow reactor. ...
The surge in global plastic production, reaching 400.3 million tons in 2022, has exacerbated environmental pollution, with only 11% of plastic being recycled. Catalytic recycling, particularly through hydrogenolysis and hydrocracking, offers a promising
Geological sources of H2 and abiotic CH4 have had a critical role in the evolution of our planet and the development of life and sustainability of the deep subsurface biosphere. Yet the origins of these sources are largely unconstrained. Hydration of man
