Here, we explore the use of operando confocal Raman microscopy to investigate and quantify Li–S redox processes, based on both potentiostatic and galvanostatic measurements, achieving a detailed characterization of their reaction pathways and kinetics. By visualizing the potential-dependent reactants and...
The rational design of heterogeneous catalysts relies on the efficient survey of mechanisms by density functional theory (DFT). However, massive reaction networks cannot be sampled effectively as they grow exponentially with the size of reactants. Here we present a statistical principal component analys...
4c. The pore and throat network of the electrode refers to the interconnected system of void spaces (pores) and narrow channels (throats) within the electrode structure. These features facilitate the transport of reactants and products during electrochemical reactions within the fuel cell electrode....
The increased number of structures leads, however, to a combinatorial explosion in a brute-force exploration of all possible reactive site combinations, which prohibits the exhaustive exploration the reactivity of even moderately sized structures5. Based on their determination of reactive sites, automated...
Jiandi Wan of Rochester Institute of Technology is mimicking not only the system but the physiology of photosynthesizers by utilizing microfluidics and photochemistry to produce solar fuels. By emulating the small fluid channels seen in leaves, the device forces the reactants (CO2 and water) into...
derive the Arrhenius empirical equation and seek the nature of Ea.This paper endeavors to derive the Arrhenius empirical equations grounded upon the thermodynamic theory,and ultimately confirms that the Ea is the Gibbs free energy of resultant (-Gom,B) or Gibbs free energy of reactant (-Gom,B...

In this paper, we quantitatively interpret the Molecular Transformer, the state-of-the-art model for reaction prediction. We develop a framework to attribute predicted reaction outcomes both to specific parts of reactants, and to reactions in the training set. Furthermore, we demonstrate how to ...
However, the majority of these reactants necessitate operations at very high temperatures and the mechanism does not always prove to be a nucleophilic substitution. Moreover, the departure of the nitro group leads to the formation of oxygenated and halogenated derivatives of nitrogen, which are ...
