SVD-aided non-orthogonal decomposition (SANOD) method to exploit prior knowledge of spectral components in the analysis of time-resolved data

Structural Dynamics, 2019
Analysis of time-resolved data typically involves discriminating noise against the signal and extracting time-independent components and their time-dependent contributions.

Nitrogen-doped porous carbon nanosheets as both anode and cathode for advanced potassium-ion hybrid capacitors

Green Energy & Environment, 2023
Potassium-ion hybrid capacitors (PIHCs) as a burgeoning research hotspot are an ideal replacement for lithium-ion hybrid capacitors (LIHCs). Here, we report nitrogen-doped porous carbon nanosheets (NPCNs) with enlarged interlayer spacing, abundant ...

Peripheral chemical reactions

Chemical Physics Letters, 1993
Abstract Forward scattering of the products of direct exoergic atom transfer reactions is proposed as an indication for a peripheral attraction: a reaction in which an atom at the periphery of the reactants is abstracted. Model computations for the O( 1 D) + N 2 O reaction are used to illustrate the proposed mechanism. The opacity function has a peak

International chemical identifier for chemical reactions [PDF]

Journal of Cheminformatics, 2013
An open-access software for creating a unique, text-based identifier for reactions (RInChI) was developed by the Goodman group at the University of Cambridge, based on the IUPAC International Chemical Identifier (InChI) standard. RInChIs describe the substances (reactants, products, reagents and solvents) participating in a reaction with their ...

Boosting hot electron flux and catalytic activity at metal–oxide interfaces of PtCo bimetallic nanoparticles

Nature Communications, 2018
The real-time quantitative detection of hot electrons provides critical clues to understand the origin of the enhanced catalytic performance of bimetallic nanoparticles (NPs).

Automatic discovery of chemical reactions using imposed activation

, 2020
Computational power and quantum chemical methods have improved immensely since computers were first applied to the study of reactivity, but the de novo prediction of chemical reactions has remained challenging.

Lattice Tuning of Copper Single‐Crystal Surface for Electrochemical Carbon Monoxide Coupling Reaction: A Density Functional Theory Simulation

ChemElectroChem, 2023
CO is a key intermediate of electrocatalytic CO2 reduction reaction, which determines the product species. Understanding the effect of metal electrode structure on the adsorption ability and reaction activity of CO is helpful for the design of high ...

DIFFUSIVE INSTABILITIES AND CHEMICAL REACTIONS [PDF]

International Journal of Bifurcation and Chaos, 2002
Diffusive instabilities provide the engine for an ever increasing number of dissipative structures. In this class autocatalytic chemical systems are prone to generate temporal and spatial self-organization phenomena. The development of open spatial reactors and the subsequent discovery in 1989 of the stationary reaction–diffusion patterns predicted by ...

Concordant chemical reaction networks [PDF]

Mathematical Biosciences, 2012
We describe a large class of chemical reaction networks, those endowed with a subtle structural property called concordance. We show that the class of concordant networks coincides precisely with the class of networks which, when taken with any weakly monotonic kinetics, invariably give rise to kinetic systems that are injective --- a quality that ...
