Ultrathin covalent organic overlayers on metal nanocrystals for highly selective plasmonic photocatalysis

Nature Communications, 2023
Metal nanoparticle-organic interfaces are common but remain elusive for controlling reactions due to the complex interactions of randomly formed ligand-layers.

Kinetic Highlights of the Reduction of Silver Tungstate by Mg + C Combined Reducer

Metals, 2022
The programmed reduction of tungstates and molybdates may yield the production of an intimate mixture of metals, pseudo-alloys or composite powders. As an extension of the study of obtaining powders of tungsten-copper, molybdenum-copper and tungsten ...

Stochastic Chemical Reactions in Micro-domains

, 2004
Traditional chemical kinetics may be inappropriate to describe chemical reactions in micro-domains involving only a small number of substrate and reactant molecules.

Designing covalent organic frameworks with Co-O4 atomic sites for efficient CO2 photoreduction

Nature Communications, 2023
A class of inexpensive aminoanthraquinone organic dyes are shown to facilitate visible-light-driven CO2 reduction. Overall reaction efficiencies were found to be optimal when both electron donating and accepting groups were on a single dye molecule.

Non-invasive estimation of dissipation from non-equilibrium fluctuations in chemical reactions

, 2013
We show how to extract from a sufficiently long time series of stationary fluctuations of chemical reactions an estimate of the entropy production. This method, which is based on recent work on fluctuation theorems, is direct, non-invasive, does not ...

Universality and chaoticity in ultracold K+KRb chemical reactions [PDF]

Nature Communications, 2017
A fundamental question in the study of chemical reactions is how reactions proceed at a collision energy close to absolute zero. This question is no longer hypothetical: quantum degenerate gases of atoms and molecules can now be created at temperatures ...

Colloidal zinc oxide-copper(I) oxide nanocatalysts for selective aqueous photocatalytic carbon dioxide conversion into methane

Nature Communications, 2017
Photocatalytic reduction and oxidation reactions, involving multiple electrons and operating in tandem, are extremely challenging to achieve. Here, with a hybrid structure of ZnO and Cu2O, the authors report photocatalytic carbon dioxide reduction to ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
