Studying the Ingress of Ag Nanoparticles into Imprinted Nanocavities by Nanoimpact Electrochemistry
ChemElectroChem, EarlyView.The ingress of single silver nanoparticles (NPs) into nanocavities is studied by nanoimpact electrochemistry. The NP‐imprinted matrix approach is used to create well‐defined nanocavities that reuptake selectively silver NPs based on their size as detected by the current–time oxidation transients of single NPs.

Nitrates in surface waters, inputs and seasonality: Progress report for the period April - December 1987 [PDF]
, 1988 The objective of this short project progress report is to investigate, in a catchment on which earlier nitrate data are available for comparison, seasonality and budgets, in relation to land use, of nitrate inputs, concentrations and loads.

Chemistry – A European Journal, Accepted Article.Cysteine (Cys) thiolate coordination is a unique ligation motif found in heme enzymes and small molecule sensors. Divergence between these two functional classes of heme thiolate proteins is a result of distinct hydrogen bonding interactions with the axial Cys(thiolate) ligand.

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties
Chemistry – A European Journal, EarlyView.Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

Chemistry – A European Journal, Accepted Article.The direct radical arylation of tyrosine residues in peptides has been achieved under highly attractive conditions, requiring only the peptide substrate, a 3,4,5‐trifluorophenyldiazonium salt and irradiation with visible light. Being well‐balanced in its reactivity to form strong charge transfer complexes with the phenolic side chain, which are ...

Chemistry – A European Journal, EarlyView.Photoswitchable azo ligands can be conjugated to the surface of ultrasmall gold nanoparticles with a high density (about 50 ligands on each nanoparticle). Their photoswitching is not constrained by the binding to the gold surface and can be used to induce a nematic‐to‐isotropic phase transition in a liquid crystal.

Endogenous N-nitroso compounds, and their precursors, present in bacon, do not initiate or promote aberrant crypt foci in the colon of rats [PDF]
, 2000 Processed meat intake is associated with increased risk of colorectal cancer. This association may be explained by the endogenous formation of N-nitroso compounds (NOC).
