Water adsorption and O-defect formation on Fe2O3(0001) surfaces
The stability and reactivity of the hematite, Fe2O3(0001) surface are studied by density functional theory including an on-site Coulomb term (DFT+U). Even under oxygen rich conditions, the metal-terminated surface is shown ...
A cobalt(II) iminoiodane complex and its scandium adduct
mechanistic promiscuity in hydrogen atom abstraction reactions
In addition to oxometal [Mn+[double bond, length as m-dash]O] and imidometal [Mn+[double bond, length as m-dash]NR] units, transient metal–iodosylarene [M(n−2)+–O[double bond, length as m-dash]IPh] and metal–iminoiodane ...
The Periodic Tableau
Form and Colours in the first 100 years
While symbolic colour use has always played a conspicuous role in science research and education, the use of colour in historic diagrams remains a lacuna in the history of science. Investigating the colour use in diagrams ...
PEGylated Precision Segments Based on Sequence-Defined Thiolactone Oligomers
A straightforward access route to multifunctional block copolymers, com- bining a poly(ethylene glycol) (PEG) block and a monodisperse segment with discrete monomer sequence based on thiolactone chemistry, is described.Exploiting ...
On the Morphology of Group II Metal Fluoride Nanocrystals at Finite Temperature and Partial Pressure of HF
We have investigated the bulk and surface properties of the group II metal fluorides CaF 2 , SrF 2 and BaF 2 using periodic density functional theory (DFT) calculations and surface thermodynamics. Our bulk results show ...
SERS probing of proteins in gold nanoparticle agglomerates
The collection of surface-enhanced Raman scattering (SERS) spectra of proteins and other biomolecules in complex biological samples such as animal cells has been achieved with gold nanoparticles that are introduced to the ...
Evaluating the Solvent Stark Effect from Temperature-Dependent Solvatochromic Shifts of Anthracene
The solvent Stark effect on the spectral shifts of anthracene is studied with temperature‐dependent solvatochromic measurements. The Stark contribution ΔvStark to the absorption shift Δvp in polar solvents is measured to ...
A Fast and Easy Method for Specific Detection of Circular RNA by Rolling-Circle Amplification
Let it roll: Circular RNAs (circRNAs) represent a new class of usually noncoding transcripts with largely unknown functions. Their research is hampered not least by the inapplicability of traditional analytical methods. ...
Comparing the Performance of Nb2O5 Composites with Reduced Graphene Oxide and Amorphous Carbon in Li‐ and Na‐Ion Electrochemical Storage Devices
Two‐dimensional (2D) reduced graphene oxide (rGO) is often combined with metal oxides for energy‐storage applications, owing to its unique properties. Here, we compare the electrochemical performance of Nb2O5‐rGO and ...
Healthspan Maintenance and Prevention of Parkinson’s-like Phenotypes with Hydroxytyrosol and Oleuropein Aglycone in C. elegans
Numerous studies highlighted the beneficial effects of the Mediterranean diet (MD) in maintaining health, especially during ageing. Even neurodegeneration, which is part of the natural ageing process, as well as the ...
