Ion–Molecule Reaction Products as Probes and Precursors for Preparative Mass Spectrometry
Chemistry – A European Journal, EarlyView.Ion–molecule reactions in the gas phase of mass spectrometers are important for preparative mass spectrometry because they (1) provide knowledge about the intrinsic reactivity of ions, helping to predict and control their reactivity at interfaces, and (2) generate new complex ions that can be mass selected and deposited on surfaces.

Ring Formation in Sesquiterpene Synthesis: Biomimetic vs. Non‐Biomimetic Strategies
European Journal of Organic Chemistry, EarlyView.A short review of cyclase enzyme‐mediated ring formation in sesquiterpene biosynthesis is presented as a prelude to six case studies examining the merits and demerits of biomimetic vs. non‐biomimetic strategies for carbocyclisation in the total synthesis of this iconic natural product class.

Evaluation of neutron nuclear data on iodine isotopes [PDF]
Journal of Nuclear Science and Technology, 2015 Neutron nuclear data on six isotopes of iodine have been evaluated for the next version of Japanese Evaluated Nuclear Data Library (JENDL) general-purpose file in the energy region from 10−5 eV to 20 MeV. Unresolved resonance parameters were obtained by fitting to the total and capture cross sections calculated from nuclear models, while resolved ...

International Journal of Cancer, EarlyView.What's New? The 1986 Chernobyl accident led to widespread radioactive contamination across parts of Europe, with elevated childhood leukaemia rates observed in heavily affected areas of Ukraine. Data on long‐term haematological and other non‐thyroid cancer risk in the general population in heavily contaminated regions, however, remain limited.
