Counting with fingers, I would quote the following areas of activity:

1. Relativistic effects in heavy-element chemistry. Here, paper [300] covers some fundamental aspects and paper [301] lists a sample of both classical and new chemical examples. Both appeared 2012. A Periodic Table up to Z=172 [296] was published in 2011. 2. Understanding the "metallophilic attraction" between closed-shell metal ions, such as Au(I), as a dispersion (van der Waals) effect. The two latest papers are [295], [297].

3. Predicting new, simple chemical species. A summary of our past activity is available in the review [305].

4. Simple understanding of chemical bonding. Perhaps the simplest procedure with real predictive value are the additive covalent radii, R(AB) = r_A + r_B. We have redone such fits, up to the superheavies, for single, double and triple bonds in molecules. The latest item is the set of tetrahedral covalent radii for crystals [302]. Another recent problem is the search for the high magic electron count of 32, after Lewis' octets and Langmuir's 18-electron principle. We now have identified several such series, obviously with actinides as the central atom. New chemical analogies between elements (O/Pt, N/Ir). Stereochemistry of uranyl.

5. New, fully numerical calculation methods for molecules. These accurate electric-field gradient calculations, combined with spectroscopic data, made possible new determinations of nuclear quadrupole moments, Q. The latest summary of Q-values is the 2008 one [275]. Relativistic theories of NMR parameters.
