Pulsations powered by hydrogen shell burning in white dwarfs [PDF]

open access: yes, 2016
In the absence of a third dredge-up episode during the asymptotic giant branch phase, white dwarf models evolved from low-metallicity progenitors have a thick hydrogen envelope, which makes hydrogen shell burning be the most important energy source.

Millipede (Diplopoda) distributions: A review

open access: yesSoil Organisms, 2009
In spite of the basic morphological and ecological monotony, integrity and conservatism expressed through only a small number of morphotypes and life forms in Diplopoda, among which the juloid morphotype and the stratobiont life form are dominant, most ...

Establishing Indium in Frustrated Lewis Pair Chemistry: From Synthesis to Catalytic Applications

open access: yesChemistryEurope, EarlyView.
Not that hard: The effects of chemical hardness of the soft FLP tBu2InCH2PtBu2 and its pyridine‐adduct tBu2In(py)CH2PtBu2 were examined in adduct formation reactions toward H2, CO2, and CS2. The frustrated Lewis pair shows catalytic activity in the reduction of CO2 with pinacolborane.

Asteroseismological study of massive ZZ Ceti stars with fully evolutionary models [PDF]

open access: yes, 2013
We present the first asteroseismological study for 42 massive ZZ Ceti stars based on a large set of fully evolutionary carbon$-$oxygen core DA white dwarf models characterized by a detailed and consistent chemical inner profile for the core and the ...

(2‐Phosphinophenyl)aluminum Dichloride Complexes as Intramolecular Al/P Frustrated Lewis Pairs for Ketone, Ester, and Imine Activation

open access: yesChemistry – A European Journal, EarlyView.
Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (
