Affix polyfunctionality in French deverbal nominalizations

open access: yesMorphology, 2022
AbstractThis article investigates the semantic polyfunctionality of affixes, i.e. their ability to serve a variety of distinct semantic functions. Based on the analysis of a sample of 3,091 deverbal nouns ending with 46 different suffixes in French, the study examines the diversity of semantic functions realized by deverbal suffixes, the distribution ...

Coordination chemistry of perhalogenated cyclopentadienes and alkynes. 8. Pentakis(dimethylsilyl)cymantrene [PDF]

open access: yes, 1992
Starting from [q5-C5Br5]M n(CO),, the first r-complex of a cyclopentadienyl ligand with five silyl substituents, [q 5-C5(SiMe2H)5M] n(CO),, was prepared by a series of halogen-lithium exchange reactions, followed by silylation with SiMe2HCI.

Evaluating Cellular Polyfunctionality with a Novel Polyfunctionality Index

open access: yesPLoS ONE, 2012
Functional evaluation of naturally occurring or vaccination-induced T cell responses in mice, men and monkeys has in recent years advanced from single-parameter (e.g. IFN-γ-secretion) to much more complex multidimensional measurements. Co-secretion of multiple functional molecules (such as cytokines and chemokines) at the single-cell level is now ...

Gold nanoparticles/silver-bipyridine hybrid nanobelts with tuned peroxidase-like activity [PDF]

open access: yes, 2016
Gold nanoparticles-decorated silver-bipyridine coordination polymers with intrinsic peroxidase-like activity are reported. Both morphology and mimetic enzyme activity can be tuned by rational manipulation of the nanohybrid composition.
