Experimental evidence has demonstrated that the presence of water in non-aqueous electrolytes significantly affects Li-O2 electrochemistry. Understanding the reaction mechanism for Li2O2 formation in the presence of water impurities is...

The Dutch preposition door can be translated with through (typically in adverbial clauses of time/place) or by (typically as a marker for the passive agent and the causee). The choice between these two seems at first sight not to be very difficult for Dutch learners of English. This should come as no surprise if we assume — along with more traditional semantic descriptions of door — that there are two homonymous door's. However, we would like to propose that there is only one, polysemous door. After briefly looking at theoretical evidence from cognitive semantics for this proposal, we discuss experimental evidence from learners' translations of door. The results of the experiment show that the translation of door is not as easy as could have been expected. Indeed, when learners translate door as if there were two door's, they run into interesting difficulties. This seems to suggest that (1) learners would benefit from treating door as one, polysemous word and (2) that (theories of) (foreign) language learning and teaching could benefit from cognitive semantic insights.

Abstract We fully support dissociating the subjective experience from the memory contents in recognition memory, as Bastin et al. posit in the target article. However, having two generic memory modules with qualitatively different functions is not mandatory and is in fact inconsistent with experimental evidence. We propose that quantitative differences in the properties of the memory modules can account for the apparent dissociation of recollection and familiarity along anatomical lines.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.
