Soares, Lages, Oliveira, and Cabrera-Hernández (2019) recently showed that the mirror-letter interference effect observed for words containing reversal letters was reliable for words containing left-oriented mirror-letters as 'd', but not for words containing right-oriented mirror-letters as 'b', thus indicating that the directionality of the reversal letters cannot be disregarded when examining the cost of suppressing the mirror-generalization mechanism at the early stages of visual word recognition. Here we examined whether this bias can also be observed for left-oriented non-reversal letters such as 'g', 'j', and 'z', which just as 'd' are also prone to errors in writing in left-to-right orthographies as European Portuguese (EP). Thirty-six EP skilled readers performed a lexical decision task combined with a masked-priming paradigm in which target words containing either left-oriented (e.g., 'g', genial) or right-oriented (e.g., 'c', casual) non-reversal letters were preceded by 50 ms primes that could be the same as the target (genial-genial, casual-casual), nonword primes in which the critical letter was replaced by the mirror-image of the left- or right-oriented non-reversal letter ([reverse g]enial-genial, [reverse c]asual-casual), or nonword primes in which the critical letter was replaced by the mirror-image of another left-oriented or right-oriented non-reversal letter as control ([character omitted]enial-genial, [character omitted]asual-casual). Results showed that the amount of priming produced by identity primes and mirror-image primes was virtually the same for words with left-oriented (e.g., genial-genial = [reverse g]enial-genial), but not for words with right-oriented non-reversal letters (e.g., casual-casual > [reverse c]asual-casual), hence extending the right-oriented bias observed for words containing reversal letters to words containing non-reversal letters.

[Au(dspdt)2] (dspdt = 2,3-dihydro-5,6-selenophenedithiolate) is an unprecedented example of a neutral gold bisdithiolene complex with a unique structure composed of interacting dimer and trimer chains displaying relatively high electrical conductivity (0.1 S cm−1 at room temperature).

The synthesis, characterisation and application as electron-acceptors in organic photovoltaic cells of new [1,2,5]thiadiazolo[3,4-g]quinoxaline-based small molecules with oligo(ethylene oxide) solubilising groups and tunable optical bandgaps are reported. A new p-type polymer consisting of a polythiophene derivative substituted with analogous solubilising groups was also synthesised to perform as a donor, in combination with the small molecules, for bulk-heterojunction solar cells using ethanol/anisole mixtures as low toxic solvents to process the active blends. Comparison of the structural, electrochemical and photophysical properties of the small molecules elucidated on the structural dependence of their optical bandgaps, ranging from 1.31 to 2.25 eV. The active layers composed of the polythiophene donor and the small molecules showed well-intermixed morphologies, and the best performing blends showed a fibrillar-type morphology, indicative of more ordered molecular packings. Blends processed from the 50 : 50 (v/v) mixture of ethanol and a low toxic solvent, anisole, yielded low power conversion efficiencies of 0.39% in non-optimized organic solar cells. Although the efficiencies are low, these are the first reported results of OSCs with active layers composed of non-fullerene acceptors processed from ethanol-based solvent formulations. This study provides guidelines for the design of non-fullerene acceptors for the fabrication of OSCs processed from environmentally friendly solvents. [ABSTRACT FROM AUTHOR]
