Conjugated polymers have been widely studied as flexible, versatile semiconductors in organic electronics. However, the material stability is one of the problems limiting their applications. Thus, understanding the degradation process of conjugated polymers is crucial. In this work, we monitored the chain scission of the model polymer MEH-PPV in chloroform solutions under different conditions by a

The rock-cut chamber tombs form a very small percentage of the rockcut tombs in Labraunda. The majority of these tombs, situated next to the sanctuary, were studied by Paul Åström in 1950 together with the sarcophagi; two improved from natural caves further from the sanctuary in both directions were found in a topographic survey conducted by Lars Karlsson in 2005, and finally one tomb at some dist

AIM: The aim of the present study was to examine the bidirectional associations between subjective role ambiguity and role conflicts at work, respectively, and self-reported sleep 2 years later. In addition, we also examine whether sense of coherence (SOC) moderate or mediate the association between role stressors and poor sleep and between poor sleep and role stressors.METHODS: We used questionna

Realizing visionary concepts of integrated photonic circuits, nanospectroscopy, and nanosensing will tremendously benefit from dynamically tunable coherent light sources with lateral dimensions on the subwavelength scale. Therefore, we demonstrate an individual nanowire laser based device which can be gradually tuned by reversible length changes of the nanowire such that uniaxial tensile stress is

It has been proposed that the local segregation of kinases and the tyrosine phosphatase CD45 underpins T cell antigen receptor (TCR) triggering, but how such segregation occurs and whether it can initiate signaling is unclear. Using structural and biophysical analysis, we show that the extracellular region of CD45 is rigid and extends beyond the distance spanned by TCR-ligand complexes, implying t

When it comes to religion, lack of conclusive evidence leads many reflective thinkers to embrace agnosticism. However, pure agnosticism does not necessarily have to be the final word; there are other attitudes one might reasonably adopt in a situation of epistemic uncertainty. This article concentrates on J. L. Schellenberg's proposal that non-doxastic propositional faith is available even when be

Is there a political theory in Mary Wollstonecraft’s writings? The question is relevant since Wollstonecraft’s main preoccupation was moral rather than political: the duty of every thinking person to strive to make themselves as good as they can be. This is a complex duty, involving independent thought, acting on principles of reason, and making oneself useful to others. The challenge involved in

Det verkar som att många politiker nästan hyser en outtalad irritation över att det ska vara så svårt för nyanlända att ­lära sig svenska. Men det kan vara mycket svårt att lära sig ett nytt språk, och det måste ibland få ta tid – även för inlärare som ­anstränger sig hårt, skriver Gunlög Josefsson, professor i svenska.

The problem addressed in this paper is a case of word order microvariation in Mainland Scandinavian: optional vs. obligatory Object Shift (OS). Following standard assumptions (see Selkirk 1996), weak object pronouns are assumed to be affixal clitics at PF which do not themselves have the status of prosodic words. Since adverbs (including negation), areunsuitable as hosts, weak object pronouns may
