Catalytic Pyrolysis of Polyethylene with Microporous and Mesoporous Materials: Assessing Performance and Mechanistic Understanding.

Testing the catalytic performance for the catalytic pyrolysis of plastic waste is hampered by mass transfer limitations induced by a size mismatch between the catalyst's pores and the bulky polymer molecules. To investigate this aspect, the catalytic behaviour of a series of microporous and mesoporous materials was assessed in the catalytic pyrolysis of polyethylene (PE). More specifically, a mesoporous material, namely sulfated zirconia (Zr(SO)) on SBA-15, was synthesized to increase the pore accessibility, which reduces mass transfer limitations and thereby enables to better assess the effect of active site density on catalyst activity.

Politicians' high-status signals make less-educated citizens more supportive of aggression against government: A video-vignette survey experiment.

Various branches of the literature suggest that exposure to the high-status appearances and lifestyles of politicians in contemporary "diploma democracies" affects the attitudes and behavior of less-educated citizens because it confronts them with their lower status in the political domain. Informed by this, we theorize that such exposure inspires docility (a lower subjective social status, weaker feelings of political entitlement) and revolt (anger, more support for aggression against government). To investigate this, we conducted an original, pre-registered, video-vignette survey experiment among a representative sample of the Dutch population.

Sugar tax and product reformulation proposals reduce the perceived legitimacy of health-promotion institutions: a randomized population-based survey experiment.

Background: Structural nutrition interventions like a sugar tax or a product reformulation are strongly supported among the public health community but may cause a considerable backlash (e.g. inspiring aversion to institutions initiating the interventions among citizens).

What do stances on immigrants' welfare entitlement mean? Evidence from a correlational class analysis.

Recent in-depth qualitative research indicates that different people ascribe different meanings to their apparently similar stances on immigrants' entitlement to welfare. We are the first to investigate such variation quantitatively among the public-at-large, applying the novel method Correlational Class Analysis to an original survey fielded among a representative sample in the Netherlands (n = 2138). We uncover five ways of looking at immigrants' entitlement to welfare, each including both people who oppose that entitlement and those who support it.

High-rate pacing suppresses Torsade de Pointes arrhythmias and reduces spatial dispersion of repolarization in the chronic AV-block dog model.

An electrical storm of Torsade de Pointes arrhythmias (TdP) can be reproducibly induced in the anesthetized chronic AV-block (CAVB) dog by infusion of the I-blocker dofetilide. Earlier studies showed that these arrhythmias 1) arise from locations with high spatial dispersion in repolarization (SDR) and 2) can be suppressed by high-rate pacing. We examined whether suppression of TdP by high-rate pacing is established through a decrease in SDR in the CAVB dog.
