Visible Light Photolysis at Single Atom Sites in Semiconductor Perovskite Oxides.

Designing catalysts with well-defined active sites with chemical functionality responsive to visible light has significant potential for overcoming scaling relations limiting chemical reactions over heterogeneous catalyst surfaces. Visible light can be leveraged to facilitate the removal of strongly bound species from well-defined single cationic sites (Rh) under mild conditions (323 K) when they are incorporated within a photoactive perovskite oxide (Rh-doped SrTiO). CO, a key intermediate in many chemistries, forms stable geminal dicarbonyl Rh complexes (Rh(CO)), that could act as site blockers or poisons during a catalytic cycle.

Maternal and pregnancy factors contributing to the association between area deprivation and infant mortality in England: a retrospective cohort study.

Background: Socioeconomic inequality in infant mortality in the UK is rising. This study aims to identify contributory maternal and pregnancy factors that can explain the known association between area deprivation and infant mortality.

Methods: A cohort study was conducted using Clinical Practice Research Datalink (CPRD) primary care data between 2004 and 2019 linked to the Index of Multiple Deprivation (IMD), and infant mortality from the Office for National Statistics death data.

Seeing is believing: How front-of-pack food imagery shapes parents' perceptions of child-oriented snack foods.

Child-oriented snack foods often display front-of-pack images suggesting they are natural or wholesome, yet many of these products are ultra-processed and nutrient poor. This study investigated parent's perceptions in response to common forms of front-of-pack food imagery on child-orientated snacks. An online experiment comprising four between-subjects food image conditions (no image; food photo; food cartoon; cartoon of children gardening) and two within-subjects snack type conditions (fruit; vegetable) was conducted with N = 800 Australian adult parents/guardians of children aged 4-10 years.
