Depolymerisation of poly(lactide) under continuous flow conditions.

Poly(l-lactic acid) (PLLA) is commercially successful bio-based plastic, where end-of-life materials can undergo industrial composting. To create a circular economy, a desirable alternative to composting is chemical recycling to monomer (CRM), where direct depolymerisation to l-lactide can be achieved. CRM of PLLA is typically impeded by thermal decomposition and side reactions, due to the high ceiling temperate ( ) of PLLA in bulk (>600 °C), which preclude implementation on a large scale, and has led to the development of catalytic strategies, under vacuum or high dilution in high boiling point solvents conditions.

The mental health trajectories of male prisoners and their female (ex-)partners from pre- to post-release.

Background: There are high rates of mental disorders among prisoners. Prisoners are also likely to have difficulties with intimate relationships, perhaps related to the imprisonment, but their mental health may be relevant. There is a dearth of research on intimate relationship qualities and mental health of offenders and their partners over time.

The destructive capacity of drug abuse: an overview exploring the harmful potential of drug abuse both to the individual and to society.

From a public health perspective, substance abuse has long been a source of major concern, both for the individual's health and for wider society as a whole. The UK has the highest rates of recorded illegal drug misuse in the western world. In particular, it has comparatively high rates of heroin and crack cocaine use.
