Assessing the state of forensic support to criminal investigations in Ghana: A case study in the Greater Accra Region

The study assessed the state of forensic support to criminal investigations by measuring public awareness, knowledge and perception of forensic science in Ghana. A simple random technique was employed to elicit information from 200 consented respondents in selected neighbourhoods in Accra through face to face interviews, questionnaire responses, and random phone calls. The study identified forensic science education as a key challenge among others in the forensic sector. The state of forensics support to criminal investigations in Ghana was rated on the scale of good (10.5%), bad (81.5%) and very bad (8%) indicating that forensic science in Ghana has “gone dark”. The study’s findings call for respective stakeholders and policymakers of Ghana to prioritize forensic support to criminal investigations to promote safety, security, and sustainable economic development

Advances in heterometallic ring-opening (co)polymerisation catalysis

Truly sustainable plastics require renewable feedstocks coupled with efficient production and end-of-life degradation/recycling processes. Some of the most useful degradable materials are aliphatic polyesters, polycarbonates and polyamides, which are often prepared via ring-opening (co)polymerisation (RO(CO)P) using an organometallic catalyst. While there has been extensive research into ligand development, heterometallic cooperativity offers an equally promising yet underexplored strategy to improve catalyst performance, as heterometallic catalysts often exhibit significant activity and selectivity enhancements compared to their homometallic counterparts. This review describes advances in heterometallic RO(CO)P catalyst design, highlighting the overarching structure-activity trends and reactivity patterns to inform future catalyst design
