‘Forensic fingers’ for crime scene investigation

A team of scientists in the United States has developed a wearable fingertip sensor to enable crime scene investigators to rapidly detect explosives and gunshot residue. Traditional forensic analysis is typically carried out in a central laboratory, which requires time-consuming processes s ... more

High-performance epoxy resin adhesives from renewable green starting materials

A series of epoxy resins has been synthesised by a team of chemists from Germany, who used renewable starting materials for a more environmentally friendly approach than conventional methods. The resulting epoxy resins have highly desirable mechanical properties, such as high stiffness, tha ... more

Electrospun polymer fibres better than non-woven polymer fibres at mopping up oil from oil spills

Electrospun polystyrene shell/polyurethane core fibres made by scientists in China have absorption capacities 2-3 times higher than reported for non-woven polypropylene fibres (widely used to clean up oil spills). Electrospun fibres are an ideal candidate for soaking up oil, as their struct ... more
