First human trial shows ‘wonder’ material can be developed safely

A revolutionary nanomaterial with huge potential to tackle multiple global challenges could be developed further without acute risk to human health, research suggests. Carefully controlled inhalation of a specific type of graphene — the world’s thinnest, super strong and super flexible material — has no short-term adverse effects on lung or cardiovascular function, the study…

New non-toxic method for producing high-quality graphene oxide

Researchers from UmeĆ„ have found a new way to synthesize graphene oxide which has significantly fewer defects compared to materials produced by most common method. Similarly good graphene oxide could be synthesized previously only using rather dangerous method involving extremely toxic fuming nitric acid. Graphene oxide is often used to produce graphene by removing oxygen.…

Fresh meat: New biosensor accurately and efficiently determines meat freshness

The freshness of animal meat is an essential property determining its quality and safety. With advanced technology capable of preserving food for extended periods of time, meat can be shipped around the globe and consumed long after an animal dies. As global meat consumption rates increase, so too does the demand for effective measures for…
