Imperfect graphene opens door to better fuel cells

The honeycomb structure of pristine graphene is beautiful, but Northwestern University scientists, together with collaborators from five other institutions, have discovered that if the graphene naturally has a few tiny holes ...

Thinnest feasible nano-membrane produced

A new nano-membrane made out of the 'super material' graphene is extremely light and breathable. Not only can this open the door to a new generation of functional waterproof clothing, but also to ultra-rapid filtration. The ...

Direct 'writing' of artificial cell membranes on graphene

Graphene emerges as a versatile new surface to assemble model cell membranes mimicking those in the human body, with potential for applications in sensors for understanding biological processes, disease detection and drug ...

Laying down a discerning membrane

One of the thinnest membranes ever made is also highly discriminating when it comes to the molecules going through it. Engineers at the University of South Carolina have constructed a graphene oxide membrane less than 2 nanometers ...

Jagged graphene edges can slice into cell membranes

(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt ...

New system to improve DNA sequencing

(Phys.org) —A sensing system developed at Cambridge is being commercialised in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, and individualised ...
