Graphene method could prevent medical implant infections

Researchers in Sweden have developed a method of preventing bacterial infections on medical implants by covering a graphene material with bactericidal molecules. Certain bacteria can form impenetrable biofilms on surgical implants such as dental and other orthopaedic implants. Biofilms are more resistant than other bacteria and infections can be difficult to treat, causing suffering for […]

Interview: NPL’s Dr Andrew Pollard talks graphene

Dr Andrew Pollard, principal research scientist at the National Physical Laboratory (NPL) is helping to pave the way for the commercialisation of graphene. Melissa Bradshaw reports Since its isolation and initial characterisation at Manchester University in 2004, graphene has become something of a hot topic. Classified as an advanced material, the single-atom thick carbon lattice […]

Graphene based material could reduce aircraft noise

A ‘meringue-like’ graphene based material could reduce aircraft engine noise by up to 80 per cent, claim researchers at Bath University. The graphene oxide-polyvinyl alcohol aerogel weighs 2.1kg per cubic metre, which is said to be the lightest sound insulation ever manufactured. The team believes that, when used as insulation within aircraft engines, noise could […]

Graphene sheets form sensor to rapidly detect COVID-19

Researchers at the University of Illinois Chicago have used sheets of graphene to quickly detect COVID-19 in laboratory experiments, an advance that could potentially detect variants of the virus. According to UIC, the researchers combined sheets of graphene with an antibody designed to target the spike protein on the coronavirus. They then measured the atomic-level […]

Imaging technique observes growth of graphene

Researchers have revealed a new method that enables laboratory scanning electron microscopes to observe graphene growing over a microchip surface in real time. This discovery by a team at Surrey University could be a significant step closer to mass commercialisation and production of graphene for electronic devices. Their findings are detailed in ACS Applied Nano […]

Photoresist puts focus on laser-induced graphene

Graphene has been patterned in high-resolution and at the micron-scale with a laser and photoresist, an advance that could lead to applications in consumer electronics. This is the claim of a Rice University laboratory that has demonstrated the conversion of positive photoresist (PR), frequently used in the manufacture of consumer electronics, into laser-induced graphene (LIG). […]

3D printed graphene aerogels set for water treatment

Engineers have developed a new process of 3D printing graphene aerogels that is scalable and stable enough for repeated use in water treatment. The researchers at the University at Buffalo, New York have used a proof-of-concept direct ink writing 3D printing technique and subsequent freeze-drying to prepare graphene-biopolymer aerogels for water treatment. Graphene aerogel sponge […]

Graphene derived from discarded tyres used to strengthen concrete

A process that turns waste from rubber tyres into graphene can be used to strengthen concrete, claim scientists at Rice University in Texas.  According to Rice chemist James Tour, there are clear environmental benefits of adding graphene to concrete. “Concrete is the most-produced material in the world, and simply making it produces as much as […]

Breakthrough 3D printing with inkjet-printed graphene

A new study from Nottingham University has discovered how to use inkjet-printed graphene to 3D-print novel electronic devices with useful properties, such as an ability to convert light into electricity. The £5.85m, EPSRC-funded project was carried out by engineers at the Centre for Additive Manufacturing and physicists at the School of Physics and Astronomy. New […]
