Nanosheet-stabilised Emulsions: A Route Towards Single-droplet Devices

Our work on nanosheet-stabilised emulsions demonstrates that 2D materials (including graphene and molybdenum disulfide) confer emulsion stability and network conductivity at volume fractions as low as 10⁻⁵. Emulsions can be deposited as inks for functional thin films which preserve droplet structure and eliminate the notorious coffee ring effect, highlighting the potential for printed single-droplet devices.

NOAir Quality Sensor

Did you know that nitrogen dioxide (NO2) levels in Brighton are among the highest in the UK? NO2 is an air pollutant that originates from combustion engines and industrial processes. Long-term exposure to NO2 can cause respiratory issues, which can be particularly severe and even life-threatening for babies and asthma sufferers. We have developed a laser deposited carbon aerogel gas sensor with exceptional selectivity towards NO2.

Flexible Touchscreen Technology

Using a combination of graphene and silver nanowires we have developed an optically transparent, flexible touchscreen technology, eliminating the need for glass smartphone screens. Current touchscreen technology requires rare-earth alloys which are extracted by mining, making them unsustainable and expensive. This graphene technology would significantly reduce the cost of smartphone screens while improving their durability and flexibility.

Fighting Cot Death: graphene-enabled breathing monitors 

We have developed highly sensitive breathing monitors out of a simple mixture of oil, water and graphene. These are a cheap, non-intrusive alternative to the current technology, with potential to alert parents of any change to their child’s breathing via their smartphone, potentially preventing seizures and cot death, which sadly affect hundreds of families each year.
