• Talga graphite used to make higher performing graphene-based sensor suitable for widespread environmental, healthcare and automotive applications
• Sensor showed a 10 fold increase in sensitivity over other materials
Advanced materials company Talga Resources Ltd (ASX:TLG) ("Talga" or "the Company") is pleased to advise that a collaborative scientific study undertaken by the Indian Institute of Technology and Talga (using Talga materials in a sensor application) has been published in the Royal Society of Chemistry Advances journal1.
The study used Talga's 99.7% purity graphite to construct a graphene sensorfor detection of NO2 inthe form of nitrites, a widespread chemical of the natural and industrial world and major component of air and water pollution.
Thegraphene successfully improved the sensor's sensitivity to NO2 which was measured to be 10x that of competing sensor materials. In addition, the use of graphene enabled a simpler more eco-friendly production process and lowered the amount of expensive active ingredients.
Applications and Markets
Sensors to detect nitrite compounds have widespread applications that include:
The drivers for sensor applications are increasing demands for better environmental health, better resource utilisation and lower pollution.
Talga Managing Director Mark Thompson commented: "The published results support that Talga's base products can be used in multiple applications and indicates new demand possibilities for Talga graphite and graphene materials in the multi-billion dollar global sensor market. As we are focusing on larger volume applications in our products strategy we will seek partners to advance our materials in this sector."
