Rice University Develops Gas Sensors from Laser-Induced Graphene

Graphene is a form of carbon valued for its unique material properties including high charge mobility, mechanical strength, and thermal conductivity. Since laser-induced graphene (LIG) was discovered at Rice University, laser technology has received considerable attention as a simple way to synthesize porous graphene. Through ongoing research, the numerous practical applications for LIG continue to expand, from water treatment to supercapacitors and wearable body-condition sensors. Most recently, the research team at Rice University published an article in ACS Nano describing the efficacy of LIG as a gas-sensing material. The team created flexible graphene gas sensors which were able to determine the composition of various gas mixtures through thermal conductivity. They were also able to incorporate these sensors into a cement composite, representing a big step towards “smart” construction materials and the overall adoption of carbon-based electronics.

Universal Laser Systems® New ULTRA 9 Platform Enables Advanced Material Processing

Scottsdale, AZ – February 21, 2019 – With the increasing use of advanced materials in industrial applications from aerospace to medical devices, comes a growing need for innovation in material conversion technology. Developments in laser processing aim to overcome the limitations of existing technology and push the boundaries of how materials can be used. To this end, Universal Laser Systems has released a platform with unprecedented material processing capabilities.

The new ULTRA 9 platform is designed to perform laser cutting, laser ablation, and laser surface modification. When configured with patented MultiWave Hybrid™ technology, it can combine the laser energy of up to three wavelengths – 9.3 µm (CO2), 10.6 µm (CO2), and 1.06 µm (fiber) – by independently controlling each spectral component of the beam. The user is able to select the ideal wavelength or combination of wavelengths based on the material, allowing for maximum process flexibility.
