MXene-enabled textile-based energy grid utilizing wireless charging
Background - Powering e-textiles requires an on-garment energy grid
Project - To develop an on-garment induction charging system
Result - We developed an on-garment induction coil by directly printing it onto textiles. We demonstrated the validity by powering microcontrollers and a wire-free joule heating element. This work led to a patent application through the Accenture Labs Future Technology Group.

Shear delamination of multilayer MXene
Background - Typically the processing of MXene nanomaterials is done with hazardous chemical intercalants limiting the processability and contributing to hazardous waste
Project - Use high-shear methods to process MXenes
Result - Multiple types of MXenes were processed with high shear methods and the material produced had superior electrochemical energy storage properties when compared to traditionally processed materials.
Skills - High shear processing, electrochemistry, XRD, SEM
High-yield and high-throughput delamination of multilayer MXene with high-pressure homogenization
Background - The large-scale production of MXene is slow, has low yield, and produces excessive waste
Project - Utilize high-energy methods for the delamination of MXene
Result - We improved yield by 60%, throughput by ~10X, and reduced hazardous waste to zero, all while expanding the application space and maintaining material properties, leading to a process patent application
Skills - High-energy processing, electrochemical analysis, SEM, XRD, Raman, UV-Vis
