Next Generation Mixed Metal Transition Metal Non-Oxide Supercapacitors

This approach stands out through its robust handling of peripapillary atrophy and vascular shadows using inverse-intensity weighting, while integrating gradient orientation and intensity terms to refine contours. By combining enface and 3D layer information, it achieves accurate, smooth boundaries for both disc and cup. The energy-minimizing active contour and PDM-based classification ensure automated, reproducible segmentation and diagnosis, offering clinicians precise, quantitative metrics for early glaucoma detection and progression monitoring.

Description

A novel hydrazide sol-gel (HSG) process involving the reaction of metal alkoxides with hydrazine was developed by the investigator for synthesizing HSA (~250 m2/g) nanostructured binary TMNs. The versatile approach can generate multi-component TMNs, providing an ideal test bed for studying the role of structure, composition, and microstructure on the electrochemical response of supercapacitors.
