Novel, Scalable, Sustainable Graphene Synthesis
Over the summer of 2024, I had the honor of working with Dr. A.S. Khanna (retd. IIT Bombay) on learning how to use electrolytic exfoliation to synthesize graphene in the lab.
Abstract:
Graphene is a novel nanomaterial, only recently discovered in 2004. It has prompted multiple scientific
breakthroughs in a variety of fields, proving transform industries at a large scale, such as electric vehicles,
batteries, solar panels, protective coatings, etc. Historical methods of graphene synthesis, including
mechanical and chemical exfoliation and chemical vapor deposition (CVD), present challenges such as high
costs and are also environmentally unfriendly, posing sustainability concerns.
Understanding graphene manufacturing through a sustainable lens is extremely important for graphene’s longevity.
This study aims to explore the optimal conditions for electrolytic exfoliation, a sustainable, scalable, and simple method for graphene production, by determining the optimum electrical current to maximize both quantity and quality of graphene yield, verified through qualitative observations and subsequent analysis using Raman Spectroscopy and SEM/EDX.
Results indicated that an electrical current of 0.2–0.3A yielded the most substantial and high-quality graphene. This research highlights the potential for optimizing the electrolytic exfoliation process to produce graphene sustainably and efficiently, showing promise for widespread industrial application and further research into refining these methods for cleaner,
sustainable and more effective graphene production.
Innovative Testing Method: Checking Efficacy of Paint Coatings
I love tinkering and playing around with objects and things - my friends tell me ‘experimenter’ is my middle name. In the summer of 2023, I worked with ElectroLab, a pharma lab equipment manufacturer, helping them devise a method to test paint corrosiveness.
Abstract:
Electrolab India, an established manufacturer of pharmaceutical testing equipment, encountered a significant challenge with corrosion in its dissolution testers, primarily caused by the highly acidic environment required for dissolution testing.
This study aimed to find novel alternatives to address the limitations of traditional corrosion resistance tests (industrial standards), such as the ISO 9227 salt spray test, which failed to accurately simulate the conditions inside a dissolution tester due to the neutral pH of the 𝑁𝑎𝐶𝑙 solution used. In overcoming this, a novel testing system was designed, developed, and tested with the objective of successfully evaluating the efficacy of protective coatings
against corrosion.
The system used hydrochloric acid (𝐻𝐶𝑙) fumes, better mimicking acidic conditions dissolution testers are usually exposed to. The custom setup involved an innovative design, incorporating a closed system with rotating or oscillating capabilities to emulate fluid motion and account for hydrodynamics while ensuring the use of non-corrosive materials in the apparatus itself.
Experimental verification showed that samples exposed to 𝐻𝐶𝑙 exhibited higher corrosion
rates than those in 𝑁𝑎𝐶𝑙, confirming that 𝐻𝐶𝑙 is a superior discriminatory agent. The results indicate that the new testing system is a more effective and unbiased tool for assessing the durability of coatings, offering Electrolab a reliable means to enhance its product lifespan and quality.
