News Excerpt:
Researchers at the Institute of Advanced Study in Science and Technology (IASST), an autonomous institute of the Department of Science and Technology (DST), have pioneered a novel method for directly synthesising CNTs on glass substrates at a temperature of 750 °C.
- It could catalyse energy research, biomedical fields, and optoelectronics, rechargeable batteries & flexible electronics.

About the experiment:
- The experiment is performed using the Plasma Enhanced Chemical Vapour Deposition Technique (PECVD), where plasma is generated using a specially designed spiral-shaped fused hollow cathode source.
- This innovative process circumvents the need for elevated temperatures and eliminates the necessity for a transition metal catalyst.
- Furthermore, this synthesis is executed under atmospheric pressure, adding commendable cost-effectiveness to its advantages compared to counterparts in the field.
- Benefits from the experiment:
- Decrease in temperature from conventional CNT (1000 to 750).
- Na as a catalyst is easily removed compared to Fe, Co, and Ni (The challenge of removing these catalysts from CNTs adds a significant cost highlighting the urgent need for cleaner, more sustainable CNT synthesis methods).
