Scientists Create Temperature-Tunable Nanomaterials

In April 2026, researchers from the Centre for Nano and Soft Matter Sciences (CeNS) and the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) developed a novel method to control nanomaterial properties using temperature, enabling adaptive electronic applications.

Key Points

Breakthrough Innovation:
- Temperature used as a switch to control structural, optical, and electrical properties.
- Enables development of smart and adaptive materials.
Material Used:
- Naphthalene diimide (NDI), an amphiphilic organic molecule.
- Forms nanostructures through supramolecular self-assembly.
Structural Transformation:
- At room temperature: forms circular nanodisks.
- On heating: transforms into two-dimensional nanosheets.
Optical Properties:
- Nanodisks exhibit chiroptical activity (interaction with polarized light).
- Nanosheets lose chiroptical properties.
Electrical Properties:
- Nanodisks show higher electrical conductivity.
- Conductivity drops nearly sevenfold after transformation.
Scientific Significance:
- Demonstrates precise tuning of material properties.
