Piezoresponsive Nanomaterials (PN)
Indian researchers have developed peptide (a short chain of amino acids)-based adjustable piezoresponsive nanomaterials that can help in energy harvesting and biodevice applications.
Piezoresponsive Nanomaterials (PN)
- PN can change their physical properties, like electrical resistance, when subjected to mechanical stress.
- This unique ability helps to generate an electric charge when subjected to pressure.
- Due to this ability, these materials are typically used in applications like sensors, actuators, and energy harvesting devices.
- When they are composed of nanostructured materials, it enhances their sensitivity and responsiveness to external forces.

Phytoplankton bloom
Recently, scientists found evidence that desertification leads to large amounts of nutrient-rich dust landing in the Indian-Ocean, south east of Madagascar, causing phytoplankton (Algae) bloom.
Phytoplanktons:
- Microscopic, single-celled plants that live in the ocean.
- They regulate the carbon sink and food chain (primary producers) in the ocean.
About Phytoplankton bloom:
- It’s the exponential growth of phytoplankton.
- Favorable conditions: Warm Sea surface temperature, calm waters, availability of excessive nutrients etc.
- Impact: Produce biotoxins that can bioaccumulate in the marine food web; depletes the oxygen level in the ocean creating ‘Dead Zone’.
