Biodegradable Supercapacitor Blog Image

Overview:

Recently, scientists at Gujarat Energy Research and Management Institute (GERMI) have developed the thinnest, lightweight and biodegradable paper-based supercapacitor.

About Biodegradable Supercapacitor:

  • A supercapacitor is an electrochemical charge storage device with a fast charging/discharging cycle, high power density and a longer lifecycle. 
  • Features
    • This supercapacitor which can fully charge a device within 10 seconds, has been developed from seaweed (marine macroalgae).
    • The device is of high tensile strength and performance, as well as cost-effective, according to the researchers.
    • The product can be used in electronics, memory backup systems, airbags, heavy machines, electric vehicles, etc.; hence, it holds a huge business prospect. 

What is Seaweed?

  • Seaweeds are macroalgae attached to rock or other substrata and are found in coastal areas.
  • They are classified as Chlorophyta (green), Rhodophyta (red) and Phaeophyta (brown) based on their pigmentation.
  • Among them, Chlorophyta holds more potential components like carbohydrates, lipids, proteins and bioactive compounds in the cell wall.
  • Green seaweed has a high amount of a particular type of cellulose in its cell wall.

 


Q1) What is Algae?

Algae are a diverse group of photosynthetic organisms that are found in aquatic environments such as oceans, lakes, rivers, and ponds. They can also exist in moist terrestrial habitats like rocks, soil, or even on the surface of trees. Algae are not classified as plants but are considered simple, plant-like organisms.

Recently, the Titan, the vessel that went missing in the area of the Titanic wreck in the North Atlantic.

About Titanic Tourist Submersible:

  • What it is? A submersible is a small boat or other craft, designed especially for research and exploration.
  • It is more limited in its movement and how long it can stay underwater.
  • A submersible needs a mother ship that can launch and recover it.
  • These are small, limited-range watercrafts designed for a set mission, that are built with characteristics that allow them to operate in a specific environment
  • These vessels are typically able to be fully submerged in water and cruise using their own power supply and air renewal system.
  • While some submersibles are remotely operated and essentially manually controlled or programmed robots, these usually operate unmanned.
  • Vessels like the missing Titan are known as human-occupied vehicles.

What is a submarine?

  • It is a watercraft that is capable of independent operation under the sea.
  • It does not require support ships because submarines can renew their air and power supplies independently.
  • When the submarine is to dive water is filled in water tanks and it is made heavier.
  • As soon as the average density of a submarine becomes greater than the density of seawater it sinks.

 


Q1) What is Exploration?

Exploration refers to the act of discovering, investigating, or venturing into new territories, areas, or realms. It involves the systematic search or study of unfamiliar or unknown environments, whether physical, intellectual, or conceptual, in order to gain knowledge, understanding, or practical benefits.
