HYDERACENE

HYDERACENE Latest News

The University of Hyderabad (UoH) recently secured an Indian patent for HYDERACENE, a dual-action material designed specifically for rocket propellants and high-performance defence applications.

About HYDERACENE

It is a novel polymer-based material developed for use in solid rocket propellants for defence and space applications.
The innovation was developed by Mutyalanaidu Ganivada, Sourav Jana, and Tushar Jana of the School of Chemistry, with the University of Hyderabad as the patentee.
The patented material, formally described as Ferrocene Polyethylene Glycidyl Grafted Hydroxyl-Terminated Polybutadiene, was synthesised using ring-opening polymerisation.
Why is this Innovation Significant?
- In conventional solid rocket propellants, two critical components are required:
  - The Binder: A glue-like polymer that holds all active fuel components together while providing structural integrity.
  - The Catalyst: A specialized chemical additive that speeds up and controls the burning rate of the propellant.
- Traditionally, these are two separate materials. HYDERACENE acts as both at the same time—a polymer binder-cum-catalyst.
- This improves long-term stability by preventing the catalyst from separating from the binder over time and enables more controlled and efficient combustion in solid rocket motors.
- Hyderacene has also been developed as an indigenous alternative to Butacene, a commercially used material in aerospace and defence applications.
  - BUTACENE is largely imported from European countries.
Named after the city of Hyderabad, the patented material is designed for use in high-performance rocket propellants and other advanced defence applications requiring controlled burn rates and improved propulsion efficiency.

Introducing the hexavalent (six-in-one) vaccine into India’s Universal Immunisation Programme (UIP) could improve the efficiency of the country’s childhood immunisation programme, according to a recent study conducted by the Union Health Ministry.

About Hexavalent Vaccine

It is a combination vaccine that protects infants against six different diseases with a single injection.
It combines six different antigens through special manufacturing processes.
The hexavalent vaccine protects against:
- Diphtheria
- Tetanus
- Pertussis (Whooping Cough)
- Hepatitis B
- Polio
- Haemophilus influenzae type b (Hib) infections
Hexavalent vaccine could deliver several benefits, including:
- Fewer injections for infants, making vaccination more convenient for children and caregivers.
- Lower cold-chain storage requirements.
- Reduced use of syringes and other vaccination supplies.
- Less time spent by Auxiliary Nurse Midwives (ANMs) administering vaccines and maintaining records.
- Lower workload for cold-chain handlers and vaccine managers.
- Time savings for parents and caregivers during immunisation visits.

Hippocampus amandavincentae Latest News

Scientific studies recently identified a new species of seahorse named Hippocampus amandavincentae, which was previously misidentified as Hippocampus histrix.

About Hippocampus amandavincentae

It is a new species of seahorse.
It was recorded off the southwest coast of Kerala.
This discovery has made a total of 5 seahorse species discovered from the Kerala coast.

What is a Seahorse?

A seahorse is a marine fish belonging to the genus Hippocampus and related to pipefishes.
There are at least 50 species of seahorses.
Distribution: They are found in temperate and tropical waters around the world.
Habitat:
- Typically found in shallow waters with abundant vegetation such as coral reefs, mangroves, seagrass beds, and estuaries.
- They are usually found clinging to plants or corals with their tails.
They are unique in appearance, with their horselike head, prehensile tail, independently moving eyes, and brood pouch.
They have long, tubular snouts and small, toothless mouths.
Their bodies are covered with consecutive rings of bony plates.
Seahorses vary in size, ranging in length from about 2 to 35 cm.
Seahorses are rather immobile, swimming more slowly than other fishes.
When swimming they maintain a vertical position and propel themselves forward using a soft-rayed dorsal fin. They use pectoral fins located on the side of the head to maneuver.
To move up and down, they adjust the volume of air in a tiny pocket inside their body, called a ‘swim bladder’.
Experts in camouflage, they can change color to blend into their surroundings and avoid danger.
They are carnivores. They eat small crustaceans and invertebrates.
