Enzyme Mimetic to Degrade Pollutants in Waste-Water

Recently, Scientists at Indian Institute of Science (IISc) Materials Research Centre developed a sunlight-driven enzyme mimetic for wastewater treatment.

  • The study introduced a platinum-containing nanozyme called NanoPtA.
  • NanoPtA forms tape-like structures when in contact with wastewater and emits light to degrade pollutants.
  • It can degrade common effluents in ten minutes under sunlight and remains stable for up to 75 days.
  • Nanozyme may find applications in healthcare, particularly for neurological diseases.
    • Natural enzymes face limitations like sensitivity, complex production, and storage issues.
    • Nanozymes can overcome these challenges and mimic natural enzymes.

Using Gravity to Solve Power’s Problem

Gravity-based energy storage is emerging as a solution to renewable energy intermittency and interruption, with the help of Energy Vault, which is in talks with Indian companies like NTPC, Tata Power, and ReNew Power.

  • Energy Vault offers the EVx platform using gravity and mechanical elevators to store and release energy with 25-tonne blocks.
  • It also focuses on short-term storage, eco-friendly materials, and green hydrogen energy storage.
    • India's push for renewable power makes energy storage crucial as its renewable energy growth presents challenges for grid managers.
  • Most energy storage worldwide comes from pumped hydro, but alternative solutions are being explored.
    • The Indian government is considering hydrogen and hybrid generation models for energy storage.
    • Efforts are being made to identify pumped hydro sites, including potential use of opencast mines.

15-Minutes Cities and the Conspiracy Theories

Recently, Conspiracy theories have emerged online, falsely depicting 15-Minute Cities as a dystopian plot to restrict people's movement and conspiracy theorists have associated 15-minute cities with totalitarian agendas and international organizations like the World Economic Forum.

  • The term "15-minute cities" was coined by Carlos Moreno in 2016 to reimagine urban planning for convenient access to essential services.
  • The concept of 15-minute cities aims to ensure that essential services are within a short walk or bike ride from one's home.
    • Low-traffic neighborhoods (LTNs) are often linked to 15-minute cities and are seen by conspiracy theorists as part of a broader "war on drivers."
