1. Inspiring colours

Syllabus: Developments in Science and Technology

Mains: Quantum dots revolutionize the semiconductor industry

Prelims: Quantum dots

Context:​ The 2023 Nobel Prize in Chemistry has been awarded to a trio of scientists for their groundbreaking work in the field of quantum dots, often referred to as “artificial atoms.”

  • Quantum dots, despite their complex quantum mechanical properties, have practical applications and are inspired by the vibrant colours observed in stained glass. 
  • This recognition highlights the significance of their work and the artistic inspiration behind their creation.

Understanding Quantum Dots:

  • Quantum dots are minuscule crystals, a few nanometers wide, known as “artificial atoms.”
  • Unlike atoms, their behaviour is influenced by packing density; when closely packed, they exhibit unique properties.
  • Each quantum dot has only a few thousand atoms (whereas a single droplet of water can have a sextillion). And because the atoms are packed so closely together in the dot, their electrons are very close to each other.
  • Quantum dots contain only a few thousand atoms but can mimic the behaviour of individual atoms due to their densely packed structure.
  • One remarkable property is their response to light: they absorb and re-emit light at different frequencies depending on their size, with smaller dots emitting bluer light.

Significance of Quantum Dots

Quantum dots have found diverse applications in various fields, including:

  • Electronics: Used in transistors to enhance device performance.
  • Lasers: Employed to create highly efficient lasers.
  • Medical Imaging: Applied for precise medical imaging, aiding in diagnoses.
  • Quantum Computing: Utilized in quantum computing technologies, promising significant advancements.

The Nobel Prize Laureates

  • Alexei Ekimov (1981): First synthesized quantum dots ‘frozen’ inside glass.
  • Louis Brus (1983): Synthesized quantum dots in a solution and explored their quantum-physical properties.
  • Moungi Bawendi (1993): Developed a reliable method to produce high-quality quantum dots.

Nut Graf: The Chemistry Nobel Prize awarded to the pioneers of quantum dots acknowledges the transformative impact of their work on both scientific research and practical applications. These artificial atoms, inspired by the beauty of colours in stained glass, have opened doors to technological advancements in electronics, lasers, medical imaging, and quantum computing. Quantum dots remind us that the convergence of art and science can yield remarkable discoveries and inspire further exploration into the mysteries of the universe.

F. Prelims Facts

1. Bangladesh gets its first batch of uranium

Syllabus: GS 2- International Relations

Prelims: Current events of national and international importance.

Introduction

  • Bangladesh has received its first delivery of uranium for the Russian-backed nuclear plant project.
  • The project aims to strengthen Bangladesh’s energy grid but faces complications due to sanctions on Moscow.

Russian Support and Financing

  • Russia is providing significant support to Bangladesh for the nuclear plant project, with a loan covering 90% of its total cost, amounting to $12.65 billion.
  • The project is expected to help alleviate chronic power shortages in Bangladesh.

Russian President Vladimir Putin’s Statement

  • During a videoconference with Prime Minister Sheikh Hasina, Russian President Vladimir Putin emphasised the long-term friendship and partnership between Russia and Bangladesh.
  • Putin also pledged assistance in the supply of uranium, maintenance, and management of spent fuel for the nuclear plant.

Nuclear Plant Project Details

  • The nuclear plant is located in Rooppur, a village along the Ganges River, approximately 175 km west of the capital city, Dhaka.
  • Construction on the plant began in 2017, with the first of its twin 1,200-megawatt units scheduled to commence operations in the coming year.
  • Both reactors are expected to be fully operational by 2025.
