The 2023 Nobel Prize in Chemistry has been awarded to Maungi Bawendi, Louis Bruce, Alexey Ekimov. All three are American-born chemists. He has received this honor for the discovery and development of quantum dots. Quantum dots are nanoparticles that are so small that their size determines their properties.
Quantum dots are used today to illuminate computer monitors, mobile phones, and television screens. QLED technology is used in it. The light of quantum dots is so bright that when it is shone on the tumor, surgeons will have no problem in seeing the tissue.
Quantum dots will be helpful in making flexible electronics
Quantum dots add particles to the light of many LED lamps that make precise work easier.
Researchers have also used quantum dots to create colored light. The Nobel Prize-winning chemists believe that in the future, quantum dots could contribute to flexible electronics, tiny sensors, thin solar cells and perhaps encrypted quantum communication.
Polonium was present in the atomic bomb dropped on Nagasaki, the scientist who discovered it received the Nobel Prize.
Poland-born physicist and chemist Marie Curie, along with her husband Pierre Curie, made many scientific discoveries. Discovery of two new elements, radium and polonium, was announced in 1898. It was a difficult task for Mary to separate pure samples of these elements. It took four years to extract 1 decigram of radium chloride from several tons of raw ore.
In 1911, Curie received her second Nobel Prize in Chemistry for her discovery of radium and polonium. A few years after Marie Curie was honored, America dropped atomic bombs on two Japanese cities. Polonium was also a main element of the detonator of the bomb that was dropped on Nagasaki. Although Curie was not involved in the project of making the atomic bomb.
Venkatraman Ramakrishnan of Indian origin received the Chemistry Nobel Prize.
Venkatraman Ramakrishnan, one of the most distinguished scientists of Indian origin, received the 2009 Nobel Prize in Chemistry in the field of Molecular Biology. In 2000, he mapped the structure of the ribosome, made up of hundreds of thousands of atoms, using a method called X-ray crystallography. This helped a lot in making antibiotics.
Large and complex protein molecules manage all the functions of the body of any organism. These are made in the ribosomes of the cell. Their genetic information is translated into amino acid chains through RNA. This then makes proteins. Using this theory, he created the structure of the ribosome through X-ray crystallography.
Venkatraman was born in 1952 in Chidambaram, Tamil Nadu. He studied science in America and Britain. Apart from the Nobel Prize, Venkatraman was also awarded the Padma Vibhushan in 2010. He was selected for a knighthood in the 2012 New Years Honors List.
The chemist who made lithium battery was the oldest winner of Nobel Prize.
The oldest Nobel laureate to date is John B. Good enough. Goodenough was 97 years old when he was awarded the Nobel Prize in Chemistry in 2019. He was also the oldest winner to be honored in any Nobel Prize field.
In 1980 John Goodenough developed a lithium battery with a cathode of cobalt oxide. Lithium ions can be placed at the molecular level in the cathode of cobalt oxide. This cathode gave higher voltage than earlier batteries. Goodenough’s contributions were important in the development of the lithium-ion battery. Today it is used in everything from mobile phones to electric cars.
