Researchers at Raman Research Institute, Bengaluru, are exploring the properties of single walled carbon nanotube (CNT) immersed in aqueous triblock copolymer solution. The newly formed CNT-polymer hybrid could replace the use of carbon nanotubes by itself, thanks to its remarkable mechanical, thermal and electrical properties.
What is dark matter? Where and how does it exist? These are some of the questions scientists from the Raman Research Institute and Indian Institute of Science, Bangalore, have attempted to answer in their recent paper.
LMC X-4 is a two-star system consisting of a pulsar and a companion star. In a recent study, scientists from the Raman Research Institute, Bangalore, examined characteristics of the X-ray signals emitted from LMC X-4, using signal processing techniques and analysis.
Researchers from the Indian Institute of Science (IISc), Indian Institute of Technology Bombay (IITB) and the Raman Research Institute (RRI) have investigate how materials undergo such deformations, and how they can be controlled to manufacture materials with the desired properties.
C V Vishweshwara or “Vishu” as he was known to all, was born on 6th March 1938, in Karnataka. He finished most of his schooling in Bengaluru and then his graduation in Mysore University. For his PhD, he moved to Columbia University and later to University of Maryland in USA, to work on general relativity. On returning to India, Vishu joined Raman Research Institute in Bengaluru and then later joined the Indian Institute of Astrophysics.
How do stars and star clusters influence their neighbourhood? How does the birth of stars affect their neighbours? let us start with the birth of a star. It begins with gasses, mostly hydrogen, accumulating under gravity until it gets hot and dense enough to start nuclear fusion, where the lighter Hydrogen atoms merge to form heavier helium atoms, with an enormous outburst of energy. This energy moves in the form of a shockwave, pushing all the excess gas away from the newborn star. For a million years after its birth, high energy radiation from the star continues to push the surrounding gas away. From here the picture gets a little murky as we hadn’t quite understood what happened around a star or a cluster of stars, after the million year mark. Now a new study by researchers from Raman Research Institute (RRI), the Indian Institute of Science (IISc) and P.N Lebedev Physical Institute, Moscow, Russia could throw more light on this issue. They have successfully developed a model to simulate the interaction of a star cluster with its surroundings. The model was then tested for accuracy by comparing it with observations from Tarantula Nebula, a nearby star cluster, where the observations matched closely to the predictions made by the model. Maybe now we can better understand the processes that guide the formation of stars, nebulae and galaxies!
