The researchers designed DNA-based nanostructures capable of undergoing controlled structural changes as the surrounding pH changes. Importantly, these changes are reversible, meaning the nanostructures can shift between configurations instead of undergoing a one-time transformation.
Over time, the partnership expanded into satellite development, launch vehicle technologies and Earth observation. Joint missions such as Megha-Tropiques and SARAL became important milestones in cooperation between the Indian Space Research Organisation and France’s space agency CNES.
Researchers from DIT University, IIT Bombay, Bhabha Atomic Research Centre, Ben-Gurion University of the Negev and IIT Kharagpur have demonstrated how the size and oxidation level of graphene oxide nanosheets can determine the patterns formed when tiny droplets of the material dry on a surface.
In order to overcome this difficulty, researchers from the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, an autonomous institute of the Department of Science and Technology (DST) studied four classical blazars – Mrk 421, Mrk 501, PG 1553+113, and PKS 2155-304, that emit very high-energy radiation.
A team of researchers from institutions like the Raman Research Institute (RRI), an autonomous institute of the Department of Science and Technology (DST) and Arizona State University found one way in which the tiny black hole at the centre could energetically influence the ginormous CGM of its host galaxy.
The micro-GPU has been designed as a programmable graphics processor rather than a fixed-function display controller. Its floating-point processing engine allows graphics operations to be performed through hardware that the researchers designed themselves at the RTL level.
An experiment by the Raman Research Institute (RRI), an autonomous institute of the Department of Science and Technology (DST) has now measured the quantum measure assigned to a chosen collection of possible photon paths between the laser source and the detector.
Dilution refrigerators are highly specialised cooling systems capable of reaching temperatures only a fraction of a degree above absolute zero. Such temperatures are essential for several types of quantum processors, particularly superconducting quantum computers whose qubits must operate in an environment with extremely low thermal noise.
The researchers selected two substantially different bacterial species for the experiments: Staphylococcus aureus, which is Gram-positive, and Pseudomonas aeruginosa, which is Gram-negative. Their different cell-envelope structures allowed scientists to investigate whether the preservatives could act effectively against fundamentally different types of bacteria.
More importantly, the two agencies have broadened the areas covered by the arrangement. Existing cooperation in Earth observation, satellite navigation, space science and mission operations will continue, while human space exploration, robotic exploration and space weather have now been explicitly incorporated.
