#IITGNResearchSnip 1.9: The study diagnoses the potential drivers of hot and cold extremes, which have a negative impact on agriculture in India during monsoon, using observations and linking them to the El Niño–Southern Oscillation phenomenon. Read more. go.nature.com/3fNYGPx

They showed that plasmonic hotspots created at these nanogaps could enhance the fluorescence of a weak emitter by 10,000-folds. They believe that their approach will contribute to push boundaries of single-molecule imaging beyond a few highly fluorescent dyes.

They established nanorod’s surface charge as a key control parameter directing the growth of end-to-end attached gold nanorod assemblies linked via short dithiols (a type of organosulfur compound). The team members include Ashish Kar, Varsha Thambi, and Diptiranjan Paital.

#IITGNResearchSnip 1.19: The study by IITGN researchers reports functional relevance of different oligomeric (made of more than one subunit) states of human THAP9 to help find answers to questions about interaction partners and unknown physiological roles of human THAP9.

The paper presents their observation that the contribution from these correlations near the selected surfaces differ significantly even if there is no solid-fluid attractive interaction. #IITGNResearchSnips

#IITGNResearchCapsule 43: Sourav Mukul Tewari, former MTech student of Mechanical Engineering IIT Gandhinagar, working with Prof Ravi Sastri Ayyagari, has proposed a simple method that uses mapping to create complex shapes (e.g., fork or spring) with embedded defects.

Interestingly, the method also uses a gaming algorithm for this purpose. Handling defects smaller than the size of a single grain is one of its key contributions. The work is published in Computer Methods in Applied Mechanics and Engineering (CMAME). #ResearchersAtIITGN #Metal

#IITGNResearchCapsule 44: Prof Ragavan K, along with Dr Naveen Kumar Endla (a former PhD scholar IIT Gandhinagar), conducted a research study aimed at developing novel designs to improve torque density and efficiency in electrical machines. Link to the paper: bit.ly/3jNDhrI

In machines, tangential force on the rotating part results in output torque. However, a dominant force component is present along radial directions, which doesn't lead to rotatory motion. Recent publications have shown interest in obtaining increased tangential forces in machines

The work uses analytical expressions of 3 different methods of torque estimation and would help designers understand the inherent limitations of cylindrical machines with small space between the stationary & rotating part of the machine in the context of improving torque density.

#IITGNResearchSnip 1.22: The paper presents an extensive overview of different methods of #fabrication, swelling properties, #rheology, and developments in drug delivery applications of #hydrogels. The full paper can be accessed here. bit.ly/3dZ3G22

Hydrogels are water-swollen polymeric materials with a three-dimensional structure and are promising agents for drug-delivery systems.

Dr Prabhakar, who was then Director of Exploration and Excavation in ASI, is now an Associate Professor in Humanities and Social Sciences at IITGN. IIT Gandhinagar has undertaken and completed several projects which have enriched our knowledge about this protohistorical culture.

“The renowned ASI archaeologist, Dr R S Bisht, directed excavations at the site for years. Archaeological Sciences Centre IIT Gandhinagar, through Dr Prabhakar, assisted Dr Bisht in the preparation of Dholavira’s excavation report in 2015,” recounts Prof Michel Danino of IITGN.

“The ASC IIT Gandhinagar conducted an aerial multi-sensor drone survey of Dholavira for the ASI in Dec 2019 and submitted its report a few months later. ASI used some of these imageries in the dossier it submitted to UNESCO.” – Prof Michel Danino, Guest Prof & Coordinator, ASC, IITGN.

#IITGNResearchSnip 1.29: Did you know that sugarcane juice has a role to play in the synthesis of copper oxide (CuO) nanoparticles? The article reports the green synthesis of CuO nanoparticles on a 2D GO matrix using sugarcane juice. Excellent results were observed.

2D graphene-oxide (GO) makes it a more promising material for fabricating CuO hybrid nanostructures with improved properties. The full paper can be accessed here. bit.ly/3DkiEuw #IITGNResearchers #CopperOxide #Nanoparticles #GrapheneOxide #Nanostructures #GreenSynthesis
