SUMMARY:[Seminar]: Listening to Light: Transforming Treatment through Photoacoustic Imaging
DESCRIPTION:Speaker: Dr. Sanhita Sinharay\, Assistant Professor\, Department of Bioengineering\, IISc.\n\nTitle: "Listening to Light: Transforming Treatment through Photoacoustic Imaging"\n\nDate: Thursday\, October 09\, 2025 - Time: 4 PM\n\nHi-Tea & Coffee: 5 PM\n\nVenue: CeNSE Seminar Hall \n\n\nAbstract:\nNoninvasive imaging methods can quantify changes in biological/physiological signatures \nwithout need for invasive biopsies in real-time and within the entire tissue of interest. \nPhotoacoustic or optoacoustic imaging is a relatively new hybrid imaging modality that \ncombines the rich optical contrast with high resolution of ultrasound and can be used to \nimage specific tissue biomarkers at tissue depth of >3-5 cm. Currently\, with its FDA approval \nfor breast cancer patients\, this imaging modality demonstrates rich potential for clinical \ntranslation in other scenarios. I will focus on how our laboratory is using this modality to \nlongitudinally monitor treatment outcomes and the development of a new class of theranostic agents\, \nwhere the diagnostic modality is photoacoustic imaging.\n\nBiography:\nSanhita completed her B.Sc. and M.Sc. degrees in Chemistry from Jadavpur University and IIT Madras\, \nrespectively. She received her Ph.D. from the University of Arizona\, AZ\, USA\, in the Department \nof Chemistry and Biochemistry\, where she designed and translated Chemical Exchange Saturation \nTransfer (CEST) MRI contrast agents for the detection of in vivo enzyme activity within mice \ntumor models. As a post-doctoral fellow at the National Institutes of Health (NIH)\, in the \nDepartment of Radiology and Imaging Sciences she studied neuropathology in infectious diseases \nprimarily with MRI and PET imaging. She joined IISc in 2021 as an Assistant Professor in the \nDepartment of Bioengineering. At IISc\, her group focuses on biomarker development and translation \nwith MRI\, PET and photoacoustics to evaluate disease progression and treatment response noninvasively.\n\nHost Faculty:  Prof. Pavan Nukala.

SUMMARY:[Thesis Colloquium] : CVD of Graphene: 2D Crystal Growth Model\, Grain Size Control\, and Scalable Transfer via Mechanical Delamination
DESCRIPTION:Title: "CVD of Graphene: 2D Crystal Growth Model\, Grain Size Control\, and Scalable Transfer via Mechanical Delamination"\nName of the Student: Mr. Suman Kumar Mandal\nDegree Registered: Ph.D. Engineering \nAdvisor: Prof. Srinivasan Raghavan\, CeNSE\nDate: 10th October 2025\, Friday - Time: 3:30 PM\nVenue: ONLINE: https://shorturl.at/4xYib\n\nAbstract\n\nThe synthesis of large-area two-dimensional (2D) materials via chemical vapor deposition (CVD) \nhas garnered significant attention due to their potential in diverse applications. The deposition \nof these materials from the vapor phase occurs by the nucleation of atomically thin crystalline \nlayers and the subsequent motion of the edges or steps that bound the nuclei. Most theories of \ncrystal growth that address the motion of atomic steps were developed before the more recent \nadvent of 2D materials. They typically fall into two buckets. One\, based on the Burton-Cabrera-Frank\n (B.C.F.) theory that envisions growth through attachment of atoms to a thermally rough edge. \nA second approach is based on the so-called 1D nucleation mechanism\, which suggests growth via \nnucleation and propagation of atomic rows along smooth edges.\n\nAs summarized in this thesis\, they have shortcomings. To address these deficiencies and \nbuild upon their ideas\, a comprehensive analytical framework has been developed to \ninvestigate the growth kinetics of 2D materials. Graphene grown on copper serves as \nthe model experimental system. To the best of our knowledge\, the development of a theory \nand its application to 2D growth to test validity has not been done before. For atomically \nthin graphene edges\, a two-step growth mechanism involving double-kink nucleation at \ncrystal edges followed by subsequent attachment of additional units to these features \nis proposed. As in the B.C.F. and other subsequent theories\, a structure of the edge is \nfirst arrived at and modelled in terms of a kink density. The differences between the \nprevious models and the one proposed in this thesis are highlighted\, along with \nphysico-chemical parameter regimes in which they converge. Based on the interplay \nat these edges with the growth ambient\, four distinct growth modes were \nidentified: mono-nuclear\, poly-nuclear row-by-row\, poly-nuclear multi-row\, \nand dendritic modes that depend on crystal morphology\, size\, supersaturation\, \nand substrate chemistry. All three main aspects of 2D growth\, growth velocity\, \nsaturation nucleation density\,  and coverage with time\, are predicted. It is also \nshown that using this model\, 2D growth can be used as a probe to determine surface \nsupersaturation\, a parameter that is not otherwise available.\n\nLeveraging this mechanistic understanding\, this thesis demonstrates the ability to \ncontrol graphene grain size through supersaturation modulation\, achieving a \ntwo-order-of-magnitude tunability. Additionally\, the critical role of trace oxygen\n impurities in the copper substrate is discussed\, which is found to significantly\n impact the morphology of graphene single crystals and the grain size in the \nfull-coverage polycrystalline film. Understanding and modelling the growth mechanism \nof 2D edges is crucial as it directly influences grain size\, a critical parameter \ndetermining the suitability of 2D materials for specific applications. For instance\, \nlarge graphene grains are advantageous for electronics and impermeable barrier applications\, \nwhile smaller grains are preferred for chemical sensors.\n\nFinally\, to bridge the gap between synthesis and practical applications\, a scalable \nmechanical delamination method has been developed to transfer graphene films from copper\n to a target polymer substrate. This method overcomes the limitations of the conventional\n wet-transfer technique\, resulting in large-area\, defect-free\, and affordable transferred \ngraphene. The delaminated graphene exhibits state-of-the-art moisture impermeability of\n 2.7x10-3 grams/m2/day over a large area of 1-inch2\, demonstrating its potential for \nultra-high moisture barrier applications.\n\nIn summary\, this thesis provides a foundational understanding of the growth kinetics \nof 2D materials\, enabling precise control over their grain size for specific applications. \nMoreover\, the development of an efficient transfer method brings us closer to realizing \nthe full potential of CVD-grown graphene in various technological domains.

SUMMARY:[Thesis Colloquium] : Dismantling of the Mesothelial Barrier: A "Two-Hit" Model of Biochemical and Biophysical Stress Driving Ovarian Metastasis in the Peritoneum
DESCRIPTION:Thesis Title: Dismantling of the Mesothelial Barrier: A "Two-Hit" Model of Biochemical and Biophysical Stress Driving Ovarian Metastasis in the Peritoneum\n\nName of the Student: Mr. Satyarthi Mishra\n\nDegree Registered  : Ph.D. Engineering \n\nAdvisor  : Dr. Prosenjit Sen (CeNSE) & Dr. Ramray Bhat (DBG)\n\nDate : 17th October 2025  (Friday)\, 3:30 PM\n\nVenue:  CeNSE Seminar Hall (Hybrid)\n\nAbstract:\n\nOvarian cancer happens to be amongst the most lethal of gynaecological malignancies\, \nprimarily due to its propensity to metastasize through the peritoneum. This thesis \nproposes that successful metastatic colonization by ovarian cancer hinges on a progressive\,\n two-part failure of the peritoneal mesothelial barrier\, driven by distinct yet possibly \nsynergistic biochemical and biomechanical insults. By integrating findings from two distinct \nexperimental frameworks\, this work presents a unified model of stromal failure that uncovers a \nkey vulnerability for therapeutic intervention.\n\nThe first chapter demonstrates the biochemical priming of the peritoneum for invasion. \nWe demonstrate that elevated levels of the dicarbonyl methylglyoxal (MG)—a hallmark of systemic \nmetabolic stress associated with aging and diabetes—critically impair the mesothelium's defensive \ncapacity by reducing cell viability\, adhesion\, and motility. In contrast\, ovarian cancer cells thrive \nby upregulating the detoxifying enzyme Glyoxalase-1 (GLO-1)\, effectively weaponizing the toxic \nmicroenvironment to establish a path for invasion.  \n\nThe second chapter investigates the catastrophic mechanical breach of this pre-weakened barrier. \nUsing a first-of-its-kind distensible peritoneum-on-chip platform that recapitulates the physical\n forces of malignant ascites\, we found that mechanical distension alone significantly compromises\n mesothelial integrity\, leading to decreased viability and disordered cell motility. Consequently\,\n this mechanically weakened barrier is profoundly more susceptible to colonization\, with a significantly \nhigher degree of attachment followed by spreading of metastatic ovarian spheroids when compared to \nnon-distended control conditions.  \n\nTogether\, this research establishes a "two-hit" model where biochemical glycation via dicarbonyl \nstress acts as a "first hit" that sensitizes the peritoneum\, while the "second hit" of mechanical \ndistension due to ascites causes a catastrophic failure of this barrier. To conclude\, the thesis \nidentifies ovarian cancer's dependence on GLO-1 as a critical metabolic vulnerability\, suggesting \nthat inhibition of this enzyme might act as a potential therapeutic strategy to prevent metastatic \nprogression by dismantling the cancer's ability to engineer its own invasive niche.

SUMMARY:[Seminar] : Metal/Semiconductor Superlattices: Building Matter Layer-by-Layer
DESCRIPTION:Speaker: Dr. Bivas Saha\, Associate Professor\, International Centre for Materials Science & Chemistry and \n\nPhysics of Materials Unit\, Jawaharlal Nehru Centre for Advanced Scientific Research\, Jakkur\,.\n\nTitle: "Metal/Semiconductor Superlattices: Building Matter Layer-by-Layer"\n\nDate: Thursday\, October 23\, 2025 - Time: 4 PM\n\nHi-Tea & Coffee: 5 PM\n\nVenue: CeNSE Seminar Hall \n\nAbstract:\nSince the 1960s\, the quest to engineer artificially structured materials has driven efforts \nto combine metals and semiconductors at the nanoscale to unlock novel quantum functionalities. \nEarly metal/dielectric multilayers revealed intriguing tunnelling and optical properties but \nlacked atomic-scale interface control. To overcome this\, we developed the first epitaxial\, \nsingle-crystalline metal/semiconductor superlattices based on rocksalt nitrides\, featuring \natomically sharp\, defect-free interfaces that exhibit hyperbolic optical behaviour and \nunusual thermal transport phenomena.\n\nBuilding on this foundation\, we have now demonstrated a new class of epitaxial \nlattice-matched metal/semiconductor superlattices that transcend conventional structural \nconstraints by integrating refractory hexagonal transition metals with wide-bandgap III-nitride semiconductors.\n Exemplified by Hf/AlN superlattices\, these systems achieve coherent atomic-layer epitaxy and\, \nfor the first time\, exhibit cross-plane thermionic emission alongside enhanced Seebeck coefficients\n from carrier energy filtering. These advances establish metal/semiconductor superlattices as a \nversatile platform for exploring interface-driven quantum phenomena and developing next-generation \nmetamaterials and energy-conversion technologies.\n\nBiography:\n\nProf. Bivas Saha is an Associate Professor at the International Centre for Materials Science \nand the Chemistry and Physics of Materials Unit\, JNCASR\, Bangalore. He earned his Ph.D. from \nPurdue University (2014)\, M.S. from JNCASR (2010)\, and B.Sc. from Jadavpur University (2007)\, \nfollowed by Postdoctoral research at UC Berkeley. His group focuses on epitaxial thin films\, \nmetal/semiconductor heterostructures\, photonics\, and topological materials/devices. Prof. Saha \nhas published over 80 papers\, holds four patents\, and has guided multiple graduate students. \nHis honours include the DAE BRNS Young Scientist Research Award and the Sheikh Saqr Career Award. \nHe also serves as the Editor of Solid State Communications journal.\n\nHost Faculty:  Prof. Pavan Nukala.
