Feeling motivated and enriched after attending the seminar organised by the Scholars of KSK ACADEMY ,CHENNAI ! It was an incredible opportunity to hear from experts and gain valuable insights on the talk " From Cyrstals to Molecules : Principles of Crystal Structure Determination " Principles of Crystal Structure Determination : This technique involves analyzing the diffraction patterns produced when X-rays are directed at a crystalline material. By interpreting these patterns, scientists can infer the three-dimensional positions of atoms within the crystal. This information is crucial for understanding the material's properties and behavior at the atomic level, impacting fields such as chemistry, biology, materials science, and physics. #XRayDiffraction #CrystalStructure #AtomicPositions #MaterialProperties #DiffractionPatterns #StructuralAnalysis #MaterialsScience #Chemistry #Biology #Physics #AtomicLevel #ScientificResearch #Crystallography #AdvancedMaterials #MolecularStructure

🌟 New Publication Alert! 🌟 I'm excited to share the second article from my PhD research, supervised by Prof. Juarez L. F. Da Silva 🇧🇷, in collaboration with Pedro Ivo Rodrigues Moraes and  Albert F.B. Bittencourt. 📄 Title: Unveiling the impact of organic cation passivation on structural and optoelectronic properties of two-dimensional perovskites thin films 🔍 Abstract: We conducted density functional theory (DFT) calculations to explore the effects of 17 different organic cations on the passivation of thin two-dimensional perovskite films, specifically focusing on how these cations interact with the inorganic framework (PbI₆-octahedra). Our findings reveal that Brønsted–Lowry acid–base interactions, alongside H-bond formation facilitated by oxygenated groups (-OH, -COOH), significantly enhance the energetic stability and electron density localization between layers. Among the cations studied, 4-fluorophenylethylammonium (FPEA), phenylethylammonium (PEA), and butylammonium (BtA) show the highest potential for real-world applications. 📚 Read the full article here: https://lnkd.in/dXYr6Pca #MaterialsScience #Perovskites #DFT #Research #Chemistry #PhD #AcademicPublishing #ThinFilms

At the University of Guam, chemistry students are seeking to better understand the composition of their crystals. To achieve this goal, they're making use of the elemental analysis feature of their Phenom XL Desktop Scanning Electron Microscope (SEM), made possible by an integrated energy dispersive X-ray spectroscopy (EDS) detector. It is great to see Christopher S Lobban, PhD, Professor Emeritus of Biology and Senior Researcher of UOG impart on Dr. MAIKA VUKI and his students the EDS knowledge he gained at our Phenom SEM Short Course! #electronmicroscopy #microanalysis #microscopy #chemistry #university #SEM #EDS #PhenomDesktopSEM

Join the NMR crystallography Faraday Discussion! The meeting is being held from 4 - 6 September 2024 in Birmingham, United Kingdom. There is still time to submit a oral abstract. The deadline has been extended to 22 January 2024. More information here: https://lnkd.in/e_zDCZ9v This meeting is aimed at established and early-career scientists, post-graduate students and industrial researchers interested in NMR crystallography and related techniques. The unique format of the Faraday Discussions will allow for in-depth discussions of emerging computational and experimental methods in the field of NMR crystallography, as well as the current limitations and challenges that need to be overcome to broaden applications to increasingly complex materials. #conferences #chemistry #FaradayDiscussion #NMR #Crystallography

Absolute delight to attend lectures and lead a few tutorials at the Abdus Salam International Centre for Theoretical Physics (ICTP)-Tata Institute of Fundamental Research (TIFR)-ICTS Quantitative Systems Biology Winter School on Bioenergetics in Bangalore, Dec 4-15, 2023. Dr Xingbo Yang, TU Dresden and I presented a formalism to integrate Active Matter and Energy Metabolism. The 3 tutorials I led were: T1: Simulating Active Matter-Viseck Model (and modifications) T2: Pattern formation via Reaction-Diffusion Systems T3: Quantitative Image Analysis of Fluorescence Lifetime Imaging Microscopy (FLIM)

It’s a kind of magic: Assembly of a molecular 819 knot 💥🧪⚗️👌 The approach was used to make a molecular knot consisting of a 192-atom (20 nm) continuous loop interwoven with eight non-alternating crossings (Figure 2). It is the mostly tightly knotted physical structure known at ~2.5 nm (24 atoms) per crossing. Unusually, the molecular knot can be made in right or left handed forms solely by virtue of its topology (the knot possesses no elements of Euclidean chirality – stereogenic centers such as asymmetric atoms, helical subunits, etc. which are usually found in molecules of single handedness) Being able to make different types of molecular knots means that scientists should be able to probe how knotting affects strength and elasticity of materials and may enable them to weave polymer strands to generate new types of material. The first synthetic molecular knot, a trefoil knot, was made by Jean-Pierre Sauvage’s group in 1989.5 For related synthetic strategies applied in the field of artificial molecular machines Sauvage shared the 2016 Nobel Prize in Chemistry.8 More than six billion different prime knots are known to mathematics;9 in the quarter of a century since Sauvage’s breakthrough chemists have been able to make just four different types of knot. The synthesis of the molecular 819 knot illustrates a strategy (the braiding of three strands) that should be applicable to the synthesis of many more, and more diverse, types of molecular knots. By making different types of molecular knot we can find out about their properties (such as at which point are entangled molecular strands prone to breaking?) and which knots have properties best suited for a particular purpose, just as a fisherman or sailor knows which knot is best suited for each task. #organicchemistry #synthesis #nanotechnology #nanomaterials #nanoparticles #nanomedicine #polymers #nanochemistry #materials #Supramolecularchemistry #greenchemistry #nanoscience #phdposition #greenchemistry #inorganicchemistry #chemistry #newmolecules #nanocomposite #newstructure #MolecularMachine #analyticalchemistry #Noble #molecularknot
