Great to see the use of crystal engineering expanding from small molecules to polymers using one of CCDC tools of Isostar! Have read of the blog for a great summary with links to the full paper for those who want to learn even more 😀

💡Expanding the scope of crystal engineering from small molecules to polymers. The scientists used a knowledge-based approach that accessed the curated structural data in the Cambridge Structural Database, and its library of intermolecular interactions, to design a new isostructural cocrystal of a polymer. 🔗https://lnkd.in/e4zGb9d5 #Cocrystals #CocrystalDesign #Crystallography

Tuesday publication post! 📖 In this newest research, authors look at thermoelectric materials which can convert heat into electricity. Using the #FusionAX system, they were able to follow grain boundary changes at elevated temperatures! 💡Traditional high-temperature synthetic methods are normally hindered in synthetic methods, the ability to surpass crystal structure limitations and engineer defects. In this study, a new synthesis method is explored by the usage of powders and densification at lower temperatures. 🔥This latest study focuses on Ag2Se, an n-type alternative to bismuth telluride. Through meticulous control of sintering temperature, a direct correlations between the concentration of Ag interstitials, grain boundaries, dislocations, and material microstructure was observed. 🔬The microstructrual changes were followed using in situ electron microscopy at elevated temperatures. Starting from focused ion beam (FIB) lamella preparation, the samples were heated up to 160 °C to observe grain orientation and coalescence. These examples emphasize the transformative potential of innovative synthetic approaches in reshaping the landscape of thermoelectric materials and opening avenues for unprecedented advancements in the field. The video shows both the microstructural transformation (right) and the diffraction pattern (left) during the transformation. Want to read the entire study?

We are excited to announce the publication of our latest research paper titled "Combined Experimental and Computational Insight into the Role of Substrate in the Synthesis of Two-Dimensional WSe2," now available in the Journal of ACS Applied Materials & Interfaces. 🔗 [Read the full paper here](https://lnkd.in/e2xVD2mY) This study provides significant insights into the synthesis of two-dimensional WSe2 monolayer films using chemical vapor deposition (CVD), particularly focusing on the effects of different substrates. Here’s what we found: - The 0° rotated WSe2 on sapphire substrates is the most favorable combination for creating large-area monolayer films, facilitated by an eggshell surface potential that minimizes the energy barrier. - On quartz substrates, except for a 0° misorientation, the energy landscape appears striped, promoting seamless coalescence of WSe2 in all directions and eliminating any preferred growth orientation. - The binding energy between WSe2 monolayers and crystalline substrates proves higher compared to their amorphous counterparts, revealing key insights for future applications in material transfer and device fabrication. - Interesting substrate interactions were noted where the equilibrium distance of monolayer WSe2 increases or decreases based upon the amorphization of the SiO2 (Al2O3) substrate. We appreciate the hard work and dedication of our team and collaborators in bringing this study to light. Feel free to share your thoughts and discuss these findings with us! #MaterialsScience #TwoDimensionalMaterials #WSe2 #CVD #ACSAMI #ResearchPublication #ScienceandEngineering

Another work, published in Chem Eur J (Chemistry Europe), exploits the conformational plasticity of the #Gquadruplex. (poke Jagannath Jana) Here we designed a quadruplex-duplex hybrid that is polymorphic and whose conformations are pH sensitive. N1-protonated adenine (even at pH 7), which forms an unprecedented quartet, is critical for the topology found under acidic conditions. The topological interconversion can be followed with thiazole orange, which may not be the most efficient signal transducer. Another potential improvement is to speed up the kinetics of the interconversion. Nonetheless, this works shows strong structural evidences that G-quadruplex can be potentially be used as molecular switch. I am really grateful for Klaus Weisz lab for all the trainings and opportunities.
