Jackson and C.J. Wood Professor of Chemistry at Stanford University, presented her team’s latest work on mosaic perovskites at the ACS Spring Meeting in San Diego. Her talk highlighted how mechanochemical milling can create complex perovskite alloys with unique metalstoichiometries and emphasized the fact that these structures cannot be made through traditional solution-based methods. Furthermore, the resulting materials from mechanical milling show intriguing optical and magnetic properties, and provide new insights into local packing and orbital interactions in perovskites.  \nA recent publication in RSC Mechanochemistry from the Martini and Hanusa labs explores how subtle changes insolvent conditions can dramatically alter the outcomes of nickel-based mechanochemical reactions. The team reacted a bulky allyl anion salt with nickel halides under three conditions: without solvent, with a small amount of pyridine, and in pyridine solution. Each condition led to adifferent reaction pathway. In some cases, halide metathesis produced the allyl complex in nearly quantitative yield. In others, a redox process generated allyl radicals that coupled to form a diene. Using Density Functional Theory, the researchers showed that pyridine weakens the nickel chloride bond and enables metathesis, while solvent-free conditions favor the redox route. These insights offer new tools for understanding and controlling solvent-assisted grinding reactions at the molecular level.  \nDr. Carpick Honored for Outstanding Student Advocacy  \nDr. Robert Carpick, John Henry Towne Professor at the University of Pennsylvania, was awarded the Michael L. Barrett (ENG’89) and Traci Barrett (W’91) Faculty Award for Student Advocacy from the School of Engineering and Applied Sciences at the University of Pennsylvania. This award recognizes a member of the Penn Engineering faculty for their exceptional support of undergraduate students and their outstanding commitment to building community. This student-nominated annual award was decided by the Penn Engineering's Underrepresented Student Advisory Board in Engineering (USABE) and the Engineering Deans’Advisory Board (EDAB).  \nScan the QR code to access the Spanish version!¡Escaneeel código QR para accedera laversiónen español!  \nDr. Kumar Presents at UC Merced & ACS Spring 2025  \nDr. Sourabh Kumar, a postdoctoral researcher in Prof. Ashlie Martini’s group at the University of California, Merced, recently gave a guest lecture to UC Merced undergraduate and graduate students on Computational Tools in Mechanochemistry. His talk covered the implementation of mechanical forces at both atomic and bulk scales to model mechanochemical reactions. Additionally, Dr. Kumar presented a collaborative project with Prof. Timothy Hanusa (Vanderbilt University) atthe ACS Spring 2025 conference in San Diego, highlighting the role of solvents in influencing mechanochemical processes.  \nNew Publication in RSC Mechanochemistry  \nAditya Rao Wins ACS Chemistry Award at NJ STEM Fair for CMCC Research  \nHigh school student Aditya Rao, who worked in Dr. Carpick’s lab at the University of Pennsylvania during Summer 2024, was recognized for his CMCC research at the Terra North Jersey STEM Fair (TNJSF) held March 22–23 at Kean University. Under the mentorship of CMCC graduate student Will Oprisu, Aditya presented on mechanochemistry and lubricant solvents, comparing PAO40 to toluene and other typical solvents used in the Diels–Alder reaction. His project supported PAO40 as a viable solvent based on solubility and reaction yields. For this work, Aditya received the Chemistry Special Award First Place from the American Chemical Society, earning a certificate, plaque, and a $250 prize.  \nDr. James Batteas ","cbCaip7adviSvsn7","https://ap.wps.com/l/cbCaip7adviSvsn7","pdf",12981653,"English","# NSF Center for the Mechanical Control of Chemistry\n## April 2025 Research Highlights\n## Awards and Recognition","[{\"question\":\"What mechanochemical process is highlighted in the perovskite work by Dr. Karunadasa?\",\"answer\":\"The newsletter describes mechanochemical milling to create mosaic perovskite alloys with specific metal stoichiometries that cannot be produced by traditional solution-based methods.\"},{\"question\":\"How do solvent and pyridine affect nickel-based mechanochemical reactions in the RSC Mechanochemistry publication?\",\"answer\":\"Without solvent, conditions favor a redox pathway, while adding pyridine weakens the nickel chloride bond and enables halide metathesis, leading to different reaction outcomes and products.\"},{\"question\":\"What is the purpose of the CMCC open-access Mechanochemical Reactions Database mentioned in the newsletter?\",\"answer\":\"The database is presented as an open-access resource to support collaboration and machine learning efforts across the mechanochemistry community.\"}]","Crushing Chemistry - April 2025 | PDF",1789998651]
