Advanced Nanomaterials Synthesis

🔬 Pushing the Boundaries of Molecular Architecture A few years ago, we accomplished a rare feat in macromolecular chemistry: the synthesis and direct visualization of individual giant molecules - compact, globular nanostructures with molecular weights reaching up to 9 million Daltons. Synthesizing molecules of this scale is no small task. Their dense architecture (spanning tens of nanometers) and high viscosity during polymerization make control over molecular weight and branching extremely challenging. 💡 Our approach: a two-step anionic synthesis using glycidol as the building block. We first created a ~800 kDa precursor initiated by Trimethylolpropane (TMP), then used it as a macroinitiator to build semidendritic hyperbranched polyglycerols with molecular weights of 1, 3, and 9 MDa. 📏 These molecular giants were not only synthesized but also successfully visualized as single particles: ·      Cryo-SEM imaging confirmed spherical, single-particle morphology (28 - 51 nm) ·      AFM revealed compact, non-aggregating structures in water ✨ Visualizing individual giant molecules at this scale is a rare achievement. It provides direct insight into their morphology and stability - critical for advancing applications in nanomedicine, molecular delivery, and advanced materials. #chemistry #macromolecules #polymerchemistry #nanotechnology

Scientists have developed a new class of two-dimensional (2D) nanomaterials, known as MXenes, by incorporating up to nine different metals into a single atomic layer. These ultrathin materials, just a few atoms thick, exhibit enhanced stability and performance under extreme conditions such as high temperatures and radiation. The research team, led by experts at Purdue University, utilized a process that combines entropy and enthalpy to design these high-entropy MXenes. By carefully selecting and arranging various metal atoms, they created nearly 40 distinct layered materials, each with unique properties tailored for specific applications. This approach allows for the fine-tuning of material characteristics at the atomic level. These advanced MXenes are particularly promising for use in environments where traditional materials fail. Potential applications include aerospace technologies, clean energy systems, and deep-sea exploration, where materials must withstand harsh conditions without degrading. The ability to design materials with such precision opens new avenues for innovation in various technological fields. This breakthrough represents a significant step forward in materials science, demonstrating how the strategic combination of metals at the nanoscale can lead to the development of materials with exceptional capabilities.

Imagine running 3,600 synthesis experiments in a single day and learning something fundamental from each one. That's the power of Self-Driving Labs (SDLs). When I bring up SDLs with colleagues in biotech, the concept clicks instantly. The field already leans on robotic assays, high-throughput screening, and informatics pipelines. So it feels like a natural extension to integrate AI/ML for closed-loop optimization. But when I speak with peers in chemistry and materials science, I often encounter more hesitation. The idea of handing over experimental decisions to machines can feel at odds with a culture shaped by first-principles reasoning, serendipity, and manual iteration. That's why I was so intrigued when I met Prof. Milad Abolhasani at the NIST AI for Materials Science (AIMS) workshop last month. His lab’s work offers a compelling example of the SDL vision for materials discovery, bridging the gap between possibility and practice. From catalysis optimization to quantum materials, Abolhasani’s team is building SDL platforms that not only automate experiments, but also accelerate understanding. A recent standout is Rainbow: a multi-robot, AI-powered system that autonomously explores the synthesis of metal halide perovskite nanocrystals. By combining miniaturized batch reactors, real-time spectral feedback, and multi-objective Bayesian optimization, Rainbow executed thousands of synthesis trials in a single day: mapping Pareto fronts, uncovering structure–property relationships, and scaling up the best results. Maybe now is the time to imagine what SDLs could mean for materials innovation in your organization. 📄 Autonomous multi-robot synthesis and optimization of metal halide perovskite nanocrystals, Nature Communications, August 22, 2025 🔗 https://lnkd.in/euz72pXe

FROM GRAPHENE TO GOLDEN: ADVANCED SINGLE-ATOM SEMICONDUCTOR MATERIALS What is Golden? Researchers at Linköping University in Sweden have achieved a breakthrough by creating single-atom-thick sheets of gold, a material they've named "Goldene." This novel material holds promise for a variety of advanced applications, including carbon dioxide conversion, hydrogen production, and the synthesis of valuable chemicals. Shun Kashiwaya, a researcher at the University's Materials Design Division, explained:“If you make a material extremely thin, something extraordinary happens – as with graphene. The same thing happens with gold. As you know, gold is usually a metal, but if a single atom layer is thick, the gold can become a semiconductor instead.” The creation of Goldene began with the development of a three-dimensional "base material" – a layered structure of gold embedded between titanium and carbon. Under high temperatures, the silicon layers within this titanium silicon carbide structure were replaced by gold, unexpectedly yielding titanium gold carbide. Particularly, the exfoliation of single-atom-thick gold achieved through wet-chemically etching away Ti3C2 from nanolaminated Ti3AuC2, initially formed by substituting Si in Ti3SiC2 with Au. Ti3SiC2 is a renown MAX phase, where M is a transition metal, A is a group A element, and X is C or N. The developed synthetic route is by a facile, scalable and hydrofluoric acid-free method. The two-dimensional layers are termed goldene. This discovery was serendipitous; the researchers' initial goal was simply to coat the electrically conductive titanium silicon carbide with gold to improve its electrical contact. This new method for creating Goldene is simple, scalable, and avoids the use of hydrofluoric acid. Electron microscopy reveals that the Goldene layers exhibit approximately a 9% lattice contraction compared to bulk gold. While simulations (AIMD) suggest that Goldene is inherently stable in two dimensions, experiments have shown some curling and agglomeration. These issues can be addressed by using surfactants to stabilize the Goldene sheets after they are exfoliated from the gold-intercalated MAX phases (the layered precursor material). Goldene holds immense potential across diverse fields, including carbon dioxide conversion, hydrogen production, catalysis for valuable chemical synthesis, water purification, and even communication technologies. Looking ahead, the research team aims to minimize the gold content required for these applications and investigate the use of other noble metals as substitutes. These new materials could unlock even more applications. #https://lnkd.in/eAbBH337

Magnetized Plasmas Could Revolutionize Nanomaterial Design Introduction Physicists at Auburn University have discovered that even weak magnetic fields can dramatically alter how nanoparticles form and grow inside dusty plasmas—charged particle clouds that occur in space and laboratory experiments. The findings, published in Physical Review E, could reshape how scientists engineer nanomaterials for electronics, coatings, and quantum technologies. The Discovery A dusty plasma is a complex mixture of ions, electrons, and tiny dust grains suspended in a gas—essentially a glowing, electrically active cloud. By applying small magnetic fields to such plasmas, the Auburn team found they could accelerate or decelerate nanoparticle growth, influencing both particle size and lifetime. Lead author Bhavesh Ramkorun explained: “We found that by introducing magnetic fields, we could make these particles grow faster or slower, and the dust particles ended up with very different sizes and lifetimes.” Experimental Findings Researchers used a plasma of argon and acetylene gas to grow carbon nanoparticles. Without magnetization, particles grew for about two minutes before dispersing. When weak magnetic fields were applied, the growth cycle shortened to under a minute, and particles remained smaller. The magnetic fields forced electrons into spiral trajectories, reorganizing the plasma and changing how particles acquired charge—effectively rewriting the growth rules. Co-author Saikat Thakur added: “Electrons are the lightest players in the plasma, but when they become magnetized, they dictate the rules. That simple change can completely alter how nanomaterials form.” Implications for Science and Technology This work provides a new lever for precision control in nanomaterial fabrication. By tuning magnetic fields, scientists could design nanoparticles with custom shapes, sizes, and electrical properties—crucial for next-generation semiconductors, catalysts, and quantum devices. Beyond technology, the research offers a window into cosmic plasma processes, shedding light on how magnetic fields influence dust formation in planetary rings, comet tails, and the solar atmosphere. As Ramkorun summarized: “Plasma makes up most of the visible universe, and dust is everywhere. By studying how the smallest forces shape these systems, we’re uncovering patterns that connect the lab to the cosmos.” Conclusion The discovery that gentle magnetic fields can control nanoparticle growth inside plasmas bridges materials science and astrophysics, unlocking new methods for both manufacturing innovation and understanding the universe’s most abundant matter.
