Advances In Nanomaterials For Engineering Use

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.

🔬 When Big Energy Depends on Small Structures ⚡ In the world of electrochemical energy storage, the real breakthroughs aren’t happening at the gigafactory, they’re happening at the nanoscale. Because the way we synthesize and structure materials at nano- and microscale directly defines how fast ions move, how long electrodes last, and how safe batteries remain under stress. Here’s why nano- and microscale fabrication has become the heart of next-generation batteries 👇 1️⃣ Controlled Particle Morphology Nanostructured cathodes and anodes shorten ion-diffusion paths and enhance active surface area, boosting power density and rate capability. 2️⃣ Interface Engineering Atomic-scale coatings and surface modifications help form stable SEI/CEI layers, minimizing degradation and extending cycle life. 3️⃣ Porous and 3D Architectures Microstructured scaffolds improve electrolyte wetting, ion transport, and mechanical resilience, paving the way for flexible and solid-state designs. 4️⃣ Precision Fabrication Techniques From sol–gel synthesis and atomic layer deposition to 3D printing and laser patterning, these techniques allow researchers to tune structure–property relationships with near-atomic accuracy. 5️⃣ Scalability Challenge Translating nanoscale innovation into scalable, cost-effective manufacturing remains the biggest hurdle, but it’s one the battery community is steadily overcoming through hybrid processing and green synthesis routes. 💡 The future of batteries won’t just be bigger, it will be smaller. Because when we engineer matter at the nanoscale, we redefine how energy moves, stores, and sustains our world. 🔋 Small structures.

Thrilled to finally share the culmination of my work at MIT Chemical Engineering (ChemE) now out in Nature Magazine! Just in time before my next adventure at the University of Colorado Boulder officially begins. Access the article ➡️ https://lnkd.in/eqC3T5fy Quick research highlights can be found ➡️ https://lnkd.in/enjtKjN7 MIT News release ➡️ https://lnkd.in/eThBmSHi In brief, we demonstrated the first molecularly impermeable polymer thin film from 2D polyaramids. Although it's a polymer, its ability to stack densely to eliminate free volume allows it to restrict gas transport like inorganic 2D materials (e.g., graphene). These characteristics present myriad opportunities for innovation in next-generation barriers and future exploration of tangential spaces. This material promises not only exciting potential to scale for modern barrier needs like food packaging, microelectronic preservation, and a hydrogen economy, but it also enabled surprising discoveries related to nanoelectromechanical devices. Specifically, we showed the first polymer resonator approching molecular thinness (i.e., sub-10 nm) with resonance frequencies and quality factors similar to graphene. This was a massive undertaking that took several years of perseverence and patience, creativity, and of course a little bit of luck.

Recent advancements in atomic layer processing, particularly in Atomic Layer Deposition (ALD) and Atomic Layer Etching (ALE), have significantly improved the precision of gold manipulation at the atomic scale. Professor Seán Barry’s team pioneered a plasma-enhanced ALD (PEALD) method for depositing gold using a trimethylphosphine-supported gold precursor and plasma activation, which enables uniform gold films ideal for complex applications. The University of Helsinki recently introduced a thermal ALD process for 3D gold coatings using Me₂Au(S₂CNEt₂) and ozone, broadening the application range with continuous and conductive films. Complementing these deposition methods, Professor Steven M. George’s team developed a thermal ALE process for gold etching, using a two-step chlorination and ligand addition sequence to achieve controlled, self-limiting atomic removal. These combined breakthroughs allow for nanoscale precision in depositing and etching gold, with potential applications in electronics, catalysis, and surface engineering. #gold #ALDep #ALEtch #semiconductor Sean Barry University of Colorado Boulder@Carleton University Mikko Ritala

Our latest research is now published in Advanced Functional Materials! We explored how nanocomposites interact with very low frequency (VLF) and extremely low frequency (ELF) electromagnetic waves, a rarely studied domain. Our findings reveal that low-dimensional, high-aspect-ratio conductors can effectively shield long wavelengths by forming percolative networks—offering new insights for low-frequency shielding and guiding applications. Our proposed correlation to estimate shielding effectiveness based on conductivity and frequency paves the way for rational material design in electromagnetic interference shielding.

“The research uses a nanocomposite material comprising inorganic, hexagonal boron nitride (hBN) fillers embedded in a thermoplastic polymer. By carefully combining additives, surface treatments and thermal post-processing, the team created a crystalline polymer structure that bridges the highly conductive fillers, significantly enhancing thermal conductivity… The nanocomposite is first formed into continuous filament, which can then be fed into a desktop 3D printer to create complex structures such as heat sinks, thermal spreaders, mounting plates or panel covers. The 3D printing process further aligns the fillers, boosting the material’s performance.” #additivemanufacturing #3dprinting #army #usmilitary #research #materials #polymer #heat #thermalresearch #engineering
