Advanced Materials For Engineering

𝗜𝗺𝗽𝗿𝗲𝘀𝘀𝗶𝘃𝗲. 𝗪𝗶𝗿𝗲𝘀 𝘁𝗵𝗮𝘁 𝗱𝗼𝗻’𝘁 𝗯𝗿𝗲𝗮𝗸. 👏 Researchers in China have developed a Metal-Polymer Conductor (MPC) by combining elastic polymers with liquid metals like gallium and indium. The result is quite remarkable. A circuit that can: → stretch → twist → fold → bend repeatedly …and still conduct electricity. Traditional wires fail under stress. This material behaves more like living tissue. Which opens interesting possibilities. → wearable electronics → soft robotics → medical sensors → even artificial skin Working in automation and AI, I find breakthroughs like this fascinating. Because the future of intelligent machines will not just depend on better software. It will also depend on new kinds of hardware that can move, flex, and interact safely with the human world.

This imec roadmap to 2039 (!) has become the chip industry's go-to. So what's actually on there? 🔎 Let me walk you through it! 👇 🔢 𝗧𝗵𝗲 𝗻𝗼𝗱𝗲𝘀 𝗮𝗻𝗱 𝘁𝗵𝗲𝗶𝗿 𝘆𝗲𝗮𝗿 𝗼𝗳 𝗶𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻  Nodes set the tempo for innovation. They are generational markers for density, performance and power improvements. So as we exit the "N" nodes and enter the "angstrom era" (A14, A10, A7…), remember: 10 angstroms = 1 nanometer. Just remember that these numbers no longer relate to anything physical on the chip. The naming is more competitive signaling between leaders like TSMC, Samsung Semiconductor and Intel. But the engineering behind each step is very real. 🧱 "𝗗𝗲𝘃𝗶𝗰𝗲 𝗮𝗻𝗱 𝗺𝗮𝘁𝗲𝗿𝗶𝗮𝗹 𝗶𝗻𝗻𝗼𝘃𝗮𝘁𝗶𝗼𝗻𝘀" 𝗶𝘀 𝗮𝗯𝗼𝘂𝘁 𝘁𝗵𝗲 𝘁𝗿𝗮𝗻𝘀𝗶𝘀𝘁𝗼𝗿𝘀 New transistor architectures deliver better performance. In FinFET transistors, the gate wraps around the channel on three sides of a silicon fin. It was the workhorse from ~22nm. Right now, the first generation of Gate-All-Around (GAA) transistors is entering production. These stacks horizontal sheets with the gate wrapping the channel on all four sides for better control and less leakage. Next up: Complementary FET (CFET) transistors. Their taller design stacks a pair of transistors on top of each other to essentially create two transistors in one fin. At the tail end: '2DFET' points to the use of 2D materials with atomic-scale thickness (~0.7nm) that could work where silicon can't. Deep future stuff. 📏 "𝗖𝗼𝗻𝘁𝗶𝗻𝘂𝗲𝗱 𝗱𝗶𝗺𝗲𝗻𝘀𝗶𝗼𝗻𝗮𝗹 𝘀𝗰𝗮𝗹𝗶𝗻𝗴" 𝗶𝘀 𝗮𝗯𝗼𝘂𝘁 𝗹𝗶𝘁𝗵𝗼𝗴𝗿𝗮𝗽𝗵𝘆  Litho enables economic scaling. ASML's Extreme ultraviolet (EUV) lithography enables today's most advanced nodes and will continue to keep the pace of chip innovation. As chip designs continue to scale and become more complex to print economically, the door to the next generation of lithography opens. We're now on the cusp of the High NA EUV era. By increasing the numerical aperture from 0.33 to 0.55, these systems bring imaging resolution down to 8nm. And an even higher numerical aperture of 0.75 would give rise to "Hyper NA" EUV systems in the 2030s. ⚡ "𝗖𝗵𝗶𝗽 𝗶𝗻𝘁𝗲𝗿𝗰𝗼𝗻𝗻𝗲𝗰𝘁 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲" 𝗶𝘀 𝗮𝗯𝗼𝘂𝘁 𝘁𝗵𝗲 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗲𝗱 𝗰𝗶𝗿𝗰𝘂𝗶𝘁𝗿𝘆 This is about the wiring. Today, power travels from the top through many wiring layers to reach transistors, wasting space and energy. Backside Power Delivery (BSPDN) flips the script: it routes power from the bottom via through-silicon vias, freeing the frontside for denser routing and better performance. Intel, TSMC and Samsung are all adopting this in their advanced nodes. But the complexity demands collaboration across deposition, etch, CMP, bonding and wafer thinning. 💡 In the end, a roadmap like this shows that everything has to work together. No single breakthrough carries that pace of innovation. That's what makes this industry incredibly competitive and collaborative at the same time! ❤️

The dirty secret of Quantum Computing… Materials are the limiting factor. Everyone talks about quantum algorithms, error correction, and qubit counts. But the real killer of quantum computing isn’t software, it’s materials. Superconducting qubits don’t decohere because we lack clever code. They decohere because: – Surface oxides introduce two-level system noise. – Impurities and defects act like microscopic time bombs. – Atomic-scale disorder destroys coherence before circuits can compute anything useful. That’s why the biggest breakthroughs aren’t happening in code, they’re happening in materials labs. → Google is building qubits with ultra-clean Al/Si interfaces to suppress noise. → IBM is investing in substrate purification to push coherence times further. → Labs worldwide are chasing epitaxial aluminum films with sub-ppm impurity levels. The “quantum revolution” is being held back by dirt, literally. Until we tame materials noise, scaling qubits is just scaling errors. Quantum doesn’t need another hype cycle. It needs a materials breakthrough. #QuantumComputing #MaterialScience #GrowthAndInnovation #DeepTech

>>For nearly 200 years, #metals have obeyed the #Wiedemann-Franz law – the rule that electrical conductivity and thermal conductivity always rise and fall together. But in ultra-clean #graphene, researchers at the Indian Institute of Science (IISc) [Arindam Ghosh Lab] found the opposite. ''As electrical conductivity increased, thermal conductivity dropped, shattering a principle taught in every physics textbook.'' 🔬 Key Findings: 📣 #Quantum critical Dirac fluid realised in #graphene: Near the Dirac point (i.e. when the charge carrier density is almost zero), graphene behaves like a quantum critical fluid; both charge and heat flow are governed by universal laws rather than material-specific impurities. Nature Magazine 📣Universal (quantised) d.c. electrical #conductivity: They observe that the conductivity converges to a characteristic, quantised value in very clean graphene devices, consistent with predictions for a quantum critical point. 📣 Violation of the Wiedemann–Franz (WF) law: Close to the #Dirac point and at low temperatures, the #Lorentz_number (which relates thermal to electrical conductivity) exceeds the usual semiclassical value by over 200×. This shows that heat and charge transport are decoupled in remarkable ways under these conditions. 📣Effective viscosity nearing minimal quantum limit: At higher #temperatures, the ratio of dynamic viscosity to entropy density in the cleanest devices comes close (within a factor of ~4) to the lower bound predicted for minimally viscous quantum fluids. This suggests graphene’s electron fluid is behaving almost like a “perfect” fluid in relativistic hydrodynamics. 🧠 #Why_It_Matters 1.) Provides experimental evidence for theoretical predictions about quantum criticality in Dirac materials, showing universal #transport behavior in both charge and heat channels. 2.) Deepens understanding of hydrodynamic electron flow in 2D materials- essential for next-generation electron devices where interactions, rather than scattering off impurities, dominate. 3.) Challenges traditional transport paradigms (like the WF law), which assume that electrons’ abilities to carry heat and charge are tightly linked — here, they are not. 🎯 #Implications_and_Further_Directions > Potential for exploiting quantum critical behavior in designing low-dissipation electronics, thermal management, or novel sensors. > Opens up further experimental/theoretical work in exploring other #materials or regimes (e.g. stronger interactions, different dimensionalities, non-linear responses) to test universality. > Could have connections to high energy physics concepts (relativistic hydrodynamics, minimal viscosity bounds) being realised in a solid-state platform. #FUll paper : https://lnkd.in/gh-Nis8D #solidstatephysics #electricalconduction #graphene Research & Innovation Center for Graphene and 2D Materials (RIC2D) Pattern Materials Graphene GAMlab (Graphene and Advanced Materials Laboratory)

Caltech has just flipped centuries of metalmaking on its head with a method that crafts alloys with surgical precision instead of brute force. By 3D-printing a hydrogel scaffold, soaking it in metallic salts, burning away the gel to leave metal oxides, and then stripping out oxygen in a hydrogen-rich environment, they can build parts atom by atom with exact compositions—no guesswork, no endless trial and error. The kicker? They can instantly fine-tune ratios—like shifting from a copper-heavy blend to a Cu12Ni88 mix nearly four times stronger—without altering the shape or tooling, turning metallurgy into a high-tech art form where strength, density, and performance are all set by design. https://lnkd.in/eVEZmsRZ FuturistSpeaker.com

Excerpt from EU Corner: "Japan has developed a cooling fabric that doesn’t just reflect heat — it actively lowers body temperature A team of Japanese material scientists has unveiled a smart fabric that could change how we dress for extreme heat. This isn't ordinary clothing — it's engineered with nano-crystals that reflect infrared radiation and draw heat away from the body like a wearable heat sink. The fabric is breathable and lightweight, yet it actively cools the skin through a passive thermoelectric effect. Unlike typical moisture-wicking materials that rely on sweat evaporation, this textile absorbs no water — instead, it redirects thermal energy outward without trapping humidity. Lab tests showed body temperatures dropping by up to 3.5°C while walking under direct summer sun, without fans, batteries, or chemicals. It’s a completely passive system — one that works silently with no moving parts. The potential uses are wide-ranging: protective clothing for construction workers, safer uniforms for firefighters, even everyday wear in a rapidly warming world. It could also play a crucial role in elderly care and humanitarian aid during heatwaves. Japan is now pushing to mass-produce this textile for the upcoming Osaka World Expo, where it will be worn by staff working long shifts in outdoor zones."

Sweden has just unveiled wood that’s not only transparent—but stronger than glass. Engineered by removing lignin from natural wood and infusing it with polymers, this new material allows light to pass through while maintaining structural toughness. The result? A glass-like panel made from trees that’s biodegradable, impact-resistant, and provides excellent insulation. The breakthrough could replace traditional glass in windows, greenhouses, and even solar panels—making architecture greener and more energy-efficient. It’s strong, it’s clear, and it grows from the forest.

Now that’s the future I want to walk on. Japanese researchers have created a flexible concrete that can resist earthquakes by bending instead of cracking.  Instead of shattering under pressure, this material absorbs the shock,  protects the structure, and saves lives. They achieved it by incorporating special polymers and microfibers that allow the concrete to flex under extreme pressure.  It is not only stronger but also lighter and smarter than traditional concrete. By absorbing shocks instead of fracturing, it dramatically reduces reconstruction costs after earthquakes. A nd it can even be used to reinforce existing bridges, buildings, and critical infrastructure. This kind of breakthrough reminds me why I love planning and designing so much. When the smartest ideas are built for the people, making their lives safer, easier, and more resilient. That is the real impact of great engineering.
