Researchers developed a dual-mode magnetic elastomer that moves under a DC magnetic field and rapidly self-destructs under a high-frequency AC field, using embedded Fe₃O₄ nanoparticles to enable both actuation and heat-triggered degradation. advanced.onlinelibrary.wiley…

Today union minister Nitin Gadkari signed the file granting legal recognition to 100% ethanol fuel engine. Blend E10/E20 - most modern car after 2023 built to E20 spec But older car will run on material stress & mileage loss. E85 - Flex fuel vechicle only, 85% ethanol need ethanol sensor recalibrated ECU, cortisone resistance parts. E100 Flex dedicated ethanol vechicle only. Will Car Engines fail when we use E20 or above? 1. Corrosion - Ethanol attacks aluminium, brass, zinc and untreated steel. ORNL immersion data shows corrosion rising steadily with ethanol concentration. 2. Water absorption - hygroscopic it pulls moisture from air which pool near tank with it’s corrosivity accelerate wear on fuel system parts 3. Elastomer attack - it swells & degrades nitrile rubber, natural rubber, PVC, urethane seals & hoses of older fuel system 4. Cold start - E100 cold start will be very challenging Ethanol blend gasoline Mileage loss compare to petrol E10. -2% E20. -5% E85. -28% E100-33% Key property Petrol. Ethanol Energy density. 32. 21 Octane. 91-95. 108-109 Latent Heat. 350. 900 Water affinity. Low. Very high

3D-printed sensory conduit. • Hybrid TPMS-Auxetic lattice for dynamic protection. • Bio-conductive graphene-elastomer "nervous system." • Tuned for 10–500Hz ground-signature fidelity. We aren't just building a shoe. We are building a high-fidelity bridge between human

yes, as I understand it the elastomer material used in older fuel lines is technically incompatible.

Muchos gracias, Grok. That's how I envision it! No Cu or Si films involved as substrates to form boron ribbon. Just B. Best part is no part! Now let's talk optimal perfluroro-elastomer gasket thickness. No H2 leaks! "Flattened" tube with B ribbon enters reactor between flanges.

Looking for materials comparable to @Carbon EPU46 extra-soft elastomer for benchmarking Target 60A–65A Shore hardness Lower weight & cost Higher durability, reduced tackiness Low thermal sensitivity TPU 70A is still stiff. Haven’t found a reliable alternative. Any suggestions?

High-pressure O2 is murder on many materials; hope you can source a replacement rated for O2 at the valve's operating pressure. Probably Viton or a similar flouro-elastomer.

🚨: Researchers at Princeton University developed a soft robot shaped like an origami crane that can flap its wings without using motors, gears, or traditional moving parts. The robot is 3D-printed from a special material called a liquid crystal elastomer. When electric current heats flexible circuits embedded in its folds, the material contracts and triggers smooth, controlled movements.

Manual channel brushing is critical, but repetitive. Pull Thru™ uses 360° elastomer wiper technology designed to create suction against the lumen wall. Studies showed 1 pass removed as much soil as 5 passes with a standard bristle brush. #SPD #SPDTech #InfectionPrevention

He hasnt got "full female anatomy". He has a wound between his legs that his body is continuously trying to heal and pouches of an outer flexible elastomer (silicone) shell filled with either saline or a silicone gel inserted under his skin.

That's a lot of medical-grade silicone elastomer.
