Tiny Black Particles Could Revolutionize 3D Printing!

🖨️ New research reveals how carbon black nanoparticles supercharge polymer powders for laser 3D printing:

✔ 14x better laser absorption (key for energy-efficient printing)
✔ Surface coating works best – boosts performance without clumping
✔ Preserves powder quality vs. mixing nanoparticles throughout

Why it matters:
3D printing with near-infrared lasers is faster/cheaper, but most plastics don’t absorb the light well. This fix could transform manufacturing in aerospace, medicine & more!

"Where you put the nanoparticles changes everything," say researchers. Surface-coating beats mixing them in.

Black Coffee = Longer Life? ☕ New Study Reveals the Catch!

  Want to boost your longevity? Skip the sugar and cream! A   Tufts University study   of 46,000+ adults found: Black coffee drinkers  had a  14% lower risk of early death  vs. non-coffee drinkers. Added sugar/fat (milk, cream)  canceled these benefits entirely. 2–3 cups/day  was the "sweet spot" for health perks. 🔬  Key Findings: ✔ Caffeinated coffee showed benefits; decaf did not. ✔ Bioactive compounds in coffee may protect health—but additives dilute effects. ✔ Aligns with  U.S. Dietary Guidelines  to limit added sugar/saturated fat. 💡  Pro Tip:  Love milk in your coffee? Try  unsweetened almond or oat milk  to keep it healthy! #CoffeeLovers #LongevitySecrets #HealthyAging #NutritionScience #BlackCoffee Reference Bingjie   Zhou   ,  Mengyuan   Ruan   ,  Yongyi   Pan   ,  Lu   Wang   ,   Fang Fang   Zhang (2025)  Coffee Consumption and Mort...
