Almanac An Alloy That Refuses to Grow
  • What nickel-steel composition gives Invar a thermal expansion coefficient near zero?
  • Why was a stable metrological standard so important to the International Bureau of Weights and Measures in the 1890s?
  • How did Invar change the precision of pendulum clocks and surveying instruments?
Almanac Looking Where No One Thought to Look
  • Why did the conventional wisdom in 1986 hold that ceramics were an unpromising place to look for superconductivity?
  • What transition temperature did Bednorz and Müller find in their barium-lanthanum-copper-oxide ceramic, and how did it compare to the previous record?
Finding Ceramic Particle Filled Polymer Filaments for FDM 3D Printing
  • How does ceramic loading percentage determine whether a filament yields an enhanced polymer composite or a fully ceramic sintered part?
  • What post-processing steps (debinding and sintering) are required to turn a printed green body into a fully dense ceramic part?
  • What practical challenges do makers face when working with ceramic-filled filaments, including nozzle wear, particle settling, and sintering shrinkage?
