The strength of metals and alloys at elevated temperatures typically decreases due to the recovery, recrystallization, grain growth, and growth of second-phase particles. We report here a cold-worked Cu-AlO composite did not recrystallize up to a temperature of 0.83T of Cu.

- Electrical switching of ferroelectric domains enhances piezoelectric activity but typically reduces optical transparency due to light scattering at domain boundaries.
- Researchers demonstrated that ferroelectric domains in specific perovskite crystals can be manipulated to convert an opaque structure into a transparent one with low electric fields, maintaining strong piezoelectric properties.
- This dual control over optical and piezoelectric characteristics opens up opportunities for developing advanced photonic devices.
Sensors containing metal-carbon nanotube (CNT) hybrid materials as the active sensing layer were demonstrated for ethanol vapor detection at room temperature. The metal-CNT hybrid materials were synthesized by infiltrating single wall carbon nanotubes (SWNTs) with the transition metals Ti, Mn, Fe, Co, Ni, Pd or Pt. Each sensor was prepared by drop-casting dilute dispersions of a metal-CNT hybrid onto quartz substrate electrodes and the impedimetric responses to varying ethanol concentration were recorded.
