Researchers have developed fluorescent polymers whose colour can be easily tuned. Depending on their length, the polymers emit a different colour. Potential applications include biomedicine, security printing and solar energy.
Chemists and materials scientists have demonstrated a new reaction pathway that enables such control for carbon nanotubes. It results in specific optically active sp3 defects, which are more luminescent and can emit single photons in the near-infrared.
Cleanroom-compatible, this high performance noncontact positioner is well-suited for wafer inspection, fiber positioning, optics positioning, flat screen inspection, maskless lithography, and micron-LED manufacturing.
Researchers have made a significant discovery in the field of materials science, for the first time providing a full picture of how fatigue in ferroelectric materials occurs.
