"Colloidal Semiconductor Quantum Well Supraparticles as Low-Threshold and Photostable Microlasers" published in Wiley's Advanced Materials Technologies This study compares micron-sized supraparticle (SP) lasers made from colloidal quantum wells (CQWs) and quantum dots (CQDs). CQW SPs show lasing thresholds twice as low (0.1–0.3 nJ) as CQD SPs (0.3–0.6 nJ), and a lasing emission stability more than 10 times higher. Picture: https://lnkd.in/gDbV2mVp

⚡🖥️🧪We found that #kinesin detaches fastest under an #electricfield in the X direction, followed by -X, Z, and -Z. This is due to kinesin's natural rotational movement along the X axis and the EF's effect on the β-#tubulin C-terminus, which plays a key role in kinesin binding.

Polarization Maintaining Fiber (PMF) is a specially designed optical fiber used to maintain the polarization state of transmitted light. Typically used in optical communications and sensing systems that require high stability and low polarization mode dispersion. Polarization-maintaining fiber has the following characteristics: 1.Birefringence: Polarization-maintaining fiber has high birefringence and can distinguish and maintain the different propagation speeds of two orthogonal polarization modes, thereby maintaining the polarization state. 2.Eliminate polarization mode dispersion: Through high birefringence, polarization-maintaining fiber can significantly reduce or eliminate polarization mode dispersion (PMD) and improve the transmission quality of the system. Common wavelengths: 850nm, 980nm, 1064nm, 1310nm, 1550nm, 1480nm. Application scenarios: Commonly used in fiber optic gyroscopes, fiber optic sensing, polarization-dependent fiber optic communication systems and other applications that require precise control of polarization states. #xhphotoelectric #opticalswitch #fiber #optics #sensing #photonics #광스위치 #섬유 #광학 #포토닉스 Read more https://lnkd.in/g9mptNAR
