Analytical Sciences, 1990 A method for the fluorometric determination of cadmium(II) is proposed. The metal reacts with Calcein in N, N-dimethylformamide and the cadmium(II)-Calcein complex formed presents an emission maximum at 534nm and several excitation maximum, the determination being carried out at an excitation wavelength of either 519 or 496nm.

Advanced Materials, EarlyView.We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.
