Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering
Advanced Materials Interfaces, EarlyView.A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

A method for using sub-Nyquist sampling for ultra low-power positioning systems [PDF]
, 2013 This paper proposes an improved Time-of-Flight (ToF) estimation algorithm that allows sub-mm position estimation and reduces the power consumption of the receiver. The former is ensured by employing a multicarrier ultra-wide band (UWB) signal. The latter
