Advanced Functional Materials, EarlyView.For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Dielectric Losses of Doped Colored Crystals
The Journal of Chemical Physics, 1957 The dielectric losses of KBr single crystals doped with BaBr2 at different concentrations, both uncolored and additively colored, have been measured. A maximum in the dielectric loss versus frequency curve in the additively colored crystal was observed. This relaxation maximum was found to be due to the presence of Z2 centers.
