Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

A Co‐Designed Implicit‐Reset Path PFD and Current Mismatch Compensated CP Enabling Sub‐0.5% Mismatch and Dead Zone‐Free for Low‐Spur PLLs

International Journal of Circuit Theory and Applications, EarlyView.
A co‐designed implicit‐reset phase‐frequency detector (PFD) and nonlinear amplifier‐assisted charge pump (CP) achieve dead zone‐free operation from 10 MHz to 4.7 GHz with < 0.5% current mismatch without calibration, enabling −80 dBc of reference spur and 0.50 ps of RMS jitter in a 180 nm of CMOS PLL.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
