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

open access: yesInternational 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.

Assessing interdisciplinary understanding: Disciplinary crossroads in the International Baccalaureate Middle Years Programme

open access: yesThe Curriculum Journal, EarlyView.
Abstract Assessing interdisciplinary learning within school curricula remains a persistent challenge in educational research. Difficulties in articulating shared assessment criteria, alongside differing disciplinary and pedagogical perspectives, have contributed to ongoing uncertainty around how interdisciplinary learning should be evaluated.

Breaking the Activity–Stability Scaling in RuO2 via Single‐ and Dual‐Doping Strategies

open access: yesEcoEnergy, EarlyView.
Single and dual heteroatom doping redefines RuO2 for acidic oxygen evolution by synergistically tuning the electronic structure, lattice stability, and reaction pathways. Although single dopants optimize specific catalytic properties, dual dopants overcome the activity–stability trade‐off through cooperative electronic and geometric regulation ...

High‐Voltage Stability of LiCoO2 Cathode Materials Composited With Vanadium‐Based Glass Coatings

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Vanadium‐based glasses show fluidity and good wettability toward other materials at low temperatures. The controlled precipitation of nanocrystals in vanadium‐based glasses enhances the material's mechanical properties and electrical conductivity. The VPFL coatings bond to the LiCoO2 interface via chemical bonds.
