Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2
Advanced Functional Materials, EarlyView.High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Millimetre-wave wideband reflection-type CPW MMIC phase shifter
Electronics Letters, 2002 A reflection-type coplanar waveguide (CPW) phase shifter fabricated using a standard monolithic microwave integrated circuit (MMIC) process is presented. Air-gap overlay CPW couplers were employed for wideband 3 dB coupling and low loss at millimetre wave. The two-stage cascaded analogue phase shifter showed insertion losses of 6.9 /spl plusmn/ 1.6 dB,
