Advanced Science, Volume 13, Issue 9, 13 February 2026.This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

A 2.5 mW D‐Band Broadband Simultaneous Noise‐ and Input‐Matched InP LNA
Electronics Letters, Volume 62, Issue 1, January/December 2026.This work presents a D‐band, ultra‐low‐power, broadband two‐stage low‐noise amplifier (LNA) implemented in a 250‐nm InP DHBT process. Using a simultaneous noise and input matching technique with a gain‐boosted feedback network, the LNA achieves 6.2 dB noise figure and 27 dB gain from 130 to 155 GHz while consuming only 2.5 mW.
