A 120 GHz Hybrid Low Noise Amplifier in 40 nm CMOS

IEEE Access
In this paper, we present a 6-stage 120 GHz hybrid low noise amplifier (LNA) for sub-THz radar systems. To enhance the noise figure (NF) and gain performance of the LNA, we propose a hybrid architecture that utilizes a combination of 2-stage single-ended

Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

Advanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

Optimisation of short pulse multi-stage Yb fiber amplifier systems using commercial gain-modelling software [PDF]

, 2006
We demonstrate the accuracy of commercial telecommunications industry software for modelling Yb-fiber amplifiers. Simulations enabled optimisation of a broad bandwidth ultra-short pulse four-stage amplifier system. The predicted results were confirmed by

Gellan Gum Fluid Gel System for Controlled‐Delivery of Cytokine‐Licensed MSC‐EVs to Enhance Corneal Repair in Limbal Stem Cell Deficiency

Advanced Healthcare Materials, EarlyView.
Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.
