30/20 GHz spacecraft GaAs FET solid state transmitter for trunking and customer-premise-service application [PDF]

Sixteen 30 dB 0.5 W amplifier modules were combined to satisfy the requirement for a graceful degradation. If one module fails, the output power drops by only 0.43 dB.

Photon‐to‐Heat Energy Harvesting Fluorescent Protein Coatings for Thermoelectrics

Advanced Science, EarlyView.
Fluorescent proteins (FPs) are used in light‐absorbing coatings on thermoelectric generators (TEGs) to convert light into heat and generate electricity. By tuning the properties of FP‐doped polymer matrices, photothermal efficiencies of up to 48% have been achieved.

XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates

Advanced Electronic Materials, EarlyView.
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Embedded Direct‐Written Organic Micro‐TEGs for High‐Efficiency Skin‐Heat Harvesting

Advanced Electronic Materials, EarlyView.
A finite‐element–guided design of direct‐written organic micro‐thermoelectric generators is presented for efficient skin‐heat harvesting. Embedding PEDOT:PSS/PBFDO thermoelectric legs within flexible substrates suppresses interfacial heat losses and enhances vertical heat flow.

Decoding Interfacial Charge‐Carrier Dynamics in Integrated Perovskite/Organic Solar Cells via Numerical Modeling

Advanced Energy Materials, EarlyView.
A physical framework is developed based on drift‐diffusion simulations to elucidate the operation of integrated perovskite/organic solar cells (I‐POSCs) through the lens of interfacial charge‐carrier dynamics. A stepwise analysis establishes key links between carrier transport/recombination phenomena and device performance metrics, offering valuable ...

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Self‐Driving Laboratory Optimizes the Lower Critical Solution Temperature of Thermoresponsive Polymers

Advanced Intelligent Discovery, EarlyView.
A low‐cost, self‐driving laboratory is developed to democratize autonomous materials discovery. Using this "frugal twin" hardware architecture with Bayesian optimization, the platform rapidly converges to target lower critical solution temperature (LCST) values while self‐correcting from off‐target experiments, demonstrating an accessible route to data‐
